SC16C850IET,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C850IET,151 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 serial data rates up to 5 Mbit/s. The device features 128-byte transmit and receive FIFOs with programmable interrupt trigger levels. It includes an integrated IrDA encoder/decoder supporting version 1.0 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 ',151' against official NXP documentation to confirm tape and reel packaging details. Confirm that the TFBGA36 package variant matches the required board layout specifications. Ensure compatibility with the intended host processor's bus interface mode selection logic before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with large buffer capacity is required for low-voltage applications. The TFBGA36 package is suitable for space-constrained designs. Verify that the host system can support the necessary clock frequencies for baud rate generation and that the operating voltage aligns with the 2.5 V to 3.3 V specification.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C850 serves as an enhanced successor to the SC16C650B, offering increased FIFO depth. While the SC16C650B provides 32-byte FIFOs, the SC16C850 expands this to 128 bytes, significantly improving throughput in multi-channel environments. It maintains software compatibility with previous generations while adding advanced flow control and diagnostic features.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C850IBS offers identical functionality but utilizes an HVQFN32 package instead of TFBGA36. For legacy compatibility, the SC16C650B is functionally similar but limited to 32-byte FIFOs. Ensure pinout differences are accounted for if substituting between package types.
