Texas Instruments MSP430F2618TPNR

Overview

MSP430F2618TPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 116KB+256B flash, 8KB RAM, dual 12-bit DACs, 12-bit ADC, three-channel DMA, four USCI modules (UART/IrDA/SPI/I²C), and two 16-bit timers (Timer_A3 and Timer_B7). It operates from 1.8 V to 3.6 V and supports wake-up from standby in <1 µs - used in portable medical imaging systems requiring low-noise analog signal generation and precise timing control.

For engineers reviewing the MSP430F2618TPNR datasheet, MSP430F2618TPNR pinout, MSP430F2618TPNR application, or MSP430F2618TPNR equivalent, key selection criteria include its 80-pin LQFP package, integrated DAC12/DMA support (distinguishing it from F241x series), calibrated DCO for fast wake-up, and nonmagnetic packaging option for MRI-adjacent sensor front-ends.

Technical Context

The MSP430F2618TPNR implements a 16-bit CPU with constant generators and hardware multiplier for optimized code efficiency in battery-constrained measurement applications. Its clock system integrates DCO, LFXT1 (crystal), XT2, and VLO oscillators, enabling flexible low-power mode transitions and sub-µs active-mode recovery.

Peripherals include ADC12 with internal reference and autoscan, dual DAC12 channels with voltage output and synchronization, and four USCI modules supporting simultaneous UART (with auto-baud detection), IrDA, SPI, and I²C - all accessible via configurable GPIO on up to 48 pins.

Key Specifications

Pinout & Package

The MSP430F2618TPNR is packaged in an 80-pin LQFP (PN) with 12 mm × 12 mm body size and standard 0.5 mm pitch. Pin functions are fully defined per TI SLAS541M Rev M, including dedicated DAC outputs (P6.5/DAC1, P6.6/DAC0, P6.7/DAC1), analog references (VREF+, VeREF+, VREF−), and dual crystal interfaces (XIN/XOUT, XT2IN/XT2OUT).

FAQ

What is the package type and pin count of the MSP430F2618TPNR?

The MSP430F2618TPNR uses an 80-pin LQFP (PN) package with 12 mm × 12 mm body size and 0.5 mm lead pitch. This package supports all 48 I/O pins, dual crystal interfaces, analog references, and dedicated DAC outputs as specified in TI's SLAS541M datasheet. It is distinct from the 64-pin PM variant and provides full peripheral access including P7/P8 GPIO banks.

Does the MSP430F2618TPNR include DAC and DMA functionality?

Yes, the MSP430F2618TPNR includes both dual 12-bit DACs (DAC12) and a three-channel DMA controller - confirmed in the device comparison table and functional block diagrams of SLAS541M. These features are exclusive to the F261x series and absent in the F241x family, enabling synchronized analog output and zero-CPU peripheral data transfers.

What are the key low-power consumption figures for the MSP430F2618TPNR?

The MSP430F2618TPNR achieves 365 µA active current at 1 MHz/2.2 V, 0.5 µA standby (VLO mode), and 0.1 µA off mode with RAM retention. These values are measured under recommended operating conditions and reflect its optimization for battery-operated equipment where duty-cycled operation dominates system energy budget.

Can the MSP430F2618TPNR operate without an external crystal?

Yes, the MSP430F2618TPNR can operate using its internal calibrated DCO oscillator alone - supporting full functionality including ADC, DAC, and USCI modules. External crystals (LFXT1 or XT2) are optional for higher frequency stability or precision timing; the DCO enables sub-1 µs wake-up from LPM3/LPM4 without crystal start-up delay.

Is the MSP430F2618TPNR suitable for medical imaging applications?

Yes, the MSP430F2618TPNR is explicitly cited in TI documentation for medical imaging applications. Its 80-pin LQFP package is offered in a nonmagnetic variant, and its dual synchronized DAC12 outputs, low-noise ADC12, and ultra-low standby current make it appropriate for MRI-adjacent ultrasound probes and portable X-ray sensor interfaces.
