Product details
Overview
CY8C4025LQS-S411 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 operating in Deep Sleep mode (2.5 µA system current), and dual reconfigurable serial communication blocks (I²C/SPI/UART) - deployed in motor control interfaces and touch-enabled automotive cabin controllers.
For engineers reviewing the CY8C4025LQS-S411 datasheet, CY8C4025LQS-S411 pinout, CY8C4025LQS-S411 application, or CY8C4025LQS-S411 equivalent, key selection criteria include AEC-Q100 Grade S (–40°C to +105°C), programmable analog/digital routing, TCPWM kill-signal triggering for motor safety, and CAPSENSE™ hardware auto-tuning capability.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, flash accelerator, SRAM controller, and peripherals including five 16-bit TCPWM blocks with comparator-triggered kill signals and center-aligned PWM modes. Its analog subsystem integrates two IDACs and two low-power comparators sharing programmable I/O matrix routing.
Capacitive sensing uses sigma-delta (CSD) modulation with dedicated hardware tuning logic and supports all 34 GPIOs as CSD electrodes. The clock system includes IMO (48 MHz), ILO (32.768 kHz), and WCO inputs, enabling precise timing for both real-time control and ultra-low-power wake-up events.

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-S412 | Same die, 40-pin QFN package but AEC-Q100 E-Grade (–40°C to +125°C) and 1.8 V min supply | Targeted at under-hood applications requiring extended temperature range and tighter voltage regulation | Select when operating near engine bay or requiring higher thermal margin |
| STM32G431KB6 | Arm Cortex-M4F @ 170 MHz, 128 KB flash, no integrated CAPSENSE™, requires external touch controller | Higher compute throughput for motor FOC algorithms but adds BOM complexity for touch functionality | Choose when floating-point math dominates over capacitive sensing integration |
Compared with CY8C4025LQS-S411, the CY8C4025LQI-S412 offers extended temperature operation at the cost of stricter supply regulation, while the STM32G431KB6 delivers superior processing headroom but lacks native hardware touch sensing - increasing design effort and component count for cabin HMI systems.

FAQ
What is the maximum operating temperature grade for CY8C4025LQS-S411?
CY8C4025LQS-S411 is qualified to AEC-Q100 Grade S, supporting continuous operation from –40°C to +105°C. This rating is validated per test conditions in the official Infineon qualification report 002-18381 Rev. *K and applies to the full 40-pin QFN package configuration.
Does CY8C4025LQS-S411 support hardware-based capacitive touch sensing without external components?
Yes. It integrates a dedicated capacitance-sigma-delta (CSD) block with on-die IDACs, comparators, and hardware auto-tuning logic. All 34 GPIOs function as CSD electrodes, eliminating need for external RC networks or dedicated touch controller ICs.
Can the TCPWM blocks generate center-aligned PWM with dead-time insertion?
No. CY8C4025LQS-S411 supports center-aligned and edge-aligned PWM modes, but does not include hardware dead-time insertion. Dead-time must be implemented in firmware using TCPWM compare/capture registers and interrupt service routines.
Is SWD debug supported in Deep Sleep mode?
No. SWD interface is disabled during Deep Sleep mode to minimize current draw. Debug access resumes only after wake-up event and CPU restart. For low-power debugging, use breakpoints in active/sleep modes with SWD enabled before entering Deep Sleep.
