MSP430G2212IPW20 Technical Specifications

MSP430G2212IPW20 Key Features

• One 16-bit CPU core for compact code density and faster arithmetic compared with 8-bit alternatives.
• Integrated Timer_A that enables precise event timing and PWM generation, which matters for motor control or power sequencing.
• Low-voltage operation from 1.8 to 3.6 V for compatibility with single-cell battery systems and tighter power budgets.
• Ultra-low-power sleep modes that reduce standby current and extend battery life for remote, always-on, or energy-harvested applications.
• Universal serial interface to support SPI and I2C-like connectivity, simplifying integration with sensors and peripherals.
• Small 20-pin package for compact board area and easier placement in space-constrained designs.

Typical Applications

• Battery-powered sensor nodes that require years of operation with low average current and occasional timed wake-ups for measurement and reporting.
• Handheld instruments and portable measurement tools where compact size, 16-bit processing, and low supply current improve runtime and responsiveness.
• Simple motor or actuator control where Timer_A PWM and capture/compare features provide deterministic timing for position or speed regulation.
• Industrial control endpoints and communication interfaces that need robust operation across -40 ??C to +85 ??C and reliable serial links to system controllers.

MSP430G2212IPW20 Advantages vs Typical Alternatives

The device offers a tighter power-to-performance ratio than many 8-bit microcontrollers. With a 16-bit core and up to 16 MHz operation, it delivers higher data throughput and smaller code size for arithmetic and control tasks. Its 1.8?C3.6 V range and multiple low-power modes make it more suitable for single-cell battery and energy-harvested systems than parts that require higher voltages or lack deep-sleep states. The 20-pin package also reduces board area compared with larger MCUs while still providing essential timers and a USI for common serial protocols.

FAQ

What is the supply voltage range?

The device operates from 1.8 V to 3.6 V. This range supports single-cell lithium and many low-voltage battery chemistries, enabling direct battery connection in portable designs without extra regulation.

How much program memory is available?

Program storage is 2 KB of Flash. That size suits compact firmware, control loops, and protocol stacks where minimal code footprint and in-field update capability are needed.

What serial interfaces are available?

It provides a Universal Serial Interface (USI), which can be used for SPI-style and I2C-style communication. USI simplifies sensor and peripheral interfacing while saving pins compared with multiple dedicated modules.

What package and pin count should I expect?

The product comes in a 20-pin TSSOP package. The compact footprint supports small PCBs and keeps pin routing simpler for low-pin-count applications.

Is the device suitable for industrial temperatures?

Yes. The specified operating range extends from -40 ??C to +85 ??C, covering common industrial requirements for reliable operation in harsh temperature conditions.
