DESCRIPTION
The M27C320 is a 32 Mbit EPROM offered in the
OTP range (one time programmable). It is ideally
suited for microprocessor systems requiring large
data or program storage. It is organised 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 M27C320 is offered in TSOP48 (12 x 20mm)
and SO44 packages.
