The Microchip Technology AT28C256E-20DM is a 262,144-bit CMOS Electrically Erasable Programmable Read-Only Memory organized as 32K words by 8 bits. This parallel interface device offers a fast 200ns access time and supports asynchronous operation. It features automatic write sequencing and data polling for efficient data management. Designed for robust performance, the AT28C256E operates over a wide temperature range of -55°C to +125°C and requires a 4.5V to 5.5V supply voltage. The component is housed in a 28-lead Ceramic Dual In-line Package (CDIP) with through-hole mounting. Applications include industrial control systems, automotive electronics, and telecommunications equipment where reliable non-volatile data storage is critical. Endurance is rated at 100,000 write cycles.
