The XR16C854CJ is a popular integrated circuit (IC) component that belongs to the family of Universal Asynchronous Receiver/Transmitter (UART) devices. It is commonly used in embedded systems and communication applications to enable serial communication between microprocessors or microcontrollers and external devices.
Key Features of XR16C854CJ:
1. UART Functionality: The XR16C854CJ consists of four independent UART channels, each of which supports full-duplex asynchronous communications. It enables data transmission/reception and framing, with programmable baud rate generation, parity generation/checking, and modem control signals.
2. FIFO Buffers: This IC supports large First-In-First-Out (FIFO) buffers for both transmission and reception, enhancing the efficiency of data transfer. The XR16C854CJ has 64-byte transmit and receive FIFOs, which reduce the burden on the host processor, allowing it to handle other tasks efficiently.
3. 16-Bit Timer/Counter: It includes a 16-bit programmable timer/counter that can be utilized for various time-dependent applications. The timer/counter supports multiple operating modes such as frequency measurement/counting, pulse width measurement, and time interval mode.
4. Enhanced Data Rate (EDR) and Auto-Tuning: The XR16C854CJ supports Enhanced Data Rate (EDR), allowing higher communication speeds by fine-tuning the internal clock frequency
