SC16C852LIBS,115

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C852LIBS,115 is a low-power, dual-channel Universal Asynchronous Receiver and Transmitter (UART) operating at 1.8 V. It supports serial data rates up to 5 Mbit/s and features 128-byte transmit and receive FIFOs to reduce external CPU bandwidth requirements. The device includes an IrDA encoder/decoder, modem control interface, and DMA mode data transfer capabilities. It offers selectable Intel or Motorola bus interfaces via the 16/68 pin and operates within an industrial temperature range of -40 °C to +85 °C. The component is housed in a plastic thermal enhanced very thin quad flat package with no leads, specifically HVQFN32.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a 1.8 V dual UART with large FIFO buffers is required. Ensure the host system supports either Intel or Motorola bus modes. Verify that the HVQFN32 package fits the PCB layout constraints. Confirm compatibility with existing firmware designed for SC16C652B if migrating from previous generations.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C852L series serves as an upward solution to the SC16C652B, offering increased performance through larger FIFO memory. It is part of NXP's low-power UART portfolio designed for mobile and embedded applications. The LIBS variant specifically denotes the HVQFN32 package option within the broader SC16C852L family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C852LIBS is pin, function, and software compatible with the SC16C652B in the LQFP48 package. However, direct replacement requires accounting for the package difference between HVQFN32 and LQFP48. No other direct substitutes are documented.
