PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT)
Rev.3.0_00
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.
