2. GENERAL DESCRIPTION
MX25L51245G is 512Mb bits serial Flash memory, which is configured as 67,108,864 x 8 internally. When it is in
two or four I/O mode, the structure becomes 268,435,456 bits x 2 or 134,217,728 bits x 4. MX25L51245G feature
a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus while it is in single I/O
mode. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial
access to the device is enabled by CS# input.
When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits
input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# and RESET# pin become SIO0
pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25L51245G MXSMIO
(Serial Multi I/O) provides sequential read operation on whole chip.
After program/erase command is issued, auto program/erase algorithms which progr
