HL5310
Ultra-Low Voltage 12-bit GPIO Expander with Interrupt Output
Overview
The HL5310 is a 12-bit general purpose GPIO expander that provides remote I/O expansion for most microcontroller families via the Fast-mode Plus (Fm+) I2C-bus interface up to 1MHz. The ultra low-voltage interface allows for direct connection to a microcontroller operating down to 1.0V.
HL5310 has separate power rails (VDD_I2C, VDD_P0 and VDD_P1) for I2C bus and each 6-bit I/O ports, both ranging from 1.0V to 5.5V, allowing mixed power system where I2C bus power is not compatible with I/O port power.
HL5310 features internal power-on reset and I2C, software reset provide flexible ways to reset the IC, and four adjustable I2C slave addresses for applications.
