Description: 
The SC16IS750 is a slave I2C-bus/SPI interface to a single-channel high performance UART. It offers data rates up to 5 Mbit/s and guarantees low operating and
sleeping current. The SC16IS750 and SC16IS760 also provide the application with 8 additional programmable I/O pins. The device comes in very small HVQFN24, TSSOP24 packages, which makes it ideally suitable for handheld, battery operated applications. This family of products enables seamless
protocol conversion from I2C-bus or SPI to and RS-232/RS-485 and are fully bidirectional.

The SC16IS750’s internal register set is backward-compatible with the widely used and widely popular 16C450. This allows the software to be easily written or ported from another platform.

The SC16IS750 also provides additional advanced features such as auto hardware and software flow control, automatic RS-485 support, and software reset. This
allows the software to reset the UART at any moment, independent of the hardware reset signal.

Features:
This is a breakout board for the SC16IS750, a handy chip used to convert I2C or SPI serial signals to a single-channel, high-performance UART. As an application example: we use this chip on our WiFly Shield to allow an Arduino to communicate with the WiFly RN-131G module - which is normally controlled via a UART - using an SPI interface. This allows for greater communication speeds and frees up the Arduino’s UART for other purposes.

Power applied to the ‘VIN’ pin is sent through a 3.3V LDO regulator before powering the IC. The input pins of the SC16IS750 are 5.5V tolerant, so this board should work with both 3.3V and 5V controllers. Also populated on the board is a 14.7456MHz crystal, to serve as a clock input to the chip, and other supporting components.

This board breaks out all pins of the SC16IS750 to two breadboard friendly 11-pin, 0.1" pitch headers.
