NOTES
1
All Timing Specifications valid over VDD range of 2.375 V to 2.675 V and VDDIO range of 3.0 V to 3.6 V.
2
C
= 40 pF on all outputs unless otherwise specified.
3
The timing parameters for SCLK, SDFS, SDFE, SDO, SDI, and DR apply to all four channels (0, 1, 2, and 3). The slave serial port’s (SCLK) operating frequency is
limited to 62.5 MHz.
Specifications subject to change without notice.
