Microchip Technology, Inc. Memory - EEPROM - 25AA320AT-I/MNY 25AA320AT-I/MNY

The 25AA320AT-I/MNY is a 32Kbit Serial EEPROM from Quarktwin Technology Ltd., designed for use with a Serial Peripheral Interface (SPI). It operates within a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The memory is organized as 4096 x 8 bits and features a 32-byte page size for efficient data handling. This device incorporates low-power CMOS technology, with a maximum write and read current of 5 mA at 5.5V. It has a standby current of only 5 µA, making it suitable for power-sensitive applications. The 25AA320AT-I/MNY supports self-timed erase and write cycles, with a maximum cycle time of 5 ms. It also includes block write protection options, allowing users to protect none, 1/4, 1/2, or the entire memory array. The EEPROM is rated for high reliability, boasting an endurance of over 1 million erase/write cycles and data retention exceeding 200 years. It is also equipped with ESD protection greater than 4000V. The device is available in multiple package types, including 8-lead MSOP, PDIP, SOIC, TDFN, and TSSOP, and is compliant with RoHS standards. Additionally, it is automotive AEC-Q100 qualified, making it suitable for automotive applications.
