What are the key features of MSP430FR4133?
- 16-bit MSP430 RISC CPU operating at up to 8 MHz for efficient low-power computation
- 16 KB FRAM program memory with near-infinite write endurance and low-voltage operation down to 1.8 V
- Integrated LCD driver supporting up to 160 segments for direct display interfacing without external drivers
- Ultra-low active current as low as 100 µA/MHz enabling long battery life in portable applications
- 32 general-purpose I/O pins with flexible interrupt capability for responsive event-driven firmware
- 2 KB SRAM and 16 KB FRAM providing ample data and code storage for complex sensor applications
What is MSP430FR4133 used for?
The MSP430FR4133 is optimized for ultra-low-power smart meter, medical wearable, and industrial sensor node designs that require an integrated LCD driver and high-endurance non-volatile memory. Its FRAM technology enables rapid data logging and frequent calibration writes without wear-out, making it well-suited for electricity meters, water meters, and portable diagnostic devices. The 1.8 V to 3.6 V supply range and sub-microampere standby current allow multi-year operation from a pair of AA batteries in remote sensing and asset tracking applications.

Frequently Asked Questions
How many LCD segments can the MSP430FR4133 drive directly, and what display types does this support?
The MSP430FR4133 integrates an LCD driver capable of directly driving up to 160 segments, supporting segmented LCD panels commonly used in utility meters, medical devices, and handheld instruments — eliminating the need for an external LCD controller IC and reducing BOM cost and board complexity.
What makes FRAM in the MSP430FR4133 advantageous over Flash memory for data logging applications?
FRAM offers near-infinite write endurance — far exceeding the typical 10,000 to 100,000 write cycles of Flash — along with write speeds up to 125 ns per word at 3.3 V. For data-logging applications that update configuration or measurement values thousands of times daily, this means the MSP430FR4133's 16 KB FRAM will not wear out over a multi-year product lifetime.
What is the active current consumption of the MSP430FR4133, and how does it affect battery life in a smart meter application?
In active mode, the MSP430FR4133 consumes as low as 100 µA per MHz of CPU clock. At 1 MHz operation and a 3 V supply, the current draw is approximately 100 µA, enabling a standard 1500 mAh AA-cell pair to power the device in active mode for over 15,000 hours — several years — when combined with aggressive low-power sleep modes.
Which supply voltage range does the MSP430FR4133 support, and can it run directly from a lithium coin cell?
The MSP430FR4133 operates from 1.8 V to 3.6 V, making it directly compatible with a 3 V CR2032 lithium coin cell without a voltage regulator. With LPM3 standby current below 1 µA, a single coin cell can sustain the device in sleep mode for years between periodic measurement wake-up events.
