Microchip Technology AT28C040-20BM is a 4-Megabit (512K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) device. This parallel interface memory offers a maximum access time of 200 nanoseconds and operates using CMOS technology. It features automatic write capabilities and data polling for efficient write operation monitoring. The device is housed in a 32-lead Ceramic Dual In-line Package (CDIP) with through-hole mounting. Designed for a wide operating temperature range of -55°C to +125°C, it supports a supply voltage from 4.5V to 5.5V. Typical applications include industrial control systems, automotive electronics, and aerospace systems requiring reliable data storage and retrieval.
