Product details
Overview
CY8C4147LQS-S473T 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, integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning, and a CAN 2.0B block supporting TTCAN-used in vehicle body control modules for touch-enabled door handles and climate interfaces.
For engineers reviewing the CY8C4147LQS-S473T datasheet, CY8C4147LQS-S473T pinout, CY8C4147LQS-S473T application, or CY8C4147LQS-S473T equivalent, key selection criteria include its dual-mode analog capability (opamp + SAR ADC), Deep Sleep current (2.5 µA), 54 GPIO with programmable drive strength, CAN 2.0B + TTCAN compliance, and CAPSENSE™ SNR >5:1 under wet conditions.
Technical Context
This device implements a reconfigurable mixed-signal architecture where analog blocks (two opamps, 12-bit 1-Msps SAR ADC, two IDACs, two low-power comparators) and digital resources (eight TCPWM blocks, five SCBs, CAN 2.0B, Smart I/O) are routed via automatic interconnect fabric. All analog peripherals remain functional in Deep Sleep mode.
The clock system integrates multiple sources: 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO-with a PLL generating the 48-MHz CPU clock. The TRNG supports cryptographic key generation, and the CAN block includes time-triggered operation for deterministic message scheduling in safety-critical subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz-enables real-time deterministic execution of sensor fusion and motor control tasks. |
| Flash / SRAM | 128 KB flash with Read Accelerator; 16 KB SRAM-supports secure bootloader, OTA updates, and multi-threaded firmware stacks. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with signal averaging-enables high-accuracy battery voltage and temperature monitoring. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with SNR >5:1 and water tolerance-delivers reliable touch detection on wet or gloved surfaces in automotive interiors. |
| CAN Interface | CAN 2.0B with TTCAN support-provides time-synchronized messaging for chassis domain controllers and ADAS gateway functions. |
| Power Range | 1.71 V to 5.5 V supply; Deep Sleep current = 2.5 µA-enables always-on wake-on-touch functionality without draining vehicle battery. |
| GPIO Count | 54 programmable pins across QFN/TQFP packages; any pin supports CAPSENSE™, analog, or digital-reduces BOM count and PCB layer count in space-constrained ECUs. |
Pinout & Package
The CY8C4147LQS-S473T is packaged in a 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully configurable via PSoC™ Creator or ModusToolbox™; no fixed peripheral pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Four independent 1.71–5.5 V supplies enable mixed-voltage interfacing (e.g., 3.3 V MCU core + 5 V analog sensors). |
| P0[0]–P9[7] | Programmable GPIO | All 54 pins support CAPSENSE™, analog input/output, digital logic, or serial communication-no dedicated function pins required. |
| XTAL_IN/XTAL_OUT | External crystal oscillator interface | Supports 4–33 MHz ECO for precise timing in CAN and LIN communications. |
| CAN_TX/CAN_RX | Dedicated CAN transceiver interface | Hardwired to internal CAN controller; requires external transceiver (e.g., TJA1042) for physical layer compliance. |
| TRNG_IN | True random number generator seed input | Accepts external entropy source to augment internal ring oscillator-based TRNG for FIPS-compliant key generation. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning-reduces development time by >70% for touch UI certification. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain active at 2.5 µA system current-enables continuous capacitive wake detection without CPU intervention. |
| Configurable SCBs | Five serial blocks independently assignable as I²C/SPI/UART/LIN slave-allows concurrent communication with EEPROM, display driver, and diagnostic port on single die. |
| TTCAN support | Time-triggered CAN scheduling with guaranteed latency <10 µs-meets ASIL-B timing requirements for electronic parking brake control loops. |
| Programmable drive strength | GPIO output drive configurable from 2 mA to 25 mA per pin-eliminates need for external level shifters when driving LEDs or relays directly. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz; includes Ethernet MAC but no integrated CAPSENSE™ | Targeted at gateway modules requiring CAN FD + Ethernet; lacks hardware touch engine | Select when CAN FD bandwidth >1 Mbps or Ethernet bridging is required; add external touch controller for capacitive UI. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade 2 (–40°C to +105°C); no CAN FD or TTCAN | Suitable for cost-sensitive body electronics without time-triggered requirements | Choose for legacy 16-bit migration paths or where toolchain continuity with RL78 ecosystem is mandatory. |
Compared with S32K144W and RL78/F14, CY8C4147LQS-S473T uniquely combines CAPSENSE™ hardware acceleration, TTCAN, and Deep Sleep analog retention in a single 48-pin QFN-enabling compact, low-power, touch-integrated ECUs without external components.

FAQ
Is CY8C4147LQS-S473T qualified for automotive use?
Yes. It is AEC-Q100 qualified for Grade-S (–40°C to +105°C), with full qualification test reports available from Infineon. It meets HTOL, TC, ESD, and EMC requirements per AEC-Q100 Rev G, and is supported by Infineon's automotive quality management system certified to IATF 16949.
Does this part support CAN FD?
No. CY8C4147LQS-S473T integrates a CAN 2.0B controller with Time-Triggered CAN (TTCAN) support, but does not implement CAN FD protocol or higher bit rates (>1 Mbps). For CAN FD, consider Infineon's AURIX™ TC3xx family or NXP S32K3xx devices.
Can CAPSENSE™ operate reliably with water on the overlay?
Yes. Its capacitive sigma-delta (CSD) sensing architecture delivers >5:1 signal-to-noise ratio under wet conditions, and SmartSense auto-tuning dynamically adjusts baseline and thresholds to maintain false-touch immunity-validated per ISO 16750-4 for condensation and splash exposure.
What development tools are officially supported?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full CAPSENSE™ configuration, TCPWM code generation, CAN register setup, and debug via KitProg3 or MiniProg3. GitHub-hosted PDL and BSPs are updated quarterly.
