GENERAL DESCRIPTION

The MX23C4100 is a 5V only, 4M-bit, Read Only
Memory. It is organized as 512Kx8 bits (byte mode) or
as 256Kx16 bit (word mode) depending on BYTE (pin
31) voltage level. MX23C4100 has a static standby
mode, and has an access time of 100/120/150/200ns.
It is designed to be compatible with all microprocessors
and similar applications in which high performance, large
bit storage and simple interfacing are important design
considerations.

· Completely TTL compatible
· Operating current: 60mA
· Standby current: 100uA
· Package

- 40 pin DIP (600 mil)
- 40 pin SOP

PIN CONFIGURATION

40 PDIP/SOP

MX23C4100 offers automatic power-down, with power-
down controlled by the chip enable (CE) input. When
CE is not selected, the device automatically powers
down and remains in a low-power standby mode as long
as CE stays in the unselected mode.

The OE input as well as OE input may be programmed
active Low.
