SIMPLE MELODY GENERATOR
FEATURES
127-note ROM memory
1.3V to 3.3V power supply and low power consumption
RC oscillator on chip
One shot or level hold mode
Sound range: 4 octaves, 2 series
Tempo: 16 kinds (presto-largo)
Direct piezo drive
FUNCTIONS
FT66T-xx
Solution of automatic stop or repeat of the melody
Dynamic speaker can be driven with external
NPN transistor
Two or three times repeat of melody (mask option)
Each note can be individually programmed to be
staccato or legato (mask option)
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").
