NXP Bridges NXP bridge ICs are the new generation of serial interface solutions for managing host-to-device communications among wide variety of serial bus interfaces such as I2C, SPI, and UART. Our bridges allow you to simply connect devices that use a different serial bus than your current system. These products operate at low voltages, consume little power, and come in ultra-small packaging. They are ideal for battery-operated applications.
I2C NXP A/D D/A PC SPI EE PROM SPI ASIC CPU I2CFPGA slave MCU MCU to SPI master/GPIO bridges – SC18IS602B Bridge LCD/ LED Sensor These bridges connect to an I C master port of a microcontroller or other host processor and allow you to communicate with SPI slave peripherals. The bridges have an I2C slave interface on one side and an SPI master interface on the other. The bridges can also be used to provide additional GPIO to an I2C master by utilizing unused SPI slave select outputs.
