MSP430G2402IRSA16R Key Features
- 16-bit core for efficient integer math and tighter code density compared with 8-bit MCUs.
- Low-voltage operation from 1.8 V to 3.6 V, enabling direct battery use and fewer power rails.
- Small flash and SRAM footprint that keeps BOM and board costs lower for simpler embedded tasks.
- Industrial temperature rating ensures reliable operation in harsh ambient conditions.
- Single 16-bit timer for precise PWM, timing, and event capture without external timers.
- Multiple low-power modes that reduce active duty-cycle energy draw for battery-powered systems.
Typical Applications
- Battery-powered sensor modules that require long standby times and periodic wake cycles for data sampling and reporting.
- Simple motor or actuator controllers that need precise timing, PWM generation, and low pin count to lower cost and complexity.
- Industrial control nodes where operation across -40 ??C to +85 ??C is required and board space must be minimized.
- Consumer and portable devices that benefit from a 16-bit CPU and ultra-low-power modes to extend runtime on small batteries.
MSP430G2402IRSA16R Advantages vs Typical Alternatives
The device offers a smaller memory and pin-count footprint versus higher-end MSP430 variants and many 32-bit MCUs. This yields lower BOM cost, reduced PCB area, and simpler power management. Compared with typical 8-bit parts, the 16-bit core often delivers better code density and faster integer processing for the same clock rate. The industrial rating and 1.8?C3.6 V range give wider deployment flexibility than consumer-only devices. Overall, it balances minimal system cost with reliable timing and low-power operation.
