Communication interface characteristics

2.4.1

SPI - serial peripheral interface

Subject to general operating conditions for Vdd and Top.

Figure 3.

SPI slave timing diagram

Note:

Values are guaranteed at 10 MHz clock frequency for SPI with both 4 and 3 wires, based on

characterization results, not tested in production.

Measurement points are done at 0.2·Vdd_IO and 0.8·Vdd_IO, for both Input and output port.

When no communication is on-going, data on CS, SPC, SDI and SDO are driven by internal

pull-up resistors.
