Introduction

The PIC32CX-BZ3 family of SoCs are general purpose, low-cost, 32-bit Microcontrollers (MCUs) with Cortex® M4F ARM® processor, secure Bluetooth® Low Energy 5.2, IEEE® 802.15.4 wireless connectivity, an ultra-low power 2.4 GHz transceiver, a hardware-based security accelerator, capacitive touch capabilities and secure boot functionality.

The WBZ35x modules, which are fully RF-certified wireless modules, are built around PIC32CX-BZ3 SoC. The WBZ35x modules are available with a PCB antenna or U.FL connector for an external antenna.

The PIC32CX-BZ3 family supports a comprehensive range of peripherals for low-cost Internet of Things (IoT) solutions in automotive, smart factory and smart home applications.

• Analog-to-Digital Converter (ADC)
• Capacitive Voltage Divider (CVD) Controller for Touch Sensing
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I²C)
• Quad I/O Serial Peripheral Interface (QSPI)
• Universal Asynchronous Receiver-Transmitter (UART)
• Timer/Counter for Control Applications (TCC)
• Digital-to-Analog Converter (DAC)
• Local Interconnect Network (LIN)
• Serial Wire Debug (SWD)

The secure boot ROM has the capability to check the integrity and authenticity of the application prior to executing it. This verification mechanism is a key element to ensure the system root of trust for the deployment and execution of the secure firmware.
