Product details
Overview
CY8C4025AZQ-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 system current, and features two reconfigurable serial communication blocks (SCBs) for I²C/SPI/UART. Used in touch-enabled human interface modules requiring low-power, high-SNR capacitive sensing and flexible peripheral routing.
For engineers reviewing the CY8C4025AZQ-S413 datasheet, CY8C4025AZQ-S413 pinout, CY8C4025AZQ-S413 application, or CY8C4025AZQ-S413 equivalent, this page delivers verified technical context, package mapping, GPIO configuration capability, TCPWM timing modes, and CAPSENSE™ sigma-delta SNR performance - all critical for embedded touch controller selection and firmware co-design.
Technical Context
The device implements a single-core Arm® Cortex®-M0+ CPU running at up to 48 MHz with single-cycle multiply and integrated read accelerator for flash access. Memory subsystem includes 32 KB of flash (with ECC support per TRM), 4 KB SRAM, and 8 KB ROM containing boot code and PDL routines.
Analog resources include a capacitive sigma-delta sensing block delivering >5:1 SNR and water tolerance, two programmable IDACs, and two low-power comparators operational in Deep Sleep. Digital peripherals comprise five 16-bit TCPWM blocks supporting center-aligned, edge-aligned, and pseudo-random PWM, plus two SCBs configurable as I²C, SPI, or UART with run-time reconfiguration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable MCU with integrated capacitive sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4025LQI-S403 | Same core and CAPSENSE™ engine, but in 32-pin QFN (5 mm × 5 mm); 28 GPIOs instead of 36 | Lower pin count limits multi-interface designs; no WCO pins onboard | Select when board space is constrained and full GPIO count not required |
| STM32G031K8T6 | No integrated CAPSENSE™; requires external RC network and firmware-based sensing; 64 MHz Cortex-M0+, 64 KB flash | Lacks hardware sigma-delta sensing - SNR typically ≤3:1 without extensive filtering | Choose only if touch performance requirements are relaxed and cost sensitivity outweighs design time savings |
Compared with CY8C4025LQI-S403, the CY8C4025AZQ-S413 offers 8 additional GPIOs and integrated WCO support for precise RTC; versus STM32G031K8T6, it delivers out-of-box CAPSENSE™ with >5:1 SNR and zero-touch firmware development overhead.

FAQ
Does CY8C4025AZQ-S413 support USB connectivity?
No. This device lacks a USB PHY or dedicated USB controller. Communication is limited to the two reconfigurable SCBs supporting I²C, SPI, and UART protocols. For USB host/device functionality, designers must use an external USB-to-UART bridge or select a PSoC™ 4100S or PSoC™ 6 variant with native USB support.
What is the maximum operating temperature for CY8C4025AZQ-S413?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient. Electrical specifications including flash write endurance, ADC accuracy, and TCPWM jitter are guaranteed across this range. Thermal derating is not required below 85 °C, and no external heatsink is needed in typical PCB layouts.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes. The CAPSENSE™ sigma-delta block remains active in Deep Sleep mode with 2.5 µA total system current. Touch detection events generate interrupts to wake the CPU, enabling ultra-low-power always-on user interfaces without sacrificing responsiveness.
Is ModusToolbox™ required to develop firmware for this MCU?
No. Firmware can be developed using PSoC™ Creator (Windows-only IDE) or Arm®-compliant toolchains like GCC + OpenOCD. ModusToolbox™ is optional but recommended for production projects due to its pre-validated CAPSENSE™ middleware, automated PDL configuration, and cross-platform project portability.
