SUMMARY DESCRIPTION
The M27W032 is a 32 Mbit (2Mb x16) non-volatile,
One Time Programmable (OTP), FlexibleROM
Memory. Read operations can be performed using
a single low voltage (2.7 to 3.6V) supply. Program
operations require an additional V
PP
(11.4 to
12.6V) power supply. On power-up the memory
defaults to Read mode where it can be read in the
same way as a ROM or EPROM.
Program commands are written to the Command
Interface of the memory. An on-chip Program Con-
troller (PC) simplifies the process of programming
the memory by taking care of all of the special op-
erations that are required to update the memory
contents.
The M27W032 features an innovative command,
Multiple Word Program, used to program large
streams of data. It greatly reduces the total pro-
gramming time when a large number of Words are
written to the memory at any one time. Using this
command the entire memory can be programmed
in 4s, compared to 18s using the standard Word
Program.
The end of a program operation can be detected
and any error conditions identified. The command
set required to control the memory is consistent
with JEDEC standards.
Chip Enable and Output Enable signals control the
bus operation of the memory. They allow simple
connection to most microprocessors, often without
additional logic.
The memory is offered in SO44 and TSOP48 (12
x 20mm) packages. The memory is supplied with
all the bits set to ’1’.
