Mixed-Signal-ASICs

Complex application specific ICs optimized for price and performance can be achieved by integration of analog circuit components together with suitable I / O interfaces, digital signal and data processing. With additional integration of modern processor cores (including ARM) and various memory options (e.g. SRAM, OTP, EEPROM, Flash) an entire system on one chip (SOC) is possible. Further integration of sensors and actuators based on standardized semiconductor technologies provides our customers with a decisive competitive advantage.
