Design of the Circuit Control System for Intelligent Card Heat Meter Based on MSP430 Microcontroller

提出了一种基于MSP430系列单片机的智能IC卡热量表电控系统设计,论述了智能IC卡热量表的控制模式、电控系统电路构成、系统软件设计。为了有效地降低功耗,电控系统的外围电子元器件以低压、低频、静态低功耗的CMOS器件构成;对于系统软件,则在低功耗、信息安全、抗干扰及可靠性等方面进行了设计。系统整体的功耗很低,且运行稳定可靠、操作方便、抗干扰能力强。

Based on the MSP430 Microcontroller,the design of circuit control system for Intelligent Card Heat Meter is propsed,in which the control mode of IRQ is adopted..In order to effectively reduce the power consumption, the electron parts in the circuit control system are composed of low voltage, low frequency, low static power consumption CMOS components. Meanwhile, in the design of corresponding system software special attentions were paid to the low-power consumption, information safety, anti-disturbance and reliability.
