DESCRIPTION
■■■■
The MB90340-series with up to 2 FULL-CAN* interfaces and FLASH ROM is especially designed f or automotiv e
and industrial applications. Its main feature are the on-board CAN Interfaces, which conform to V2.0 Part A and
Part B, while supporting a very flexible message buffer scheme and so off ering more functions than a normal full
CAN approach. With the new 0.35 µm CMOS technology, Fujitsu now offers on-chip FLASH-ROM program
memory up to 512 Kbytes.
The power supply (3 V) is supplied to the internal MCU core from an internal regulator circuit. This creates a
major advantage in terms of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 42 ns instruction cycle time from an external
4 MHz clock.
The unit features an 8 channel Output Compare Unit and 8 channel Input Capture Unit with 2 separate 16-bit free
running timers. 4 UARTs constitute additional functionality for communication purposes.

Special care is required for the following when handling the device :
• Prev e nting 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
• Port0 to port3 output during Power-on

1. Preventing latch-up
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 VCC and VSS.
•The AV
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
For the same reason, also be careful not to let the analog power-supply v oltage (AV
power-supply voltage.
CC power supply is applied before the VCC voltage.
CC or lower than VSS is applied to an input or output pin.
:
CC, A VRH) e xceed the digital
2. Handling unused pins
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.
3. Using external clock
To use external clock, drive the X0 pin and leave X1 pin open.

4. Precautions for when not using a sub clock signal
If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin, and leave the
X1A pin open.
