MSP430G2402IN20 Technical Specifications

MSP430G2402IN20 Key Features

• 16-bit RISC core for higher computational density and simpler code than many 8-bit MCUs.
• Low-voltage operation across 1.8?C3.6 V, which enhances battery runtime compared with devices requiring higher supply voltages.
• Compact 20-pin TSSOP package that reduces board area versus larger packages while keeping more pins than the smallest SOT designs.
• Small flash and RAM sized for cost-sensitive embedded tasks, enabling lower BOM cost compared with larger-memory variants.
• 16-bit Timer_A that supports precise timing, PWM generation, and event counting for real-time control functions.
• Multiple low-power modes to minimize energy consumption in sleep states and extend battery life in intermittent-activity systems.
• Simplified peripheral set that lowers integration complexity and speeds up development for basic sensing and control nodes.

Typical Applications

• Battery-powered sensor nodes for environmental monitoring where low standby current and a small footprint reduce system cost and extend runtime.
• Simple human-interface devices such as 1?C4 button remote controls that need low-cost control, debouncing, and timer-driven sleep/wake sequences.
• Basic motor or actuator control for small appliances where a 16-bit timer provides PWM and timing without a large MCU footprint.
• Power management and metering front-ends that require accurate timing, low-voltage operation, and compact packaging for space-constrained PCBs.

MSP430G2402IN20 Advantages vs Typical Alternatives

The device offers a clear trade-off: more processing headroom than basic 8-bit MCUs while keeping cost and power below larger 32-bit options. With a 16-bit core and up to 16 MHz operation, it delivers faster integer math and tighter timing than 8-bit parts. Its 1.8?C3.6 V supply range and multiple low-power modes make it better for longer battery life. The 20-pin TSSOP package provides more I/O and peripherals than minimal SOT or DIP packages, yet takes less PCB area than many larger controllers.

FAQ

What is the core architecture?

The device uses a 16-bit RISC CPU. This core gives more arithmetic precision and narrower code for control tasks than typical 8-bit microcontrollers.

What supply voltage is required?

The supported supply range is 1.8 V to 3.6 V. This allows operation from single-cell lithium or multiple alkaline cells with simple regulation schemes.

How much program memory does it provide?

Program storage is 2 KB of on-chip flash. That capacity is intended for compact firmware targeting simple sensing, timing, and control functions.

Which package should I expect for procurement?

The part is offered in a 20-pin TSSOP package (IN20). That package balances PCB area, pin count, and thermal handling for industrial and consumer boards.

Where can I find development tools and documentation?

Reference documentation, development tools, and example code are available from Texas Instruments. Use TI??s MSP430 software tools and application notes for development and evaluation.
