â‘ The language recording and playback circuit ISD1000A series is divided into ISD1012A (12s, 12s,
10.6kbps), ISD1016A (16s, 8.0 kbps), ISD1020A (20s, 6.4 kbps).
â‘¡ISD1000 series language circuit is essentially an analog data acquisition system, using DTAS (direct analog storage) technology, the recorded information can be directly recorded in the EEPROM inside the chip, so it can better retain the effective components in the language analog and reduce The sound quality is distorted, which improves the quality of recording and playback, and obtains natural and realistic sound reproduction.
â‘¢Because there is electricity on the chip, the EEPROM can be changed, so it can be recorded and played, rewritten or deleted arbitrarily, without the need for a special language curing development system for programming and burning. The number of repeated recordings is more than 10,000, and the recorded information can be stored for more than 10 years.
Information will not be lost after power failure.
â‘£It has the ability to store up to 160 information segments.
⑤Using dual-in-line 28-pin and quad-in-line 28-pin packages, single 5V power supply. 
Application circuit of ISD1000A series voice chip
S1, S2, and S3 are respectively the switch of chip selection, status control, and recording and playback status.
