Description Min Nom Max Min Nom Max VDD_INT 2 2 SVSNOM refers to the nominal SVS voltage which is set between 1.0 V and 1.15 V at the factory for each individual device. Only the unique SVSNOM value in each chip may be used for 401 MHz to 450 MHz operation of that chip. This spec lists the possible range of the SVSNOM values for all devices. The initial VDD_INT voltage at power on is 1.1 V nominal and it transitions to SVS programmed voltage as outlined in Engineer-to-Engineer Note “Static Voltage Scaling for ADSP-2148x Processors” (EE-357). Internal (Core) Supply Voltage 1.05 1.1 1.15 SVSNOM – 25 mV 1.0 – 1.15 SVSNOM + 25 mV V VDD_EXT External (I/O) Supply Voltage 3.13 3.47 3.13 3.47 V VDD_THD Thermal Diode Supply Voltage 3.13 3.47 3.13 3.47 V VIH 3 3 Applies to input and bidirectional pins: ADDR23–0, DATA15–0, FLAG3–0, DAI_Px, DPI_Px, BOOT_CFGx, CLK_CFGx, RUNRSTIN, RESET, TCK, TMS, TDI, TRST, AMI_ACK, MLBCLK, MLBDAT, MLBSIG.
