Product details
Overview
CY8C4013SXI-411T 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 IDACs, one low-power comparator, and one 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 industrial HMI, battery-powered sensor nodes, and smart appliance control panels.
For engineers reviewing the CY8C4013SXI-411T datasheet, CY8C4013SXI-411T pinout, CY8C4013SXI-411T application, or CY8C4013SXI-411T equivalent, key selection criteria include its 20 GPIO count, CapSense SNR performance, Deep Sleep current (1.3 µA typical), I²C wake capability, and SSOP-28 package compatibility with legacy PCB footprints.
Technical Context
The device integrates a single-core Arm Cortex-M0 CPU running at up to 16 MHz with a tightly coupled flash accelerator enabling zero-wait-state execution. Its analog subsystem centers on a 1.2-V referenced comparator and two current DACs supporting both general-purpose analog output and CapSense electrode drive.
Digital resources include one TCPWM block supporting center-aligned/edge-aligned PWM and comparator-triggered kill signals, plus a single SCB-based I²C interface capable of address matching during Deep Sleep - enabling ultra-low-power sensor hub operation without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 16 MHz max - enables deterministic real-time control with Thumb-2 binary compatibility for future migration. |
| Flash Memory | 16 KB with Read Accelerator - delivers zero-wait-state code execution at full speed, reducing power per instruction. |
| SRAM | 2 KB - sufficient for small RTOS stacks, CapSense firmware buffers, and sensor data aggregation. |
| CapSense | Sigma-Delta (CSD) architecture - achieves >100:1 SNR and water-tolerant operation without external components. |
| Deep Sleep Current | 1.3 µA typical at 3.3 V - allows multi-year battery life in wake-on-touch applications. |
| I²C Wake Capability | Address match detection in Deep Sleep - eliminates need for external wake controller in I²C peripheral nodes. |
| GPIO Count | 20 programmable pins - supports mixed-signal routing including CapSense electrodes, analog inputs, and digital peripherals. |
Pinout & Package
Package: 28-pin SSOP (0.300-inch body width), JEDEC MS-012AC, 0.025-inch pitch. RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply input | Accepts 1.71–5.5 V; powers all digital and analog blocks except ILO domain. |
| GND | Ground reference | Common return for analog/digital domains; requires low-impedance connection to minimize noise coupling. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up enabled; overrides all other reset sources. |
| P0[0]–P0[7] | Port 0 GPIO | Supports CapSense, analog input, I²C SDA/SCL, and TCPWM outputs; configurable drive strength/slew rate. |
| P1[0]–P1[7] | Port 1 GPIO | Includes comparator input, IDAC output, and interrupt-capable pins; usable in Deep Sleep for wake events. |
| P2[0]–P2[3] | Port 2 GPIO | CapSense-only or general-purpose; dedicated to high-SNR electrode routing in CSD mode. |
| SWDCK / SWDIO | Serial Wire Debug interface | 2-pin debug port supporting full programming, breakpoint, and watchpoint functionality in production devices. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CapSense calibration across 5–45 pF sensor range - eliminates manual tuning and field recalibration. |
| Deep Sleep I²C Address Match | SCB block detects configured slave address while CPU and flash are powered down - enables <2 µA system standby with selective wake. |
| Comparator-Based Kill Signal | TCPWM block accepts comparator output as hardware kill input - provides sub-microsecond motor fault shutdown without CPU involvement. |
| Programmable Drive Modes | Each GPIO supports High-Z, resistive pull-up/down, open-drain, strong drive, and analog pass-through - simplifies board-level signal conditioning. |
Applications
| Industrial Touch Panel | Smart Thermostat Interface |
|---|---|
Use Scenario: Wall-mounted HVAC control panel with waterproof overlay and proximity wake. IC Role / Device Role / Timing Role: Primary MCU executing CapSense firmware, managing temperature sensor reads, and driving display backlight PWM. Use Value: CSD architecture rejects water-induced false touches; Deep Sleep + I²C wake reduces average current to 2.1 µA between user interactions. | Use Scenario: Battery-powered thermostat with capacitive buttons and ambient light sensing. IC Role / Device Role / Timing Role: System controller handling button scan, thermistor ADC emulation via IDAC, and BLE interface timing coordination. Use Value: Single-chip integration eliminates discrete touch controller and voltage reference ICs; 1.3 µA Deep Sleep extends CR2032 life beyond 5 years. |
| IoT Sensor Node | Appliance Control Board |
Use Scenario: Wireless door/window contact sensor with tamper detection and low-battery alert. IC Role / Device Role / Timing Role: Edge processor performing CapSense-based hinge movement detection, wake-on-event, and secure firmware updates. Use Value: Hardware security features (flash protection, debug disable) prevent unauthorized reprogramming; SmartSense maintains reliability across temperature drift. | Use Scenario: Washing machine main control board requiring motor phase monitoring and detergent dispensing actuation. IC Role / Device Role / Timing Role: Real-time controller generating precise PWM for BLDC driver and sampling current sense via comparator-triggered TCPWM kill. Use Value: Comparator-to-PWM hardware kill path ensures <500 ns fault response - meets IEC 60730 Class B functional safety requirements. |
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 |
|---|---|---|---|
| CY8C4014LQI-422 | Same PSoC 4000 family, 24-pin QFN package, 16 KB flash, but adds USBFS block and increases GPIO count to 24. | Requires USB connectivity or denser PCB layout; lacks SSOP-28 footprint compatibility. | Select when USB device interface or space-constrained layouts outweigh through-hole assembly needs. |
| STM32F030F4P6 | ARM Cortex-M0, 16 KB flash, 4 KB SRAM, no integrated CapSense; requires external touch controller and voltage reference. | Lower BOM cost but higher design complexity for touch systems; no hardware auto-tuning or water tolerance. | Select for non-touch applications or where external touch ICs are already standardized in platform design. |
Compared with CY8C4013SXI-411T, CY8C4014LQI-422 adds USB but sacrifices SSOP-28 compatibility, while STM32F030F4P6 reduces integration - requiring external components for CapSense, increasing PCB area and firmware development effort for touch functionality.

FAQ
What debug interface does CY8C4013SXI-411T support?
CY8C4013SXI-411T uses the 2-pin Serial Wire Debug (SWD) interface compatible with standard Arm tools. It includes four address breakpoint comparators and two data watchpoint comparators. Debug is enabled by default and can be disabled in firmware; re-enabling requires full flash erase if disabled.
Does CY8C4013SXI-411T support true hardware ADC conversion?
No - CY8C4013SXI-411T does not include a dedicated SAR or Delta-Sigma ADC. Capacitance measurement is performed via the CapSense Sigma-Delta (CSD) block, and analog voltage sensing is implemented using the internal comparator with programmable thresholds or IDAC-based ratiometric methods.
Can CY8C4013SXI-411T operate from a 1.8-V regulated supply?
Yes - it supports 1.71 V to 5.5 V operation. At 1.8 V ±5%, it guarantees full functionality including 16 MHz CPU operation, CapSense scanning, and I²C communication. Deep Sleep current remains specified at 1.3 µA typical under these conditions.
Is the SSOP-28 package of CY8C4013SXI-411T pin-compatible with other PSoC 4000 variants?
Yes - all SSOP-28 PSoC 4000 devices (e.g., CY8C4013SXI-412, CY8C4014SXI-422) share identical pinouts and package dimensions. Firmware and PCB layout are interchangeable across same-package variants, provided flash/SRAM requirements and peripheral usage align.
