CURRENT CONSUMPTION BY OPERATING MODE
parameters. To make this data more usable, the values
presented in Table 9 were derived under the conditions
presented 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 I/O loads at maximum (50 pF)
• All voltages at maximum specified values
• Maximum specified ambient temperature.
Typical
using a ‘typical’ application under ‘typical’ environmental
conditions and the following operating characteristics:
• SPI, UART, PWMs, and Timer peripherals operat-
• LCD enabled with 320 × 240 × 16-bit color, 60 Hz
• I/O loads at nominal
• Cache enabled
• FCLK = 77.4 MHz; HCLK = 51.6 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 deter-
mined with the peripheral clock running at maximum
frequency, typical conditions, and no I/O loads.
