Product details
Overview
CY8C4024AZI-S413T from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 24 KB flash, 4 KB SRAM, and integrated CAPSENSE™ capacitive touch-sensing engine. 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 human interface applications in industrial HMI and consumer appliances.
For engineers reviewing the CY8C4024AZI-S413T datasheet, CY8C4024AZI-S413T pinout, CY8C4024AZI-S413T application, or CY8C4024AZI-S413T equivalent, key selection criteria include its 48-MHz CPU performance, dual SCB blocks supporting I²C/SPI/UART reconfiguration, five TCPWM modules with comparator-triggered kill signals, and programmable analog blocks including two IDACs and two low-power comparators.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core running at up to 48 MHz, coupled with a flexible digital fabric including five 16-bit TCPWM blocks supporting center-aligned PWM and hardware kill signal generation for motor control safety. Its analog subsystem includes a sigma-delta CAPSENSE™ engine with automatic SmartSense tuning and two current DACs usable on any GPIO.
System-level timing relies on multiple clock sources: a ±2% internal main oscillator (IMO), 32 kHz watch crystal oscillator (WCO), and 32 kHz internal low-power oscillator (ILO). The device uses a single-layer AHB interconnect and supports full SWD debug without external pods, enabling in-system firmware update and real-time trace via standard production silicon.
Key Specifications

Use Value: Programmable drive strength and slew rate mitigate EMI-induced false touches; CAPSENSE™ v2 meets ISO 11452-4 radiated immunity requirements. |
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 |
|---|---|---|---|
| CY8C4014LQI-S403 | 16 KB flash, no WCO, 24-pin QFN - lower pin count and memory, lacks watch crystal oscillator. | Suitable for space-constrained, cost-sensitive touch-only nodes without real-time clock requirements. | Select when RTC functionality is unnecessary and PCB area is premium; verify CAPSENSE™ channel count suffices. |
| STM32G031F8P6 | Arm® Cortex®-M0+, 64 KB flash, no integrated CAPSENSE™ - requires external touch controller or software-based sensing with higher CPU load. | Better for general-purpose control with high flash demand but no native capacitive sensing. | Choose only if touch is implemented externally or via GPIO-based RC decay; adds firmware complexity and reduces SNR margin. |
Compared with CY8C4014LQI-S403 and STM32G031F8P6, the CY8C4024AZI-S413T uniquely combines certified CAPSENSE™ hardware, WCO support for accurate timekeeping, and TCPWM kill signaling - making it optimal for safety-aware, touch-centric embedded systems where analog integration reduces component count and improves noise immunity.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4024AZI-S413T?
The CY8C4024AZI-S413T features an Arm® Cortex®-M0+ CPU with a maximum clock frequency of 48 MHz, supported by a ±2% internal main oscillator (IMO) and optional external crystal sources. This frequency enables real-time execution of CAPSENSE™ algorithms, TCPWM modulation, and communication stack processing without external clock components in most designs.
Does CY8C4024AZI-S413T support hardware-accelerated capacitive touch sensing?
Yes - it integrates CAPSENSE™ v2, a dedicated sigma-delta capacitive sensing engine with automatic SmartSense tuning, >5:1 signal-to-noise ratio, and water tolerance. Unlike software-based solutions, this hardware block operates independently of the CPU, enabling ultra-low-power wake-on-touch with sub-millisecond response and no firmware overhead.
Can the serial communication blocks (SCBs) be reconfigured dynamically during runtime?
Yes - each of the two SCBs can be independently reconfigured between I²C, SPI, and UART protocols in real time via firmware API calls. This capability allows a single hardware design to support multiple communication topologies without pin remapping or external multiplexers, simplifying validation and field updates.
What debug interface does CY8C4024AZI-S413T use, and is external hardware required?
The device uses Arm® Serial Wire Debug (SWD) with two dedicated pins (SWDCLK and SWDIO). No external debug pod or emulator is needed - MiniProg4 or compatible SWD programmers connect directly to these pins for full programming, breakpoint debugging, and real-time trace using standard production silicon.
