• Manufacturer Part Number: mb90f362tspmt
• Description: 16-bit Proprietary Microcontroller
• Manufacturer: Fujitsu Microelectronics, Inc.

Special care is required for the following when handling the device :
1. Preventing latch-up
2. Treatment of unused pins
3. Using external clock
HANDLING DEVICES
• Preventing latch-up
• Treatment of unused pins
• Using external clock
• Precautions for when not using a sub-clock signal
• Notes on during operation of PLL clock mode
• Power supply pins (V
• Pull-up/down resistors
• Crystal oscillator circuit
• Turning-on sequence of power supply to A/D converter and analog inputs
• Connection of unused pins of A/D converter
• Notes on energization
• Stabilization of power supply voltage
• Initialization
• Notes on using CAN Function
• Flash security function
• Correspondence with +105 °C or more
CMOS IC chips may suffer latch-up under the following conditions :
• A voltage higher than V
• A voltage higher than the rated voltage is applied between V
• The AV
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
Use meticulous care not to exceed the rating.
For the same reason, also be careful not to let the analog power-supply voltage (AV
power-supply voltage.
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the
device. Therefore, they must be pulled up or pulled down through resistors. In this case, those resistors should
be more than 2 kΩ .
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
To use external clock, drive the X0 pin and leave X1 pin open.
