A 0.9V/1.2V I/O Library in TSMC 55LP.
This SoundWire Digital I/O Library in TSMC 55nm LP offers an advanced, low-power interface solution for high-performance audio applications. Supporting 0.9V/1.2V operation, this library provides Data, Clock, and Select I/Os, enabling seamless integration with SoundWire-based systems while delivering enhanced power efficiency. This next-generation library intro duces auto delay calibration, improving timing precision and signal integrity beyond previous versions. Built for reliability, the I/O cells meet 2kV HBM, 500V CDM, and 8kV system-level ESD protection (150pF, 330 direct contact to housing), with 18kV air discharge capability, ensuring robust protection against electrostatic and environmental stress. Ideal for low-power, high-fidelity audio designs, this I/O library provides superior performance with enhanced calibration and compliance with industry standards.
