Product details
Overview
CY8C4025AZI-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 1.71–5.5 V and supports Deep Sleep mode at 2.5 µA digital current, targeting embedded human-interface and low-power industrial control applications.
For engineers reviewing the CY8C4025AZI-S413T datasheet, CY8C4025AZI-S413T pinout, CY8C4025AZI-S413T application, or CY8C4025AZI-S413T equivalent, key selection criteria include CAPSENSE™ SNR (>5:1), programmable analog (IDACs, comparators), reconfigurable digital logic, and dual SCB flexibility for mixed-protocol communication in space-constrained designs.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ core with a unified memory architecture, supported by a 32 kHz WCO and ±2% IMO clock source. Its analog subsystem includes a sigma-delta capacitive sensing engine and two low-power comparators operational in Deep Sleep mode.
Digital resources comprise two reconfigurable serial communication blocks (SCBs), five TCPWM units with center-aligned/PWM/kill-signal triggering, and programmable logic blocks enabling Boolean operations on GPIOs without firmware overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - enables real-time deterministic control with minimal latency in sensor fusion or motor timing loops. |
| Flash / SRAM | 32 KB flash with read accelerator / 4 KB SRAM - supports moderate firmware complexity including CAPSENSE™ tuning and protocol stacks without external memory. |
| CAPSENSE™ | Sigma-delta architecture with >5:1 SNR and SmartSense auto-tuning - delivers robust touch performance under moisture or EMI without manual calibration. |
| Serial Interfaces | 2 × SCBs, each configurable as I²C/SPI/UART - allows simultaneous use of different protocols (e.g., I²C for sensor hub + UART for debug) on shared pins. |
| TCPWM Blocks | 5 × 16-bit timer/counter/PWM units with comparator-triggered kill signals - supports precise motor phase control and safety-critical shutdown in BLDC drivers. |
| Power Modes | Deep Sleep at 2.5 µA digital current with active analog - enables battery-powered devices to maintain touch wake-up capability for months. |
| GPIO Count | Up to 36 programmable pins across 5 ports - any pin supports CAPSENSE™, analog input, or digital logic, simplifying PCB layout and routing. |
Pinout & Package
This device is packaged in a 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully reconfigurable via firmware, and all GPIOs support multiple roles including CAPSENSE™, analog, and digital I/O.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core & I/O supply | Accepts 1.71–5.5 V; powers digital logic, analog blocks, and GPIOs - enables single-rail operation across industrial and consumer voltage domains. |
| VSS | Digital ground | Primary reference for digital logic and SCB peripherals; must be low-impedance to minimize noise coupling into CAPSENSE™. |
| P0[0]–P0[7] | Programmable GPIO port | Supports CAPSENSE™ CSD, analog input, IDAC output, or digital logic - enables direct connection to touch buttons or sensor bridges without external components. |
| SWDCLK / SWDIO | Debug interface | Standard Arm® Serial Wire Debug pins - allow full in-system programming and real-time debugging using MiniProg4 or third-party SWD tools. |
| XRES | External reset | Active-low asynchronous reset input - provides hardware-level recovery path independent of internal power-on reset circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable SCBs | Each SCB dynamically switches between I²C, SPI, or UART at runtime - eliminates need for dedicated peripheral pins and reduces BOM count in multi-interface systems. |
| SmartSense Auto-Tuning | Firmware-free CAPSENSE™ calibration that adapts to environmental drift and parasitic capacitance - cuts development time for touch UIs by >70% versus manual tuning. |
| Deep Sleep Analog Operation | Low-power comparators and CAPSENSE™ sigma-delta engine remain active during 2.5 µA Deep Sleep - enables wake-on-touch with sub-millisecond response and no firmware intervention. |
| Programmable Logic Blocks | Boolean logic (AND/OR/XOR) applied directly to GPIO inputs/outputs in hardware - offloads simple state-machine tasks from CPU, reducing interrupt load and power consumption. |
Applications
| Home Appliance Control Panel | Industrial HMI Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4025LQI-S403 | Same core and peripherals, but in 40-pin QFN package with reduced GPIO count (28 pins) and no LCD drive capability. | Lacks LCD segment drive and has fewer GPIOs - suitable only when display integration is handled externally. | Select if board space is constrained and LCD functionality is unnecessary. |
| CY8C4127LQI-S433 | Higher-tier PSoC™ 4100S variant with 64 KB flash, 8 KB SRAM, USBFS block, and enhanced analog (12-bit SAR ADC). | Includes USB connectivity and higher-resolution ADC - adds cost and complexity where basic CAPSENSE™ and SCB functions suffice. | Choose only when USB host/device or precision analog acquisition is required. |
Compared with CY8C4025LQI-S403, the CY8C4025AZI-S413T offers more GPIOs and LCD drive for HMI consolidation; versus CY8C4127LQI-S433, it delivers optimal cost-performance balance for touch-centric, non-USB embedded control without over-specifying memory or analog resolution.

FAQ
What debug interfaces does CY8C4025AZI-S413T support?
The device uses standard Arm® Serial Wire Debug (SWD) with SWDCLK and SWDIO pins. It supports full in-circuit programming, real-time debugging, and trace via MiniProg4 or compatible third-party tools. Debug circuits are enabled by default but can be disabled in firmware for security-critical deployments.
Does CY8C4025AZI-S413T support USB connectivity?
No, this part lacks a USBFS block. USB functionality is available only in higher-tier PSoC™ 4100S and 4200S families. For USB-based designs, CY8C4127LQI-S433 or CY8C4247LQI-S483 are appropriate alternatives with integrated USB transceivers and PHY support.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes. The sigma-delta CAPSENSE™ engine and low-power comparators remain fully functional during Deep Sleep mode at 2.5 µA system current. Touch events generate interrupts to wake the CPU, enabling ultra-low-power wake-on-touch behavior without firmware polling.
What is the maximum operating frequency of the internal main oscillator (IMO)?
The internal main oscillator (IMO) is factory-trimmed to ±2% accuracy at 48 MHz and serves as the primary clock source for the Cortex®-M0+ core and most peripherals. It requires no external crystal and supports dynamic frequency scaling down to lower speeds for power optimization.
