The 14-channel 10-bit ADC covers analog monitoring (thermistors, current shunts, potentiometers) without an external mux, and the peripheral set includes I²C, SPI, UART, LIN, and IrDA, so a single MCU handles sensor bus, actuator interface, and diagnostic link. MSL 3 out of the bag — bake before reflow if the moisture barrier bag has been open past the floor-life window.","metaTitle":"TI MSP430FR5721IRHAT 16-bit MCU, 8 MHz, 4 KB FRAM, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5721IRHAT 16-bit MCU with 8 MHz core, 4 KB FRAM, 1 KB RAM, 14x10-bit ADC, I²C/SPI/UART/LIN.

The MSP430FR5721IRHAT offers the same 8 MHz core and peripheral set but with 4 KB FRAM versus 2 KB on the '5720. Pin-compatible in the same 40-VQFN package, so a BOM swap is straightforward if the extra memory is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5721IRHAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5721IRHAT when reusing this data.
