Product details
Overview
CY8C4244PVA-442T from Infineon is an AEC-Q100 qualified 32-bit Arm® Cortex®-M0 microcontroller with 32 kB flash, 4 kB SRAM, and integrated programmable analog/digital blocks for capacitive sensing, 12-bit SAR ADC (1 Msps), and dual SCB peripherals supporting I²C/SPI/UART/LIN. It operates from 1.71 V to 5.5 V and delivers up to 48 MHz performance in automotive body control modules.
For engineers reviewing the CY8C4244PVA-442T datasheet, CY8C4244PVA-442T pinout, CY8C4244PVA-442T application, or CY8C4244PVA-442T equivalent, key selection criteria include AEC-Q100 qualification, on-chip CSD-based touch sensing capability, dual reconfigurable serial communication blocks, and Deep Sleep operation with two low-power comparators and LCD segment drive support.
Technical Context
The device integrates a 48 MHz Arm Cortex-M0 CPU with single-cycle multiply, flash Read Accelerator, and SROM boot code. Its system-level resources include IMO (4–48 MHz) and ILO (32.768 kHz) clock sources, Power-on-Reset with Brown-Out detection, and SWD debug interface.
Analog subsystem comprises one opamp with comparator mode and ADC input buffering, two IDACs for CSD or general-purpose use, two low-power comparators active in Deep Sleep, and a 12-bit SAR ADC with channel sequencer and signal averaging. Digital subsystem includes four UDBs (8 macrocells each), four TCPWM blocks, and two SCBs supporting runtime-reconfigurable protocols.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive-grade microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4245FNI-483 | Same PSoC 4200 family, 48-pin WLCSP package, 64 kB flash, 8 kB SRAM - higher memory density but no exposed thermal pad. | Preferred for ultra-compact modules where board area is constrained and thermal load is lower. | Select when firmware complexity demands >32 kB flash and PCB real estate limits QFN use. |
| SPC560B50L3 | 32-bit Power Architecture e200z0 core, 512 kB flash, 40 kB RAM, ASIL-B ready - lacks integrated CAPSENSE™ and programmable analog blocks. | Suitable for safety-critical powertrain functions requiring ISO 26262 compliance beyond AEC-Q100 Grade 2. | Choose when functional safety certification (ASIL-B) and large code footprint outweigh need for on-die capacitive sensing. |
Compared with CY8C4244PVA-442T, CY8C4245FNI-483 offers greater memory headroom in a smaller footprint but reduced thermal performance, while SPC560B50L3 provides higher safety assurance and larger memory at the cost of analog programmability and touch integration.

FAQ
Does CY8C4244PVA-442T support CAN communication?
No. The CY8C4244PVA-442T does not integrate a CAN controller or physical layer. It supports LIN Slave 2.1/2.2, I²C, SPI, and UART via its two SCB peripherals. CAN functionality requires external transceivers and software stack implementation on UART or dedicated CAN MCU families like Infineon's AURIX™ or TRAVEO™.
What development tools are officially supported for this device?
Infineon officially supports PSoC™ Creator IDE (legacy) and ModusToolbox™ for CY8C4244PVA-442T. Both provide CAPSENSE™ Tuner, TCPWM configurator, SCB protocol wizards, and debug integration with KitProg3. Hardware evaluation platforms include CY8CKIT-042-BLE and CY8CKIT-044.
Is the internal temperature sensor calibrated across the full −40 °C to +105 °C range?
Yes. The on-die temperature sensor is factory-calibrated and specified over the full AEC-Q100 Grade 2 range (−40 °C to +105 °C), with ±3 °C accuracy. Calibration data is stored in SROM and automatically applied during ADC conversion in temperature-sensing mode.
Can all 24 GPIOs be used simultaneously for CAPSENSE™ electrodes?
No. While 24 GPIOs are programmable, CAPSENSE™ CSD supports up to 32 electrodes but requires dedicated routing resources and shared analog muxing. Practical electrode count depends on scan speed and SNR requirements; typical designs use 12–20 electrodes with guard sensors and shield traces implemented on selected pins.
