MSP430F2002IRSAT Key Features

• 16?bit RISC core ?? delivers compact code and efficient control for small embedded tasks.
• Low voltage operation ?? 1.8?C3.6 V range enables direct battery use and fewer power rails.
• Small flash and RAM ?? 2 KB flash and 128 B RAM reduce BOM cost while supporting tight firmware footprints.
• Single 16?bit Timer_A ?? provides precise timing, PWM and capture/compare for real?time control.
• USI serial block ?? flexible basic SPI/I2C/UART, which eases integration with sensors and peripherals.
• Industrial temp rating ?? ?40 ??C to +85 ??C supports outdoor and harsher industrial use more reliably than consumer?grade parts.

Typical Applications

• Battery?powered sensor nodes where low supply voltage and single?timer control keep hardware simple and energy use low for long field life.
• Portable handheld instruments that require a compact MCU for UI control, timing and basic serial comms without large memory overhead.
• Appliance controllers performing simple state machines, PWM fan control, and watchdog supervision with minimal component count and software size.
• Industrial monitoring endpoints that need robust temperature range, isolated I/O and low standby draw to extend maintenance intervals.

MSP430F2002IRSAT Advantages vs Typical Alternatives

The device favors low power and low cost over raw feature count. Compared with larger 32?bit MCUs, it requires far less flash and RAM, reducing BOM and firmware complexity for simple tasks. Compared with similar 8?bit devices, its 16?bit core offers more efficient arithmetic and tighter code density for control algorithms. The single 16?bit timer and USI block provide just enough peripherals to integrate sensors and actuators with fewer external ICs, improving system reliability and lowering unit cost.
