-40 pin DIP (600 mil)

-40 pin SOP

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 power- down 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.
