It can access up to 10 different messages of variable length stored in external EPROM or ROM chips. Message activation is simplified since each message has its own trigger pin . If memory bank switching technique is used, the number of messages supported can be easily expanded to 20, 40 or more. APPLICATIONS n Multiple message playback n Sound effects generator VP-1410A (DIP48) Pin Assignment m o .c U 4 t e e h S a t a .D w w w http://www.eletech.com The VP-1410A is totally self-contained. It can access the external memory all by itself without the help from any microprocessor. Although the chip provides only 16 address lines, an external counter can be easily added to extend the memory addressing to virtuely no limitation. Therefore very long message length can be achieved easily. O...
