Product details
Overview
CY8C4024PVA-S412T from Infineon is an AEC-Q100 qualified automotive-grade PSoC™ 4000S microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing with >5:1 SNR, two low-power comparators, and two IDACs - deployed in motor control interfaces and touch-enabled automotive cabin modules.
For engineers reviewing the CY8C4024PVA-S412T datasheet, CY8C4024PVA-S412T pinout, CY8C4024PVA-S412T application, or CY8C4024PVA-S412T equivalent, key selection criteria include AEC-Q100 S-grade (–40°C to +105°C), Deep Sleep current of 2.5 µA, reconfigurable SCB blocks for I²C/SPI/UART, TCPWM kill-signal triggering, and GPIO-capable LCD segment drive.
Technical Context
The device implements a tightly coupled system-on-chip architecture where the Cortex-M0+ core interfaces via AHB-Lite to programmable analog (CSD, LP comparators, IDACs) and digital blocks (TCPWM, SCB, PLD). Clocking relies on IMO (internal main oscillator), ILO (low-speed), and optional WCO for precision timing.
Capacitive sensing uses sigma-delta modulation with hardware-accelerated smart tuning; serial communication is handled by two fully reconfigurable SCBs supporting runtime mode switching between I²C, SPI, and UART protocols without firmware reload.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4024LQI-S403T | Same PSoC™ 4000S core but 32-pin QFN; lacks LCD drive capability; rated for E-grade (–40°C to +125°C). | Targeted at under-hood applications requiring higher temperature rating but no display integration. | Select when extended temperature range is critical and LCD functionality is unused. |
| STM32G071CBT6 | Arm® Cortex®-M0+ at 64 MHz; 128 KB flash, 36 KB SRAM; no integrated CAPSENSE™ or programmable analog blocks. | Requires external touch controller and signal conditioning ICs for equivalent capacitive sensing performance. | Select when high code density and peripheral count outweigh integrated analog flexibility. |
Compared with CY8C4024LQI-S403T and STM32G071CBT6, the CY8C4024PVA-S412T uniquely integrates CAPSENSE™, programmable analog, and LCD drive in a compact 24-pin QFN - reducing component count and PCB area in space-constrained automotive HMI designs.

FAQ
Is CY8C4024PVA-S412T qualified for automotive use?
Yes. It is AEC-Q100 qualified for S-grade (–40°C to +105°C), with full documentation including stress test reports, failure-in-time (FIT) data, and PPAP-ready packaging. It meets automotive reliability and qualification requirements for cabin electronics, not under-hood applications.
Does this part support hardware debugging in production systems?
Yes. It features Arm® Serial Wire Debug (SWD) with full on-chip debug capability - allowing real-time firmware inspection, breakpoint setting, and memory access without external emulators or special debug interfaces, even in final vehicle assemblies.
Can all GPIO pins be used for CAPSENSE™ simultaneously?
Yes. All 34 GPIOs support CAPSENSE™ CSD functionality, though practical simultaneous usage depends on mutual capacitance coupling and layout. The hardware engine handles scanning, baseline tracking, and noise filtering without CPU intervention.
What is the maximum operating frequency of the internal main oscillator (IMO)?
The IMO is factory-trimmed to 48 MHz with ±2% accuracy over temperature and voltage. It serves as the default system clock source and can be used directly for CPU, TCPWM, and SCB operation without external crystal loading.
