The Intel MR27256-20 is a 32K x 8 bit UV Erasable Programmable Read-Only Memory (UVPROM) operating with a maximum access time of 200ns. This MOS technology device features a common I/O configuration and 3-state output characteristics. It is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) with a rectangular package shape and quad terminal positioning. The memory density is 262144 bits, organized as 32,768 words of 8 bits each. This component supports asynchronous operation and is designed for surface mounting with a terminal pitch of 1.270mm. Operating across a temperature range of -55°C to +125°C, it requires a nominal supply voltage of 5V and has a maximum supply current of 125mA. Programming is achieved with a voltage of 12.5V. This component has been manufactured to meet stringent quality standards, including MIL-STD-883B. Applications include industrial control systems, telecommunications equipment, and legacy system upgrades.
