MSP430F5526IZXHR Technical Specifications

MSP430F5526IZXHR Key Features

• Single 16-bit MSP430 core running up to 25 MHz for responsive control and low instruction overhead.
• On-chip USB 2.0 full-speed controller, reducing external components and simplifying host/device connectivity.
• Integrated 12-bit ADC and analog front-end to support precision sensing with fewer external parts.
• Built-in DMA support to offload data movement and improve efficiency for high-throughput peripherals.

Typical Applications

• Industrial USB-connected sensors and data loggers where reliable USB 2.0 transfer and low power are required over long deployment lifetimes.
• Portable instruments that need accurate 12-bit analog measurement and low standby currents to extend battery life in field use.
• Human-machine interface modules that combine serial comms, timers for PWM-driven LEDs/actuators, and compact code storage in Flash.
• Embedded control nodes in automation where integrated peripherals reduce BOM and provide deterministic control at up to 25 MHz.

MSP430F5526IZXHR Advantages vs Typical Alternatives

The device delivers a compact 16-bit architecture with comparable performance but lower active and standby currents than many 32-bit alternatives. With an integrated USB 2.0 controller and on-chip 128 KB Flash / 8 KB RAM, it often replaces designs that require external USB interfaces and extra memory. The wide supply range (1.8?C3.6 V) and industrial-temperature rating make it more flexible than many consumer-only MCUs. Built-in DMA and multiple serial ports improve throughput and reduce CPU load versus simpler microcontrollers.

FAQ

What supply voltage does it need?

The device operates from 1.8 V to 3.6 V. That range supports common battery chemistries and 3.3 V system rails while allowing lower-voltage operation to save power.

Does it support USB connectivity?

Yes. It includes a full-speed USB 2.0 interface (12 Mbps) implemented on-chip. That reduces external USB PHY parts and simplifies USB device or host designs.

What ADC accuracy is available?

The MCU includes a 12-bit successive-approximation ADC suitable for medium-accuracy sensing. On-chip sampling and conversion reduce external circuitry for many measurement tasks.

Is it suitable for industrial temperatures?

Yes. The device supports an industrial operating range from -40 ??C to +85 ??C, making it appropriate for factory-floor and outdoor embedded systems.

How does it handle data transfers efficiently?

It provides an integrated DMA controller and multiple serial peripherals. DMA moves data without CPU intervention, which improves throughput and reduces active power for high-rate peripherals.
