Description
This application note describes ways to reduce system current consumption with the use of the Ultra Low-power Wake-up (ULPWU) module. Currently, the PIC16F684 has this module, but other low pin count parts will have it as well. The primary use of this module is as an Ultra Low-power Wake-up (ULPWU) timer, but its functionality can be expanded to function as a temperature sensor and/or a low-voltage detector. The main and expanded functions of this module are explained in this document. Many low-power applications require that the microprocessor wake-up from a Sleep state on a periodic basis to check the status of some signal. It can then react depending on a measurement and go back to Sleep until the next timed wake-up. This is a widely used method for reducing overall system current
