NOTES
1Bidirectional pins: D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7.
2Input only pins:
RESET, BR, DR0, DR1, PWD.
3Input only pins: CLKIN,
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-2186 outputs are CMOS-compatible and will drive to V
DD 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.
80 V on
BR, CLKIN Inactive.
9Idle refers to ADSP-2186 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD or GND.
10I
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.
11V
IN = 0 V and 3 V. For typical figures for supply currents, refer to Power Dissipation section.
12Output pin capacitance is the capacitive load for any three-stated output pin.
Specifications subject to change without notice.
