GENERAL DESCRIPTION
The MX23L1651 is a CMOS 16,777,216 bit serial Mask
ROM, which is configured as 2,097,152 x 8 internally. The
MX23L1651 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 MX23L1651 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.
