(14) Flash memory
- Erasing block unit size: 128 bytes
- Erasing / writing voltage range: 3.15V – 5.5V
- Maximum number of erase-write cycle: 50,000 times (Ta = +25°C) (with memory management program)
Note
The microcontroller will malfunction if the power supply voltage is less than the specified operable supply voltage. To
prevent a malfunction, the low voltage detect circuit should be connected externally, and the volta ge should always be set
to the proper level. If the power supply voltage becomes lower than the voltage which is detected by the low voltage detect
reset IC, then the m icrocont roller should be reset to restore stable opera tion. Use t he low volta ge detect re set IC which
detects the lowest specification voltage of the power supply.
We cannot ensure the integrity of the block data, if the microcontroller is reset while writing to the flash memory.
Therefore, in such a case, we recommend disabling any flash writing operation by user's program when the voltage
decreases to a level just above the voltage which is detected by the low voltage detect reset IC.

Recommended Oscillation Circuit and Characteristics
The oscillation circuit characteristics in the table below are based on the following conditions:
•
Recommended circuit parameters are verified by an oscillator ma nufacturer using a Sanyo provided oscillation evalua tion
board.
•
The characteristics are the results of the evaluation with the recommended circuit parameters connected externally.

(*) Note: The oscillation stabilizing time period is the time until the oscillation becomes stable after the VDD becomes higher
than the minimum operating voltage.
The oscillation circuit characteristics may differ by applications. For further assistance, please contact with the oscillator
manufacturer with the following notes in yo ur mind.
•
Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation
frequency on the production board.
Since the oscillation circuit characteristics are affected by the noise, wiring capacity, etc., refe r to the following notices.
•
The distance between the clock I/O terminal and external parts should be as short as possible.
•
The capacitors’ VSS should be allocated close to the microcontroller’s GND terminal and be away from other GND.
•
The signal lines with rapid state changes or the signal line with large amplitude such as middle withstand voltage port or LCD
driver output should be allocated away from the clock oscillation circuit.
•
The signal lines with large current should be allocated away from the oscillation circuit.
