MX23C4100 4M-BIT [512K x 8/256K x 16] MASK ROM FEATURES • Switchable organization - 512K x 8 (byte mode) - 256K x 16 (word mode) • Single +5V power supply • Fast access time:100/120/150ns • • • • • Totally static operation Completely TTL compatible Operating current: 60mA Standby current: 100uA Package - 40 pin DIP (600 mil) - 40 pin SOP 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 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 OE input may be programmed active Low.
