Rev.1.3_00 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. Features Operating voltage range: 8ch digital output: Operating frequency of I2C-bus interface: Low current consumption at standby: 2.3 to 4.5 V Higher 4 channels; fixed output/lower 4 channels; timer action 400 kHz 3.0 A Max. (VCCH = 4.5 V CMOS input type) 10.0 A Max. (VCCH = 4.5 V low voltage input type) 6-byte 105 cycles / word*1 (at 40 to +85 °C) 10 years (after rewriting 105 cycles / word) Built-in E2PROM circuit: 2 E PROM endurance: 2 E PROM data retention: Function to protect write in E2PROM Function to prevent malfunction during low power supply voltage operation Lead-free product Smal……
