AVM3324C
㆒般規格:
AVM3324C 乃㆒單晶片 3 頻道的音色合成器。(1個語音頻道單獨放音；或 2個音樂頻道放音；或 2
個音樂頻道 + 1個語音頻道聯合放音。) 此晶片有 4K 個指令格，且以 LOGPCM 編碼方式，合成長達
3秒之語音。藉由製造過程㆗更換光罩，將客戶需要之語音資料編寫入 ROM ㆗。
特性：
1. 單㆒工作電壓範圍為 2.4 ~ 6 伏特。
2. 聲音輸出組合如㆘：
A> 純語音：所有 D/A 的電流輸出全被語音使用。
B> ㆔個頻道隨意組合放音時：每個音樂頻道各佔㆕分之㆒ D/A 的電流輸出，語音頻道佔㆓分之㆒
D/A 的電流輸出。
3. 語音總長度可達 3.0 秒，且可被分割成 32 個語音段(voice_section)。
4. 其㆗每㆒語音段的長度 (語音 + 靜音) 最多可達 5.4 秒 (在 6KHz 取樣頻率㆘)。
5. ㆒個具有 4096 個指令格的 ROM，可被分割為 32 個指令組。在合成過程㆗，音色、節奏、音
調、播放速度、拍差、語音段、甚至 STS 輸出狀態，都可在指令組的任何位置編輯修改。音色是
由指定的 8 x 8 波形 及 32 x 32 包封架構合成而成。總共有 4 個音色，可被彈性㆞指定到第㆒或
第㆓音樂頻道。

GENERAL DESCRIPTION：
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 .

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.

Rev 1.2

AVM3324C
□ Parallel CPU_trigger: in this mode, could access sub_table 1-32. Some mask option must set as follow:
MATRIX/ALONE-->ALONE, SEQUENTIAL/NORMAL --> NORMAL, RESET/UNRESET-->RESET,
DEBOUNCE -->short
& for all the playing type:
EDGE/LEVEL --> EDGE, HOLD/UNHOLD -->UNHOLD, RETRIGGER/IRRETRIGGER-->RETRIGGER
In this mode, ROW1-4 & COL1 are used as (sub_table binary adress-1) input (sub_table1--32). COL4 is used as low
active enable input.
STS1, STS2, STS3 must have one selected as busy low or busy high for CPU interface strobe.
7. A8 or M16 could be mask_selected as NORMAL, SEQUENTIAL:
□ NORMAL: normal subtable mode as in item 6.
□ SEQUENTIAL:
A> if the input was triggered sequentially the device will response by one subtable by one subtable of voice_step
sequentially and cyclically, form subtable_1 to user defined subtable_n(n:1--32).
B> The relationship between SEQUENTIAL(A8/M16) and other inputs (A1-A7/M1-M15) could be mask_selected as
RESET or UNRESET:
◎ RESET : once the other inputs were triggered the SEQUENTIAL sequence will reset to subtable 1.
◎ UNRESET : sequential sequence and other inputs are independent.
8. Three status output (STS1, STS2, MODE/STS3) have following mask options:
□ STS1:
□ STS2:
a>stop high_pulse
b>stop low_pulse
c>busy high_active
d>both melody ch1 & ch2 on
at first 1/4 or 1/8 beat
e>programmable
0>disable
1>led6 Hz or racing lamp
2>led3 Hz or racing lamp
3>voice dynamic 2/4
4>melody ch1 on at first 1/4 or 1/8 beat
5>melody ch2 on at first 1/4 or 1/8 beat
6>busy low_active
□ STS3:
a>stop high_pulse
b>stop low_pulse
c>busy high_active
d>busy low_active
e>pragrommable
0>disable
1>led 6Hz or racing lamp
2>led 3Hz or racing lamp
3>voice dynamic 2/4
4>melody ch1 on at first 1/4 or 1/8 beat
5>melody ch2 on at first 1/4 or 1/8 beat
6>both melody ch1 & ch2 on
at first 1/4 or 1/8 beat
a>stop high_pulse
b>stop low_pulse
c>busy high_active
d>busy low_active
e>led 6Hz or racing lamp
f>led 3Hz
g>voice dynamic 2/4
i>melody ch1 on at first 1/4 or 1/8 beat
j>melody ch2 on at first1/4 or 1/8 beat
k>both melody ch1 & ch2 on
at first 1/4 or 1/8 beat
If both STS1 and STS2 are in 6Hz or 3Hz mode, they will flash alternatively, STS3 will flash synchronously with STS1.
Dynamic means LED will flash depending on voice signal.
For each sub-table, the STS1, STS2, STS3 could be programmed within subtable as active or inactive.
STS3 is enabled only when the MODE/STS3 is in STS3 option.
The pulse width of stop pulse: 15ms--45ms (40ms at playback speed 6KHz).
"e" item of STS1 and STS2 means the output status is controlled by program, and could be changed during synthesizing.
NOTE: The 3Hz and 6Hz depend on the ratio of current playback speed (5.3Hz to 16KHz).
the stop pulse width depend on the ratio of final playback speed.
9. The internal stop pulse feedback mask options are offered. STS1, STS2, STS3 could only feedback to one of input
pins (ROW 1-4, COL1-4). For one input could only have one output feedback to it.

NOTE : Rosc=300K ohm , T=ß 100 TRANSISTOR , R1=1K NEED ( ONLY WHEN WISH TO LOWER THE POWER CONSUMPTION).
SPK=8 ohm SPEAKER ( ALL ARE TYPICAL ).
When using Racing Lamp, please pay attention to the restrictions as following:
1). Can't use MODE (must set STS3).
2). If use voice in songs, please extend every voice length using mute length as long as possible.
3). When want to use Racing Lamp forward spin, can't use 6Hz flash at STS1&2&3 simultaneously.
When want to use Racing Lamp backward spin, can't use 3Hz flash at STS1&2 and 6Hz flash at STS3 simultaneously.
4). If use Racing Lamp, all STS LED can't flash simultaneously.
5). If need racing flash follow rhythm and all flash follow rhythm simultaneously, need not choose Racing Lamp mode.
Please use STS programming in song files.
