MSP430集成电路（IC）的微控制器规格书PDF中文资料

MSP430属于集成电路（IC）的微控制器。由德州仪器制造生产的MSP430微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。

1.3 Description

The TI MSP family of ultra-low-power microcontrollers consists of several devices that feature different

sets of peripherals targeted for various applications. The architecture, combined with five low-power

modes, is optimized to achieve extended battery life in portable measurement applications. The device

features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to

maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from lowpower

modes to active mode in less than 1 μs.

The MSP430G2x03 and MSP430G2x33 devices are ultra-low-power mixed-signal microcontrollers with

built-in 16-bit timers, up to 24 I/O capacitive-touch enabled pins, and built-in communication capability

using the USCI. In addition, the MSP430G2x33 family members have a 10-bit ADC. See Section 3 for

configuration details.

Typical applications include low-cost sensor systems that capture analog signals, convert them to digital

values, and then process the data for display or for transmission to a host system.
