LONDON – STMicroelectronics NV (Geneva, Switzerland) has announced it has started delivering samples of its STM32 F3 series of microcontrollers which include a variety of analog peripherals and DSP capability.
STM32 F3 series MCUs are system-on-chip devices based on the Cortex-M4 core with FPU licensed from ARM Holdings plc, and are optimized for efficient handling and processing of mixed signals in circuits such as three-phase motor controls, biometrics and industrial sensor outputs or audio filters.
The F3 series includes 70 different chip designs and sits between the STM32 F1 range, based on the Cortex-M3 core, and the high performance STM32 F4 range, based on the Cortex-M4 plus FPU cores together with large embedded memory and clock frequencies up to 168-MHz.
With the addition of F3 microcontrollers, ST's STM32 family now offers more than 350 variants, ST said. The F3 series combines analog peripherals and DSP capability.
Peripherals include a 12-bit analog-to-digital converter (ADC) with 5-Msamples per second performance or up to three 16-bit sigma-delta ADCs on chip.
Prices for the STM32F3 devices start from about $2.24 for 1,000 unit quantities with lower prices for higher quantities. Devices are sampling now and are scheduled to enter full production in 3Q12.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
