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-2186L 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-2186L state of operation during execution of IDLE instruction. Deasserted pins are driven to either V DD or GND.}
10_{IDD 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_{VIN = 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.}
Specifications subject to change without notice.
