Product details
Overview
CY8C4244PVA-442Z from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M0 programmable system-on-chip (PSoC® 4100 family) featuring 32 kB flash, 4 kB SRAM, 12-bit 806 ksps SAR ADC, two opamps with comparator mode, and two low-power comparators. It operates from 1.71 V to 5.5 V and supports Hibernate/Deep Sleep modes with 20-nA Stop Mode current. Used in capacitive touch HMI, industrial sensor nodes, and motor control interfaces.
For engineers reviewing the CY8C4244PVA-442Z datasheet, CY8C4244PVA-442Z pinout, CY8C4244PVA-442Z application, or CY8C4244PVA-442Z equivalent, key selection criteria include its reconfigurable analog/digital blocks, CapSense® Sigma-Delta (CSD) support with >5:1 SNR, 48-pin TQFP package, and SWD debug interface compatibility with Arm industry-standard tools.
Technical Context
The device integrates a single-cycle multiply Arm Cortex-M0 CPU running at up to 24 MHz, coupled with a programmable analog subsystem including two opamps (with ADC input buffering and comparator modes) and a 12-bit SAR ADC with channel sequencer and signal averaging. Its digital fabric includes four 16-bit TCPWM blocks supporting center-aligned, edge-aligned, and pseudo-random PWM generation.
Two reconfigurable Serial Communication Blocks (SCBs) provide runtime-selectable I²C, SPI, or UART functionality, while five power modes-Active, Sleep, Deep Sleep, Hibernate, and Stop-are managed by the PWRSYS block with brown-out detect (BOD), low-voltage detect (LVD), and internal oscillators (IMO/ILO). GPIOs support CapSense®, LCD drive, and programmable drive strength/slew rate on all 36 pins.

IC Role / Device Role / Timing Role: System controller managing sensor polling, SAR ADC acquisition, low-power sleep scheduling, and SCB-configured I²C master interface. Use Value: 20-nA Stop Mode and hardware sequenced ADC sampling reduce average current to <1 µA during idle, extending coin-cell life beyond 5 years. |
| Motor Control Interfaces | Medical Diagnostic Handhelds |
Use Scenario: Compact BLDC motor driver board requiring PWM generation, current sensing, and fault protection logic. IC Role / Device Role / Timing Role: Real-time controller generating center-aligned PWM via TCPWM blocks, reading shunt voltage via SAR ADC, and triggering kill signals via comparator outputs. Use Value: Comparator-based hardware kill signal propagation (<100 ns latency) ensures immediate gate shutdown during overcurrent, meeting IEC 61800-5-2 functional safety requirements. | Use Scenario: Portable ECG/SpO₂ device requiring analog front-end signal conditioning, low-noise ADC sampling, and USB HID communication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4245FNI-483 | 48-ball WLCSP package, I²C bootloader pre-programmed, no external crystal required (uses IMO only) | Better suited for space-constrained wearables; lacks XTAL_IN/XTAL_OUT pins and has reduced GPIO count (28 vs 36) | Select when board area < 4 mm² and crystal-free operation is acceptable |
| STM32F072RBT6 | ARM Cortex-M0+, 48 MHz, 128 kB flash, but fixed-function analog (no reconfigurable opamps or CapSense®) | Requires external touch controller and opamp circuitry for equivalent analog capability; higher flash but less analog flexibility | Select when deterministic 48 MHz timing and larger code footprint outweigh need for on-die programmable analog |
Compared with CY8C4244PVA-442Z, CY8C4245FNI-483 trades package size and bootloader convenience for reduced I/O and clocking flexibility, while STM32F072RBT6 offers higher CPU speed and flash but demands external analog components - making CY8C4244PVA-442Z optimal for designs prioritizing analog integration and rapid capacitive HMI prototyping.

FAQ
What debug interface does CY8C4244PVA-442Z support?
CY8C4244PVA-442Z uses the Arm Serial Wire Debug (SWD) interface with two dedicated pins (SWDIO and SWCLK on P1[0] and P1[1]). It supports full on-chip debugging, including breakpoints, watchpoints, memory inspection, and real-time variable monitoring without requiring JTAG headers or external emulators.
Does CY8C4244PVA-442Z support capacitive touch sensing without external components?
Yes - it integrates a dedicated CapSense® Sigma-Delta (CSD) hardware engine with >5:1 SNR and built-in water tolerance. All required analog resources (IDACs, opamps, modulators) are on-die, enabling robust self-capacitive or mutual-capacitive touch sensing directly on any GPIO pin without external RC networks or dedicated touch controller ICs.
Can the SAR ADC operate during Deep Sleep mode?
No - the 12-bit SAR ADC requires the main clock domain and cannot sample in Deep Sleep. However, the two low-power comparators remain active in Deep Sleep and can trigger wakeup events. For low-power periodic sensing, use Stop Mode with RTC-triggered wakeup followed by brief Active Mode ADC acquisition.
Is the flash memory field-upgradable via standard interfaces?
Yes - CY8C4244PVA-442Z supports in-system programming (ISP) via SWD using standard tools like MiniProg3 or third-party Arm debug probes. It also supports bootloader-based field updates over SCB-configured UART, I²C, or SPI - with configurable flash protection levels (Open/Protected/Kill) to prevent unauthorized access.
