Product details
Overview
CY8C4025LQI-S413T from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing, two SCBs supporting I²C/SPI/UART, and five 16-bit TCPWM blocks. It operates from 1.71 V to 5.5 V and supports Deep Sleep mode at 2.5 µA system current. Used in touch-enabled industrial HMI and smart appliance control.
For engineers reviewing the CY8C4025LQI-S413T datasheet, CY8C4025LQI-S413T pinout, CY8C4025LQI-S413T application, or CY8C4025LQI-S413T equivalent, key selection criteria include CAPSENSE™ SNR (>5:1), programmable analog (IDACs, low-power comparators), TCPWM kill-signal triggering, and 36-GPIO flexibility across QFN packages.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core with tightly coupled flash read accelerator and 8 KB ROM containing boot and PDL initialization code. System-level resources include SWD debug interface, NVIC with IRQMUX, and power management with IMO/ILO/WCO clock sources.
Analog subsystem includes a sigma-delta capacitive sensing engine (CAPSENSE™ v2) with hardware SmartSense tuning, two current DACs usable on any GPIO, and two deep-sleep-capable comparators. Digital fabric features five TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals for motor control safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time deterministic control with <100 ns interrupt latency |
| Memory | 32 KB flash + 4 KB SRAM - sufficient for CAPSENSE™ firmware, TCPWM control loops, and dual-SCB communication stacks |
| CAPSENSE™ | Sigma-delta architecture with >5:1 SNR and water tolerance - supports robust touch buttons/sliders in humid environments without shielding |
| TCPWM Blocks | 5 × 16-bit - provide independent PWM generation, quadrature decoding, and comparator-triggered fault shutdown for BLDC drives |
| SCBs | 2 × reconfigurable serial blocks - support concurrent I²C (sensor hub), SPI (display), and UART (debug) without external logic |
| GPIO | 36 pins, all CAPSENSE™/analog/digital capable - eliminates routing constraints in compact PCB layouts for touch + sensor + actuator integration |
| Power Modes | Deep Sleep @ 2.5 µA - sustains CAPSENSE™ wake-on-touch while preserving SRAM state for fast resume |
Pinout & Package
Package: 40-pin QFN (6 × 6 mm, 0.5 mm pitch), exposed thermal pad. Pin mapping validated per Infineon datasheet Rev. *Q (pp. 15–17).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Supports 1.71–5.5 V operation; VSS pins must be low-inductance connected to minimize noise in CAPSENSE™ and analog paths |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[3] | Programmable GPIO | All support CAPSENSE™, analog input/output, digital logic, and LCD segment drive - no fixed-function pin restrictions |
| SWDCLK, SWDIO | Debug interface | Standard Arm® Serial Wire Debug - enables full on-chip debugging without JTAG header; shares pins with GPIO P0[4]/P0[5] |
| XRES | External reset | Active-low asynchronous reset - required for reliable power-up sequencing and brown-out recovery |
| WCO_IN / WCO_OUT | 32.768 kHz crystal interface | Drives watch crystal for RTC and low-power timing - essential for Deep Sleep wake-up accuracy ±20 ppm |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual parameter adjustment and ensures consistent button response across temperature/humidity |
| Programmable IDACs | Two current sources configurable per-pin (0.1–8 mA) - enable direct-drive of capacitive sensors or analog front-end biasing without external components |
| Comparator-triggered TCPWM kill | Digital fault path from comparator output to TCPWM block - achieves <1 µs shutdown for overcurrent/overvoltage protection in motor control |
| Reconfigurable SCBs | Each SCB dynamically switches between I²C master/slave, SPI master/slave, or UART TX/RX - reduces BOM count in multi-interface systems |
| GPIO drive strength/slew control | Configurable per-pin (2–12 mA, slow/fast slew) - suppresses EMI in noisy industrial environments while maintaining signal integrity |
Applications
| Industrial HMI Panels | Smart Home Appliances |
|---|---|

| Medical Patient Monitors | IoT Edge Sensor Nodes |
Use Scenario: Portable vital sign monitor with touch interface, LED indicators, and analog sensor signal conditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4025LQI-S403T | Same die, 24-pin QFN package (fewer GPIOs, no WCO pins) | Limited to space-constrained designs without RTC or low-power wake-on-crystal requirements | Select when footprint and cost priority outweigh CAPSENSE™ channel count and RTC needs |
| CY8C4014LQI-S412T | Same family, 16 KB flash / 2 KB SRAM, no CAPSENSE™ v2 engine | Suitable for non-touch applications requiring basic PWM and communication only | Choose when touch interface is unnecessary and BOM cost reduction is critical |
Compared with CY8C4025LQI-S413T, the S403T sacrifices GPIO count and RTC capability for smaller size, while the S412T removes CAPSENSE™ and half the memory - both require firmware and layout changes, and neither supports SmartSense or sigma-delta sensing.

FAQ
What development tools are supported for CY8C4025LQI-S413T?
Infineon officially supports ModusToolbox™ (cross-platform, Eclipse-based) and PSoC™ Creator (Windows-only, schematic-driven). Both include CAPSENSE™ Tuner, TCPWM configurator, and peripheral driver libraries. MiniProg4 programmer/debugger is required for firmware flashing and SWD debugging.
Does CY8C4025LQI-S413T support hardware encryption or secure boot?
No. This device lacks dedicated cryptographic accelerators or immutable boot ROM. Flash protection bits prevent unauthorized readout, but secure boot, AES, or SHA functions are not implemented in silicon. For security-critical applications, consider PSoC™ 6 series devices.
Can all 36 GPIOs be used simultaneously for CAPSENSE™?
No. While all GPIOs are CAPSENSE™-capable, the CAPSENSE™ v2 block supports up to 32 sensing channels (electrodes) per device. Simultaneous use of all 36 pins requires allocation of some pins to digital or analog functions outside CAPSENSE™, such as SCB or TCPWM signals.
Is the WCO (32.768 kHz crystal oscillator) mandatory for operation?
No. The WCO is optional and only required for precise RTC timing or Deep Sleep wake-up intervals below 1 second. Internal ILO (32 kHz) suffices for coarse timing, but its ±50% accuracy makes it unsuitable for timekeeping or low-jitter wake events.
