MK2745-21
External Components
The MK2745-21 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 MK2745-21 as possible.
A series termination resistor of 33
may be used for each clock output. If a clock input is not used, the 27
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, 50 ppm 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 16
pF load capacitance, two 20 pF caps should be used.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK2745-21. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
