TM-1300 and DSPCPU Core Current and Power Consumption Details
Notes:
1. Consumption for TM-1300 is organized in several categories. Typ. column presents current consumption for a typical appli-
cation with a CPI (Clocks Per Instruction) of 1.4 with all the peripherals units turned on (peripherals run on a random data
pattern and running at the specified frequencies, VO runs at 27 MHz). Max. column provides current consumption for an
application with a CPI of 1.1 with all the peripherals units turned on (peripherals run on a random data pattern and running
at the specified frequencies, VO runs at 27 MHz). This is a dedicated application that heavily uses the DSPCPU and that
does not reflect a real application but does indicate peak currents. Typ. measurements reflect real applications. Pwd. column
indicates current consumption when Global Powerdown mode is activated. See
Chapter 21, “Power Management.”
2. TM-1300 Standby rows indicate current consumption when DSPCPU is maintained under RESET (See
Section 11.7.5,
“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 if the CPU:SDRAM ratio are different. Same ratio must be used.
