Voltage Regulator Specifications
The 56F8013/56F8011 have 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 2.5V to the 56F8013/56F8011’s
core logic. This regulator requires an external 2.2μF, 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 VCAP pin. The specifications for this regulator are shown in Table 10-8.
10.3 AC Electrical Characteristics
Tests are conducted using the input levels specified in Table 10-5. Unless otherwise specified,
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 Figure 10-2.

Power-On Reset3
3. Power-On Reset occurs whenever the internally regulated 2.5V digital supply drops below 1.8V. While
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 VDD during ramp-up until 2.5V is reached, at which time it self-regulates.
