Product details
Overview
CY8C4244PVQ-442 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M0 programmable system-on-chip (PSoC® 4200 family) integrating MCU, reconfigurable analog/digital blocks, 12-bit 1-Msps SAR ADC, two opamps with comparator mode, and dual SCB peripherals supporting I²C/SPI/UART. It operates from 1.71 V to 5.5 V and delivers 48 MHz CPU performance with up to 32 kB flash and 4 kB SRAM. Used in capacitive touch HMI, motor control feedback, and low-power industrial sensor nodes.
For engineers reviewing the CY8C4244PVQ-442 datasheet, CY8C4244PVQ-442 pinout, CY8C4244PVQ-442 application, or CY8C4244PVQ-442 equivalent, key selection criteria include its 44-pin TQFP package, Deep Sleep current of 20 nA, CapSense Sigma-Delta (CSD) support with >5:1 SNR, and SWD debug interface compatibility with industry-standard tools.
Technical Context
The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, with dedicated clock gating for power management across five operating modes (Active, Sleep, Deep Sleep, Hibernate, Stop). Its analog subsystem includes a CTBm block hosting two opamps configurable as buffers, comparators, or ADC input drivers, plus a SAR ADC with hardware channel sequencer and signal averaging.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each containing eight macrocells and a data path, enabling custom logic synthesis or state machines. Two Serial Communication Blocks (SCBs) are fully reconfigurable at runtime between I²C, SPI, and UART protocols without firmware reload.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4245FNI-483 | 48-pin QFN, 64 kB flash, same core/peripherals - higher density flash and different package. | Requires PCB redesign for QFN layout; better suited for space-constrained designs needing larger code footprint. | Select when >32 kB flash is required and QFN thermal performance is preferred. |
| CY8C4247LQI-483 | 48-pin QFN, 128 kB flash, USB-capable SCB - adds USB 2.0 FS PHY and larger memory. | Enables direct USB HID/class-compliant device implementation; not pin-compatible with CY8C4244PVQ-442. | Choose only if native USB connectivity and >64 kB code space are mandatory design requirements. |
Compared with CY8C4245FNI-483 and CY8C4247LQI-483, CY8C4244PVQ-442 offers optimal balance of cost, 44-pin TQFP manufacturability, and sufficient resources for mid-tier embedded control-making it ideal for high-volume industrial HMI and sensor fusion applications where USB or extended flash are unnecessary.

FAQ
What is the maximum operating frequency of the Arm Cortex-M0 core in CY8C4244PVQ-442?
The CY8C4244PVQ-442 features an Arm Cortex-M0 CPU rated for up to 48 MHz operation. This frequency is achievable with the internal IMO (Internal Main Oscillator) or external crystal source, and the flash Read Accelerator ensures zero-wait-state execution at 24 MHz and one-wait-state performance at 48 MHz, maintaining deterministic real-time response.
Does CY8C4244PVQ-442 support capacitive touch sensing with water tolerance?
Yes. The device integrates CapSense Sigma-Delta (CSD) technology with hardware-based water rejection and >5:1 signal-to-noise ratio (SNR). Combined with SmartSense™ automatic tuning, it reliably detects finger touches even under moisture or with thin gloves-validated per Infineon's application notes AN88619 and AN79953 for industrial and medical HMI use cases.
Can the analog opamps be used for sensor signal conditioning?
Yes. The two programmable opamps support buffer, comparator, and transimpedance configurations. They can condition signals from resistive, capacitive, or current-output sensors-driving the 12-bit SAR ADC directly with selectable gain and bandwidth. Each opamp supports both high-drive external output and high-bandwidth internal routing, verified in the analog peripheral section of datasheet 001-87197.
Is SWD debug supported, and what are the requirements for secure firmware deployment?
Yes. CY8C4244PVQ-442 includes a 2-wire Serial Wire Debug (SWD) interface with four breakpoint and two watchpoint comparators. For secure deployment, flash protection modes (Open/Protected/Kill) are supported: Protected disables debug access until full flash erase; Kill permanently disables all debug and external erase-ensuring IP protection in production units per Infineon's PSoC 4 MCU Programming Specification.
