MSP430FR5738IRGER Technical Specifications

MSP430FR5738IRGER Key Features

• Single 16-bit MSP430 core with low active and standby currents for extended battery life in portable systems.
• Embedded FRAM that delivers higher write endurance and lower write energy than flash, improving system reliability over many cycles.
• 12-bit ADC supporting up to 200 ksps for finer analog measurement resolution compared with lower-resolution ADCs.
• Multiple serial interfaces (UART, SPI, I2C) for flexible connectivity and simpler integration with sensors and external devices.
• Multiple timers including Timer_A and Timer_B for precise PWM generation, timing, and real-time control tasks.
• Wide 1.8?C3.6 V operating range that enables compatibility with both 3.3 V and lower-voltage systems.
• Compact 64-pin package balancing I/O density and board area for cost-sensitive, space-constrained designs.
• Industrial temperature rating that supports deployment in harsher environments compared with consumer-grade parts.

Typical Applications

• Industrial sensor nodes where frequent nonvolatile logging is required; FRAM allows many more write cycles and lower energy per log than flash storage.
• Battery-powered metering and data acquisition systems that need low active and standby current for longer field life between charges or replacements.
• Motor-control and power-conversion controllers that combine precise PWM timers and a fast 12-bit ADC for improved control loop accuracy and responsiveness.
• Human-machine interfaces and communication bridges that require UART, SPI, and I2C peripherals to interface with displays, keypads, and external peripherals reliably.

MSP430FR5738IRGER Advantages vs Typical Alternatives

The key advantage is the integrated FRAM, which provides far greater write endurance and much lower write energy than standard flash-based microcontrollers. Compared with equivalent flash MCUs, this part reduces write latency and extends nonvolatile storage lifetime, lowering maintenance and replacement costs. The 16-bit MSP430 core offers a simpler code footprint and lower active power than many 32-bit alternatives, while the 12-bit ADC and multiple serial ports improve sensor interface flexibility and reduce external component count.

FAQ

What memory type does it use?

The device uses embedded FRAM for main nonvolatile storage. FRAM delivers higher write endurance and lower energy per write than flash, which benefits frequent logging and configuration storage.

What is the supported voltage range?

The microcontroller operates over a 1.8 V to 3.6 V supply range, enabling compatibility with both low-voltage 1.8 V systems and common 3.3 V designs without external regulators in many cases.

Which serial interfaces are available?

It provides two enhanced USCI/eUSCI modules configurable for UART, SPI, and I2C modes. That lets you connect multiple sensors, memory devices, or communication links with fewer external components.

What ADC performance can I expect?

The integrated ADC is 12-bit and supports sample rates up to about 200 ksps, suitable for mid-speed sensor sampling and signal acquisition with better resolution than typical 10-bit converters.

Is this device suitable for industrial use?

Yes. The specified temperature range extends to -40 ??C to +85 ??C, matching common industrial requirements and making it suitable for deployment in harsher environmental conditions.
