Microchip Technology's 27C256-20B-UB is a 32K x 8 CMOS EPROM, offering a 262,144-bit storage capacity. This component features a maximum access time of 200ns and operates asynchronously with 3-state outputs. Designed for a broad operating temperature range from -55°C to +125°C, it utilizes a 32-terminal ceramic quad flat pack (CQCC32) package with a 1.27mm terminal pitch. The device supports a nominal supply voltage of 5V and is suitable for applications requiring robust non-volatile memory, including industrial control, telecommunications infrastructure, and embedded systems. Its CMOS technology ensures low standby and operating currents, with a standby current maximum of 0.1mA and a supply current maximum of 65mA. This EPROM is manufactured to meet stringent screening levels, referencing standards such as 38535Q/M, 38534H, and 883B.
