MSP430FR5869IRGZR Technical Specifications

MSP430FR5869IRGZR Key Features

• Single 16-bit MSP430 core with deterministic instruction execution, enabling predictable response times in real-time control.
• FRAM nonvolatile memory for faster writes and higher endurance compared to typical flash, which reduces latency and increases write cycles.
• Low-power modes and sub-microamp standby currents to extend battery life in portable or remote industrial systems.
• Integrated 12-bit ADC and multiple timers for accurate analog sensing and precise PWM generation without external components.

Typical Applications

• Battery-powered sensor nodes where FRAM??s faster writes and low active current extend runtime and simplify firmware logging strategies over flash-based MCUs.
• Precision motor control and small actuator systems that need deterministic 16-bit control loops, multiple timers, and PWM outputs for stable performance.
• Industrial human-machine interfaces where low standby current and quick wake-up reduce heat and power, while serial interfaces connect displays and touch controllers.
• Smart metering and energy monitoring endpoints that require nonvolatile data logging, 12-bit ADC measurements, and reliable operation across -40 ??C to +85 ??C.

MSP430FR5869IRGZR Advantages vs Typical Alternatives

The device combines FRAM with a 16-bit MSP430 core to deliver faster nonvolatile writes and far higher endurance than flash-based alternatives. It typically consumes less active and standby power versus many 8/32-bit flash MCUs, which improves battery life. Integrated 12-bit ADC and multiple serial peripherals reduce component count compared to discrete solutions. Overall, it offers a smaller system footprint, quicker nonvolatile updates, and lower long-term power consumption.

FAQ

What memory type does it use?

The device uses FRAM (ferroelectric RAM) as main nonvolatile memory. FRAM supports fast writes and much higher endurance than typical flash memories, which benefits frequent data logging and in-field updates.

What development tools are supported?

Development typically uses TI toolchains and community-supported IDEs. Standard support includes debug adapters and software tools for compiling, programming, and on-chip debugging of MSP430 microcontrollers.

Can it run from batteries?

Yes. Its low active and standby currents and a 1.8 V to 3.6 V supply range make it suitable for battery-powered devices and energy-harvesting nodes requiring long autonomous operation.

Which analog peripherals are available?

Integrated analog features include a 12-bit ADC and analog input channels for sensors. These peripherals allow direct digitization and signal conditioning without many external components.

What serial interfaces are provided?

On-chip serial interfaces include UART, SPI, and I2C-compatible modules. These interfaces provide flexible connectivity for sensors, memory, and communications in compact designs.
