MSP430F2122IRHBR Technical Specifications

MSP430F2122IRHBR Key Features

• 16-bit RISC core for efficient code density and predictable instruction timing, which reduces execution time versus 8-bit alternatives.
• Low power operation with multiple low-power modes that extend battery life in portable and remote applications.
• On-chip Flash and RAM that enable compact firmware and fast boot times without external memory, simplifying board design.
• Integrated peripherals including a 16-bit timer and a 10-bit ADC, which reduce BOM count compared to standalone components.

Typical Applications

• Battery-powered sensor nodes that require long standby lifetime and occasional measurement and wireless transmit cycles, where every microamp saved extends field life.
• Portable medical instruments that need deterministic control, small code footprint, and robust analog measurement capability for low-noise sensor interfaces.
• Digital utility meters and energy monitors that demand stable timing, reliable ADC measurements, and predictable power consumption in metering deployments.
• Industrial control panels with compact I/O, timed event control, and nonvolatile program storage for simple machine sequencing and human-machine interface tasks.

MSP430F2122IRHBR Advantages vs Typical Alternatives

The device blends a 16-bit CPU with ultra-low-power modes to deliver greater energy efficiency than many 8-bit microcontrollers. On-chip Flash and RAM reduce the need for external memory and lower total system cost. Integrated timer and ADC peripherals provide more direct hardware support than minimalist MCUs, while the 20-pin package offers denser integration than larger alternatives. This combination makes it suitable where compact size, low power, and modest analog capability are required.
