It is designed by instruction-based synthesizing method. Total has 504 instruction steps. Total voice is up to 1.5 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 1.5 seconds could be partitioned up to 4 voice sections. 4. Voice+mute length could up to 2.7 seconds (6k sampling rate) for each voice section. 5. One 504 instruction steps table, could be partitioned up to 4 sub_tables in SEQUENTIAL mode. With programmable instructions, Tempo, pitch, playback speed, rhythm, voice section, even STS ON/OFF can be programmable changed anywhere during synthesizing. Melody pitch: --3 to ++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. Only one trigger TG1 is used as SEQUENTIAL mode with resistive type Schmitt input (270K--1M) for CDS interface. SEQUENTIAL: if the input was triggered sequentially, the device will response by one sub_table of voice step sequentially and cyclically, from sub_table 1 to user defined sub_table n (n=1 to 4). 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 this mode, TG1 could be assigned as different trigger type with following options: EDGEL/LEVEL, HOLD/UNHOLD, RETRIGGER/IRRETRIGGER. Because only 1 trigger, it has NO option RESET/UNRESET. So playing sequence will always be sub_table 1 to sub_table n and then feedback to sub_table 1 cyclically. 7. Only one status output (STS1) has following mask options: STS1: a>stop high_pulse b>stop low_pulse c>busy high_active d>busy low_active e>led 6Hz f>led 3Hz g>voice dynamic 2/4 h>melody ch1 on at first 1/4 or 1/8 beat, when pure voice, voice dynamic 2/4 i>melody ch2 on at first 1/4 or 1/8 beat, when pure voice, voice dynamic 2/4 j>both melody ch1 & ch2 on at first 1/4 or 1/8 beat, when pure voice, voice dynamic 2/4 3 Rev 1.2 2002/11/6 AVM1504D Dynamic means LED will flash depending on voice signal. For each sub-table, the STS1 could be programmed within sub_table as active or inactive. The pulse width of stop pulse: 15ms--45ms (40ms at playback speed 6KHz). NOTE: the 3Hz and 6Hz depend on the ratio of current playback speed (5.3Hz to 16KHz). the stop pulse width depends on the ratio of final playback speed. 8. The internal stop pulse feedback mask options are offered. 9. Snooze Function description: 1. Snooze Function use 2 sub_tables: 1st stores Ringing voice or melody (alarm sound), playing when time's up. 2nd stores [greeting sound +] snooze time. 2. Please refer to timing diagram 6.
