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 […]

Amazon Fire TV Stick 4K Max (2023) features a 2 GHz MediaTek MT8696T CPU, support WiFi 6E

Amazon has recently introduced its second-generation Fire TV Stick 4K and Fire TV Stick 4K Max 2023 powered by MediaTek MT8696D and MT8696T Arm Cortex-A55 processors respectively and going for $49.99 and $59.99 on Amazon. The new Fire TV Stick 4K Max model is an incremental update compared to the Fire TV Stick 4K Max (2021) with basically the same processor but clocked slightly higher, twice the storage capacity, and WiFi 6E support instead of just WiFi 6. The Fire TV Stick 4K (2023) is a more notable update compared to the very first Fire TV Stick 4K launched in 2018. Amazon Fire TV Stick 4K / 4K Max (codenames: AFTKM and AFTKRT) specifications: SoC Fire TV Stick 4K (2023) – MediaTek MT8696D with quad-core Arm Cortex-A55 processor @ 1.7 GHz, Imagination GE9215 GPU @ 650MHz Fire TV Stick 4K Max (2023) – MediaTek MT8696T with quad-core Arm Cortex-A55 processor […]

Cortex-M55 based Arm Virtual Hardware is now available in AWS Cloud

The Arm DevSummit 2021 is taking place on October 19-21, and the first announcements from Arm are related to IoT with “Arm Total Solutions for IoT delivering a full-stack solution to significantly accelerate IoT product development and improve product ROI”, “Project Centauri” aiming to achieve for an extensive Arm Cortex-M software ecosystem in the way that Project Cassini does for the Cortex-A ecosystem, starting with support for PSA Certified and Open-CMSIS-CDI cloud-to-device specification, and Arm Virtual Hardware based on Corstone-300 IoT platform with a Cortex-M55 MCU core and an Ethos-U55 microNPU accessible from Amazon Web Services. The first two are quite abstract right now, and more information may become available in the future, but the Arm Virtual Hardware is available now from AWS as a public beta, with 100 hours of free AWS EC2 CPU credits for the first 1,000 qualified users. The virtual hardware does not emulate only the […]
