Recommended Operating Conditions
(AVss
= Vss = 0 V)
*1 : The operating power supply voltage differs depending on the instruction cycle time of the operating frequency.
See Figure 1.
*2 : The operating power supply voltage differs depending on the instruction cycle time of the operating frequency.
See Figure 2. Note also that on the MB89PV550A the input to the VCC1 pin is cut off internally, and on the
MB89P558A the VCC1 pin is used as the VPP pin for on-board writing.
*3 : AVcc and VCC2 should be set to the same potential. Also, care must be taken to ensure that VCC1 does not exceed
VCC2.
*4 : Care must be taken to ensure that the relation between AVR and DVR is such that “VCC1
≤ AVR (DVR) ≤ AVCC
+ 0.3 V”.
