SPI to I²C-Bus Bridge
SC18IS604 アラートの受信
SC18IS604 is designed to serve as an interface between the standard SPI of a host (microcontroller, microprocessor, chip set, etc.) and the serial I2C-bus. This allows the host to communicate directly with other I2C-bus devices. SC18IS604 can operate as an I2C-bus controller-transmitter or controller-receiver. SC18IS604 controls all the I2C-bus specific sequences, protocol, arbitration and timing.
SC18IS604 is a functional replacement for SC18IS600 with exception of: new pinout, transmit and receive buffer of 255 bytes vs 96 bytes, three instead of four GPIOs but no longer with quasi bidirectional mode, operating supply voltage lower level lowered to 1.71 V vs 2.4 V and temperature range of -40 to 105 °C vs -40 to 85 °C.
