Product details
Overview
MSP430F2274IRHAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash, 1KB RAM, dual operational amplifiers, 10-bit 200-ksps ADC with integrated reference and DTC, two 16-bit timers (Timer_A3 and Timer_B3), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and 32 I/O pins - deployed in sensor signal acquisition, battery-powered measurement, and RF front-end control systems.
For engineers reviewing the MSP430F2274IRHAT datasheet, MSP430F2274IRHAT pinout, MSP430F2274IRHAT application, or MSP430F2274IRHAT equivalent, key selection considerations include its 40-pin QFN (RHA) package, -40°C to 85°C industrial temperature grade, dual op-amp support, 1.8–3.6 V supply range, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430F2274IRHAT 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 internal frequencies up to 16 MHz (±1%), and support for 32-kHz crystal, HF crystal (≤16 MHz), resonator, or external digital clock sources.
It supports five low-power modes (LPM0–LPM4), achieving sub-1 µs wake-up from standby (0.7 µA) and 0.1 µA off-mode (RAM retention). Peripherals include two configurable op amps (OA0/OA1) with multiple input/output configurations, 12-channel ADC10 with autoscan and data transfer controller, and dual 16-bit timers with capture/compare registers and shadow registers (Timer_B).

FAQ
What is the operating temperature range for the MSP430F2274IRHAT?
The MSP430F2274IRHAT is rated for industrial operation from –40°C to +85°C. This range is validated across all electrical specifications including flash programming, ADC linearity, op-amp offset, and timer accuracy - ensuring reliable performance in outdoor sensor enclosures, factory-floor equipment, and automotive cabin applications without additional thermal management.
Does the MSP430F2274IRHAT support in-system programming without external voltage?
Yes, the MSP430F2274IRHAT supports serial onboard programming with no external programming voltage required. Its integrated bootstrap loader (BSL) enables firmware updates via UART or SPI using only the standard 1.8–3.6 V supply, and code protection is enforced by a one-time security fuse - critical for secure field upgrades in deployed MSP430F2274IRHAT-based devices.
How many analog input channels does the MSP430F2274IRHAT ADC support?
The MSP430F2274IRHAT integrates a 10-bit ADC10 module with 12 selectable analog input channels (A0–A7, A12–A15), supporting autoscan mode and data transfer controller (DTC) for autonomous conversion sequencing. All channels are accessible through dedicated pins or shared with GPIO/op-amp functions - enabling simultaneous multi-sensor acquisition without external multiplexers.
Can the MSP430F2274IRHAT's op amps drive external loads directly?
Yes, both op amps (OA0 and OA1) in the MSP430F2274IRHAT are rail-to-rail output types capable of driving capacitive loads up to 100 pF and resistive loads down to 2 kΩ while maintaining stability and specified gain accuracy. Their outputs are accessible on multiple pins (e.g., P2.1, P4.3, P4.4, P4.6), allowing direct connection to ADC inputs, filters, or low-power transducers without external buffering.
What debug interface does the MSP430F2274IRHAT use, and is it compatible with standard tools?
The MSP430F2274IRHAT uses the Spy-Bi-Wire (SBW) interface - a 2-wire subset of JTAG - supported natively by TI's MSP-FET430UIF, MSP-FET430PIF, and MSP-FET430U38 debuggers. It requires only TEST/SBWTCK (Pin 1) and RST/NMI/SBWTDIO (Pin 6), enabling full flash programming, real-time breakpoints, and register inspection without dedicated JTAG cabling or footprint overhead.
