Product Summary

The M27V322-100F1 is a 32 Mbit EPROM offered in the UV range (ultra violet erase) and OTP range. It is ideally suited for microprocessor systems requiring large data or program storage. It is organised as 2 MWords of 16 bit. The pin-out is compatible a 32 Mbit Mask ROM. The M27V322-100F1 (window ceramic frit-seal package) has a transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written rapidly to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27V322-100F1 is offered in PDIP42 package.
