Microchip Technology's 27HC256-55I-K is a 32K x 8 (256 kilobit) CMOS EPROM with a maximum access time of 55ns. This asynchronous memory device operates from a 4.5V to 5.5V supply and features a common I/O architecture with 3-state outputs. The 27HC256 series component is housed in a 32-terminal ceramic quad flat chip carrier (CQCC32) package, suitable for surface mounting. It is designed for industrial temperature ranges, operating from -40°C to +85°C. Typical applications include industrial control systems, automotive electronics, and legacy system upgrades where reliable, non-volatile program storage is required. The component is manufactured using CMOS technology, offering low standby and active current consumption.
