Electrical Specifications
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.
2. With 2XCPU clock at 66.66MHz, and BCLK at 33.33MHz

External Components
The MK1432/4 requires a minimum number of external components for proper operation. Decoupling capacitors of
0.1F should be connected between VDD and GND, as close to the MK1432/4 as possible. A series termination
resistor of 33
may be used for each clock output. The device does not require (nor do we recommend) capacitors
connected to the crystal pins. The 14.31818 MHz crystal must be connected as close to the chip as possible.
Recommended load capacitance for the crystal is 12pF.
