TL16C2550RHBR General Description

Elevate your serial communication capabilities with the TL16C2550RHBR, a dual UART that combines the functionality of two TL16C550D UARTs in a single device. Each ACE within the TL16C2550RHBR operates independently, with separate register sets and FIFOs for optimal performance. The device offers a 16-byte FIFO buffer for both receiving and transmitting data, along with a programmable baud rate generator for flexible data rate control. With advanced features like autoflow control and modem control capability, the TL16C2550RHBR streamlines data flow and enhances system efficiency. Whether you require high-speed serial communication or robust data buffering, the TL16C2550RHBR delivers unmatched performance and versatility
