TL16C554AFN General Description

The TL16C554AFN, a cutting-edge quad universal asynchronous receiver-transmitter (UART) integrated circuit crafted by Texas Instruments, stands out as an indispensable component for microcontroller-based systems seeking seamless full-duplex asynchronous communication. Boasting four independent UART channels with a remarkable baud rate of up to 5 Mbps, this IC ensures efficient data exchange. Moreover, its 16-byte FIFOs for both transmit and receive functions enhance data processing capabilities, while its compatibility with a wide array of microcontrollers and processors underscores its versatility

Key Features

Integrated Asynchronous-Communications Element
Consists of Four Improved TL16C550C ACEs Plus Steering Logic
In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU
In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data
Up to 16-MHz Clock Rate for up to 1-Mbaud Operation with VCC = 3.3 V and 5 V
Programmable Baud-Rate Generators Which Allow Division of Any Input Reference Clock by 1 to (216 – 1) and Generate an Internal 16 × Clock
Adds or Deletes Standard Asynchronous Communication Bits (Start, Stop, and Parity) to or From the Serial-Data Stream
Independently Controlled Transmit, Receive, Line Status, and Data Set Interrupts
5-V and 3.3-V Operation
Fully Programmable Serial Interface Characteristics:
- 5-, 6-, 7-, or 8-Bit Characters
- Even-, Odd-, or No-Parity Bit
- 1-, 1 1/2-, or 2-Stop Bit Generation
- Baud Generation (DC to 1-Mbit Per Second)
False Start Bit Detection
Complete Status Reporting Capabilities
Line Break Generation and Detection
Internal Diagnostic Capabilities:
- Loopback Controls for Communications Link Fault Isolation
- Break, Parity, Overrun, Framing Error Simulation
Fully Prioritized Interrupt System Controls
Modem Control Functions (RTS Mode,
