Product details
Overview
CY8C4147AZE-S245 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 SmartSense auto-tuning. It includes a CAN 2.0B block with TTCAN support, five reconfigurable SCBs (I²C/SPI/UART/LIN), and eight TCPWM blocks - deployed in automotive body electronics, smart sensors, and infotainment control units.
For engineers reviewing the CY8C4147AZE-S245 datasheet, CY8C4147AZE-S245 pinout, CY8C4147AZE-S245 application, or CY8C4147AZE-S245 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAN 2.0B with time-triggered capability, CAPSENSE™ SNR >5:1 under wet conditions, and Deep Sleep current of 2.5 µA with active analog.
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, PLL for 48-MHz core clock, 32-kHz WCO, ±2% IMO, and 32-kHz ILO - enabling precise timing for CAN bus synchronization, PWM motor control, and CAPSENSE™ sigma-delta acquisition with hardware-accelerated signal averaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - delivers deterministic real-time control with Thumb-2 instruction set and NVIC for automotive interrupt latency requirements. |
| Memory | 128 KB flash (with Read Accelerator), 16 KB SRAM - supports secure bootloader storage, dual-bank firmware updates, and real-time sensor data buffering. |
| CAN Interface | CAN 2.0B with TTCAN support - enables time-triggered communication for synchronized actuator control and fault-tolerant diagnostics in chassis modules. |
| CAPSENSE™ Performance | Sigma-delta CSD with SNR >5:1 and water tolerance - allows reliable touch interface operation in humid cabin environments without shielded overlays. |
| Power Modes | Deep Sleep: 2.5 µA with active analog; Operating range: 1.71–5.5 V - supports battery-backed always-on sensing and wide-input automotive power rail compatibility. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended, channel sequencer with hardware averaging - enables high-fidelity temperature, pressure, and position signal acquisition. |
| GPIO | Up to 54 pins, all CAPSENSE™/analog/digital configurable, programmable drive strength/slew rate - eliminates external level shifters and simplifies PCB routing for multi-function I/O. |
Pinout & Package
CY8C4147AZE-S245 is housed in a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully reconfigurable via PSoC™ Creator or ModusToolbox™; no fixed peripheral pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply rails | Independent 1.71–5.5 V domains per port group - enable mixed-voltage interfacing (e.g., 3.3 V MCU logic with 5 V analog sensors). |
| VDDD / VDDA | Digital/analog core supply | Separate regulated inputs decouple noise-sensitive analog blocks from digital switching transients. |
| XTAL_IN / XTAL_OUT | External crystal oscillator terminals | Support 4–33 MHz ECO for CAN bit timing accuracy and low-jitter clock synthesis via integrated PLL. |
| CAN_TX / CAN_RX | Dedicated CAN physical layer I/O | Internal termination and slew-rate control compliant with ISO 11898-2; require external CAN transceiver for bus connection. |
| SWDCLK / SWDIO | ARM Serial Wire Debug interface | Two-pin debug interface supporting full-speed programming, real-time trace, and non-intrusive breakpoints during vehicle ECU validation. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning across temperature/humidity/voltage - reduces development time by >70% for touch HMI certification. |
| Programmable Analog Blocks | Two opamps with internal/external drive modes and ADC input buffering - enable direct sensor signal conditioning (e.g., bridge amplification) without external opamp ICs. |
| Reconfigurable SCBs | Five serial blocks independently assignable as I²C master/slave, SPI master/slave, UART, or LIN slave - supports concurrent communication with multiple ECUs using shared PCB layout. |
| TTCAN Support | Time-triggered CAN scheduling with guaranteed message transmission windows - satisfies ASAM MCD-2 MC and AUTOSAR COM stack timing constraints. |
| True Random Number Generator | On-chip TRNG compliant with NIST SP 800-90B - provides entropy source for TLS handshake keys and secure boot signature verification in OTA update systems. |

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, 1 MB flash, no integrated CAPSENSE™, includes Ethernet MAC | Better for gateway/centralized ECU roles requiring higher compute or networking; lacks native capacitive sensing IP | Select when CAN/Ethernet coexistence and floating-point math are required over touch integration. |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, 512 KB flash, AEC-Q100 Grade-2, no CAN FD or TTCAN | Lower-cost entry-level body control; limited to classical CAN 2.0A/B without time-triggered scheduling | Choose for cost-sensitive non-safety-critical modules where TTCAN and CAPSENSE™ are not needed. |
Compared with S32K144W and RL78/F14, CY8C4147AZE-S245 uniquely combines AEC-Q100 Grade-S operation, on-die CAPSENSE™ with SmartSense, TTCAN, and sub-3 µA Deep Sleep - making it optimal for distributed, touch-enabled, safety-aware automotive nodes where integration density and ultra-low standby power are critical.

FAQ
Does CY8C4147AZE-S245 support CAN FD?
No. CY8C4147AZE-S245 integrates a CAN 2.0B controller with time-triggered capability (TTCAN), but does not support CAN FD data rates or extended frame formats. Its CAN block complies with ISO 11898-1:2015 for classical CAN only, with bit rates up to 1 Mbps and hardware timestamping for synchronization.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator (legacy Windows IDE) and ModusToolbox™ (cross-platform, Eclipse-based). Both provide full peripheral configuration, CAPSENSE™ tuning, TCPWM setup, and CAN register mapping. Debug requires MiniProg3 or KitProg3; no third-party JTAG adapters are qualified for production programming.
Is the 12-bit SAR ADC capable of simultaneous sampling?
No. The 12-bit SAR ADC has a single conversion engine with hardware channel sequencing and averaging, but no true simultaneous sampling across multiple channels. It achieves effective throughput of 1 Msps by interleaving conversions with DMA transfer - sufficient for multi-sensor acquisition with <1 µs inter-channel skew.
How is CAPSENSE™ water tolerance achieved in this part?
CAPSENSE™ water tolerance is achieved through sigma-delta CSD modulation combined with hardware-accelerated baseline tracking and SmartSense auto-calibration. The analog front-end rejects common-mode noise from conductive water films, and firmware algorithms dynamically adjust scan parameters to maintain >5:1 SNR even with 0.5 mm water overlay - validated per IEC 61000-4-6.
