MSP430FR69221IRGCT Key Features

• Low-power 16-bit MSP430 core for efficient control and deterministic real-time response.
• FRAM nonvolatile memory for fast writes and high endurance, which shortens write cycles and improves data-logging reliability.
• Wide operating voltage (1.8?C3.6 V) that enables battery and single-supply system designs with fewer regulators.
• Rich I/O availability in a 48-pin package for higher integration and reduced external component count.
• Multiple low-power modes to extend battery life and reduce standby energy consumption in remote or portable systems.
• Integrated analog peripherals to simplify sensor interfacing and lower system cost by replacing external ADCs or references.

Typical Applications

• Battery-powered sensor nodes for industrial monitoring, where low active and sleep currents extend operational life beyond competitors with higher consumption.
• Human-machine interface controllers that require fast nonvolatile register updates and frequent state saves without sacrificing responsiveness.
• Data loggers and metering equipment that benefit from FRAM??s high endurance for repeated writes and reliable long-term storage.
• Embedded control in portable instruments where tight power budgets and compact 48-pin packaging reduce overall system size and cost.

MSP430FR69221IRGCT Advantages vs Typical Alternatives

The device pairs a 16-bit MSP430 core with FRAM to deliver faster nonvolatile writes and higher endurance than flash-based alternatives. It operates from 1.8 V to 3.6 V, offering broader supply flexibility than many single-voltage MCUs. The 48-pin package provides more GPIO and peripheral integration compared with smaller packages, reducing external components and board area. Multiple low-power modes and sub-??A retention currents make it well suited for long-life battery and industrial applications where energy efficiency and data integrity matter.

FAQ

What is the nonvolatile memory type?

This device uses FRAM as its nonvolatile memory. FRAM provides fast write speeds, high endurance for frequent writes, and low energy per write compared with traditional flash memory.

Which supply voltages are supported?

The MCU supports an operating range from 1.8 volts up to 3.6 volts. This wide range allows direct use with common battery chemistries and single-supply designs without additional regulators.

What package should I expect?

The product is supplied in a 48-pin QFN-style package (RGC code). This compact 48-pin footprint balances I/O count with small PCB area for space-constrained industrial designs.

How does FRAM improve reliability?

FRAM increases endurance and write-cycle durability. It tolerates many more write cycles than flash, reducing risk of memory wear in frequent-logging or configuration-update use cases.

Is the device suitable for low-temperature operation?

Yes. The operating temperature range covers industrial-grade use from -40 ??C to +85 ??C, which suits outdoor and factory-floor environments requiring robust temperature tolerance.
