N34TS04: Digital Output Temperature Sensor with On-board SPD EEPROM

Description: The N34TS04 is a combination Temperature Sensor (T...
  • The N34TS04 is a combination Temperature Sensor (TS) and 4-Kb of Serial Presence Detect (SPD) EEPROM, which implements the JEDEC TSE2004av DDR4 specification. 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 4-Kb memory is partitioned into two individually addressable 2-Kb banks (referred to as SPD pages in the TSE2004av specification). Each bank contains two 1-Kb blocks, which can be Write Protected via Reversible Software Write Protect (RSWP) commands. The SPD EEPROM features a 16-byte wide write buffer and supports the Standard (100 kHz), Fast (400 kHz) and Fast Plus (1 MHz) I2C protocols.
