FAQ

What is the maximum operating frequency of the MSP430F2618TPMR?

The MSP430F2618TPMR supports a maximum system clock (MCLK) of 16 MHz using the XT2 high-frequency crystal oscillator. Its calibrated DCO operates up to 16 MHz without external components, and the CPU executes instructions at a 62.5-ns cycle time - enabling deterministic real-time response in time-critical sensor applications. The MSP430F2618TPMR's architecture sustains this performance while maintaining ultra-low active-mode current (365 µA @ 1 MHz, 2.2 V).

Does the MSP430F2618TPMR support hardware debugging via JTAG?

Yes, the MSP430F2618TPMR includes a full IEEE 1149.1-compliant JTAG interface with TCK, TMS, TDI, and TDO pins. It supports boundary-scan testing, flash programming, and real-time debugging without requiring external voltage - all accessible through the 64-pin LQFP package. This capability is integral to development workflows using TI's MSP-FET and Code Composer Studio, and remains functional even after security fuse programming.

What analog peripherals are integrated into the MSP430F2618TPMR?

The MSP430F2618TPMR integrates a 12-bit ADC12 with 8 input channels, internal reference, sample-and-hold, and autoscan; dual 12-bit DAC12 modules with voltage output and synchronization; an 8-channel comparator (Comp_A+); and programmable supply voltage supervisor (SVS). These peripherals are fully accessible on the 64-pin LQFP package - for example, P6.5/P6.6/P6.7 serve as DAC1/DAC0 outputs and SVSIN monitor inputs.

Is the MSP430F2618TPMR available in a nonmagnetic package?

Yes, the MSP430F2618TPMR is offered in a nonmagnetic 64-pin LQFP (PM) package variant specifically qualified for medical imaging environments such as MRI-adjacent patient monitors. This version replaces ferromagnetic materials in leadframe and mold compound to prevent magnetic field distortion and RF interference - confirmed in TI's device documentation and supported by the "nonmagnetic" designation in official ordering information.

How does the MSP430F2618TPMR handle low-power mode transitions?

The MSP430F2618TPMR achieves sub-microsecond wake-up from standby mode (LPM3/LPM4) using its calibrated digitally controlled oscillator (DCO), with typical wake-up time <1 µs. It supports five low-power modes, including RAM-retention off-mode drawing only 0.1 µA. Clock gating, peripheral isolation, and automatic context preservation minimize energy per transition - making it ideal for intermittent-sampling sensor nodes where responsiveness and battery longevity are jointly constrained.
