93AA46C-I/ST

The Microchip Technology 93AA46C-I/ST is a 1Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for low-power applications. This device utilizes advanced CMOS technology and offers a 1Kbit memory capacity, organized as either 128 x 8 bits or 64 x 16 bits, selectable via an ORG pin.

It communicates using the industry-standard 3-wire serial Microwire interface, supporting clock frequencies up to 3 MHz. The operating voltage range is from 1.8V to 5.5V, making it suitable for various power-sensitive designs. The EEPROM features self-timed erase/write cycles with automatic erase-all before write-all functionality, and power-on/off data protection circuitry.

Packaged in an 8-TSSOP (0.173", 4.40mm Width) with surface mount mounting type, the 93AA46C-I/ST is designed for efficient integration into compact electronic systems. It operates within an industrial temperature range of -40°C to 85°C (TA). The device offers robust data retention exceeding 200 years and 1,000,000 erase/write cycles, ensuring long-term reliability.

Key features include a device status signal (Ready/Busy) and sequential read function. This EEPROM is ideal for nonvolatile memory applications where low power consumption and reliable data storage are critical.
