Description

Part of the **PIC32CX-BZ family**, WBZ351PE is a secure, low-cost 32-bit microcontroller module with an inbuilt wireless subsystem certified for Bluetooth® and Zigbee®. Designed from the ground up to enable you to go to market quickly, WBZ351PE is powered by a 64 MHz ARM® Cortex® M4F and is packed with features. --- **RF-ready with onboard antenna:**RF design is complicated but the WBZ351 makes it easier. With our RF-ready, PCB antenna, you don’t need to be an RF-expert to add wireless to your application, saving you time and RF-design costs. **Global regulatory-certified**: Radio certification is also complicated and can take a long time to complete. Our WBZ351PE modules are pre-certified in US, Canada, Europe, China, Taiwan, Japan and Korea helping you go to market quicker. **Ultra-low power 2.4 GHz transceiver:** Build applications enabling Bluetooth Low-Energy (LE) 5.2, IEEE® 802.15.4 / Zigbee 3.0 connectivity with hardware-level arbitration for multi-protocol wireless functionality. **Hardware-based security (secure boot):** Protect applications with NIST-compliant authentication and secure boot ROM to ensure only trusted software runs on your system. **Robust Analog Peripherals:** Industrial-grade capacitive touch, ADCs, DAC and comparators enable versatile sensor integration and analog management for a wide range of applications. **Functional safety:** This device supports the [ISO 26262 (ASIL B)](https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors/32-bit-mcus/32-bit-functional-safety/iso-26262-automotive), and [IEC 61508 (SIL 2)](https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors/32-bit-mcus/32-bit-functional-safety/industrial-safety-self-test-library) functional safety standards. The Functional Safety Manual, FMEDA and Diagnostic Software information are available under NDA. [Contact us](https://microchip.my.site.com/schedulemeetingportal/s/) for more information. **Easy development**: Built on the MPLAB® Harmony® v3 framework, application development for WBZ351PE is simple. Start prototyping in seconds using drag-and-drop building blocks or one of our many demo applications. [Go to the application developer's guide](https://onlinedocs.microchip.com/oxy/GUID-99E91F8E-E9F7-4C2C-B98A-E9662A2ABA50). **New to wireless?**We have a step-by-step guide to walk you through the entire Bluetooth development process from scratch. --- **Related Products** Visit our [PIC32CX-BZ and WBZ](https://www.microchip.com/en-us/products/microcontrollers-and-microprocessors/32-bit-mcus/pic32-32-bit-mcus/pic32cx-bz) wireless MCU family web page to compare all product variants. * For situations where a PCB antenna doesn’t work, the [WBZ351UE](https://www.microchip.com/en-us/product/Wbz351ue) offers the same features and performance but **replaces the built-in antenna** **with a U.FL antenna connector.** * For applications requiring more memory, the [WBZ451PE](https://www.microchip.com/en-us/product/wbz451pe) offers **1 MB flash and 128 KB SRAM.** * **For greater control over your design**, consider the [PIC32CX5109BZ31048](https://www.microchip.com/en-us/product/pic32cx5109bz31048), the SoC core of the WBZ35 modules.
