MSP430F1222IPWR Key Features

• One 16-bit CPU core that delivers efficient instruction density and faster execution for control tasks.
• On-chip flash memory plus RAM, which reduces external memory needs and lowers BOM cost.
• Multiple low-power modes that extend battery life and cut standby current compared to typical 8-bit alternatives.
• Integrated 10-bit ADC and a 16-bit timer for compact sensing and timing solutions without extra components.

Typical Applications

• Battery-powered sensor nodes where low standby current and longer runtime are required, reducing maintenance and service intervals.
• Portable instruments that need compact processing with on-chip ADC and timers for analog measurement and precise timing control.
• Appliance control panels that require multiple GPIOs and low-voltage operation to support safer, smaller power supplies.
• Industrial monitoring endpoints that benefit from a small package, robust temperature range, and integrated peripherals for fewer external parts.

MSP430F1222IPWR Advantages vs Typical Alternatives

The device offers a 16-bit core and integrated peripherals in a smaller 20-pin footprint, which often means fewer external components and lower system cost than many 8-bit MCUs. With an operating range from 1.8 V to 3.6 V and multiple low-power modes, it provides lower active and standby power than many older microcontrollers. Designers gain better instruction density, more precise ADC measurements, and simpler board layouts compared with discrete-solution alternatives.

FAQ

What package does it use?

The part is available in a 20-pin TSSOP package (PWR). This smaller package saves PCB area compared with wider packages and simplifies routing for compact designs.

What voltage range is supported?

It supports a wide operating voltage range from 1.8 V to 3.6 V. That range enables compatibility with more battery chemistries and modern low-voltage power rails.

How much nonvolatile memory is onboard?

On-chip flash memory is 2 KB (2048 bytes). That capacity supports modest firmware and reduces the need for external code storage for many embedded control tasks.

What analog peripherals are included?

The device integrates a 10-bit ADC and analog input channels. This lets you measure voltages with better resolution than many 8-bit ADCs without adding discrete ADC chips.

Is it suitable for battery operation?

Yes. Multiple low-power modes and a low-voltage operating range make it suitable for battery-powered applications where lower standby and active currents extend service life.
