LONDON Ė 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.
