MSP430G2212IN20 Technical Specifications

MSP430G2212IN20 Key Features

• Single 16-bit core with compact instruction set that delivers efficient code density and faster interrupt response for simple control loops.
• Low-voltage operation (1.8?C3.6 V) that reduces battery stress and supports a wider range of battery chemistries for longer run times.
• Small PDIP-20 package for easy prototyping and legacy board compatibility, which simplifies replacement in 20-pin designs.
• Integrated timer and USI serial interface that enable low-pin-count UART/SPI/I2C-style communications without external controllers.
• Industrial temperature rating (-40 ??C to 85 ??C) for reliable operation in harsher environments compared to consumer-grade parts.
• Very low standby current characteristics that minimize power draw in sleep modes for battery-powered applications.

Typical Applications

• Simple sensor node controllers in remote monitoring systems where low quiescent current extends battery life and reduces maintenance frequency.
• Handheld instruments and handheld user interfaces that need a compact MCU with a small pin count and low system cost for mass deployment.
• Appliance and industrial control tasks that require a rugged temperature range and straightforward timing or serial communications functions.
• Legacy system upgrades and educational boards that benefit from a 20-pin PDIP footprint for quick swaps and easy breadboard prototyping.

MSP430G2212IN20 Advantages vs Typical Alternatives

The device offers a tighter fit between cost and functionality than many 8-bit alternatives. Its 16-bit core gives more headroom for arithmetic and control tasks at comparable clock rates. Compared with larger 32-bit MCUs, it consumes far less power and requires fewer external components. The PDIP-20 package and industrial temperature rating make it more convenient for maintenance and field service in industrial deployments.

FAQ

What is the maximum clock speed?

The maximum core clock is 16 MHz. This clock rate supports common control and communication tasks while still allowing low-power mode operation for battery-powered systems.

Which package does it come in?

The part number suffix indicates a 20-pin PDIP package. That package simplifies prototyping and replacement on existing through-hole boards compared with surface-mount-only variants.

What voltage range is supported?

Supply operation ranges from 1.8 V up to 3.6 V. That range supports single-cell lithium or two-alkaline-cell designs while maintaining stable core and peripheral operation.

Is it suitable for industrial environments?

Yes. The device is rated for an industrial temperature range of -40 ??C to 85 ??C, making it suitable for many factory and field environments where wider thermal margins are required.

Which serial interfaces are available?

The MCU includes a USI (Universal Serial Interface) that supports UART-like, SPI-like, and I2C-like protocols. This reduces the need for external level shifters or bridge ICs in simple communications applications.
