• Min / Max characteristics and specifications are guaranteed over all
• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25 °C.
• VA+ = 5 V ±5% VD+ = 3.3 V ±5% or 5 V ±5%; AGND = DGND = 0 V. All voltages with respect to 0 V.
• Logic Levels: Logic 0 = 0 V, Logic 1 = VD+.
PROM mode Timing
18. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an
external clock source.
