Description & Applications | PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2ROM CIRCUIT) 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. Features • Operating voltage range: 2.3 to 4.5 V • 8ch digital output • Operating frequency of I 2C-bus interface: 400 kHz • Function to prevent malfunction during low power supply voltage operation • Low current consumption at standby: 3.0 µA Max. (VCCH = 4.5 V) • Built-in E2PROM circuit • E2 PROM endurance: 105 cycles / word *1(at −40 to +85 °C) • E 2 PROM data retention: 10 years (after rewriting 10 5 cycles / word) • Function to protect Write in E 2PROM • Lead-free product • Small package: WLP-16A *1.
