Description
1 Description
STTS3000
The STTS3000 is targeted for DIMM modules in mobile personal computing platforms
(laptops), servers and other industrial applications. The thermal sensor (TS) in the
STTS3000 is compliant with the JEDEC specification TS3000 which defines memory module thermal sensors requirements for mobile platforms.
The TS provides space as well as cost savings for mobile and server platform dual inline memory modules (DIMM) manufacturers, as it is packaged in the compact 2 mm x 3 mm
8-lead TDFN package with a thinner maximum height of 0.80 mm. The DN package is compliant to JEDEC MO-229, variation WCED-3.
The digital temperature sensor has a programmable 9-12 bit analog-to-digital converter
(ADC) which monitors and digitizes the temperature to a resolution of up to 0.0625 °C. The default resolution is 0.25 °C/LSB (10-bit). The typical accuracies over these temperature ranges are:
±2 °C over the full temperature measurement range of –40 °C to 125 °C
±1 °C in the +40 °C to +125 °C active temperature range, and
±0.5 °C in the +75 °C to +95 °C monitor temperature range
The temperature sensor in the STTS3000 is specified for operating at supply voltages from
2.3 V to 3.6 V. Operating at 3.3 V, the typical supply current is 160 µA (includes SMBus communication current).
The onboard sigma-delta ADC converts the measured temperature to a digital value that is calibrated in °C. For Fahrenheit applications, a lookup table or conversion routine is required. The STTS3000 is factory-calibrated and requires no external components to measure temperature.
The digital temperature sensor has user-programmable registers that provide the capabilities for DIMM temperature-sensing applications. The open drain event output pin is active when the monitoring temperature exceeds a programmable limit, or it falls above or below an alarm window. The user has the option to set the event output as a critical temperature output. This pin can be configured to operate in either a comparator mode for thermostat operation or in interrupt mode.

STTS3000 Serial communications
2.1
Note:
The STTS3000 has a simple 2-wire SMBus/I 2 C-compatible digital serial interface which allows the user to access the data in the temperature register at any time. It communicates via the serial interface with a master controller which operates at speeds of up to 400 kHz. It also gives the user easy access to all of the STTS3000 registers in order to customize device operation.
Device type identifier (DTI) code
The JEDEC temperature sensor has its own unique I
2
C address which ensures that there are no compatibility or data translation issues. The DTI code is the unique 4-bit address

Operation
3 Operation
STTS3000
The STTS3000 continuously monitors the ambient temperature and updates the temperature data register. Temperature data is latched internally by the device and may be read by software from the bus host at any time.
The SMBus/I 2 C slave address selection pins allow up to 8 such devices to co-exist on the same bus. This means that up to 8 memory modules can be supported, given that each module has one such slave device address slot.
After initial power-on, the configuration registers are set to the default values. The software
can write to the configuration register to set bits per the bit definitions in Section 3.1:
3.1 SMBus/I
2
C communications
The registers in this device are selected by the pointer register. At power-up, the pointer register is set to “00”, which is the capability register location. The pointer register latches the last location it was set to. Each data register falls into one of three types of user accessibility:
1.
Read-only
3. WRITE/READ same address
A WRITE to this device always includes the address byte and the pointer byte. A WRITE to any register other than the pointer register, requires two data bytes.
Reading this device is achieved in one of two ways:
• If the location latched in the pointer register is correct (most of the time it is expected that the pointer register points to one of the read temperature registers because that is the data most frequently read), then the READ can simply consist of an address byte, followed by retrieval of the two data bytes.
• If the pointer register needs to be set, then an address byte, pointer byte, repeat start, and another address byte accomplishes a READ.
The data byte transfers the MSB first. At the end of a READ, this device can accept either an acknowledge (ACK) or no acknowledge (No ACK) status from the master. The No ACK status is typically used as a signal for the slave that the master has read its last byte. This device subsequently takes up to 125 ms to measure the temperature for the default temperature resolution.

STTS3000 Temperature sensor registers
4 Temperature sensor registers
The temperature sensor component is comprised of various user-programmable registers.
These registers are required to write their corresponding addresses to the pointer register.
They can be accessed by writing to their respective addresses (see
). Pointer register bits 7 - 4 must always be written to '0' (see
). This must be maintained, as not setting these bits to '0' may keep the device from performing to specifications.
The main registers include:
•
Capability register (read-only)
•
Configuration register (read/write)
•
Temperature register (read-only)
•
Alarm temperature trip registers (read/write) , including
– Alarm temperature upper boundary,
– Alarm temperature lower boundary, and
– Critical temperature.
•

STTS3000 Temperature sensor registers
The 16-bit configuration register stores various configuration modes that are used to set up the sensor registers and configure according to application and JEDEC requirements (see
).
All event thresholds use hysteresis as programmed in register address 0x01 (bits 10 through 9) to be set when they de-assert.
The interrupt mode allows an event to occur where software may write a '1' to the clear event bit (bit 5) to de-assert the event Interrupt output until the next trigger condition occurs.
The comparator mode enables the device to be used as a thermostat. READs and WRITEs on the device registers do not affect the event output in comparator mode. The event signal remains asserted until temperature drops outside the range or is re-programmed to make the current temperature “out of range”.
Note:
The STTS3000 features a shutdown mode which disables all power-consuming activities
(e.g. temperature sampling operations), and leaves the serial interface active. This is selected by setting shutdown bit (bit 8) to '1'. In this mode, the devices consume the minimum current (I
SHDN
), as shown in
.
Bit 8 cannot be set to '1' while bits 6 and 7 (the lock bits) are set to '1'.
The device may be enabled for continuous operation by clearing bit 8 to '0'. In shutdown mode, all registers may be read or written to. Power recycling also clears this bit and returns the device to continuous mode as well.

Hysteresis applies to all limits when the temperature is dropping below the threshold so that once the temperature is above a given threshold, it must drop below the threshold minus the hysteresis in order to be flagged as an interrupt event. Note that hysteresis is also applied to the EVENT pin functionality. When either of the lock bits is set, these bits cannot be altered.
Reserved for future use. These bits always read ‘0’ and writing to them has no effect. For future compatibility, all RFU bits must be programmed as ‘0’.
1. As this device is used in DIMM (memory modules) applications, it is strongly recommended that only the active-low polarity
(default) is used. This provides full compatibility with the STTS424. This is the recommended configuration for the
STTS3000.
2. The actual incident causing the event can be determined from the read temperature register. Interrupt events can be cleared by writing to the clear event bit (writing to this bit has no effect on overall device functioning).
3. Writing to this register has no effect on overall device functioning in comparator mode. When read, this bit always returns a logic '0' result.

4.2.5 Event output pin functionality
STTS3000
The STTS3000 EVENT pin is an open drain output that requires a pull-up to V
DD
on the system motherboard or integrated into the master controller. EVENT has three operating modes, depending on configuration settings and any current out-of-limit conditions. These modes are interrupt, comparator or critical.
In interrupt mode the EVENT pin remains asserted until it is released by writing a ‘1’ to the
“Clear Event” bit in the status register. The value to write is independent of the EVENT polarity bit.
In comparator mode the EVENT pin clears itself when the error condition that caused the pin to be asserted is removed.
In critical mode the EVENT pin is asserted only if the measured temperature exceeds the critical limit. Once the pin has been asserted, it remains asserted until the temperature drops below the critical limit minus hysteresis.
illustrates the operation of the different modes over time and temperature.
When the hysteresis bits (bits 10 and 9) are enabled, hysteresis may be used to sense temperature movement around trigger points. For example, when using the “above alarm window” bit (temperature register bit 14, see
) and hysteresis is set to
3 °C, as the temperature rises, bit 14 is set (bit 14 = 1). The temperature is above the alarm window and the temperature register contains a value that is greater than the value set in
the alarm temperature upper boundary register (see Table 16 on page 24
).
If the temperature decreases, bit 14 remains set until the measured temperature is less than or equal to the value in the alarm temperature upper boundary register minus 3 °C (see
Figure 8 on page 19 and Table 10 on page 19
for details.
Similarly, when using the “below alarm window” bit (temperature register bit 13, see
Table 12 on page 22 ) is set to '0'. The temperature is equal to or greater than the value set
in the alarm temperature lower boundary register (see
temperature decreases, bit 13 is set to '1' when the value in the temperature register is less than the value in the alarm temperature lower boundary register minus 3 °C (see
Figure 8 on page 19 and Table 10 on page 19
for details.
The device retains the previous state when entering the shutdown mode. If the device enters the shutdown mode while the EVENT pin is low, the shutdown current increases due to the additional event output pull-down current.

Obsolete Product(s) - Obsolete Product(s)
Systems that use the active high mode for Event output must be wired point-to-point between the STTS3000 and the sensing controller. Wire-OR configurations should not be used with active high Event output since any device pulling the Event output signal low masks the other devices on the bus. Also note that the normal state of Event output in active high mode is a ‘0’ which constantly draws power through the pull-up resistor.
DocID017195 Rev 3 21/40
Temperature sensor registers STTS3000
This 16-bit, read-only register stores the temperature measured by the internal band gap TS
. When reading this register, the MSBs (bit 15 to bit 8) are read first, and then the LSBs (bit 7 to bit 0) are read. The result is the current-sensed temperature.
The data format is 2s complement with one LSB = 0.25 °C for the default resolution. The
MSB has a 128 °C resolution.
The trip status bits represent the internal temperature trip detection, and are not affected by the status of the event or configuration bits (e.g. event output control or clear event). If neither of the above or below values are set (i.e. both are 0), then the temperature is exactly within the user-defined alarm window boundaries.
The 16-bit value used in the trip point set and temperature read-back registers is 2s complement, with the LSB equal to 0.0625 °C (see
). For example:
1.
a value of 019C h represents 25.75 °C,
2. a value of 07C0 h represents 124 °C, and
3. a value of 1E74 h represents –24.75 °C
All unused resolution bits are set to zero. The MSB has a resolution of 128 °C. The
STTS3000 supports programmable resolutions (9-12 bits) which is 0.5 to 0.0625 °C/LSB.
The default is 0.25 °C/LSB (10 bits) programmable.
The upper 3 bits indicate trip status based on the current temperature, and are not affected by the event output status.

The device provides a comparison window with an upper temperature trip point in the alarm upper boundary register, and a lower trip point in the alarm lower boundary register. When enabled, the event output is triggered whenever entering or exiting (crossing above or below) the alarm window.
The device can be programmed in such a way that the event output is only triggered when the temperature exceeds the critical trip point. The critical temperature setting is programmed in the critical temperature register. When the temperature sensor reaches the critical temperature value in this register, the device is automatically placed in comparator mode, which means that the critical event output cannot be cleared by using software to set the clear event bit.
