GENERAL DESCRIPTION

The MX23L8051 is a CMOS 8,338,608 bit serial Mask

ROM, which is configured as 1,048,576 x 8 internally. The

MX23L8051 features a serial peripheral interface and

software protocol allowing operation on a simple 3- wire

bus. The three bus signals are a clock input (SCLK), a

serial data input (SI), and a serial data output (SO). Serial

peripheral interface access to the device is enabled by CS

input.

The MX23L8051 provide sequential read operation on the

whole chip.

When the device is not in operation and CS is high, it is put

in standby mode and draws less than 30uA DC current.
