Product details
Overview
MSP430F2272IDA from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash, 1KB RAM, dual 16-bit timers (Timer_A and Timer_B), 10-bit 200-ksps ADC with internal reference and data transfer controller, USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and 32 I/O pins - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2272IDA datasheet, MSP430F2272IDA pinout, MSP430F2272IDA application, or MSP430F2272IDA equivalent, key selection criteria include active-mode current (270 µA @ 1 MHz, 2.2 V), standby-mode consumption (0.7 µA), wake-up time (<1 µs), 38-pin TSSOP package compatibility, and integrated analog peripherals including dual op amps (MSP430F2274 only - not applicable to MSP430F2272).
Technical Context
The MSP430F2272IDA 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, resonator, or external digital clock source.
It features five software-selectable low-power modes (LPM0–LPM4), brownout detection, on-chip emulation module (EEM), and Spy-Bi-Wire debug interface. The device lacks the two operational amplifiers present in the MSP430F2274 variant - confirmed by TI SLAS504G revision August 2012.

FAQ
What is the maximum operating frequency of the MSP430F2272IDA?
The MSP430F2272IDA supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) with factory calibration or an external HF crystal up to 16 MHz. This allows real-time execution of time-critical tasks while maintaining ultra-low-power operation in active mode.
Does the MSP430F2272IDA include operational amplifiers?
No, the MSP430F2272IDA does not include operational amplifiers. Operational amplifiers are exclusive to the MSP430F22x4 series (e.g., MSP430F2274IDA). The MSP430F2272IDA is part of the MSP430F22x2 family, which omits the two OA blocks but retains all other analog and digital peripherals including the 10-bit ADC and USCI modules.
What debug interface does the MSP430F2272IDA support?
The MSP430F2272IDA supports the Spy-Bi-Wire (SBW) interface using pins TEST/SBWTCK (Pin 1) and RST/NMI/SBWTDIO (Pin 6). This 2-wire debug protocol is fully compatible with TI's MSP-FET430UIF and MSP-FET430U38 programmers, enabling flash programming, breakpoint debugging, and real-time register inspection without requiring a full 4-pin JTAG header.
What is the ADC resolution and sampling rate of the MSP430F2272IDA?
The MSP430F2272IDA integrates a 10-bit successive approximation register (SAR) ADC capable of up to 200 ksamples per second (ksps). It supports 12 analog input channels, internal reference voltage, sample-and-hold, autoscan mode, and data transfer controller (DTC) - enabling autonomous multi-channel acquisition without CPU involvement.
Is the MSP430F2272IDA pin-compatible with other devices in the MSP430F22x2 family?
Yes, the MSP430F2272IDA is pin-compatible with other MSP430F22x2 variants in the same DA (38-pin TSSOP) package, including MSP430F2232IDA and MSP430F2252IDA. All share identical pin functions, electrical characteristics, and footprint - allowing hardware reuse across memory-graded versions during design scaling or cost optimization.
