NOTES
1
Bidirectional pins: D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7.
2
Input only pins: RESET , BR, DR0, DR1, PWD.
3
Input only pins: CLKIN, RESET, BR , DR0, DR1, PWD.
4
Output pins: BG, PMS, DMS, BMS, IOMS , CMS, RD, WR, PWDACK, A0, DT0, DT1, CLKOUT, FL2–0, BGH .
5
Although specified for TTL outputs, all ADSP-2186 outputs are CMOS-compatible and will drive to V
DD
and GND, assuming no dc loads.
6
Guaranteed but not tested.
7
Three-statable pins: A0–A13, D0–D23, PMS, DMS, BMS , IOMS, CMS, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RFS1, PF0–PF7.
8
0 V on BR, CLKIN Inactive.
9
Idle refers to ADSP-2186 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.

IN
= 0 V and 3 V. For typical figures for supply currents, refer to Power Dissipation section.
12
Output pin capacitance is the capacitive load for any three-stated output pin.
