MSP430G2101IPW14 Technical Specifications

MSP430G2101IPW14 Key Features

• Single 16-bit MSP430 core with low instruction cycle counts for faster control loops and lower energy per operation.
• Wide operating voltage of 1.8?C3.6 V which supports more battery chemistries and wider system tolerances.
• Compact 14-pin TSSOP package for smaller PCB footprint compared with many 20?C40 pin controllers.
• Integrated 16-bit Timer_A for precise timing, PWM generation, and event capture without external components.
• Multiple low-power modes (LPM0?CLPM3) to reduce current draw when idle and extend battery life in portable systems.
• On-chip nonvolatile memory (1 KB) and SRAM (128 B) to store firmware and small runtime data with fast code execution.
• Hardware watchdog for improved reliability and system recovery in noisy or unattended environments.
• Industrial temperature rating (-40 ??C to +85 ??C) for deployment in harsher conditions versus consumer-only parts.

Typical Applications

• Battery-powered sensor nodes that require ultra-low standby current and a small package to reduce BOM cost and board area in wireless sensor networks.
• Simple user-interface controllers for handheld meters, where basic input buttons, LED indicators, and timing functions are needed with low power.
• Basic motor or actuator control in small appliances, using the 16-bit timer for PWM and event timing without a larger MCU.
• Industrial monitors and interrupters that need a rugged device with industrial temperature range and watchdog supervision for unattended operation.

MSP430G2101IPW14 Advantages vs Typical Alternatives

The MSP430G2101IPW14 delivers a better power-to-performance ratio than many 8-bit microcontrollers. Its 16-bit core executes arithmetic and control code with fewer cycles, often reducing system latency by 20?C50% for the same algorithms. The device is smaller and cheaper than many higher-pin MCUs while keeping key features like a 16-bit timer and integrated watchdog. Industrial temperature rating and a low-voltage range of 1.8?C3.6 V make it more tolerant of harsh conditions than consumer-grade devices.
