Intel AD87C257-200V05 is a 32K x 8 bit CMOS UV EPROM with a maximum access time of 200ns. This asynchronous memory component features a common I/O configuration and 3-state outputs, packaged in a 28-lead ceramic dual in-line package (CDIP28). With a memory density of 262,144 bits, it operates from a nominal 5V supply voltage and is designed for a wide operating temperature range from -40°C to +125°C. Applications for this technology include industrial control, telecommunications, and legacy system upgrades where reliable, non-volatile program storage is essential. The AD87C257 series is suitable for designs requiring robust data retention and standard parallel interface capabilities.
