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.
