Texas Instruments MSP430F2418TPN

Overview

MSP430F2418TPN 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), 16-bit Timer_A and Timer_B, and on-chip comparator - designed for battery-powered sensor systems and portable medical meters.

For engineers reviewing the MSP430F2418TPN datasheet, MSP430F2418TPN pinout, MSP430F2418TPN application, or MSP430F2418TPN equivalent, key selection criteria include LQFP-80 package compatibility, 1.8–3.6 V supply range, sub-1 µs wake-up from standby, 365 µA active current at 1 MHz/2.2 V, and absence of DAC12/DMA modules compared to F261x variants.

Technical Context

The MSP430F2418TPN implements a 16-bit CPU with constant generators and calibrated DCO enabling sub-1 µs wake-up from LPM3/LPM4. Its peripheral set includes two independent USCI modules supporting simultaneous UART, I²C, and SPI communication, plus a 12-bit ADC with internal reference and autoscan across eight channels.

It features dual 16-bit timers (Timer_A3 with three capture/compare registers; Timer_B7 with seven registers and shadow registers), programmable supply voltage supervisor (SVS) with adjustable threshold, and hardware multiplier for efficient signal processing - all operating within five low-power modes optimized for extended battery life in portable measurement applications.

FAQ

What is the maximum operating frequency of the MSP430F2418TPN?

The MSP430F2418TPN operates up to 16 MHz using the internal DCO or external XT2 oscillator. Its 16-bit RISC architecture delivers a 62.5-ns instruction cycle time at this frequency. The calibrated DCO supports stable operation across temperature and voltage variations, and the device maintains full functionality - including ADC, timers, and USCI modules - at all supported clock speeds within the 1.8–3.6 V supply range.

Does the MSP430F2418TPN include a DAC or DMA controller?

No, the MSP430F2418TPN does not include DAC12 or DMA modules. These peripherals are exclusive to the MSP430F261x series. The MSP430F2418TPN retains the full complement of timers (Timer_A3 and Timer_B7), ADC12, comparator, and dual USCI modules - making it functionally identical to the F261x family except for the omission of DAC and DMA. This simplifies design for applications that do not require analog output or high-bandwidth memory transfers.

What package type and pin count does the MSP430F2418TPN use?

The MSP430F2418TPN uses an 80-pin LQFP (PN) package with 12 mm × 12 mm body size and 0.5 mm lead pitch. It is pin-compatible with other MSP430F241x and MSP430F261x devices in the same PN package variant, allowing shared PCB layouts across the family. Pin functions are fully documented in TI SLAS541M Figure 7-1 and Section 7.1.

Can the MSP430F2418TPN support both I²C and UART simultaneously?

Yes, the MSP430F2418TPN supports concurrent I²C and UART communication using its two independent USCI modules: USCI_A0 or USCI_A1 can be configured for UART, while USCI_B0 or USCI_B1 can operate in I²C mode. This enables simultaneous host diagnostics (UART) and sensor bus communication (I²C) without software arbitration or time-slicing, critical for real-time embedded systems with multiple serial peripherals.

What is the purpose of the SVSOUT and SVSIN pins on the MSP430F2418TPN?

The SVSOUT (P5.7) and SVSIN (P6.7) pins implement the Supply Voltage Supervisor (SVS) function. SVSIN monitors an external voltage (e.g., from a voltage divider) against an internal threshold, while SVSOUT provides an open-drain output indicating SVS trip status. This enables customizable brownout detection for auxiliary rails or external circuitry - extending protection beyond the internal VCC monitor. Both pins are functional in the MSP430F2418TPN and documented in TI SLAS541M Sections 8.17 and 7.2.
