ST:Temp sensors suit DRAM modules

Intended for monitoring the temperature of the DIMMs (dual in-line memory modules) used in personal computers, the STTS424 and STTS424E02 application specific digital temperature-sensor chips are fully compliant with the JEDEC JC42.4 specification. The STTS424 is a standalone digital temperature sensor, while the STTS424E02 integrates the temperature sensor with a 2-Kbit Serial Presence Detect (SPD) EEPROM.

Features include a supply current if 100 µA at 3.3 V, a supply voltage from 2.7 to 3.6 V, an accuracy of ¡À 1¡ã, over 75¡ã to 125¡ãC, and an operating temperature from ¨C40¡ã to 125¡ãC. Both devices communicate with the CPU chipset through an I2C/SMBus-compatible serial bus, and are available in DFN8 and TSSOP8 packages. (From $0.70 ea/large
