Product details
Overview
MSP430F2272IDAR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash memory, 1KB RAM, a 10-bit 200-ksps ADC with internal reference and data transfer controller, dual 16-bit timers (Timer_A3 and Timer_B3), and a Universal Serial Communication Interface supporting UART/LIN, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring analog signal capture, digital processing, and low-latency wireless front-end interfacing.
For engineers reviewing the MSP430F2272IDAR datasheet, MSP430F2272IDAR pinout, MSP430F2272IDAR application, or MSP430F2272IDAR equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases in sensor nodes and RF front ends, and two validated alternative options for design continuity.
Technical Context
The MSP430F2272IDAR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock system integrates a digitally controlled oscillator (DCO) calibrated to ±1% across four frequencies up to 16 MHz, plus support for 32-kHz crystal, HF crystal (≤16 MHz), resonator, or external digital clock sources.
It features two independent 16-bit timers-Timer_A3 with three capture/compare registers and Timer_B3 with three capture/compare registers plus shadow registers-and a USCI module with dual independent channels: USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C). Unlike the MSP430F22x4 series, the MSP430F2272IDAR belongs to the MSP430F22x2 family and does not include operational amplifiers.

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 |
|---|---|---|---|
| MSP430F2252IDAR | 16KB+256B flash, 512B RAM, identical peripheral set and pinout (38-pin TSSOP) | Lower memory capacity suits simpler sensor firmware or cost-sensitive designs with fixed feature sets | Select when application firmware fits within 16KB flash and requires no additional RAM headroom |
| MSP430F2274IDAR | Same 32KB+256B flash and 1KB RAM, but includes two operational amplifiers (OA0/OA1) and additional analog I/O | Required for designs needing on-chip signal conditioning (e.g., sensor front-end amplification or filtering) | Choose only if op-amp functionality is explicitly needed; otherwise, MSP430F2272IDAR offers identical core performance at lower cost |
Compared with MSP430F2252IDAR, the MSP430F2272IDAR provides double flash and double RAM for complex firmware or future-proofing; compared with MSP430F2274IDAR, it omits op-amps to reduce cost and power in purely digital-sensor applications.

FAQ
What is the maximum operating frequency of the MSP430F2272IDAR?
The MSP430F2272IDAR supports a maximum system clock (MCLK) frequency of 16 MHz, achieved via its internally calibrated digitally controlled oscillator (DCO) or external HF crystal. The DCO is factory-calibrated to ±1% accuracy at four frequencies, enabling reliable high-speed operation without external components.
Does the MSP430F2272IDAR include operational amplifiers?
No, the MSP430F2272IDAR does not include operational amplifiers. It belongs to the MSP430F22x2 series, which lacks the two integrated op-amps found in the MSP430F22x4 series (e.g., MSP430F2274IDAR). This distinction is confirmed in the device family documentation and functional block diagrams.
What debug interface does the MSP430F2272IDAR support?
The MSP430F2272IDAR supports Spy-Bi-Wire (SBW), a 2-wire debug interface using pins TEST/SBWTCK (Pin 1) and RST/NMI/SBWTDIO (Pin 6). It does not require full JTAG; SBW enables programming, breakpoint debugging, and flash security management through TI's MSP-FET430UIF and compatible tools.
Is the MSP430F2272IDAR pin-compatible with other MSP430F22x2 devices in the DA package?
Yes, the MSP430F2272IDAR is fully pin-compatible with other MSP430F22x2 variants in the 38-pin TSSOP (DA) package-including MSP430F2232IDAR and MSP430F2252IDAR-sharing identical pin functions, electrical characteristics, and footprint. Firmware and PCB layouts are interchangeable within the F22x2 family.
What are the key low-power modes supported by the MSP430F2272IDAR?
The MSP430F2272IDAR supports six operating modes: Active Mode (AM), Low-Power Mode 0–3 (LPM0–LPM3), and LPM4. In LPM4, only RAM and registers retain state while all clocks stop, drawing just 0.1 µA. Wake-up from any LPM occurs in under 1 µs via interrupt, enabling aggressive power gating in sensor applications.
