Misc STM discovery F4 design notes
Posted: Tue Jan 14, 2014 1:23 am
So these are some general notes that I'm looking into, and figured I should post the critical stuff in one location.
From datasheet found here http://datasheet.octopart.com/STM32F407VGT6-STMicroelectronics-datasheet-10836202.pdf
Pg 65, GPIO pin max current = 25mA, Max also max into the rails is 150mA.(hmmm, what MCU clock rate are we using?)
Pg 71, typical CPU current (adds to the above 150mA rail maximums) ranges from 2mA at 2MHz, to 117mA when hot and 168MHz.
Pg 99, input = high when above 2V, and = low when CMOS pins are below .3V, or when TTL are below .8V. Each pin has 5pF of of internal capacitance.
Pg 121, notes .6V rail diodes.
