Texas Instruments MSP430F2617TPMR

Overview

MSP430F2617TPMR 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 - deployed in portable sensor systems and battery-powered industrial control nodes.

For engineers reviewing the MSP430F2617TPMR datasheet, MSP430F2617TPMR pinout, MSP430F2617TPMR application, or MSP430F2617TPMR equivalent, key selection criteria include LQFP-64 package compatibility, 8KB RAM capacity for real-time signal buffering, DAC12 voltage-output capability for analog actuation, wake-up time <1 µs from LPM3/LPM4, and calibrated DCO stability across –40°C to 85°C.

Technical Context

The MSP430F2617TPMR implements a 16-bit CPU with constant generators and 16-bit registers for optimized code efficiency in measurement applications. Its five low-power modes-including LPM4 (0.1 µA RAM retention) and standby mode with VLO (0.5 µA)-are coordinated by SVS/SVM circuitry and brownout detection for robust operation under variable supply conditions.

Peripherals are synchronized via a unified clock system with multiple sources: DCO (calibrated up to 16 MHz), LFXT1 (32.768 kHz crystal), HFXT1 (4–16 MHz crystal), and XT2 (4–16 MHz). The ADC12 supports internal reference (2.5 V), sample-and-hold, and 8-channel autoscan at up to 200 kSPS; DAC12 provides two independent voltage-output channels with monotonicity and ±1 LSB INL.

FAQ

What is the maximum operating frequency of the MSP430F2617TPMR's DCO?

The MSP430F2617TPMR's digitally controlled oscillator (DCO) is factory-calibrated up to 16 MHz and maintains ±3% accuracy over the full industrial temperature range (–40°C to 85°C) and supply voltage (1.8 V to 3.6 V). This enables deterministic real-time execution without external crystals in many applications, and the DCO supports dynamic frequency scaling via software-controlled modulation registers.

Does the MSP430F2617TPMR support hardware-accelerated cryptographic operations?

No, the MSP430F2617TPMR does not include dedicated cryptographic accelerators or hardware AES/SHA engines. It relies on software libraries for encryption tasks. For secure boot or TLS stack implementation, developers must allocate CPU cycles and RAM from its 8KB memory pool - making it suitable for lightweight security requirements but not high-throughput or FIPS-certifiable use cases.

Can the MSP430F2617TPMR's DAC12 outputs drive external loads directly?

The MSP430F2617TPMR's DAC12 outputs are buffered voltage sources rated for ±2 mA sink/source per channel into resistive loads. They are not designed to drive capacitive loads >100 pF or low-impedance loads (<2 kΩ) without external op-amp buffering. For sensor biasing or reference generation, direct connection is valid; for actuator control or audio output, external amplification is required.

How many I/O pins are available on the MSP430F2617TPMR in the LQFP-64 package?

The MSP430F2617TPMR in the 64-pin LQFP (PM) package provides 48 general-purpose I/O pins across Ports P1–P8, with individual direction, pull-up/down, and interrupt configuration. Pin multiplexing allows assignment to timer capture/compare, USCI functions, ADC inputs, or DAC outputs - all accessible without external logic or level shifters.

Is the MSP430F2617TPMR pin-compatible with the MSP430F2417TPMR?

Yes, the MSP430F2617TPMR and MSP430F2417TPMR share identical 64-pin LQFP (PM) packaging, pinout, and core peripheral mapping - including all USCI, timer, ADC, and GPIO assignments. The only functional differences are the absence of DAC12 and DMA modules in the MSP430F2417TPMR, making them drop-in replacements where those peripherals are unused.
