MSM9800/9836 EVA Board
Voice ROM Evaluation Board for MSM9802/9803/9805/9836
1/15
GENERAL DESCRIPTION
The MSM9800/36 Evaluation Board is designed to evaluate sound data, created by using OKI's Sound Analysis
and Editing tool
(
AR762/203/204
)
, for use with MSM9802/MSM9803/MSM9805/MSM9836.
FEATURES
512 Kbit/1 Mbit/2 Mbit/4 Mbit EPROM can be used for evaluation.
Power Supply:
4.75 to 5.25V
Clock Oscillation:
4.096 MHz Ceramic Oscillation
The board is not functional with CR oscillation. Input to the XT/
CR pin is
disabled.
NOTE
Some operations may not be identical to those with an actual target device. Further description is given later in
this document after Page 9.

SETTING UP AND OPERATING THE BOARD
Power Supply and Power-On Switch
The following power supply options are available with the board. Be sure to select a right power supply option to
your environment before ordering.
On-board AC 100 V Power Unit
Hook up power cable from the unit to AC 100 V outlet. Push upward the switch on the unit to turn it ON, and
push downward to turn it OFF.
On-board AC 100 V to 240 V Power Unit
Hook up power cable from the unit to AC 100 to 240 V outlet. Push upward the on-board Power switch to turn
the board ON, and push downward to turn it OFF.
On-board Battery Box
Use 4
AAA batteries. Push upward the on-board Power switch to turn the board ON, and push downward to
turn it OFF.
Lower battery voltage may cause noise to be overlapped with voice. In that case, use new batteries.
External Power Source
Input +5 V to the on-board V
DD
pin and 0 V to the GND pin.
The board's LED indicator goes on when power is supplied properly to it, whichever power option you choose.

20-pin Connector
The connector provides an interface for an external MCU control.
You can input/output control signals via this 20-pin connector when you use an external MCU to control the
board. The following table describes the pin connections.

Note 1: 1-3 pins of this connector output +5 V. Short circuit with power supply circuit of the external
unit may cause damage of the power supply unit and/or the evaluation board.
(
The
connector's 1 - 3 pins should be cut and isolated, as required.
)
Note 2: Every input pin is either pulled-up or pulled-down with a resistor. Be aware that not every pin
function identically to those on your target device, MSM9802/03/05/36.

Evaluation ROM Socket
Use this socket to mount an EPROM containing sound data for evaluation. When using a 512 Kbit EPROM,
place the chip so that the pin 14 is inserted to the socket's pin 16 position, as shown in the figure below.
Use EPROM Size Selector Switches to select a proper EPROM size.
EPROM Size Selector Switches
The following table shows the selector switch position for each EPROM size.
