Descriptions: ISD1700 Voice Recording Module
ISD1700 voice module is fast be familiar with and master ISD1700 series chip and the design of a simple practical circuit board. It is suitable for ISD1700 full series chips, with simple operation, function complete etc. ISD1700 series recording chip is a kind of high integration, high performance chip. It can be multiple recording, sampling rate can be in 4 k to 12 k transfer among festival, power supply range can be in 2.4 V to 5.5 V between. ISD1700 and have new recording hint function, when a new recording, LED back to every few seconds flash a to prompt the user a new recording. In addition there are 4 sound to prompt the user’s operation results, such as start recording, stop the recording, erase, the next song and all erasure, etc. The recording data storage in the chips in the FLASH, without any compression, so have a good quality and power outages storage. Chip have two road independent speech signal input channel, microphone input and analog signal input. In the independent key mode, when a certain function operation after completion of the chip will automatically enter power down mode to reduce power consumption. In the SPI mode, users can to chips for more multi-purpose operation. As for any memory address for recording, Analog channel configuration register (Analog Path Configuration register, APC) such as reading and writing.

- 1. Recording REC:
Press and hold the REC button, the LED will light up at the same time, then speak into the MIC, the content of speech will be recorded into the ISD1700 voice chip.
After recording after a period raised the key LED will go off at the same time, press it again to start recording the second paragraph, the paragraphs were operating.

(2) level trigger: Play All chip will often press the PLAY button all the voice messages, and the cycle until you release the button.
- 3. Fast forward FWD:
Perform playback operations press this button, the playback pointer will point to the next section, double-click the point to this paragraph after the second paragraph of the starting point. During playback Press this key to stop playback of the current segment and then play the next paragraph, currently playing the last paragraph, stop playing the player in the last paragraph of the first paragraph.
- 4. Erase erase:
Single-segment erases operation only on the first and last paragraph, when the playback pointer in the first or the last paragraph, pressing this key will erase the first or last paragraph. Playback pointer will jump before the second or erase the penultimate paragraph. Often chip press this button more than 3 seconds to enter erase all modes of operation, the LED lights flash twice, continue pressing this button, LED 7 flashes turns off, release the button, the voice chip All erased.
- 5. Reset RESET:
Click this button chip perform a reset operation. Reset, play and record pointer points to the last paragraph of the playback pointer to the last paragraph of the Start the recording pointer to the last paragraph of the last. Perform playback to play the last paragraph, perform recording and then start recording a new last paragraph in the last paragraph.
- 6. Tuning VOL:
Click this button can adjust the size of the chip output sound. Chip the default output for maximum sound, every click sound 4dB attenuation. Until the minimum of sound, continue press this button, click, the sound increases 4db (Note: you perform a reset, the sound output).
- 7. FT passthrough operations:
FT pin with GND, continued to maintain a low level will start passthrough mode. Straight-through the operation will voice from Analn end direct access to speakers or AUD output. During recording, press the FT, will also record an incoming voice Analog signal.
