MSP430G2233IPW28R

MSP430 系列超低功耗微控制器包含多种器件，具有面向各种应用的不同外设集。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的使用寿命而进行了优化。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1 µs的时间里完成从低功耗模式至运行模式的唤醒。

MSP430G2x03和MSP430G2x33系列是超低功耗混合信号微控制器，具有内置的16位计时器、最多24个支持触摸感测的I/O引脚、以及采用通用串行通信接口的内置通信能力。此外，MSP430G2x33系列成员还具有一个10位A/D转换器。

典型应用包括低成本传感器系统，此类系统负责捕获模拟信号、将之转换为数字值、随后对数据进行处理以进行显示或传送至主机系统。

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 the original 51 instructions with three formats and seven address modes and additional instructions for the expanded address range. 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 up the device from any of the low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program.
