Product details
Overview
CY8C4025LQI-S413 from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller with 32 KB flash, 4 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It operates from 1.71 V to 5.5 V, supports Deep Sleep mode at 2.5 µA, and delivers best-in-class SNR (>5:1) for water-tolerant touch interfaces in consumer HMI and industrial control panels.
For engineers reviewing the CY8C4025LQI-S413 datasheet, CY8C4025LQI-S413 pinout, CY8C4025LQI-S413 application, or CY8C4025LQI-S413 equivalent, key selection criteria include its reconfigurable analog/digital blocks, dual SCB serial interfaces (I²C/SPI/UART), five TCPWM timers with comparator-triggered kill signals, and SmartSense™ automatic hardware tuning for production-ready touch design.
Technical Context
The device integrates a single-cycle multiply Arm® Cortex®-M0+ CPU running at up to 48 MHz, coupled with programmable analog blocks including two low-power comparators active in Deep Sleep and a sigma-delta CAPSENSE™ engine. Its digital subsystem includes five 16-bit TCPWM blocks supporting center-aligned PWM and hardware kill signal generation for motor control safety.
Two reconfigurable Serial Communication Blocks (SCBs) provide runtime-selectable I²C, SPI, or UART functionality, while the I/O Subsystem enables any of its 36 GPIOs to serve as CAPSENSE™, analog input, or digital port with programmable drive strength and slew rate - all routed via a high-flexibility interconnect matrix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max, single-cycle multiply - enables real-time firmware execution with deterministic interrupt latency for responsive HMI and control loops. |
| Memory | 32 KB flash with read accelerator + 4 KB SRAM - sufficient for CAPSENSE™ firmware, communication stacks, and small RTOS deployments without external memory. |
| Capacitive Sensing | Sigma-delta CAPSENSE™ v2 with >5:1 SNR and SmartSense™ auto-tuning - eliminates manual calibration effort and ensures robust operation under moisture or EMI stress. |
| Low-Power Modes | Deep Sleep mode draws 2.5 µA digital system current with analog peripherals operational - extends battery life in portable touch-enabled devices. |
