available ever before for microcontrollers. Using the familiar 12-bit opcode width of the PIC16C5X family with the same TMR0 module, Device Reset Timer, and WatchDog Timer (WDT), the PIC12C5XX family adds an internal 4MHz oscillator main clock, serial programming, wake-up on change, user selectable weak
Low Power Design Using PICmicro TM Microcontrollers
techniques are used to reduce power consumption in the PICmicro devices. The most commonly used methods are SLEEP Mode and external events. These modes are the best way to reduce I PD in a system. The PICmicro device can periodically wake-up from Sleep using the Watchdog Timer or external interrupt, execute
