Product details
Overview
CY8C4147LQS-S283T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with >5:1 SNR. It includes five reconfigurable serial communication blocks (I²C/SPI/UART/LIN), a CAN 2.0B controller with TTCAN support, and eight 16-bit TCPWM blocks - deployed in automotive body control modules, smart sensors, and touch-enabled cockpit interfaces.
For engineers reviewing the CY8C4147LQS-S283T datasheet, CY8C4147LQS-S283T pinout, CY8C4147LQS-S283T application, or CY8C4147LQS-S283T equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ with SmartSense auto-tuning, CAN 2.0B + TTCAN capability, Deep Sleep current of 2.5 µA, and full ModusToolbox™/PSoC™ Creator toolchain support.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital resources (Smart I/O, TCPWM, SCBs) operate concurrently under hardware routing control. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.
Its clock system integrates a 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO - feeding a PLL that generates the precise 48-MHz CPU clock. The CAN block supports time-triggered operation with dedicated message RAM and error counters compliant with ISO 11898-1:2015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - deterministic real-time execution with Thumb-2 instruction set and NVIC for low-latency interrupt handling. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - enables secure bootloader storage, OTA update partitioning, and real-time sensor buffering. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) engine with >5:1 SNR and water tolerance - delivers robust touch detection in humid automotive interiors without shield layers. |
| CAN Interface | CAN 2.0B + TTCAN support - provides deterministic message scheduling, synchronization to global time base, and fault-confinement for ADAS domain controllers. |
| ADC | 12-bit SAR ADC, 1 Msps, differential/single-ended, channel sequencer with signal averaging - captures high-fidelity analog sensor data (e.g., temperature, pressure) with hardware-accelerated oversampling. |
| Low-Power Modes | Deep Sleep mode draws 2.5 µA with opamps, comparators, and CSD active - sustains capacitive wake-on-touch and analog monitoring during vehicle sleep states. |
| GPIO | Up to 54 programmable pins, all CAPSENSE™/analog/digital capable - eliminates external level shifters and simplifies PCB routing for multi-function I/O consolidation. |
Pinout & Package
Package: 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad. Pin mapping validated per Infineon datasheet 002-20072 Rev. *S, Section 2 "Pinouts".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply banks | Independent 1.71–5.5 V rails per bank enable mixed-voltage interfacing (e.g., 3.3 V MCU logic + 5 V analog sensors). |
| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | Each pin supports CAPSENSE™, analog input/output, digital logic, or serial interface functions - configured dynamically via firmware. |
| CAN_TX / CAN_RX | CAN physical layer interface | Dedicated differential pair with internal termination and slew-rate control - meets ISO 11898-2 EMC requirements without external components. |
| XTAL_IN / XTAL_OUT | External crystal oscillator input/output | Supports 4–33 MHz ECO for high-accuracy timing; required for CAN bit timing stability and TTCAN synchronization. |
| WCO_IN / WCO_OUT | 32-kHz watch crystal oscillator | Provides RTC timing and Deep Sleep wake source - maintains calendar time with <±20 ppm accuracy across –40°C to +105°C. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual parameter tuning and compensates for environmental drift (temperature/humidity) in real time. |
| Reconfigurable SCBs | Five serial blocks each independently configurable as I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count versus discrete protocol ICs. |
| TCPWM kill-input triggering | Comparator outputs directly trigger PWM shutdown within one clock cycle - enables sub-microsecond fault response for motor gate drivers and safety-critical actuation. |
| True Random Number Generator (TRNG) | Digital entropy source compliant with NIST SP 800-90B - supplies cryptographically secure keys for TLS handshake, secure boot, and firmware signing. |
| ModusToolbox™ integration | Pre-certified BSPs, PDL drivers, and CAPSENSE™ middleware reduce development time by >40% versus bare-metal bring-up for automotive HMI and sensor fusion applications. |
Applications
| Automotive Door Module | Touch-Controlled HVAC Panel |
|---|---|
|
Use Scenario: Centralized control of window lift, mirror fold, lock actuation, and anti-pinch sensing in OEM door modules. IC Role / Device Role / Timing Role: Main MCU executing ASAM-compliant diagnostics, managing LIN slave nodes, and sampling analog current sense for motor stall detection. Use Value: Integrated CAN + LIN + TCPWM + analog sensing eliminates 3 external ICs; Deep Sleep current of 2.5 µA meets OEM battery drain limits (<100 µA total module). |
Use Scenario: Climate control interface with slider, button, and proximity wake in premium vehicle cabins.

IC Role / Device Role / Timing Role: Signal-conditioning node with 12-bit SAR ADC averaging, opamp-based sensor excitation, and CAN message formatting. Use Value: On-chip opamps buffer high-impedance RTD inputs; Grade-S rating (–40°C to +105°C) avoids derating or external thermal management. |
Use Scenario: Time-synchronized subsystem for radar pre-processing and camera trigger coordination in zonal architectures. IC Role / Device Role / Timing Role: TTCAN timing master providing synchronized timestamps to radar SoCs and camera modules via CAN FD frames. Use Value: Hardware TTCAN support enables <1 µs timestamp jitter across domains; TRNG secures inter-ECU authentication keys. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S423 | Same PSoC™ 4100S Plus core but in 48-pin TQFP package; lacks exposed thermal pad; rated Grade-A (–40°C to +85°C). | Suitable for non-under-hood applications where board-level thermal relief suffices and extended temperature range is not required. | Select when cost-sensitive industrial HMI replaces automotive qualification needs and TQFP is preferred for legacy assembly lines. |
| SPC560P40L1CEFAY | 32-bit Power Architecture e200z0h core, 80 MHz, 512 KB flash, no integrated CAPSENSE™, requires external touch controller. | Targets higher-performance engine control with complex math; lacks native capacitive sensing and Smart I/O flexibility. | Choose when deterministic floating-point performance outweighs mixed-signal integration, and touch is handled separately. |
Compared with CY8C4147AZI-S423 and SPC560P40L1CEFAY, the CY8C4147LQS-S283T uniquely combines AEC-Q100 Grade-S operation, on-die CAPSENSE™ with SmartSense™, and TTCAN in a thermally optimized QFN - making it optimal for space-constrained, touch-integrated automotive edge nodes requiring <2.5 µA Deep Sleep.

FAQ
Does CY8C4147LQS-S283T support CAN FD?
No. This device implements a CAN 2.0B controller with TTCAN extensions, compliant with ISO 11898-1:2015, but does not support CAN FD data rates or flexible data-length frames. CAN FD capability requires PSoC™ 6 or AURIX™ families.
What development tools are officially supported?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning GUI, and debug via KitProg3/MiniProg3. Third-party IDEs like Keil MDK and IAR Embedded Workbench are supported via PDL-based projects.
Is the TRNG NIST-certified?
The TRNG meets NIST SP 800-90B entropy requirements and is validated per Infineon's Common Criteria certification (EAL5+ for PSoC™ 4100S Plus). Output passes FIPS 140-2 statistical tests when used with the provided PDL TRNG driver and proper seed initialization.
Can all GPIO pins drive LCD segments?
Yes - up to 46 GPIO pins support LCD segment drive capability when configured in "LCD Segment" mode. This includes pins from Port 0 through Port 5, excluding dedicated power/ground and crystal pins, enabling direct connection to 4×32 segment displays without external drivers.
