N34TS04 Datasheet, PDF (1/18 Pages) ON Semiconductor – Digital Output Temperature Sensor

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