Description & Applications | PROGRAMMABLE PORT CONTROLLER (PORT EXPANDER WITH BUILT-IN E2PROM CIRCUIT) The S-7750C 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. 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 E2PROM. 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 E2PROM • Lead-free product • Small package: WLP-16A *1.
