We present TexCAC, the world's first direct-textileattachable, NVM-based MCU for the command and control of advanced smart textiles. Fabricated in 22 nm, it occupies merely$4.8 ~\text{mm}^{2}$while integrating 2 MB MRAM-offering a$4 \times \sim \mathbf{1 1 4} \times$increase in NVM capacity over state-of-the-art designs of comparable or larger area. Measured fully on-textile, TexCAC achieves an optimal active energy of$18 \text{pJ}$cycle at 0.52 V, rivaling the efficiency of leading MCU implementations.
