PIC32WM-BZ6
The low-power module aims at multiprotocol applications. For example, IoT devices, heating, ventilation, air conditioning systems, automotive and telematics applications, and consumer electronics.
Supported connectivity standards include Bluetooth Low Energy (Bluetooth Core 6.0), Zigbee 3.0 and Thread 1.4. And there’s IEEE 802.15.4 MAC/PHY SDK for custom protocol support, perhaps for proprietary smart-home mesh networking protocols.
The PIC32WM-BZ6 module is built around the PIC32CX-BZ6 SoC. It includes analogue peripherals for motor control development and also touch and graphics support for advanced UIs.
The MCU features a 128MHz Arm Cortex-M4F processor with 2MB of Flash memory and 512KB of RAM. For security, it supports secure boot with an immutable root of trust, an AES, SHA, RSA and ECC cryptography accelerator, and a true random number generator. In terms of the cryptography, there’s encryption and decryption with key sizes of 128, 192 and 256 bits.
The pre-certified module includes a fully integrated RF front end, antenna and passive components.
