Advanced Micro Devices AM27H256-55-BUA is a 32K x 8 bit UV Erasable Programmable Read-Only Memory (UVPROM) device featuring a 55ns access time. This CMOS component operates asynchronously with a 3-state output characteristic and is organized as 32,768 words by 8 bits, providing a total memory density of 262,144 bits. The device supports a wide operating temperature range from -55°C to +125°C and utilizes a 5V nominal supply voltage, with a maximum of 5.5V. Packaged in a 32-terminal ceramic quad flat chip carrier (CQCC32) with a window for UV erasure, this surface-mount component is suitable for applications requiring non-volatile data storage in demanding environments. Industries such as aerospace, defense, and industrial automation often utilize such robust memory solutions for firmware and configuration data. The AM27H256 series is known for its reliability and performance under harsh conditions.
