NOTES
1 Bidirectional pins: D0–D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, IAD0–IAD15, PF0–PF7.
2 Input only pins: RESET, IRQ2, BR, MMAP, DR0, DR1, PWD, IRQL0, IRQL1, IRQE, IS, IRD, IWR, IAL.
3 Input only pins: CLKIN, RESET, IRQ2, BR, MMAP, DR0, DR1, IS, IAL, IRD, IWR, IRQL0, IRQL1, IRQE, PWD.
4 Output pins: BG, PMS, DMS, BMS, IOMS, CMS, RD, WR, IACK, PWDACK, A0-A13, DT0, DT1, CLKOUT, FL2-0.
5 Although specified for TTL outputs, all ADSP-2183 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, RSF1, IAD0–IAD15, PF0–PF7.
8 0 V on BR, CLKIN Active (to force three-state condition).
9 Idle refers to ADSP-2183 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V
DD
or GND.
10 Current reflects device operating with no output loads.
11 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.
12 V
IN
= 0.4 V and 2.4 V. For typical figures for supply currents, refer to “Power Dissipation” section.
13 Applies to TQFP and PQFP package types.
14 Output pin capacitance is the capacitive load for any three-stated output pin.
