Detailed Description for CAT34C02HU4IGT4A
Product Overview
The CAT34C02HU4IGT4A from onsemi is a 2 Kbit nonvolatile EEPROM memory IC that communicates over an I2C serial interface. The device is organized as 256 x 8 bits and operates with a clock frequency of 400 kHz, an access time of 900 ns, and a word or page write cycle time of 5 ms. It supports a supply voltage range from 1.7 V to 5.5 V and is specified for an operating temperature range from -40°C to 85°C. The surface-mount package is an 8-UFDFN exposed-pad format with the 8-UDFN-EP (2x3) package designation.
Key Features
- 2 Kbit EEPROM memory with a 256 x 8 organization for byte-oriented serial access.
- I2C interface with 400 kHz clock frequency and 900 ns access time.
- Nonvolatile storage technology suitable for retaining small data sets without continuous power.
- 5 ms word or page write cycle time for programming operations.
- 1.7 V to 5.5 V supply voltage range and -40°C to 85°C operating temperature range.
- Surface-mount 8-UFDFN exposed-pad package with the 8-UDFN-EP (2x3) designation.
Applications
- Nonvolatile storage of configuration parameters in embedded controllers.
- Retention of calibration data for measurement or sensing modules.
- Small-capacity serial data storage for host systems using an I2C bus.
- Settings memory in electronic assemblies requiring surface-mount packaging.
Design & Procurement Notes
Design considerations should include the 256 x 8 memory organization, I2C bus timing at 400 kHz, and the 900 ns access time when planning controller firmware and bus communication. The 5 ms word or page write cycle time may require write pacing in the application logic. The 1.7 V to 5.5 V supply range should be checked against the system power rail, while the -40°C to 85°C operating temperature range should be verified against the enclosure and ambient conditions. For layout, the 8-UFDFN exposed-pad package with the 8-UDFN-EP (2x3) designation requires a matching land pattern and pad geometry. Procurement should verify the exact manufacturer part number CAT34C02HU4IGT4A to ensure the selected package and electrical interface match the board design.
