Logic cells per mm² in each 0.1 mm square of the project (counted in the square, scaled up to a mm²). Hatched outlines are SRAM macros; the red outline is the densest 0.1 mm square that avoids them (31k logic cells per mm²), found by sliding a 0.1 mm square over the project in 20 µm steps, so it can straddle the fixed squares and find more than any one of them. Squares at the edges are partial, so they read low.

Want your own design on a chip like this one?

Start with a tile: the next Tiny Tapeout GF180MCU chips take projects until 7 December 2026, for wafer.space Run 3. For a die of your own, wafer.space Run 3 takes orders until 9 December 2026.

Tiny Tapeout and wafer.space are independent companies that work together (announcement). Tiny Tapeout runs its own shuttles: it takes the projects, builds the die, and sells and supports the chips and boards. wafer.space has the dies manufactured on its GF180MCU runs, and these pages are wafer.space's measurements of them.
