STMicroelectronics M27C256B-12F1 is a 256 Kbit UV EPROM memory device featuring a parallel interface. This non-volatile memory component offers an access time of 120 ns and is organized as 32K x 8. The device operates within a supply voltage range of 4.5V to 5.5V. Packaged in a 28-lead Ceramic Dual In-line Package (CDIP) with a frit-seal window for UV erasure, it is designed for through-hole mounting. This EPROM technology is suitable for applications requiring reliable, mask-ROM-like data storage and retrieval, commonly found in industrial control systems, legacy telecommunications equipment, and embedded systems where firmware updates are infrequent. The operating temperature range is 0°C to 70°C.
