XC2788X
XC2000 Family Derivatives / Premium Line
Electrical Parameters
1) The short-term frequency deviation refers to a timeframe of a few hours and is measured relative to the current
frequency at the beginning of the respective timeframe. This parameter is useful to determine a time span for
re-triggering a LIN synchronization.
2) This parameter is tested for the fastest and the slowest selection. The medium selections are not subject to
production test - verified by design/characterization
3) f_WU in MHz
4) This value includes a hysteresis of approximately 50 mV for rising voltage.
5) V_LV = selected PVC/SWD voltage level
6) The limit V_LV - 0.10 V is valid for the OK1 level. The limit for the OK2 level is V_LV - 0.15 V.
Conditions for t_SPO Timing Measurement
The time required for the transition from Power-On to Base mode is called t_SPO. It is
measured under the following conditions:
Precondition: The pad supply is valid, i.e. V_DDPB is above 3.0 V and remains above 3.0 V
even though the XC2788X is starting up. See also V_DDPB requirements in Table 13.
Start condition: Power-on reset is removed (PORST = 1).
End condition: External pin toggle caused by first user instruction executed from FLASH
after startup.
Conditions for t_SSB Timing Measurement
The time required for the transition from Standby to Base mode is called t_SSB. It is
measured under the following conditions:
Precondition: The Standby mode has been entered using the procedure defined in the
Programmer’s Guide.
Start condition: Pin toggle on ESR pin triggering the startup sequence.
End condition: External pin toggle caused by first user instruction executed from FLASH
after startup.
Conditions for t_SSO Timing Measurement
The time required for the transition from Stopover to Stopover Waked-Up mode is
called t_SSO. It is measured under the following conditions:
Precondition: The Stopover mode has been entered using the procedure defined in the
Programmer’s Guide.
Start condition: Pin toggle on ESR pin triggering the startup sequence.
End condition: External pin toggle caused by first user instruction executed from PSRAM
after startup.
