GENERAL DESCRIPTION
The MX23L8051 provide sequential read operation on the DataSheet4U.
com The MX23L8051 is a CMOS 8,338,608 bit serial Mask whole chip.
ROM, which is configured as 1,048,576 x 8 internally.
The MX23L8051 features a serial peripheral interface and When the device is not in operation and CS is high, it is put software protocol allowing operation on a simple 3- wire in standby mode and draws less than 30uA DC current.
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.
