X3100/X3101 – Preliminary Information
POWER-UP TIMING
Symbol
Parameter
t_PUR⁽⁶⁾ Power-up to SPI read operation (RDSTAT, EEREAD STAT)
t_PUW1⁽⁶⁾ Power-up to SPI write operation (WREN, WRDI, EEWRITE, WCFIG, SET IDL, WCNTR)
t_PUW2⁽⁶⁾ Power-up to SPI write operation (WCNTR - bits 10 and 11)
Min.
Max.
T_OC+2ms
T_OC+2ms
T_OV+200ms
or
T_UV+200ms⁽⁷⁾
Notes: (6) t_PUR, t_PUW1 and t_PUW2 are the delays required from the time V_CC is stable until a read or write can be initiated. These parameters
are not 100% tested.
(7) Whichever is longer.
