Microchip Technology's 27HC256-90I-K is a 32K x 8 CMOS EPROM featuring a 90ns access time. This component, part of the 27HC256 series, is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) package, identified by the R-CQCC-N32 JESD-30 code. Designed for asynchronous operation, it offers 3-state outputs and operates within a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement. The memory density is 262,144 bits, organized as 32,768 words by 8 bits. This device is suitable for applications in industrial control systems and legacy system upgrades requiring non-volatile program storage. The operating temperature range is -40°C to +85°C.
