STTS2002
2.3 V memory module temperature sensor
with a 2 Kb SPD EEPROM
Features
■ 2.3 V memory module temperature sensor with
integrated 2 Kb SPD EEPROM
■ Forward compatible with JEDEC TSE 2002a2
and backward compatible with STTS424E02
■ Operating temperature range:
– –40 °C to +125 °C
■ Single supply voltage: 2.3 V to 3.6 V
■ 2 mm x 3 mm TDFN8, height: 0.80 mm (max)
– JEDEC MO-229, WCED-3 compliant
■ RoHS compliant, halogen-free
Temperature sensor
■ Temperature sensor resolution:
programmable (9-12 bits)
0.25 °C (typ)/LSB - (10-bit) default
■ Temperature sensor accuracy (max):
– ± 1 °C from +75 °C to +95 °C
– ± 2 °C from +40 °C to +125 °C
– ± 3 °C from –40 °C to +125 °C
■ ADC conversion time: 125 ms (max) at default
resolution (10-bit)
■ Typical operating supply current: 160 µA
(EEPROM standby)
■ Temperature hysteresis selectable set points
from: 0, 1.5, 3, 6.0 °C
■ Supports SMBus timeout 25 ms - 35 ms
TDFN8
2 mm x 3 mm
(max height 0.80 mm)
2 Kb SPD EEPROM
■ Functionality identical to ST’s M34E02 SPD
EEPROM
■ Permanent and reversible software data
protection for the lower 128 bytes
■ Byte and page write (up to 16 bytes)
■ Self-time WRITE cycle (5 ms, max)
■ Automatic address incrementing
Two-wire bus
■ Two-wire SMBus/I²C - compatible serial
interface
■ Supports up to 400 kHz transfer rate
■ Does not initiate clock stretching
