25AA010AT-I/OT

The Microchip Technology 25AA010AT-I/OT is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) accessed via a Serial Peripheral Interface (SPI) compatible serial bus. It operates with a maximum clock frequency of 10 MHz and supports a wide voltage range from 1.8V to 5.5V.

This device offers low-power CMOS technology with a maximum write current of 5 mA and a read current of 5 mA at 5.5V and 10 MHz. The standby current is a mere 5 µA at 5.5V. It is organized as 128 x 8 bits and supports write page mode for up to 16 bytes per page. Key features include sequential read capability and self-timed erase and write cycles with a maximum duration of 5 ms.

Designed for reliability, the 25AA010AT-I/OT boasts an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It also provides robust ESD protection of over 4000V. The device is available in a compact SOT-23-6 surface mount package, making it suitable for space-constrained applications.

Block write protection is supported, allowing for protection of none, 1/4, 1/2, or all of the array. Built-in write protection mechanisms include power-on/off data protection circuitry, a write enable latch, and a dedicated write-protect pin. This EEPROM is compliant with RoHS3 standards.
