Preliminary Technical Data
TIMING SPECIFICATIONS
AC inputs during testing are driven at V
Logic 1 and V
For timing purposes, a port pin is no longer floating when a 100 mV change from load voltage occurs. A port pin begins to float when a
100 mV change from the loaded V

ADE7129F16 internal PLL locks onto a multiple (512 times) of the 32.768 kHz external crystal frequency to provide a stable 12.58 MHz internal clock for the system. The
core can operate at this frequency or at a binary submultiple called Core_Clk, selected via the PLLCON SFR.
