PROGRAMMABLE PORT CONTROLLER
(PORT EXPANDER WITH BUILT-IN E
2PROM CIRCUIT)

The S-7750C is a programmable port controller IC comprised of an E
2PROM, 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 I
2C-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 E
2PROM.
