Power-on and power-off sequence of A/D converter and analog input
Turn on the A/D converters (AV
CC
, AVRH) and analog inputs (AN0 to AN19) after turning on the digital power
supply (V
CC
) .
During power-off, turn off the digital power supply (V
CC
) after turning off the A/D converters and analog inputs
(AN0 to AN19) .
In this case, make sure that AVRH does not exceed AV
CC
during the power-on/power-off procedure.
Also make sure that the input voltage does not exceed AV
CC
when a pin which is also used as an analog input
is used as an input port.
Handling power supply pins on A/D converter-mounted models
Make sure to achieve "AV
CC
=
AVRH
=
V
CC
" and "AV
SS
=
V
SS
" in connecting the circuits, even when not using the
A/D converter function.
Note on power-up
To prevent the internal regulator from malfunctioning, maintain the voltage rise time at 50
μ
s (between 0.2V and
2.7V) or more during power-up.
10. Stabilization of power supply
8.
9.
Even when the V
CC
power supply voltage is within the specified operating range, it may still cause the device to
malfunction, if the power supply changes rapidly. For stabilization reference, it is recommended to control the
supply voltage so that V
CC
ripple variations (P-P values) at commercial frequencies (50/60 Hz) fall below 10
%
of the standard V
CC
supply voltage and the coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous
power switching.
11. Writing to Flash memory
For serial writing to Flash memory, always make sure that the operating voltage V
CC
is between 3.13V and 3.6V.
For normal writing to Flash memory, always make sure that the operating voltage V
CC
is between 3.0V and 3.6V.
12. P90/CS0 pins
P90/CS0 pins output “L” during writing Flash serial. Do not input from external.
13. Note of MB90F883 (S) , MB90F884 (S)
Maximum operating frequency is 25 MHz.
The base timer cannot use P24/TIO0, P25/TIO1, P26/TIO2, and P27/TIO3 as input function.
MB90F883(S) and MB90F884(S) do not contain the flash security feature and write-protect feature.
