Questions answered in Guangzhou维创 manuals
What control modes are supported by the WTV series voice chips?
The chips support key control, key‑combination control, parallel (port) control, one‑wire, two‑wire, and three‑wire serial control modes.
How does the BUSY pin indicate playback status?
During voice playback the BUSY pin can be set to output either a high or low level, allowing it to be used as a playback‑status indicator.
What is the minimum external component count for a basic ISD1420 system?
A minimal system needs one microphone, one speaker, two buttons, a power source, and a few resistors and capacitors.
How long can recorded information be retained in the ISD1420?
Recorded information can be stored for up to 100 years and replayed up to 100 000 times.
