Zilog went public in 1991, but was acquired in 1998 by Texas Pacific Group. Curtis Crawford replaced Dr. Sack and changed the company's direction towards 32-bit data communications processors. Bonds were sold against the company to fund the new developments, but after the Internet bubble burst in 2000 and the resultant reduction in customer demand for such products, Curtis Crawford was replaced by James (Jim) Thorburn, who reorganized the company under Chapter 11 bankruptcy in late 2001 and refocused it on the 8- and 16-bit microcontroller market.
