MSP430FR5994IRGZR

Microcontrollers Overview

The MSP430FR5994IRGZR is a 16-bit microcontroller from the Texas Instruments MSP430 family, housed in a VQFN-48 package. It features a maximum clock frequency of 16 MHz and utilizes Ferroelectric Random Access Memory (FRAM) for program storage with a capacity of 256 kB. The device includes 8 kB of SRAM data memory and supports an operating voltage range of 1.8 V to 3.6 V. It provides 40 general-purpose I/O pins and integrates an 18-channel, 12-bit Analog-to-Digital Converter (ADC). Communication interfaces include I2C, SPI, and UART. The component operates within a temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

• Integrates nonvolatile FRAM technology for high endurance and low-power data retention.

Microcontrollers Applications

• Embedded systems requiring nonvolatile memory without flash erase cycles
• Low-power sensor nodes utilizing analog input capabilities
• Industrial control units using serial communication protocols

Microcontrollers Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the VQFN-48 package and tape-and-reel packaging configuration. Confirm that the ordering part number matches the required pin count and interface availability. Ensure compatibility with the target PCB footprint for the VQFN-48 form factor before finalizing procurement.

Microcontrollers Selection Notes

Select this model when a balance of moderate code space and robust analog connectivity is required in a compact surface-mount package. The FRAM architecture offers advantages over traditional flash for frequent write operations. Consider the 16 MHz processing speed and available I/O lines against application complexity requirements.

Microcontrollers Part Context

This component belongs to the MSP430FR59xx series of ultra-low-power mixed-signal microcontrollers. It shares core architectural similarities with other variants in the family but is distinguished by its specific memory size and package type. The FRAM technology differentiates it from older flash-based MSP430 devices.

Microcontrollers Replacement Considerations

MSP430FR5994IPMR: Same functional specifications but in an LQFP-64 package. MSP430FR5994IPNR: Same functional specifications but in an HTSSOP-44 package. Verify pinout compatibility and physical dimensions before substitution.
