Key Features
- Dual independent UART channels each with 16-byte transmit and receive FIFOs to reduce CPU interrupt overhead in high-throughput serial communication
- Wide supply voltage range operating down to 1.8V minimum at 10 MHz, enabling low-power embedded and battery-operated designs
- Maximum clock frequency of 24 MHz supporting baud rates up to 1.5 Mbps for high-speed asynchronous serial data transfer
- 8-bit parallel host interface with 3-bit address bus for straightforward integration with microprocessors and embedded SoC peripherals
Applications
The TL16C2550IPFBG4 is used in embedded systems requiring two independent UART channels for simultaneous communication with peripherals such as GPS modules, modems, barcode readers, and wireless transceivers. Its 16-byte FIFO buffers make it well-suited for high-throughput data acquisition systems and industrial controllers where CPU interrupt latency must be minimized. The 1.8V minimum supply compatibility also makes it suitable for integration into modern low-voltage microprocessor systems and portable instruments.

Frequently Asked Questions
How many UART channels does the TL16C2550IPFBG4 provide?
The TL16C2550IPFBG4 provides two independent fully functional UART channels, each with its own 16-byte transmit FIFO and 16-byte receive FIFO. This allows simultaneous asynchronous serial communication on two separate ports, reducing the need for multiple discrete UART devices.
What is the maximum baud rate supported by the TL16C2550IPFBG4?
With a maximum clock frequency of 24 MHz and a standard 16x clock divider, the TL16C2550IPFBG4 supports baud rates up to 1.5 Mbps. Lower baud rates from 300 bps up to 1.5 Mbps are achievable by programming the divisor latch registers.
What is the minimum supply voltage for the TL16C2550IPFBG4?
The TL16C2550IPFBG4 can operate at a minimum supply voltage of 1.8V at a clock frequency of 10 MHz, making it compatible with modern low-voltage microprocessors and SoCs. At higher supply voltages up to 5V, the device operates at the full 24 MHz clock rate.
What package does the TL16C2550IPFBG4 come in?
The TL16C2550IPFBG4 is housed in a 48-pin Plastic Quad Flat Package (PQFP), designated by JESD-30 code S-PQFP-G48. This surface-mount package provides a compact footprint suitable for space-constrained PCB designs in industrial and embedded computing applications.
What communication protocol does the TL16C2550IPFBG4 support?
The TL16C2550IPFBG4 implements asynchronous serial communication (UART) using bit-serial asynchronous framing compatible with RS-232, RS-485, and other serial standards. It supports standard UART features including programmable character length (5 to 8 bits), stop bits (1 or 2), and parity (odd, even, or none).
