SC18IM704PWJ Description

Short technical summary and product information.

The SC18IM704PWJ from NXP Semiconductors is a versatile UART to I2C-bus bridge controller. It enables microcontrollers and microprocessors to communicate directly with I2C-bus devices by handling all I2C-specific sequences, protocol, arbitration, and timing.

 

Key features include a UART host interface, I2C-bus controller functionality, and eight programmable I/O pins. It supports high-speed UART up to 460.8 kbit/s and Fast-mode I2C-bus at 375 kHz. The device operates from a supply voltage of 1.71V to 3.6V and consumes a current of 4mA. It includes a 256-byte TX FIFO and a 256-byte RX FIFO for efficient data buffering.

 

Designed for industrial control, medical equipment, and handheld computers, the SC18IM704PWJ operates within a temperature range of -40°C to 105°C. It is available in a 16-TSSOP package with a body width of 4.4 mm and a pitch of 0.65 mm. The input pins feature 5V tolerance, and ESD protection exceeds 2000V HBM.

 

This device simplifies the integration of I2C-bus capabilities into systems that primarily use a UART interface. Its ASCII message protocol makes control sequences straightforward for the host microcontroller.
