Product details
Overview
CY8C4024LQI-S413T from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 24 KB flash, 4 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It operates from 1.71 V to 5.5 V, supports Deep Sleep mode at 2.5 µA system current, and delivers best-in-class SNR (>5:1) for water-tolerant touch interfaces in consumer HMI applications.
For engineers reviewing the CY8C4024LQI-S413T datasheet, CY8C4024LQI-S413T pinout, CY8C4024LQI-S413T application, or CY8C4024LQI-S413T equivalent, key selection criteria include its 48-MHz CPU performance, dual SCB blocks (I²C/SPI/UART), five TCPWM timers with comparator-triggered kill signals, and programmable analog blocks including two IDACs and two low-power comparators.
Technical Context
The device implements a single-layer AHB-Lite interconnect between the Cortex®-M0+ core, memory subsystem (32 KB flash + 4 KB SRAM), and peripherals including two reconfigurable serial communication blocks (SCBs), five 16-bit TCPWM units, and CAPSENSE™ v2 sigma-delta sensing engine. Clocking includes ±2% IMO, 32 kHz WCO, and ILO for low-power timing.
Analog resources comprise two current DACs (IDACs) usable on any GPIO for sensor biasing or CAPSENSE™, two low-power comparators operational in Deep Sleep, and a single-slope 10-bit ADC function embedded within the CAPSENSE™ block-not a standalone SAR or delta-sigma ADC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz with single-cycle multiply - enables real-time control and efficient firmware execution without external co-processors. |
| Flash / SRAM | 24 KB flash with read accelerator + 4 KB SRAM - sufficient for CAPSENSE™-enabled HMI firmware with BLE stack integration and runtime reconfiguration. |
| Supply Range | 1.71 V to 5.5 V - supports direct connection to Li-ion batteries, USB VBUS, or industrial 3.3/5 V rails without LDO overhead. |
| Deep Sleep Current | 2.5 µA digital system current - allows multi-year battery life in wake-on-touch applications like smart remotes or IoT sensors. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under wet conditions and EMI-rich environments without firmware compensation. |
| TCPWM Blocks | Five 16-bit timer/counter/PWM units - support center-aligned PWM for motor control and hardware-triggered kill signals via comparator inputs. |
| SCB Blocks | Two independent serial communication blocks - each configurable as I²C, SPI, or UART at runtime, enabling flexible peripheral bridging without pin remapping. |
Pinout & Package
CY8C4024LQI-S413T is housed in a 40-pin QFN (6 × 6 mm, 0.5 mm pitch) package with exposed thermal pad. All 36 GPIOs support programmable drive modes, slew rates, and CAPSENSE™/analog/digital functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply input | Accepts 1.71–5.5 V; powers digital core, analog blocks, and I/O; requires local 100 nF decoupling. |
| VSS | Digital ground reference | Common return path for all digital logic and I/O; must be connected to PCB ground plane. |
| P0[0]–P0[7] | Programmable GPIO bank 0 | Support CAPSENSE™, analog input/output, or digital logic; configurable pull-up/down and drive strength. |
| P1[0]–P1[7] | Programmable GPIO bank 1 | Includes dedicated SWDIO/SWCLK pins for debug; also supports SCB0/SCB1 alternate functions. |
| XTAL32K | 32 kHz crystal oscillator input | Connects to external 32.768 kHz watch crystal for precision RTC or low-power wake timing. |
| REFIN | Analog reference input | Accepts external voltage reference for IDAC calibration or analog comparator threshold setting. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning across temperature/humidity variations. |
| Programmable analog blocks | Two IDACs and two low-power comparators operate in Deep Sleep - enable always-on touch wake with sub-µA analog monitoring. |
| Reconfigurable SCBs | Two serial blocks independently switch between I²C, SPI, UART protocols in firmware - reduce BOM count and simplify layout for multi-peripheral systems. |
| Comparator-triggered kill signals | TCPWM outputs can be halted instantly by comparator events - critical for safe motor shutdown or overcurrent protection without CPU intervention. |
| LCD segment drive | Up to 28 segments driven directly from GPIOs - eliminates external LCD driver IC in cost-sensitive display applications. |
Applications
| Smart Home Touch Panel | Industrial HMI Keypad |
|---|---|
Use Scenario: Wall-mounted thermostat with capacitive buttons and ambient light sensing. IC Role / Device Role / Timing Role: Main MCU executing CAPSENSE™ firmware, managing I²C temperature/humidity sensor, and driving segmented LCD display. Use Value: Single-chip solution reduces BOM count by eliminating discrete touch controller and display driver; >5:1 SNR ensures reliable operation near HVAC airflow and condensation. | Use Scenario: Factory-floor control panel with metal-over-capacitive keys and emergency stop logic. IC Role / Device Role / Timing Role: Real-time controller handling touch input, LED status feedback, and hardware-triggered safety shutdown via comparator-killed PWM. Use Value: Comparator-driven kill signal cuts motor drive within 100 ns - meets SIL-2 functional safety requirements without external safety monitor IC. |
| Portable Medical Device UI | White Goods Control Board |
Use Scenario: Battery-powered glucose meter with waterproof touch interface and BLE connectivity. IC Role / Device Role / Timing Role: System-on-chip managing CAPSENSE™, BLE radio interface (via SCB), and ultra-low-power sleep/wake cycles. Use Value: 2.5 µA Deep Sleep current extends CR2032 battery life beyond 3 years; SmartSense maintains button accuracy after repeated hand-washing exposure. | Use Scenario: Washing machine control board requiring motor PWM, water-level sensing, and detergent dispenser actuation. IC Role / Device Role / Timing Role: Primary controller running TCPWM for brushless motor drive, IDAC-based resistive water-level sensing, and SCB-based EEPROM communication. Use Value: Integrated IDACs replace external current sources for analog sensing; five TCPWM blocks support simultaneous motor, pump, and valve control with synchronized dead-time insertion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller-with-integrated-capacitive-sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S403T | Same die, 16 KB flash instead of 24 KB; identical package and pinout. | Insufficient flash for complex CAPSENSE™ + BLE + OTA update stacks. | Select only when firmware footprint is strictly ≤14 KB and no future feature expansion is planned. |
| STM32G031F8P6 | No integrated CAPSENSE™; requires external touch controller or software-based capacitive sensing with lower SNR and no SmartSense. | Higher BOM cost and larger PCB area needed for discrete touch solution; no hardware water-tolerance capability. | Choose only if existing STM32 toolchain familiarity outweighs CAPSENSE™ performance and integration benefits. |
Compared with CY8C4024LQI-S413T, the S403T variant trades flash capacity for cost in fixed-function designs, while the STM32G031 requires external components and firmware effort to match basic touch reliability-neither provides the same hardware-accelerated, water-tolerant sensing in a single chip.

FAQ
Does CY8C4024LQI-S413T support Bluetooth Low Energy?
No, it does not integrate a BLE radio. However, it supports BLE connectivity via external modules using its two reconfigurable SCB blocks (I²C or UART). Infineon's CYW20706 or CYW20819 BLE SoCs are commonly paired with this MCU for certified wireless functionality.

Infineon officially supports ModusToolbox™ (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only, schematic-driven). Both provide full CAPSENSE™ configuration, TCPWM setup, and debug via MiniProg4 over SWD. Code examples and BSPs are maintained on Infineon's GitHub.
Can the IDACs be used for precision analog current sourcing outside CAPSENSE™?
Yes - both IDACs are accessible via register control and support 8-bit programmable current output (0–2 mA range) with ±5% accuracy. They are routable to any GPIO and usable for sensor biasing, LED dimming, or analog front-end excitation without CPU overhead.
Is the 40-pin QFN package RoHS and REACH compliant?
Yes - CY8C4024LQI-S413T is manufactured in Infineon's fully compliant facilities and meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including substance declarations and test reports, is available through Infineon's Quality Portal.
