| INDEX MX23C2048 2M-BIT [128K x 16] CMOS MASK ROM FEATURES * * * * * 128K 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 type: - 40 pin DIP (600 mil) - 44 pin PLCC GENERAL DESCRIPTION The MX23C2048 is a 5V only, 2M-bit, Read Only Memory. It is organized as 128Kx16 bit. MX23C2048 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. MX23C2048 offers automatic power-down, with powerdown controlled by the chip enable (CE/CE) input. When CE/CE is not selected, the device automatically powers down and remains in a low-power standby mode as long as CE/CE stays in the unselected mode. The OE/OE inputs as well as CE/CE input may be programmed either active High or Low.
