ISD1810 Datasheet, PDF (2/18 Pages) Winbond – Single-Chip, Single-Message Voice Record/Playback Device 8- to 16-Second Durations

ISD1810 Product
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 level-
activated
• 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 fol-
lowing a record or playback cycle
– 0.5 µA standby current (typical)
• On-chip 8 9 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)
