Microchip Technology is introducing its first PIC microcontroller family with Bluetooth Low Energy wireless and the ARM Cortex-M4F core with digital signal processing support.

Microchip’s PIC32CX-BZ2 family includes System-on-Chip (SoC) devices as well as global regulatory-certified, RF-ready modules. In addition to Bluetooth Low Energy, the chip supports Zigbee stacks and Over the Air (OTA) update capabilities.

The hardware includes a 12-bit analog to digital converter (ADC), multiple timer/counters for control (TCC) channels, an on-board encryption engine, and a broad set of interfaces to touch, CAN, sensor, display and other peripherals. The 1 MB of Flash memory supports large application codes, multiprotocol wireless stacks and OTA updates. AEC-Q100 Grade 1 (125 °C) qualified packages further simplify wireless connectivity integration where highly robust solutions are required.

“Our PIC32CX-BZ2 MCU family removes barriers that have made it difficult to bring wireless applications to market, from availability problems and complexity challenges to regulatory certification hurdles and long-term support concerns,” said Steve Caldwell, vice president of Microchip’s wireless solutions business unit.

“Our family tightly integrates wireless connectivity with an MCU that is built on our decades of specialized experience and backed by a vertical manufacturing approach that encompasses ICs, Microchip’s highly integrated software stacks, in-house module manufacturing and a customer-driven obsolescence practice.”

The PIC32CX-BZ2 chips are supported by Microchip’s MPLAB Harmony 32bit embedded software development framework. MPLAB Code Configurator integration enables developers to quickly begin prototyping with the PIC32CX-BZ2 family using drag-and-drop auto code generation.

Numerous application code examples are hosted on GitHub and linked through MPLAB Code Configurator and MPLAB Discover.

Developers with little to no RF expertise can use Microchip’s WBZ451 modules that are pre-certified to multiple regulations around the world with an optimized on-board RF design.

In addition to the MPLAB Code Configurator, the MPLAB Harmony v3 framework includes numerous other tools and an ecosystem of debuggers, programmers, virtual sniffer, and compilers. Other support includes GitHub demo applications and documentation, wireless design check services, and building blocks that walk developers through all the steps involved in the application development process.

The PIC32CX-BZ2 family is supported by the PIC32CX-BZ2 and WBZ451 Curiosity Development Board.

The PIC32CX-ZB2 family is in-stock and available now. PIC32CX1012BZ25048-I and PIC32CX1012BZ25048-E SoCs ship in 7 x 7 mm 48 Quad-Flat No-leads (QFN) packages.

The WBZ451PE-I and the WBZ451UE-I modules come with an on-board Printed Circuit Board (PCB) antenna and a U.FL connector for external antenna respectively.
