Notes: 1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the

device. Prolonged exposure to levels above the operating limits but below the Absolute Maximums may affect

device reliability.

External Components

The MK3200 requires a minimum number of external components for proper operation. A decoupling capacitor of

0.01µF should be connected between VDD and GND on pins 2 and 3, as close to the MK3200 as possible. A series

termination resistor of 33 Ω may be used for the clock output if the trace is longer than a few inches. The input crystal

must be connected as close to the chip as possible. The input crystal should be a parallel mode watch crystal with 12

pF load capacitance.
