Product details
Overview
CY8C6244AZQ-S4D92 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 62 microcontroller with 256-KB flash, 128-KB SRAM, integrated CAN FD, USB Full-Speed, and hardware cryptography acceleration-designed for secure, ultra-low-power IoT edge nodes requiring real-time sensor fusion and wireless coexistence.
For engineers reviewing the CY8C6244AZQ-S4D92 datasheet, CY8C6244AZQ-S4D92 pinout, CY8C6244AZQ-S4D92 application, or CY8C6244AZQ-S4D92 equivalent, this MCU supports concurrent BLE/Wi-Fi coexistence via programmable digital logic, offers 7-µA Deep Sleep with 64-KB SRAM retention, and integrates CSD capacitive sensing with SmartSense auto-tuning for robust touch interfaces in battery-constrained devices.
Technical Context
The device implements a tightly coupled dual-CPU subsystem: the 150-MHz Cortex-M4F handles compute-intensive tasks (e.g., sensor fusion, crypto), while the 100-MHz Cortex-M0+ manages real-time peripherals and low-power state transitions. Inter-processor communication (IPC) and shared memory enable deterministic task partitioning without bus contention.
Its programmable analog subsystem includes two synchronized 12-bit 2-Msps SAR ADCs with 16-channel sequencer and Deep Sleep operation, a 12-bit DAC with <2-µs settling time, and two opamps with continuous low-frequency operation-enabling simultaneous analog signal acquisition and conditioning during system sleep.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core secure MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32WB55RG | Single-core Cortex-M4 + Cortex-M0+ radio co-processor; lacks integrated CAN FD and hardware crypto accelerators for asymmetric algorithms | Optimized for Bluetooth LE + IEEE 802.15.4 only; no native CAN or USB device stack support | Prefer when BLE/Wi-Fi coexistence is primary requirement and CAN FD is handled externally |
| RA6M5G | Single Cortex-M33 core with TrustZone; no second CPU, no CSD subsystem, no Smart I/O logic; higher active power (120 µA/MHz) | Targets functional safety (IEC 61508 SIL3) but lacks capacitive sensing and ultra-low-power Deep Sleep features | Prefer when ASIL-B compliance and large code footprint (>1 MB flash) dominate over capacitive UI and sub-10-µA sleep |
Compared with STM32WB55RG and RA6M5G, CY8C6244AZQ-S4D92 uniquely combines dual-core deterministic partitioning, on-die CAN FD, CSD with SmartSense, and <1-µA DC-DC quiescent current-making it optimal for battery-powered IoT hubs requiring mixed-signal autonomy and wired/wireless protocol convergence.

FAQ
What debug interfaces does CY8C6244AZQ-S4D92 support?
The device supports SWD (Serial Wire Debug) and JTAG via the SWJ-DP interface. Its 32-bit JTAG ID encodes die revision, part number hex ("E4B0"), and manufacturer ID ("069"). Debug access can be permanently disabled via eFuse programming to enforce secure boot enforcement and prevent unauthorized firmware extraction.
Does CY8C6244AZQ-S4D92 support external memory execution?
Yes-it features Quad-SPI/SMIF with Execute-In-Place (XIP) capability from external flash, including on-the-fly AES-256 decryption and a 4-KB cache to maintain performance while minimizing active power. XIP operates concurrently with CPU execution and supports single/dual/quad I/O modes up to 320 Mbps.
How is capacitive sensing implemented on this MCU?
It uses the Capacitive Sigma-Delta (CSD) block with hardware-accelerated SmartSense auto-tuning, supporting both self-capacitance (up to 61 electrodes) and mutual-capacitance (matrix scanning) topologies. The subsystem operates independently in Deep Sleep mode and delivers >80 dB SNR with built-in liquid tolerance and proximity detection.
What power modes are available and how do they differ?
Six modes: Active (full CPU/peripheral operation), Sleep (CPU clock gated, peripherals active), Deep Sleep (CPU and most clocks off, 7 µA with 64-KB SRAM retention), Hibernate (backup domain only, 1.2 µA), and two intermediate modes (System Deep Sleep and Flash Deep Sleep). Each mode has distinct retention scopes and wake sources defined in hardware.
