Integrated EEPROM and Digital Temperature Sensor Renesas TSE2004GB2C0NCG8 with Open Drain Event Pin
Renesas TSE2004GB2C0 Digital Temperature Sensor with Integrated 4Kbit EEPROM
Product Overview
The Renesas TSE2004GB2C0 is a versatile digital temperature sensor featuring user-programmable registers for flexible temperature sensing applications. It offers programmable temperature limits and hysteresis for event communication via an open-drain EVENT_n pin, which can be configured as an active-low or active-high comparator output or a temperature event interrupt. The device utilizes an industry-standard 2-wire I2C/SMBus serial interface, supporting up to eight devices on the bus. Integrated within the TSE2004GB2C0 is a 4Kbit (512 bytes) Serial EEPROM, organized into two 256-byte pages, each comprising two 128-byte blocks. This EEPROM can be selectively locked at the block level, making it ideal for storing Serial Presence Detect (SPD) data in DIMM modules. Typical applications include DIMM modules (DDR3, DDR4), servers, laptops, PCs, industrial temperature monitors, and hard disk drives.
