1 The expected nominal value is 1.4 V

±5%, and initial customer designs should design with a programmable regulator that can be adjusted from 0.95 V to 1.5 V in 50 mV steps.

4 Bidirectional pins (PF15–0, PG15–0, PH2–0) and input pins (TCK, TDI, TMS, TRST, CLKIN, RESET, NMI, and BMODE3–0) of the ADSP-BF50x processors are 3.3 V tolerant

(always accept up to 3.6 V maximum VIH). Voltage compliance (on outputs, VOH) is limited by the VDDEXT supply voltage.

5 Parameter value applies to all input and bidirectional pins, except SDA and SCL.
