MB90820 Series
17
Turn-off the digital power after turning off the A/D converter and D/A converter supply and analog inputs. In this
case, make sure that the voltage of AVR does not exceed AVCC (turning on/off the analog and digital power
supplies simultaneously is acceptable).
7.
Connection of unused pins of A/D converter and D/A converter
When the A/D converter and D/A converter are not used, connect the pins as follows: AVCC = VCC, AVSS =
AVR = VSS.
8.
N.C. pin
The N.C. (internally connected) pin must be opened for use.
9.
Notes on energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at
50
s or more.
10. Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers
turning on the power again.
11. Return from standby state
If the power supply voltage goes below the standby RAM holding voltage in the standby state, the device may
fail to return from the standby state. In this case, reset the device via the external reset pin to return to the normal
state.
