Product details
Overview
CY8C4024AXI-S412 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 applications.
For engineers reviewing the CY8C4024AXI-S412 datasheet, CY8C4024AXI-S412 pinout, CY8C4024AXI-S412 application, or CY8C4024AXI-S412 equivalent, key selection criteria include its 48-MHz CPU performance, dual SCB blocks (I²C/SPI/UART), five TCPWM timers, programmable analog IDACs/comparators, and 36 GPIOs with configurable drive modes and CAPSENSE™ on any pin.
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 comparator-triggered kill signals for motor control safety. Its analog subsystem includes two low-power comparators active in Deep Sleep and a capacitance-sensing block implementing sigma-delta conversion.
System-level timing relies on multiple clock sources: ±2% internal main oscillator (IMO), 32 kHz watch crystal oscillator (WCO), and 32 kHz internal low-power oscillator (ILO). The I/O subsystem enables any of the 36 GPIOs to serve as CAPSENSE™, analog input, or digital port with programmable slew rate, drive strength, and pull-up/down configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time firmware execution with single-cycle multiply for efficient math-intensive tasks. |

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 |
|---|---|---|---|
| CY8C4025AZI-S402 | 32 KB flash, 4 KB SRAM, same package; adds USBFS block and extra SCB. | Required when USB device connectivity or third serial interface is needed. | Select if future firmware expansion or host-side USB programming is planned. |
| STM32F070F6P6 | ARM Cortex-M0, 32 MHz, 32 KB flash, no integrated CAPSENSE™; requires external touch controller or GPIO-based RC network. | Suitable for cost-sensitive designs where touch is secondary or implemented externally. | Choose only when CAPSENSE™ is not required and BOM cost reduction outweighs design complexity increase. |
Compared with CY8C4024AXI-S412, CY8C4025AZI-S402 offers higher memory and USB capability but increases cost and power in non-USB use cases; STM32F070F6P6 lacks native touch sensing, demanding additional components and firmware effort to match basic CAPSENSE™ reliability and SNR.

FAQ
What development tools are officially supported for CY8C4024AXI-S412?
Infineon officially supports ModusToolbox™ software (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only IDE with schematic capture). Both provide full peripheral configuration, CAPSENSE™ tuning tools, and debug via MiniProg4 or onboard SWD. Code examples and BSPs are hosted on Infineon's GitHub and included in installer packages.
Does CY8C4024AXI-S412 support hardware encryption or secure boot?
No. CY8C4024AXI-S412 does not include hardware cryptographic accelerators, secure boot ROM, or flash lock bits beyond standard write-protection. It relies on software-based security measures. For secure boot or AES acceleration, consider Infineon's PSoC™ 6 series, which features ARM TrustZone and dedicated crypto engines.
Can all 36 GPIOs be used simultaneously for CAPSENSE™ sensing?
Yes, all 36 GPIOs support CAPSENSE™ functionality, but practical channel count depends on mutual capacitance coupling and scan time constraints. The device supports up to 64 sensing nodes using multiplexed scanning, with hardware-accelerated sigma-delta conversion and SmartSense auto-calibration applied per node.
What is the maximum operating temperature for continuous Deep Sleep mode?
The CY8C4024AXI-S412 is rated for industrial temperature range (–40 °C to +85 °C). Deep Sleep current remains within specification (≤2.5 µA typical) across this full range, verified per datasheet Section 6.2. Thermal derating is not required for sustained Deep Sleep operation at 85 °C ambient.
