Product details
Overview
CY8C4013SXI-411 from Infineon (formerly Cypress) is a 32-bit Arm Cortex-M0 programmable system-on-chip (PSoC) with integrated CapSense capacitive sensing, two IDACs, one low-power comparator, and a 16-bit TCPWM block. It features 16 KB flash, 2 KB SRAM, operates from 1.71–5.5 V, and supports Deep Sleep wake-up via I²C address match or interrupt - deployed in human-interface touch panels, smart home sensors, and battery-powered IoT edge nodes.
For engineers reviewing the CY8C4013SXI-411 datasheet, CY8C4013SXI-411 pinout, CY8C4013SXI-411 application, or CY8C4013SXI-411 equivalent, key selection criteria include CapSense SNR performance, SmartSense™ auto-tuning range (5–45 pF), I²C wake capability in Deep Sleep, TCPWM kill-signal triggering for motor control, and SWD debug interface compatibility with industry-standard Arm tools.
Technical Context
The CY8C4013SXI-411 implements a tightly coupled MCU subsystem with 16-MHz Arm Cortex-M0 core, 24-MHz IMO clock (±2% calibrated), and 40-kHz ILO for Deep Sleep timing. Its analog resources are purpose-built for capacitive sensing: the CSD block delivers high SNR and water tolerance, while the comparator uses a fixed 1.2-V internal reference and supports GPIO-configurable inputs.
Digital peripherals include a single multi-master I²C SCB block capable of address matching during Deep Sleep, one TCPWM block supporting center-aligned/edge/Pseudo-Random PWM modes, and programmable GPIO with configurable drive strength and slew rate across Ports 0–2. All routing is managed by PSoC Creator's automatic interconnect fabric.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 16 MHz max - enables Thumb-2 binary compatibility with Cortex-M3/M4 for scalable firmware migration. |
| Flash / SRAM | 16 KB flash with Read Accelerator, 2 KB zero-wait-state SRAM - supports real-time execution at full CPU speed without cache penalties. |
| CapSense | Cypress CSD engine with SmartSense™ auto-tuning (5–45 pF range) - eliminates manual sensor calibration in production environments. |
| I²C Block | Multi-master SCB with Deep Sleep address detection - allows wake-up from 35 µs Deep Sleep on targeted I²C slave address match. |
| TCPWM | 16-bit timer/counter/PWM with comparator-triggered kill signal - enables hardware-safe shutdown in motor control or power conversion. |
| Power Range | 1.71–5.5 V supply - supports direct connection to coin-cell, Li-ion, or regulated 3.3/5 V rails without external LDO. |
| Debug Interface | 2-wire Serial Wire Debug (SWD) - provides full on-chip debugging using standard Arm toolchains without emulator hardware. |
Pinout & Package
CY8C4013SXI-411 is housed in an 8-pin SOIC package (body width 3.9 mm, lead pitch 1.27 mm), optimized for space-constrained touch-enabled edge devices. Pin functions are fully reconfigurable via PSoC Creator; all GPIOs support CapSense, digital I/O, or analog input roles depending on runtime configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 1.71–5.5 V; powers all digital and analog blocks including CapSense modulator. |
| VSS | Ground reference | System return path; must be low-impedance for stable CapSense SNR and ADC accuracy. |
| XRES | Active-low external reset | Asynchronous reset input; internal pull-up ensures defined state when unconnected. |
| P0[0] | Programmable GPIO / CapSense input | Configurable as CSD electrode, digital I/O, or analog comparator input - no external components required for basic touch sensing. |
| P0[1] | Programmable GPIO / I²C SDA | Default I²C data line; retains function in Deep Sleep for wake-on-address-match operation. |
| P0[2] | Programmable GPIO / I²C SCL | Default I²C clock line; supports clock stretching and synchronized wake-up event generation. |
| P0[3] | Programmable GPIO / TCPWM output | Hardware PWM output pin; supports center-aligned mode for reduced EMI in motor drive applications. |
| SWDIO / SWCLK | Debug interface signals | Shared with P0[4]/P0[5]; enables in-system programming and full hardware debugging without dedicated debug header. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CapSense calibration over 5–45 pF sensor range - eliminates factory tuning fixtures and field recalibration. |
| Deep Sleep Wake Sources | I²C address match, GPIO interrupt, WDT timeout - enables sub-10 µA average current in battery-operated wake-and-sense cycles. |
| Configurable Drive Modes | Open-drain, strong, resistive pull-up/down, high-Z - allows precise signal integrity control for mixed-signal PCB layouts. |
| Integrated Voltage Reference | 1.2-V internal reference for comparator and ±5% IDAC reference - removes need for external precision references in cost-sensitive designs. |
| SWD Debug Security | Debug disable via firmware lock; flash protection with erase-all requirement for re-enable - prevents unauthorized firmware extraction in deployed devices. |
Applications
| Touch-Controlled Appliance Interface | Low-Power Industrial Sensor Node |
|---|---|
|
Use Scenario: Microwave oven or washing machine control panel with waterproof overlay and proximity wake-up. IC Role / Device Role / Timing Role: Primary MCU executing CapSense firmware, managing I²C display updates, and generating PWM for LED backlight dimming. Use Value: SmartSense™ maintains button responsiveness across temperature/humidity shifts; Deep Sleep draws <2 µA between touch events. |

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 |
|---|---|---|---|
| CY8C4014LQI-422 | 16-pin QFN, 32 KB flash, 4 KB SRAM, adds second TCPWM block and additional CapSense channels. | Required for designs needing >8 electrodes or dual independent PWM outputs (e.g., dual-motor control). | Select when higher memory, extra peripherals, or smaller footprint than SOIC are needed - not drop-in compatible due to pin count and package. |
| STM32G031F8P6 | ARM Cortex-M0+, 64 KB flash, 8 KB SRAM, no native CapSense - requires external RC network and firmware-based touch algorithm. | Suitable for cost-sensitive general-purpose MCU use where touch is secondary and SNR/water tolerance are non-critical. | Choose only if CapSense performance is not required and existing STM32 toolchain familiarity outweighs PSoC Creator's analog configurability. |
Compared with CY8C4013SXI-411, CY8C4014LQI-422 offers expanded memory and peripherals in a smaller package but lacks SOIC availability, while STM32G031F8P6 trades integrated CapSense for broader ecosystem support and higher memory - making CY8C4013SXI-411 optimal for compact, touch-first, ultra-low-power designs.

FAQ
Does CY8C4013SXI-411 support USB connectivity?
No, CY8C4013SXI-411 does not include a USB PHY or USB controller. It lacks dedicated USB transceivers, endpoint buffers, and USB protocol stack hardware. Communication is limited to I²C, GPIO-based bit-banged protocols, or external USB bridge ICs. USB functionality requires adding a companion chip such as CY7C65215 or CP2102N.
Can the internal comparator be used with external reference voltages?
No, the internal comparator exclusively uses the fixed 1.2-V internal reference connected to its positive input; the negative input accepts only GPIO-configurable signals. External reference injection is not supported. For variable-threshold sensing, designers must use IDACs to generate programmable bias voltages or implement ratiometric measurements using the IDAC-driven resistor ladder.
What is the maximum operating frequency of the TCPWM block?
The TCPWM block runs synchronously with the selected clock source, up to 16 MHz. When driven by the IMO (24 MHz), it operates at 16 MHz after division; its 16-bit counter supports resolution down to 62.5 ns per tick at 16 MHz, enabling precise PWM generation for motor control and LED dimming with sub-microsecond dead-time control.
Is PSoC Creator still actively supported for CY8C4013SXI-411 development?
Yes, PSoC Creator 4.4 remains the officially supported IDE for CY8C4013SXI-411. Infineon continues to provide maintenance releases, component library updates, and technical documentation through www.infineon.com. While ModusToolbox is recommended for newer PSoC 4100/6xxx families, PSoC Creator retains full build, debug, and CapSense tuning capability for the 4000 series.
