MSP430FR2311IPW20R Technical Specifications

MSP430FR2311IPW20R Key Features

• 16?bit MSP430 core ?? provides compact instruction set and efficient integer math for control tasks.
• Integrated FRAM memory ?? enables faster writes and far higher endurance than flash, reducing maintenance needs.
• Low operating voltage (1.8?C3.6 V) ?? suits single?cell lithium and common industrial rails for design flexibility.
• Small 20?pin TSSOP package ?? saves board area compared with larger MCU packages while retaining multiple I/O lines.

Typical Applications

• Battery?powered sensor nodes that require frequent nonvolatile logging and low sleep current for multi?year operation.
• Smart metering endpoints that need reliable, high?endurance data storage for billing and event records in constrained space.
• Industrial control panels where deterministic 16?bit processing and fast nonvolatile updates reduce firmware write cycles and downtime.
• Portable instruments requiring a small footprint, wide input voltage range, and nonvolatile parameter retention after power loss.

MSP430FR2311IPW20R Advantages vs Typical Alternatives

The device combines FRAM nonvolatile memory with a 16?bit MSP430 core to deliver faster write speeds and far greater write endurance than conventional flash?based microcontrollers. At 4 KB FRAM and 256 B RAM in a 20?pin TSSOP, it offers a smaller, lower?power alternative to larger flash MCUs. The 1.8?C3.6 V range and ?40 ??C to +85 ??C rating make it more adaptable to battery and industrial rails without extra power management.
