RENESAS M65851FP

M65851FP
Single Chip Karaoke Processor
REJ03F0172-0201
Rev.2.01
Jan 25, 2008
Description
The M65851FP is an LSI that not only contains circuits (echo and key control) necessary for Karaoke but also improves
other peripheral functions.
This IC has full peripheral functions including vocal cut, phase shifter, equalizer, detection of intervals between songs,
digital surround, and Karaoke scoring. It is therefore suitable not only for dedicated Karaoke units but also for radio
cassette tape recorders, TV, VCR, and miniature unit audio systems with Karaoke function.
Features
•
•
•
•
Capable of composing echo and key control circuits necessary for Karaoke system with a single chip
Echo circuit is capable of supporting digital surround by adopting 16 Kbit RAM built-in digital delay
17 steps of –8 to +8 for key control (1 step is equivalent to a half tone)
Karaoke entertainment functions such as Karaoke scoring, vocal cut, equalizer, phase shifter, detection of intervals
between songs, and magic voice functions
• Generation of unnecessary radiation is avoided because clock’s built-in current-control oscillation circuit keeps
clock effects inside the clock
• Built-in automatic reset circuit activated with power turned on
• 5 V single power supply
Recommended Operating Condition
• Supply voltage range: VCC = 4.5 to 5.5 V
• Rated supply voltage: VCC = 5 V

EQOUT
Bass block is resonance type which is used simulated inductor amplifier. Treble block is filter type. These can be set
–12 dB to +12 dB/2 dB step.
Following is a center frequency “fO”, “Q” (bass resonance block).
fO =

2π C1 • C2 • R1 • R2
(Hz)
Q = (C1 • R2) / (C2 • R1)
Vocal Cut Block
The sound components of the same phase and same sound volume in the L and R channels are attenuated.
This made also allows components with lower frequency than the vocal band to pass through the filter, to compensate

Scoring Function
Scoring function judge the MIC vocal input.
Scoring Output Form
MIC input is judged from 0 to 99 level.
Constitution
Scoring function is constituted following two ways.
Judgment Conditions
1. Compare the frequency
2. Vocal level judgment
Function
Compare the frequency reference voice and microphone voice
Ratio
75%
Vocal level judgment
(as vocal is bigger than reference level, judgment is good)
25%
Music Search
Music search is constituted following.
(1) Input signal reference level comparison
(2) Music detection
(3) No music detection
1. Input signal reference level comparison
Input signal reference level comparison is constituted amplifier and level comparison.
When input signal is bigger than reference level, level comparison output the pulse which added internal clock.

2. Music detection
To search a music interval, it is necessary to judge if it is a music or not. This judgment is made by monitoring the
20 seconds and counting the pulse signal (after level detection). The pulse signal counts is bigger than fixed counts,
it is judged as a music.
Pulse counter is reset whenever monitor 20 seconds or judged no music decision.

3. No music detection
After music decision “2. Music detection”, no music is judged when no pulse in level detection at 3 seconds. But if
there is not no pulse when monitoring the 3 seconds, no music decision counter is reset.

and, the gain of amplifier GV is
GV = R2/R1 = 20 dB.
Same as the band pass filter is constituted microphone signal input.
Automatic Vocal Support
In case using the Karaoke system, when microphone input level is nothing, then audio source vocal appears and help the
microphone songs.

Oscillation Circuit
This IC incorporates a current control type clock oscillator circuit in it, thus providing circuit configuration just by
connecting a R for current control pin 29 (CLKCNT).
Fully internal clock supply prevents occurrence of undesired radiation without affecting any external circuit.
The oscillator frequency fck is following.
fck = 8 MHz

This IC is automatically reset when the power is turned on, and is automatically canceled nearly 120 ms later.

1. Internal music detection decides the scoring output timing
When Karaoke song is over and then music detection judgment the no music detection, scoring is over and output
the “H” pulse to REQ.
After REQ is “H” level and then W/RSEL changes from “L” to “H”, this IC changes a output mode and it can
output the score result.

destruction or for the purpose of any other military use. When exporting the products or technology described herein, you should follow the applicable export control laws
and regulations, and procedures required by such laws and regulations.
4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this
document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document,
please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be
disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )
5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a
result of errors or omissions in the information included in this document.

of such information to the intended application. Renesas makes no representations, warranties or guaranties regarding the suitability of its products for any particular
application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing
applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all
damages arising out of such applications.

10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain
rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage
caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and
malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software
alone is very difficult, please evaluate the safety of the final products or system manufactured by you.
