This macro-cell is an ultra-low power, general purpose 32.768kHz internal oscillator core aimed for RTC (real time clock) applications.
A 6-bit digital bus allows frequency adjustment against process variations. It has self-biased, built-in references and doesn’t require external ones. The core is easily retargeted to any other CMOS technology due to its MOSFET-only oscillator architecture.
