Product details
Overview
CY8C4024LQS-S413T from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 24 KB flash, 4 KB SRAM, and integrated CAPSENSE™ capacitive touch sensing. It operates from 1.71 V to 5.5 V, supports Deep Sleep mode at 2.5 µA, and includes two reconfigurable serial communication blocks (SCBs) for I²C/SPI/UART, five 16-bit TCPWMs, and programmable analog blocks including dual IDACs and low-power comparators. It targets embedded human-interface applications requiring robust touch control and mixed-signal flexibility.
For engineers reviewing the CY8C4024LQS-S413T datasheet, CY8C4024LQS-S413T pinout, CY8C4024LQS-S413T application, or CY8C4024LQS-S413T equivalent, key selection criteria include CAPSENSE™ SNR (>5:1), SmartSense auto-tuning capability, 48-MHz CPU performance, GPIO reconfigurability across analog/digital/CAPSENSE™ roles, and support for ModusToolbox™ and PSoC™ Creator development environments.
Technical Context
The device integrates a single-core Arm® Cortex®-M0+ CPU running at up to 48 MHz with hardware multiply, coupled with a flexible digital fabric including five TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals for motor control safety. Its analog subsystem features a sigma-delta CAPSENSE™ engine delivering >5:1 SNR and water tolerance, plus two current DACs and two deep-sleep-capable comparators.
System-level resources include two SCBs with runtime-reconfigurable I²C/SPI/UART protocols, a 32-kHz WCO, ±2% IMO, and 32-kHz ILO - enabling precise timing for touch scanning, real-time control, and low-power wake-up events without external crystals in many use cases.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables deterministic real-time firmware execution with single-cycle multiply for control loops and sensor processing. |
| Flash / SRAM | 24 KB flash / 4 KB SRAM - sufficient for CAPSENSE™-enabled HMI firmware with BLE stack integration or small RTOS deployments. |
| Operating Voltage | 1.71 V to 5.5 V - supports direct interface with 3.3 V logic, 5 V peripherals, and battery-powered operation down to coin-cell levels. |
| Deep Sleep Current | 2.5 µA digital system current - allows multi-year battery life in touch-button or proximity-sensing nodes with periodic wake-up. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under wet conditions and EMI-rich industrial environments. |
| TCPWM Blocks | Five 16-bit timer/counter/PWM units - supports simultaneous motor phase control, LED dimming, and encoder counting without CPU overhead. |
| SCB Interfaces | Two reconfigurable serial blocks - each can be independently set as I²C master/slave, SPI master/slave, or UART, simplifying peripheral expansion with minimal pin count. |
Pinout & Package
CY8C4024LQS-S413T is housed in a 24-pin QFN package (4 × 4 mm, 0.5 mm pitch) with wettable flank leads for automated optical inspection. All GPIOs are software-configurable for digital I/O, analog input/output, or CAPSENSE™ electrode functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply | Accepts 1.71–5.5 V; powers digital core, analog blocks, and I/O; requires local decoupling. |
| VSS | Ground reference | Digital and analog ground common point; critical for CAPSENSE™ noise immunity and ADC accuracy. |
| P0[0]–P0[7] | Programmable GPIO bank | Support CAPSENSE™, analog input, IDAC output, or digital function; slew rate and drive strength configurable per pin. |
| SWDCLK / SWDIO | Debug interface | Serial Wire Debug pins - enable full-chip programming, breakpoint debugging, and real-time trace without external emulators. |
| XRES | External reset input | Active-low asynchronous reset; debounced internally; compatible with pushbutton or supervisor IC assertion. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning across temperature/humidity variations and PCB batch differences. |
| Reconfigurable SCBs | Two independent serial blocks dynamically switch between I²C, SPI, and UART protocols at runtime - reduces BOM count and design iterations. |
| Deep Sleep Analog Operation | Analog comparators remain active during 2.5 µA Deep Sleep - enables wake-on-touch or wake-on-threshold without full MCU wake-up. |
| Programmable Drive Modes | Each GPIO supports open-drain, strong, resistive pull-up/down, and high-Z analog modes - simplifies level-shifting and mixed-voltage interfacing. |
| Integrated ROM Bootloader | 8 KB on-chip ROM contains factory-programmed bootloader - enables field firmware updates via UART/I²C without external programmer dependency. |
Applications
| Smart Home Touch Panel | Industrial HMI Keypad |
|---|---|
Use Scenario: Wall-mounted lighting and climate control panel with waterproof overlay and multi-finger gesture support. IC Role / Device Role / Timing Role: Primary MCU executing CAPSENSE™ scan, LED backlight PWM, and I²C communication to main controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S403 | Same die, 24-pin QFN but with industrial temp range (–40°C to +85°C) vs. extended (–40°C to +105°C) for S413T; identical peripherals and memory. | Suitable for non-automotive indoor applications where ambient temperature stays below 85°C. | Select S403 for cost-sensitive consumer devices with standard industrial thermal envelope. |
| CY8C4014LQI-S403 | 16 KB flash / 2 KB SRAM; lacks CAPSENSE™ v2 engine and SmartSense; only one SCB and three TCPWMs. | Targeted at simpler touchless proximity or basic control tasks without multi-electrode gesture or high-SNR requirements. | Choose only when CAPSENSE™ SNR, auto-tuning, or dual SCB functionality are not required. |
Compared with CY8C4024LQI-S403, the S413T adds extended temperature support and identical feature set; versus CY8C4014LQI-S403, it delivers 50% more memory, full CAPSENSE™ v2, and dual SCB flexibility - justifying its use in higher-integration HMI designs.

FAQ
Does CY8C4024LQS-S413T support USB connectivity?
No. This device does not include a USB PHY or USB controller. Communication is limited to the two reconfigurable SCBs supporting I²C, SPI, and UART protocols. For USB host or device functionality, an external USB-to-UART bridge or migration to a PSoC™ 4100S or PSoC™ 6 device is required.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes. The CAPSENSE™ block and associated low-power comparators remain fully operational during Deep Sleep mode with only 2.5 µA total system current. Touch scan results are stored in dedicated registers and can trigger a wake-up interrupt upon threshold crossing.
What development tools are officially supported for CY8C4024LQS-S413T?
Infineon officially supports both ModusToolbox™ (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only, schematic-driven). Hardware debug uses MiniProg4 or KitProg3 via SWD; the CY8CKIT-145-40XX prototyping kit provides direct access to all 24 pins and CAPSENSE™-optimized layout.
Is the 24 KB flash memory subject to wear-out during firmware updates?
Yes - like all flash-based MCUs, the 24 KB flash has a rated endurance of 100,000 write/erase cycles per sector. However, the on-chip ROM bootloader and configurable flash protection bits allow safe over-the-air update partitioning and lock-down of critical boot code to extend effective field lifetime.
