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 2-1/2 2-3/4 3 3-1/4 3-1/2 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.
