Product details
Overview
CY8C4244PVA-442 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. It delivers 48 MHz CPU performance, 12-bit 1-Msps SAR ADC, two opamps with comparator mode, and capacitive sensing (CSD) for automotive-grade human interface applications including touch buttons and sliders in harsh environments.
For engineers reviewing the CY8C4244PVA-442 datasheet, CY8C4244PVA-442 pinout, CY8C4244PVA-442 application, or CY8C4244PVA-442 equivalent, this part supports reconfigurable mixed-signal design, deep-sleep operation with active comparators, hardware-accelerated CAPSENSE™, and dual SCB peripherals for I²C/SPI/UART/LIN - critical for automotive body control, industrial HMI, and battery-powered embedded systems.
Technical Context
The CY8C4244PVA-442 implements a tightly coupled MCU subsystem with single-cycle multiply and Read Accelerator for deterministic flash execution. Its analog subsystem includes one opamp supporting ADC input buffering and comparator mode, plus two low-power comparators that remain active in Deep Sleep - enabling wake-on-event functionality without CPU intervention.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and data path, allowing custom logic synthesis. Two reconfigurable Serial Communication Blocks (SCBs) support runtime switching between I²C, SPI, UART, and LIN Slave 1.3/2.1 protocols - eliminating need for external protocol translators in multi-interface automotive nodes.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KB6 | ARM Cortex-M4F @ 170 MHz, 12-bit 2.4 Msps ADC, no integrated CAPSENSE™ - requires external touch controller for comparable HMI functionality. | Targets higher-performance motor control with FPU; lacks automotive-qualified capacitive sensing IP and AEC-Q100 Grade 2 rating. | Select when floating-point math or higher ADC throughput is required, and touch is implemented externally via I²C. |
| TI MSP430FR2633 | MSP430 core @ 16 MHz, FRAM memory, integrated CapTIvate™, but no ARM architecture or 48 MHz performance - limited real-time OS compatibility. | Focused on ultra-low-power (<1 µA deep sleep) touch-only applications; lacks TCPWM flexibility and SCB protocol agility. | Select for battery-powered remote controls where sub-µA sleep current outweighs processing needs and protocol diversity. |
