Detailed Description for CAT34C02HU4IGT4U5
Product Overview
The CAT34C02HU4IGT4U5 from onsemi is a non-volatile EEPROM memory IC with a 2Kbit capacity organized as 256 x 8. It communicates over an I2C interface at a 400 kHz clock frequency, with an access time of 900 ns and a word or page write cycle time of 5 ms. The device operates from a 1.7 V to 5.5 V supply and is rated for an ambient temperature range of -40°C to 85°C. It is housed in an 8-UDFN (2x3) surface-mount package with an exposed pad.
Key Features
- 2Kbit EEPROM memory organized as 256 x 8.
- I2C serial interface operating at 400 kHz.
- 900 ns access time and 5 ms word or page write cycle time.
- 1.7 V to 5.5 V supply voltage range.
- -40°C to 85°C ambient operating temperature range.
- 8-UDFN (2x3) surface-mount package with exposed pad.
Applications
- Configuration storage for embedded controller boards.
- Parameter retention in sensor modules.
- Small lookup tables for firmware-controlled equipment.
- Identification data storage for compact module assemblies.
Design & Procurement Notes
Designers can use the 1.7 V to 5.5 V supply range across low-voltage and 5 V logic domains, while the I2C 400 kHz interface and 256 x 8 organization support simple byte-oriented storage tasks. The 5 ms write cycle time should be considered in firmware timing, and the 900 ns access time indicates the read path speed. The 8-UDFN (2x3) surface-mount package with exposed pad requires a footprint and pad handling consistent with surface-mount assembly, and the -40°C to 85°C ambient range should be checked against the final enclosure environment.
