MSP430G2230QDEP

MSP430G2230是超低功耗微控制器。这种架构与5种低功耗模式相组合，专为在便携式测量应用中延长电池使用寿命而优化。该器件具有一个强大的16位RISC CPU，16位寄存器和有助于获得最大编码效率的常数发生器。数字控制振荡器(DCO)可在不到1μs的时间里完成从低功耗模式至运行模式的唤醒。 MSP430G2230是超低功率混合信号微控制器，此微控制器装有一个内置的16位定时器和4个I/O引脚。除此之外，MSP430G2230还有使用同步协议（SPI或者I2C）的内置通信功能和一个10位A/D转换器。 The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand. The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock. Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator, respectively. The remaining registers are general-purpose registers. Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all instructions. The instruction set consists of 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data. The MSP430 has one active mode and five software-selectable low-power modes of operation. An interrupt event can wake the device from any of the five low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program.
