Logic Diagram DESCRIPTION The M27V400 is an 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 data or program storage.
It is organised as either 512 Kwords of 8 bit or 256 Kwords of 16 bit.
The pin-out is compatible with the most common 4 Mbit Mask ROM.
The FDIP40W (window ceramic frit-seal package) has a transparent lid which allows the user to expose the chip to ultravio...
