MSP430FR68791IPZR

Microcontrollers Overview

The MSP430FR68791IPZR is a 16-bit ultra-low-power microcontroller from Texas Instruments, featuring the MSP430 core. It integrates 128 KB of FRAM and 2 KB of SRAM within an LQFP-100 package. The device supports a maximum clock frequency of 16 MHz and operates on a supply voltage range of 1.8 V to 3.6 V. It includes a 12-bit ADC with 16 channels, 83 I/O pins, and standard communication interfaces including UART, SPI, and I2C. The operating temperature range extends from -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates non-volatile FRAM for data retention without power cycling
• Supports high-resolution analog signal acquisition via 16-channel 12-bit ADC
• Provides extensive digital connectivity through multiple serial communication peripherals

Microcontrollers Applications

• Smart metering systems requiring precise energy measurement
• Industrial control applications needing robust data logging
• Portable instrumentation utilizing low-power operation modes

Microcontrollers Procurement Notes

Verify that the ordering suffix IPZR corresponds to the tape-and-reel packaging format rather than the tray configuration. Confirm RoHS compliance status and check for specific environmental certifications required by your manufacturing process. Ensure the component matches the active lifecycle status indicated in official Texas Instruments documentation before finalizing procurement plans.

Microcontrollers Selection Notes

Select this model when FRAM endurance and density are critical compared to traditional Flash-based alternatives. Consider the 16 MHz processing speed sufficient for real-time signal processing tasks. Evaluate the 100-pin LQFP footprint against available PCB space constraints. Compare peripheral counts against simpler variants if cost reduction is necessary while maintaining similar architecture.

Microcontrollers Part Context

This part belongs to the MSP430FR68xx family of ultra-low-power mixed-signal microcontrollers. It shares architectural similarities with other members like the MSP430FR6879 but differs in memory size and pin count. The FRAM technology distinguishes it from older MSP430F series devices which utilize Flash memory, offering faster write speeds and higher endurance characteristics for data-intensive applications.

Microcontrollers Replacement Considerations

The MSP430FR68791IPZ serves as the tray-packaged equivalent. For direct functional substitution within the same package type, verify availability of the IPN variant. Cross-reference with MSP430FR6879 series components for potential upgrades or downgrades depending on specific memory or interface requirements.
