Product details
Overview
SC16IS760IPW-T from NXP Semiconductors is a single-channel, high-performance UART with I²C-bus or SPI slave interface, supporting up to 5 Mbit/s data rates, 64-byte TX/RX FIFOs, and IrDA SIR up to 1.152 Mbit/s. It integrates 8 programmable GPIOs and operates from 2.5 V or 3.3 V across −40 °C to +95 °C, enabling protocol bridging between microcontrollers and RS-232/RS-485 peripherals in space-constrained industrial systems.
For engineers reviewing the SC16IS760IPW-T datasheet, SC16IS760IPW-T pinout, SC16IS760IPW-T application, or SC16IS760IPW-T equivalent, key selection criteria include SPI clock speed (15 Mbit/s), IrDA SIR capability (1.152 Mbit/s), GPIO count (8), FIFO depth (64 bytes), and TSSOP24 package compatibility with legacy 16C450 register mapping.
Technical Context
The SC16IS760IPW-T implements a fully programmable UART core with backward-compatible 16C450 register set, supporting both I²C (up to 400 kbit/s) and SPI (up to 15 Mbit/s, Mode 0) interfaces. Its dual-mode flow control includes auto RTS/CTS hardware handshaking and Xon/Xoff software flow control with dual-character support.
It features automatic RS-485 driver direction control via RTS, built-in IrDA encoder/decoder, and independent enable/disable control of transmitter and receiver. Sleep current is <30 µA at 3.3 V, and internal loopback mode supports diagnostics without external cabling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interface | I²C-bus (400 kbit/s) or SPI (15 Mbit/s, Mode 0) - selectable via I2C/SPI pin; no host-side protocol conversion logic required |
| UART Data Rate | Up to 5 Mbit/s in 16× clock mode - enables high-speed serial links without oversampling limitations |
| FIFO Depth | 64-byte transmit and receive FIFOs - reduces CPU interrupt load and prevents overrun under burst traffic |
| IrDA Support | IrDA SIR up to 1.152 Mbit/s - enables infrared communication without external encoder/decoder ICs |
| GPIO Pins | 8 programmable I/O pins (GPIO0–GPIO7) - configurable as general-purpose I/O or modem control signals (DSR/DTR/CD/RI) |
| Operating Voltage | 2.5 V or 3.3 V - compatible with modern low-voltage MCU domains and battery-powered designs |
| Temperature Range | −40 °C to +95 °C - qualified for industrial automation and factory floor deployment |
Pinout & Package
TSSOP24 package (SOT355-1): plastic thin shrink small outline, 24 leads, 4.4 mm body width; exposed pad not present - standard PCB assembly with no thermal pad requirement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | 2.5 V or 3.3 V main supply; decoupling capacitor required per datasheet layout guidelines |
| VSS | Ground | Digital ground reference; must be connected to system GND plane with low-inductance path |
| XTAL1 / XTAL2 | Clock input/output | Supports crystal oscillator (1–25 MHz) or external clock source; determines UART baud rate accuracy |
| TX / RX | UART serial I/O | Full-duplex asynchronous transmit/receive; level-shifted to match RS-232/RS-485 transceiver inputs |
| RTS / CTS | Hardware flow control | Active-low signals; auto-controlled by UART when EFR[6:7] enabled - eliminates software polling overhead |
| IRQ | Interrupt output | Open-drain, active-low; asserts on FIFO threshold, line error, modem status change, or Xoff detection |
| I2C/SPI | Interface select | Logic HIGH = I²C mode; LOW = SPI mode - sets internal bus controller configuration at power-up |
| GPIO0–GPIO7 | Programmable I/O | Configurable as inputs/outputs or modem control functions (DSR/DTR/CD/RI); individually controllable via IOControl register |
Key Features
| Feature | Design Value |
|---|---|
| 16C450 register compatibility | Enables drop-in software porting from legacy platforms without driver rewrite or register remapping |
| Auto RS-485 direction control | RTS signal automatically manages transceiver DE/RE pins - eliminates external logic or timing-critical GPIO toggling |
| Programmable FIFO trigger levels | Independent RX/TX interrupt thresholds via TLR register - optimizes interrupt frequency vs. latency trade-off |
| Software reset capability | UART core reset initiated via register write - avoids board-level reset assertion and preserves host state |
| Low-power sleep mode | <30 µA quiescent current at 3.3 V - extends battery life in portable instrumentation and handheld terminals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar UART bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SC16IS750IPW | Max SPI clock 4 Mbit/s; IrDA SIR limited to 115.2 kbit/s; identical pinout and register map | Suitable for lower-speed embedded control where 15 Mbit/s SPI or 1.152 Mbit/s IrDA is unnecessary | Select SC16IS750IPW only if SPI bandwidth and IrDA speed requirements are relaxed - no PCB change needed |
| MAX3107ETJ+ | 3.3 V only; SPI-only interface; no IrDA support; 128-byte FIFO; different register structure | Better suited for high-FIFO-depth, SPI-centric designs without infrared or dual-interface flexibility | Choose MAX3107ETJ+ when maximizing FIFO capacity and minimizing software porting effort outweighs need for IrDA or I²C compatibility |
Compared with SC16IS750IPW, the SC16IS760IPW-T delivers 3.75× higher SPI throughput and 10× faster IrDA SIR - critical for real-time telemetry aggregation. Against MAX3107ETJ+, it trades FIFO depth for protocol flexibility and infrared capability, simplifying system architecture in mixed-interface deployments.

FAQ
What interface protocols does the SC16IS760IPW-T support?
The SC16IS760IPW-T supports both I²C-bus (up to 400 kbit/s) and SPI (up to 15 Mbit/s, Mode 0) as slave interfaces. Interface selection is controlled by the I2C/SPI pin: HIGH selects I²C, LOW selects SPI. The SC16IS760IPW-T does not support master-mode operation on either bus, and its register map remains identical regardless of selected interface.
Does the SC16IS760IPW-T support IrDA communication, and at what speed?
Yes, the SC16IS760IPW-T includes built-in IrDA encoder and decoder circuitry supporting SIR (Serial Infrared) at up to 1.152 Mbit/s. This is a distinguishing feature versus the SC16IS750IPW-T (115.2 kbit/s max). The SC16IS760IPW-T handles all IrDA framing, pulse shaping, and timing internally - no external components are required for compliant SIR operation.
How many GPIO pins does the SC16IS760IPW-T provide, and what are their functions?
The SC16IS760IPW-T provides eight programmable GPIO pins (GPIO0 through GPIO7), accessible in TSSOP24 and HVQFN24 packages. Each can be configured as general-purpose input/output or assigned to modem control functions: GPIO4/DSR, GPIO5/DTR, GPIO6/CD, and GPIO7/RI. Configuration is performed via the IOControl register, and direction is set per-pin.
What is the FIFO depth of the SC16IS760IPW-T, and how is it managed?
The SC16IS760IPW-T features independent 64-byte transmit and receive FIFOs. FIFO operation is enabled via the FIFO Control Register (FCR), and trigger levels for interrupt generation are programmable via the Trigger Level Register (TLR) or selectable via FCR bits. Both FIFOs retain error status (for RX) and support automatic hardware/software flow control integration.
Is the SC16IS760IPW-T pin-compatible with other devices in the SC16IS7xx family?
Yes, the SC16IS760IPW-T shares identical pinout and register mapping with the SC16IS750IPW in TSSOP24 and HVQFN24 packages. It is not pin-compatible with the SC16IS740IPW (TSSOP16, no GPIOs). All three variants maintain 16C450 register compatibility, enabling software reuse - but only SC16IS760IPW-T supports 15 Mbit/s SPI and 1.152 Mbit/s IrDA SIR.
