BT8028C-004

TECHNICAL DATA 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 (prestolargo) • Direct piezo drive FUNCTIONS • 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 or TO-92 are available BT8028-XX BT8028CXXL(S) V SS V CC OUT 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").
