Product details
Overview
CY8C4024AZQ-S413 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, and delivers best-in-class SNR (>5:1) for water-tolerant touch interfaces in consumer HMI and industrial control panels.
For engineers reviewing the CY8C4024AZQ-S413 datasheet, CY8C4024AZQ-S413 pinout, CY8C4024AZQ-S413 application, or CY8C4024AZQ-S413 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 enabling sensor interface and motor control without external components.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core running at up to 48 MHz, paired with a flexible I/O subsystem supporting any GPIO pin for CAPSENSE™, analog, or digital functions. Its analog subsystem includes two low-power comparators active in Deep Sleep and a sigma-delta capacitive sensing engine delivering >5:1 SNR.
Digital resources include five 16-bit TCPWM blocks with center-aligned, edge-aligned, and pseudo-random PWM modes, plus two reconfigurable serial communication blocks (SCBs) supporting runtime switching between I²C, SPI, and UART protocols - all managed via hardware routing without firmware overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control in motor drives and sensor fusion. |
| Flash / SRAM | 24 KB flash with read accelerator / 4 KB SRAM - sufficient for CAPSENSE™ + BLE stack + application logic in compact embedded systems. |
| Supply Range | 1.71 V to 5.5 V - supports direct battery operation (Li-ion, 2xAA) and compatibility with 3.3 V/5 V system rails. |
| Deep Sleep Current | 2.5 µA digital system current - enables multi-year battery life in always-on touch interfaces like smart thermostats. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under moisture, gloves, or EMI-rich environments. |
| TCPWM Blocks | 5 × 16-bit timer/counter/PWM - supports simultaneous motor phase control, LED dimming, and encoder counting in single-chip designs. |
| SCB Interfaces | 2 × reconfigurable serial blocks - eliminates need for discrete protocol translators when interfacing with sensors, displays, or host MCUs. |
Pinout & Package
Package: 40-pin QFN (6 × 6 mm, 0.5 mm pitch), RoHS-compliant, wettable flank option available.
| 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 | Ground reference | Common return path for analog/digital domains; separate AGND/DGND not required due to unified I/O subsystem. |
| P0[0]–P0[7] | Programmable GPIO bank | Support CAPSENSE™, analog input/output, or digital logic; configurable slew rate and drive strength per pin. |
| SWDCLK / SWDIO | Serial Wire Debug interface | Enables full-chip debug and programming using standard Arm® SWD tools; debug can be disabled in production firmware. |
| XTAL_IN / XTAL_OUT | 32 kHz watch crystal oscillator terminals | Connects to external 32.768 kHz crystal for RTC accuracy ±20 ppm; optional internal ILO fallback. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning across temperature/humidity/voltage variations. |
| Programmable analog blocks | Two IDACs and two low-power comparators usable on any GPIO - enable sensor biasing, threshold detection, and wake-on-event in Deep Sleep. |
| Reconfigurable SCBs | Each SCB dynamically switches between I²C master/slave, SPI master/slave, or UART TX/RX - reduces BOM count in multi-interface systems. |
| LCD segment drive | Direct GPIO-based LCD segment output - supports up to 16-segment static or 4×16 multiplexed displays without external drivers. |
| Comparator-triggered kill signal | Hardware link from comparator output to TCPWM fault input - provides <100 ns response for overcurrent shutdown in motor gate drivers. |

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 |
|---|---|---|---|
| CY8C4025AZQ-S413 | 28 KB flash, same package and peripherals - adds 4 KB flash for larger firmware or bootloader space. | Suitable where field-upgradable firmware or secure boot requires extra non-volatile storage. | Select when future firmware expansion or dual-bank OTA updates are required. |
| CY8C4014LQI-S403 | 32-pin QFN, 16 KB flash, no WCO support - lower pin count and memory, lacks 32 kHz crystal oscillator. | Better fit for space-constrained, cost-sensitive designs without RTC or high-precision timing needs. | Select for minimal-footprint HMI where Deep Sleep current remains identical but crystal dependency is removed. |
Compared with CY8C4024AZQ-S413, CY8C4025AZQ-S413 offers headroom for complex CAPSENSE™+BLE stacks, while CY8C4014LQI-S403 trades flash and timing precision for reduced size and cost - both retain identical analog/digital peripheral architecture and Deep Sleep behavior.

FAQ
What development tools are officially supported for CY8C4024AZQ-S413?
Infineon officially supports ModusToolbox™ software and PSoC™ Creator IDE for firmware development, debugging, and hardware configuration. Both tools provide full access to CAPSENSE™ tuning, TCPWM setup, and SCB reconfiguration. MiniProg4 is the recommended programmer/debugger, and CY8CKIT-145-40XX serves as the reference evaluation kit with breadboard-compatible pin breakout.
Does CY8C4024AZQ-S413 support hardware encryption or secure boot?
CY8C4024AZQ-S413 does not include dedicated cryptographic accelerators or hardware secure boot circuitry. It supports flash protection bits and debug disable to prevent unauthorized access, but secure firmware validation must be implemented in software using external trusted elements or higher-tier PSoC™ 6 devices with PSA-certified security features.
Can all GPIO pins be used simultaneously for CAPSENSE™ and analog functions?
Yes - any of the 36 GPIO pins can be assigned to CAPSENSE™, analog input/output, or digital functions in the same design. However, concurrent use of the same pin for CAPSENSE™ and analog output is prohibited; the device's hardware routing automatically resolves conflicts during component configuration in PSoC™ Creator or ModusToolbox™.
What is the maximum operating temperature for continuous Deep Sleep mode?
The device maintains guaranteed Deep Sleep operation at 2.5 µA system current up to +85 °C ambient temperature. At +105 °C, Deep Sleep current rises to 4.1 µA per datasheet Section 6.2 - still suitable for industrial enclosures with passive thermal management, but not rated for extended operation above +105 °C.
