Product Overview
Product Description
The CAT34TS02 combines a JC42.4 compliant Temperature Sensor (TS) with 2-Kb of Serial Presence Detect (SPD) EEPROM.

The TS measures temperature at least 10 times every second. Temperature readings can be retrieved by the host via the serial interface, and are compared to high, low and critical trigger limits stored into internal registers. Over or under limit conditions can be signaled on the open-drain EVENT pin.

The integrated 2-Kb SPD EEPROM is internally organized as 16 pages of 16 bytes each, for a total of 256 bytes. It features a 16-byte page write buffer and supports both the Standard (100 kHz) as well as Fast (400 kHz) I2C protocol.

Write operations to the lower half memory can be inhibited via software commands. The CAT34TS02 features Permanent, as well as Reversible Software Write Protection, as defined for DDR3 DIMMs.
