MSP430FR2155TPTR Overview
The MSP430FR2155TPTR is a low-power, 16-bit microcontroller family member that uses nonvolatile FRAM for fast, endurance-rich code and data storage. To generate a precise, spec-accurate datasheet-style description, I need the official product sheet because this output will strictly mirror documented values without inventing numbers. Once the sheet is supplied I will produce a fully validated technical summary, pinout, electrical characteristics and application guidance tuned for engineers and sourcing teams. For original manufacturer reference see IC Manufacturer.

MSP430FR2155TPTR Key Features
- FRAM nonvolatile memory ?? enables faster writes and higher endurance compared with conventional flash, reducing code- and data-update latency.
- 16?bit RISC core ?? provides compact code density and deterministic interrupt response for real-time embedded control tasks.
- Low-voltage operation ?? supports battery-friendly voltages typically used in portable and energy-constrained systems.
- Integrated peripherals ?? on-chip timers, serial interfaces and analog blocks reduce BOM count and simplify PCB routing when compared to discrete solutions.
Typical Applications
- Battery-powered sensors and portable instruments that require ultra?low power standby, frequent data logging and robust nonvolatile storage for firmware and parameters.
- Energy metering and industrial sensing nodes where frequent small writes and high endurance nonvolatile memory reduce maintenance and increase lifetime.
- Human?machine interface panels and control buttons that need deterministic response, persistent configuration storage, and minimal wake-up current.
- IoT edge nodes and wireless sensor endpoints that benefit from reduced code-update times, resilient FRAM data retention, and integrated peripheral sets to minimize BOM.
MSP430FR2155TPTR Advantages vs Typical Alternatives
The core advantage is the combination of FRAM with the MSP430 16?bit architecture, delivering faster write times and far greater write endurance than typical flash-based microcontrollers. Compared with similar-density flash MCUs, this model reduces latency for frequent nonvolatile updates and improves reliability for configuration storage. The device also emphasizes low-voltage operation and integrated peripherals, which can lower system power and parts count when compared to solutions that require external memory or discrete analog components.
