MSP430FR2000 and MSP430FR21xx devices are part of the MSP430™ microcontroller (MCU) value line sensing portfolio. This ultra-low-power, low-cost MCU family offers memory sizes from 0.5KB to 4KB of FRAM unified memory with several package options including a small 3-mm×3-mm VQFN package. The architecture, FRAM, and integrated peripherals, combined with extensive low-power modes, are optimized to achieve extended battery life in portable, battery-powered sensing applications. MSP430FR2000 and MSP430FR21xx devices offer a migration path for 8-bit designs to gain additional features and functionality from peripheral integration and the data-logging and low-power benefits of FRAM. Additionally, existing designs using MSP430G2x MCUs can migrate to the MSP430FR2000 and MSP430F21xx family to increase performance and get the benefits of FRAM.

The MSP430FR2000 and MSP430FR21xx MCUs feature a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) also allows the device to wake up from low-power modes to active mode typically in less than 10 µs. The feature set of this MCU meets the needs of applications ranging from appliance battery packs and battery monitoring to smoke detectors and fitness accessories.

The MSP ultra-low-power (ULP) FRAM microcontroller platform combines uniquely embedded FRAM and a holistic ultra-low-power system architecture, allowing system designers to increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the nonvolatile behavior of flash.

MSP430FR2000 and MSP430FR21x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get your design started quickly. Development kits include the MSP-EXP430FR2311 and MSP430FR4133 LaunchPad™ development kit and the MSP‑TS430PW20 20-pin target development board. TI also provides free MSP430Ware™ software, which is available as a component of Code Composer Studio™ IDE desktop and cloud versions within TI Resource Explorer. MSP430 MCUs are also supported by extensive online collateral, such as our housekeeping example series, MSP Academy training, and online support through the TI E2E™ support forums.

For complete module descriptions, see the MSP430FR4xx and MSP430FR2xx Family User’s Guide.

參考設計

TIDA-00847 — 採用具有整合電源的數位隔離器且尺寸和成本經最佳化的二進位模組參考設計

此參考設計僅使用兩種產品簡化系統設計，為 4 通道 DC 輸入二進位模組展示空間與成本最佳化架構，並具備改良的測量準確度與狀態指示。MCU 型二進位模組可改善二進位輸入的量測解析度，進而提升系統性能，提供準確且可重複的故障指示，並可省去對多個硬體版本的需求 (對多個額定電壓輸入使用相同設計)。這減少了設計、測試、製造和現場支援工作。在此設計中，4 輸入通道配置為群組隔離輸入，以將每通道成本降到最低。10 位元類比轉數位轉換器 (ADC)，可在廣泛範圍中測量 ±3% ±1-V 範圍內的 DC 輸入準確度。已針對 EMI 和 EMC 執行預先相容測試。
