Product details
Overview
MSP430F2616TPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 92KB+256B flash, 4KB 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.
For engineers reviewing the MSP430F2616TPNR datasheet, MSP430F2616TPNR pinout, MSP430F2616TPNR application, or MSP430F2616TPNR equivalent, key selection criteria include its 48 GPIO count, LQFP-64 package, integrated DAC/ADC co-processing capability, sub-1 µs wake-up from LPM3/LPM4, and support for simultaneous analog output generation and high-speed serial communication in compact embedded systems.
Technical Context
The MSP430F2616TPNR implements a 16-bit CPU with constant generators and a calibrated DCO enabling sub-1 µs wake-up from low-power modes. Its peripheral set includes synchronized dual 12-bit DACs (DAC0/DAC1) mapped to P6.6/P6.7 in PM package, and a 12-bit ADC12 with internal reference and sample-and-hold supporting up to 8 channels.
It integrates four USCI modules: USCI_A0/A1 support UART (with auto-baud detection), IrDA, and SPI; USCI_B0/B1 support I²C and SPI. The three-channel DMA controller enables autonomous data movement between peripherals and memory without CPU intervention, critical for deterministic real-time sampling and control loops.

FAQ
What is the maximum operating frequency of the MSP430F2616TPNR?
The MSP430F2616TPNR supports a maximum CPU clock frequency of 16 MHz using the internal DCO oscillator. This is confirmed in Section 8.19 of the datasheet, which specifies fDCO,max = 16 MHz under recommended operating conditions (VCC = 1.8 V to 3.6 V, TA = –40°C to 85°C). External crystal oscillators (LFXT1, XT2) can also be used, but the DCO provides the highest guaranteed speed without external components.
Does the MSP430F2616TPNR support hardware UART autobaud detection?
Yes, the MSP430F2616TPNR supports hardware UART autobaud detection through its USCI_A modules. As stated in the Features section, "Enhanced UART supporting automatic baud-rate detection" is explicitly listed. This capability is implemented in USCI_A0 and USCI_A1, allowing the MSP430F2616TPNR to automatically determine incoming bit rate during initialization - simplifying interoperability with variable-speed hosts.
How many general-purpose I/O pins does the MSP430F2616TPNR provide in its LQFP-64 package?
The MSP430F2616TPNR provides 48 general-purpose I/O pins in the LQFP-64 (PM) package. This is confirmed in Table 6-1 (Device Comparison) and verified in Figures 7-2 and 7-4, which show functional pin assignments for the 64-pin variant. Pins designated as DVCC, DVSS, AVCC, AVSS, XIN/XOUT, XT2IN/XT2OUT, JTAG, and reset are excluded from the GPIO count.
Is the MSP430F2616TPNR pin-compatible with other members of the MSP430F261x family?
Yes, the MSP430F2616TPNR is pin-compatible with MSP430F2617TPMR, MSP430F2618TPNR, and MSP430F2619TPNR in the same LQFP-64 (PM) package. Table 6-1 confirms identical I/O count (48), package type (PM 64), and peripheral configuration across all F261x variants. Pin functions match exactly per Figure 7-4, enabling drop-in replacement for RAM or flash upgrades without PCB redesign.
What are the supported low-power modes of the MSP430F2616TPNR and their typical current consumption?
The MSP430F2616TPNR supports five low-power modes (LPM0–LPM4). Key values: Active mode draws 365 µA at 1 MHz/2.2 V; LPM3 (VLO active) consumes 0.5 µA; LPM4 (RAM retention only) consumes 0.1 µA. These figures are specified in the Features section and validated in Sections 8.4–8.7 of the datasheet, confirming suitability for multi-year battery operation in intermittently active systems.
