LONDON Chip design and foundry company austriamicrosystems is expanding its service foundry operation to include a 50V high-voltage CMOS process with embedded flash.
The company says this is the first such flash process offered by a foundry and that it is a modular extension of its 0.35 micron CMOS process. With complete compatibility to the base process, it allows re-use of IP blocks and adding flash memory to it on a single chip.
Austriamicrosystems (Unterpremstaetten, Austria) is targeting the technology at makers of devices for power management, automotive or medical applications as well as for MEMS controllers.
The process uses the company's PMOS-based NVM technology and will offer endurance of at least 100k cycles at 125 C, with data retention guaranteed for a minimum of 20 years at the same temperature.
The company says the HV-CMOS technology is the first purely CMOS based high-voltage process that matches BCD performance and chip sizes at much lower process complexity. It is based on the 0.35 micron process transferred from TSMC.
The process offers fully scalable high-voltage NMOS and PMOS devices, floating logic libraries as well as a best-in-class power-on resistance. The process allows the integration of 3.3V, 5V, 20V, 50V and 120V devices on a single chip.
