s HANDLING DEVICES
1.
Preventing Latchup
Latchup may occur on CMOS ICs if voltage higher than VCC or lower than VSS is applied to input or output pins
other than the medium-and high-voltage pins or if voltage higher than the rating is applied between VCC and VSS.
When latchup occurs, power supply current increases rapidly and might thermally damage elements. When
using, take great care not to exceed the absolute maximum ratings.
Also, take care to prevent the analog input from exceeding the digital power supply (VCC) when the analog system
power supply is turned on and off.
To supply power, turn on the digital power supply (VCC) and then the analog power supply (AVCC).
2.
Treatment of Unused Input Pins
Leaving unused input teminals open may lead to permanent damage due to malfunction and latchup; pull up or
pull down the terminals through the resistors of 2 k
or more.
Make the unused I/O terminal in a state of output and leave it open and if it is in an input state, handle it with
the same procedure as the input terminals.
3.
Treatment of N.C. Pins
Any pins marked “NC” (not connected) must be left open.
4.
Power Supply Voltage Fluctuations
Although Vcc power supply voltage is assured to operate within the rated range, a rapid fluctuation of the voltage
could cause malfunctions even if it occurs within the rated range. Stabilizing voltage supplied to the IC is therefore
important.As stabilization guidelines, it is recommended to control power so that VCC ripple fluctuations (P-P
value) will be less than 10% of the standard VCC value at the commercial frequency (50 to 60 Hz) and the transient
fluctuation rate will be less than 0.1 V/ms.
5.
Treatment of power supply pin
All VSS power suppluy pin must be use at the same voltage level.
Connect to be AVCC
= VCC, AVSS = VSS even if the A/D converters are not in use in MB89PV210.
6.
Notes on Using External Clock
When an external clock is used, oscillation stabilization time is required for even power-on reset and release
from stop mode.
7.
Notes on using the CR (internal) oscillator
To use the CR (internal) oscillator as the operating clock for the MB89215, MB89F217 or MB89P215, adjust the
timer value and baud rate setting.
8.
Program Execution in RAM
When the MB89PV210 is used with an emulation pod other than the MB2144-508, no program can be executed
in RAM.
9.
Operation check for evaluating the LIN-UART
When the MB89215, MB89F217 or MB89P215 uses the CR (internal) oscillator as the clock for the LIN-UART,
the evaluation program (MB89PV210 [customized for external oscillation]) requires an operation check within a
range of oscillation frequencies from 8.5 MHz to 11.5 MHz.
