Robust ISL8541x Sync Buck Regulators Ideal for
Industrial Applications with 3V to 36V Wide Input Range
FEATURES
With industry leading technology in power
management and analog products, Intersil
provides innovative design solutions to
maximize performance and reliability across
a broad range of industrial applications
including the smart home and smart grid, test
and measurement systems, medical devices
and factory automation. Programmable logic
controllers, distributed control systems,
smart transmitters and general purpose data
acquisition processes utilize sensors and
feedback mechanisms to monitor and control
system interactions by collecting, storing and
analyzing data.
Intersil offers a comprehensive portfolio of
highly integrated and efficient digital and analog
controllers, power modules and switching
regulators that simplify design and integration
for power designers seeking solutions for the
most complex systems.
Some of the key requirements of today’s power
management solutions include less power
consumption under various load conditions, less
space, high reliability and wide input voltage.
These requirements are driving the need for
highly efficient, wide VIN , low quiescent current
(IQ ) switching regulators in a broad range of
applications. Intersil’s ISL8541x buck regulators
efficiently down convert the DC voltage from
a power supply or battery to power multiple
microprocessors and board components, at
various voltage requirements. This helps
minimize power loss.
The ISL85410/15/18 offer designers maximum
flexibility, operating over a wide range of input
and output voltages. Since the devices are pinto-pin compatible in a 4 x 3mm package, a single
layout can be leveraged across multiple systems,
thus accelerating time to market and reducing
design cost. The ISL85412/13 are also pincompatible in a 3 x 3mm package.
•Wide input range from 3V to 36V
- From low voltage to high voltage
- Output range is also wide, 0.6V to 0.95
of VIN
•Synchronous Buck Regulator with both high
side and low side FETs integrated
- Majority of competitors use a standard
buck which will need an external
low side diode
- Savings in space, BOM cost and improves
efficiency
•Pin-to-pin 500mA (ISL85415), 800mA
(ISL85418) and 1A (ISL85410) parts
- Can interchange depending on the
final current needs for the board
(ISL85418/15/10)
•Pin-to-pin 150mA (ISL85412) and 300mA
(ISL85413) parts
- Can interchange depending on the final
current needs for the board (ISL85412/13)
•3A parts (ISL85003/A) with external sync or
adjustable soft start option
•Internal compensation
- Internal compensation requires fewer
external components. If you need to fine
tune the performance, then using external
compensation is an option.
- Savings in board space and BOM cost
•Simple and easy-to-use
- Intersil demo boards provide a full design
that is almost complete
- Compact, optimized design; not weighed
down by extraneous bells and whistles
•Light load efficiency mode
- Improves performance in low load
conditions
- Fast transition from PFM to PWM mode
allows for excellent transient performance
APPLICATIONS
•Industrial control
•Portable instrumentation
•Distributed power supplies
•Medical devices
•Cloud infrastructure

PCA9955A 16-Channel Fm+ I2C-Bus 57mA/20V
Constant Current LED Driver
Industrial or home automation system control
panels use LEDs for status indicators and for
LCD display backlighting. Elegant and userfriendly control panels are a snap to design
and cost effective when built around new
LED drivers ICs that do more than simply turn
those LEDs on and off.
Controlling an LED directly ties up an MCU IO
port pin. In addition, controlling the LED brightness through firmware PWM dimming also ties
up the processor. When there’s more than just a
couple of LEDs in your next user interface design
add a dedicated LED driver IC. The latest LED
driver from NXP (PCA9955A) requires only two
IO port pins for control over the ubiquitous I2Cbus that’s built into most MCU ICs. Up to sixteen
channels of LEDs can be controlled for ON-OFF
or brightness (using PWM). These channels can
also be assigned to groups for global dimming;
ideal if your control panel is outdoors in both
sunlight and moonlight.
A recent addition to these clever LED drivers is
the ability to perform gradation – an automatic
cycle that controls ramp up and ramp down
of LED brightness. This is commonly used to
indicate a sleep state when powered down, and
only a tell-tale LED is seen ‘breathing’.
Registers in this LED driver are easily programmed
with ‘ramp up’, ‘hold’, ’ramp down’ and ‘off’
durations, so that LED gradation (blinking
and breathing) gives the system architect unique
signaling options with no burden on the
MCU overhead.
For backlighting with a string of LEDs this LED
driver IC provides constant current (for better
LED matching) and tolerates up to 20V for long
strings of LEDs.
Each channel can sink over 50mA with no
additional components needed, not even
traditional LED ballast resistors. LEDs connect
directly to this LED driver IC, which requires only
a single global maximum current setting resistor.
APPLICATIONS
More reliable end products result from this LED
driver’s on-chip fault detector circuitry that
reports both open and shorted LEDs.
Finally, with sixteen independently controlled
channels, color mixing of RGB LED clusters opens
your next control panel design up to end user
customization.

The URG series, like its cousin RGLL, boasts the
industry’s best absolute tolerance ±0.01%, and
smallest TCR ±2ppm/°C, as thin film chip resistors.
Because it is made of thin film, it maintains all
the thin film advantages such as low noise
(-25dB to -35dB) and frequency performance
(up to 1GHz). In addition, the URG series shows
superb linearity in TCR as shown.
The RG series has excellent reliability and the
URG‘s reliability is even better. For example,
the maximum drift for load life (+70°C, 2000
hours) is specified as ±0.02% (RG ±0.05%),
the humidity bias (85/85, 2000 hours) drift
is specified as ±0.05% (RG ±0.1%, refer
to the graph), the temperature cycle drift
(-65°C/+150°C, 100 cycles) is specified as
±0.02% (RG ±0.1%), and the high temperature
exposure (+155°C, 100 hours) drift is specified
as ±0.02% (RG ±0.1%). The URG series is also
highly stable under any environmental conditions
including sulfuric atmosphere.

DESIGN NOTE
Quad SPI Flash: A Simpler, Faster Alternative to Standard SPI Flash
When Adding External Memory to 32-bit MCU Systems
By: Frederik De Swaef, Field Applications Engineer, Macronix and Francesco Petruzziello, MCU Product Application Engineer, NXP
512Mb, and are suitable for both fast data
storage and in-place code execution.
The modern 32-bit microcontroller is a
remarkably capable device, but its abilities
have given rise to a problem for the design
engineers who use them; faced with evergrowing demand for more features, such as
more detailed graphics or a greater range of
languages to be supported in the user interface, designers are finding themselves limited
by the small size of the typical MCU’s on-chip
Flash memory.
Quad SPI is a modified serial peripheral interface
which is capable of communicating on four data
lines; traditional SPI uses only a single line. This
multiplies the data throughput by almost four
times, and makes high-performance execution in
place possible. Compared to parallel NOR Flash
with a 16-bit data bus, Quad SPI NOR Flash can
achieve almost twice the total throughput (see
Figure 1).
Today, 32-bit MCUs are normally supplied with
an on-chip Flash memory no larger than 1Mb.
And the options for extending this on-board
memory have changed in recent years; it is now
rare to add external parallel Flash, since few
MCUs support the parallel external memory
interface. One of the reasons for this lack of
support is the number of pins a parallel Flash
needs for a 8- or 16-bit data bus and 20 or more
address and control lines.
SPI NOR Flash is another option that the design
could consider, but this memory type is much
slower than on-chip and parallel Flash. Further,
it is normally impossible to execute code from
SPI Flash; even if it is possible, the performance
is poor.
To solve this problem of adding external Flash
memory, NXP Semiconductors has developed
a new, easy-to-use external memory interface.
Called SPI Flash Interface (SPIFI), it is intended
for use with the popular Quad SPI NOR Flash
memory type, which is cost effective and
provides a wide choice of densities.
SPIFI is available today in the LPC1800 family of
ARM® Cortex®-M3 MCUs from NXP, and in the
LPC4000 and LPC4300 families of ARM CortexM4MCUs. (SPIFI support will be added to more
NXP MCUs, in future). SPIFI support means that
these controllers can benefit from the proven
Quad SPI memory technology provided by the
MX25 range of Serial NOR Flash devices from
Macronix. These range in size from 8Mb to
24
Figure 1: Quad SPI NOR Flash offers throughput nearly two
times greater than that of parallel NOR Flash
Throughput is not Quad SPI’s only advantage;
requiring only six connections between the MCU
and the memory IC, routing is far less complex
than that of a parallel Flash design, which calls
for between 30 and 45 tracks.
Macronix Quad SPI Flash choices
The MX25 series of Quad SPI Flash memories
from Macronix is available in various small
8- and 16-pin packages. These SOP, WSON and
USON devices have a very small board footprint.
Macronix has taken care to give various MX25
devices of different memory densities the same
footprint or a compatible footprint, so that OEMs
can migrate from one density to another without
making any changes to board layout. Only when
migrating to a density higher than 128Mb does
the designer have to implement minor software
changes to support 4-byte addressing.
In NXP MCUs, the SPIFI interface is directly
connected to the ARM core’s AMBA High
performance Bus (AHB), which means that the
Quad SPI Flash is mapped and accessible for
transfer via I/O or DMA channels (see Figure 2).
When executing in place, instructions are loaded
into the SPIFI buffers directly from the external
Flash, with no software overhead.
The Quad SPI Flash itself is controlled by five
registers. These registers set the configuration
and commands for reading and retrieving status
information, and are transparently used by the
on-chip ROM driver and the SPIFI library. They
can also be directly accessed by the user
application if desired.
Figure 2: The Quad SPI Flash memory is directly connected to
the AHB via SPIFI
The MCU’s SPIFI hardware controls the process
for reading from the Quad SPI Flash. If code is
stored there, the hardware will fetch it automatically in accordance with the register settings,
with no software intervention. Initiation of
writing and erasing operations is controlled by
software settings.
The commands for data transfer have the same
structure as those of a conventional SPI Flash
memory; they specify the command, address and
data for reading and writing (see Figure 3). With
Quad SPI Flash, the command will be sent on
one line, and the address on four lines. Data are
also moved from Flash on four lines. The use of
four lines means that sending a 24-bit or 3-byte
address requires only six clock cycles, instead
of 24 in an SPI Flash memory. Similarly, 1 byte of
data is received in two clock cycles instead
of eight.

Figure 3: The Quad SPI Flash command structure is similar to
that of conventional SPI Flash
The Macronix MX25 Flash memories are capable
of running at a clock frequency up to 104MHz
during all operations. For read operations, the
designer must take into account the need for
dummy cycles after transferring the address
when calculating the access time required
to fetch the first byte. After the first byte, the
address will automatically be incremented and
data will be sent out with no additional access
time until the Select pin goes high again. This
enables a fast data throughput when reading
sequential data.
Random read operations, such as branching in
instructions, must use the Enhanced Read mode.
This mode enables data to be read without
sending a Read command. The address alone
needs to be provided, saving eight clock cycles.
The Enhanced Read mode is set by toggling bits
in the dummy cycles of the first read operation.
All subsequent reads only need to transmit the
address.
NXP MCUs’ Support for Quad SPI Flash
Some NXP ARM Cortex-M MCUs have no onchip Flash memory. This includes the LPC1810,
LPC1820, LPC1830 and LPC1850, and also the
LPC4310, LPC4320, LPC4330, LPC4350 and
LPC4370. All these devices, however, can use
external Quad SPI Flash as their sole non-volatile
memory for data and code storage and for inplace execution, enjoying outstanding read and
write performance.
The Macronix MX25Lxxx35E/F series is ideal
for this, offering densities from 8Mb to 512Mb
(64MB) in 8-pin or 16-pin packages (see Table 1).

Table 1: Macronix offers a broad choice of Quad SPI NOR Flash memories
The designer has the flexibility to migrate during
development without being tied to one density,
while benefiting from high performance combined with a very low bill of materials cost.
SPIFI is also implemented in LPC MCUs which do
feature on-chip Flash. In this case, the function
of the Quad SPI external Flash is to extend the
on-chip memory, providing extra code- or datastorage capability.
This is often required in graphical user interfaces
(GUIs). Traditionally in these applications, the
image data are stored in an external SPI or
parallel Flash, with the disadvantages described
above. Data often need to be shifted from the
external device into internal or external RAM,
and then moved again to the display itself. This
means that the data have to be moved twice
before being displayed.
Conclusion
When a 32-bit MCU has no on-chip Flash memory,
or its on-board Flash is not large enough, the
ideal solution is to add a Quad SPI external Flash
memory. Quad SPI Flash supported by the SPIFI
interface implemented in NXP ARM Cortex-M
MCUs removes the complexity of designing with
external parallel Flash, reducing pin count and
offering better performance. This makes the
combination a good choice for many applications
in industrial equipment, consumer devices and
white goods.

The high throughput of the MX25 Quad SPI Flash
and the memory-mapped SPIFI interface allow
data to be shifted directly from external Flash to
the display. Now, the data are moved only once
and the amount of RAM needed as well as the
memory bus load can be markedly reduced.
