M87C257-15F6 Description

Short technical summary and product information.

The M87C257-15F6 is a 256Kbit (32K x 8) ultraviolet-erasable programmable read-only memory (UV EPROM) from STMicroelectronics. This non-volatile memory device uses a parallel interface for high-speed data access, with a specified access time of 150 ns. It is designed for applications requiring reliable, long-term code or data storage that can be reprogrammed using UV light erasure.

 

Operating from a 4.5V to 5.5V supply, the device draws 30 mA active current and 100 µA in standby. Programming requires a 12.75V supply and takes approximately 3 seconds. The M87C257-15F6 is housed in a 28-CDIP (0.600", 15.24mm) frit seal package with a window for UV erasure, making it suitable for through-hole mounting in development and production systems.
