AC Electrical Characteristics
than 10 ns of Cycle to Cycle Variation on CKi
† Characteristics are over recommended operating conditions unless otherwise stated.
‡ Typical figures are at 25°C, VDD_CORE at 1.8 V and VDD_IO at 3.3 V and are for design aid only: not guaranteed and not subject to produc-
tion testing.
