High-Voltage CMOS Process Includes Flash

Austriamicrosystems high-voltage CMOS process with embedded Flash is rated for 50 V. The Flash process technology is a modular extension of austriamicrosystems’ 0.35-μm CMOS process. Full compatibility to the base process allows re-use of IP Blocks and the addition of Flash memory on a single chip. The process is suited for harsh environments, making it ideal for designs in power management, automotive or medical applications.

The products for many applications will benefit from excellent reliability over an extended temperature range by using a proven PMOS-based NVM technology. Endurance will be at least 100,000 cycles at 125°C while data retention is ensured for a minimum of 20 years at 125°C. A robust cell concept enables optional configuration as Flash or EEPROM memory without any process changes. Supply voltage ranges from 2.2 V to 3.6 V for read and 2.7 V to 3.6 V for write.

The process is based on the 0.35-μm CMOS process transferred from TSMC. It 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 3.3-V, 5-V, 20-V, 50-V and 120-V devices on a single chip.
