MSP430F2274IDA

MSP430F2274IDA is a member of TI’s MSP430 ultra‑low‑power microcontroller family (MSP430x2xx). It uses a 16‑bit RISC CPU designed for very low current operation, with built‑in flash program memory, RAM, and a rich set of peripherals. The “IDA” suffix denotes a specific package/variant for this part (check TI’s package code for exact pin count and form factor).
Typical peripherals (varies by package) include:
- Timers, and basic I/O ports
- USCI module for serial communication (UART/SPI/I2C)
- Analog features such as ADC and comparators
- Watchdog timer and clock system
Key advantages:
- Multiple low‑power modes with fast wake‑up for extended battery life
- Wide operating voltage range (typically around 1.8–3.6 V, depending on package)
- Simple development flow with Code Composer Studio (C/C++ and assembly)
Common applications: battery-powered sensors, data loggers, wearables, portable instruments.
For exact specs (flash/RAM sizes, pin count, peripherals), refer to the MSP430F2274 datasheet and user guide on TI’s website. The IDA designation is a hardware/package variant, not a change to core features.

MSP430F2274IDA features (concise):
- 16-bit MSP430 CPU (RISC, Harvard architecture) for low-power operation
- Wide voltage range: 1.8–3.6 V
- Clock: DCO-based, up to tens of MHz (typical MSP430 speeds in this family)
- Memory: Flash program memory (KBs to over 100 KB range, device variant dependent) + RAM (several KB)
- Analog: 12-bit ADC with multiple input channels; analog comparator with reference
- Timers: several 16-bit timers with PWM and capture/compare
- Communication: two USCI modules (USCI_A and USCI_B) for UART, SPI, and I2C
- Peripherals: watchdog timer, brown-out detector
- Low-power: multiple low-power modes (LPM0–LPM4) with fast wake-up
- Package: IDA indicates a 100-pin package (100-pin LQFP/TQFP variant)
- Temperature range: typical industrial range (-40 to 85°C)
- Development support: Code Composer Studio or IAR, TI MSP430 development libraries
Note: exact memory sizes, clock speed, and peripheral counts depend on the specific device revision and package.

MSP430F2274IDA uses a 64-pin LQFP (QFP) package.

- Pin count: 100 pins (LQFP-100 package; suffix IDA indicates the package variant).
- Function: MSP430 16-bit microcontroller (MSP430 family) with onboard Flash RAM and integrated peripherals (timers, ADCs, communication interfaces such as UART/SPI/I2C, etc.).
