Notes
These measurements were taken
after the processor executed the
"stop" instruction and before an
external interrupt was detected.
These measurements were taken
while the processor was in a loop
continuously reading from external
SRAM.
These measurements were taken
while running in SDRAM on the
M5272C3 evaluation board with the
instruction cache on. The sample
applications run during the power
analysis are provided in the
MCF5272 Software Examples
package on the MCF5272 website.
All of the above measurements were taken on a 2K75N mask MCF5272 running at 66 MHz at room
temperature. The current and voltage measurements are for all Vdd on the MCF5272 only (no off-chip
peripherals). These measurements reflect the TYPICAL case only.
