Smart-card reader ICs TDA8024 and TDA8034

These are complete, cost-efficient analog interfaces for asynchronous smart cards. They provide all the supply, protection, and control functions between a smart card and the microcontroller. The TDA8034 is the same as the TDA8024, but without a DC/DC converter. They are available with demo kits.

The TDA8024 and TDA8034 are both NDS and EMV 4.2 compliant, and they both can supply a V

CC

of 5 V to the smart card. The system supply voltage influences device selection. Use the TDA8034 when the system supply voltage is 5 V +/- 3%. This will ensure that the card V

CC

value is a minimum of 4.75 V with a current load of 65 mA. In systems that can only supply a voltage of 5 V +/- 10%, the TDA8024 is a better choice, because it can guarantee a proper value on V

CC

= 5 V. The TDA8034 is available in a 24-pin HVQFN or, to meet low-cost requirements, can be housed in a 16-pin SO package. The TDA8034 is not pin-compatible with the TDA8024, which has 28 pins.

8. Interfaces and control

8.1 8/16/32-bit microcontrollers

We offer highly-integrated and cost-effective microcontrollers, from the smallest 8-bit to the highest performing 32-bit ARM solutions.

The LPC111x family, based on Cortex-M0, is an excellent choice for standby microcontroller tasks. It can be used for power management, system and human interface monitoring (including remote control and keypad), signaling, LEDs, and more. The family delivers the outstanding performance of a 32-bit architecture, with best-in-class power consumption, and the optimized code footprint enables memory cost reduction.

The NXP approach lets designers work with a single ARM development environment to cover all their processing needs, from ARM7 and ARM9 to Cortex-M. Our portfolio also includes an industry-leading selection of enhanced 80C51.

C GPIO expanders

Our GPIO expanders make it easy to increase the number of I/O using the I 2 C-bus. Add inputs for a keypad, a switch, signal monitoring, or fan control, or add outputs for LED control, an ACPI power switch, a relay, timers, or sensors.

Combat “feature creep” by increasing the number of I/O ports instead of adding a new microcontroller. Or, enable seamless migration to a newer microcontroller and still keep the same peripherals. Using expanders eliminates costly, congested PCBs, since a trace or wire isn’t needed for each signal.

NXP offers an extremely wide selection. We have 4-, 8-, 16-, and 40-bit formats, support quasi-directional and push-pull outputs, and offer options with interrupts and/or resets — all in a wide range of packages.

C level shifters

These devices provide digital logic level translation between a host processor and a slave device. This is an important part of voltage level shifting, since the host processor’s I 2 C voltage continues to go down while the voltages used by the peripheral devices remain unchanged.

We offer a very large selection of active and passive level shifters, and have evolved our NVT20xx family to include widths of 1, 2, 3, 4, 6, 8, and 10 bits.

Discrete components for the main processing board

9.1 Power solutions

Since integrated circuits typically use a lower core supply voltage than interfaces and memory devices, most boards require a number of different supply voltages. Our power solutions include a variety of devices, including medium-power Schottky diodes, bipolar transistors, and MOSFETs, to help create efficient, cost-effective linear regulators and DC/DC converters.

 The PBSS4041PZ can be used as a linear PNP regulator to generate

2.5 and 1.5 V analog supplies. It delivers excellent gain up to 15 A

ICM while supporting 5.7 A of continuous current.

 Supporting 1.2 or 1.8 V, the PMEG2005EH, PMEG4010EH, and

PMEG4030ER are excellent options for the freewheeling Schottky diodes commonly used in DC/DC conversion.

 The BSP030, a 10 A, N-channel MOSFET in an SOT233 package, can be used as an external MOSFET for synchronous rectification.

 The TL431xxSDT series of shunt regulators, along with the BC847, a general-purpose transistor, are recommended for low-power, discrete linear voltage regulators.
