Datasheet MX23C4100 Datasheet (MXIC)

FEATURES

MX23C4100

4M-BIT [512K x 8/256K x 16] MASK ROM

• Switchable organization

- 512K x 8 (byte mode)

- 256K x 16 (word mode)

• Single +5V power supply

• Fast access time:100/120/150ns

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.

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

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