DESCRIPTION
The M27C405 is a 4 Mbit EPROM offered in the
OTP (one time programmable) range. It is ideally
suited for microprocessor systems requiring large
programs, in the application where the contents is
stable and needs to be programmed only one time
and is organised as 524,288 by 8 bits.
The M27C405 is pin compatible with the industry
standard 4 Mbit, single voltage Flash memory. It
can be consideredas a Flash Low Cost solution for
production quantities.
The M27C405 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.
