说明

Texas Instruments 的 MSP430F5324IRGCR 是一款 16 位超低功耗 MSP430 MCU，采用 64 引脚 VQFN（9×9 mm）封装。主要规格包括 25-MHz CPU、64-KB 闪存、6-KB SRAM、12 位 SAR ADC（10 通道）、8 个比较器、硬件乘法器（32 位）、3 通道 DMA、2 个 USCI 模块（每个模块支持 UART/SPI 和 I2C）、4 个 16 位定时器（Timer_A ×3、Timer_B ×1）、47 个 GPIO 和带报警功能的 RTC。工作电压为 1.8 V 至 3.6 V。功耗：290 µA/MHz（激活）（闪存）、1.9 µA（待机）（带 RTC 的 LPM3）、0.18 µA（关机）（LPM4.5），待机唤醒时间为 3.5µs。工业温度范围 -40°C 至 +85°C。.

MSP430F5324 是德州儀器 MSP430F532x 系列超低功耗 16 位元混合訊號微控制器的成員。5324 ‘变体采用 64 引脚 VQFN 封装，提供 64KB 闪存、6KB SRAM 和 47 个 I/O 引脚，是介于较小的 28 引脚和较大的 80 引脚系列产品之间的中端器件。.

MSP430 架构通过灵活的时钟管理、多种低功耗模式和集成 LDO 的组合，对低功耗运行进行了优化。统一的时钟系统包括用于快速唤醒（待机 3.5 µs）的数字控制振荡器 (DCO)、用于稳频的 FLL、用于 RTC 的 32 kHz 晶体振荡器 (XT1) 以及高达 32 MHz 的高频晶体振荡器 (XT2)。片上 LDO 可调节内核电源，使器件能在 1.8 V 至 3.6 V 单电源下运行。.

五种低功耗模式是 MSP430 的标志。激活模式的闪存功耗为 290 µA/MHz（RAM 功耗为 150 µA/MHz）。LPM3（待机模式，RTC、WDT 和电源监控器处于激活状态）在 2.2 V 电压下仅消耗 1.9 µA。LPM4（关机模式，保留 RAM 和电源监控器）电流为 1.1 µA。LPM4.5（关机模式，无 RAM 保留）的电流仅为 0.18 µA - 接近纽扣电池的自放电率。.

两个 USCI 模块分别支持双协议操作：USCI_A 提供 UART（带自动波特检测）和 SPI，而 USCI_B 提供 I2C 和 SPI。这样就可以同时使用 UART + I2C 或 SPI + I2C 或任意组合。12 位 ADC 包括内部基准、采样和保持以及自动扫描，可在无需 CPU 干预的情况下进行连续通道采样。.

硬件乘法器支持在一个指令周期内进行 32 位运算（32×32 → 64 位结果），从而加速了类似 DSP 的算法。3 通道 DMA 可卸载 CPU 的存储器传输，实现 ADC 到 RAM 或 UART 到 RAM 的传输，CPU 开销为零。.

典型应用包括电池供电的数据记录器、无线传感器节点、便携式医疗仪器和智能计量系统，在这些应用中，超低静态电流和快速唤醒对于延长电池寿命至关重要。.

**MSP430 CPU 内核：** MSP430 采用 16 位 RISC 架构，带有 16 位寄存器和常量发生器，可实现高效指令编码。27 条内核指令可处理大多数操作；额外的仿真指令可提供便利。Von Neumann 架构为闪存、SRAM 和外设使用单一地址空间。CPU 运行速度高达 25 MHz，可进行单周期寄存器到寄存器操作。.

**统一时钟系统（UCS）：** UCS 管理四个时钟源：XT1（32 kHz 晶体）、XT2（高频晶体，高达 32 MHz）、DCO（数字控制振荡器，快速启动）和 VLO（低频内部时钟，典型值为 10 kHz）。FLL 倍增 32 kHz 基准，以产生稳定的 MCLK 和 SMCLK。DCO 在微秒内启动，从而实现了 3.5µs 的 LPM3 唤醒时间。.

**低功耗模式：** 五种低功耗模式在功能与功耗之间进行权衡。LPM0 保持 SMCLK 运行（基于定时器的事件）。LPM3 仅保持 ACLK（32 kHz）和 RTC 处于活动状态（定期唤醒）。LPM4 关闭所有时钟，但保留 SRAM（中断唤醒）。LPM4.5 完全禁用 LDO，丢失 SRAM 内容，但实现了 0.18 µA（复位唤醒）。关键设计原则：大部分时间处于深度睡眠状态，短暂唤醒以进行测量，然后返回睡眠状态。.

**USCI 通信：** 每个 USCI 模块都使用共享移位寄存器，并为 UART 和 I2C/SPI 模式配备独立的波特率发生器。在协议之间切换需要重新配置，但不需要更改硬件。UART 支持未知波特率的自动波特检测。I2C 支持具有多主仲裁和时钟扩展功能的主/从协议。.
