The difference stm32f103zet6 and stm32f103vct6
1, STM32F series is the low-end ARM 32-bit microcontroller, the chips are STMicroelectronics (ST) produced by the company, its core is Cortex-M3.
Which STM32F series:
1) STM32F103 "Enhanced" series
2) STM32F101 "basic" series
3) STM32F105, STM32F107 "Internet-type" series
Enhanced series of clock frequencies up to 72MHz, is similar products in the highest performance products; basic clock frequency of 36MHz, the price of 16 products get more than 16 products significantly enhance the performance of the product is the best choice for 32 users. Both lines from 32K to 128K of the flash memory, except that the combination of the maximum capacity of the SRAM and peripheral interfaces. When the clock frequency is 72MHz, code execution from the flash memory, STM32 power 36mA, equivalent to 0.5mA / MHz.
