M27C1001-12B1

可擦除可编程ROM 1M 128Kx8 120ns

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.
