UART compatible Serial Interface Controller with receive and transmit FIFOs and support for all standard bit rates from 9600 to 921600 baud.
RS232, RS422, RS485 etc.
In some particular application, few pin count but still need chip to chip communication. This IP use one wire bi-direction (open drain) to communication. Just like UART , it is consist of one TX and one RX. User can define their own payload freedomly.
All devices are connecting through open-drain pull high bus. Every device can send data to others actively.
- Analog IC debug
- MCU program port
- Low pin count IC
