Product details
Overview
CY8C4147AZS-S455 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade 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 controller with TTCAN support - deployed in body control modules and door module ECUs requiring robust touch + communication integration.
For engineers reviewing the CY8C4147AZS-S455 datasheet, CY8C4147AZS-S455 pinout, CY8C4147AZS-S455 application, or CY8C4147AZS-S455 equivalent, key selection criteria include its dual-mode SCB serial blocks (I²C/SPI/UART/LIN), eight TCPWM units with quadrature decode and kill-input triggering, 12-bit 1-Msps SAR ADC, Deep Sleep current of 2.5 µA, and programmable analog blocks supporting opamp-comparator-ADC-IDAC co-location on any GPIO.
Technical Context
This device implements a mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTBm opamps, SAR ADC, IDACs) and digital (TCPWM, SCB, Smart I/O) blocks are configured at design time via PSoC™ Creator. Its CAN 2.0B block supports time-triggered operation for deterministic messaging in distributed automotive networks.
The clock system integrates four independent sources - 4–33 MHz ECO, 32-kHz WCO, ±2% IMO, and 32-kHz ILO - enabling precise timing for CAN bit timing, PWM synchronization, and low-power wake-up events without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz - enables real-time control with Thumb-2 instruction set and NVIC interrupt handling |
| Flash / SRAM | 128 KB flash with Read Accelerator + 16 KB SRAM - supports complex firmware with bootloader, CAPSENSE™ tuning, and CAN protocol stack |
| ADC | 12-bit 1-Msps SAR ADC with channel sequencer and averaging - delivers high-resolution sensor acquisition for temperature, position, or battery monitoring |
| CAN Interface | CAN 2.0B with TTCAN support - provides deterministic, time-synchronized messaging for chassis and body domain controllers |
| Capacitive Sensing | CAPSENSE™ CSD with >5:1 SNR and SmartSense auto-tuning - enables reliable touch buttons/knobs under moisture or EMI without manual calibration |
| Low-Power Modes | Deep Sleep mode draws 2.5 µA digital current while retaining RAM and operating analog blocks - ideal for always-on wake-on-touch or CAN bus monitoring |
| GPIO Count | Up to 54 programmable pins - each configurable as CAPSENSE™, analog input/output, digital logic, or LCD segment driver |
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. *P, Section 2 "Pinouts".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Independent 1.71–5.5 V supplies per port group - 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 comparator input, IDAC sink/source, or TCPWM capture - no fixed peripheral binding |
| CAN_TX / CAN_RX | Dedicated CAN transceiver interface | Internal differential driver/receiver compliant with ISO 11898-2 - requires external CAN PHY but eliminates external level-shifting |
| XRES | Reset input | Active-low reset with internal pull-up and glitch filter - compatible with automotive watchdog ICs and power supply supervisors |
| SWDCK / SWDIO | ARM Serial Wire Debug | Two-pin debug interface supporting flash programming, real-time trace, and breakpoint debugging without JTAG overhead |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration that dynamically adjusts IDAC current and scan parameters - eliminates factory calibration and field drift compensation code |
| Configurable SCBs | Five serial blocks each reconfigurable at runtime as I²C master/slave, SPI master/slave, UART, or LIN slave - reduces BOM count versus discrete protocol ICs |
| TCPWM kill-input | Hardware-level fault response: comparator output directly disables PWM outputs within one clock cycle - meets ASIL-B functional safety requirements for motor drive protection |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain active during 2.5 µA Deep Sleep - enables continuous sensor monitoring without CPU wake-up latency |
| True Random Number Generator (TRNG) | Digital entropy source certified per NIST SP 800-90B - provides cryptographically secure keys for secure boot and OTA update authentication |
Applications
| Body Control Module (BCM) | Door Module ECU |
|---|---|

IC Role / Device Role / Timing Role: Low-power Deep Sleep wake-on-touch + SmartSense auto-tuning + CAN message transmission upon gesture recognition. Use Value: 2.5 µA Deep Sleep current extends vehicle battery life during extended parking; auto-tuning maintains consistent sensitivity across temperature (-40°C to +105°C). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core, 112 MHz, 1 MB flash, no integrated CAPSENSE™; requires external touch controller | Targets higher-performance powertrain/safety apps; lacks native capacitive sensing hardware acceleration | Select when floating-point math, larger memory, or AUTOSAR OS support is required - not drop-in for CAPSENSE™-centric designs |
| Renesas RL78/F14 | 16-bit RL78 core, 32 MHz, 512 KB flash, integrated touch I/O but no CAN FD or TTCAN; lower SNR CAPSENSE™ | Focused on cost-sensitive entry-level body electronics; limited CAN feature set and no hardware SmartSense | Choose for legacy 16-bit migration or ultra-low-cost BCMs where TTCAN and >5:1 SNR are not required |
Compared with S32K144 and RL78/F14, CY8C4147AZS-S455 uniquely combines automotive CAN with production-ready CAPSENSE™ and sub-µA wake-on-touch - making it optimal for next-gen human-machine interfaces where touch + communication integration reduces system complexity and validation effort.

FAQ
Does CY8C4147AZS-S455 support CAN FD?
No. This device implements a CAN 2.0B controller with Time-Triggered CAN (TTCAN) capability only. It does not support CAN FD data rates or extended frame formats. For CAN FD requirements, consider Infineon's AURIX™ TC3xx family or evaluate external CAN FD transceivers with protocol translation firmware.
What development tools are required for CAPSENSE™ tuning?
PSoC™ Creator IDE (v4.4 or later) is mandatory for CAPSENSE™ configuration and SmartSense auto-tuning. The kit includes built-in tuning GUI and real-time signal-to-noise ratio visualization. No external oscilloscope or logic analyzer is needed for baseline tuning - all calibration runs in-system via SWD interface.
Is the TRNG FIPS 140-2 certified?
The TRNG block meets NIST SP 800-90B entropy requirements and is used in Infineon's secure boot implementation, but full FIPS 140-2 certification applies to the complete PSoC™ 4100S Plus security subsystem only when deployed with specific firmware configurations and external cryptographic libraries - not the TRNG alone.
Can GPIO pins be used simultaneously for CAPSENSE™ and analog ADC input?
Yes - any GPIO pin can be dynamically reassigned between CAPSENSE™ CSD electrode, SAR ADC input, opamp output, or digital function. However, concurrent use on the same pin is prohibited; time-multiplexing (e.g., CAPSENSE™ scan during idle, ADC sampling during active control) is supported via firmware scheduling.
