SC16IS750IPW-T

Controllers Overview

The SC16IS750IPW-T is a single-channel high-performance UART featuring an I2C-bus or SPI slave interface. It operates on 2.5 V or 3.3 V power supplies with a maximum data rate of 5 Mbit/s in 16x clock mode and supports SPI clock speeds up to 4 Mbit/s. The device includes 64-byte transmit and receive FIFOs, eight programmable I/O pins, and built-in IrDA SIR support for speeds up to 115.2 kbit/s. It functions within an industrial temperature range of -40°C to +95°C and is housed in a TSSOP24 package.

Controllers Feature Summary

• Provides seamless bidirectional protocol conversion between I2C/SPI and RS-232/RS-485 interfaces.
• Features backward-compatible internal register sets with the standard 16C450 UART.
• Supports automatic hardware flow control using RTS/CTS signals and software flow control via programmable Xon/Xoff characters.
• Includes automatic RS-485 driver direction control managed by the RTS signal.

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated handheld devices
• Cellular data communication devices

Controllers Procurement Notes

Verify that the ordering suffix '-T' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets the necessary RoHS compliance standards for your manufacturing environment. Ensure the supplier provides valid traceability documentation consistent with NXP Semiconductors distribution channels.

Controllers Selection Notes

Select this model when a single UART channel with I2C or SPI connectivity is required alongside general-purpose I/O expansion. The SC16IS750 is distinct from the SC16IS740 due to its inclusion of eight programmable GPIO pins. Choose this variant over the SC16IS760 if the application does not require SPI clock speeds exceeding 4 Mbit/s or higher-speed IrDA transmission capabilities.

Controllers Part Context

This component belongs to the SC16IS7xx family of bridge ICs designed to extend serial communication capabilities in embedded systems. It serves as a slave interface allowing host processors to communicate with peripheral UART devices through standard digital buses. The family shares functional similarities but varies in channel count, GPIO availability, and maximum bus speeds.

Controllers Replacement Considerations

The SC16IS740IPW is functionally identical regarding UART operations but lacks the eight programmable I/O pins found on the SC16IS750. The SC16IS760 offers higher SPI clock speeds (up to 15 Mbit/s) and faster IrDA support but remains electrically compatible in other aspects. Verify pinout compatibility when substituting these variants.
