CAT34TS02
Digital Output Temperature
Sensor with On-board SPD
EEPROM
Description
The CAT34TS02 combines a JC42.4 compliant Temperature Sensor
(TS) with 2Kb 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 opendrain EVENT
pin.
The integrated 2Kb SPD EEPROM is internally organized as 16
pages of 16 bytes each, for a total of 256 bytes. It features a page write
buffer and supports both the Standard (100 kHz) as well as Fast
(400 kHz) I
2
C 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.
