Microchip Technology's 27HC256L-90I-K is a 32K x 8 CMOS EPROM with a maximum access time of 90ns. This component features a 262,144-bit memory density and operates asynchronously with 3-state outputs. The 27HC256 series part is housed in a 32-terminal Ceramic Chip Carrier (CQCC32) package, suitable for surface mounting. It operates within a supply voltage range of 4.5V to 5.5V, with a typical supply current of 55mA. Designed for reliable operation across industrial temperature ranges from -40°C to 85°C, this EPROM is utilized in applications such as industrial control systems, legacy computing, and embedded systems requiring non-volatile program storage.
