The 4K x 8 RAM is modest — budget it carefully if your firmware uses deep interrupt nesting or large lookup tables. The internal oscillator trims to the 16 MHz clock without an external crystal, saving two pins and board area. ## Industrial temperature range and 24-DSBGA footprint The 24-DSBGA package (0.4 mm pitch typical) keeps the board footprint tiny — about 2.5 mm × 2.5 mm — but demands careful PCB layout and a controlled assembly process. Expect to use micro-vias and a solder-mask-defined pad; the datasheet's recommended land pattern is worth following exactly. ## Connectivity and analog — what's on the pins The 8-channel 10-bit ADC samples at rates adequate for slow analog signals like thermistors or potentiometers; don't plan on audio-rate acquisition. The IrDA and SCI connectivity options are legacy but still useful for IR remote control or LIN-bus gateways in automotive body electronics. The base product number MSP430FR2633 covers multiple package variants; the IYQWT suffix specifically identifies the 24-DSBGA tape-and-reel option.","metaTitle":"TI MSP430FR2633IYQWT 16-bit MCU, 16 MHz, 15.5 KB FRAM","metaDescription":"Texas Instruments MSP430FR2633IYQWT 16-bit MCU with 16 MHz core, 15.5 KB FRAM, 4K x 8 RAM, I²C/SPI/UART, 8x10b ADC, -40°C to 85°C.

For a completely different architecture, the C2000 F280041PZQR offers a 32-bit C28x core at 100 MHz with CAN and more analog channels, but it uses Flash memory and a larger package — not a pin-compatible drop-in."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2633IYQWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR2633IYQWT when reusing this data.
