Overview

The CY8C6347FMI-BLD43T is a dual-core PSoC 6 microcontroller featuring a 150MHz Arm Cortex-M4 and a 100MHz Arm Cortex-M0+ dedicated to low-power tasks and security. It integrates an on-chip Bluetooth Low Energy (BLE) 5.0 subsystem and 1MB of Flash, packaged in a compact 104-WLCSP for space-constrained designs. The architecture is designed for ultra-low-power IoT applications, utilizing a built-in SIMO buck converter for high efficiency.

Why Choose This Part

The PSoC 6 architecture provides an industry-leading power profile with deep sleep current as low as 7uA and active power consumption around 22uA/MHz. Its dual-core design allows for physical isolation of sensitive security tasks from application code, while the integrated CapSense peripheral offers robust capacitive sensing for modern user interfaces.

Applications

Wearable Health Monitors
Utilizes the dual-core architecture to offload BLE stack and sensor hub tasks to the M0+ while the M4 handles data processing.
Smart Home Sensors
Leverages CapSense for touch-sensitive interfaces and integrated BLE for wireless mesh connectivity.
Secure IoT Gateways
Employs the hardware security features and dual-core isolation to manage encrypted communication and secure boot processes.

Getting Started

Engineers should use the ModusToolbox software environment for configuration and development. For hardware evaluation, the CY8CKIT-062-BLE Pioneer Kit is the primary platform, supporting easy access to the dual-core features and BLE antenna. Debugging is typically performed via SWD/JTAG using the integrated KitProg3 or an external J-Link probe.

Also Consider

STM32WB55CGU6 STMicroelectronics - A dual-core (M4/M0+) wireless MCU with multi-protocol support including BLE, Zigbee, and Thread.
EFR32BG22 SiLSilicon Labs - Provides even lower active current consumption for simple BLE-only sensor nodes where dual-core flexibility is not required.
