It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable medical devices.

For engineers reviewing the MSP430F2616TZQWR datasheet, MSP430F2616TZQWR pinout, MSP430F2616TZQWR application, or MSP430F2616TZQWR equivalent, key selection criteria include its MicroStar Junior™ BGA-113 package, 48 I/O pins, calibrated DCO enabling <1 µs wake-up from LPM4, integrated DAC12 channels for analog output control, and dual USCI_A/USCI_B modules supporting simultaneous UART and I²C communication in compact embedded systems.

Technical Context

The MSP430F2616TZQWR implements a 16-bit CPU with constant generators and 62.5-ns instruction cycle time, paired with five low-power modes optimized for extended battery life. Its architecture integrates DMA for zero-CPU-overhead peripheral data movement between ADC12, DAC12, and memory.

It features two independent USCI modules per interface type (USCI_A0/A1 for UART/IrDA/SPI; USCI_B0/B1 for I²C/SPI), enabling concurrent serial protocols without resource contention. The DAC12 subsystem provides synchronized voltage-output dual channels with programmable reference selection (VeREF+/VREF−) and built-in buffer amplifiers.

FAQ

What is the package type and pin count of the MSP430F2616TZQWR?

The MSP430F2616TZQWR uses the MicroStar Junior™ BGA-113 package with 113 solder balls and a 7 mm × 7 mm body size. It provides 48 general-purpose I/O pins, with dedicated signals for JTAG debugging, multiple crystal oscillators (LFXT1, XT2), ADC/DAC references, and power domains (DVCC/DVSS/AVCC/AVSS). This package is RoHS-compliant and qualified for industrial temperature range (–40°C to 85°C).

Does the MSP430F2616TZQWR support simultaneous UART and I²C communication?

Yes, the MSP430F2616TZQWR supports simultaneous UART and I²C communication using its four USCI modules: USCI_A0 and USCI_A1 can be configured independently as UART, IrDA, or SPI; USCI_B0 and USCI_B1 support I²C or SPI. For example, USCI_A0 can handle UART communication with a host MCU while USCI_B1 manages an I²C sensor bus - all without CPU overhead due to DMA support.

What are the key low-power capabilities of the MSP430F2616TZQWR?

The MSP430F2616TZQWR achieves ultra-low power via five operating modes: Active mode draws 365 µA at 1 MHz/2.2 V; Standby (VLO) consumes 0.5 µA; Off mode with RAM retention uses only 0.1 µA. Wake-up from LPM4 to active mode takes less than 1 µs thanks to its calibrated DCO. These characteristics make MSP430F2616TZQWR ideal for multi-year battery operation in remote sensing and metering applications.

How does the DAC12 subsystem function in the MSP430F2616TZQWR?

The MSP430F2616TZQWR integrates two synchronized 12-bit voltage-output DACs (DAC0 and DAC1) with independent reference selection (VREF+, VREF−, or VeREF+). DAC outputs are buffered and can drive resistive loads up to 10 kΩ. Synchronization ensures simultaneous updating of both channels via a single DAC12CTL0 register write - critical for generating matched analog stimuli in calibration systems or differential actuator control.

Is the MSP430F2616TZQWR pin-compatible with other devices in the F261x family?

Yes, the MSP430F2616TZQWR is pin-compatible with all other MSP430F261x variants (e.g., MSP430F2617TZQWR, MSP430F2618TZQWR) in the same MicroStar Junior™ BGA-113 package. Differences are limited to internal resources (RAM size, flash content), not pin function mapping. This allows hardware reuse across firmware variants - for example, upgrading to 8KB RAM by swapping to MSP430F2617TZQWR without PCB changes.
