Advanced Micro Devices AM27H256-45DE is a 32K x 8 UV Erasable Programmable Read-Only Memory (UVPROM) utilizing advanced CMOS technology. This component offers a maximum access time of 45ns, ensuring rapid data retrieval. The memory organization of 32,768 words by 8 bits provides a total density of 262,144 bits. Designed for asynchronous operation, the AM27H256 series features a 3-state output for flexible bus interfacing. It operates from a 4.5V to 5.5V supply range with a nominal 5V requirement and exhibits a low standby current of 35mA. This through-hole component is housed in a 28-pin ceramic dual in-line package (CDIP) with a glass-sealed window for UV erasure, suitable for applications requiring non-volatile program storage. The operating temperature range spans from -55°C to +125°C, making it robust for demanding environments in industrial and military systems.
