Advanced Micro Devices AM27H256-35V05LC is a 256 Kbit (32K x 8) CMOS ultraviolet erasable programmable read-only memory (UVPROM). This device offers an access time of 35ns, enabling high-speed data retrieval. Operating from a 5V supply voltage (4.75V to 5.25V), it features 3-state outputs for bus compatibility. The AM27H256 series is designed for applications requiring non-volatile code storage and data retention, commonly found in industrial control systems, telecommunications infrastructure, and legacy embedded systems. The component utilizes a CQCC32 package, a ceramic chip carrier with a window for UV erasure, and operates within a temperature range of 0°C to 70°C. Its parallel interface and asynchronous operation simplify system integration.
