The Microchip Technology AT28HC256-90DM is a 32K x 8 CMOS Parallel EEPROM with a 90ns access time. This memory component offers a memory density of 262144 bits and operates asynchronously. It features an automatic write function, data polling for status indication, and a toggle bit for write completion confirmation. The device is housed in a 28-lead ceramic dual in-line package (CDIP28) with through-hole mounting. Operating over a temperature range of -40°C to +85°C, it requires a supply voltage between 4.5V and 5.5V. The AT28HC256-90DM is suitable for applications in industrial control, data logging, and embedded systems requiring non-volatile data storage. Endurance is rated at 10,000 write cycles.
