Info

MB9B500 Series C Pin As this series includes an internal regulator, always connect a bypass capacitor of approximately 4.7 µF to the C pin for use by the regulator. Device C VSS GND 4.7μF Mode pins (MD0, MD1) Connect the MD pin (MD0, MD1) directly to VCC or VSS pins. Design the printed circuit board such that the pull-up/down resistance stays low, as well as the distance between the mode pins and VCC pins or VSS pins is as short as possible and the connection impedance is low, when the pins are pulled-up/down such as for switching the pin level and rewriting the Flash memory data. It is because of preventing the device erroneously switching to test mode due to noise. Notes on power-on Turn power on/off in the following order or at the same time. If not using the A/D converter, connect AVCC =VCC and AVSS = VSS. Turning on : VCC USBVCC VCC AVCC AVRH Turning off : USBVCC VCC AVRH AVCC VCC Serial Communication There is a possibility to receive wrong data due to the noise or other causes on the serial communication. Therefore, design a printed circuit board so as to avoid noise. Consider the case of receiving wrong data due to noise, perform error detection such as by applying a checksum of data at the end. If an error is detected, restransmit the data. Differences in features among the products with different memory sizes and between FLASH products and MASK products The electric characteristics including power consumption, ESD, latch-up, noise characteristics, and oscillation characteristics among the products with different memory sizes and between FLASH products and MASK products are different because chip layout and memory structures are different. If you are switching to use a different product of the same series, please make sure to evaluate the electric characteristics. 50 DS706-00010-1v0-E
HANDLING MB9BF500 MB9B500 Series Handling when not using USB If it is not using USB of MB9BF500, be sure to connect USBVCC power-supply pin, UDP0, and UDM0 pin to GND. ・Example of when not using USB MB9BF500 USBVCC UDP0 UDM0 VSS GND Handling when not using Sub oscillation pin If it is not using X0A and X1A (sub oscillation) pins of MB9BF500, use it with X0A = GND : X1A = OPEN.
