4.1 MSD209GL

4.1.1 General Description
The MSD209GL is a highly integrated controller IC for LCD/PDP DTV

applications with resolutions up to full-HD(1920X1080).It si configured
with an integrated triple-ADC/PLL, a multi-standard TV video and audio
decoder, a motion adaptive video de-interlacer, a scaling engine, the
MStarACE-3 color engine, an advanced 2D graphics engine, a transport
processor, a high-definition(HD) MPEG video decoder, a
high-definition(HD)H.264 video decoder, a RealVideo decoder, a JPEG video
decoder, a MPEG-4 decoder, and a 24-bit DSP for MPEG audio decoding, a
DVI/HDCP/HDMI receiver, and a peripheral control unit providing a variety
of HDTV control functions.

For digital TV application, the MSD209GL comprises an MPEG-2

transport processor with advanced section filtering capability, an MPEG-2
(MP@HL profile) video decoder, a MPEG-4 decoder, a H.264 video decoder,
and an audio DSP decoder for MPEG audio streams, MPEG layer I and II digital
audio decoder with analog audio outputs that are designed to support
existing and future DVB-T programs while handing conditional access.
Furthermore, it is also possible to decode JPEG, RealVideo streams, and
MP3 formats from external sources such as USB interface.

For analog TV, the MSD209GL includes NTSC/PAL/SECAM multi-standard

video decoder comprising a 3D motion adaptive comb filter and time-based
correction, and a NICAM/A2 audio decoder to support worldwide television
standards. The MSD209GL is also configured with a VBI processor to decode
digital information such as Close
Caption/V-chip/teletext/WSS/CGMS-A/VPS. In addition, the MStar advanced
LCD TV processor enhances video quality, motion adaptive de-interlacer,
picture quality adjustment units, and MStarACE-3 color engine.

With USB 2.0 host controllers, UART, IR, SPI, I2C, and PWM, the

MSD209GL fulfills all requirements in advanced DTV sets. To reduce system
costs, the MSD209GL also integrates intelligent power management control
capability for green-mode requirements and spread-spectrum supports for
EMI management.

GENERAL DESCRIPTION

The W971GG6JB is a 1G bits DDR2 SDRAM, organized as 8,388,608 words
8 banks 16 bits. This device achieves high speed transfer rates up to
1066Mb/sec/pin (DDR2-1066) for general applications.。

4.4 Program SPI FLASH：EN25B64-100FIP（U7）

4.4.1

The EN25B64 is a 64M-bit (8192K-byte) Serial Flash memory, with advanced
write protection mechanisms, accessed by a high speed SPI-compatible bus.
The memory can be programmed 1 to256 bytes at a time, using the Page Program
instruction.
The EN25B64 has one hundred twenty-eight sectors including one hundred
twenty-seven sectors of 64KB, one sector of 32KB, one sector of 16KB, one
sector of 8KB and two sectors of 4KB. This device is designed to allow
either single Sector at a time or full chip erase operation. The EN25B64
can protect boot code stored in the small sectors for either bottom or
top boot configurations. The device can sustain a minimum of 100K
program/erase cycles on each sector.

SIGNAL DESCRIPTION

PIN Names

Serial Data Input (DI)
The SPI Serial Data Input (DI) pin provides a means for instructions,
addresses and data to be serially written to (shifted into) the device.
Data is latched on the rising edge of the Serial Clock (CLK) input pin.
Serial Data Output (DO)
The SPI Serial Data Output (DO) pin provides a means for data and status
to be serially read from (shifted out of) the device. Data is shifted out
on the falling edge of the Serial Clock (CLK) input pin.
Serial Clock (CLK)
The SPI Serial Clock Input (CLK) pin provides the timing for serial input
and output operations. ("See SPI Mode")
Chip Select (CS#)
The SPI Chip Select (CS#) pin enables and disables device operation. When
CS# is high the device is deselected and the Serial Data Output (DO) pin
is at high impedance. When deselected, the devices power consumption will
be at standby levels unless an internal erase, program or status register
cycle is in progress. When CS# is brought low the device will be selected,
power consumption will increase to active levels and instructions can be
written to and data read from the device. After power-up, CS# must
transition from high to low before a new instruction will be accepted.
Hold (HOLD#)
The HOLD pin allows the device to be paused while it is actively selected.
When HOLD is brought low, while CS# is low, the DO pin will be at high
impedance and signals on the DI and CLK pins will be ignored (don’t care).
The hold function can be useful when multiple devices are sharing the same
SPI signals.

Write Protect (WP#)
The Write Protect (WP#) pin can be used to prevent the Status Register
from being written. Used in conjunction with the Status Register’s Block
Protect (BP0, BP1and BP2) bits and Status Register Protect (SRP) bits,
a portion or the entire memory array can be hardware protected.
