Logic density and I/O — what 6864 cells and 114 pins mean for a BOM line
The LCMXO2-7000HC-6TG144I packs 6864 logic cells (858 LABs/CLBs) and 114 user I/O, with 245760 bits of block RAM on-chip — enough to absorb a medium-complexity state machine, a bridge between two voltage domains, or a sensor aggregation hub without an external SRAM. The 114 I/O count in a 144-TQFP means every pin on the package is an I/O except the power and ground — no wasted pins, but the fan-out on a two-layer board gets tight; a four-layer stack-up with a solid ground plane under the QFP keeps signal integrity clean at the internal 10-20 MHz toggle rates these cells typically run.
Package — 144-TQFP, field-swappable without a BGA station
144-TQFP (20x20 mm body, 0.5 mm pitch) — a standard QFP that a hot-air rework station handles in under two minutes. No underfill, no X-ray inspection, no BGA reball. The orientation is unambiguous: pin 1 chamfer on the top-left corner, and the package outline is symmetric enough that a mis-rotation is obvious before solder. Tray packaging — not tape-and-reel, so it ships in the same antistatic tray the pick-and-place feeder expects. No reel-to-tray transfer needed for hand assembly or prototype runs.
Active lifecycle and compliance — still a current-design part
Product status is Active — Lattice still manufactures and supports this order code. ROHS3 compliant (lead-free, no exemptions).
