Epson Licenses Sarnoff’s TakeCharge ESD Design IP For High-Voltage Driver ICs Used In LCD Panels


- Epson Expects 50% Smaller Chip I/O Areas, Faster Time-To-Market -


Sarnoff Europe ( and Seiko Epson Corporation ( today jointly announced that the Epson Semiconductor Operations Division has licensed Sarnoff Corporation’s TakeCharge(R) on-chip electrostatic discharge (ESD) design IP portfolio. Epson will use TakeCharge for its high-voltage CMOS (HV-CMOS) integrated circuits, which are used as drivers for liquid crystal display (LCD) panels.

Epson is the world market leader for LCD driver ICs. The company will use TakeCharge to achieve a 50% reduction in chip I/O area while maintaining robust ESD protection with the technology’s “first-time-right” design capabilities.

“By utilizing TakeCharge in designing the I/O area of our HV-CMOS devices, we will be able to offer new ICs with improved capabilities even faster than before,” said Yoshiyuki Miyayama, General Manager of the IC Design Technology Department in Epson’s Semiconductor Operations Division. “We expect to achieve a substantial reduction of the on-chip I/O area, and the first-time-right feature means we can reduce our costs by saving time in engineering, and eliminating the need for additional masks.”

According to Koen Verhaege, Senior Director of Sarnoff’s Integrated Circuit Systems & Services Business Unit and Executive Director of Sarnoff Europe, TakeCharge has been licensed to leading semiconductor companies in Japan and around the world.
“We are especially gratified that an industry leader such as Epson has chosen our technology for its HV-CMOS design projects,” said Verhaege. “High-voltage chips are a very promising field, and we believe TakeCharge can make a significant contribution there.”

TakeCharge(R) has been silicon proven in advanced processes down to 65nm CMOS including SOI. In addition to Epson, licensees include Toshiba, Sony, OKI, JRC, Hynix, Infineon, Altera, PMC-Sierra, Renesas, Ricoh, Matsushita, and Scintera.
