一、简介

九齐ny3pThe voice chip replacement solution is made in ChinaKT148A性价比更高420秒长度

九齐ny3pThe voice chip is from Taiwan Jiuqi Company2013The classic voice chip launched in 2009,还是采用的4Bit machine architecture,It is also the most familiar formula and the most familiar taste of Taiwanese chip manufacturers

As soon as the chip is released,Basically, it occupies a large market share of voice chips,Really good performance,The cost is also low enough,Especially for toy guns,toy cars, etc,非常的稳定

But stand this year2022year's perspective,Nine Qi'sny3pIt's no longer the best,Domestic voice chips have also grown rapidly,Basically everyone can see it online,and can find somesop8封装的语音ic,They are also based on the secondary development or self-packaged chips of Jiuqi or Shuocheng

Their cost is actually quite low,But how to operate、推广、售前、After-sale costs remain high,So lead to the actual chip,to the final product

价格并不亲民,basic100seconds or more chips,reach nearly2元的成本,A little more voice,成本就更高了

此时KT148A的优势凸显出来了,The core advantages are as follows

1. Products with high seconds,有成本优势,单价1.5,不分版本,不分型号
2. KT148A芯片采用aDSP+flashstack packaging,Solved the difficulty of proofing,Proofing is expensive,The user can repeat the replacement of the sound by himself

2.1 九齐ny3p的简介

NY3PxxxJOTPSeries products are single-chipCMOS语音合成IC,It is Jiuqi Technology for supportNY3ANY3BNY3CNY3D系列MaskROMThe product is specially developed embedded typeEPROM架构的OTPIC(OneTime Programmable),共有7The mothers are respectivelyNY3P005J、NY3P010JNY3P016JNY3P035JNY3P065JNY3P087J和NY3P115J.最多有5个/O脚(NY3P005J&NY3P010J只有3个//O脚),Use precise internal resistance to oscillate(+/-0.5%),Therefore, there is only one set of oscillating resistors that do not need to be addedPWM输出,Therefore, no additional parts are required.Speech synthesis method and NY3ANY3BNY3CNY3D系列MaskROM产品相同,藉由OTPReplaced during burningCode资料,You can write different voice data by yourselfEPROM中.User can use simple Q-Speech和Quick-10tool software for rapid development,然后使用Q-Writer软件搭配OTPWriterThe hardware comes very fastOTP烧录.

二、九齐ny3p的IC功能

(1).宽广的工作电压:18V~5.5V

(2).共有7个母体,对应不同NY3series capacity(Hex-16进制)和秒数(@6kHz

 

2.2 KT148AIntroduction to the chip

KT148A是一款32位的DSP语音芯片,标准的SOP8封装.内置420KByte的语音空间,最大支持420秒的语音长度,支持多段语音,同时支持直驱0.5W的扬声器,支持用户自己更换语音,目前该芯片的优势如下：

1、性价比高,相比较传统的OTP芯片,Technological improvements have reduced costs,同时芯片可重复烧录

2、用户可以自行的更换声音,通过电脑端的串口即可自己完成,无需其他昂贵的工具

3、芯片自带足够的空间,可以追求更高的音质效果

1. 32 位 DSP 语音芯片、5MHZ的内部振荡,PLL到120MHZ;

2. 工作电压 2.0~5.5V; 注意低于3.3V的供电,硬件上有细节的区别

3. 待机功耗小于 25ua;另有低功耗模式1.5uA

4. 16bit 的 PWM输出、可直接驱动 8欧姆 /0.5W 喇叭;

5. 提供工具自行转换音频格式,全部用户可以自己操作,非常简单

6. 16KHZ 下最大可以支持200秒.8KHZ 下最大可以支持400秒

7. 客户可以通过电脑端的工具软件,通过串口直接更换语音内容

8. 支持一线串口控制,当然可以根据需求订制各种协议

9. 支持 224 段地址,有更多需求可以扩展;

10.具有硬件 iic接口、UART 接口,可以为客户定制各类功能.

11.芯片具备重复烧录的能力,所以任何时候不用担心测试不完整,导致批量性的问题

 Complete development information,The data package is as shown above,Very complete and detailed

Pad No	Pad Name	ATTR	Description 描述
1	GND	Power	电源负极
2	PB9	I/O	Busy信号=播放输出低空闲输出高 复用串口下载,连接MCU或者USB转TTL的RX脚
3	PB1	I/O	[ONELINE-DATA]一线串口输入端 复用串口下载,连接MCU或者USB转TTL的TX脚
4	PB0	I/O	KEY按键--测试IO--对地触发就播放
5	SPK1	Out	不分正负,支持8欧姆0.5W
6	SPK2	Out	不分正负,支持8欧姆0.5W
7	VDDIO	Power	芯片内部的LDO输出,最大100mA
8	VBAT	Power	电源正极

1、供电的注意事项：

(1)、建议给芯片的供电,做到5V供电,电压越高芯片驱动喇叭的功率也越高,声音也越大

(2)、如果是[3.3--4.2V]锂电池的场景,电源正极直接进芯片的8脚即可

(3)、如果是干电池的供电场景,电源正极也是直接进芯片的8脚

(4)、如果需要超低电压供电,如2V--3V之间的纽扣电池,建议芯片的7脚和8脚直接短路,再连接电源正极

2、快速测试说明：

==》芯片的是第4脚为测试脚,外接一个按键或者镊子对地触发一下,就会播放下一个语音

==》连接好扬声器,然后供电之后,就可以用第4脚对地测试了
