MSP430FR6927IRGCT Key Features
- FRAM non-volatile memory delivering faster, higher-endurance writes than flash; it matters for frequent data logging and configuration storage.
- 16-bit RISC core with deterministic execution for efficient control code and lower cycle counts compared with many 8-bit options.
- Low-voltage operation from 1.8 V to 3.6 V, enabling compatibility with single-cell lithium and common industrial supplies for broader design flexibility.
- Integrated analog and serial peripherals (12-bit ADC, eUSCI for UART/SPI/I2C) that reduce external component count and speed integration.
- Multiple low-power modes to optimize active versus standby energy use, improving battery life in portable and energy-sensitive applications.
- Compact 48-pin QFN package for denser board layouts while keeping significant I/O and peripheral routing available.
Typical Applications
- Battery-powered sensors and data loggers that need frequent non-volatile writes and long-term data retention with lower energy per write than flash-based solutions.
- Industrial metering and control nodes that require deterministic 16-bit control, reliable non-volatile settings storage, and robust serial connectivity for field buses.
- Portable medical and handheld devices that benefit from low-voltage operation, compact packaging, and integrated ADCs for analog sensing and monitoring.
- Consumer or building automation endpoints that demand low standby current, rapid wake-up, and field-programmable memory for firmware updates and configuration changes.
MSP430FR6927IRGCT Advantages vs Typical Alternatives
The MSP430FR6927IRGCT pairs FRAM endurance and write speed with a proven 16-bit core to deliver lower system power and faster non-volatile updates versus flash-based microcontrollers. Designers get more reliable data logging and more write cycles without external EEPROM. The integrated 12-bit ADC, timers, DMA, and multi-protocol eUSCI modules reduce BOM count compared with MCU-plus-peripheral discrete solutions. The industrial voltage and temperature ranges make it a compact, lower-power alternative for embedded control and sensing applications.
