MSP430F5509IRGZT Key Features

• 16-bit core for compact code and higher instruction efficiency compared to 8-bit controllers.
• Integrated USB full-speed enabling direct USB device connectivity at 12 Mbps without external PHY, which simplifies BOM and design.
• Large on-chip flash and SRAM (128 KB flash, 8 KB RAM) for more firmware and buffer space than many low-end MCUs in the same power class.
• Low-voltage operation from 1.8 to 3.6 V for broader battery compatibility and robust performance across supply ranges.
• Multiple 16-bit timers and ADC for precise timing and analog measurement tasks, improving measurement resolution and control loops.
• Industrial temperature rating suitable for extended-temperature applications compared with consumer-grade parts.

Typical Applications

• USB-enabled battery-powered sensors and data loggers that require low active current and direct USB connectivity for data transfer and charging.
• Portable instruments and handheld test equipment needing compact code size, reliable ADC performance, and consistent operation between 1.8 V and 3.6 V.
• Human-machine interfaces and keypad controllers that use multiple timers and serial interfaces while minimizing standby power for longer battery life.
• Embedded industrial controllers where USB device connectivity, extended temperature operation, and mid-range memory are required for firmware and data buffering.

MSP430F5509IRGZT Advantages vs Typical Alternatives

The device combines a 16-bit MSP430 core with full-speed USB and 128 KB of flash, giving designers more onboard code space than many simpler low-power MCUs. It operates down to 1.8 V, which expands compatibility with smaller batteries and lower-voltage systems. With integrated ADC and multiple 16-bit timers, the part reduces external components and board area compared with designs that require USB bridging chips or separate analog front ends. The extended industrial temperature range further suits robust embedded and field-deployed applications.
