DESCRIPTION:
The I16-COB00 is used to demonstrate the voice quality of the ISD1600B ChipCorder series. This board
has an empty PDIP socket, so that the desired device can be installed. It can also serve as a prototype
board for your initial applications.
Product supported Ordering Code
ISD1610B/12B/16B/20B I16-COB00
CONTENTS OF THE KIT:
− I16-COB00 COB/Demo board
− User’s manual
HARDWARE CONNECTIONS:
• Connect a speaker and a power supply to the related terminals. Please ensure the polarity of the
power is correct to avoid any damages to the COB and/or the device.
• Speaker (SP)/AUD selection: Default setting is SP output. If AUD output is needed, remove the
connection from center pad to Sp+ (Sp-) pad and re-connect the center pad to AUD (Vcc),
respectively, per diagram below.
OPERATIONS:
In order to perform the recording and playback functions, just connect a speaker and a power supply to the
demo board. Please ensure the polarity of the power is correct for avoiding any damages to the demo
board.
To Record, simply press-and-hold the REC button and speak to the microphone. The LED stays on while
recording. Release Record button to stop recording.
To Playback the recorded message using PlayE, simply pressing PlayE button once will play the message
and it stops automatically when completed. During playback, pressing PlayE button again will halt the
playback operation.
To Playback the recorded message using PlayL, simply pressing-and-holding PlayL button will play the
message and it stops automatically when completed. During playback, releasing PlayL button will cease
the playback operation.
To demonstrate the voice quality and various durations, one can change the Rosc to the desired value with
respect to the sampling frequency, as shown in the datasheet.
