9.0
Certain special circuits that deal with the needs of real
time applications are what sets a microcontroller apart
from other processors. The PIC16F630/676 family has
a host of such features intended to:
• maximize system reliability
• minimize cost through elimination of external
• provide power-saving operating modes and offer
These features are:
• Oscillator selection
• Reset
• Interrupts
• Watchdog Timer (WDT)
• Sleep
• Code protection
• ID Locations
• In-Circuit Serial Programming™

SPECIAL FEATURES OF THE
CPU
The PIC16F630/676 has a Watchdog Timer that is
controlled by Configuration bits. It runs off its own RC
oscillator for added reliability. There are 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 72 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
device if a brown-out occurs, which can provide at least
a 72 ms Reset. With these three functions on-chip,
most applications need no external Reset circuitry.
The Sleep mode is designed to offer a very low current
Power-down mode. The user can wake-up from Sleep
through:
• External Reset
• Watchdog Timer wake-up
• An interrupt
Several oscillator options are also made available to
allow the part to fit the application. The INTOSC option
saves system cost while the LP crystal option saves
power. A set of Configuration bits are used to select
various options (see Register 9-1).
