Product details
Overview
MSP430F2272TRHAR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash, 1KB RAM, 10-bit 200-ksps ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B3), and USCI modules supporting UART/LIN, IrDA, SPI, and I²C - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2272TRHAR datasheet, MSP430F2272TRHAR pinout, MSP430F2272TRHAR application, or MSP430F2272TRHAR equivalent, key selection criteria include its -40°C to 105°C industrial temperature grade, 40-pin QFN (RHA) package with 32 I/O pins, integrated brownout detector, sub-1µs wake-up from LPM4, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430F2272TRHAR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system supports internal DCO (calibrated to ±1% at 1–16 MHz), 32-kHz crystal, HF crystal up to 16 MHz, and external digital/resistor sources.
It integrates two independent 16-bit timers with capture/compare registers, a 10-bit ADC10 with data transfer controller (DTC), universal serial communication interfaces (USCI_A0 for UART/LIN/IrDA/SPI and USCI_B0 for SPI/I²C), and on-chip emulation via Spy-Bi-Wire - all optimized for operation across six low-power modes including LPM4 (0.1 µA RAM retention).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators; enables efficient code execution and low power per instruction. |
| Flash / RAM | 32KB + 256B flash memory with security fuse; 1KB RAM - sufficient for standalone sensor firmware with real-time signal processing. |
| ADC Resolution & Speed | 10-bit SAR ADC with 200-ksps sampling rate, internal reference, sample-and-hold, autoscan, and DTC - eliminates need for external DMA controller in data-acquisition designs. |
| Low-Power Performance | Active mode: 270 µA @ 1 MHz, 2.2 V; Standby: 0.7 µA; Off mode (RAM retention): 0.1 µA - extends coin-cell battery life to multi-year operation. |
| Operating Voltage | 1.8 V to 3.6 V supply range - compatible with single-cell Li-ion, LiFePO₄, and alkaline battery systems without regulation. |
| Temperature Range | -40°C to +105°C - qualified for industrial and automotive under-hood sensor applications requiring extended thermal stability. |
| Debug Interface | Spy-Bi-Wire (2-wire JTAG) with embedded emulation module (EEM) - enables full-speed debugging and flash programming using MSP-FET430UIF or MSP-GANG430. |
Pinout & Package
Package: 40-pin QFN (RHA), 6 mm × 6 mm, 0.5 mm pitch, exposed thermal pad (connected to DVSS). Pinout validated per TI SLAS504G Rev. August 2012, Table 4 (MSP430F22x4 terminal functions), applicable to MSP430F2272TRHAR as F2272 variant in RHA package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI/SBWTDIO (Pin 5) | Reset / NMI input / Spy-Bi-Wire data I/O | Single-pin reset and debug interface; enables secure programming and low-pin-count in-system debugging. |
| TEST/SBWTCK (Pin 1) | Spy-Bi-Wire test clock input | Required for programming and boundary-scan testing; must be driven externally during flash load or debug session. |
| P1.0/TACLK/ADC10CLK (Pin 29) | Timer_A clock input / ADC conversion clock | Allows synchronous sampling triggered by timer events; supports precise timing-critical analog acquisition. |
| P2.0/ACLK/A0/OA0I0 (Pin 6) | ACLK output / ADC channel A0 / Op-Amp OA0 input | Shared pin enables low-jitter clock distribution and direct sensor connection to both ADC and op-amp front-end. |
| P3.4/UCA0TXD/UCA0SIMO (Pin 23) | USCI_A0 transmit / SPI master-out | Configurable for UART-based host communication or SPI-driven peripheral control (e.g., display, EEPROM). |
| P4.6/TBOUTH/A15/OA1I3 (Pin 21) | Timer_B output high-Z / ADC A15 / OA1 input | Enables simultaneous use of timer-controlled PWM, analog monitoring, and op-amp signal conditioning on one pin. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| MSP430F2274TRHAR | Same package and pinout; adds two operational amplifiers (OA0/OA1) not present in MSP430F2272TRHAR. | Required when analog signal conditioning (e.g., sensor front-end amplification) is needed on-chip. | Select MSP430F2274TRHAR only if op-amp functionality is required; otherwise, MSP430F2272TRHAR offers identical core peripherals at lower cost. |
| MSP430FR2633IRHBT | Fram-based (not flash); 15KB FRAM + 2KB RAM; capacitive touch IO; no integrated op-amps; operates down to 1.8 V but lacks 105°C rating. | Better for touch-enabled HMI or frequent write-intensive logging; unsuitable for extended-temperature industrial deployments. | Choose MSP430FR2633IRHBT for touch-sensing or high-endurance data logging; MSP430F2272TRHAR remains preferred for wide-temp analog sensor control. |
Compared with MSP430F2274TRHAR, the MSP430F2272TRHAR omits op-amps but retains identical flash/RAM, timers, ADC, and USCI - making it optimal for cost-sensitive, non-analog-conditioning applications. Versus MSP430FR2633IRHBT, it trades FRAM endurance for guaranteed 105°C operation and analog integration, better fitting harsh-environment sensor nodes.

FAQ
What is the maximum operating frequency of the MSP430F2272TRHAR?
The MSP430F2272TRHAR supports a maximum system clock (MCLK) of 16 MHz, achievable via internal DCO (calibrated to ±1%), external HF crystal, or resonator. Its 16-bit RISC architecture delivers 62.5-ns instruction cycle time at 16 MHz, enabling real-time processing in sensor fusion and control loops without compromising power efficiency.
Does the MSP430F2272TRHAR include operational amplifiers?
No, the MSP430F2272TRHAR does not include operational amplifiers. Operational amplifiers are exclusive to the MSP430F22x4 series (e.g., MSP430F2274TRHAR). The MSP430F2272TRHAR belongs to the F22x2 series and provides identical flash, RAM, timers, ADC, and USCI peripherals but omits the two integrated op-amps found in the x4 variants.
What debug interface does the MSP430F2272TRHAR support?
The MSP430F2272TRHAR supports Spy-Bi-Wire (SBW), a 2-wire variant of JTAG, using pins RST/NMI/SBWTDIO (Pin 5) and TEST/SBWTCK (Pin 1). This interface enables full-speed debugging, flash programming, and boundary-scan testing with tools like the MSP-FET430UIF, requiring minimal PCB footprint versus 4-wire JTAG.
Is the MSP430F2272TRHAR qualified for automotive applications?
The MSP430F2272TRHAR is rated for -40°C to +105°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. It is suitable for under-hood industrial sensors and auxiliary automotive subsystems where full automotive qualification is not mandated, but not for safety-critical powertrain or ADAS applications requiring AEC certification.
How many ADC channels does the MSP430F2272TRHAR support?
The MSP430F2272TRHAR features a 10-bit ADC10 module with 12 external analog input channels (A0–A7, A12–A15) and internal references (VREF+, VREF−, temperature sensor). Its autoscan mode allows sequential conversion of up to 16 values without CPU intervention, and the Data Transfer Controller (DTC) automatically stores results in RAM.
