 ISD1810 Single-Chip, Single-Message Voice Record/Playback Device 8- to 16-Second Durations Advance Information.

ISD1806B是一顆支持4-10秒的錄放音語音芯片,支持4-8K的聲音采樣率,通過振蕩電阻來進行秒數的調節,振蕩電阻腳位為ROSC Pin,以實現用戶的功能所需...

下面是振蕩電阻所對應的錄放秒數和時間列表

采樣率	8 kHz	6.4 kHz	5.3 kHz	4 kHz
ROSC	80K	100K	120K	160K
時長	4.7 secs	6.0 secs	7.5 secs	9.4 secs

 

產品優勢：

1, ISD錄放音IC有掉電保存功能,在更改電池后,聲音還是保存在芯片內部．

2, 工作電壓2.4V—5.5V；輸出方式：PWM＆DAC . 環-芯

3, 簡單易用的錄放功能,僅支持單段錄放音操作.

4, 成熟的市場產品,在錄放音領域占有絕大部分的市場份額.

5, 100年的信息保存時間,華邦Winbond品牌.

FEATURES • Easy-to-use single-chip, single-message voice record/playback solution • High-quality, natural voice/audio reproduction • Push-button interface – Playback can be edge- or levelactivated • Variable record/playback duration controlled by external resistor selection which sets sample rate. 8 KHz sample rate = 8 seconds 6.4 KHz sample rate = 10 seconds 5.3 KHz sample rate = 12 seconds 4.0 KHz sample rate = 16 seconds • Automatic power-down mode – Enters standby mode immediately following a record or playback cycle – 0.5 µA standby current (typical) • On-chip 8
speaker driver • Zero-power message storage – Eliminates battery backup circuits • 100-year message retention (typical) • 10,000 record cycles (typical) • On-chip oscillator • No algorithm development required • Single +3 volt power supply • Available in die form and 28-pin 600 mil DIP (for sampling only)

Information Storage Devices’ ISD1810 ChipCorder? provides high-quality, single-chip, single-message, record/playback solution with user-selectable durations of 8 to 16 seconds. The CMOS devices include an on-chip oscillator (with external control), microphone preamplifA@Cier, automatic gain control, anti-aliasing filter, multilevel storage array, smoothing filter, and speaker amplifier. A minimum record/playback subsystem can be configured with a microphone, a speaker, several passive components, two push-buttons, and a power source.
