• Description: Single Chip 16 Bit Cmos Microcomputer Flash Memory Version
• Manufacturer: Mitsumi Electronics, Corp.

Flash memory mode 2 (serial I/O mode)
The M37753FFCFP and the M37753FFCHP have a function to seri-
ally input/output the software commands, addresses, and data re-
quired for operation on the internal flash memory (e. g., read,
program, and erase) using only a few pins. This is called the serial I/
O (input/output) mode. This mode can be selected by driving the
SDA (serial data input/output), SCLK (serial clock input ), and OE

In the serial I/O mode, the user can use seven types of software
commands: bank (0, 1) select, read, program, program verify, auto
erase, and error check.
Serial input/output is accomplished synchronously with the clock,
beginning from the LSB (LSB first).
