NOTES
1The ADSP-2189M is 3.3 V tolerant (always accepts up to 3.6 Volt max V
IH), but voltage compliance (on outputs, V OH) depends on the input VDDEXT; because VOH
(max)
≈ V
DDEXT (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).

RESET, BR, DR0, DR1, PWD.
4Output pins:
BG, PMS, DMS, BMS, IOMS, CMS, RD, WR, PWDACK, A0, DT0, DT1, CLKOUT, FL2-0, BGH.
5Although specified for TTL outputs, all ADSP-2189M outputs are CMOS-compatible and will drive to V
DDEXT and GND, assuming no dc loads.
6Guaranteed but not tested.
7Three-statable pins: A0–A13, D0-D23,
PMS, DMS, BMS, IOMS, CMS, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RFS1, PF0–PF7.

BR.
9Idle refers to ADSP-2189M state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD or GND.
10 I
DD 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
IN = 0 V and 3 V. For typical figures for supply currents, refer to Power Dissipation section.
12 See Chapter 9 of the ADSP-2100 Family User’s Manual, Third Edition for details.
13 Applies to LQFP package type.
14 Output pin capacitance is the capacitive load for any three-stated output pin.
