PIC Microcontroller in Mobile Phone Remote Controller Low Power Design Abstract: The combination of telephone remote controller for low-power design to explore the PIC single-chip low-power design methodology, and give the design of the circuit schematic.  Keywords: PIC Single-chip low-power design telephone remote controller standby INTRODUCTION 20th century since the 90s, with the characteristic line width of integrated circuits continue to shrink and the chip density and a corresponding increase in operating frequency, lower power consumption has become a sub-micron and deep sub-micron VLSI design of a major consideration in factors. The increase in power will bring about a series of questions, such as the circuit parameters drift, reliability decreased chip package increase in production costs. Therefore, the system power consumption in the entire system design, especially in the use of battery-powered system, it is very important. Microchip Inc. PIC microcontroller series for the design of high-performance, low-power single-chip microcomputer system provided a good solution. The following from the low-power design methods and specific examples to introduce single-chip low-power applications PIC. One low-power design methodology To make the system work in the low-power state, must be properly set up single-chip configuration and work. The following combination of the most commonly used PIC12, PIC16, etc. Introduce Single-chip low-power system design. 1.1 The basic design method Have much technology can reduce system power consumption, the most commonly used are Sleep mode. Procedures for the enforcement of a SLEEP instruction, then entered a dormant (Sleep) mode. To Sleep mode, the crystal oscillation to stop, at which point single-chip microcomputer in the 3V power supply conditions, only 1μA of current. System work, can be used single-chip watchdog or external events periodically wake-up single-chip, the electronic switch to provide power for t
