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。

Flash memory interface chip select input pin.

IRCSB

Negative Input the "H" level during non-access and the "L" level during access.

Setting the IRON pin to "H" enables input.

Flash memory interface serial clock input pin.

Setting the IRON pin to "H" enables input.

Flash memory interface serial data output pin.

Setting the IRON pin to "H" enables output.

Flash memory interface serial data input pin.

Setting the IRON pin to "H" enables input.

IRSCK

IRSO

IRSI

Hi-Z^*2

Pin to enable the flash memory interface.

When this bit is set to "L", the flash memory interface pin is disabled. A

pull-down resistor is internally connected to the LSI.

Positive Set this bit to "L" during playback operation using flash memory.

Setting this bit to "H" allows rewriting of the flash memory using the

flash memory interface.

IRON

Set this bit to "H" for onboard rewriting.

*1 Initial value at reset input and power-down. The pin whose IO is "I" indicates a fixed level from outside.

*2 IRON pin "L" setting status
