SC16C850IET,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C850IET,157 is a single-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates within a voltage range of 2.5 V to 3.3 V and supports data rates up to 5 Mbit/s. The device features 128-byte transmit and receive FIFOs to reduce CPU bandwidth requirements. It includes an IrDA encoder/decoder, modem control interface, and selectable Intel or Motorola bus interfaces. The component is housed in a TFBGA36 package and functions across an industrial temperature range from -40 °C to +85 °C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and compliance status. Confirm availability as distribution channels may list discontinued or limited stock items. Ensure the selected variant matches the required bus interface mode and thermal specifications for the target application environment.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large FIFO buffers is required for low-power 2.5 V to 3.3 V systems. Consider the TFBGA36 package constraints for PCB layout. Verify compatibility with the host processor's bus interface mode, either Intel or Motorola, before integration into the design architecture.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C850 family of UART interface ICs. It serves as an upward solution to previous generations like the SC16C650B, offering increased FIFO capacity. The IET suffix specifically denotes the TFBGA36 package variant with an Intel bus interface option.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C850IBS is a functionally compatible alternative using the HVQFN32 package. Both variants share identical electrical characteristics and register sets, differing primarily in physical footprint and pin configuration.
