MSP430G2111IRSA16T Technical Specifications

MSP430G2111IRSA16T Key Features

• Single 16-bit core: delivers efficient integer math and control code in fewer cycles versus 8-bit alternatives.
• Wide supply range (1.8?C3.6 V): supports common coin cells and rechargeable battery chemistries for portable systems.
• Low-power operation: standby and active modes extend battery life in long-lived sensor applications.
• Compact 16-pin package: simplifies board layout and reduces BOM cost for space-constrained designs.
• On-chip Timer_A: enables accurate timing, PWM and event scheduling without external components.
• USI serial block: supports SPI or I2C-like protocols for sensor and peripheral interfacing with fewer pins.
• Integrated watchdog and reset: improves reliability in unattended or remote deployments.

Typical Applications

• Battery-powered sensor nodes that require multi-year operation and simple control loops while minimizing BOM size and power draw.
• Handheld consumer devices that need responsive control, basic user interfaces and low supply current to preserve battery life.
• Industrial monitoring endpoints with limited I/O that must survive -40 ??C to +85 ??C and provide reliable periodic sampling and reporting functions.
• Embedded controllers for appliances or power management where a small package and single 16-bit core deliver faster ISR handling than many 8-bit devices.

MSP430G2111IRSA16T Advantages vs Typical Alternatives

The part combines a 16-bit CPU with ultra-low-power modes and a 1.8?C3.6 V supply window, offering higher instruction efficiency and broader battery compatibility than many 8-bit MCUs. Its 16-pin footprint reduces board area and cost versus larger packages. Integrated timer and USI reduce external components. For applications where modest code size and low standby current matter, this device often provides better power-per-performance and simpler system integration than bulkier general-purpose microcontrollers.
