MSP430F5522IZXHR Technical Specifications

MSP430F5522IZXHR Key Features

• Single 16?bit MSP430 core with low active and standby currents for longer battery life in portable and meter applications.
• Integrated USB 2.0 full?speed controller, reducing the need for an external USB PHY and lowering BOM cost for USB?enabled designs.
• 12?bit ADC and on?chip analog peripherals to capture sensor data with fewer external components and tighter system integration.
• Wide supply range and industrial temperature rating for reliable operation across more environments and use cases.

Typical Applications

• USB?connected data loggers and handheld instruments that require low power, integrated USB, and precision analog conversion for sensor acquisition.
• Industrial human?machine interfaces and control panels that need reliable full?speed USB communication and a compact memory footprint for firmware.
• Energy metering and smart sensor gateways that benefit from the mixed?signal peripherals and low standby power to extend operational lifetime.
• Portable medical instruments requiring stable analog measurement, secure USB data transfer, and a small package for dense PCB layouts.

MSP430F5522IZXHR Advantages vs Typical Alternatives

The device offers more integrated USB and analog capability than many competing 8?bit MCUs, and lower active power than many 32?bit alternatives at similar clock rates. With up to 128 KB of flash and 8 KB of RAM, it provides more program and buffer space than entry?level microcontrollers. The wide 1.8?C3.6 V supply range and industrial temperature rating deliver more robust deployment options. These attributes translate into fewer external parts, lower BOM cost, and simpler board routing for designers.
