2PCS SC16IS752 IIC I2C/SPI Bus Interface to Dual Channel UART Conversion Board Module

Product description 2PCS SC16IS752 IIC I2C/SPI Bus Interface to Dual Channel UART Conversion Board Module The SC16IS752 is an I2C bus/SPI bus interface that connects to a dual-channel, high-performance UART, providing data rates up to 5 Mbit/s, low operating and sleep currents, and eight additional programmable I/O pins for the application. Seamless protocol conversion from I2C bus/SPI to RS-232/RS-485, and fully bidirectional. The SC16IS752 only supports SPI clock speeds of 4 Mbit/s and it supports IrDA SIR up to 1.152 Mbit/s. The internal register set is backward compatible with the widely used and popular 16C450.

Supports automatic hardware and software flow control, automatic RS-485 support, and software reset. Allows the software to reset the UART at any time, independent of the hardware reset signal. Dual Full-Duplex UART Optional I2C bus or SPI interface 3.3 V or 2.5 V operation
Industrial temperature range: -40 °C to +95 °C Fully compatible with industry standard 16C450 and equivalent Baud rate up to 5 Mbit/s in 16× clock mode Automatic hardware flow control using RTS/CTS Automatic RS-485 support (automatic slave address detection) Up to eight programmable I/O pins RS-485 driver direction control via RTS signal RS-485 driver direction control reversal SC16IS762 supports IrDA SIR up to 1.152 kbit/s Software reset Enable/disable transmitters and receivers independently of each other Programmable special character detection, fully programmable character format 5-bit, 6-bit, 7-bit or 8-bit characters, even, odd or no parity, 1, 112 or 2 stop bits Line stop generation and detection Internal loopback mode Sleep current below 3.3 at 3.3 V 5 V tolerance input Built-in IrDA encoder and decoder support IrDA SIR up to 115.2 kbit/s Automatic software flow control with programmable Xon/Xoff characters, single or two Xon/Xoff characters 64-byte FIFO (transmitter and receiver), receive and transmit FIFO levels SPI Bus Function SC16IS752 supports SPI clock speeds of up to 4 Mbit/s Slave mode only SPI mode 0
