... Single-Chip, Single-Message Voice Record/Playback GENERAL DESCRIPTION Information Storage Devices’ ISD1810 ChipCorder provides high-quality, single-chip, single-message, record/playback solution with user-selectable du- rations seconds. The CMOS devices in- clude an on-chip oscillator (with external control), microphone preamplifier, automatic gain con- trol, anti-aliasing filter, multilevel storage array, smoothing filter, and speaker amplifier ...

... ISD1810 Product FEATURES • Easy-to-use single-chip, single-message voice record/playback solution • High-quality, natural voice/audio reproduction • P ush-button interface – P layback can be edge- or level- activated • Variable record/playback duration controlled by external resistor selection which sets sample rate. 8 KHz sample rate = 6.4 KHz sample rate = 5 ...

... The I S D1810 ChipCorder device is controlled by the RE C pin, and either of two playback pins (edge-activated playback), and (lev- el-activated playback). The ISD1810 parts are configured for design simplicity in a single-mes- sage application. Device operation is explained on “F unctional Description Example” on page 6. ...
