Product details
Overview
CY8C4147LQSS255XQSA1 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 a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks-used in motor control, touch HMI, and body electronics systems.
For engineers reviewing the CY8C4147LQSS255XQSA1 datasheet, CY8C4147LQSS255XQSA1 pinout, CY8C4147LQSS255XQSA1 application, or CY8C4147LQSS255XQSA1 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAN 2.0B with time-triggered capability, Deep Sleep current of 2.5 µA, programmable analog (opamps, 12-bit SAR ADC, IDACs), and CAPSENSE™ hardware acceleration with SmartSense auto-tuning.
Technical Context
This device implements a mixed-signal SoC architecture where the Arm® Cortex®-M0+ core manages firmware execution while dedicated hardware blocks handle real-time analog acquisition (12-bit 1-Msps SAR ADC), capacitive sensing (CSD engine with sigma-delta modulation), and deterministic communication (CAN 2.0B with TTCAN timing compliance). The clock system integrates ECO (4–33 MHz), WCO (32 kHz), IMO (±2%), and ILO for flexible low-power operation.
Digital subsystems include eight TCPWM blocks supporting center-aligned PWM and quadrature decoding, five SCBs enabling concurrent I²C/SPI/UART/LIN, and Smart I/O logic for Boolean port-level signal conditioning without CPU intervention-enabling deterministic response in safety-critical automotive functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with Thumb-2 instruction set and NVIC-based interrupt handling. |
| Flash / SRAM | 128 KB flash with Read Accelerator / 16 KB SRAM - supports complex automotive firmware with fast code fetch and data buffering for sensor fusion. |
| Operating Voltage | 1.71 V to 5.5 V - accommodates wide automotive battery rail variation including cold-crank (≤2.2 V) and load-dump (≥5 V) conditions. |
| Deep Sleep Current | 2.5 µA digital system current - sustains wake-on-CAN or CAPSENSE™ event detection while minimizing quiescent power in always-on modules. |
| CAN Interface | CAN 2.0B with TTCAN support - provides time-triggered scheduling for synchronized actuator control in chassis and powertrain networks. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures robust touch button/slider operation under wet or noisy EMI environments (e.g., infotainment panels). |
| GPIO Count | Up to 54 programmable pins - allows direct connection of sensors, actuators, LEDs, and LCD segments without external glue logic. |
Pinout & Package
The CY8C4147LQSS255XQSA1 is housed in a 64-pin TQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully configurable via PSoC™ Creator or ModusToolbox™; all GPIOs support CAPSENSE™, analog input/output, or digital logic roles with programmable drive strength and slew rate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O Power Supply | Independent 1.71–5.5 V domains per port group - enables mixed-voltage interfacing (e.g., 3.3 V MCU logic with 5 V sensor outputs). |
| VDDD / VDDA | Digital / Analog Core Supply | Separate regulated supplies reduce noise coupling between digital switching and precision analog acquisition paths. |
| XTAL_IN / XTAL_OUT | External Crystal Oscillator Input/Output | Supports 4–33 MHz crystal for high-accuracy timing; required for CAN bit-rate stability and ECU synchronization. |
| CAN_TX / CAN_RX | CAN Bus Transceiver Interface | Dedicated differential pins with internal termination and slew control - meet ISO 11898-2 physical layer requirements without external transceiver components. |
| SWDCLK / SWDIO | ARM Serial Wire Debug Interface | Two-pin debug interface supporting full-speed programming, breakpointing, and real-time trace - essential for automotive functional safety validation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CAPSENSE™ CSD Engine | Hardware-accelerated capacitive sensing with automatic SmartSense tuning - eliminates manual calibration and reduces firmware overhead for multi-button HMI designs. |
| Programmable Analog Blocks | Two opamps (with comparator mode), 12-bit SAR ADC, two IDACs - enable sensor signal conditioning, current sourcing for RTD/thermistor bias, and analog front-end integration without external ICs. |
| Time-Triggered CAN (TTCAN) | Hardware-supported deterministic CAN scheduling - ensures predictable message transmission windows for ASIL-B compliant control loops (e.g., electronic parking brake). |
| Low-Power Deep Sleep Mode | 2.5 µA system current with active analog comparators and CAPSENSE™ wakeup - extends battery life in always-on vehicle access modules and telematics units. |
| Reconfigurable SCBs | Five independent serial blocks supporting I²C/SPI/UART/LIN in any combination - simplifies communication topology design across multiple ECUs without pin remapping or hardware changes. |

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™; requires external touch controller. | Better suited for gateway or ADAS-adjacent nodes requiring floating-point math and network connectivity. | Select when higher compute throughput or Ethernet is required; avoid if CAPSENSE™ integration and cost-sensitive HMI are priorities. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz; AEC-Q100 Grade-2 (–40°C to +105°C); no CAN FD or TTCAN; limited analog resources (10-bit ADC, no IDACs). | Targeted at simpler body electronics with basic LIN/I²C and minimal touch requirements. | Select for legacy-compatible, low-cost replacements where advanced CAPSENSE™ or deterministic CAN is not needed. |
Compared with NXP S32K144W and Renesas RL78/F14, CY8C4147LQSS255XQSA1 uniquely combines AEC-Q100 Grade-S qualification, hardware CAPSENSE™, TTCAN, and programmable analog in a single 64-pin TQFP - making it optimal for cost-constrained, touch-enabled automotive ECUs requiring deterministic timing and low-power always-on capability.

FAQ
Is CY8C4147LQSS255XQSA1 qualified for automotive use?
Yes. This device is AEC-Q100 qualified to Grade-S (–40°C to +105°C), with full documentation including stress test reports, failure analysis summaries, and qualification certificates available through Infineon's official product page and authorized distributors. It meets automotive reliability, ESD, and thermal cycling requirements for body electronics and cabin control applications.
Does CY8C4147LQSS255XQSA1 support CAN FD?
No. It implements CAN 2.0B with time-triggered capability (TTCAN), but does not support CAN FD data rates or extended frame formats. For CAN FD requirements, consider Infineon's newer AURIX™ TC3xx family or cross-evaluate NXP S32K3xx devices with native CAN FD support.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ hardware can remain active in Deep Sleep mode with 2.5 µA total system current, detecting touch events and waking the CPU via interrupt. SmartSense auto-tuning operates during active mode only; baseline tracking continues in Deep Sleep using internal low-power comparators and CSD engine clocks derived from ILO.
What development tools are supported for firmware creation?
Infineon officially supports PSoC™ Creator (Windows-only IDE with schematic-based design) and ModusToolbox™ (cross-platform, Eclipse-based, CLI-capable). Both provide CAPSENSE™ configuration tools, peripheral drivers (PDL), and BSPs for CY8CKIT-041-41XX and CY8CKIT-149 kits. Third-party Arm® toolchains (Keil MDK, IAR EWARM, GCC) are also compatible via generated startup code and linker scripts.
