Overview

MSP430F2254TRHAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16 KB + 256 B Flash, 512 B RAM, two operational amplifiers, a 10-bit 200-ksps ADC with integrated reference and DTC, dual 16-bit timers (Timer_A3 and Timer_B3), USCI_A0/USCI_B0 serial interfaces (UART/LIN/IrDA/SPI/I²C), and 32 I/O pins - deployed in sensor signal acquisition, battery-powered measurement, and RF front-end control.

For engineers reviewing the MSP430F2254TRHAT datasheet, MSP430F2254TRHAT pinout, MSP430F2254TRHAT application, or MSP430F2254TRHAT equivalent, key selection criteria include its -40°C to 105°C industrial temperature grade, QFN-40 (RHA) package, dual op-amp support, brownout detector, and sub-1 µs wake-up from LPM4 - critical for energy-constrained embedded sensing systems.

Technical Context

The MSP430F2254TRHAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its 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.

It features two independent operational amplifiers (OA0 and OA1) with configurable inputs/outputs across multiple pins (e.g., P2.0/OA0I0, P2.1/OA0O, P4.3/OA0O, P4.4/OA1O), and a 10-bit ADC10 with 12 analog input channels (A0–A7, A12–A15), internal reference, sample-and-hold, autoscan, and data transfer controller - all operating under five low-power modes including LPM4 with 0.1 µA off-mode current.

FAQ

What is the operating temperature range of the MSP430F2254TRHAT?

The MSP430F2254TRHAT is rated for industrial operation from -40°C to +105°C. This extended temperature range ensures reliable performance in harsh environments such as outdoor sensor deployments, motor control enclosures, and industrial automation equipment where ambient temperatures exceed standard commercial limits. The device maintains specified timing, ADC accuracy, and op-amp performance across this full range.

Does the MSP430F2254TRHAT include integrated operational amplifiers?

Yes, the MSP430F2254TRHAT includes two fully functional operational amplifiers (OA0 and OA1) as part of its MSP430F22x4 series specification. These op amps support rail-to-rail input/output, configurable gain, and multiple pin assignments (e.g., P2.0/OA0I0, P2.1/OA0O, P4.3/OA0O, P4.4/OA1O). They are absent in the MSP430F22x2 variants, confirming their presence specifically in the MSP430F2254TRHAT.

What package type and pin count does the MSP430F2254TRHAT use?

The MSP430F2254TRHAT uses a 40-pin QFN package (RHA), measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed thermal pad. This package is confirmed in Table 1 of the SLAS504G datasheet and matches the "TRHAT" suffix, where "T" denotes temperature grade (-40°C to 105°C), "RHA" specifies the QFN-40 variant, and "T" indicates tape-and-reel packaging.

How much Flash and RAM memory does the MSP430F2254TRHAT have?

The MSP430F2254TRHAT contains 16 KB of main Flash memory plus 256 B of information Flash memory, and 512 B of RAM. These values are explicitly listed in the "Family Members Include" section of the SLAS504G datasheet under the MSP430F2254 entry, and are consistent across all package variants (YFF, DA, RHA) of this part number.

What low-power modes does the MSP430F2254TRHAT support, and what is its lowest current draw?

The MSP430F2254TRHAT supports six operating modes: Active Mode (AM) and five low-power modes (LPM0–LPM4). Its lowest current draw is 0.1 µA in Off mode (LPM4) with RAM retention, as specified in the "Ultra-Low Power Consumption" feature list. Wake-up from LPM4 occurs in less than 1 µs via interrupt, enabling rapid response while maximizing energy efficiency.
