DESCRIPTION
The M27V320 is a low voltage 32 Mbit EPROM of-
fered in the OTP range (one time programmable).
It is ideally suited for microprocessor systems re-
quiring large data or program storage. It is organ-
ised as either 4 MWords of 8 bit or 2 MWords of 16
bit. The pin-out is compatible with the 32 Mbit
Mask ROM.
The M27V320 is offered in SO44 and TSOP48
(12 x 20 mm) packages.
