PNX1300/01/02
DSPCPU Core Current and Power Consumption
Notes:
1. Consumption for PNX1300/01/02 is organized in several categories. The
“
Typ
”
column shows current consumption for a typ-
ical application with a CPI (Clocks Per Instruction) of 1.4. The
“
Max
”
column provides current consumption for an application
with a CPI of 1.1. The measurements were taken with all the peripheral units turned on (peripherals run on a random data
pattern at the specified frequencies, except for VO which runs at 27 MHz). This
“
Max
”
data represnts an application that
heavily uses the DSPCPU and does not reflect a realistic application; it is used to determine peak currents. The
“
Typ
”
mea-
surements reflect real applications. The
“
Pwd
”
column shows current consumption when Global Powerdown mode is acti-
vated. See
Chapter 21,
“
Power Management.
”
2. Standby rows indicate current consumption when DSPCPU is maintained under RESET (See
Section 11.6.5,
“
BIU_CTL
Register
”
), all peripherals turned off (i.e. not enabled) and all peripherals powered down (+ bpwd row).
3. Measurements accuracy is +/- 5%. Measurements are done with Vdd set to 2.5V and Vcc set to 3.3V.
4. Currents do not scale with frequency unless the CPU to SDRAM ratio is maintained. As an example, the data for CPU to
SDRAM ratio 1:1 for 183:183 MHz can be calculated by using the data from the 143:143 MHz column, and scaling the cur-
rents by a factor of 1.279.

PNX1311
DSPCPU Core Current and Power Consumption Details
Notes:
1. Consumption for PNX1311 is organized in several categories. The
“
Typ
”
column shows current consumption for a typical
application with a CPI (Clocks Per Instruction) of 1.4. The
“
Max
”
column provides current consumption for an application with
a CPI of 1.1. The measurements were taken with all the peripheral units turned on (peripherals run on a random data pattern
at the specified frequencies, except for VO which runs at 27 MHz). This
“
Max
”
data represnts an application that heavily uses
the DSPCPU and does not reflect a realistic application; it is used to determine peak currents. The
“
Typ
”
measurements
reflect real applications. The
“
Pwd
”
column shows current consumption when Global Powerdown mode is activated. See
Chapter 21,
“
Power Management.
”
2. Standby rows indicate current consumption when DSPCPU is maintained under RESET (See
Section 11.6.5,
“
BIU_CTL
Register
”
), all peripherals turned off (i.e. not enabled) and all peripherals powered down (+ bpwd row).
3. Measurements accuracy is +/- 5%. Measurements are done with Vdd set to 2.2V and Vcc set to 3.3V.
4. Currents do not scale with frequency unless the CPU to SDRAM ratio is maintained.
