PROGRAMMABLE PORT CONTROLLER

(PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT)

S-7760A

Seiko Instruments Inc.

1

The S-7760A 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, controls an 8ch digital output with a serial signal.

Among the digital output ports of 8 channels, the lower 4 channels

have a timer function so that at each port, users are able to set the

default value and inverted delay time. In the higher 4 channels,

setting the fixed output is available at each port. The default value

is maintained despite power-off because this IC has an E

2PROM.

The S-7760A is able to be used to control ON/OFF for the chips

surrounding MPU and to output the default data that devices

fundamentally have.
