Texas Instruments TMS87C257 Series CMOS UVPROM, part number TMS87C257-2JE, offers a 32K x 8 memory organization with a 262K bit density. This asynchronous memory component features a maximum access time of 200ns and operates from a 4.75V to 5.25V supply range. The TMS87C257-2JE utilizes common I/O with 3-state outputs and is housed in a 28-terminal CDIP package, specifically a ceramic, glass-sealed, dual in-line package with a window for UV erasure. Its through-hole mounting and parallel interface make it suitable for applications in industrial control, telecommunications, and embedded systems requiring non-volatile program storage and field updates. The operating temperature range is -40°C to +85°C.
