WinnerMicro W806 240 MHz MCU finds it way into a $2 development board

I’ve just been notified about an inexpensive board (HLK-W806) based on WinnerMicro W806 32-bit XT804 (XuanTie E804) microcontroller clocked at up to 240 MHz and equipped with 1MB flash and 288KB RAM. XuanTie is the microcontroller family from Alibaba’s subsidiary T-Head Semiconductor, notably XuanTie RISC-V cores, but I’ve just learned not all XuanTie cores are based on the RISC-V architecture, and as we’ll see below, Xuantie E804 core appears to be based on the C-Sky architecture. It may still be interesting, as it’s in the STM32 board price range (pre-2020), but with a much higher frequency, so let’s have a look. HLK-W806 development board specifications: MCU – WinnerMicro W806 32-bit XT804 microcontroller @ 240 MHz with 1MB Flash, 288KB RAM, FPU, DSP, crtypto engine Expansion – 2x 24-pin headers with (based on MCU specs) 1x SDIO host with support for SDIO 2.0, SDHC, MMC 4.2 1x SDIO device up to […]

Raspberry Pi smart audio devkit features AISonic IA8201 DSP, microphone array

Knowles AISonic IA8201 Raspberry Pi development kit is designed to bring voice, audio edge processing, and machine learning (ML) listening capabilities to various systems, and can be used to evaluate the company’s AISonic IA8201 DSP that was introduced about two years ago. The kit is comprised of three boards with an adapter board with three buttons connecting to the Raspberry Pi, as well as the AISonic IA8210 DSP board itself connected via a flat cable to a microphone array. Knowles AISonic Raspberry Pi development kit Knowles did not provide the full details for the development but says it enables wake-on-voice processing for low latency voice UI, noise reduction, context awareness, and accelerated machine learning inferencing for edge processing of sensor inputs. Some of the use cases include Low Power Voice Wake to listen for specific OEM keywords to wake the host processor, Proximity Detection when combined with an ultrasonic capable […]

TI AM64x 7-core processor is made for PLC’s, motor drives, industrial robots

Texas Instruments AM64x is a family of 64-bit Arm processors with functional safety designed for Programmable Logic Controllers (PLC), motor drives, remote I/O, and industrial robots. The top-end processor of the family, AM6442, comes with seven cores including two Cortex-A53 application cores, four Cortex-R5F real-time cores, and one Cortex-M4F isolated core. AFAICT, while the documentation is dated January 2021 and TI announced the processor in February in a blog post with a cryptic title, it was only first picked up by Embedded Computing in early May. Besides the processor itself, TI also provides an AM64x starter kit and a full-featured AM64x evaluation kit, and several companies are already preparing development boards and modules as we’ll see further below. TI AM64x processor AM64x key features & specifications: CPU cores Dual-core Arm Cortex-A53 processor @ 1.0 GHz with 256KB L2 shared cache with SECDED ECC, 32KB L1 D-cache, 32KB L1 I-cache Up […]
