MSP430F2001IRSAR Key Features
- 16-bit CPU: Enables higher computational density than 8-bit MCUs for control tasks while keeping code compact.
- Small flash and RAM: 1 KB flash and 128 B RAM reduce cost and footprint for simple embedded applications.
- Low-voltage operation: Runs from 1.8 V to 3.6 V, allowing use with single-cell lithium or two-cell alkaline configurations.
- Timer_A: Built-in 16-bit timer supports precise timing and PWM without external components.
- Multiple low-power modes: Five sleep states to balance active performance against battery life in long-deploy systems.
- Compact I/O set: Eight GPIO pins provide basic interfacing to switches, LEDs, and simple sensors with minimal pin count.
Typical Applications
- Portable sensor nodes that require ultra-low power draw and simple control loops with long battery life in remote deployments.
- Battery-powered consumer devices such as key fobs and simple remotes where cost, size and low standby current matter most.
- Industrial monitoring endpoints that need a small MCU to sample events, debounce inputs, and communicate status with minimal BOM.
- Appliance control tasks that require precise timing, low-power standby states, and a compact microcontroller footprint to lower system cost.
MSP430F2001IRSAR Advantages vs Typical Alternatives
The device offers a stronger power-versus-performance balance than many 8-bit controllers by using a 16-bit core at typical clock rates up to 16 MHz. With 1 KB flash and 128 bytes of RAM, it is smaller and lower cost than larger MSP430 variants while providing more computational headroom than basic microcontrollers. Its multiple low?power modes and sub-3.6 V operation make it ideal for battery-first designs where energy per operation and reduced component count matter most.
