DESCRIPTION:
The ES502 demonstration board illustrates the signal routing and flexibility of the ISD5008 as well as its recording and playback functions. The unit comprises an ISD5008, an ISD2560 to simulate background conversation, a Winbond W78E51 microcontroller, microphone and attendant circuitry, a seven-segment display for displaying mode and level information, and a keypad for selecting the modes. In addition, there are Power, Record, Pause and Play pushbuttons. The most prominent feature of the system is an LED map of the available signal paths (indicated by red LEDs) which indicates the path in use for each of the demonstration modes. The map also shows which sections of the device are powered for each function with orange LEDs and the selected volume level with yellow LEDs in a bar graph.1 DEVICE SUPPORTED: Product supported ISD5008 Series CONTENTS OF KIT: − − − One ISD-ES502 Demo Board Two AA batteries Instruction Sheet( User’s guide with Schematics) Ordering Code ISD-ES502
INITIAL SETUP: 1. 2. 3. When the ISD-ES502 board is initially received install the batteries, carefully observing polarity. If some of the LEDs light at this time, push the green Power Button to start unit properly. Otherwise, push the green Power Button on the lower left to power on the unit. The ES502 will announce that it is "Ready" and conclude with the "-" in the middle of the numeric LED display turned on. Note t.
