Intel MD27256-20 is a 32K x 8 UV-erasable, programmable read-only memory (UVPROM) device. This MOS technology component offers an asynchronous operating mode with a maximum access time of 200ns. The memory density is 262144 bits, organized as 32,768 words by 8 bits. It features common I/O and 3-state outputs. The MD27256-20 is housed in a 28-terminal ceramic dual in-line package (CDIP28) with through-hole mounting. Operating temperature ranges from -55°C to 125°C. The device requires a 5V nominal supply voltage and a 12.5V programming voltage. It is suitable for applications in industrial control, telecommunications, and legacy system upgrades where non-volatile program storage is required. Screening is compliant with 38535Q/M, 38534H, and 883B standards.
