EEPROM blocks for program and firmware storage

Austriamicrosystems' Full Service Foundry business unit has announced a further expansion of its non-volatile memory portfolio for its 0.35um process range.

The entire EEPROM IP block portfolio now includes 14 non-volatile memories (EEPROM and/or Flash) starting with small blocks offering 20 x 8 bit and 64 x 8 bit memory size, ideally used for trimming purposes ranging to larger size memories with up to 12,5k x 32 bit size used for program and/or firmware storage.

All high-reliability and high-temperature EEPROM blocks are fully automotive-qualified and eminently suited for harsh environment, making them ideal for designs in automotive, medical and industrial applications.

Products such as power-metering systems, motor-control units and engine-management systems will benefit from an ultra-high reliability over an extended temperature range up to 170C by using a proven PMOS-based NVM technology.

The patented bit cell concept makes Austriamicrosystems' NVMs robust against daylight and ultra-violet radiation.

Especially when implemented in WLP packages or bare dies, an unintended erase of stored content is successfully prevented.

Optimised for low-power and low-voltage applications, the endurance of high-reliability and high-temperature memories is typically 1 million read/write cycles at 25C and at least 100,000 cycles at 125C, while data retention is ensured for a minimum of 20 years at 125C.

Supply voltage ranges from 1.2 to 3.6V for read and write complete the key technology features of the EEPROM blocks.

The integration into a product design is said to be quick and easy using the HIT-Kit, Austriamicrosystems' process design kit.

Due to the modularity of the processes, foundry customers can reuse 100 per cent of their standard 0.35um CMOS designs, while the memory block is added right before starting production of the wafer.
