Advanced Micro Devices AM27H256 ultraviolet erasable programmable read-only memory (UVPROM) offers a 262,144-bit density, organized as 32K words by 8 bits. This CMOS device features a maximum access time of 35ns, enabling high-speed operation in demanding applications. The AM27H256 series operates asynchronously and provides a 3-state output characteristic. It is housed in a 32-pin ceramic quad flat package (CQFP), specified by JESD-30 code R-CQCC-N32. Operating from a 4.5V to 5.5V supply, this component is suitable for use in industrial automation, telecommunications, and embedded systems requiring reliable non-volatile data storage. The device supports parallel programming and has a standby current of 35mA and a maximum supply current of 60mA.
