Electrical specifications

2.5

SPI - electrical characteristics

VS = 6 V 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.

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.
