Design of an Ultra-Low Power Timer System Based on C8051F410

Abstract

This paper proposes an ultra-low power design based on C8051F410 which is used in a timer system for industrial production and device detection failure occurred at a time and the record of relevant information. Two aspects like system hardware circuit and software design of the ultra-low power timer system are demonstrated. This system features low power consumption from the entire system, including the Chinese man-machine interface which consumes only 1mA power cost. This system is suitable for the situations where battery power is limited.

Design of Micro Power Liquid Level Transmitter Based on C8051f410 Chip System

“…In the industrial temperature range (-40℃~+85℃), each device can operate at 2.0~2.75V voltage (the voltage of power supply can reach 5.25V when the on-chip voltage regulator is used). C8051F410 is packaged in LQFP having 32 pins [3]. The converter circuit is shown in Figure 3 and composed of amplifier adjustment circuit, transistor current compensation circuit and so on.…”
