Additional Details

The CY27C256A-150JC operates from a single 5V power supply and features TTL-compatible inputs and outputs. It is housed in a JEDEC-approved package for easy integration into standard memory sockets. The device is erased by exposure to ultraviolet light through a transparent window on the package. The erased state is typically all logic ones. New data can then be programmed into the device using standard EPROM programming techniques.
