MSP430F2252IRHAR Technical Specifications

MSP430F2252IRHAR Key Features

• 16?bit core delivers twice the data width of common 8?bit MCUs, enabling faster arithmetic and simpler peripheral handling.
• On?chip flash and SRAM reduce board count and BOM cost while enabling field firmware updates and parameter storage.
• Ultra?low?power operation with five low?power modes makes long battery life feasible for meters and sensors.
• Integrated 10?bit ADC and Timer_A provide tighter analog sampling and precise timing without external chips.
• Small 20?pin package offers high integration in a compact footprint for space?constrained PCBs.

Typical Applications

• Battery?powered sensor nodes that require efficient sleep/wake cycles, low standby current and on?chip ADC for analog sensors.
• Portable instrumentation where compact 20?pin packages and integrated flash reduce board area and total component count.
• Industrial control endpoints that need deterministic timers and a 16?bit CPU for simple control loops and counting tasks.
• Consumer metering and remote telemetry systems needing nonvolatile code storage and multiple low?power modes for long battery life.

MSP430F2252IRHAR Advantages vs Typical Alternatives

The device combines a 16?bit core and integrated analog/peripheral functions in a smaller package than many 32?bit MCUs, and it consumes far less power than comparable 8?bit or 32?bit alternatives during standby. With on?chip flash and SRAM, it needs fewer external components than designs using discrete memory. The built?in 10?bit ADC and 16?bit timer reduce BOM cost versus systems that require external converters and timers.
