AVM3324C
GENERAL DESCRIPTION
Rev 1.2 2002/11/6
4
：
The
AVM3324C
is single-chip 3 channel timbre generator that can synthesize (2 ch melody and/or 1 ch. voice). It is
designed by instruction-based synthesizing method. Total has 4k instruction steps. Total voice is up to 3 seconds using
APLUS
qualified coding algorithm(LOGPCM). Customer speech data will be edited and programmed into ROM by
changing one mask during the device fabrication.
FEATURES
：
1. Single power supply can operate from 2.4V through 6V.
2. With following audio output combination
.
A> voice only: all D/A are occupied by voice(VOICE MODE).
B> All 3 channel could play out with arbitrary combination; each melody channel occupy 1/4 of D/A, voice channel occupy
1/2 of D/A (SYMPHONY MODE)
3. The total voice duration is about 3 seconds could be partitioned up to 32 voice sections.
4. Voice+mute length could be up to 5.4 seconds (6KHz sampling rate)for each voice section.
5. One 4096 instruction steps table, could be partitioned up to 32 subtables.
With programmable instructions, Timbre, Tempo, pitch, playback speed, rhythm, voice section, even STS output status
can be programmable changed anywhere during synthesizing.
Timbre is synthesized from assigned 8*8 waveform and 32*32 envelope structure. Total has 4 timbres, could be assigned
to ch1&2 flexibly.
Melody pitch: --3to ++5 & rest node, include half node. Total has 53 tones.
Voice melody playback pitch : -6# to +4,include half node. Total has 20 tones .
Voice playback speed: 5.35 to 16k Hz. Total has 20 playback speeds.
Voice playback speed (Hz): 5.35 5.66 6.00 6.36 6.73 7.14 7.56 8.01 8.49 9.08 9.53 10.10 10.70 11.33 12.00 12.72 13.47 14.28 15.27 16.0
Voice playback pitch: -6# -7 1 1# 2 2# 3 4 4# 5 5# 6 6# 7 +1 +1# +2 +2# +3 +4
Melody Tempo: 82 88 95 103 112 123 137 154 176 205 246 beats/minute
Total has 11 different tempo.
Rhythm difference: 1/8 1/4 3/8 1/2 5/8 3/4 1 1-1/4 1-1/2 2 2-1/2 3 3-1/2 4 0 beat
Total has 15 different rhythm
6. 3 Mask option trigger type: MATRIX, ALONE, CPU trigger.
□
MATRIX:
◎
4×4matrix inputs: M1--M16(MODE=0 --> sub_table 1-16) (MODE=1 --> sub_table 17-32).
◎
Priority: Mn+1>Mn+2>Mn+3>Mn+4 (n=0>4>8>12).
◎
Debounce time: depend on current playback speed (5.3Hz to 16Hz), or trigger during standby
the dependent speed is 7.64k
long---4.2 ms to 12.5 ms
short---150us to 430 us
□
ALONE:
◎
8 alone inputs: A1--A8 (MODE=0-->sub_table 1-8) (MODE=1-->sub_table 9-16), with resistive type schmitt input
(270---1M) for CDS interface.
◎
Priority: A1>A2>A3>A4>A5>A6>A7>A8
◎
Debounce time: depend on current playback speed (5.3Hz to 16Hz), or trigger during standby.
the dependent speed is 7.6k.
long---4.2 ms to 12.5 ms
short---150 us to 430 us
In both mode, all the trigger inputs could be assigned as different playing_type with following options:
EDGEL/LEVEL, HOLD/UNHOLD, RETRIGGER/IRRETRIGGER.
