EASE1000 V2 User’s Manual
2.5 Target System Requirements
The target system connected with EASE1000 V2 must meet the following requirements.
Target System requirements
Item Description
Interface connector Must support the EASE1000 V2 interface cable
Must have a 14-pin 2.54 mm pitch connector
(Compatible connector: HIF3FC-14PA-2.54DSA)
Target LSI
Positive power supply (V
DD
)
voltage
1.6 to 5.5V (Note 1)
Power consumption (VTref) 10mA
■Note 1■
- Since the target LSI positive power supply is used for the internal circuit of EASE1000 V2, its power
consumption increases when EASE1000 V2 is in use.
Use an appropriate amount of the target system positive power supply while considering the power
consumed by EASE1000 V2.
- Do not connect EASE1000 V2 when measure the consumption current of a target system.
The on-chip debugging circuit in target LSI influences, and consumption current increases.
The following shows the power consumption of the VTref pin used inside EASE1000 V2.
