4.4. SPI Interface

4.4.1.

Features

TC3567C has the following main features for a serial memory interface



Operation voltage:

1.8 to 3.6 V



SPI interface



Chip select:

1 ch



Chip select polarity:

Selectable: High-active and Low-active



Serial clock master operation: Polarity and phase are adjustable (4 combinations are selectable)



Serial clock frequency:

25 Hz to 6.5 MHz



Serial data transfer mode:

MSB-first, LSB-first

SPI interface can operate at 1.8 to 3.6 V depending on VDDIO, however, cannot operate at different voltage from ones other

interfaces are operate at.
