Advanced Micro Devices AM27H256 series UVPROM, part number AM27H256-70-BUA, offers a 32K x 8 memory organization with a density of 262,144 bits. This CMOS device provides a maximum access time of 70ns and operates asynchronously. The component is housed in a 32-terminal CQCC32 package, utilizing a ceramic, metal-sealed cofired construction for robust performance. Designed for demanding applications, it supports a wide operating temperature range from -55°C to +125°C. Typical applications include industrial control systems, avionics, and legacy system upgrades where reliable, non-volatile storage is critical. The AM27H256-70-BUA features 3-state outputs and a standby current of 35mA, with a maximum supply current of 60mA, operating from a 5V supply voltage. Its surface-mount capability and LCC32 package equivalence further enhance its integration into complex designs.
