Function
Product quality may suffer if the absolute maximum rating is exceeded even
momentarily for any parameter. That is, the absolute maximum ratings are rated
values at which the product is on the verge of suffering physical damage, and
therefore the product must be used under conditions that ensure that the absolute
maximum ratings are not exceeded. The ratings and conditions indicated for DC
characteristics and AC characteristics represent the quality assurance range
during normal operation.
The oscillation frequency shown above indicates only oscillator characteristics.
Use the V850ES/JJ3 so that the internal operation conditions do not exceed the
ratings shown in AC Characteristics and DC Characteristics.
Time required to set up the flash memory. Secure the setup time using the OSTS
register.
When using the main clock oscillator, wire as follows in the area enclosed by the
broken lines in the above figure to avoid an adverse effect from wiring
capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating
• Always make the ground point of the oscillator capacitor the same potential as
• Do not ground the capacitor to a ground pattern through which a high current
• Do not fetch signals from the oscillator.
When the main clock is stopped and the device is operating on the subclock, wait
until the oscillation stabilization time has been secured by the program before
switching back to the main clock.
For the resonator selection and oscillator constant, customers are requested to
either evaluate the oscillation themselves or apply to the resonator manufacturer
for evaluation.
The oscillation frequency shown above indicates only oscillator characteristics.
Use the V850ES/JJ3 so that the internal operation conditions do not exceed the
ratings shown in AC Characteristics and DC Characteristics.
