MSP430F4491中文资料具有 60KB 闪存、2KB SRAM、比较器、SPI/UART 和 160 段 LCD 的 8MHz MCU数据手册TI规格书

描述 Description

The Texas Instruments MSP430 family of ultralow power microcontrollers consists of several devices featuring 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 devices feature a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than6 µs.

The MSP430x43x

and the MSP430x44x

series are microcontroller configurations with two built-in 16-bit timers, a fast 12-bit A/D converter (not implemented on the MSP430F43x1 and MSP430F44x1 devices), one or two universal serial synchronous/asynchronous communication interfaces (USART), 48 I/O pins, and a liquid crystal driver (LCD) with up to 160 segments.

Typical applications include sensor systems that capture analog signals, convert them to digital values, and process and transmit the data to a host system, or process this data and display it on a LCD panel. The timers make the configurations ideal for industrial control applications such as ripple counters, digital motor control, EE-meters, hand-held meters, etc. The hardware multiplier enhances the performance and offers a broad code and hardware-compatible family solution.
