NOTES
1
The ADSP-2186M is 3.3 V tolerant (always accepts up to 3.6 V max V
), but voltage compliance (on outputs, V
) depends on the input V
; because V
(max)
≈
V
(max). This applies to bidirectional pins (D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7) and input only pins (CLKIN,
RESET
,
BR
, DR0, DR1,
PWD
).
Specifications subject to change without notice.
