Microchip Technology's 27HC256 is a 32K x 8 bit CMOS Electrically Programmable Read-Only Memory (EPROM) featuring a maximum access time of 55ns. This component is organized as 32,768 words, each 8 bits wide, providing a total memory density of 262,144 bits. It operates with a common I/O and 3-state output characteristics, suitable for asynchronous read operations. The device is housed in a 28-pin CERAMIC, GLASS-SEALED Dual In-line Package (CDIP28) with through-hole mounting. The operating temperature range is from -40°C to +85°C, and it requires a supply voltage between 4.5V and 5.5V. This EPROM finds application in various industrial and commercial systems requiring non-volatile data storage, such as legacy control systems and embedded applications. The 27HC256 offers reliable performance for designs demanding robust memory solutions.
