10.2.1
The 56F8014 has two on-chip regulators. One supplies the PLL and relaxation oscillator. It has no external
pins and therefore has no external characteristics which must be guaranteed (other than proper operation
of the device). The second regulator supplies approximately 2.5 V to the 56F8014’s core logic. This
regulator requires an external 2.2 μF, or greater, capacitor for proper operation. Ceramic and tantalum
capacitors tend to provide better performance tolerances. The output voltage can be measured directly on
the V
10.3 AC Electrical Characteristics
Tests are conducted using the input levels specified in
propagation delays are measured from the 50% to the 50% point, and rise and fall times are measured
between the 10% and 90% points, as shown in

power is ramping up, this signal remains active for as long as the internal 2.5V is below 2.15V or the 3.3V
1/O voltage is below 2.7V, no matter how long the ramp-up rate is. The internally regulated voltage is
typically 100mV less than V
