5.3.2 Digital I/O level shifter
All the SCA3000 products have an internal level shifter that can be used to interface e.g. a micro
controller using lower supply than the SCA3000. The level shifter is "programmed" by providing the
supply voltage of the interfaced device to the DVIO-pin. Please refer to the corresponding product
data sheet for details.
5.3.3 SPI AC characteristics
The AC characteristics of the SCA3000 SPI interface are defined in Figure 11 and in Table 21.
