Product details
Overview
MSP430F2274IDA 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 internal 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 MSP430F2274IDA datasheet, MSP430F2274IDA pinout, MSP430F2274IDA application, or MSP430F2274IDA equivalent, key selection considerations include its DA-package 38-pin TSSOP footprint, dual op-amp support (MSP430F22x4 family), LPM4 ultra-low-power mode (0.1 µA RAM retention), and integrated brownout detector with programmable threshold.
Technical Context
The MSP430F2274IDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies (±1%), plus support for 32-kHz crystal, HF crystal up to 16 MHz, resonator, or external digital clock source.
Peripherals are memory-mapped and accessible via standard instructions. The device supports five software-selectable low-power modes (LPM0–LPM4), with wake-up from standby in <1 µs. Interrupt handling uses fixed vector addresses (0FFFEh–0FFC0h), including dedicated vectors for Timer_A3, Timer_B3, USCI_A0/B0, ADC10, and port interrupts.

FAQ
What is the maximum operating frequency of the MSP430F2274IDA?
The MSP430F2274IDA supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal DCO calibrated to ±1% or an external HF crystal. This allows deterministic real-time processing while maintaining ultra-low power consumption - for example, executing 16 million instructions per second with only 270 µA current draw at 2.2 V supply.
Does the MSP430F2274IDA include hardware debug capability?
Yes, the MSP430F2274IDA integrates an Embedded Emulation Module (EEM) supporting full-speed debugging and flash programming via the two-wire Spy-Bi-Wire interface using only RST/NMI/SBWTDIO and TEST/SBWTCK pins. No external JTAG header is required, simplifying PCB layout and reducing test point count.
How many analog input channels does the MSP430F2274IDA ADC support?
The MSP430F2274IDA features a 10-bit ADC10 module with 12 selectable analog input channels (A0–A7, A12–A15), plus internal temperature sensor and VCC/2 references. Channel selection is fully programmable, and autoscan mode enables sequential conversion of up to 16 values without CPU intervention - ideal for multi-sensor monitoring.
Is the MSP430F2274IDA pin-compatible with other MSP430F22x4 variants in the DA package?
Yes, all MSP430F22x4 devices (including MSP430F2234IDA, MSP430F2254IDA, and MSP430F2274IDA) share identical pinouts in the 38-pin DA (TSSOP) package. Firmware and PCB designs can be reused across this family - only flash size, RAM size, and op-amp presence differ, with no impact on I/O mapping or peripheral register layout.
What development tools are recommended for the MSP430F2274IDA?
Texas Instruments recommends the MSP-FET430U38 debugger/programmer - a DA-package-specific target board with integrated MSP-FET430UIF interface - for rapid prototyping. Production programming is supported by the MSP-GANG430 gang programmer. All tools leverage the device's built-in BSL and EEM for zero-cost firmware updates and field reprogramming.
