Product details
Overview
CY8C4013SXI-410T from Infineon (formerly Cypress) is a 32-bit Arm Cortex-M0 programmable system-on-chip (PSoC) with 16 KB flash, 2 KB SRAM, integrated CapSense sigma-delta capacitive sensing, two current DACs (IDACs), one low-power comparator, and one 16-bit TCPWM block. It operates from 1.71 V to 5.5 V and supports Deep Sleep wake-up via I²C address match or interrupt - used in touch-enabled human interface modules for industrial HMIs and consumer appliances.
For engineers reviewing the CY8C4013SXI-410T datasheet, CY8C4013SXI-410T pinout, CY8C4013SXI-410T application, or CY8C4013SXI-410T equivalent, key selection criteria include CapSense SNR performance, I²C wake capability in Deep Sleep, IDAC programmability for sensor biasing, and SWD debug interface compatibility with Arm toolchains.
Technical Context
The device implements a single-core Arm Cortex-M0 CPU running at up to 16 MHz with Thumb-2 instruction set support, nested vectored interrupt controller (NVIC) with eight interrupts, and Wakeup Interrupt Controller (WIC) for sub-35 µs Deep Sleep wake-up. Flash includes Read Accelerator enabling zero-wait-state access at full speed.
Analog subsystem integrates a 1.2-V internal reference, low-power comparator with fixed +input tied to reference and selectable −input from up to 16 GPIOs, and two programmable IDACs (±5% reference accuracy) supporting both general-purpose analog and CapSense electrode biasing - no external ADC required for basic capacitance measurement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 16 MHz max - enables binary-compatible migration to Cortex-M3/M4 and deterministic real-time control. |
| Flash Memory | 16 KB with Read Accelerator - delivers zero wait-state execution at full clock speed for deterministic firmware timing. |
| SRAM | 2 KB, zero wait-state - sufficient for real-time CapSense processing and small RTOS stacks without external memory. |
| CapSense Engine | Cypress CSD architecture with SmartSense auto-tuning (5–45 pF range) - eliminates manual calibration across production batches and environmental drift. |
| I²C Block | Multi-master SCB-I²C with Deep Sleep address detection - allows host MCU or PMIC to wake device without powering entire system. |
| Power Modes | Active / Sleep / Deep Sleep (35 µs wake latency) - supports battery-powered touch interfaces with multi-year shelf life. |
| Debug Interface | 2-wire Serial Wire Debug (SWD) - enables full on-chip debugging using standard Arm tools without JTAG pod or emulator. |
Pinout & Package
Package: 24-pin QFN (4 × 4 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary 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 | Digital and analog common return; must be low-impedance connection to PCB ground plane. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up enabled; resets CPU, peripherals, and configuration registers. |
| P0[0]–P0[7] | Programmable GPIO port | Supports CapSense, I²C SDA/SCL, TCPWM, comparator inputs, and configurable drive modes (strong, open-drain, high-Z). |
| P1[0]–P1[3] | Programmable GPIO port | CapSense-capable; usable as IDAC outputs or analog comparator inputs; supports slew-rate control for EMI reduction. |
| SWDCLK / SWDIO | Debug interface signals | 2-wire Serial Wire Debug; shared with GPIO P0[4]/P0[5]; no dedicated debug pins required. |
Key Features
| Feature | Design Value |
|---|---|
| CapSense Sigma-Delta (CSD) | Delivers >100 dB SNR and water-tolerant operation - enables reliable touch buttons/sliders in humid or wet environments without shielding. |
| SmartSense Auto-Tuning | Hardware-accelerated calibration over 5–45 pF sensor range - removes factory tuning step and compensates for aging, temperature, and contamination. |
| Deep Sleep I²C Address Match | Wakes CPU from 1.3 µA Deep Sleep state upon I²C bus activity targeting its address - eliminates polling and extends battery life in remote sensors. |
| Programmable IDACs | Two independent current sources (0–2 mA, ±5% accuracy) - directly bias CapSense electrodes or drive analog front-ends without external components. |
| SWD Debug on Production Silicon | Full debug visibility (breakpoints, watchpoints, memory inspection) using only SWDCLK/SWDIO pins - reduces test fixture complexity and enables field firmware updates. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G031K8T6 | ARM Cortex-M0+, 64 KB flash, no integrated CapSense; requires external touch controller or software-based capacitive sensing. | Lacks hardware-accelerated CSD engine and SmartSense - increases firmware complexity and reduces SNR in noisy environments. | Select when higher flash/RAM is needed and touch functionality is secondary or implemented externally. |
| MAX32620FTHR | ARM Cortex-M4F, 256 KB flash, integrated ADC/DAC but no dedicated CapSense block; uses software-based proximity sensing. | No hardware sigma-delta modulator - lower immunity to EMI and reduced water tolerance without custom analog front-end. | Select when floating-point math or advanced signal processing is required, and touch is simplified (e.g., proximity-only). |
Compared with STM32G031K8T6 and MAX32620FTHR, CY8C4013SXI-410T uniquely integrates production-ready CapSense with hardware auto-tuning and Deep Sleep I²C wake - reducing BOM count, firmware development time, and qualification effort for touch-centric designs.

FAQ
What is the maximum operating frequency of the CY8C4013SXI-410T CPU?
The Arm Cortex-M0 core runs at up to 16 MHz, supported by the internal main oscillator (IMO) trimmed to ±2% accuracy at 24 MHz and divisible down to 16 MHz. This frequency is guaranteed with zero wait-state flash access due to the integrated Read Accelerator, enabling deterministic real-time response for touch scanning and control loops.
Does CY8C4013SXI-410T support hardware-based capacitive touch sensing without external components?
Yes - it integrates Cypress's CapSense Sigma-Delta (CSD) engine with dedicated hardware modulators, IDACs, and SmartSense auto-tuning. No external RC networks, op-amps, or calibration resistors are required to implement robust touch buttons, sliders, or proximity sensors across production units and environmental conditions.
Can CY8C4013SXI-410T wake from Deep Sleep using I²C communication?
Yes - its SCB-I²C block supports address-match wake-up while in Deep Sleep mode drawing only 1.3 µA. When the bus transmits its 7-bit I²C address, the device wakes within 35 µs and resumes full operation, enabling ultra-low-power master-slave architectures without continuous polling.
Is SWD debug supported on the production CY8C4013SXI-410T silicon without special programming hardware?
Yes - Serial Wire Debug (SWD) is fully implemented in silicon and accessible via P0[4] (SWDCLK) and P0[5] (SWDIO). Standard Arm-compliant debug probes (e.g., Segger J-Link, ST-Link v2) can perform full read/write memory access, breakpoint setting, and real-time variable monitoring without requiring dedicated debug headers or factory programming.
