CDC706

SCAS829B – SEPTEMBER 2006 – REVISED FEBRUARY 2008...................................................................................................................................... www.ti.com

The CDC706 Power-Up-Circuit has an inbuilt hysteresis. If the voltage stays above VPUC_OFF, which is typically at

1.7 V, the register content stays unchanged. If the voltage drops below VPUC_OFF, the internal register is reloaded

by the ROM after VPUC_ON is crossed again. VPUC_ON is typically 2.1 V. Table 8 show the content of the ROM and

the Register after above voltage drops scenarios.
