Microchip Technology's 27C256-12I-SO is a 32K x 8 CMOS EPROM with a 120ns maximum access time. This device features a 262144-bit memory density and operates asynchronously. Its memory organization is 32K words by 8 bits, providing a total of 32768 words. The 27C256 series component utilizes parallel I/O with 3-state outputs and a common I/O type. Designed for robust data retention exceeding 200 years, it operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 28-lead plastic small outline package (PDSO28) with gull wing terminals on a 1.27mm pitch, suitable for surface mounting. Typical applications include industrial control, automotive systems, and consumer electronics where reliable non-volatile storage is critical.
