TL16PIR552PH

Overview

The TL16PIR552PH is a dual universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce processor intervention. The device supports selectable IrDA modes and includes a parallel port compatible with IEEE 1284 standards. Designed for surface-mount applications, it utilizes an 80-pin PQFP package. The component operates on a typical supply voltage of 5 V and functions within a temperature range of -40 °C to +85 °C, supporting data rates up to 1 MBd.

Feature Summary

• Dual UART architecture with independent channel operation
• Integrated 16-byte FIFO buffers for both transmission and reception
• Selectable IrDA communication modes
• Parallel port functionality compliant with IEEE 1284 standard

Applications

• Industrial control systems requiring serial communication
• Embedded systems with printer interface requirements
• Data acquisition modules utilizing parallel port connectivity
• Communication equipment needing high-speed serial data transfer

Procurement Notes

Verify the specific ordering suffix 'PH' corresponds to the 80-pin PQFP tray packaging configuration as documented in official Texas Instruments datasheets. Confirm that the device meets all required environmental specifications for the intended operating temperature range. Ensure compatibility with system voltage levels and signal integrity requirements before integration into final designs.

Selection Notes

Select this component when dual serial ports and parallel interface capabilities are required in a single package. The built-in FIFOs make it suitable for applications demanding efficient data handling without excessive CPU overhead. Consider the 80-pin footprint and thermal characteristics during PCB layout planning to ensure reliable operation under specified electrical and environmental conditions.

Part Context

This part belongs to the TL16C552 family of UART controllers from Texas Instruments. It extends the functionality of standard UARTs by adding IrDA support and a parallel port interface. The device is designed for use in microcontroller-based systems where multiple communication interfaces are necessary, providing a compact solution for complex I/O requirements in embedded applications.

Replacement Considerations

The TL16C552AIFN is a related dual UART component but differs in package type (PLCC-68 vs. PQFP-80) and lacks the integrated parallel port feature. Verify pinout compatibility and functional equivalence before substitution. Other family members may offer similar UART capabilities but require validation of specific interface extensions and physical dimensions.
