| INDEX MX23C2100 2M-BIT [256K x 8/128K x 16] CMOS MASK ROM FEATURES * Switchable organization - 256K x 8 (byte mode) - 128K x 16 (word mode) * Single +5V power supply * Fast access time:150/200ns * Totally static operation * * * * Completely TTL compatible Operating current: 60mA Standby current: 100uA Package type: - 40 pin DIP (600 mil) GENERAL DESCRIPTION The MX23C2100 is a 5V only, 2M-bit, Read Only Memory. It is organized as 256K x 8 bits (byte mode) or as 128K x 16 bit (word mode) depending on BYTE (pin 31) voltage level. MX23C2100 has a static standby mode, and has an access time of 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. MX23C2100 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.
