MSP430FR2311IRGYT 16-bit FRAM Microcontroller RGYT Package

MSP430FR2311IRGYT Overview

The MSP430FR2311IRGYT is an ultra?low?power, 16?bit microcontroller built on nonvolatile FRAM. It balances small memory footprint with predictable, fast nonvolatile writes and deterministic endurance. The device targets battery?sensitive designs that need more read/write cycles than traditional flash. Use it where lower active and standby currents, compact packaging and simple peripheral integration reduce system cost. Learn more at IC Manufacturer.

MSP430FR2311IRGYT Technical Specifications

MSP430FR2311IRGYT Key Features

• Single 16?bit RISC core with deterministic, compact instruction set for fast control tasks and low code size.
• Integrated FRAM nonvolatile memory that enables rapid in?system writes and higher endurance than flash, reducing system-level wear concerns.
• Low operating voltage (1.8?C3.6 V) and multiple low?power modes help extend battery life in portable and metered applications.
• Small 14?pin package suitable for tight PCB layouts, offering more integration per mm2 versus discrete MCU plus external memory solutions.

Typical Applications

• Battery?powered sensors and data loggers where nonvolatile FRAM allows frequent configuration or data writes without flash wear and with low standby current consumption.
• Portable metering and handheld instruments that require fast nonvolatile updates for calibration, counters or error logs and that benefit from a compact 14?pin footprint.
• Consumer appliances and user interface controls where a low?power MCU with small FRAM is used for settings retention and occasional firmware?driven state saves.
• Industrial monitoring nodes where deterministic write cycles, wide operating voltage range, and industrial temperature rating enhance reliability and long?term maintenance.

MSP430FR2311IRGYT Advantages vs Typical Alternatives

The FRAM?based architecture provides faster, repeated nonvolatile writes and greater endurance compared to typical flash?based MCUs. In many designs this reduces external EEPROM or flash needs and lowers BOM cost. The 16?bit core and 2 KB FRAM offer a tighter integration of control, memory and low?power operation versus similar PLC?class controllers. For battery and energy?harvested systems, the combination of sub?1.8 V operation margin, multiple low?power modes and a small 14?pin package makes it more efficient and compact than many pin?compatible flash devices.

FAQ

What memory type does it use?

It uses FRAM nonvolatile memory. FRAM provides fast write times and high endurance, which suits frequent configuration saves and data logging without the write?cycle limits of flash.

What is the operating voltage range?

The device operates across a low?voltage window of 1.8 to 3.6 volts, enabling direct connection to typical single?cell battery systems and common embedded power rails.

How much program memory is available?

Program and nonvolatile storage is provided as 2 KB of FRAM. This capacity supports compact firmware and on?chip storage for calibration and small data buffers.

What package options are there?

This part is supplied in a compact 14?pin package (IRGYT tape and reel option), designed for space?restricted PCBs and cost?sensitive assembly processes.

Is this suited for low?power designs?

Yes. The microcontroller includes multiple low?power modes and a low operating voltage range, which together enable extended battery life in portable and energy?harvesting applications.
