Product details
Overview
MSP430F2418TPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 116KB+256B flash, 8KB RAM, 12-bit ADC, dual USCI_A/USCI_B modules (UART/I²C/SPI), Timer_A and Timer_B, and on-chip comparator - designed for battery-powered sensor systems and portable measurement devices operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F2418TPNR datasheet, MSP430F2418TPNR pinout, MSP430F2418TPNR application, or MSP430F2418TPNR equivalent, key selection criteria include LQFP-64 package compatibility, 8KB RAM capacity, absence of DAC12/DMA modules (vs. F261x), wake-up time <1 µs from standby, and calibrated DCO oscillator performance across temperature and voltage.
Technical Context
The MSP430F2418TPNR implements a 16-bit CPU with constant generators and five low-power modes optimized for extended battery life. Its architecture supports fast wake-up via the digitally controlled oscillator (DCO), which achieves sub-microsecond transition from LPM3/LPM4 to active mode.
It integrates two independent universal serial communication interfaces (USCI_A0/USCI_A1 for UART/LIN/IrDA/SPI; USCI_B0/USCI_B1 for I²C/SPI), a 12-bit ADC12 with internal reference and autoscan, and dual 16-bit timers (Timer_A3 with three capture/compare registers; Timer_B7 with seven registers and shadowing) - all without DAC or DMA functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables high code efficiency in resource-constrained embedded firmware. |

FAQ
What is the maximum operating frequency of the MSP430F2418TPNR?
The MSP430F2418TPNR supports a maximum system clock (MCLK) of 16 MHz using the XT2 oscillator or calibrated DCO. Its 16-bit RISC core executes instructions at 62.5 ns per cycle, enabling deterministic real-time response in time-critical firmware. The device does not require external clock multiplication; all timing paths are verified up to 16 MHz in the official datasheet.
Does the MSP430F2418TPNR include a hardware DAC?
No, the MSP430F2418TPNR does not include a DAC12 module. As confirmed in the device comparison table and functional block diagrams, DAC12 is exclusive to the MSP430F261x series. The MSP430F2418TPNR retains the full 12-bit ADC12, Timer_A, Timer_B, USCI modules, and comparator - but omits both DAC12 and DMA controllers to reduce cost and power in sensing-focused applications.
What package type and dimensions does the MSP430F2418TPNR use?
The MSP430F2418TPNR uses a 64-pin LQFP (PM) package measuring 10 mm × 10 mm with 0.5 mm lead pitch. This nonmagnetic variant is explicitly qualified for medical imaging applications per TI documentation. Pinout matches Figure 7-2 in SLAS541M, supporting drop-in compatibility with other MSP430F241x PM-package devices.
Can the MSP430F2418TPNR support I²C communication?
Yes, the MSP430F2418TPNR supports I²C communication via its two USCI_B modules (USCI_B0 and USCI_B1). Each module operates in I²C master or slave mode with programmable clock speed, automatic ACK/NACK handling, and 7-bit/10-bit addressing. I²C signals are assigned to P3.1/P3.2 (UCB0SDA/UCB0SCL) and P5.1/P5.2 (UCB1SDA/UCB1SCL) - enabling concurrent connection to multiple I²C peripherals.
Is the MSP430F2418TPNR pin-compatible with the MSP430F2618TPNR?
No, the MSP430F2418TPNR is not pin-compatible with the MSP430F2618TPNR in the same package. While both share the LQFP-64 (PM) footprint, their pin functions differ: P6.5/P6.6/P6.7 on MSP430F2618TPNR serve DAC1 output roles, whereas those pins on MSP430F2418TPNR are general-purpose analog inputs (A5/A6/A7). Direct replacement requires PCB redesign to accommodate functional differences.
