ymu759b ma-2 mobile audio 2 yamaha corporation ymu759 catalog catalog no.:lsi-4mu759b2 2001.5 outline ymu759b is a synthesis lsi for portable telephone that is capable of playing high quality music by utilizing fm synthesizer and adpcm decorder that are included in this device. as a synthesis, ymu759b is equipped with yamaha?s original fm synthesizer, with which the device is capable of simultaneously generating up to 16 voices with different tones. since the device is capable of generating adpcm data simultaneously synchronous with the play of the fm synthesizer, various sampled voices can be used as sound effects. since the play data of ymu759b are interpreted at anytime through fifo, the length of the data (playing period) is not limited, so the device can flexibly support applications such as incoming call melody distribution service. the hardware sequencer built in this device allows playing of complex music without giving excessive load to the cpu of the portable telephones. moreover, the registers of the fm synthesizer can be operated directly for real time sound generation, allowing, for example, utilization of various sound effects when using the game software installed in the portable telephone. ymu759b includes a speaker amplifier with low ripple whose maximum output is 550 mw (spvdd=3.6v). the device is also equipped with conventional functions including a vibrator and a circuit for controlling leds synchronous with music. for the headphone, it is provided with a stereophonic analog output terminal. for the purpose of enabling ymu759b to demonstrate its full capabilities, yamaha proposes to use ?smaf: synthetic music mobile application format? as a data distribution format that is compatible with multimedia. since the smaf takes a structure that sets importance on the synchronization between sound and images, various contents can be written into it including incoming call melody with words that can be used for training karaoke, and commercial channel that combines texts, images and sounds, and others. the hardware sequencer of ymu759b directly interprets and plays blocks relevant to systhesis (playing music and reproducing adpcm with fm synthesizer) that are included in the data distributed in smaf. features fm synthesizer functions tones fm synthesizer is capable of creating countless tones theoretically. when synthesizing tones, it is necessary to designate the number of operators to be used for the synthesis. increasing the number of operators allows synthesis of tones that are more intricate and closer to those generated by natural musical instruments. ymu759b supports synthesis of tones of two types including 2-operator tones and 4-operator tones. because operator's wave shape can be chosen from eight kinds, the quality of s ound improves more remarkably than 2 operator sound of the ma-1 series. (a ma-1 series can choose operator wave shape from two kinds.)
ymu759b -2- number of voices simultaneously generated ymu759b is equipped with 32 operators. the number of voices simultaneously generated varies depending on how many 2-operator tones and 4-operator tones are used. when only 2-operator tones are used: up to 16 voices can be generated simultaneously. when only 4-operator tones are used: up to 8 voices can be generated simultaneously. compatible with stereophonic sound generation. volume control channel volume, master volume, expression, and pan pot control in individual channels sequencer is built in. can interpret mobile multimedia format directly. equipped with four systems of 96 fifos for sequence data supports direct access that directly controls fm synthesizer. supports key control with half an octave higher and lower. adpcm reproduction function equipped with adpcm decoder with 4 bits, 1 channel supports two kinds of sampling frequency, 4 khz and 8 khz. sequencer is built in. equipped with 348 byte fifo for adpcm data and 32 byte fifo for sequence data supports direct access that directly controls adpcm section. speaker amplifier and equalizer circuit output of speaker amplifier: 550 mw when spvdd=3.6 v, or 400 mw when spvdd=3.0 v balanced input speaker amplifier provides low ripple built-in equalizer circuit corrects the difference of frequency response among the speakers and forms of bodies. interface 4 wire serial interface or 12 wire parallel interface can be selected. others pll is built-in to support master clock input in 2 mhz to 20 mhz range. provided with a circuit for controlling on/off of leds and vibrator. these can be operated synchronous with the play data. provided with a stereophonic analog output terminal for headphone 16 bit stereophonic d/a converter is built in. supports power down mode. (typical current: 1 a or less) power supply voltage the power supply includes two power supply sub-systems, analog power supply devoted to speaker amplifier and power supply for other sections. the power supply for the speaker amplifier (spvdd) supplies voltages in the range 2.7 v ~ 4.5 v (typ 3.6 v), and other power supplies (vdd) voltages in the range 2.7 v ~ 3.3 v (typ 3.0 v). 32-pin plastic qfn.

(*1): read wait time varies in the register which accesses it. (*2): max 70ns is the delay time when it is outputted from the d5 terminal. delay time from the sdout terminal varies according to pull-up resistance value and the load capacity of the outside. standard delay time can be calculated by step response expression of the rc circuit. time to change to the voltage of [power supply of external pull-up resistance 80 % ] is as follows. 1 - exp ( -t / r c ) = 0.80 when r = 1k ? , c= 50pf, t = 80ns // "standard delay time" and the reason why it was written are because resistance value and capacity value swing by the part's own error and the temperature character.
