MSP430FR2633IRHBT Technical Specifications

MSP430FR2633IRHBT Key Features

• FRAM nonvolatile memory for fast, low?energy writes and high endurance compared with flash.
• 16?bit MSP430 core delivering efficient code density and predictable execution for real?time tasks.
• Low operating voltage and standby modes to extend battery life in portable and autonomous systems.
• Integrated analog and serial peripherals to reduce BOM and simplify sensor interface and connectivity.

Typical Applications

• Battery?powered sensor nodes in industrial monitoring where low standby current and frequent nonvolatile logging are required (e.g., hourly data writes and long sleep cycles).
• Portable medical instruments requiring deterministic code execution, nonvolatile parameter storage, and low power draw for multi?day battery operation.
• HMI and control panels that benefit from integrated ADC, timers, and serial interfaces to drive buttons, analog sensors, and communication buses with fewer external components.
• Smart metering endpoints needing reliable nonvolatile event logging, secure power?down handling, and compact package options for constrained PCBs.

MSP430FR2633IRHBT Advantages vs Typical Alternatives

The device blends FRAM nonvolatile memory with a 16?bit MSP430 core to provide faster nonvolatile writes and higher write endurance than typical flash?based MCUs. At similar clock rates, it yields lower active and standby energy per operation, which matters in battery?sensitive designs. Integration of ADC, timers, and eUSCI serial modules reduces the need for external parts, saving board area and cost compared with solutions that require separate memory or bus interface ICs.

FAQ

What is FRAM and why use it?

FRAM is ferroelectric RAM that combines nonvolatile storage with high write endurance and low write energy. It enables fast, frequent nonvolatile updates without the erase cycles of flash, improving reliability for logging and configuration storage.

What supply voltage is supported?

The device operates across a wide low?voltage range from 1.8 V to 3.6 V, making it appropriate for single?cell lithium and many battery chemistries in low?power systems.

Which serial protocols are available?

On?chip eUSCI modules support common serial protocols including UART, SPI, and I2C. These interfaces allow direct connection to sensors, memory, and external transceivers without additional bridge ICs.

How much on?chip RAM and FRAM are provided?

This part integrates 16 KB of FRAM for nonvolatile code/data storage and 2 KB of SRAM for run?time variables and stack, supporting moderate embedded application complexity without external RAM.

What temperature range is supported?

The device is specified for industrial operation from ?40 ??C up to +85 ??C, suitable for a wide range of industrial and commercial environments.
