Product details
Overview
CY8C4024LQS-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 (SCB) supporting I²C/SPI/UART - deployed in automotive body electronics for touch-enabled control panels.
For engineers reviewing the CY8C4024LQS-S411 datasheet, CY8C4024LQS-S411 pinout, CY8C4024LQS-S411 application, or CY8C4024LQS-S411 equivalent, key selection criteria include AEC-Q100 Grade S (–40°C to +105°C), programmable analog/digital routing, CAPSENSE™ hardware acceleration, TCPWM kill-signal triggering for motor safety, and SWD debug interface compatibility with industry-standard tools.
Technical Context
The device implements a tightly coupled subsystem where the Arm® Cortex®-M0+ core executes firmware while programmable digital logic blocks perform Boolean operations directly on GPIOs without CPU intervention. Its analog subsystem integrates two current DACs (IDACs) and two low-power comparators that remain active during Deep Sleep, enabling wake-on-touch functionality with sub-µA quiescent current.
Capacitive sensing uses a dedicated sigma-delta (CSD) engine with automatic hardware tuning and water-tolerance support, while five 16-bit TCPWM blocks provide center-aligned PWM, comparator-triggered kill signals, and dead-time insertion - critical for automotive motor control and LED dimming applications requiring functional safety awareness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ running at 48 MHz - enables real-time deterministic execution of automotive control loops and sensor fusion algorithms. |
| Flash / SRAM | 32 KB flash with read accelerator + 4 KB SRAM - supports secure boot, OTA update partitions, and real-time data buffering without external memory. |
| Operating Voltage | 1.71 V to 5.5 V - allows direct connection to 3.3 V or 5 V automotive power domains without level-shifting circuitry. |
| Deep Sleep Current | 2.5 µA digital system current - enables always-on capacitive touch wake-up in battery-constrained modules like door handles or seat controls. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under condensation, glove use, or electromagnetic noise in vehicle cabins. |
| TCPWM Blocks | Five 16-bit timer/counter/PWM units - deliver synchronized, fault-protected PWM generation for multi-phase motor drivers or RGB LED clusters. |
| SCBs | Two reconfigurable serial communication blocks - each supports runtime-switchable I²C, SPI, or UART protocols for flexible sensor/actuator interfacing. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 1.71–5.5 V; powers digital core, analog blocks, and I/O; requires local 100 nF decoupling per supply pin. |
| GND | Ground reference | Common return path for analog/digital domains; connected to exposed thermal pad for thermal dissipation and EMI reduction. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up enables single-button reset without external resistor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S402 | Same die, 24-pin QFN but A-Grade (–40°C to +85°C); lacks AEC-Q100 certification | Restricted to non-automotive industrial or consumer touch interfaces | Select only if automotive qualification is not required and cost sensitivity outweighs environmental robustness. |
| STM32G071KBT6 | Arm® Cortex®-M0+, 64 KB flash, no integrated CAPSENSE™ or programmable analog; requires external touch controller | Suitable for general-purpose automotive control where capacitive sensing is handled externally | Choose when leveraging existing STM32 ecosystem tools and when analog flexibility is secondary to flash size and peripheral count. |
Compared with CY8C4024LQS-S411, CY8C4024LQI-S402 offers identical functionality without automotive qualification, while STM32G071KBT6 trades programmable analog integration for larger flash and broader third-party tool support - making the CY8C4024LQS-S411 optimal for cost-constrained, safety-aware capacitive touch systems.

FAQ
What is the maximum operating temperature rating for CY8C4024LQS-S411?
CY8C4024LQS-S411 is rated for Grade S operation: –40°C to +105°C ambient temperature. This specification is validated per AEC-Q100 stress test conditions and applies to continuous operation in automotive cabin environments, including locations near HVAC ducts or sun-exposed dashboards.
Does CY8C4024LQS-S411 support hardware-based secure boot?
CY8C4024LQS-S411 does not include dedicated secure boot hardware such as cryptographic accelerators or immutable ROM-based bootloaders. It supports flash protection mechanisms and debug disable features, but secure boot implementation requires external authentication ICs or firmware-level signature verification using its 32 KB flash and SRAM resources.
Can all GPIO pins be used simultaneously for CAPSENSE™ and analog measurement?
Yes - all 34 GPIO pins support CAPSENSE™ and analog functions including ADC, IDAC, and comparator inputs. However, simultaneous use requires careful resource allocation: the capacitance sensing block shares analog routing paths, so concurrent high-speed ADC sampling and CSD scanning must be sequenced via firmware-controlled time-division multiplexing to avoid signal crosstalk.
Is SWD debug supported in Deep Sleep mode?
No - Serial Wire Debug (SWD) is disabled in Deep Sleep mode to maintain 2.5 µA system current. Debug access requires waking the device into Active or Sleep mode first. The SWD interface remains fully functional in Sleep mode (with clocks running) and supports breakpoints, register inspection, and memory reads without full wake-up.
