W6300-EVB-Pico2 board combines RP2350 MCU with WIZnet W6300 QSPI Ethernet controller for 80+ Mbps data rate

W6300-EVB-PICO2 board with Raspberry Pi RP23500 and W6300 QSPI Ethernet controller

WIZnet W6300-EVB-Pico2 is a development board that combines a Raspberry Pi RP2350 MCU with the company’s new W6300 QSPI Ethernet controller capable of 80+ Mbps data rates. WIZNet has made several 10/100Mbps Ethernet controllers over the years that connect to microcontrollers via SPI, but the speed is often limited to 15 to 70 Mbps due to a low SPI clock frequency and small buffers. The WIZNet W6300 Ethernet controller can deliver higher speed thanks to a 150MHz system clock, a QSPI interface with four data lines, 64KB SRAM, and 4KB TX/RX buffer for each of the 8 sockets. W6300 QSPI Ethernet controller W6300 features and specifications: Host Interface – High-speed QSPI (MODE 0/3), system bus with 2 address signals & 8-bit data Internal 32KB SRAM for Tx/ Rx buffers (64KB in total) 8x independent sockets with 64KB Memory 10BaseT / 10BaseTe / 100BaseTX Ethernet PHY Integrated Auto negotiation (Full and […]

STMicro STM32MP23 Cortex-A35/M33 MPU features a 600 GOPS NPU for industrial IoT and ML applications

STMicroelectronics STM32MP23 is a dual-core Cortex-A35 general-purpose microprocessor (MPU) with a Cortex-M33 real-time core, and 600 GOPS of performance operating at up to 125°C and designed for industrial and Internet-of-Things (IoT) edge computing, advanced HMI, and machine-learning (ML) applications. It follows the STM32MP25 series unveiled in 2023 and launched the following year as the first member of the STM32MP2 family. The STM32MP23 is a cost-down version of the STM32MP25 with similar specifications (and pin-to-pin compatible packages), but the new family has a weaker 0.6 TOPS NPU, and tops at two Ethernet ports for the high-end parts instead of three. Ditto for CAN Bus interfaces (2x vs 3x). Other changes include a 16-bit memory interface and the lack of PCIe and USB 3.0 interfaces. STM32MP23 specifications: CPU – Single or dual Arm Cortex-A35 cores running at up to 1.5 GHz or 1.2 GHz with 512KB L2 cache Real-time MCU – Arm […]

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

7.5inch NFC Powered e Paper V2 side view

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock.

Preparing IoT Security for the Quantum Computing Era

CNXSoft: This is a guest post by Avishay Shraga, Sr. Director (CTO), Head of Security Technologies at Sony Semiconductor Israel, discussing IoT security as quantum computing draws near. The key to modern asymmetric cryptography is to create an equation that is easy to solve in one direction but difficult to reverse by an adversary in the other direction. Traditionally, this was done through modular arithmetic, where a large prime modulus and a generator were used to generate a key, although there are multiple methods to do so. The strength of this one-way function is measured by the time and computing power needed to reverse it. ECC 256, considered by many to be one of the gold standards in modern cryptography, would take millions of years to crack using current computing and capabilities. Today’s encryption standards are more than adequate in securing real-time and historical data in IoT devices. However, as […]
