Doc ID 022637 Rev 2

The maximum SPI clock frequency can be calculated as follows (see Figure 18):

tCLKQV(total) = tCLKrise(µC) + tCLKfilt(PCB) + tCLKQV(slave) + tsetup(µC)

fCLK(max) < ½ x tCLKQV(total)

Example:

tCLKQV = 25 ns + 100 ns + 250 ns + 25 ns = 400 ns

fCLK(max) < 1.25 MHz

Input PWM2 for Flash mode

The voltages are referred to ground and currents are assumed positive, when the current

flows into the pin. 6 V

 V

S  18 V; all outputs open; Tamb = -40 °C...125 °C, unless

otherwise specified.
