Product details
Overview
MSP430F2616TPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 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 systems and portable medical devices.
For engineers reviewing the MSP430F2616TPN datasheet, MSP430F2616TPN pinout, MSP430F2616TPN application, or MSP430F2616TPN equivalent, key selection criteria include its dual DAC support, integrated DMA for sensor data throughput, LQFP-64 package compatibility, and verified wake-up time under 1 µs from standby mode - critical for energy-constrained embedded control.
Technical Context
The MSP430F2616TPN implements a 16-bit CPU with constant generators and a calibrated DCO enabling sub-1-µs wake-up from LPM3/LPM4. Its peripheral set includes synchronized dual 12-bit DACs (DAC0/DAC1) with voltage output, a 12-bit ADC12 supporting up to 8 channels with internal reference and sample-and-hold, and Timer_B7 with shadow registers for glitch-free PWM generation.
Four USCI modules provide independent configurable serial interfaces: USCI_A0/A1 support UART, IrDA, and SPI with automatic baud-rate detection; USCI_B0/B1 support I²C and SPI. The device integrates SVS/SVM for supply monitoring, brownout reset, and JTAG-based emulation - all optimized for deterministic real-time operation in low-power sensing nodes.

FAQ
What is the maximum operating frequency of the MSP430F2616TPN CPU?
The MSP430F2616TPN features a 16-bit RISC CPU with a 62.5-ns instruction cycle time, corresponding to a maximum sustained operating frequency of 16 MHz. This is achieved using the internal digitally controlled oscillator (DCO) or external crystal sources (LFXT1 or XT2), and is fully supported across all active power modes per TI SLAS541M Section 8.19.
Does the MSP430F2616TPN support hardware-accelerated cryptographic operations?
No, the MSP430F2616TPN does not include dedicated cryptographic accelerators or hardware AES/SHA engines. Its security features are limited to programmable code protection via the security fuse and bootloader (BSL) access control. For secure boot or encrypted communication, software-based implementations or external co-processors are required.
What package options are available for the MSP430F2616TPN?
The MSP430F2616TPN is exclusively offered in the 64-pin LQFP (PM) package with 10 mm × 10 mm body size and 0.5 mm pitch. Unlike other members of the F261x family (e.g., MSP430F2616TPN is not available in 80-pin LQFP or nFBGA variants - only the PM variant carries the "TPN" suffix per TI's orderable part numbering convention.
How many USCI modules does the MSP430F2616TPN integrate, and what protocols do they support?
The MSP430F2616TPN integrates four USCI modules: USCI_A0 and USCI_A1 support UART, IrDA, and synchronous SPI; USCI_B0 and USCI_B1 support I²C and synchronous SPI. Each module operates independently, enabling concurrent use of UART for host communication and I²C for sensor interfacing without resource contention.
Is the MSP430F2616TPN pin-compatible with the MSP430F2416TPM?
Yes, the MSP430F2616TPN and MSP430F2416TPM share identical 64-pin LQFP (PM) packages and pinouts - including matching signal assignments for power, reset, JTAG, USCI, ADC, and timer functions. However, pins P6.5 and P6.6 are configured as DAC outputs on MSP430F2616TPN but retain analog input-only functionality on MSP430F2416TPM, requiring firmware validation for analog peripheral usage.
