Description

The N34TS04 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. After power?up, banks can be switched via software

command. Each of the four 1?Kb SPD EEPROM blocks can be Write

Protected by software command.
