Product Overview

CP2120EK evaluation kit demonstrates the CP2120 SPI to I2C fixed functionality. The CP2120 compact SPI to I2C bridge and general purpose port expander device can be easily added to a system to solve interface compatibility problems and add more GPIO when required. The chip includes a 4 wire slave SPI bus, bridge control logic, a bidirectional I2C bus interface and eight general purpose input/output (I/O) pins. An SPI master communicates with other I2C devices by instructing the CP2120 to send and receive I2C data traffic using the simple command set. The CP2120 can act as a master transmitter and a master receiver on the I2C bus. All I2C timing, addressing and arbitration is handled by the CP2120.
  • 4 wire SPI bus operates at frequencies up to 1MHz
  • Fully functional I2C master transmit and receive operation
  • I2C data at frequencies configurable up to 400KHz
  • 255byte data receive and transmit buffers
  • Internal oscillator
  • 2.4V to 3.6V operation
  • Active LOW interrupt output
  • 5V tolerant I/O pins
  • 8 general purpose I/O pins
