STMicroelectronics has introduced a new line of microcontrollers that will leverage ARM Holdings plc’s latest Cortext-M7 core the Switzerland-based company says will double the processing and digital signal processing (DSP) power of the previous generation of device.
The newly-announced core has a six-stage superscalar ALU with branch prediction and supports single cycle dual 16-bit multiply accumulate (MAC) operations as well as 8- and 16-bit SIMD operations. The floating-point unit supports single and double precision IEEE754-compliant maths. It can achieve 400MHz clock frequency in a 40nm manufacturing process. The AXI interconnect supports 64-bit transfers and there are fully integrated optional caches for instruction and data of up to 64 kbytes each in size.
The MCU series, the STM32 F7, will be manufactured on ST’s 90nm embedded non-volatile memory CMOS process technology and is currently in the sampling stage. ST said it will demonstrate the MCU during ARM’s TechCon in Santa Clara, Oct.1-3. ARM said the embedded core is a good fit for applications including next-generation vehicles, connected devices, smart homes and smart factories.
Daniel Colonna, ST’s MCU marketing director, said in a statement the STM32 F7 is a “natural extension” to ST’s product portfolio and the memory performance of the devices “gives developers new possibilities for innovation, as they no longer need to optimize their code for performance and memory.”
