The Advanced Micro Devices AM27C400-255LE is a 4 Mbit CMOS UV Erasable Programmable Read-Only Memory (UVPROM) with a memory organization of 256K x 16 bits. This component offers an asynchronous operating mode and a maximum access time of 250ns. It features a 3-state output characteristic and operates with a supply voltage range of 4.75V to 5.25V, typically at 5V. The device is housed in a 44-terminal Ceramic Chip Carrier (CQCC) package, designed for surface mounting. Its wide operating temperature range spans from -55°C to +125°C, making it suitable for demanding industrial and defense applications. The AM27C400 series is commonly utilized in embedded systems, legacy hardware, and specialized data storage solutions where non-volatility and reprogrammability via UV erasure are required.
