NOTES
1Bidirectional pins: D0-D23, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, HD0-HD15/HAD0-HAD15.
2Input only pins: RESET, IRQ2, BR, MMAP, DR0, DR1, HSEL, HSIZE, BMODE, HMD0, HMD1, HRD/HWR, HWR/HDS, PWD, HA2/ALE, HA1-0.
3Input only pins: CLKIN, RESET, IRQ2, BR, MMAP, DR0, DR1, HSEL, HSIZE, BMODE, HMD0, HMD1, HRD/HWR, HWR/HDS, PWD, HA2/ALE, HA1-0.
4Output pins: BG, PMS, DMS, BMS, RD, WR, PWDACK, A0-A13, DT0, DT1, CLKOUT, HACK, FL2-0, BGH.
5Although specified for TTL outputs, all ADSP-2171/ADSP-2172 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, RD, WR, DT0, DT1, SCLK0, SCLK1, TFS0, TFS1, RFS0, RSF1, HD0-HD15/HAD0-HAD15.
80 V on BR, CLKIN Active (to force three-state condition).
9Idle refers to ADSP-2171/ADSP-2172 state of operation during execution of IDLE instruction. Deasserted pins are driven to either V DD or GND. Current reflects
device operation with CLKOUT disabled.
10Current reflects device operating with no output loads.
11VIN = 0.4 V and 2.4 V. For typical figures for supply currents, refer to “Power Dissipation” section.
12See Chapter 9, of the ADSP-2100 Family User’s Manual for details.
13Applies to TQFP and PQFP package types.
14Output pin capacitance is the capacitive load for any three-state output pin.
Specifications subject to change without notice.
