Microchip 93AA76/86 1.8V Microwire Serial EEPROM Datasheet
This document is a technical datasheet for the Microchip Technology Inc. 93AA76/86 series of Electrically Erasable PROMs (EEPROM). These devices are designed as low-power CMOS technology solutions for nonvolatile memory applications, offering single supply operation down to 1.8V.
The memory organization is configurable via an ORG pin: the 93AA76 provides either 1024 x 8 or 512 x 16-bit configurations, while the 93AA86 offers 2048 x 8 or 1024 x 16-bit options. Key features include self-timed erase and write cycles, automatic ERASE before WRAL, power on/off data protection circuitry, and a Program Enable (PE) pin for write-protection.
