Product details
Overview
MSP430F2274MRHATEP from Texas Instruments is an ultralow-power mixed-signal microcontroller with 32KB flash, 1KB RAM, 10-bit 200-ksps ADC with DTC, two configurable op amps, and dual 16-bit timers (Timer_A3 and Timer_B3), operating across –55°C to 125°C for radiation-tolerant defense and aerospace sensor systems.
For engineers reviewing the MSP430F2274MRHATEP datasheet, MSP430F2274MRHATEP pinout, MSP430F2274MRHATEP application, or MSP430F2274MRHATEP equivalent, key selection criteria include extended temperature support, integrated analog signal conditioning, ultrafast wake-up (<1 µs), and Spy-Bi-Wire debug compatibility in a 40-pin QFN package.
Technical Context
The MSP430F2274MRHATEP implements a 16-bit RISC CPU with six low-power modes, digitally controlled oscillator (DCO) calibrated at 1/8/12/16 MHz ±1%, and dual clock domains (ACLK, MCLK, SMCLK) supporting crystal, resonator, or external digital sources. Its basic clock module enables operation from –55°C to 125°C using internal LF oscillator or 32-kHz crystal.
It integrates USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), ADC10 with autoscan and data transfer controller (DTC), brownout detection, and on-chip emulation logic. The two operational amplifiers (OA0/OA1) are software-configurable for front-end signal conditioning prior to ADC sampling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2272MRHATEP | 16KB flash, same 1KB RAM, identical peripherals and pinout - lacks second op amp (OA1). | Suitable for cost-sensitive designs where single-op-amp signal conditioning suffices. | Select when flash requirement ≤16KB and dual-op-amp functionality is unnecessary. |
| MSP430F2617TPM | 116KB flash, 8KB RAM, enhanced USCI, but commercial temp range (–40°C to 85°C) and no EP qualification. | Targeted at industrial automation with higher code density needs, not radiation-tolerant environments. | Choose only if extended temperature and defense-grade traceability are not required. |
Compared with MSP430F2274MRHATEP, the F2272MRHATEP offers identical packaging and interface compatibility at lower memory cost, while the F2617TPM provides greater processing headroom but sacrifices military-grade environmental robustness and supply chain assurance.

FAQ
What is the maximum operating frequency of the MSP430F2274MRHATEP?
The MSP430F2274MRHATEP supports internal DCO frequencies up to 16 MHz, factory-calibrated to ±1% across its full temperature range. It also accepts external high-frequency crystals up to 16 MHz or digital clock sources, enabling precise timing for ADC sampling, UART baud generation, and real-time control loops in the MSP430F2274MRHATEP.
Does the MSP430F2274MRHATEP support JTAG debugging?
No - the MSP430F2274MRHATEP uses Spy-Bi-Wire (2-wire) interface exclusively for programming and debugging via TEST/SBWTCK and RST/NMI/SBWTDIO pins. This reduces PCB footprint and simplifies test access compared to traditional 4-wire JTAG, while maintaining full flash erase/write and breakpoint capability in the MSP430F2274MRHATEP.
How many analog input channels does the ADC10 module support in the MSP430F2274MRHATEP?
The ADC10 module in the MSP430F2274MRHATEP supports 12 dedicated analog input channels (A0–A7, A12–A15), plus internal references and op amp outputs. Channel selection is fully programmable, and autoscan mode enables sequential conversion across up to 16 inputs without CPU involvement - a core capability of the MSP430F2274MRHATEP.
Is the MSP430F2274MRHATEP pin-compatible with other devices in the MSP430F22xx family?
Yes - the MSP430F2274MRHATEP shares identical 40-pin QFN (RHA) package and pinout with MSP430F2272MRHATEP and MSP430F2234MRHATEP. This enables hardware reuse across variants differing only in flash size (16KB/32KB) and op amp count (1/2), simplifying design scalability and inventory management for the MSP430F2274MRHATEP.
What security features protect flash memory in the MSP430F2274MRHATEP?
The MSP430F2274MRHATEP includes programmable code protection via a security fuse, bootstrap loader (BSL) password enforcement, and flash segment locking. Segment A contains factory calibration data and is protected by default after reset. These mechanisms prevent unauthorized readout or modification of firmware in the MSP430F2274MRHATEP deployed in secure or safety-critical systems.
