SC16C852LIBS,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C852LIBS,151 is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) operating at 1.8 V with data rates up to 5 Mbit/s. It features 128-byte transmit and receive FIFOs, selectable Intel (16 mode) or Motorola (68 mode) bus interfaces, and IrDA encoder/decoder support. The device includes hardware flow control, modem control signals, and an internal loopback capability for diagnostics. It operates within an industrial temperature range of -40 °C to +85 °C and is housed in an HVQFN32 package.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against NXP documentation to confirm package type and environmental compliance. Confirm availability status as components may be discontinued. Ensure the selected variant matches the required bus interface mode and package dimensions for your PCB design.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a low-voltage dual UART with large FIFO buffers is required. Consider the HVQFN32 package constraints and thermal requirements. Verify compatibility with the host processor's bus interface mode (Intel vs. Motorola). Ensure the system clock supports the desired baud rate generation capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C852L series provides enhanced UART functionality compared to previous generations like the SC16C652B. It offers increased FIFO depth and additional programmable trigger levels for improved throughput. The device maintains software compatibility with earlier models while adding advanced features like IrDA and flexible flow control.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C852L is pin compatible with the SC16C652B in LQFP48 packages. For direct replacements, verify that the substitute part supports the same voltage levels, FIFO sizes, and bus interface modes. Check for any differences in register mapping or feature sets that might require firmware adjustments.
