July 30, 2013 -ON Semiconductor (Nasdaq: ONNN) , which promotes energy-efficient innovation, has launched a new device for MP3, with the miniaturization and reduced bill of materials (BOM) And there is a strong demand for recording and playback functions of portable MP3 audio applications to reduce costs. The LC823430TA audio processing system is a single-chip solution that integrates digital signal processing (DSP) circuits for MP3 encoding and decoding, as well as analog function modules, such as audio analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC).
The LC823430TA is available in a space-saving 128-pin TQFP package with a total height of only 1.2 mm. This new device contains a segmented driver circuit that can be connected to a liquid crystal display (LCD). There are two different versions, with 8 shared terminals x 18 segments (USB mode) or 4 shared terminals x 36 segments (non-USB mode) The display. The design of this device also embeds different flash memory interfaces, such as SD / MMC and USB2.0 device interfaces, to further save precious space and BOM.
In addition to MP3 encoding and decoding, the LC823430TA's embedded DSP also provides noise cancellation, which can eliminate background noise such as wind noise or heating, ventilation and air conditioning (HVAC) to improve the audio quality of recorded data. The device also includes variable-speed playback, enabling audio data to be played faster or slower, but without changing the pitch. Further embedded analog circuits include speaker and microphone amplifiers, and programmable gain amplifiers (PGA) with digital automatic level control (ALC) for more consistent playback.
Atsushi Bando, General Manager of Digital Solutions Division of Sanyo Semiconductor Products Division of ON Semiconductor, said: "On Semiconductor has launched this highly integrated LC823430TA, which enhances the product lineup to meet the needs of innovative and space-saving designs in the portable audio recording and playback market. Integrating a large number of digital and analog function modules in a single TQFP package not only saves space and reduces bill of materials, but most importantly, helps accelerate and simplify the development process in a rapidly changing competitive market. "
ON Semiconductor also provides driver-level and middleware-level software optimized for its proprietary DSP and further application-level software and support, which further speeds up and simplifies the customer's design process.
Package and price
Both the USB and non-USB versions of LC823430TA are packaged in TQFP128L, and the budgeted unit price for each 10,000-piece batch is $ 5.00.

LSZH cables is the abbreviation term of (low smoke halogen free) low smoke zero halogen electrical cables.FR is for flame retardant power cables, also for the short term of Fire Resistant Power Cables. The smoke released by these cables is non-toxic when fire happens. Therefore they are applicable for public places to protect instruments, equipments and people from potential harm.Fire resistant Power Cable will still keep the electrical power on within certain time in case of combustion.Flame retardant power cable may produce low gases and smoke after combustion.These cables are generally used in population-concentrated public places to have better fire safety and rescue capability.
Conductor:99.99% oxygen free copper or aluminum
Insulation/Sheath: LSZH FR formula added
Packaging: wooden steel drum, wooden/paper/plastic reels
l Low or no halogen acid gas release
