STMicroelectronics launches their new STM32 F4 microcontrollers series. The STM32 F4 is based on the latest ARM Cortex-M4 core. There are four variants in the STM32 F4 Series: STM32F405x (USB On-The-Go), STM32F407 (two USB OTG), STM32F415 (STM32F405 with a crypto/hash processor) and STM32F417 (STM32F407 with a crypto/hash processor). All four versions are in volume production. Prices start at $5.74 for the STM32F407VET6 with 512 Kbytes of Flash and 192 Kbytes RAM in the LQFP100 package.
ARM introduced the Cortex-M4 processor for digital signal control (DSC) applications. The Cortex-M4 processor features a single-cycle multiply-accumulate (MAC) unit, optimized single instruction multiple data (SIMD) instructions, saturating arithmetic instructions, and an optional single precision Floating-Point Unit (FPU). The Cortex-M4 processor has been licensed by five leading MCU semiconductor companies including NXP, STMicroelectronics and Texas Instruments.
