5 The ADSP-BF531/ADSP-BF532 processors are 3.3 V tolerant (always accepts up to 3.6 V maximum VIH), but voltage compliance (on outputs, VOH) depends on the input
V
DDEXT, becauseVOH (maximum)approximatelyequalsVDDEXT (maximum). This3.3Vtoleranceappliestobidirectionalpins(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 Parameter value applies to all input and bidirectional pins except CLKIN.
7 Parameter value applies to CLKIN pin only.
8 Parameter value applies to all input and bidirectional pins.
