With other ordinary ISD4004/4003 module compared to, voice recording NewWay the module Rec-1000 has the following advantages:
1. Onboard a 51 MCU, which has been burning the voice recording program, a key playback functions, of course, more complex functions can be achieved, a full set of data sent microcontroller programming and 51 has not any distinction, simple development can be done directly with it.
2. Extraction onboard microcontroller two control pins, you can then direct external control signal is applied to control the on-board microcontroller, two interface or microcontroller RS232 interface (TTL level), you can also be sent in an external serial instruction control onboard microcontroller, the data provide a full set of drivers for your convenience.
3 If you do not want to use the on-board microcontroller friends, we have to elicit ISD4004/4003 voice chip all the control interface, and make a clear and accurate labeling, easy to control ISD4004/4003 directly to the use of other external microcontroller.
4 on-board microphone, direct recording.
5. Onboard the LM386 amplifier system, sufficient to meet the ordinary needs.
We designed two speaker interface, easy on different occasions with different speakers cascade.
7. Onboard audio input interface, in line with our send your recordings lines, able to take the sound directly from a computer or other playback device can achieve high-quality recordings.
8 onboard audio output interface, can be directly connected to the system and an external amplifier or headphones, to achieve high-quality playback
9. Onboard the 3V power conversion module, convenient and 5V systems cascade.
10. Onboard MINI-USB interface, used to take power, so you do not have to find that the power supply will be able to develop in front of a computer.
11 onboard power outlets, enables you to take power in the practical application of convenient, safe and reliable.
12 onboard two buttons, all connected with the microcontroller, and facilitate the development and application.
13. Onboard switch and power indicator, status indicators, and facilitate the development and application of.
14 onboard volume adjustment knob to adjust the output volume needed.
15 and we will send you the module schematics, MSP430 programs, 51 programs, allowing you to quickly grasp ISD series programming and development of the chip. Select ISD4004 reason:
a Built-in microcontroller serial communication interface
b 3V single-supply operation, low power consumption
c multistage information processing
d operating current of 25-30mA, maintain current 1μA
e consumable information is saved 100 years (typical)
f high-quality, natural voice reduction technology
g 10 million times the recording cycle (typical value)
h automatic squelch function
i free to adjust the clock chip, optional external clock
