CAT34TS04VP2GT4A ON  温度及湿度传感器  汽车电子

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 **ed 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. Features
