Low-Power System-on-a-Chip
6.3 DC Characteristics
All characteristics are specified at VDD = 2.7 V (± 5%) at 13.0 MHz or 3.3 V (± 10%) at 18.432 MHz, and
VSS = 0 V over an operating temperature of 0°C to +70°C. The current consumption figures relate to typ-
ical conditions at 3.3 V, 18.432-MHz operation with the PLL switched on.
