Microchip Technology, Inc. Memory 25AA010A-I/ST

The 25AA010A-I/ST is a 1 Kbit Serial EEPROM from Lingto Electronic Limited, designed for use with a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The device features a low-power CMOS technology, with a maximum write and read current of 5 mA at 5.5V, and a standby current of only 5 ¬µA. This EEPROM is organized as 128 x 8 bits and supports write page mode for up to 16 bytes, as well as sequential read operations. It includes self-timed erase and write cycles with a maximum duration of 5 ms. The device also offers block write protection, allowing users to protect none, 1/4, 1/2, or the entire memory array. Built-in write protection features include power-on/off data protection circuitry and a write-protect pin. The 25AA010A-I/ST is rated for high reliability, with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It is available in various package types, including 8-lead PDIP, SOIC, MSOP, TSSOP, DFN, and SOT-23. The device is compliant with RoHS standards and is suitable for industrial applications with operating temperatures ranging from -40¬8C to +85¬8C, as well as automotive applications up to +125¬8C.
