CURRENT CONSUMPTION BY OPERATING MODE
of parameters. To make these data more usable, the
values presented in Table 11 were derived under the
conditions described here.
Maximum Specified Value
determined using these operating characteristics:
• All IP blocks either operating or enabled at maximum
• Core operating at maximum power configuration
• All voltages at maximum specified values
• Nominal specified ambient temperature.
Typical
using a ‘typical’ application under ‘typical’ environmental
conditions and the following operating characteristics:
• LINUX operating system running from SDRAM
• UART and AC97 peripherals operating; all other
• LCD enabled with 320 × 240 × 16-bit color, 60 Hz
• I/O loads at nominal
• Cache enabled
• FCLK = 200; HCLK = 100; PCLK = 50 MHz
• All voltages at typical values
• Nominal case temperature.

PERIPHERAL CURRENT CONSUMPTION
10 shows the typical current consumption for each
of the on-board peripheral blocks. The values were
determined with the peripheral clock running at 200
MHz, typical conditions, and no I/O loads. This current
is supplied by the 1.8 V power supply.
