描述
ML226xx系列是内置有4Mbit～32Mbit Flash存储器的语音合成LSI。由于内置了大容量存储器，因此非常适用于语音操作指导等需要长时间播放语音的应用。此外，该系列产品还支持通过微控制器改写Flash存储器。产品采用实现高音质的HQ-ADPCM、16位D/A转换器和低通滤波器，并内置用来直接驱动扬声器的1.0W单声道扬声器放大器。语音输出所需的功能已经全部集成于1枚芯片中，因此仅需增加本LSI，即可轻松实现语音功能。

Description

value ^*1

Reset input pin.

The LSI is initialized by the "L" level input. After a reset is input, all the

circuits stop operating and enter the power-down state.

At power-on, input an "L" level to this pin. After the power supply

voltage stabilizes, set this pin to an "H" level.

RESETB

(^*2)

A pull-up resistor is internally connected.

Input pin for testing.

TEST0

Positive A pull-down resistor is internally connected.

Fix to the DGND.

Status/error output pin 1.

Execute OUTSTAT command to select BUSYB^*3and NCR^*3in each

channel, or errors.

The initial value is BUSYB^*3of channel 0, and output data is "H" level.

Status/error output pin 2.

Execute OUTSTAT command to select BUSYB^*3and NCR^*3in each

STATUS2

channel, or errors.

The initial value is BUSYB^*3of channel 0, and output data is "H" level.

Command processing status signal output pin.

CBUSYB

N.C.

Negative An "L" level is output during command processing.

Be sure to input a command with this pin at an "H" level.

(^*2)

Unused pin.

Leave open.
