SC16IS752 I2C/SPI Bus Interface to Dual Channel UART Conversion Module, 2-Channel Serial Port Expander

Dual-channel full-duplex UART for high-performance data transmission Supports I2C or SPI interface with data rates up to 5 Mbit/s Automatic hardware flow control using RTS/CTS for reliable communication Fully compliant with industry standard 16C450 and equivalents Eight programmable I/O pins for versatile application needs and automatic RS-485 support The internal register set is backward compatible with the widely used and popular 16C450, supporting automatic hardware and software flow control, automatic RS-485 support, and software reset. The SC161S752 is an I2C/SPI bus interface connecting to a dual-channel high-performance UART, providing data rates up to 5 Mbit/s, low operating and sleep current. It provides eight additional programmable I/O pins for applications, enabling seamless protocol conversion from IC bus/SPI to RS,232/RS-485, and is fully bidirectional. The SC161S752 only supports SPI clock speeds of 4 Mbit/s, and it supports IrDA up to 1.152 Mbit/s. SIR allows software to reset the UART at any time independently of the hardware reset signal. Product Specifications: Dual-channel full-duplex UART, optional I2C bus or SPI interface, 3.3V or 2.5V operation, industrial temperature range: -40°C to +95°C, baud rates up to 5 Mbit/s in 16x clock mode, automatic RS-485 driver direction control via RTS signal, RS-485 driver direction inversion, SC161S762 supports IrDA speeds up to 1.152 kbit/s.
