PRODUCT INFORMATION

N588D is a voice chip with a single -chip kernel. Therefore, it can be named N588D series voice single -chip microcontroller. The N588D series voice single -chip machine is a editable voice chip that integrates the single -chip microcomputers and voice circuits jointly developed by Guangzhou Jiuxin Electronic Technology Co., Ltd. and Taiwan Huabang. Our company guarantees that the performance of the product is exactly the same. N588D can be rubbed multiple times, industrial -level performance, there are many triggers such as serial port buttons and ports. There are upper machine software. Users can edit their voice and download, and completely fool -style operating voice chips.


The function of the N588D series of voice single -chip microcomputers is stable, and the wide -sounding range is stable, which makes up for the narrow defects of various types of voice chips in the past. The serial control mode and the expansion output mode of the three -line serial control control port are allowed to allow the application to put the product into the place where it can be almost imagined.


2. Product characteristics

Module packaging (with SPI-FLASH and peripheral circuits) has DIP16, DIP28, chip packaging includes DIP18, SSOP20, and LQFP32;

According to the differences between plug-in or built-in SPI-FLASH, the playback time is also different. Support 2M to 32Mbit SPI-FLASH memory;

Embedded DSP high -speed audio processor, fast processing speed;

 built -in 13bit/da converter, and 12bit/PWM output, good sound quality;

PWM output can directly push 0.5W/8 & omega; speakers to push the current with abundant current;

 Support the two output methods of DAC/PWM;

Support loading WAV audio format;

Support loading 6K ~ 22kHz sampling rate audio;

Support the audition of voice playback that has been loaded;

You can operate software through a professional upper machine, and you can compose the voice at will. You can insert mute. The mute you inserted does not occupy the capacity of the memory. One has been loaded to multiple addresses to multiple addresses;

220 paragraphs can control the address bit, a single address position can load 128 paragraphs of voice, and the voice combination in the address position is played;

Most of the voice that can be loaded for editing;

USB download method, support online download/off-machine download; even if the N588D voice chip is powered on, it can be downloaded normally to SPI-FLASH;

chip reset time 5ms;


Support MP3 control mode, key control mode, 3 & times; 8 button combination control mode, and mouth control mode, first -line serial control mode, third -line serial control mode, and three -line serial control port expansion output mode;

Switching of the third -line serial control mode to the expansion output mode of the control port of the three -line serial port control port can be switched. After switching, you can still bring the front and last working status of switching into the mode of switching after switching;

arbitrarily set the busy output method of displaying the state signal of the voice playback;

strong anti -interference, can be applied in the industrial field;

220 paragraphs can control the address bit, a single address position can load 128 paragraphs of voice, and the voice combination in the address position is played;

The voice playback stops to enter the dormant mode immediately, and the chip turns into a complete state;

15 keys control mode, any key can set any control mode;

supporting N588D VoiceChip upper machine software, the interface is simple and convenient to use. It can greatly play the functions of the N588D voice single -chip microcomputer;

Simple single -chip machine writing method, get rid of the complicated complicated compilation thinking in the past;

A single chip supports multiple memory of plug -ins;

The mute time range inserted is 10ms ~ 25min;

working voltage DC2.8V ~ 5.5V;

Static dormant current is less than 10UA;

Support 8 chord MIDI playback (this function needs to be opened).


 

3. Control mode

3.1, MP3 control mode

The N588D voice single -chip machine automatically defaults to the function of the 6 control ports, the corresponding list is as follows:

Control portP00P01P02P03P04P05
Functionstopplay / Pausenext trackprevious pieceVOL+VOL-


3.2, key control mode

There are 15 triggers such as non-circulating, previous song can be circulated, the next song can be circulated, volume+, volume-, play/stop, stop, play/stop, and can use 10 keys to trigger the control output;

3.3, 3 & Times; 8 button combination control mode

3 & times; all keys in the combination mode of the 8 keys are default as a pulse that can be repeatedly triggered, which can directly trigger 24 -paragraph voice, and each button triggered the voice address can be defined.

3.4, and mouth control mode

The advantage of the mouth mode is that the control speed will be faster, but it will also occupy more control ports. There are currently only N588D-32L voice chips, NW-28P voice module support and mouth control mode. P00 is defined as the SBT trigger foot, and the playback voice is triggered by changing the address position an. The definition of the foot position in the mouth mode is shown in the table below.


3.5, first -line serial control mode

Send serial data through a data cable. The first -line serial port can realize functions such as controlling voice playback, stopping, volume adjustment, and direct triggering voice. The keys of P00 ~ P10 can choose to block or arbitrarily trigger. In the first -line serial port control mode, the chip is unsustering, and the current is about 5mA after the voice is stopped. Please use it carefully when the battery is power supply. (See the timing of 9CH data at 9CH, see the figure below :)

3.6. Third -line serial control mode

The three -line serial port control mode consists of three communication lines, namely the chip selection CS, the data data, and the clock CLK. The timing is based on the standard SPI communication method. Three -line serial ports can be used to control and play for voice chip commands and voice playback. In the three -line serial port mode, all keys are invalid.

3.6.1, three -line serial control control port expansion output mode

Under the three -line serial port control mode, sending data F5H can enter the three -line serial port expansion output mode. In this mode, sending binary data can allow the relevant control port to output high levels to control peripheral circuits. Send the data F6H again, and exit the control port extension data mode and enter the conventional three -line serial control mode.
