Austriamicrosystems Expands Field-Programmable OTP Memory Portfolio

Austriamicrosystems’ has launched a set of OTP (one-time-programmable) cells for its 0.35µm process family. Easy and economical trimming of analog and digital parameters, such as bandgap trimming, biasing, storage of serial numbers, temperature correction or configuration codes, the solution in ADCs, DC/DC converters, LDOs, lighting and power management products and many more. 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 power-on 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 0.35µm CMOS, High-Voltage CMOS and SiGe-BiCMOS technologies. The silicon-proven 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 integrated into the product design using the HIT-Kit.
