The PIC16C672 has a host of features intended to maximize system reliability, minimize cost through elimination of external components, provide power saving features and offer code protection against Read Out Heximal of Microcontroller PIC16C672.
These features are:
• Reset
– Power-on Reset (POR)
– Power-up Timer (PWRT)
– Oscillator Start-up Timer (OST)
– Brown-out Reset (BOR)
• Interrupts
• Watchdog Timer (WDT)
• Oscillator Selection
• Sleep
• Code Protection again MCU Crack
• ID Locations
• In-Circuit Serial Programming™
The PIC16C672 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 in the process of Extract Code From Protected Microcontroller DsPIC30F3012. 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 device if a brown-out occurs, which can use the Power-up Timer to provide at least a 64 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 to faciliate the procedures of Copy Eembedded Firmware Of Secured MCU DsPIC30F3011. A set of configuration bits are used to select various options.
The configuration bits can be programmed (read as ‘0’), or left unprogrammed (read as ‘1’) to select various device configurations.
These bits are mapped in program memory location 2007h. Address 2007h is beyond the user program memory space. It belongs to the special configuration memory space (2000h-3FFFh), which can be accessed only during programming.
