MSP430FR2311IPW20 Technical Specifications

MSP430FR2311IPW20 Key Features

• Single 16?bit MSP430 core offering efficient instruction execution and low active current for longer battery life.
• On?chip FRAM memory enabling thousands to millions of immediate writes with low energy per write, which matters for frequent data logging.
• Low operating range of 1.8 V to 3.6 V, enabling compatibility with single?cell Li?ion and common coin cell systems for simpler power management.
• Compact 20?pin package that reduces board area and BOM compared with larger MCU packages while still providing flexible I/O and timers.

Typical Applications

• Battery?powered sensors and data loggers where frequent nonvolatile writes and long battery life are required over extended deployments.
• Industrial control nodes that need reliable nonvolatile state retention and low?power sleep modes for remote or distributed systems.
• Portable medical devices that require a compact package, low supply voltage operation, and frequent data capture without flash wear concerns.
• Consumer wearable interfaces where small form factor and efficient on?chip FRAM enable rapid state saving and robust power cycling behavior.

MSP430FR2311IPW20 Advantages vs Typical Alternatives

The device uses on?chip FRAM rather than NOR or embedded flash, which provides faster writes, lower energy per write, and higher endurance versus typical flash?based MCUs. Its 16?bit MSP430 core yields lower active current than many 32?bit alternatives when performing comparable control tasks. The 20?pin package makes it smaller than many 28?pin contenders, while the stated 1.8?C3.6 V range supports more battery chemistries. For designs prioritizing frequent nonvolatile updates, minimal sleep wake overhead, and compact PCB footprint, this part delivers clear integration and efficiency benefits.
