Embedded Artists launches 1GHz NXP i.MX RT1176 Crossover MCU module and devkit

Microcontrollers used to be those cute little chips clocked at 8 MHz, but it’s now common to have MCUs clocked at one or two hundred Megahertz, and with Cortex-M7 cores, several hundred Megahertz is now possible, and NXP even pushed the limit to one Gigahertz with their i.MX RT1170 series of Cortex-M7/M4 Crossover MCUs announced over a year ago. Embedded Artists has now made a computer-on-module and a corresponding devkit based on NXP i.MX 1176 Crossover MCU clocked at one Gigahertz. iMX RT1176 uCOM MCU module delivers up to 6468 Coremarks, comes with up to 32MB SDRAM, 16MB QSPI flash, optional WiFi and Bluetooth, and various peripherals in a tiny 45x42mm form factor. iMX RT1176 uCOM module Specifications: SoC – NXP i.MX RT1176 processor with Cortex-M7 core up to 1 GHz/800MHz (Commercial vs industrial), Cortex-M4 core up to 400/200 MHz, 2MB internal SRAM, 2D GPU with OpenVG 1.1 support and 2D accelerator (PXP); note: no VPU for video decoding/encoding System […]

DevEBox STM32H7 Development Boards are made for Factory Automation

When it comes to STMicroelectronics’ STM32H7 series, there are three product lines- Dual-core lines, Single-core lines, and Value lines. ARM Cortex-M7 based – STM32H7 MCU series is capable of delivering 1327 DMIPS/ 3224 CoreMark. These MCUs are designed for factory automation (HMI, process control, power management), connectivity & security (Alarm panel, Wireless Modules). To continue with the growth of the STM32H7 series, we have China-based MCUdev DevEBox’s STM32H7XX-M development boards taking a single-core line and a value line module. The two STM32H7XX-M development boards use STM32H743VIT6 and STM32H750VBT6 core modules. The STM32H743VIT6 comes from a single core line that offers ARM Cortex-M7 gets up to 2 Mbytes of dual-bank flash memory and 1 Mbytes of RAM. While the STM32H750VBT6 module from the value line is one of the cost-effective STM32H7 devices featuring 128 Kbytes of flash memory. STM32H7 Development Boards These boards from MCUdev measure approximately 40mm x 68mm in size with the same peripherals. The manufacturer has produced both […]

New STM32H7 Cortex-M7 MCUs Clock at 550 MHz, Feature Octal SPI Flash and Ethernet Interfaces

STM32H7 Family Matrix with 550MHz Cortex-M7 MCU

STMicro launched STM32H7 single-core Cortex-M7 microcontroller family a while ago, followed by some dual-core Cortex-M7/M4 models, with most clocked up to 480 MHz. The company has now announced five faster parts clocked at up to 550 MHz with STM32H723, STM32H733, STM32H725, STM32H735, and STM32H730 which STMicro claims is “the fastest core speed in the market among MCUs that integrate Flash storage on-chip to run deeply embedded applications”. The embedded flash storage is important, as you may now NXP i.MX RT1170 Cortex-M7/M4 crossover processor can reach up to 1 GHz but does not include flash storage. Key differences in STM32H7 550 Mhz MCUs We’ve highlighted the five new microcontrollers in the table above, and beside the higher 550 MHz frequency delivering 2778 CoreMark and 1177 DMIPS, we can see those are the only parts that support both OctoSPI flash and Ethernet, and all five parts are designed for HMI applications with a TFT-LCD interface. The blog post following the announcement also […]

Teensy 4.1 Board Gets Longer for Ethernet, MicroSD Slot, and More GPIOs

What comes after Teensy 4.0? Teensy 4.1. The new version of the Arduino compatible board is powered by the same NXP i.MX RT1062 Cortex-M7 crossover processor clocked at 600 MHz, but about doubling in length in order to add a 10/100 Mbit Ethernet PHY, a MicroSD card slot, and offer more I/Os.

NXP i.MX RT1170 Arm Cortex-M7/M4 Microcontroller Clocks at One Gigahertz!

Microcontrollers used to be those cute little things that clock at 8 or 16 MHz, but in the last decade, Cortex-M3/M4 microcontrollers became more powerful with 100 to 200 MHz clocks being quite common. But with the introduction of Arm Cortex-M7 core about 5 years ago, microcontrollers are seriously starting to take over tasks that were previously reserved to faster microprocessors. As I remember it, the MCU frequency “race” started with STMicro STM32H7 in 2016 with an impressive 400 MHz, and NXP i.MX RT crossover processor clocked at 600 MHz a few years later. But with i.MX RT1170 microcontroller, NXP has upped the ante as the new MCU combines an Arm Cortex-M4 core clocked at 400MHz with Arm Cortex-M7 core running at an amazing one Gigahertz (1 GHz). The documentation has not been released and we have limited information, but here’s what we know about NXP i.MX RT1170 key features and specifications so far: CPU Arm Cortex-M7 @ 1 GHz […]
