FAQ

What memory technology does it use?

It uses FRAM (ferroelectric RAM) as its nonvolatile memory. FRAM delivers fast write cycles, high endurance, and low energy-per-write compared to flash, which benefits frequent logging and configuration updates.

Which peripherals are included?

The device integrates common embedded peripherals such as serial interfaces (UART/SPI/I2C) and analog functions. For exact counts and versions (e.g., eUSCI instances, ADC type), refer to the official product sheet.

Is it suitable for battery operation?

Yes. The MSP430 family targets ultra-low-power operation with multiple sleep modes. For precise current consumption figures in each mode, consult the datasheet to size batteries and estimate runtime accurately.

How does FRAM affect design choices?

FRAM lets you write configuration and log data frequently without flash wear concerns. It simplifies firmware update strategies and reduces energy used per write. Check the datasheet for endurance and timing characteristics to align design cycles.

Where can I get detailed specs?

Detailed numerical specifications, electrical characteristics, timing diagrams, and package drawings are available in the official product sheet. Share the datasheet text or a link and I will populate the technical table with exact numbers and package data.
