SPI - electrical characteristics

VS =6V to 28 V, VCC = 3 V to 5.3 V, Tj = -40°C to 150°C, unless otherwise specified. The

voltages are referred to GND and currents are assumed positive, when the current flows

into the pin.

Table 19. DI timing(1)

DI timing parameters tested in production by a passed / failed test:

Tj = -40°C / +25°C: SPI communication @ 2 MHz.

Tj = +125°C: SPI communication @ 1.25 MHz.
