MSP430×32×系列超低功耗单片机是美国德州仪器公司近期产品,其中有MSP430C323(8KB ROM、256字节RAM),MSP430C325(16KB ROM、512字节RAM),MSP430P325(16KBOTP、512字节RAM)等型号的单片机。这些单片机具有低电源电压范围较宽(2.5～5.5V),工作电流低(在3V、1MHz情况下为400μA)和超低功耗(备用状态模式时小至0.1μV)等优点。它们采用5种储电节能模式,在6μs时间内能完成备用状态模式的激活;拥有多达84段的LCD驱动电路,保证显示的清晰度;在使用单个32kHz普通晶振的条件下能使其内部系统时钟高达3.3MHz,保证高性能的实现;具有16位RISC结构和300μs的指令周期时间,能保证达到最大的编码效率。 MSP430×32×系列超低功耗单片机可应用于传感器系统,实现工业控制和检测,也可用于仪器、仪表及通信等领域。
MSP430 × 32 × series of ultra-low-power microcontrollers are Texas Instruments recent products, including MSP430C323 (8KB ROM, 256 bytes RAM), MSP430C325 (16KB ROM, 512 bytes RAM), MSP430P325 (16KBOTP, 512 bytes RAM ) And other models of SCM. These microcontrollers offer the benefits of low supply voltage (2.5-5.5V), low operating current (400μA at 3V, 1MHz) and ultra-low power (as small as 0.1μV in standby mode). They use five kinds of energy-saving mode, in 6μs time to complete the standby mode activation; has up to 84 segments of the LCD driver circuit to ensure the clarity of display; In the use of a single 32kHz ordinary crystal under internal conditions System clock up to 3.3MHz, to ensure high performance; with 16-bit RISC structure and 300μs instruction cycle time, to ensure maximum coding efficiency. MSP430 × 32 × series of ultra-low-power microcontrollers can be applied to the sensor system for industrial control and testing, but also for instruments, meters and communications.
