FEATURES
* * * * * 64K x 16 organization (JEDEC pin out) Single +5V power supply Fast access time: 120/150/200ns Totally static operation Completely TTL compatible * Operating current: 60mA * Standby current: 100uA * Package - 40 pin DIP (600 mil) - 44 pin PLCC
GENERAL DESCRIPTION
The MX23C1024 is a 5V only, 1M-bit, Read Only Memory. It is organized as 64Kx16 bit. MX23C1024 has a static standby mode, and has an access time of 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. MX23C1024 offers automatic power-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 standby mode as long as CE stays in the unselected mode. The OE input as well as CE input may be programmed active Low.

Note: Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended period may affect reliability.
