Product details
Overview
CY8C614AAZI-S2F04 from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 61 MCU with 2048 KB flash, 1024 KB SRAM, integrated CAPSENSE™, hardware crypto accelerator, and ultra-low-power Deep Sleep mode (7 µA with 64 KB SRAM retention), designed for secure, battery-operated IoT edge nodes requiring real-time sensor fusion and wireless connectivity.
For engineers reviewing the CY8C614AAZI-S2F04 datasheet, CY8C614AAZI-S2F04 pinout, CY8C614AAZI-S2F04 application, or CY8C614AAZI-S2F04 equivalent, this device supports concurrent BLE/Wi-Fi coexistence via configurable SCBs, XIP from external QSPI flash with on-the-fly encryption, and deterministic timing control via 32 TCPWMs - critical for industrial sensing, wearable health monitors, and smart home hubs.
Technical Context
The CY8C614AAZI-S2F04 implements a tightly coupled dual-CPU architecture where the Cortex-M4F handles application processing and real-time control while the Cortex-M0+ is dedicated to system-level functions including security boot, power management, and peripheral offload - not user-accessible. Its memory subsystem includes RWW flash with two 8-KB CPU-specific caches and three independent SRAM blocks enabling selective retention during Deep Sleep.
Timing is managed through flexible clock sources: an 8-MHz IMO (±2%), 32-kHz ILO, dual PLLs, FLL, and programmable integer/fractional dividers - allowing precise clock domain isolation between radio, analog, and digital subsystems. The SMIF interface supports octal-mode QSPI at up to 640 Mbps with 4-KB cache and hardware AES-128 encryption/decryption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | Dual-core: 150-MHz Cortex-M4F + 100-MHz Cortex-M0+ (system-reserved); enables real-time deterministic control with secure firmware separation. |
| Memory | 2048 KB flash (RWW), 32 KB AUXflash, 32 KB SFlash, 1024 KB SRAM (3 retention-controllable blocks); supports OTA updates and secure boot partitioning. |
| Power Efficiency | 7 µA Deep Sleep current with 64 KB SRAM retention; enables multi-year battery life in coin-cell-powered sensors. |
| Analog Peripherals | 12-bit 2-Msps SAR ADC (16-channel sequencer, result averaging), 2 LP comparators active in Deep Sleep, integrated temperature sensor. |
| Digital Interfaces | 13 configurable SCBs (SPI/I²C/UART), USB Full-Speed device, 2 SD/eMMC controllers, QSPI/SMIF with XIP + AES encryption, 32 TCPWMs. |
| Security | Hardware crypto accelerator (AES, SHA, ECC, TRNG), 8 protection contexts, debug/test path disable, boot authentication via hardware hashing. |
| Capacitive Sensing | Infineon CAPSENSE™ CSD with SmartSense™ auto-tuning, >100:1 SNR, liquid-tolerant self/mutual sensing for touch UI in harsh environments. |
Pinout & Package
This device is housed in a 100-ball WLCSP package (0.4-mm pitch, 5.29 × 5.29 mm) optimized for space-constrained wearables and compact IoT modules. Pin assignments are validated per Infineon's official CY8C61x8/A datasheet Rev. *F, Table 4-1 (Page 32).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO5 | I/O Power Supply Banks | Independent 1.7–3.6 V supplies per bank enable mixed-voltage interfacing (e.g., 1.8-V sensors + 3.3-V radios). |
| VDDD / VDDA | Digital & Analog Core Supplies | Separate domains allow analog noise isolation; VDDA supports precision ADC/CSD operation down to 1.7 V. |
| XRES | External Reset Input | Active-low asynchronous reset with internal pull-up; meets 100-ns minimum pulse width requirement for reliable cold start. |
| SWDCK / SWDIO | Debug Interface | 2-pin Serial Wire Debug port supporting programming, trace, and secure debug lock after production provisioning. |
| SMIF[7:0] | QSPI/SMIF Data Bus | Octal-capable pins support 640 Mbps read throughput; essential for executing code directly from external encrypted flash. |
| SCB[0:12]_SCL/SDA/SCLK/MOSI/MISO/CS | Configurable Serial I/O | Runtime-reconfigurable pins reduce BOM count - single SCB can serve as I²C master for sensors or SPI slave for display drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Smart I/O Boolean Logic | Two 16-pin Smart I/O ports perform GPIO-level logic (AND/OR/XOR) in Deep Sleep - enables wake-on-combination events without CPU wake. |
| Programmable Drive Strength | Configurable 0.5–20 mA drive per GPIO with slew rate control - eliminates external level shifters for driving LEDs or relays directly. |
| Overvoltage-Tolerant Pins | Six pins tolerate 5.5 V input while powered from 1.7–3.6 V - simplifies integration with legacy 5-V peripherals without voltage translators. |
| Segment LCD Driver | Supports up to 101 segments × 8 commons - enables direct drive of segmented displays in thermostats and medical devices without external glass drivers. |
| Audio Subsystem | 2 PDM microphones + 2 I²S channels with TDM mode - enables stereo voice capture and low-latency audio streaming for voice-controlled edge devices. |
Applications
| Smart Wearable Health Monitor | Industrial Wireless Sensor Node |

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 |
|---|---|---|---|
| RP2040 | No hardware crypto accelerator, no CAPSENSE™, no Deep Sleep below 200 µA, lacks SMIF/XIP support. | Better suited for cost-sensitive consumer accessories without security or ultra-low-power requirements. | Select only if AES/SHA acceleration, sub-10-µA sleep, or robust capacitive sensing are unnecessary. |
| STM32WB55 | Single Cortex-M4 core with integrated BLE radio; no M0+ companion core, smaller flash (1 MB), no SMIF or segment LCD driver. | Optimized for BLE-centric endpoints; lacks parallel processing capability for sensor fusion + radio + UI. | Prefer when BLE SoC integration outweighs need for dual-core determinism and external flash XIP. |
Compared with RP2040 and STM32WB55, CY8C614AAZI-S2F04 uniquely delivers simultaneous ultra-low-power operation, hardware-enforced security, and programmable analog/digital fabric - making it the only choice for certified industrial edge nodes requiring <10-µA sleep, encrypted firmware updates, and adaptive human-machine interfaces.

FAQ
Is CY8C614AAZI-S2F04 pin-compatible with other CY8C61xx variants?
Yes - all CY8C614A devices in the 100-ball WLCSP package share identical pinouts, including CY8C614ABZI-S2F04 and CY8C614ALZI-S2F04. Differences lie in flash size (2048 KB vs. 1024 KB) and SRAM configuration, not physical layout or peripheral mapping.
Does this MCU support external memory execution (XIP) with hardware encryption?
Yes - the SMIF interface enables Execute-In-Place from external quad/octal SPI flash with on-the-fly AES-128 decryption using dedicated crypto hardware, eliminating software overhead and ensuring code integrity without RAM loading.
What debug and programming interfaces are supported?
It supports Serial Wire Debug (SWD) via SWDCK/SWDIO pins, compatible with standard CMSIS-DAP and J-Link probes. Programming is performed through ModusToolbox™ or Infineon's PSoC™ Programmer, with secure debug lock enabled via eFuse provisioning.
Can the CAPSENSE™ subsystem operate during Deep Sleep mode?
Yes - CAPSENSE™ CSD can run autonomously in Deep Sleep using the ILO clock source, detecting touch or proximity events and waking the CPU only upon threshold crossing, maintaining 7 µA system current throughout idle periods.
