XMEGA A3U Table 36-28. t CK t CH t CL External clock with prescaler (1) for system clock. Symbol Parameter Condition Min. Typ. Max. Units Clock Period Clock High Time Clock Low Time V CC = 1.6 - 1.8V 11 V CC = 2.7 - 3.6V 7 V CC = 1.6 - 1.8V 4.5 V CC = 2.7 - 3.6V 2.4 V CC = 1.6 - 1.8V 4.5 V CC = 2.7 - 3.6V 2.4 t CR Rise Time (for maximum frequency) 1.5 t CF Fall Time (for maximum frequency) 1.5 Δt CK Change in period from one clock cycle to the next 10 % Notes: 1. System Clock Prescalers must be set so that maximum CPU clock frequency for device is not exceeded. 2. The maximum frequency vs. supply voltage is linear between 1.8V and 2.7V, and the same applies for all other parameters with supply voltage conditions. ns 8386B–AVR–12/11 84
