DESCRIPTION

· The CP2120 is a single-chip SPI to I2C bridge and GPIO port expander.

· It features an integrated clock, eliminating the need for an external clock.

· The device includes an on-chip voltage monitor and supports SPI to I2C data transfer.

FEATURES

· Integrated clock and voltage monitor.

· SPI interface supports up to 1.0 Mbit/s transfers, configurable for LSB or MSB first.

· I2C master interface operates up to 400 kHz with 255 RX and TX data buffers.

· 8 configurable I/O pins (push-pull or open-drain), 1 edge-triggered interrupt pin, all 5V tolerant.

· Low active INT pin, operates at 2.7V to 3.6V with a typical current of 6.4 mA.

· Pb-free 20-pin QFN package.

APPLICATIONS

· Suitable for systems requiring SPI to I2C conversion.

· Ideal for expanding I/O capabilities in embedded systems.

· Not recommended for new designs.
