MSP430FR2310 — Datasheet Summary, Specs & Alternatives

01 — Overview

This TI datasheet covers the MSP430FR2310 and MSP430FR2311 mixed-signal microcontrollers. It serves as a comprehensive technical reference for designers needing low-power sensing solutions with embedded nonvolatile FRAM memory. Key parameters include a supply voltage of 1.8V to 3.6V, an active mode current of 126 µA/MHz at 3V, and a shutdown current of 32nA. The devices feature a configurable transimpedance amplifier (TIA), an integrated 6-bit DAC, and support up to 16MHz operation. Available in 16 or 20-pin TSSOP and VQFN packages, they are optimized for applications like smoke detectors and portable health monitors.
