Overview
The BR93LC56 is CMOS serial input / output-type memory circuits (EEPROMs) that can be programmed electrically.
Each is configured of 128 words
×
16 bits (2,048 bits), and each word can be accessed individually and data read
from it and written to it.
Operation control is performed using five types of commands. The commands, addresses, and data are input
through the DI pin under the control of the CS and SK pins. In a write operation, the internal status signal (READY or
BUSY) can be output from the DO pin.
The only difference between the BR93LC56 / F / RF / FV is the write disable voltage and its accompanying write
enable voltage. All other functions and characteristics are the same.
