CAT34C02VP2IGT4A

Product Overview

The CAT34C02VP2IGT4A from onsemi is a non-volatile EEPROM memory IC with 2 Kbit of storage organized as 256 x 8 bits. It communicates over an I2C interface at a clock frequency of 400 kHz and has a 900 ns access time and a 5 ms write cycle time for word or page writes. The device operates from a 1.7 V to 5.5 V supply and is specified for an ambient temperature range of -40°C to 85°C. It is offered in a surface-mount 8-WFDFN exposed-pad package with an 8-TDFN (2 x 3) device package.

Key Features

• 2 Kbit EEPROM memory with a 256 x 8 organization.
• I2C serial interface operating at 400 kHz.
• 900 ns access time.
• 5 ms write cycle time for word or page writes.
• 1.7 V to 5.5 V supply voltage range.
• -40°C to 85°C operating temperature range.
• Surface-mount 8-WFDFN exposed-pad package with 8-TDFN (2 x 3) device package.

Applications

• Storing calibration coefficients and configuration parameters in embedded measurement modules.
• Retaining device identification, serial numbers, or settings across power cycles.
• Holding small status, usage, or error counters in systems using 1.7 V to 5.5 V supplies.

Design & Procurement Notes

Design and procurement considerations: The 2 Kbit capacity and 256 x 8 organization make the device suitable for small data sets rather than bulk storage. Host software should account for the 400 kHz I2C clock frequency, the 900 ns access time, and the 5 ms write cycle time when scheduling read and write transactions. Board layout should use a footprint compatible with the 8-WFDFN exposed-pad package and the 8-TDFN (2 x 3) device package. The 1.7 V to 5.5 V supply range and -40°C to 85°C ambient range should be checked against the actual system environment.
