Hi,
According to the data manual in Table 4-27(Power Supply Signal Descriptions),
DESCRIPTION of VPP is "leave unconnected".
However, VPP is connected to the VPP1V8 in schematic of EVMK2G(www.tij.co.jp/.../EVMK2G).
Which is correct?
If VPP needs to be connected, there is no description for VPP in data manual "5.4 Recommended Operating Conditions."
What is Recommended Operating Conditions? (1.71～1.89V?)
Also, VPP2 is only valid for high-security (66AK2G1xS) devices.
Although EVMK2G(www.tij.co.jp/.../EVMK2G) is not high-security (66AK2G1xS) devices,
VPP2 is connected to the VPP1V8 in the schematic .
Which is correct (whether the pin should be connected or not)?
Thanks.
