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 SO44 and TSOP48

(12 x 20 mm) packages.
