2. Electrical Characteristics

Note 1. Supply current values are with all output pins unloaded and all input pull-up MOS transistors in the off state.

Note 2. Measured with clocks supplied to the peripheral functions. This does not include the BGO operation.

Note 3. This does not include the BGO operation.

Note 4. Supply of the clock signal to peripherals is stopped in this state. This does not include the BGO operation.

Note 5. When VBATT is used.

Note 6. When using ETHERC, PCLKA frequency is:

12.5MHz ≤ PCLKA ≤ 120MHz

Note 7. When VCC is < VDETBATT and > (VBATT + 0.6 V), the injected current connects from the VCC to the VBATT

pin through an internal diode.

Table 2.9

Rise and fall gradient and ripple frequency characteristics

The ripple voltage must meet the allowable ripple frequency fr(VCC) within the range between the VCC upper limit (3.6 V) and lower limit

(2.7 V). When the VCC change exceeds VCC ±10%, the allowable voltage change rising and falling gradient dt/dVCC must be met.
