MSP430G2221IRSA16T Technical Specifications

MSP430G2221IRSA16T Key Features

• 16-bit RISC core that delivers compact code density and efficient arithmetic, reducing cycle counts compared with many 8-bit MCUs.
• Low operating voltage range (1.8?C3.6 V) so the part integrates easily into single-cell lithium or multi-cell alkaline designs.
• Five distinct low-power modes for fine-grained power management and extended battery life in intermittent or always-on systems.
• Small 16-pin TSSOP package for reduced PCB area and simpler board layout in space-constrained assemblies.
• Industrial temperature rating (?C40 ??C to +85 ??C) for reliable deployment in harsher environments compared with consumer-grade parts.
• Tape-and-reel supply format supports automated pick-and-place assembly and higher-volume manufacturing throughput.

Typical Applications

• Battery-powered sensor nodes that demand multi-day or multi-month runtimes by using several low-power modes and short wake intervals for sampling.
• Portable measurement instruments where a 16-bit core helps with integer math and fixed-point algorithms while keeping energy use lower than many higher-clocked MCUs.
• Industrial control interfaces that require reliable operation across ?C40 ??C to +85 ??C and benefit from compact TSSOP packaging to save PCB space.
• Consumer or medical peripherals that need precise timing control and low standby current for longer shelf life and reduced maintenance frequency.

MSP430G2221IRSA16T Advantages vs Typical Alternatives

The part combines a 16-bit core and multiple power modes to offer better computational efficiency and lower energy per operation than many 8-bit MCUs. Its 1.8?C3.6 V range and industrial temperature rating allow broader system-level choices and deployment in harsher conditions compared with consumer-only devices. The 16-pin TSSOP footprint reduces board area versus larger packages while tape-and-reel availability simplifies automated assembly for medium to high volumes. Overall, it balances low power, compact size, and industrial robustness.
