A 1.8 V LDO with ±2% accuracy holds the rail inside the spec across load steps. The 1.71 V minimum is the brown-out threshold — the internal POR and brown-out detect reset the core cleanly if the rail dips below that level. ## 100-HTQFP with exposed pad — thermal and footprint notes The package is a 100-HTQFP (14x14 mm) with an exposed thermal pad. ## Connectivity and peripherals for automotive control The 54 general-purpose I/O pins provide enough headroom for a motor-drive design with encoder feedback, hall sensors, and auxiliary relay outputs.","metaTitle":"TMS320F28066PZPQ C2000 C28x Piccolo MCU, 90MHz, AEC-Q100","metaDescription":"Texas Instruments TMS320F28066PZPQ 32-bit C28x MCU, 90MHz, 256KB Flash, 34Kx16 RAM, -40 to 125°C, AEC-Q100 automotive.

It typically offers more Flash and RAM, and a higher core clock speed. The TMS320F28066PZPQ is the 90 MHz, 256 KB Flash, 34K x 16 RAM member. Both share the same 100-HTQFP package and pinout, so a board designed for the F28066 can accept the F28069 with a firmware update, but the BOM cost differs. Check the specific datasheet for exact parametric deltas."},{"question":"Can TMS320F28066PZPQ be used as a replacement for TMS320F28065?","answer":"The TMS320F28065 is a lower-density sibling in the same family. The F28066 offers more Flash (256 KB vs typically 128 KB) and more RAM. Both use the same 100-HTQFP package and are pin-compatible, so a drop-in replacement is possible if the firmware fits within the F28065's memory. If the existing code exceeds the F28065's capacity, the F28066 is a natural upgrade path."},{"question":"Is TMS320F28066PZPQ RoHS compliant?","answer":"The part is listed with a standard commercial RoHS compliance status, consistent with Texas Instruments' C2000 series. The 100-HTQFP package is lead-free compatible. Verify the specific date-code compliance certificate if required for your destination market."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TMS320F28066PZPQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TMS320F28066PZPQ when reusing this data.
