STMicroelectronics MCU a 32 bit STM32F302x6/x8 ARM-Cortex-M4
Le MCU a 32 bit ARM®-Cortex®-M4 STM32F302x6/x8 STMicroelectronics si basano su un nucleo RISC ARM Cortex-M4 a 32 bit che opera fino a 72 MHz di frequenza e integra una unità a virgola mobile (FPU). Questa famiglia di prodotti incorpora delle memorie ad alta velocità integrate (fino a 64 Kbyte di memoria Flash, 16 Kbyte di SRAM) e un'ampia gamma di I/O e periferiche collegati a due bus APB. Questi dispositivi offrono un veloce ADC a 12 bit (5 Msps), tre comparatori, un amplificatore operazionale, fino a 18 canali di rilevamento capacitivi, un canale DAC, un RTC a bassa potenza, un temporizzatore generico a 32 bit, un temporizzatore dedicato al controllo motore, fino a tre temporizzatori generici a 16 bit e un temporizzatore per azionare il DAC. Presentano inoltre interfacce di comunicazione standard e avanzate: tre I2C, fino a tre USART, fino a due SPI I2S full-duplex multiplexati, un dispositivo USB FS, un CAN e un trasmettitore a raggi infrarossi.
The STMicroelectronics STM32F302x6 and STM32F302x8 MCUs operate in the –40°C to +85°C and –40°C to +105°C temperature ranges from at a 2.0V to 3.6V power supply. A comprehensive set of power-saving mode allows the design of low-power applications. These devices are offeredin 32-pin, 48-pin, 49-pin, and 64-pin packages.
