Bidirectional pins: D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, A1–A13, PF0–PF7.
Input only pins: RESET, BR, DR0, DR1, PWD.
Input only pins: CLKIN, RESET, BR, DR0, DR1, PWD.
Output pins: BG, PMS, DMS, BMS, IOMS, CMS, RD, WR, PWDACK, A0, DT0, DT1, CLKOUT, FL2-0, BGH.
Although specified for TTL outputs, all ADSP-2186 outputs are CMOS-compatible and will drive to V
Guaranteed but not tested.
Three-statable pins: A0–A13, D0–D23, PMS, DMS, BMS, IOMS, CMS, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RSF1, PF0–PF7.
0 V on BR, CLKIN Inactive.
Idle refers to ADSP-2181 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
I
and type 6, and 20% are idle instructions.
V
Applies to TQFP and PQFP package types.
Output pin capacitance is the capacitive load for any three-stated output pin.
