NOTES
1 Bidirectional pins: D0–D31, RFS0, RFS1, SCLK0, SCLK1, TFS0, TFS1, IAD0–15, PF0–PF7.
2 Input only pins: IRQ2, BR, MMAP, BMODE, BUS MODE, BUS SEL, DR0, DR1, PWD, IRQL0, IRQL1, IRQE, IS, IRD, IWR, IAL.
3 Input only pins: CLKIN, RESET, IRQ2, BR, MMAP, BMODE, BUS MODE, BUS SEL, DR0, DR1, PWD, IRQL0, IRQL1, IRQE, IS, IRD, IWR, IAL.
4 Output pins: BG, BGH, PMS, DMSL, DMSH, BMS, IOMS, CMS, RD, WR, IACK, PWDACK, A0–A25, DT0, DT1, CLKOUT, FL2–0.
5 Although specified for TTL outputs, all ADSP-2141L outputs are CMOS-compatible and will drive to VDD and GND, assuming no dc loads.
6 Guaranteed but not tested.
7 Output pins: BG, BGH, PMS, DMSL, BMS, IOMS, DMSH, CMS, RD, WR, IACK, PWDACK, A0–A25, DT0, DT1, CLKOUT, FL2–0, EE_DI, EE_CS, EE_SK.
80 V on BR. CLKIN active (to force three-state condition).
9 Three-statable pins: A0–A25, D0–D31, PMS, DMSL, DMSH, BMS, IOMS, CMS, RD, WR, DT0, DT1, SCKL0, SCLK1, TFS0, TFS1, RFS0, RFS1, IAD0–
IAD15, PF0–PF7.
10 Idle refers to ADSP-2141L state of operation during execution of IDLE Instruction. Deasserted pins are driven to either VDD or GND.
11Current reflects device operating with no output loads.
12 VIN = 0.4 V and 2.4 V. For typical supply currents, refer to Power Dissipation section.
13IDD measurement taken with 93% of instructions executing from internal memory and 7% from external memory. H/E operations are executing from internal
memory concurrently with PCI transactions. Initialization operations are executed from external memory.
14Applies to MQFP package type.
15Output pin capacitance is the capacitive load for any three-stated output pin.
