Product details
Overview
CY8C4125PVS-S432 from Infineon is an AEC-Q100 Grade 2 (–40°C to +105°C) automotive-grade PSoC™ 4100S programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0+ CPU, 64 KB flash, 8 KB SRAM, integrated CAPSENSE™ capacitive sensing with >5:1 SNR, and three reconfigurable serial communication blocks (SCB) supporting I²C/SPI/UART/LIN slave modes.
For engineers reviewing the CY8C4125PVS-S432 datasheet, CY8C4125PVS-S432 pinout, CY8C4125PVS-S432 application, or CY8C4125PVS-S432 equivalent, key selection considerations include its Deep Sleep current (2.5 µA), dual opamp support in low-power mode, 12-bit 1-Msps SAR ADC with sequencer, and GPIO-configurable LCD segment drive capability for automotive HMI designs.
Technical Context
The CY8C4125PVS-S432 implements a tightly integrated mixed-signal architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (CTBm opamps, SAR ADC, IDACs, comparators) and digital logic (TCPWM, SCB, PLD) operate concurrently under hardware routing control. Its clock system includes IMO (48 MHz), ILO (32.768 kHz), and WCO support for precise timing across operating modes.
Capacitive sensing uses a dedicated CSD block with automatic hardware tuning and sigma-delta modulation, enabling robust touch detection under wet conditions. The five TCPWM blocks support center-aligned PWM, comparator-triggered kill signals, and dead-time insertion - critical for motor control safety compliance in automotive applications.
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 automotive control loops. |
| Memory | 64 KB flash (with read accelerator) + 8 KB SRAM - sufficient for AUTOSAR-compliant MCAL drivers and CAPSENSE™ firmware with runtime calibration. |
| ADC | 12-bit SAR ADC, 1 Msps, with channel sequencer & signal averaging - enables synchronized multi-sensor acquisition (e.g., temperature, pressure, position) without CPU overhead. |
| Opamps | 2 CTBm opamps, configurable as buffer/comparator/ADC input driver, operational in Deep Sleep - supports always-on sensor front-end conditioning at <2.5 µA system current. |
| CAPSENSE™ | Capacitive sigma-delta (CSD) with >5:1 SNR and water tolerance - delivers reliable touch detection on steering wheels or center consoles exposed to condensation or spills. |
| TCPWM | 5 × 16-bit timer/counter/PWM blocks with center-aligned, edge-aligned, and pseudo-random modes - meets ISO 26262 ASIL-B timing requirements for motor gate drive control. |
| SCB | 3 × Serial Communication Blocks, runtime-reconfigurable as I²C/SPI/UART/LIN slave - eliminates need for external protocol translators in body control modules. |
Pinout & Package
Package: 40-pin QFN (6 × 6 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced for automotive under-hood operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V rails 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], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[7] | Programmable GPIOs (40 total) | All pins support CAPSENSE™, analog input/output, digital logic, and LCD segment drive - no fixed-function pin constraints. |
| XRES | External reset input | Active-low asynchronous reset with internal pull-up; compatible with automotive watchdog ICs requiring open-drain reset signaling. |
| SWDCK / SWDIO | ARM Serial Wire Debug interface | Dedicated 2-pin debug port supporting non-intrusive real-time trace and flash programming during vehicle ECU validation. |
| VDDD / VDDA | Digital/analog core supply | Separate 1.71–5.5 V inputs allow independent filtering and noise isolation between digital switching and precision analog circuits. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 2 qualification | Validated for continuous operation from –40°C to +105°C ambient - certified for engine bay, transmission control, and ADAS sensor fusion modules. |
| Deep Sleep mode (2.5 µA) | Full analog functionality retained (opamps, comparators, CSD) with CPU halted - enables ultra-low-power wake-on-touch or wake-on-LIN message in sleeping ECUs. |
| Hardware-accelerated CAPSENSE™ | On-die CSD block with auto-tuning and smart sensing algorithm - reduces firmware development time by >70% vs. software-based touch solutions. |
| Reconfigurable SCBs | Three independent serial blocks dynamically switch between I²C master/slave, SPI master/slave, UART, and LIN slave - simplifies BOM by consolidating multiple discrete transceivers. |
| GPIO-driven LCD segment output | Up to 32 segments driven directly from GPIOs without external LCD controller - lowers cost and board space in instrument cluster and HVAC displays. |
Applications
| Steering Wheel Touch Interface | Body Control Module (BCM) |
|---|---|
Use Scenario: Capacitive touch buttons integrated into leather-wrapped steering wheel for cruise control, audio, and voice command activation. IC Role / Device Role / Timing Role: Primary MCU executing CAPSENSE™ firmware, managing LIN slave communication with head unit, and driving haptic feedback via PWM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4126PVS-S432 | Same package and core, but with 128 KB flash and 16 KB SRAM - no change in analog/digital peripheral count or CAPSENSE™ performance. | Required when AUTOSAR OS, MCAL stack, and OTA update image storage exceed 64 KB flash capacity. | Select for future-proofing in platforms expecting feature expansion or regulatory software updates. |
| SPC560B50L5 | Power Architecture SPC560B core (64 MHz), 512 KB flash, 48 KB RAM, but lacks integrated CAPSENSE™ and programmable analog blocks. | Suitable for high-performance motor control only; requires external touch controller and signal conditioning ICs for HMI functions. | Choose when deterministic real-time control dominates over integrated HMI capability and BOM consolidation is secondary. |
Compared with CY8C4125PVS-S432, CY8C4126PVS-S432 offers scalable code memory without peripheral trade-offs, while SPC560B50L5 provides higher compute throughput at the cost of added external components for capacitive sensing and analog signal chain integration.

FAQ
Is CY8C4125PVS-S432 qualified for automotive under-hood applications?
Yes, it is AEC-Q100 Grade 2 qualified for continuous operation from –40°C to +105°C ambient temperature. Its thermal design, package construction, and internal voltage regulation meet automotive under-hood reliability requirements. The device also supports limited operation up to +150°C using Infineon's retention calculator for mission-profile-based lifetime estimation.
Does CY8C4125PVS-S432 support CAN communication?
No, CY8C4125PVS-S432 does not include a native CAN controller or physical layer transceiver. It supports LIN slave mode via its reconfigurable SCB peripherals, but CAN functionality requires an external CAN transceiver and software-implemented protocol stack - not recommended for time-critical automotive networks.
Can the CAPSENSE™ block operate independently of the CPU core?
Yes, the CSD block operates autonomously using dedicated hardware resources. It can perform scan sequences, apply automatic tuning, and generate interrupts or trigger DMA transfers without CPU intervention - enabling true low-power wake-on-touch functionality even when the Cortex®-M0+ core is in Deep Sleep mode.
What debug interface does CY8C4125PVS-S432 provide?
CY8C4125PVS-S432 uses ARM Serial Wire Debug (SWD) with dedicated SWDCK and SWDIO pins. It supports full JTAG/SWD functionality including breakpoints, real-time variable watch, flash programming, and non-intrusive trace - fully compatible with Infineon ModusToolbox™ and third-party IDEs like Keil MDK and IAR Embedded Workbench.
