SC16C852LIB,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C852LIB,128 is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) operating at 1.8 V with a maximum data rate of 5 Mbit/s. It features 128-byte transmit and receive FIFOs to reduce CPU bandwidth requirements. The device supports Intel (16 mode) or Motorola (68 mode) bus interfaces selectable via the 16/68 pin. It includes an IrDA encoder/decoder, modem control interface, and DMA mode data transfer. The component operates within an industrial temperature range of -40 °C to +85 °C and is housed in an LQFP48 package.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the presence of the '128' suffix indicates the specific tape and reel quantity or variant if applicable to your supply chain requirements. Ensure compatibility with 1.8 V logic levels and check for RoHS compliance documentation prior to integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a low-power 1.8 V dual UART is required with large FIFO buffers to minimize processor interrupts. It is suitable for designs needing flexible bus interface options between Intel and Motorola standards. Consider the LQFP48 package constraints and ensure the application supports the specified industrial temperature range and baud rate capabilities up to 5 Mbit/s.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C852L series serves as an enhanced successor to the SC16C652B, offering increased FIFO depth from 32 bytes to 128 bytes. It maintains pin and software compatibility with previous generations while providing advanced features like DMA support and programmable interrupt levels. This family addresses the need for efficient serial communication in modern embedded applications.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C852LIB is pin and software compatible with the SC16C652B in the LQFP48 package. Verify that any substitute component supports the same 1.8 V operation and 128-byte FIFO capacity to maintain system performance without redesign.
