2-7. Memory Structure
The memory structure is divided into the following memory blocks:
1.
Set Memory
2.
Status Memory
3.
Chroma Memory
4
W/B Memory
5.
Channel Memory
6.
Image Flip Memory
7.
Picture Memory
8.
Fan Memory
CPU internal ROM: 512Kbyte Flash Memory
CPU internal RAM: 32Kbyte
External NVM:
8Kbyte EEPROM, 128byte EEPROM (FAN Memory)
The flow of data is described as follows. With the power cable plugged (Standby state), write all data as
initial values to the NVM (nonvolatile memory) using the application from outside, and then unplug the
power cable. When the power cable is plugged again, the memory data such as the Set Memory data that
are necessary for operation are selected from each memory block, and then processed into the internal
RAM. Once the power is turned on, the memory data such as the Status Memory data that are necessary
for the current video signal are selected from each memory block, and then processed into the internal
RAM.
If an adjustment is performed at this stage, the adjustment data is written in the NVM automatically (user
mode item) or when triggered by a memory operation (service mode/factory mode item) and stored.
Note that once the user makes an adjustment and performs a memory operation, the items that can be
adjusted in the Service Mode and the Factory Mode (W/B, Device Adjust) are stored in the NVM and the
factory default data is erased.

Section 3
Semiconductor Pin Assignments
The following describes the semiconductor types used in
this unit.
For semiconductors marked with page numbers in the
index, refer to the corresponding pages in this section.
However, in some cases incompatible types are also listed,
therefore, when a part is to be replaced, also refer to the
Spare Parts section.
In addition, for semiconductors with ID Nos., refer to the
separate CD-ROM titled “Semiconductor Pin Assignments”
(Sony Part No. 9-968-546-xx) that allows searching for
parts by semiconductor type or ID No.
The semiconductors in the manual or on the CD-ROM are
listed by equivalent types. Thus the external view or the
index mark indication may differ from the actual type.
Pin assignments and block diagrams are based on the IC
manufacturer’s data book.
