Microchip Technology PIC32CX-BZ2 & WBZ45 Family

Microchip Technology PIC32CX-BZ2 and WBZ45 Family are a series of microcontrollers and modules for wireless applications. The  PIC32CX-BZ2 are general-purpose, low-cost, 32-bit Microcontrollers. The MCUs support multi-protocol wireless interfaces (BLUETOOTH® and Zigbee®). The devices have a hardware-based security accelerator, transceiver, and Power Management Unit (PMU). The WBZ45 Module is a series of fully RF-certified wireless modules that contain the PIC32CX-BZ2 wireless MCUs with either a PCB antenna or u.FL connector for external antenna.
