Overview

This instruction manual is for the RB-D610Q306GD36 which is the reference board for ML610Q306 (hereinafter referred to as “MCU”).

This board can be combined with on-chip debug tool EASE1000 V2 and software development environment (DUT8 and MWU16) to do the following:

Development and debugging of the MCU control software.
Programming control and sound code data to the MCU internal Flash-ROM.
Voice playback by the MCU.

Operational notes

The following describes the precautions to follow when handling the RB- D610Q306GD36.

Turn off the power when inserting and removing jumper socket from PWR/SPVDD/VREF Jumper pin on the RBD610Q306GD36.
Turn off the power when attaching and reattaching external board, device and cable from CN1/CN2/CNUE Connector on the RB-D610Q306GD36.
Connect only monaural speakers to the jack.
RB-D610Q306GD36 is a device used only by experts in R&D facilities for research and development purposes. RBD610Q306GD36 is not intended to be used in mass-produced products or parts thereof.
The information in this document is subject to change without notice due to product improvement and technological improvement. Prior to use, please ensure that the information is up to date.
LAPIS Technology does not provide any RB-D610Q306GD36 support. Replace only in case of initial failure.

Specification

Jumper pin (PWR/SPVDD/VREF)
This board has three jumper pins named PWR/SPVDD/VREF. Each jumper pin specification is explained blow.

PWR jumper pin

PWR jumper pin can switch the supply source of VDD pin of MCU.

PWR	Contents
EASE	VDD pin is connected to 13pin of CNUE.
USR	VDD pin is connected to 4pin (UVDD) of CN1.

When attaching “EASE1000 V2” on the board, PWR jumper pin set to “EASE” if power supply from 13pin of CNUE
connector.
PWR jumper pin set to “USR” if power supply from CN1 connector.

SPVDD	Contents
VDD	SPVDD pin is connected to 2pin of PWR jumper pin.
USR	SPVDD pin is connected to 6pin (USPVDD) of CN1.

SPVDD jumper pin set to “VDD” if power supply from VDD as same as selecting PWR jumper pin.
SPVDD jumper pin set to “USR” if power supply from CN1 connector.

VREF jumper pin

VREF jumper pin can switch the supply source of VREF pin of MCU.

VREF	Contents
VDD	VREF pin is connected to 2pin of PWR jumper pin.
USR	VREF pin is connected to 24pin (UVREF) of CN2.

VREF jumper pin set to “VDD” if power supply from VDD as same as selecting PWR jumper pin.
VREF jumper pin set to “USR” if power supply from CN2 connector.
