The SGM4593 is a general-purpose parallel input and output (I/O) expander device, which consists of two lanes and 8 bits parallel I/O expansion. The device communicates with processor through two-line bidirectional I2C bus (or SMBus), supporting I2C standard mode (100kHz) and I2C fast mode (400kHz) clock frequency. The SGM4593 provides a simple solution for the devices that need additional I/Os, such as LEDs, buttons, sensors, etc. The
SGM4593 can select device address by the A0, A1 and A2 pins. The SGM4593 features an interrupt generated on the nINT pin whenever the state of input port changes. An output anomaly may also be indicated by the nINT pin when the corresponding Output Anomaly Indication port register is set to 1 and the device is in push-pull output mode. The SGM4593 can cycle the power supply and cause a power-on reset to reset itself to the default state.
The SGM4593 is available in Green TSSOP-24 and TQFN-4×4-24FL packages and supports -40℃ to +125℃ temperature range.
