SC16IS762IPW-T

Controllers Overview

The SC16IS762IPW-T is a dual-channel UART interface IC manufactured by NXP Semiconductors, housed in a TSSOP28 package. It provides an I2C-bus or SPI bus interface to two high-performance UART channels with data rates up to 5 Mbit/s and supports IrDA SIR speeds up to 1.152 Mbit/s. The device features 64-byte transmit and receive FIFOs for each channel, eight programmable I/O pins, and operates on 2.5 V or 3.3 V power supplies within an industrial temperature range of -40°C to +95°C. Its internal register set is backward compatible with the 16C450 standard.

Controllers Feature Summary

• Dual full-duplex UART channels with selectable I2C-bus or SPI slave interfaces
• Built-in IrDA encoder and decoder supporting SIR speeds up to 1.152 Mbit/s
• Auto hardware flow control using RTS/CTS signals and automatic RS-485 support
• Backward compatible with the widely used 16C450 industrial standard

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices requiring low power consumption
• Cellular data devices needing serial protocol conversion

Controllers Procurement Notes

Verify the specific ordering suffix '-T' against official manufacturer documentation to confirm tape-and-reel packaging status. Confirm that the TSSOP28 package variant matches the required pinout and thermal specifications for the target PCB design. Ensure compliance with current RoHS and REACH directives as indicated in the product quality information.

Controllers Selection Notes

Select this component when a system requires two independent UART ports accessible via I2C or SPI from a host microcontroller. Choose the SC16IS762 over the SC16IS752 if higher SPI clock speeds up to 15 Mbit/s or faster IrDA SIR transmission up to 1.152 Mbit/s are necessary. Consider the TSSOP28 package for applications where leaded surface-mount compatibility is preferred over the HVQFN32 option.

Controllers Part Context

This part belongs to the SC16IS7xx family of protocol bridge chips designed to expand serial communication capabilities. It functions as a slave interface, converting between parallel I2C/SPI data and serial UART streams. The family includes single-channel variants like the SC16IS750 and dual-channel versions like the SC16IS752, which shares identical electrical characteristics except for lower SPI speed limits.

Controllers Replacement Considerations

The SC16IS752IPW-T is functionally and electrically equivalent but limited to 4 Mbit/s SPI and 115.2 kbit/s IrDA. Single-channel alternatives include the SC16IS750IPW and SC16IS760IPW.
