High-rel EEPROM IP blocks designed to withstand temperature up to 170 Deg C

austriamicrosystems has expanded its EEPROM IP block portfolio for its 0.35µm process family includes 14 non-volatile memories (EEPROM and/or Flash) starting with small blocks offering 20x8 bit and 64x8 bit memory size, ideally used for trimming purposes ranging to larger size memories with up to 12,5kx32 bit size used for program and/or firmware storage. Austriamicrosystems says furthermore customer specific memories may be generated on demand.

All high reliability and high temperature EEPROM blocks are fully automotive-qualified making them suitable for harsh environment in applications such as automotive, medical and industrial applications withstanding temperature up to 170 Deg c while operating. Austriamicrosystems says its NVMs very robust against daylight and ultra-violet radiation preventing any unintended erase of stored content.

Optimized for low power and low voltage applications, the endurance of high reliability and high temperature memories is rated at 1 million read/write cycles at 25°C and at least 100k cycles at 125°C while data retention is ensured for a minimum of 20 years at 125°C. Supply voltage ranges from 1.2V to 3.6V for read and write complete the key technology features of the new EEPROM blocks.

"With an endurance of more than 1 million read/write cycles at 25°C and ensured data retention for a minimum of 20 years at 125°C, austriamicrosystems sets a benchmark in ultra high reliability EEPROM blocks. In combination with an extended temperature range up to 170°C, these blocks are ideally suited for applications in the automotive and industry fields or harsh environments", said Thomas Riener, Senior Vice President and General Manager of austriamicrosystems' Full Service Foundry business unit. "Available as part of our recently launched "More than Silicon" initiative, this EEPROM IP portfolio expansion provides foundry customers a competitive advantage for their products and demonstrates austriamicrosystems capabilities as a leading specialty analog foundry."

These immediately available IP blocks can be integrated to the chip designs using austriamicrosystems' process design kit called HIT-Kit. Due to the modularity of the processes foundry customers can re-use 100 percent of their standard 0.35µm CMOS designs, while the memory block is added right before starting production of the wafer, says austriamicrosystems.
