The Microchip Technology AT28HC256E-90DM is a 256 Kbit (32K x 8) CMOS parallel EEPROM. This device offers a fast 90ns access time and features automatic write capabilities with data polling for status indication. Designed for robust operation, it supports 100,000 endurance cycles and operates over a -40°C to +85°C temperature range. The AT28HC256E-90DM utilizes a 5V programming voltage and is housed in a 28-lead Ceramic DIP (CDIP28) package, adhering to JESD-30 code R-GDIP-T28. Typical applications for this component include industrial control, aerospace, and defense systems requiring reliable non-volatile data storage. It supports standard parallel data transfer and includes a toggle bit for write completion detection.
