The regulator can generate V
DDINT
at levels of 0.85 V to 1.2 V with –5% to +10% tolerance, 1.25 V with –4% to +10% tolerance, and 1.3 V with –0% to +10% tolerance.

When V
DDEXT
< 2.25 V, on-chip voltage regulation is not supported.

Applies to all input and bidirectional pins except CLKIN.

The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are 3.3 V tolerant (always accepts up to 3.6 V maximum V
IH
), but voltage compliance (on outputs, V
OH
) depends on
the input V
DDEXT
, because V
OH
(maximum) approximately equals V
DDEXT
(maximum). This 3.3 V tolerance applies to bidirectional pins (DATA15–0, TMR2–0, PF15–0, PPI3–0,
RSCLK1–0, TSCLK1–0, RFS1–0, TFS1–0, MOSI, MISO, SCK) and input only pins (BR, ARDY, PPI_CLK, DR0PRI, DR0SEC, DR1PRI, DR1SEC, RX, RTXI, TCK, TDI, TMS,
TRST, CLKIN, RESET, NMI, and BMODE1–0).
6
Applies to CLKIN pin only.
7
Applies to all input and bidirectional pins.
