16 logic cells: too few for density figures, which are given for projects of 1,000 or more.

Every figure here is measured from the public layout, the same way for every design on the chip: see data and method, and how its designs used the process.

Process features

Which parts of the GF180MCU process this design uses: its transistor voltages and where they come from, its gate oxides, and any devices drawn by hand outside the standard cells, SRAM and pads.

3.3 V44 custom transistors
5 V7t-5V standard cells
Gate oxidesThin (3.3 V) and thick (5 V/6 V) in the design itself

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.
