Function: 4 MBIT (256KB X16) UV EPROM AND OTP ROM

Package: DIP 40, PLCC 44, TSOP 40 Pin type

Manufacturer: STMicroelectronics


M27C4002 datasheet



The M27C4002 is a 4 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 262,144 words of 16 bits.
The FDIP40W (window ceramic frit-seal package) has transparent lids which allow 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.
