PROGRAMMABLE PORT CONTROLLER

(PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT)

S-7750C

Seiko Instruments Inc.

1

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.
