PROGRAMMABLE PORT CONTROLLER
(PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT)
S-7760A
The S-7760A 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, 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 E2PROM.
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.
