Product details
Overview
CY8C614AFNI-S2F43T from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSOC™ 61 MCU with 2048 KB flash, 1024 KB SRAM, and integrated CAPSENSE™, QSPI/XIP, USB FS, and hardware cryptography. It operates at 150 MHz (M4) and 100 MHz (M0+), supports 1.7–3.6 V supply, and delivers 40 µA/MHz active current at 1.1 V core voltage. Designed for secure, ultra-low-power IoT edge nodes requiring real-time sensor fusion and touch interface.
For engineers reviewing the CY8C614AFNI-S2F43T datasheet, CY8C614AFNI-S2F43T pinout, CY8C614AFNI-S2F43T application, or CY8C614AFNI-S2F43T equivalent, key selection criteria include dual-CPU power efficiency trade-offs, SMIF XIP throughput up to 640 Mbps, Deep Sleep current of 7 µA with 64 KB SRAM retention, and hardware-accelerated AES/SHA/TRNG support.
Technical Context
The device implements a tightly coupled dual-CPU subsystem where the Cortex-M4F handles application processing and the Cortex-M0+ is reserved exclusively for system-level functions including security boot, power management, and peripheral arbitration-no application code runs on M0+. Both cores share memory-mapped peripherals via a high-bandwidth interconnect with three independent DMA controllers.
Its clock architecture integrates two PLLs, an FLL, dual crystal oscillators (16–35 MHz + 32 kHz), and programmable integer/fractional dividers to deliver precise, low-jitter clocks to TCPWMs, SCBs, and USB. The on-chip DC-DC buck converter enables sub-1 µA quiescent operation in Deep Sleep while maintaining backup domain RTC and 64-byte memory retention.

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 |
|---|---|---|---|
| CY8C6247FMI-BLD13 | Same CY8C6x family, but 124-ball BGA package; includes additional 2× CAN FD controllers and higher-temp grade (–40°C to +105°C) | Targeted at automotive body electronics and industrial PLCs requiring CAN bus integration and extended thermal range | Select when CAN FD interface and industrial temperature rating are mandatory; BGA footprint increases board assembly cost vs. WLCSP |
| STM32WB55RGV | Single-core Cortex-M4 + dedicated Cortex-M0+ radio coprocessor; Bluetooth LE 5.0 integrated; 1 MB flash, 256 KB RAM; no SMIF/XIP or CAPSENSE™ | Optimized for Bluetooth-centric wireless sensor nodes; lacks analog-rich peripherals and segment LCD driver | Choose for BLE-first designs where RF integration outweighs need for high-resolution ADC, touch, or external flash execution |
Compared with CY8C614AFNI-S2F43T, CY8C6247FMI-BLD13 adds CAN FD and wider temperature tolerance at the cost of larger package and higher BOM complexity, while STM32WB55RGV trades analog/sensing depth and external flash flexibility for integrated BLE radio and lower RF certification effort.

FAQ
Is CY8C614AFNI-S2F43T pin-compatible with other CY8C61xA devices?
Yes-CY8C614AFNI-S2F43T uses the 100-ball WLCSP package defined in the CY8C61xA family datasheet (002-30714 Rev. *F). Ball assignments for VDDIO, VDDA, XRES, SWD, USB, and GPIO banks match across all 100-ball variants, enabling direct PCB reuse for different flash/RAM configurations within the same die revision.
Does the Cortex-M0+ core support user firmware execution?
No-the Cortex-M0+ in CY8C614AFNI-S2F43T is reserved exclusively for system functions including secure boot, power mode transitions, interrupt routing, and peripheral arbitration. Infineon's PSOC™ 61 architecture explicitly prohibits application code execution on the M0+; all user firmware must run on the Cortex-M4F core.
What is the maximum supported QSPI clock frequency in SMIF XIP mode?
The SMIF interface supports up to 160 MHz input clock, enabling theoretical peak throughput of 640 Mbps in octal DDR mode. In practice, XIP performance depends on external flash timing parameters and PCB signal integrity; the on-chip 4 KB cache mitigates latency for sequential instruction fetches, sustaining >90% of peak bandwidth under typical firmware access patterns.
How is CAPSENSE™ tuning handled in production firmware?
CAPSENSE™ tuning is fully automated via SmartSense™-a hardware-accelerated algorithm that dynamically adjusts IDAC current, scan resolution, and baseline tracking without host CPU involvement. Firmware invokes Cy_CapSense_RunTuner() once during initialization; subsequent recalibration occurs autonomously in response to environmental drift or liquid presence, eliminating manual calibration steps in manufacturing test.
