Recording chip ISD1700 series is a highly integrated, high-performance chips.
It can be multi-segment recording, the sampling rate can be adjusted from 4K to 12K, the power supply can range from 2.4V to 5.5V. ISD1700 there was the new recording prompts, when a new recording after, LED back flash once every few seconds to alert users to new recordings.
In addition, there are four kinds of sound to prompt the user's operating results, such as start recording, stop recording, erase, erase all the next one and so on. Recording data is stored in the FLASH chip, without any compression, so there are better sound quality and power storage.
Chip has two independent audio signal input channel, microphone input, and analog signal inputs. In independent key mode, when the operation is completed, a functional chip will automatically enter power-down mode to reduce power consumption.
In SPI mode, the user can do more functions on the chip operation. If for any memory address for playback on the analog channel configuration register (Analog Path Configuration register, APC) for reading and writing.
Specification:
Power supply: 5V; Refer images(last) for operating manual.
Recording time: 6K at 75 seconds, 8K for 60 seconds;
Chip operating frequency 6KHZ and 8KHZ optional;
with power indicator light, the chip indicator lights;
Simple operation, no microcontroller or other modules needed, will be able to work directly; chip control pin is already leads to facilitate the control connection
