Overview

The CY8C6347BZI-BLD33 is a high-performance, dual-core PSoC 6 microcontroller featuring an Arm Cortex-M4F for primary application processing and an Arm Cortex-M0+ for low-power tasks and security. It integrates a Bluetooth Low Energy (BLE) 5.0 subsystem and extensive programmable analog and digital peripherals in a compact 116-BGA package. This device is optimized for power-constrained IoT applications that require hardware-based security and flexible connectivity.

Why Choose This Part

The PSoC 6 architecture provides a unique balance of performance and efficiency, offering up to 150MHz processing while maintaining ultra-low power consumption in deep sleep modes. Its hardware-based Root of Trust and eFuse-based security features ensure secure boot and data protection for sensitive IoT deployments. The integrated BLE 5.0 radio and SIMO DC-DC buck converter significantly reduce the total BOM and board space requirements.

Applications

Getting Started

Development is primarily supported through Infineon ModusToolbox Software, which provides the necessary libraries, drivers, and middleware for dual-core and BLE configuration. Engineers can prototype quickly using the PSoC 6 BLE Pioneer Kit (CY8CKIT-062-BLE) and leverage the CapSense tuner for touch interface optimization. Hardware debugging is facilitated via Serial Wire Debug (SWD) using standard probes like J-Link or the onboard KitProg3.
