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 VDD=3.3V, processor clock at 60MHz, and ACLK at 12.288MHz.
External Components
The MK2745-24 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.1F should be connected between VDD and GND (on pins 4 and 5, and pins 13 and 12),
as close to the MK2745-24 as possible. A series termination resistor of 33
may be used for each clock
output. If a clock input is not used, the 27.00 MHz crystal must be connected as close to the chip as
possible. The crystal should be a fundamental mode (do not use third overtone), parallel resonant, 50ppm
or better. Crystal capacitors should be connected from pins X1 to ground and X2 to ground. The value of
these capacitors is given by the following equation, where CL is the crystal load capacitance: Crystal caps
(pF) = (CL-6) x 2. So for a crystal with 16pF load capacitance, two 20pF caps should be used.
