Are there any requirements when powering up HX2VL?
I would like to know if there are any conditions such as ramp rate or monotonic increase required.
Thanks,
Tetsuo

Hi,
The conditions are mentioned in the H2VL datasheet. The internal reset is released 2.7 µs± 1.2% (max) after supply reaches power good voltage (2.5 V to 2.8 V). The reset time applied in external reset circuit should be longer than that of the internal reset time (~ 3 us).
Once the clock is ready and CPU has clock, HX2VL initializes the firmware (FW) within 50mS.

Mallika-san,
Are there any regulations for the startup waveform of VCC?
For example, ramp rate, monotonically increasing, etc...
Thanks,

Hi,
There are no restrictions. Please check the datasheet.
