NOTES
1
The ADSP-2189M is 3.3 V tolerant (always accepts up to 3.6 Volt 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
).

Idle refers to ADSP-2189M state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
or GND.
10
I
measurement taken with all instructions executing from internal memory. 50% of the instructions are multifunction (types 1, 4, 5, 12, 13, 14), 30% are type 2
and type 6, and 20% are idle instructions.
11
V
= 0 V and 3 V. For typical figures for supply currents, refer to Power Dissipation section.

See Chapter 9 of the
ADSP-2100 Family User’s Manual
, Third Edition for details.
13
Applies to LQFP package type.
