DANGER
This DVD Player uses a visible Laser Beam.
The DVD Player is a class 1 laser product.
To prevent direct exposure laser beam. When
the enclosure is opened, visible laser radiation
is present , which is harmful to the eye.
Use of control or adjustments or performance
of procedures other than those specified herein
may result in hazarded radiation exposure.
Do not open the covers and do not repair
yourself.
Refer to the qualified personnel for servicing.
The lightning flash with arrowhead symbol, within
an equilateral triangle, is intended to alert the
user to the presence of uninsulated "danger
voltage" within the product's enclosure that may
be of sufficient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to presence
of important operating and servicing instructions.

General Description
The AD6315 is a VFD (Vacuum Fluorescent Display
or fluorescent Indicator Panel) driver that is driven
on a 1/4- to 1/12- duty factor. It consists of 16
segments and 4 grids output lines, 8 segments /
grid output driving lines, a display memory, a control
circuit, and a key scan circuit. Serial data is input to
the AD6315 through a 3-wire serial interface. This
VFD driver is ideal as a peripheral device for a
single-chip microcomputer

reception of a command. Data input after
STB falling is processed as a command.
While command data is processed, current
processing is stopped, and the serial

BD3871 SOUND PROCESSOR
DescriptionDimension (Units : mm)
BD3871FS is a sound processor for CD/MD radio
cassette player. This IC provides all functions,
such as input selector (3 input sources), an input
gain amplifier (25dB, 27dB, 29dB),and a surround,
tone (bass, treble). This IC can be controlled
by a 2-wire serial data interface.

1) Can select center frequency and Q value of Bass
characteristics by external components.
2) Mute switch at the input terminal can reduce cross talk.
3) Surround function is composed without external components.
4) Ideal for energy-saving designs with low current consumption
due to the adoption of the BiCMOS process, allowing easy-design
of the regulator blocks in the set.

The SST39VF08 8 device is a 1M x8 CMO S Mult i-P urpose
Flash (MPF) manufactured with SST’s proprietary, high
performance CMOS SuperFlash technology. The split-gate
cell design and th ick-oxide tunneling in jector attain better
reliability and manufacturability compared with alternate
approaches. The S ST39V F088 wr i tes (P rogram or E rase)
with a 2.7-3.6V power supply. It conforms to JEDEC standard pinouts for x8 memories.
Featuring high performance Byte-Program, the
SST39VF088 device provides a typical Byte-Program time
of 14 µsec. The devices u s e Toggle Bit or Data# Polling to
indicate the comp letion of Program operation. To protect
against inadver ten t wri te, they have on-chip hardware and
Software Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, these
devices are offered with a guaranteed endurance of 10,000
cycles. Data retention is rated at greater than 100 years.
The SST39VF088 device is suited for applications that
require convenient and economica l updating of program,
configuration, or da ta memory. For all system appl i ca tio ns,
they significantly i mp r ove performa nc e an d re liability, while
lowering power consumption. They inherently use less
energy during Erase and Program than alternative flash
technologies. The tota l energy consumed is a function of
the applied voltage, curre nt, and time of ap plic ation. S inc e
for any given voltage range, the SuperFlash technology
uses less current to program and has a shorter erase time,
the total energy consumed during any Erase or Program
operation is less than alternative flash technologies. They
also improve flexibility while l owerin g the cost for program ,
data, and configuration storage applications.
The SuperFlash technology provides fixed Erase an d P r ogram times, independent o f the num ber of Erase/ Program
cycles that have occurred. Therefore the system software
or hardware does not have to be modified or de-rated as is
necessary with al ternativ e flas h techn ologies , whos e Erase
and Program times i ncrease with accumul ated Erase/P rogram cycles .
To meet high density, surface mount requirements, the
SST39VF088 is offered in 48-lead TSO P packaging. See
Figure 1 f or pi n assign ments .
