Product details
Overview
CY8C4124AZI-S413 from Infineon is a programmable 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 64 KB flash, 8 KB SRAM, integrated CAPSENSE™ capacitive sensing, and reconfigurable analog/digital blocks. It supports deep-sleep operation at 2.5 µA digital current, includes three SCBs for I²C/SPI/UART, five TCPWM blocks, and operates across 1.71–5.5 V for industrial human-interface and embedded control applications.
For engineers reviewing the CY8C4124AZI-S413 datasheet, CY8C4124AZI-S413 pinout, CY8C4124AZI-S413 application, or CY8C4124AZI-S413 equivalent, key selection considerations include its 48LD TQFP package, 36 GPIOs with programmable drive modes, SAR ADC performance (12-bit, 1 Msps), CAPSENSE™ SNR (>5:1), and SmartSense auto-tuning capability for robust touch design.
Technical Context
The device integrates a fixed-function Arm® Cortex®-M0+ core with configurable analog (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital (TCPWM, SCB, PLD) peripherals. Its clock system combines ±2% IMO, 32 kHz ILO, and WCO for precision timing in mixed-signal operation.
Capacitive sensing uses sigma-delta modulation with hardware-accelerated SmartSense tuning and >5:1 SNR-enabling water-tolerant touch interfaces without firmware calibration. All GPIOs support CAPSENSE™, analog input, or digital I/O with programmable slew rate and drive strength.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with single-cycle multiply for motor or sensor processing. |
| Memory | 64 KB flash + 8 KB SRAM - sufficient for complex CAPSENSE™ + communication stack + application logic in standalone HMI designs. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended - supports high-fidelity sensor acquisition (e.g., temperature, pressure) with sequencer and averaging. |
| Power Consumption | 2.5 µA in Deep Sleep with analog active - allows battery-powered touch interfaces to operate for years on coin cells. |
| CAPSENSE™ Performance | Sigma-delta architecture with >5:1 SNR and water tolerance - delivers reliable touch detection in humid or wet environments without shielding. |
| Serial Interfaces | 3 × SCBs supporting I²C/SPI/UART concurrently - enables simultaneous sensor hub (I²C), display interface (SPI), and debug/communication (UART). |
| PWM/Timing | 5 × 16-bit TCPWM blocks with center-aligned, quadrature decode, and comparator-triggered kill - suitable for BLDC motor control and encoder feedback. |
Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply | Accepts 1.71–5.5 V; powers digital core, SRAM, and most analog blocks. |
| VSS | Digital ground | Reference return path for digital logic and I/O buffers. |
| XRES | Active-low reset input | Asynchronous external reset with internal pull-up; debounced by hardware. |
| SWDCLK / SWDIO | Debug interface | Two-pin Serial Wire Debug for programming and real-time trace via ModusToolbox™ or PSoC™ Creator. |
| P0[0]–P0[7] | General-purpose GPIO | Support CAPSENSE™, analog input, UART TX/RX, I²C SDA/SCL, or PWM output; programmable drive strength (0.5–20 mA). |
| P1[0]–P1[7] | General-purpose GPIO | Same capabilities as P0; includes dedicated LCD segment drive capability on select pins. |
| XTAL_IN / XTAL_OUT | 32 kHz crystal oscillator terminals | Connects to external watch crystal for precise RTC or low-power wake-up timing. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning and maintains stable touch performance across voltage/temperature drift. |
| Reconfigurable SCBs | Three independent serial blocks each dynamically assignable as I²C master/slave, SPI master/slave, or UART - reduces BOM count and PCB routing complexity. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain operational during 2.5 µA Deep Sleep - enables low-power sensor wake-up without full MCU restart. |
| Programmable GPIO drive | Each pin supports 12 drive modes (e.g., strong, open-drain, high-Z analog) and adjustable slew rate - prevents EMI and signal integrity issues in mixed-signal layouts. |
| Capacitive sigma-delta sensing | Dedicated CSD block achieves >5:1 SNR and water tolerance - allows direct front-panel integration without overlay shielding or guard traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller with capacitive sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S412 | Lower memory (32 KB flash, 4 KB SRAM), no TCPWM kill-input trigger, 32-pin QFN package. | Limited to simpler touch-only HMI without motor control or multi-sensor fusion. | Select when cost and footprint are critical and advanced timing features are unnecessary. |
| STM32G031F8P6 | No integrated CAPSENSE™; requires external RC network and firmware-based touch algorithm; 16 KB flash, 8 KB SRAM, Cortex-M0+ @ 64 MHz. | Higher firmware development effort for touch; less robust against water/noise without hardware sigma-delta. | Choose if existing STM32 toolchain familiarity outweighs CAPSENSE™ hardware advantage and system-level noise immunity. |
Compared with CY8C4124AZI-S413, CY8C4024LQI-S412 sacrifices memory and advanced PWM safety features for lower cost and size, while STM32G031F8P6 shifts capacitive sensing burden to software-increasing validation time and reducing noise/water resilience.

FAQ
Does CY8C4124AZI-S413 support USB connectivity?
No. The device does not include a USB PHY or USB controller. Communication is limited to I²C, SPI, UART, and CAN (via external transceiver). USB functionality requires an external bridge IC or migration to a PSoC™ 4 or 6 device with native USB support.
What development tools are officially supported for this part?
Infineon officially supports ModusToolbox™ (v3.x+) and legacy PSoC™ Creator (v4.4) for firmware development, CAPSENSE™ tuning, and hardware configuration. Both provide GUI-based peripheral setup, code generation, and debug via KitProg3 or MiniProg4 programmers.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No. The 12-bit SAR ADC has a single sample-and-hold circuit and sequences channels via hardware channel selector. True simultaneous sampling requires external parallel ADCs or devices with dual-SAR architectures like PSoC™ 6.
Is the 48LD TQFP package RoHS and REACH compliant?
Yes. CY8C4124AZI-S413 is manufactured in accordance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin finish and halogen-free molding compound per Infineon's material declarations.
