Texas Instruments MSP430F2617TPN

Overview

MSP430F2617TPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 92KB+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. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable medical devices requiring sub-1µs wake-up and precise analog signal generation.

For engineers reviewing the MSP430F2617TPN datasheet, MSP430F2617TPN pinout, MSP430F2617TPN application, or MSP430F2617TPN equivalent, key selection criteria include its 8KB RAM capacity, dual voltage-output DACs, integrated DMA for autonomous peripheral data movement, LQFP-64 package compatibility, and support for simultaneous high-resolution ADC sampling and real-time waveform synthesis in compact embedded systems.

Technical Context

The MSP430F2617TPN implements a 16-bit CPU with constant generators and a calibrated DCO enabling sub-1 µs wake-up from LPM4. Its architecture integrates independent clock domains (ACLK, SMCLK, MCLK) and supports five low-power modes optimized for intermittent sensing and long-term battery operation.

Peripherals are tightly coupled via three DMA channels that offload CPU during ADC conversions, DAC updates, and USCI data transfers. The dual 12-bit DACs share reference inputs and support synchronized output for differential signal generation, while the 12-bit ADC includes internal reference, sample-and-hold, and 8-channel autoscan-enabling continuous sensor monitoring without CPU intervention.

FAQ

What is the maximum ADC sampling rate supported by the MSP430F2617TPN?

The MSP430F2617TPN supports a maximum ADC conversion clock (ADC12CLK) of 7 MHz, enabling up to 200 kSPS in single-channel mode. With autoscan across 8 channels, effective throughput depends on conversion time (1.86 µs minimum per sample) and channel setup overhead. The internal reference and sample-and-hold ensure consistent accuracy across this range, and the MSP430F2617TPN's DMA can autonomously store results to RAM without CPU involvement.

Does the MSP430F2617TPN support hardware UART autobaud detection?

Yes, the MSP430F2617TPN's USCI_A modules (USCI_A0 and USCI_A1) include dedicated hardware for automatic baud-rate detection in UART mode. This feature allows the MSP430F2617TPN to synchronize with unknown host transmission speeds during initial handshake - critical for field-upgradable devices and interoperability with legacy systems without preconfigured timing parameters.

What are the DAC output capabilities of the MSP430F2617TPN?

The MSP430F2617TPN integrates two independent 12-bit voltage-output DACs (DAC0 and DAC1) with programmable reference selection (internal 2.5 V or external), rail-to-rail output swing, and hardware synchronization. Each DAC supports 16 selectable output settling times (0.5–16 µs), and their outputs can be updated simultaneously via a single write - making the MSP430F2617TPN ideal for generating matched analog waveforms or precision bias voltages in sensor interfaces.

Which packages are available for the MSP430F2617TPN?

The MSP430F2617TPN is offered exclusively in the 64-pin LQFP (PM) package, measuring 10 mm × 10 mm with standard 0.5 mm pitch. This package is distinct from the 80-pin PN variant (e.g., MSP430F2617TPN) and the 113-pin nFBGA variants. The PM package supports full pin functionality including all USCI, timer, ADC, DAC, and JTAG signals, and is qualified for industrial temperature range (–40°C to 85°C).

How does the MSP430F2617TPN manage power during deep sleep modes?

The MSP430F2617TPN achieves 0.1 µA current draw in LPM4 (RAM retention only) and 0.5 µA in LPM3 (VLO active) - enabled by its segmented power domains, gated clock distribution, and ultra-low-leakage CMOS process. In these modes, the DCO is disabled, but the VLO oscillator remains active for periodic wake-up; RAM contents are preserved, and selected I/O pins retain interrupt capability. The MSP430F2617TPN wakes to full operation in under 1 µs, minimizing energy loss during state transitions.
