Product Summary
The PIC16F884-I/PT is an 8 bit CMOS microcontroller. The PIC16F884-I/PT has two timers that offer necessary delays on power-up. One is the Oscillator Start-up Timer (OST), intended to keep the chip in Reset until the crystal oscillator is stable. The other is the Power-up Timer (PWRT), which provides a fixed delay of 64 ms (nominal) on power-up only, designed to keep the part in Reset while the power supply stabilizes. There is also circuitry to reset the PIC16F884-I/PT if a brown-out occurs, which can use the Powerup Timer to provide at least a 64 ms Reset. With these three functions-on-chip, most applications need no external Reset circuitry.
