MIKROE-6789

MIKROE-6789 is a SPI to I2C Click compact add-on board that enables communication between SPI and I2C interfaces, allowing a host microcontroller to control multiple I2C peripherals even without native I2C support. It is based on the SC18IS604, an SPI-to-I2C bridge from NXP, which manages all I2C-bus operations including protocol handling, arbitration, and timing to ensure reliable data transfer. The board operates as an SPI server supporting Mode 3 and provides a single I2C controller channel, integrating five GPIO pins, 255-byte transmit and receive buffers, and support for SPI speeds up to 1.2MHz and I2C Fast-mode up to 375kHz. It also features Deep Power-Down mode with CS wake-up, interrupt and reset pins, and onboard pull-up switches for easy configuration. SPI to I2C Click is ideal for embedded applications requiring protocol bridging, such as connecting sensors, memory devices, or peripheral modules in mixed-interface systems.
