M27C4001 has two functions: UV (ultraviolet erasing) and OTP (one-time programmable). It is a 4 Mbit EPROM offered in December. It is ideal for microprocessor systems requiring large programs and is organized into 8-bit 524,288.
FDIP32W (window ceramic frit-seal package) and LCCC32W (lead-free chip carrier package) allow the user to It has a clear cover that allows it to expose the chip to ultraviolet light to erase the bit pattern. Then, a new pattern can be written to the device by following the programming procedure.
