The SC18IM700IPW/S8HP from NXP Semiconductors is a UART-to-I²C bus bridge controller designed to interface the standard UART port of a microcontroller or microprocessor with I²C-bus devices. The SC18IM700 operates as an I²C-bus controller/master, handling I²C-specific protocol sequences, arbitration and timing so that the host does not need to implement the complete I²C controller function.
The UART host interface supports baud rates of up to 460.8 kbit/s with a fixed 8-N-1 format and a programmable baud-rate generator. The I²C interface supports transfer rates of up to 400 kbit/s and provides multi-master capability. Communication between the host and the SC18IM700 uses an ASCII message protocol for straightforward I²C transactions, internal-register access and GPIO control.
The device integrates eight programmable GPIO pins, a 16-byte TX FIFO and a 16-byte RX FIFO. It operates from a 2.4V to 3.6V supply, provides 5V-tolerant input capability on applicable pins, and includes a power-down mode for reduced power consumption.
The SC18IM700IPW/S8HP orderable part is supplied in a 16-pin TSSOP (SOT403-1) package with a 4.4mm body width and is rated for -40°C to +85°C operation. The /S8HP option uses 13-inch reel packaging with a listed minimum order quantity of 2500 pieces. Typical applications include I²C controller expansion, industrial control, instrumentation and embedded systems requiring UART-to-I²C connectivity.
