MSP430FR2632IRGER 16-bit FRAM Microcontroller, RGER Package

MSP430FR2632IRGER Overview

The MSP430FR2632IRGER is a low-power, 16?bit microcontroller built on nonvolatile FRAM memory. It combines a compact pin count, integrated analog and digital peripherals, and ultra?low active and standby currents to suit battery-powered and energy?harvesting designs. Typical designs gain faster write speeds and far higher endurance from FRAM than from flash, plus lower write energy. For sourcing and further technical resources visit IC Manufacturer.

MSP430FR2632IRGER Technical Specifications

MSP430FR2632IRGER Key Features

• Single 16?bit CPU core with deterministic execution for tight control loops and lower code size.
• FRAM memory that writes faster and uses less energy than typical flash, reducing write latency and extending device lifetime.
• Integrated 12?bit ADC and two flexible eUSCI modules to simplify mixed?signal and serial designs without external converters.
• Multiple low?power modes with rapid wake-up to save battery life in always?on or intermittent sampling applications.

Typical Applications

• Battery?powered sensors and data loggers requiring frequent nonvolatile updates and long write endurance for field data retention over millions of cycles.
• Portable medical and wearable devices that need low active current, fast wake?up, and mixed analog inputs with compact BOM and minimal external components.
• Industrial monitoring nodes and asset trackers that demand reliable operation across ?40 ??C to +85 ??C and stable serial connectivity via UART, SPI, or I2C.
• Energy?harvesting controllers and metering endpoints where FRAM??s low write energy and near?instantaneous write speed enable efficient power budgeting and robust nonvolatile storage.

MSP430FR2632IRGER Advantages vs Typical Alternatives

The device offers clear benefits compared with standard flash?based 16?bit MCUs. FRAM delivers faster writes, lower energy per write, and far higher endurance, which reduces lifetime failure risk in frequent?write systems. The integrated ADC and dual eUSCI modules cut board area and component count versus solutions that require external converters or bridges. Low?power modes plus rapid wake?up provide measurable battery?life gains in duty?cycled applications where every microamp and millisecond matters.

FAQ

What memory type does it use?

The device uses FRAM (ferroelectric RAM) as its nonvolatile memory. FRAM provides faster writes and higher endurance than flash, allowing frequent updates without accelerated wear.

Which serial interfaces are available?

Two configurable eUSCI modules support UART, SPI and I2C modes. These provide flexible, hardware?accelerated serial communication for sensors, radios, and external peripherals.

Is it suitable for battery?powered designs?

Yes. The MCU implements multiple low?power modes and fast wake?up. Combined with FRAM??s low write energy, this reduces average power consumption in intermittent sampling or always?on applications.

What analog functions are included?

On?chip analog integration includes a 12?bit ADC, enabling accurate sensor measurements without immediate need for external ADC components in many designs.

What package and temperature range are offered?

The MSP430FR2632IRGER is supplied in a 32?pin RGE package with an industrial temperature rating, supporting typical operations from ?40 ??C to +85 ??C for industrial applications.
