Product details
Overview
CY8C4013SXI-400T from Infineon (formerly Cypress) is a 32-bit programmable system-on-chip (PSoC® 4000 family) MCU featuring an Arm® Cortex®-M0 CPU running at 16 MHz, 16 KB flash with Read Accelerator, 2 KB SRAM, integrated CapSense® sigma-delta capacitive sensing, one low-power comparator with 1.2-V internal reference, and one 16-bit TCPWM block. It targets compact embedded systems requiring touch interfaces, low-power operation, and mixed-signal integration - such as smart home sensors and portable medical devices.
For engineers reviewing the CY8C4013SXI-400T datasheet, CY8C4013SXI-400T pinout, CY8C4013SXI-400T application, or CY8C4013SXI-400T equivalent, key selection criteria include its 8-pin SOIC package, Deep Sleep wake-up on I²C address match, SmartSense™ auto-tuning for 5–45 pF sensor range, and SWD debug interface compatibility with industry-standard Arm tools.
Technical Context
The device implements a tightly coupled MCU subsystem with clock-gated CPU in Sleep mode and full subsystem shutdown in Deep Sleep (35 µs wake-up). 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 any of 16 GPIO pins as input.
Digital peripherals are minimal but targeted: a single multi-mode TCPWM supports center-aligned/edge/Pseudo-Random PWM for motor control or timing, and the SCB-I²C block enables multi-master communication with Deep Sleep address detection and wake-up - eliminating need for external interrupt controllers in battery-powered nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 16 MHz max - enables Thumb-2 binary compatibility with higher Cortex-M families for scalable firmware. |
| Flash / SRAM | 16 KB flash with Read Accelerator + 2 KB zero-wait-state SRAM - supports real-time code execution without performance penalty at full speed. |
| Capacitive Sensing | Cypress CapSense Sigma-Delta (CSD) with SmartSense™ auto-tuning - eliminates manual calibration across 5–45 pF sensor range and maintains reliability under moisture. |
| Low-Power Mode | Deep Sleep with I²C address-match wake-up - allows continuous bus monitoring at sub-µA current, ideal for always-on touch interfaces. |
| Comparator | Single low-power comparator with fixed 1.2-V internal reference - provides threshold detection without external components or supply dependency. |
| Debug Interface | Serial Wire Debug (SWD), 2-wire JTAG-compatible - enables full on-chip debugging using standard Arm toolchains without debug pods or emulators. |
| Supply Range | 1.71 V to 5.5 V - supports direct connection to Li-ion, coin cell, or 3.3/5 V rails without LDO pre-regulation. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), body width 3.9 mm, lead pitch 1.27 mm, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Main supply rail (1.71–5.5 V); powers all digital and analog blocks including CapSense modulator. |
| VSS | Ground reference | System ground return for all circuits; must be low-impedance for stable CapSense SNR. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up enabled; resets CPU, peripherals, and memory state. |
| P0[0] | Programmable GPIO / CapSense input | Configurable as general-purpose I/O or dedicated CapSense electrode; supports shield and sensor routing. |
| P0[1] | Programmable GPIO / CapSense input | Second CapSense electrode; shares same CSD hardware resource as P0[0]; supports mutual-capacitance layouts. |
| SCL | I²C clock line | Open-drain bidirectional clock; supports multi-master arbitration and Deep Sleep wake-up on address match. |
| SDA | I²C data line | Open-drain bidirectional data; retains bus state during Deep Sleep and triggers wake on valid address sequence. |
| SWDIO / SWCLK | Debug interface signals | Shared with GPIO P0[4]/P0[5]; enables programming and full-chip debug without dedicated debug header. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated calibration of CapSense parameters across temperature and humidity - removes firmware tuning overhead and ensures consistent button response over life. |
| Deep Sleep I²C Wake-Up | SCB-I²C block remains active at <1 µA while monitoring bus for assigned 7-bit address - enables ultra-low-power touch hubs in IoT edge nodes. |
| Programmable Drive Modes | Each GPIO supports multiple drive strengths (0.5–10 mA), slew rates (slow/fast), and configurations (pull-up/down, open-drain) - simplifies interface to diverse sensors and actuators without external logic. |
| Integrated Voltage Reference | Stable 1.2-V internal reference for comparator and IDACs - eliminates need for precision external references in threshold-detection and sensor-biasing applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4014LQI-400T | Same PSoC 4000 family, 16-pin QFN package, adds second TCPWM block and 4 additional GPIOs. | Required when >2 PWM outputs or >8 GPIOs needed; lacks SOIC package for through-hole prototyping. | Select if board space allows QFN and design requires dual PWM or expanded I/O without redesigning layout. |
| STM32F031K4T6 | Arm Cortex-M0, 48 MHz, 16 KB flash, no integrated CapSense; requires external touch controller or software-based capacitance measurement. | Suitable for cost-sensitive non-touch applications; touch functionality must be added externally with higher BOM and firmware complexity. | Choose only if CapSense is unnecessary and higher CPU clock (48 MHz) justifies loss of analog integration and increased component count. |
Compared with CY8C4013SXI-400T, CY8C4014LQI-400T offers more I/O and peripherals in a smaller footprint but sacrifices through-hole assembly; STM32F031K4T6 delivers higher CPU throughput but forces external implementation of capacitive sensing, increasing design time and failure modes in moisture-prone environments.

FAQ
Does CY8C4013SXI-400T support USB or Bluetooth connectivity?
No. This device lacks native USB or Bluetooth PHYs. Communication is limited to I²C, and it requires external transceivers or companion radios (e.g., BLE modules connected via I²C or UART) for wireless protocols. Its design focus is ultra-low-power capacitive sensing and local control-not RF stack integration.
Can the internal comparator be used with external reference voltages?
No. The comparator uses only the fixed 1.2-V internal reference; its positive input is hardwired to this reference, and no external reference input pin or configuration option exists. For variable thresholds, use the IDACs to generate bias currents or implement software-based comparison using ADC readings from other devices.
What is the maximum operating frequency of the TCPWM block?
The TCPWM block runs synchronously with the CPU clock (FCPU), supporting up to 16 MHz input. Its counter resolution is 16-bit, enabling precise PWM generation down to ~1.5 Hz at 16 MHz, or sub-nanosecond edge placement accuracy in high-frequency modes - critical for motor gate drive timing and LED dimming fidelity.
Is SmartSense™ tuning compatible with custom PCB layouts and non-standard electrode geometries?
Yes. SmartSense™ operates entirely in hardware and adapts to parasitic capacitance, trace length, overlay thickness, and electrode shape. It has been validated across flex circuits, rigid FR4, and hybrid sensor stacks - provided the electrode connects directly to P0[0] or P0[1] and shares the same ground plane as VSS.
