CAT34TS04 Digital Output Temperature Sensor with On-board SPD EEPROM Description The CAT34TS04 is a combination Temperature Sensor (TS) and 4−Kb of Serial Presence Detect (SPD) EEPROM, which implements the JEDEC TSE2004av DDR4 specification and supports the Standard (100 kHz), Fast (400 kHz) and Fast Plus (1 MHz) I2C protocols. 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. One of the two available 2−Kb SPD EEPROM banks (referred to as SPD pages in the TSE2004av specification) is activated for access at power−up.
