Product details
Overview
MSP430F2274TDA from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash, 1KB RAM, dual operational amplifiers, 10-bit 200-ksps ADC with integrated reference and DTC, two 16-bit timers (Timer_A3 and Timer_B3), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and 32 I/O pins - deployed in sensor signal acquisition, battery-powered metering, and RF front-end control.
For engineers reviewing the MSP430F2274TDA datasheet, MSP430F2274TDA pinout, MSP430F2274TDA application, or MSP430F2274TDA equivalent, this page delivers verified functional architecture, DA-package terminal mapping, low-power mode timing, op-amp configuration support, and direct alternative part comparisons for embedded design validation and BOM optimization.
Technical Context
The MSP430F2274TDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its clock system integrates DCO (calibrated to ±1% at 1–16 MHz), ACLK (LF crystal or VLO), SMCLK, and MCLK - all configurable via the Basic Clock Module for dynamic power/performance trade-offs.
It supports five software-selectable low-power modes (LPM0–LPM4), with wake-up from LPM4 in <1 µs via interrupt. The dual op-amps (OA0/OA1) are fully configurable as PGA, comparator, or filter stages, with dedicated analog inputs (e.g., OA0I0–OA0I3, OA1I0–OA1I3) and outputs routed to P2.x/P3.x/P4.x pins per DA-package pinout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and 62.5-ns instruction cycle time - enables deterministic real-time execution and compact firmware footprint. |
| Memory | 32KB + 256B flash / 1KB RAM - sufficient for complex sensor fusion algorithms and bootloader + application partitioning. |
| ADC | 10-bit, 200-ksps SAR ADC with 12-channel autoscan, internal reference, sample-and-hold, and Data Transfer Controller - eliminates host CPU overhead during multi-channel acquisition. |
| Timers | Timer_A3 (3 capture/compare registers) + Timer_B3 (3 capture/compare registers with shadow registers) - supports PWM generation, input capture, and precise time-stamping of analog events. |
| Communication | USCI_A0 (UART/LIN/IrDA/SPI) + USCI_B0 (SPI/I²C) - enables simultaneous wired sensor bus (I²C) and host interface (LIN/UART) without external transceivers. |
| Op-Amps | Two rail-to-rail operational amplifiers (OA0, OA1) with programmable gain and multiple input/output routing options - usable as PGA, active filters, or precision comparators in analog front ends. |

Pinout & Package
Package: 38-pin Thin Shrink Small-Outline Package (TSSOP), suffix "DA", JEDEC MO-153 compliant, 9.7 mm × 4.4 mm footprint, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ADC10CLK | Timer_A clock input / ADC conversion clock | Enables synchronous sampling triggered by timer overflow; supports precise timing-critical analog acquisition. |
| P2.0/ACLK/A0/OA0I0 | ACLK output / ADC channel A0 / OA0 non-inverting input | Shared analog/digital resource allows OA0 to condition A0 signal before digitization - reduces external component count. |
| P2.3/TA1/A3/VREF−/VeREF−/OA1I1/OA1O | ADC channel A3 / OA1 inverting input & output | Configurable as OA1 output (buffered reference) or input (differential sensing) - supports ratiometric measurement with internal VREF. |
| P4.3/TB0/A12/OA0O | Timer_B channel 0 / ADC channel A12 / OA0 output | Direct OA0 output routing to ADC input A12 enables closed-loop analog processing (e.g., auto-zeroing amplifier feedback). |
| RST/NMI/SBWTDIO | Reset / NMI input / Spy-Bi-Wire data I/O | Single-pin debug interface supports programming and in-circuit emulation without JTAG header - saves PCB space. |
| TEST/SBWTCK | Spy-Bi-Wire test clock | Enables production programming and boundary-scan testing using 2-wire interface - simplifies test fixture design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2272TDA | 16KB+256B flash, 512B RAM, no op-amps - identical DA package and peripheral set otherwise. | Lacks dual op-amps; unsuitable for analog front-end conditioning requiring PGA or active filtering. | Select when application requires only basic ADC/timer/comm functions and cost reduction is prioritized over analog integration. |
| MSP430F2254TDA | 16KB+256B flash, 512B RAM, includes dual op-amps - matches MSP430F2274TDA analog capability but halves flash/RAM capacity. | Same op-amp functionality and pin compatibility, but insufficient memory for complex firmware or large lookup tables. | Choose for simpler sensor nodes where 16KB flash suffices and dual op-amps are mandatory. |
Compared with MSP430F2272TDA and MSP430F2254TDA, the MSP430F2274TDA uniquely combines full dual-op-amp support with 32KB flash and 1KB RAM - enabling standalone analog-digital processing without external signal chain components or memory expansion.

FAQ
What is the maximum operating frequency of the MSP430F2274TDA?
The MSP430F2274TDA supports internal DCO frequencies up to 16 MHz, calibrated to ±1% across temperature and voltage. It also accepts external HF crystals up to 16 MHz or resonators for precise timing-critical applications like LIN communication or high-speed ADC sampling - all managed through the Basic Clock Module without external PLL circuitry.
Does the MSP430F2274TDA include hardware debug support?
Yes, the MSP430F2274TDA integrates an Embedded Emulation Module (EEM) and supports Spy-Bi-Wire (2-wire JTAG) via TEST/SBWTCK and RST/NMI/SBWTDIO pins. This enables full in-circuit debugging, flash programming, and real-time trace without requiring a 4-pin JTAG header - reducing PCB layout complexity and test cost.
How many analog input channels does the MSP430F2274TDA ADC support?
The MSP430F2274TDA's 10-bit ADC10 supports 12 analog input channels (A0–A7, A12–A15), with autoscan mode enabling sequential conversion of up to 16 values per trigger. Channel selection is controlled via ADC10CTL1 register, and conversions can be initiated by timer, software, or external signal - all coordinated by the integrated Data Transfer Controller (DTC).
Can the op-amps in the MSP430F2274TDA drive external loads directly?
Yes, both OA0 and OA1 in the MSP430F2274TDA are rail-to-rail output operational amplifiers capable of driving capacitive loads up to 100 pF and resistive loads down to 2 kΩ while maintaining stability. Their outputs (e.g., OA0O on P4.3, OA1O on P4.4) are directly routable to ADC inputs or external circuitry - eliminating need for external buffer stages in most sensor interface designs.
Is the MSP430F2274TDA pin-compatible with other MSP430F22x4 variants in TSSOP package?
Yes, all MSP430F22x4 devices (including MSP430F2234TDA, MSP430F2254TDA, and MSP430F2274TDA) share identical 38-pin TSSOP (DA) pinouts and electrical characteristics. Firmware and PCB layouts are interchangeable across this variant group - allowing scalable memory selection without hardware redesign.
