2 Electrical Specification
2.1 Maximum Ratings
The maximum ratings are the limit values that must never be exceeded even for an instant. As long as the
device is used within the maximum ratings specified range, it will never be damaged.
The Cx71 series of CMOS ASICs has five types of output buffers for driving current values, each of which
has a different maximum output current rating.

2.1.1 Power-on sequence
Lavender and Jasmine are dual power supply devices. For power ON/OFF sequence, there is no specific
restriction, but the following sequences are recommended:
Power-ON:VDDI (internal, 2.5V)-> VDDE (external, 3.3V)-> Signal
Power-OFF:Signal-> VDDE (external, 3.3V)-> VDDI (internal, 2.5V)
It is restricted that VDDE only is supplied continuously for more than 1 minute while VDDI/DRAM supply
is off. If the time exceeds 1 minute, it may affect the reliability of the internal transistors.
When VDDE is changed from off to on, the internal state of the circuit may not be maintained due to the
noise by power supply. Therefore, the circuit should be initialized after power is on.
