ARM Cortex-M4 core-based MCU Touts Signal-processing Capabilities and Faster Operations
Wed, 09/21/2011 - 11:05am
STMicroelectronics announced the introduction of its new STM32 F4 Series of microcontrollers (MCUs). This extension to the STM32 platform is based on the latest ARM Cortex-M4 core, which adds signal-processing capabilities and faster operations to the portfolio of STM32 MCUs. The single-cycle DSP instructions of the STM32 F4 open the doors to the digital signal controller (DSC) market that requires high computational capability and DSP instructions for demanding applications such as high-end motor control, medical equipment and security. By providing a simple, full pin-to-pin and software compatible upgrade from the STM32 F2 Series, the F4 Series operates at a higher frequency (168 MHz instead of 120 MHz), offers single-cycle DSP instruction support and a Floating Point Unit, larger SRAM (192 Kbytes vs. 128 Kbytes), embedded flash memory from 512 Kbytes up to 1 Mbyte, and advanced peripherals for imaging, connectivity and encryption. Additional features include ultra-fast data transfers, with a 7-layer multi-AHB bus matrix and multi-DMA controllers, which allow concurrent execution and data transfers.
