Microchip PIC32MZ-W1 is a 32-bit MIPS WiFi MCU with 60+ GPIO, USB, CAN Bus, Ethernet, and more

PIC32MZ W1 and WFI32 2.0 Curiosity Board

Microchip recently released the PIC32MZ-W1 wireless MCU along with 20 other WiFi parts, including WiFi MCUs, link controllers, network controllers, and plug-and-play modules. Among them, the PIC32MZ-W1 wireless MCU is the most interesting because of its 32-bit MIPS microAptiv M-class core running at up to 200MHz, advanced hardware security features, and integrated Microchip Trust Platform for secure cloud authentication. Over the years ESP32 MCUs have become the go-to choice for wireless applications. Still, one problem we always have with ESP32 SoCs is their limited GPIO option due to their strapped-out pin structures. But this new MCU has over 60 GPIO pins to work with along with Ethernet MAC, USB, CAN Bus, CANFD, SPI, I2C, SQI, UART, ADC, JTAG, and more. PIC32MZ-W1 wireless MCU specifications MCU MIPS32 M-Class core clocked at 200 MHz 16KB I-Cache, 16KB D-Cache microMIPS mode (up to 35% smaller code size) DSP extensions (4x 64-bit accumulators, single-cycle […]

ESP USB Bridge project converts ESP32-S2 or ESP32-S3 into a USB to UART/JTAG chip

Espressif’s ESP USB Bridge is a project based on the ESP-IDF that leverages ESP32-S2 or ESP32-S3 USB interface to use the board as a USB to UART or USB to JTAG debug board. It can serve as a substitute for USB to TTL debug boards based on CH340 or CP2104 for instance, be used with OpenOCD in JTAG bridge mode, and also flash UF2 firmware file to the target board. As just mentioned, there are three main use cases: Serial bridge mode with a terminal program or a firmware flashing tool like esptool. In that case, it just works like your typical USB to TTL debug board JTAG bridge mode for JTAG debugging with OpenOCD, and if the target board is based on ESP32, you can use openocd-esp32 project Mass storage device where the board can be accessed by a file manager on the host computer. One of the specific […]
