SC16IS741AIPWJ

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16IS741AIPWJ is a single-channel high-performance UART featuring an I2C-bus or SPI interface. It supports data rates up to 5 Mbit/s and operates at 3.3 V or 2.5 V. The device includes 64-byte transmit and receive FIFOs, fully compatible with the 16C450 register set. It offers automatic hardware and software flow control, IrDA SIR support, and software reset capabilities. Operating temperatures range from -40 °C to +95 °C in the TSSOP16 package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Backward-compatible internal register set with the widely used 16C450 standard for easy software porting.
• Supports seamless bidirectional protocol conversion between I2C/SPI interfaces and RS-232/RS-485 serial lines.
• Includes built-in IrDA encoder and decoder interface along with automatic RS-485 driver direction control via RTS signal.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Factory automation and process control
• Portable and battery operated devices
• Cellular data devices

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix J indicates reel packing method Q1/T1 with a minimum order quantity of 2500 units. Confirm the temperature grade matches industrial requirements (-40 °C to +95 °C) and voltage operation (3.3 V ± 0.3 V). Ensure the TSSOP16 package type aligns with PCB layout constraints before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a low-power UART with I2C or SPI connectivity is required for battery-operated handheld applications. The backward compatibility with 16C450 simplifies migration from legacy systems. Consider the 64-byte FIFO depth for reducing host processor overhead during high-speed data transfers up to 5 Mbit/s.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16IS741AIPWJ belongs to the SC16IS741A family of single-channel UARTs manufactured by NXP Semiconductors. This series is designed to bridge parallel bus architectures like I2C and SPI to asynchronous serial communication standards. The IPW variant specifically denotes the TSSOP16 plastic thin shrink small outline package configuration.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16IS741AIPW is the base part number for this component. Verify if the 'J' suffix strictly affects packaging rather than electrical characteristics. No other direct substitute part numbers are documented in the provided datasheet.

UARTs (Universal Asynchronous Receiver Transmitter) FAQ

How does the SC16IS741A handle hardware flow control?

It utilizes auto RTS and auto CTS functions controlled via the Enhanced Feature Register (EFR). Auto RTS activates when the RX FIFO has space, while auto CCTS checks the CTS pin state before transmitting data.

What reset methods are supported by the device?

The device supports hardware reset, Power-On Reset (POR), and software reset. All three methods reset internal registers identically, except for DLL, DLH, SPR, XON1, XON2, XOFF1, and XOFF2 which retain their values.

Can the transmitter and receiver be controlled independently?

Yes, the transmitter and receiver can be enabled or disabled independently of each other using the appropriate control registers.
