Texas Instruments MSP430F2272IRHAT

Overview

MSP430F2272IRHAT 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 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 MSP430F2272IRHAT datasheet, MSP430F2272IRHAT pinout, MSP430F2272IRHAT application, or MSP430F2272IRHAT equivalent, key selection criteria include its 40-pin QFN (RHA) package, -40°C to 85°C operating range, integrated brownout detector, sub-1µs wake-up from standby mode, and support for Spy-Bi-Wire debugging without external programming voltage.

Technical Context

The MSP430F2272IRHAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system includes a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz, plus support for 32-kHz crystal, HF crystal up to 16 MHz, resonator, or external digital clock source.

It integrates two independent 16-bit timers with capture/compare registers, a universal serial communication interface (USCI_A0 and USCI_B0), and a 10-bit ADC10 with data transfer controller (DTC) - all designed for deterministic real-time control in low-duty-cycle sensing applications where power budget and signal integrity are critical.

FAQ

What is the maximum operating frequency of the MSP430F2272IRHAT?

The MSP430F2272IRHAT supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal DCO calibrated to ±1% or an external HF crystal up to 16 MHz. Its 16-bit RISC architecture delivers 62.5-ns instruction cycle time at this speed, enabling real-time response in time-critical sensor fusion tasks. The MSP430F2272IRHAT maintains full functionality across its 1.8 V to 3.6 V supply range at this frequency.

Does the MSP430F2272IRHAT include an integrated analog-to-digital converter?

Yes, the MSP430F2272IRHAT integrates a 10-bit successive-approximation ADC (ADC10) with 200-ksps sampling rate, internal reference voltage generator, sample-and-hold circuitry, autoscan mode across up to 12 analog inputs, and a data transfer controller (DTC) for automatic result movement to memory without CPU involvement - eliminating polling overhead in continuous acquisition applications.

What debug interface does the MSP430F2272IRHAT support?

The MSP430F2272IRHAT supports Spy-Bi-Wire (SBW), a two-wire JTAG-compatible interface using TEST/SBWTCK and RST/NMI/SBWTDIO pins. It enables full-speed debugging, flash programming, and real-time trace without requiring external programming voltage - simplifying production programming and field firmware updates. No additional debug probe voltage translation is needed for standard 3.3 V operation.

Is the MSP430F2272IRHAT pin-compatible with other devices in the MSP430F22x2 family?

Yes, the MSP430F2272IRHAT shares identical pinout and package (40-pin QFN, RHA) with all other MSP430F22x2 variants including MSP430F2232IRHAT and MSP430F2252IRHAT. This allows hardware reuse across different memory configurations - for example, upgrading from 8KB to 32KB flash without PCB redesign - provided software accommodates memory map differences and peripheral enable states.

What low-power modes are available on the MSP430F2272IRHAT?

The MSP430F2272IRHAT offers six operating modes: Active Mode (AM) and five low-power modes (LPM0–LPM4). LPM4 disables all clocks including ACLK and draws only 0.1 µA with RAM retention, while LPM3 retains ACLK for RTC operation at 0.2 µA. Wake-up from any LPM to AM occurs in under 1 µs via DCO stabilization - critical for duty-cycled sensor wake-ups in energy-constrained deployments.
