TECHNICAL DATA

BT8028-XX

SIMPLE MELODY GENERATOR

FEATURES

FUNCTIONS

• 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

• 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

SS VCC OUT

• Start from the head of melody

• Bare chip or TO-92 are available

DESCRIPTION

The BT8028 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").
