Module specifications

2.4

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 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

ports.
