Product details
Overview
CY8C4025LQS-S411T from Infineon is an AEC-Q100 qualified automotive-grade PSoC™ 4000S microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing with >5:1 SNR, two low-power comparators active in Deep Sleep, and two current DACs-all in a 40-pin QFN package. It targets touch-enabled automotive control panels requiring robust water-tolerant sensing and motor drive PWM kill-signal triggering.
For engineers reviewing the CY8C4025LQS-S411T datasheet, CY8C4025LQS-S411T pinout, CY8C4025LQS-S411T application, or CY8C4025LQS-S411T equivalent, key selection criteria include AEC-Q100 Grade S (–40°C to +105°C), programmable analog/digital routing, TCPWM comparator-triggered kill signals, and dual SCB blocks supporting runtime-reconfigurable I²C/SPI/UART.
Technical Context
The device implements a tightly coupled system-on-chip architecture where the Arm® Cortex®-M0+ core interfaces via AHB-Lite to programmable analog blocks (CSD, IDACs, LPCs) and digital logic (TCPWM, SCBs, PLD). Its clock system integrates IMO (48 MHz), ILO (32.768 kHz), and WCO for precise timing across sleep/wake transitions.
Capacitive sensing uses sigma-delta modulation with hardware-accelerated smart tuning, enabling direct GPIO-based CSD without external components. The five 16-bit TCPWM blocks support center-aligned PWM and comparator-driven synchronous kill signals-critical for automotive motor control safety compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - enables real-time deterministic control with Thumb-2 instruction set and NVIC interrupt handling. |
| Flash / SRAM | 32 KB flash with read accelerator / 4 KB SRAM - supports firmware updates and runtime data buffering for automotive diagnostics. |
| Operating Voltage | 1.71 V to 5.5 V - allows direct interface with 3.3 V and 5 V automotive subsystems without level-shifting. |
| Deep Sleep Current | 2.5 µA digital system current - sustains wake-on-touch or timer events while minimizing battery drain in always-on modules. |

| TCPWM Blocks | Five 16-bit timer/counter/PWM units - provide independent motor phase control with comparator-triggered fault shutdown. |
| SCB Count | Two serial communication blocks - each reconfigurable at runtime as I²C, SPI, or UART for flexible sensor/actuator interfacing. |
Pinout & Package
Package: 40-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power domains | Four independent 1.71–5.5 V supplies enable mixed-voltage GPIO interfacing (e.g., 5 V sensors + 3.3 V CAN transceivers). |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[3] | Programmable GPIO | All 34 pins support CAPSENSE™, analog input, or digital logic with configurable drive strength/slew rate. |
| SWDCLK / SWDIO | Serial Wire Debug interface | Two-pin debug port enabling full-chip programming, tracing, and real-time variable inspection without JTAG overhead. |
| XRES | External reset input | Active-low asynchronous reset with internal pull-up; compatible with automotive watchdog ICs and power-supply supervisors. |
| WCO_IN / WCO_OUT | Watch Crystal Oscillator terminals | Supports 32.768 kHz crystal for RTC and low-power timekeeping during Deep Sleep mode. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware-accelerated CAPSENSE™ | Capacitive sigma-delta (CSD) engine with automatic calibration eliminates manual tuning and improves production yield on curved or coated touch surfaces. |
| Programmable analog routing | Continuous-time and switched-capacitor blocks route analog signals (e.g., IDAC → comparator → TCPWM trigger) without external op-amps or passive networks. |
| Comparator-triggered TCPWM kill | Hardware-level fault response (<100 ns latency) disables PWM outputs upon overcurrent or overtemperature detection-meeting ASIL-B functional safety requirements. |
| Runtime-reconfigurable SCBs | Each SCB dynamically switches between I²C master/slave, SPI master/slave, or UART modes via firmware-reducing BOM count in multi-sensor nodes. |
| LCD segment drive | All GPIOs double as LCD segment/common drivers-enabling direct integration of status displays without dedicated display controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4025LQI-S402T | Same die, 24-pin QFN package, 20 GPIOs, no WCO pins | Limited pin count restricts simultaneous CAPSENSE™ + motor control + display in compact modules | Select when board space is constrained and fewer peripherals are needed. |
| SPC560B50L5 | Power Architecture e200z0 core, 64 MHz, 512 KB flash, no integrated CAPSENSE™ | Requires external touch controller and analog front-end for capacitive sensing | Select for high-speed CAN-based body networks where touch is secondary to communication throughput. |
Compared with CY8C4025LQS-S411T, the CY8C4025LQI-S402T trades pin count and WCO support for smaller footprint, while the SPC560B50L5 offers higher compute headroom but adds BOM cost and design complexity for touch functionality.

FAQ
Is CY8C4025LQS-S411T qualified for automotive use?
Yes. It is AEC-Q100 qualified for Grade S (–40°C to +105°C), with full documentation including stress test reports, failure-in-time (FIT) data, and PPAP-ready manufacturing records. All wafers undergo automotive-specific process controls and lot traceability per IATF 16949.
Does it support hardware debugging in production vehicles?
Yes. The Arm® Serial-Wire Debug (SWD) interface remains fully functional in final systems using only two pins (SWDCLK/SWDIO). It enables live memory inspection, breakpoint setting, and flash reprogramming without removing the chip-critical for field firmware updates and diagnostic logging.
Can all GPIOs be used for CAPSENSE™ simultaneously?
Yes. All 34 GPIOs support CAPSENSE™ CSD functionality, with hardware arbitration ensuring no signal contention. The CSD block automatically sequences measurements across pins, delivering up to 120 Hz scan rate for 16-button layouts while maintaining >5:1 SNR under wet conditions.
