Product details

Overview

SC16IS760IBS,151 from NXP Semiconductors is a single-channel UART IC with I²C-bus or SPI slave interface, supporting up to 5 Mbit/s data rate, 64-byte TX/RX FIFOs, and IrDA SIR at 1.152 Mbit/s. It integrates 8 programmable GPIOs and operates from 2.5 V or 3.3 V in industrial temperature range (−40 °C to +95 °C), enabling protocol bridging between microcontrollers and RS-232/RS-485 peripherals in space-constrained embedded systems.

For engineers reviewing the SC16IS760IBS,151 datasheet, SC16IS760IBS,151 pinout, SC16IS760IBS,151 application, or SC16IS760IBS,151 equivalent, key selection considerations include SPI clock support up to 15 Mbit/s (vs. 4 Mbit/s on SC16IS750), IrDA SIR speed capability, HVQFN24 package thermal performance, and register compatibility with legacy 16C450 firmware.

Technical Context

The SC16IS760IBS,151 implements a full-duplex UART with backward-compatible 16C450 register mapping, enabling direct software porting. Its dual-interface architecture supports either I²C-bus (400 kbit/s, slave-only) or SPI (Mode 0, slave-only, up to 15 Mbit/s), selected via the I2C/SPI pin.

FIFO management includes independent programmable trigger levels for TX/RX interrupts (via TLR register), auto hardware flow control (RTS/CTS), and automatic RS-485 driver direction control. The device also embeds IrDA SIR encoder/decoder logic compliant with IrDA 1.152 Mbit/s physical layer, distinct from MIR mode.

Key Specifications

Interface	I²C-bus (400 kbit/s) or SPI (Mode 0, 15 Mbit/s max); interface selected by I2C/SPI pin voltage level
UART Data Rate	Up to 5 Mbit/s in 16× clock mode; enables high-speed serial communication without CPU polling overhead
FIFO Depth	64-byte transmit and receive FIFOs with programmable trigger levels; reduces host interrupt frequency and improves throughput
IrDA Support	Built-in IrDA SIR encoder/decoder supporting 1.152 Mbit/s; eliminates need for external transceiver in infrared applications

Supply Voltage	2.5 V or 3.3 V operation; supports mixed-voltage system integration with low-power sleep current (<30 µA)
Operating Temp	−40 °C to +95 °C industrial range; validated for factory automation and portable equipment environments

Pinout & Package

HVQFN24 package (SOT616-3): 4 mm × 4 mm × 0.85 mm body, thermally enhanced with exposed center pad requiring PCB ground connection for optimal thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning

8–11 GPIO4/DSR–GPIO7/RI	Modem signal I/O	Function as DSR/DTR/CD/RI when enabled in IOControl register; retain legacy modem interface compatibility
12 VSS	Ground	Primary ground reference; both corner VSS pins and center thermal pad must connect to PCB ground plane
13 VDD	Power supply	2.5 V or 3.3 V supply; decoupling capacitor required within 10 mm of pin for noise immunity
14 IRQ	Interrupt output	Open-drain active-low interrupt; requires external pull-up (1 kΩ @ 3.3 V) to indicate pending status events
15–16 CS/A0, SI/A1	SPI chip select / I²C address select	In SPI mode: CS active-low enable; in I²C mode: A0/A1 set base address (0x48–0x4F)
17 SO	SPI data output	3-stateable output; undefined in I²C mode and must remain unconnected
18 SCL/SCLK	Clock input	I²C clock (SCL) or SPI clock (SCLK); Schmitt-triggered for noise immunity
19 SDA	I²C data I/O	Open-drain bidirectional I²C bus line; must connect to VSS in SPI mode
20–21 RTS, CTS	Hardware flow control	RTS (output) and CTS (input) support auto RTS/CTS when enabled in EFR; eliminate RX FIFO overrun
22–23 TX, RX	UART serial I/O	Full-duplex TTL-level serial interface; compatible with RS-232/RS-485 transceivers via external drivers
24 I2C/SPI	Interface select	Logic HIGH selects I²C mode; LOW selects SPI mode; determines function of CS/A0, SI/A1, SDA pins

Key Features

Feature	Design Value
Auto RS-485 direction control	RTS pin automatically manages RS-485 driver enable/disable based on RX FIFO level-no external logic required
Software reset capability	UART core reset initiated via register write (EFR[7]), independent of hardware RESET pin-enables runtime recovery
Programmable character format	Supports 5–8 bit word length, even/odd/no parity, 1/1.5/2 stop bits-ensures interoperability with legacy serial devices
Independent TX/RX enable control	Transmitter and receiver can be disabled separately via Line Control Register-reduces power and prevents spurious transmission
Line break generation/detection	Generates or detects extended low-level TX pulses (>1.5 frame times)-used for system synchronization and wake-up signaling
Internal loopback mode	TX data routed internally to RX path for self-test without external cabling-validates UART functionality pre-deployment

Equivalent & Alternatives

The following parts are listed as comparable options for similar UART bridge applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SC16IS750IBS	Same HVQFN24 package and pinout; supports only 4 Mbit/s SPI and 115.2 kbit/s IrDA SIR	Lacks 1.152 Mbit/s IrDA and high-speed SPI; suitable where infrared speed is not required	Select SC16IS750IBS only if IrDA >115.2 kbit/s and SPI >4 Mbit/s are unnecessary-lower cost alternative with identical footprint
MAX3107ETJ+	Different SPI interface (Mode 3), no I²C option, 12 GPIOs, no built-in IrDA logic	Requires external IrDA transceiver; broader GPIO count but no automatic RS-485 direction control	Choose MAX3107ETJ+ when maximum GPIO flexibility is needed and IrDA is implemented externally; verify SPI mode compatibility

Compared with SC16IS750IBS and MAX3107ETJ+, the SC16IS760IBS,151 uniquely combines 15 Mbit/s SPI, 1.152 Mbit/s IrDA SIR, and automatic RS-485 direction control in a thermally optimized HVQFN24 package-making it optimal for compact, high-speed, infrared-capable industrial gateways.

FAQ

What interface modes does the SC16IS760IBS,151 support?

The SC16IS760IBS,151 supports two mutually exclusive slave interface modes: I²C-bus (up to 400 kbit/s) and SPI (Mode 0, up to 15 Mbit/s). Selection is made via the I2C/SPI pin voltage level at power-up. Both modes share identical UART register access and GPIO functionality, but pin assignments differ-SDA and SCL are used for I²C, while CS, SI, SO, and SCLK are used for SPI. The SC16IS760IBS,151 does not support master-mode operation.

How does the SC16IS760IBS,151 handle RS-485 driver direction control?

The SC16IS760IBS,151 provides automatic RS-485 driver direction control via its RTS output pin. When enabled in the Enhanced Feature Register (EFR[4]), RTS toggles based on RX FIFO occupancy-asserting LOW to enable the driver during transmission and deasserting HIGH to disable it after data is sent. This eliminates external direction-control logic and ensures precise timing alignment with UART frame boundaries, preventing bus contention in half-duplex RS-485 networks.

What is the IrDA SIR capability of the SC16IS760IBS,151?

The SC16IS760IBS,151 integrates a hardware IrDA SIR encoder/decoder supporting up to 1.152 Mbit/s, compliant with the IrDA Physical Layer specification. It processes SIR frames directly-encoding outgoing data and decoding incoming pulses-without host CPU intervention. Note that this 1.152 Mbit/s SIR mode is not compatible with IrDA MIR at the same speed; proper configuration of the IrDA control register (ICR) and use of appropriate external IR transceivers are required for reliable operation.

Can the SC16IS760IBS,151 operate from 2.5 V or 3.3 V supplies?

Yes, the SC16IS760IBS,151 is fully specified for operation from either 2.5 V or 3.3 V supplies, with corresponding internal pull-up resistor values (1.5 kΩ for 2.5 V, 1 kΩ for 3.3 V) on the IRQ pin. All I/Os-including GPIOs, UART lines, and interface pins-are 3.3 V tolerant in 2.5 V mode. The device maintains full functionality, including 5 Mbit/s UART data rate and 15 Mbit/s SPI clock, across both supply voltages, enabling flexible integration into mixed-voltage systems.

Does the SC16IS760IBS,151 support automatic hardware flow control?

Yes, the SC16IS760IBS,151 supports automatic hardware flow control using RTS and CTS signals. Auto RTS activates the RTS output when the RX FIFO has sufficient space and deactivates it when the FIFO reaches the programmed halt level (via TCR register). Auto CTS gates transmission based on CTS input state. Both features are independently enabled via EFR[6] and EFR[7], and together prevent RX FIFO overrun without host software involvement-critical for high-throughput, low-latency serial links.
