PROGRAMMABLE PORT CONTROLLER
(PORT EXPANDER WITH BUILT-IN E²PROM CIRCUIT)
S-7750C
„ Features
The S-7750C is a programmable port controller IC comprised of an
E²PROM, a control circuit for data output, a circuit to prevent
malfunction caused by low power supply voltage and others.
This IC operates at 400 kHz and interfaces with exteriors via
I²C-bus. Using a serial signal, users can control both of the 8ch
digital output “H” or “L” and delay time which can be set at each
channel.
For the digital output pins at the 8 channels, the default value and
inverted delay time are settable at each port. This IC is effective to
control ON / OFF the chips surrounding MPU. And this IC
maintains the default value for control despite power-off due to the
included E²PROM.
