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 V during ramp-up until 2.5V is reached, at which time it self-regulates.

10.2.1 Voltage Regulator Specifications
The 56F8036 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 2.5V to the 56F8036’s core logic. This
regulator requires an external 4.4µF, or greater, capacitor for proper operation. Ceramic and tantalum
