TL16C552FNG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C552FNG4 is a dual Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 16-byte FIFO buffer to enhance data throughput and reduce CPU intervention. The device supports asynchronous communication protocols with baud rates up to 1.8432 MHz when driven by a 18.432 MHz clock source. It operates within a supply voltage range of 3.0 V to 5.5 V and is available in a 48-lead Thin Shrink Small Outline Package (TSSOP). The component is designed for industrial temperature ranges, typically spanning from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'FNG4' against the manufacturer's current datasheet to confirm package type and lead-free compliance. Ensure the operating environment matches the specified industrial temperature range. Cross-reference the pinout diagram with the target PCB design to prevent interface mismatches during integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with FIFO buffering is required in a compact surface-mount package. Compare performance metrics such as maximum baud rate and power consumption against single-channel alternatives if only one port is needed. Verify voltage compatibility with the system logic levels before finalizing the design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C55x family of UARTs, which are widely used in embedded systems for serial data exchange. The 'TL16C552' designation indicates a dual-channel variant, while the 'FNG4' suffix specifies the 48-pin TSSOP package and RoHS-compliant construction. It serves as a direct replacement for legacy 16C552 components in modern designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-compatible replacements include the TL16C552BIPW and TL16C552CN. Verify electrical specifications and package dimensions before substitution. Alternative solutions may involve microcontrollers with built-in UART peripherals if additional processing capability is desired.
