ST booth tour: STM32L4, STM32H7, startups, students at Embedded World 2017

Posted by Charbax – March 18, 2017

ST shows their best-in-class ultra-low-power STM32L4 microcontroller which delivers 100 DMIPS based on its ARM Cortex-M4 core with FPU and ST ART Accelerator at 80 MHz offering dynamic voltage scaling to balance power consumption with processing demand, low-power peripherals (LP UART, LP timers) available in Stop mode, safety and security features, smart and numerous peripherals, advanced and low-power analog peripherals such as op amps, comparators, LCD, 12-bit DACs and 16-bit ADCs (hardware oversampling). STM32L4 is available in these skews: STM32L4x1 (Access line), STM32L4x2 (USB Device), STM32L4x3 (USB Device, LCD), STM32L4x5 (USB OTG) and STM32L4x6 (USB OTG, LCD).

ST also shows their new STM32H7 platform, taking advantage of an L1 cache, STM32H7 can deliver the maximum theoretical performance of the ARM Cortex-M7 core, regardless if code is executed from embedded Flash or external memory: 2010 CoreMark /856 DMIPS at 400 MHz fCPU. STM32H7 supports AXI and multi-AHB bus matrixes for interconnecting core, peripherals and memories, 16 Kbytes +16 Kbytes of I-cache and D-cache, Up to 2 Mbytes of embedded dual-bank Flash memory, with ECC and Read-While-Write capability, high-speed master direct memory access (MDMA) controller, two dual-port DMAs with FIFO and request router capabilities for optimal peripheral management, and one additional DMA, Chrom-ART acceleration for efficient 2D image copy and double-precision FPU are also part of the acceleration features available in the device, peripheral speed independent from CPU speed (dual-clock support) allowing system clock changes without any impact on peripheral operations, even more peripherals, such as four serial audio interfaces (SAI) with SPDIF output support, three full-duplex I²S interfaces, a SPDIF input interface supporting four inputs, two USB OTG with dedicated power supply and Dual-mode Quad-SPI interface, two FD-CAN controllers, a high-resolution timer, a TFT-LCD controller, a JPEG codec, two SDIO interfaces and many other analog peripherals including three fast 14-bit ADCs, two comparators and two operational amplifiers. STM32H7 has 1 Mbyte of SRAM with a scattered architecture: 192 Kbytes of TCM RAM (including 64 Kbytes of ITCM RAM and 128 Kbytes of DTCM RAM for time-critical routines and data), 512 Kbytes, 288 Kbytes and 64 Kbytes of user SRAM, and 4 Kbytes of SRAM in backup domain to keep data in the lowest power modes, Security Authenticate and protect software IP while performing initial programming in production or firmware upgrades in the field.

This ST booth tour video at Embedded World 2017 in Nuremberg also features several demos from the STM32 Fan Zone area at Embedded World 2017 featuring demos including a Gameboy emulator and a color LED light display system from students from the Thomas More college, Seavus smart Shopping cart, Bixi gesture controls in the car, Xped IoT systems and ST is giving away more than 5000 development boards at the Embedded World.
