Microchip Introduces Its First Trust&GO Wi-Fi 32-bit MCU Module

With the technology more and more taking control of our world, such as factories and homes, long gone are the days where you just wanted to dim the lights a little bit Now, we want our house heated just before we come in, the garage doors to open themselves, among other things. The stakes are getting higher every day, and so is the power these home automation devices have on your house. Of course, nobody wants their highly technological house being tapped into by some cyber intruders. What do we do in this case? We go for a more secure IoT environment!

This is exactly the premise of the WFI32E01PC, the first ever Wi-Fi microcontroller with Microchip’s Trust&GO hardware security element, pre-provisioned for popular cloud platforms, but it does not end there. When it comes to the Wi-Fi connectivity, the WFI32E01PC supports 2.4 GHz 802.11 b/g/n and has the best-in-class WLAN functionalities, covering the latest security standard for it, providing also Wi-Fi Protected Access 3 (WPA3), along with the other general Wi-Fi functions, such as AP, STA, SoftAP, TLS, WPA / WAP2, among others.

But besides providing a more secure Wi-Fi environment for your IoT projects, what else can it do? Well, as stated before, it is a highly integrated package, powered by the PIC32MZW1 series Wi-Fi SoC, which, besides the Wi-Fi, contains a high performance MCU, with a very rich set of peripheral options, including ethernet, USB, ADC, CVD touch buttons, CAN, among many other things, making it a very complete option for most IoT projects, helping you to build complex applications with WLAN, TCP / IP stack, RTOS, cloud connectivity and other functionalities.

The specs we are looking at are:

  • For the MCU:
    • MIPS32 M-Class microprocessor core, clocked at 200 MHz
    • Memories: 1 MB embedded Flash, 256 kB SRAM (for program and data) and 64 kB data buffer
    • Rich high performance peripheral options, including full-speed USB, CAN, CAN-FD, 10/100 MAC, and high accuracy 12-bit dual ADCs
    • 3xUART, I2C, 2xSPI peripherals
    • Operating voltage ranging from 3.0 to 3.6 V
    • Operating temperature range from -40 to 85 ºC
  • For the Wi-Fi module:
    • Single-band 2.4GHz b/g/n
    • Support for WPA / WPA2 / WPA3 Personal, TLS and SSL Wi-Fi security protocols
    • Support for AP, STA, SoftAP, Wi-Fi Direct functionality
    • Optional hardware crypto accelerator
    • PCB antenna

From the spec list of both the MCU and the Wi-Fi transceiver, you can imagine all the nice IoT projects you can apply it with, ranging from the (largely discussed) home and industrial automation, security systems and other projects where securit may be important, now you have another solid candidate. Regarding pricing, you are looking at around $12 for the neat package, which value can decrease in higher quantities, of course.
