SIMPLE MELODY GENERATOR

FEATURES

FT66T-xx

FUNCTIONS

 127-note ROM memory

 Solution of automatic stop or repeat of the melody

 Dynamic speaker can be driven with external

NPN transistor

 1.3V to 3.3V power supply and low power consumption

 RC oscillator on chip

 Two or three times repeat of melody (mask option)

 Each note can be individually programmed to be

staccato or legato (mask option)

 One shot or level hold mode

 Sound range: 4 octaves, 2 series

 Tempo: 16 kinds (presto-largo)

 Direct piezo drive

 Changing the contents of melody is possible by

reprogramming the maskable ROM

 Power on reset; melody begins from the first note

 Start from the head of melody

 Bare chip is available

DESCRIPTION

The FT66T is a CMOS LSI chip which electronically plays a prearranged melody. Selection of melody start signal is possible by

mask option: orders specification suffix "L" indicate Level Hold Mode, and suffix "S" indicate One Shot Mode.

The Universal version (as One Shot or Level Hold Mode) is possible also (suffix "U").
