One-Time-Programmable memory cells based on Poly fuses simplify trimming of analog and digital parameters
Unterpremstaetten, Austria -- June 12, 2008 -- austriamicrosystems’ Full Service Foundry business unit announced today at the DAC, Design Automation and Conference in Anaheim, CA, a further expansion of its IP block portfolio with the launch of a complete set of OTP (one-time-programmable) cells for its 0.35ìm process family. Easy and economical trimming of analog and digital parameters, such as bandgap trimming, biasing, storage of serial numbers, temperature correction or unique configuration codes, makes them the ideal solution in ADCs, DC/DC converters, LDOs, lighting and power management products and many more. “Offering an easy to use and reliable field programmable memory solution without the need for additional masks enables our customers to design highly competitive products," says Thomas Riener, General Manager Full Service Foundry at austriamicrosystems. "The OTP blocks allow storing of analog and digital parameters, such as bandgap trimming, biasing, storage of serial numbers, temperature correction or unique configuration codes without wasting silicon area."
The polyfuse-based OTP memory cell “PPROM” is available in two fixed sizes of 4x8 bit and 16x8 bit and comes with a parallel interface. It is accessible like a static RAM and offers direct addressed outputs. The “PPTRIM” blocks available in sizes of 8 bit, 16 bit, 32 bit, 48 bit and 64 bit offers a three wire interface and auto-load at poweron reset. Both types of blocks are infield programmable at 3.3V operating voltage, data retention is guaranteed for at least 10 years. All OTP blocks are fully automotive and medical qualified and are available for austriamicrosystems advanced 0.35ìm CMOS, High-Voltage CMOS and SiGe-BiCMOS technologies. The siliconproven OTP blocks can be obtained from austriamicrosystems based on a one-time license fee. Customers will receive the simulation model (Verilog format), abstract (LEF format) as well as the timing library in TLF format. The OTP blocks can be easily integrated into the product design using the HIT-Kit, austriamicrosystems’ well known process design kit.
