Microchip Technology, Inc. Memory 34AA02T-I/MS

The 34AA02T-I/MS is a 2Kbit I2C-compatible EEPROM memory device from Quarktwin Technology Ltd. It operates on a voltage range of 1.7V to 5.5V and features both permanent and resettable software write protection for the lower half of the memory array. The device supports a low-power CMOS technology with a typical read current of 1 mA and a standby current of 100 nA. It utilizes a 2-wire serial interface and is compatible with clock speeds of 100 kHz and 400 kHz, with a 1 MHz option for LC versions. The memory is organized as a single block of 256 x 8 bits and includes a 16-byte page write buffer, allowing for efficient data writing with a typical page write time of 3 ms. The device is rated for more than 1 million erase/write cycles and offers data retention exceeding 200 years. It is available in multiple package types, including 8-lead PDIP, SOIC, TSSOP, MSOP, TDFN, and a 6-lead SOT-23 package, and is compliant with RoHS standards. The 34AA02T-I/MS is suitable for applications requiring reliable non-volatile memory with robust write protection features.
