Product details
Overview
MSP430F2618TZQWR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 116KB+256B flash, 8KB RAM, dual 12-bit DACs, three-channel DMA, 12-bit ADC with autoscan, two 16-bit timers (Timer_A3 and Timer_B7), four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and on-chip comparator - deployed in portable medical imaging systems requiring sub-1µs wake-up and battery longevity.
For engineers reviewing the MSP430F2618TZQWR datasheet, MSP430F2618TZQWR pinout, MSP430F2618TZQWR application, or MSP430F2618TZQWR equivalent, key selection criteria include its MicroStar Junior™ BGA-113 package, 1.8–3.6 V operation, LPM4 current of 0.1 µA, calibrated DCO with <1 µs wake-up, and dual DAC support for analog stimulus generation in sensor front-ends.
Technical Context
The MSP430F2618TZQWR implements a 16-bit CPU with constant generators and 16-bit registers for optimized code efficiency in measurement applications. Its clock system integrates a calibrated DCO, LFXT1 (crystal), VLO, and XT2 oscillators, enabling flexible low-power mode transitions and precise timing control across temperature and voltage ranges.
Peripherals are tightly coupled via the DMA controller to minimize CPU intervention: ADC12 triggers DAC12 updates, USCI modules support simultaneous asynchronous/synchronous communication, and Timer_B7's shadow registers enable glitch-free PWM output synchronization - critical for closed-loop analog signal conditioning in handheld meters.
Key Specifications

FAQ
What is the operating voltage range for the MSP430F2618TZQWR?
The MSP430F2618TZQWR operates from 1.8 V to 3.6 V. This wide supply range supports direct connection to single-cell Li-ion, Li-polymer, or alkaline battery sources without external regulation - a key enabler for compact, battery-powered medical and industrial instruments where board space and efficiency are critical. The device maintains full functionality across this range, including ADC accuracy and DAC linearity.
Does the MSP430F2618TZQWR support hardware-accelerated cryptographic functions?
No, the MSP430F2618TZQWR does not include dedicated cryptographic accelerators or hardware AES/SHA engines. It relies on software-based implementations for security tasks. For applications requiring certified encryption, consider TI's MSP430FR59xx or MSP432P4xx families. The MSP430F2618TZQWR focuses on ultra-low-power analog integration rather than security acceleration.
How many I/O pins are accessible in the MSP430F2618TZQWR MicroStar Junior™ BGA package?
The MSP430F2618TZQWR provides 48 general-purpose I/O pins in its 113-ball MicroStar Junior™ BGA package. These are distributed across Ports P1–P8, with specific pins assigned to peripheral functions (e.g., USCI, ADC, DAC). Pin multiplexing is managed via port-select registers, allowing flexible allocation between digital I/O and analog/peripheral roles per application needs.
Is the MSP430F2618TZQWR pin-compatible with other MSP430F261x variants in the same package?
Yes, the MSP430F2618TZQWR is pin-compatible with MSP430F2619TZQW, MSP430F2617TZQW, and MSP430F2616TZQW in the MicroStar Junior™ BGA-113 package. All share identical pin assignments, electrical characteristics, and mechanical footprint - enabling drop-in replacement within the F261x family for firmware-upgrade or memory-scaling scenarios without PCB revision.
What is the maximum ADC sampling rate supported by the MSP430F2618TZQWR?
The MSP430F2618TZQWR ADC12 module supports a maximum conversion clock (fADC12CLK) of 7 MHz, enabling a minimum conversion time of 1.86 µs per sample. With autoscan enabled across multiple channels, effective throughput depends on configuration, but single-channel sampling achieves up to ~537 kSPS. This rate meets requirements for high-resolution biosignal acquisition and industrial process monitoring.
