MSP430F123IDW Technical Specifications

MSP430F123IDW Key Features

• 16?bit RISC core ?? delivers compact code density and efficient integer math for control tasks and signal processing.
• Low operating voltage ?? runs from 1.8 to 3.6 V, enabling use with single?cell lithium and many standard logic rails.
• Small on?chip flash ?? 2 KB of nonvolatile storage supports compact firmware and in?system updates for simpler devices.
• Multiple low?power modes ?? reduce average system consumption in battery?powered applications and extend run time.
• Integrated 16?bit timer ?? provides precise event timing and pulse generation without external components, lowering BOM cost.
• Compact 20?pin package ?? minimizes PCB footprint while preserving up to 16 I/O lines for sensors and actuators.
• Wide temperature range ?? rated -40 ??C to +85 ??C for industrial deployments and outdoor use.

Typical Applications

• Battery?powered sensor nodes and simple data loggers that need hours to years of operation on small cells through aggressive low?power modes and compact firmware.
• Portable test equipment and handheld instruments that require deterministic timing and modest code storage for user interfaces and measurement routines.
• Simple motor or actuator control in appliances where a single 16?bit timer and multiple GPIO lines can handle PWM and state sequencing with minimal external parts.
• Embedded control for metering and utility endpoints that demand industrial temperature tolerance and low BOM cost for high?volume production runs.

MSP430F123IDW Advantages vs Typical Alternatives

The device offers a clear balance of low power, compact memory, and mixed?signal peripheral integration compared with larger 8? or 32?bit controllers. The 16?bit core often achieves smaller code size and faster integer operations than many 8?bit alternatives, while the low operating voltage and multiple standby modes reduce battery drain versus higher?clocked MCUs. In small designs where fewer I/Os, a single timer, and modest flash are sufficient, this part can lower BOM cost and PCB area compared to more feature?heavy controllers.
