H66T19/32/68 Series
Description
The H66T19/32/68 series is a CMOS LSI designed for use in door bell,
telephone and toy applications. It is an on-chip ROM program-med for
music performance. Produced by COMS technology, the device results in
very low power consumption. Since the H66T19/32-/68 series includes
oscillation circuits, a compact melody module can be constructed with only
a few additional components.

Functional Description
Oscillator Circuit
The oscillation frequency is used for tone and beat generators. Its accuracy affects the quality of the
music.
Tone Generator
Tone frequencies are oscillator frequencies-M, where M is any even number from 64 to 256. Within a
melody 14 scales can be selected including PAUSE code and END code. The tone generator is a
programmed divider. The range of scales is from "C4" to "C6" and that for freq-uency varies from
258Hz to 23768Hz.
Rhythm Generator
The rhythm generator is also a programmed divider. It contains 15 available rhythms as follows:
1/4
1/2
3/4
1
1-1/4
1-1/2
1-3/4
2
2-1/4

3-3/4
J. Four rhythms can be selected from these.
Melody Rom
The Mask ROM can memorize 64 notes with 6 bits. 4 bits are used for controlling the scale co-de and
2 bits are used for controlling the rhythm code.
Tempo Generator
There are 15 available tempos in the H66T19/32/68 Series. The 15 tempos are: 128, 137, 148, 160,
175, 192, 213, 240, 274, 320, 480, 640, 960, 1920 J / minute.
