Summary description
The M27C1001 is a 1 Mbit EPROM offered in the two ranges: UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large programs and is organized as 131,072 words of 8 bits.
The FDIP32W (window ceramic frit-seal package) has a transparent lid that enables the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure.
