MSP430G2403IRHB32T Technical Specifications

MSP430G2403IRHB32T Key Features

• 16-bit RISC core ?? delivers efficient instruction throughput for control loops and protocol handling with lower code size than many 8-bit parts.
• Low-voltage operation ?? runs from 1.8 V to 3.6 V, enabling compatibility with single-cell lithium and two-cell alkaline power systems.
• Small 32-pin package ?? packs more I/O and peripherals into a compact footprint for space-constrained boards.
• Multi-level low-power modes ?? reduces static and dynamic power to extend battery life in intermittent or always-on systems.

Typical Applications

• Battery-operated sensor nodes where >24 I/O lines and multi-mode power management extend field life while keeping BOM costs low.
• Small industrial controllers that require deterministic timing, modest code memory and robust temperature range for steady operation.
• Consumer handheld devices that need low active current, compact package size and flexible I/O for buttons, LEDs and simple displays.
• Embedded metering and data-loggers where efficient 16-bit computation and multiple sleep states reduce energy use between samples.

MSP430G2403IRHB32T Advantages vs Typical Alternatives

The device targets a middle ground between tiny 8-bit MCUs and larger 32-bit controllers. It offers lower dynamic power per MHz than many 8-bit cores while keeping board size smaller and cost lower than full-featured 32-bit MCUs. With a 16-bit RISC core, multiple low-power modes and a 32-pin package, it provides more GPIO and integration than minimal packages, and better battery life than higher-clocked alternatives. Those trade-offs make it suitable for designs that need efficient compute and I/O density without extra complexity.
