Texas Instruments MSP430F2272TRHAT

Overview

MSP430F2272TRHAT 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. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.

For engineers reviewing the MSP430F2272TRHAT datasheet, MSP430F2272TRHAT pinout, MSP430F2272TRHAT application, or MSP430F2272TRHAT equivalent, key selection criteria include its 40-pin QFN (RHA) package, -40°C to 105°C temperature grade, integrated brownout detector, sub-1-µs wake-up from LPM4, and Spy-Bi-Wire debug interface compatibility.

Technical Context

The MSP430F2272TRHAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its clock system includes a digitally controlled oscillator (DCO), calibrated LF/RF oscillators, and support for external crystals up to 16 MHz - all configurable via the Basic Clock Module.

Peripherals are memory-mapped and accessible via standard instructions. The device supports five low-power modes (LPM0–LPM4), with LPM4 drawing only 0.1 µA (RAM retention), and features an Embedded Emulation Module (EEM) for on-chip debugging using Spy-Bi-Wire or JTAG.

FAQ

What is the operating temperature range of the MSP430F2272TRHAT?

The MSP430F2272TRHAT is rated for operation from –40°C to +105°C. This extended industrial temperature range ensures reliable performance in harsh environments such as outdoor sensor enclosures, motor control cabinets, and automotive under-hood applications where ambient temperatures exceed standard commercial limits.

Does the MSP430F2272TRHAT include an integrated analog comparator?

No, the MSP430F2272TRHAT does not include an integrated analog comparator. It features a 10-bit ADC with internal reference and autoscan but lacks dedicated comparator hardware. For comparator functionality, external discrete comparators or software-based threshold detection using the ADC must be implemented.

Can the MSP430F2272TRHAT support crystal oscillators above 1 MHz?

Yes, the MSP430F2272TRHAT supports high-frequency crystals up to 16 MHz via the XIN/XOUT pins. Its Basic Clock Module allows direct HF crystal connection, and the DCO can be calibrated against the crystal for stable timing - essential for UART baud rate accuracy and synchronous serial communication.

How many I/O pins does the MSP430F2272TRHAT provide in its RHA package?

The MSP430F2272TRHAT in the 40-pin QFN (RHA) package provides 32 general-purpose I/O pins across Ports P1–P4. All pins support interrupt capability, programmable pull-up/pull-down resistors, and multiple peripheral functions including timer capture/compare, ADC inputs, and USCI signal routing.

Is the MSP430F2272TRHAT pin-compatible with other MSP430F22x2 devices in the RHA package?

Yes, the MSP430F2272TRHAT is pin-compatible with other MSP430F22x2-series devices (e.g., MSP430F2232TRHAT, MSP430F2252TRHAT) in the 40-pin RHA package. Pin assignments, electrical characteristics, and peripheral mappings are identical - enabling hardware reuse across memory variants within the same family.
