2.2 Electrical Circuit Operating Principles
The electric circuit of the Stylus C50/60/C61/C62 consists of the following boards.
Main board:
Stylus C50
: C429 Main Board
*1
Stylus C60
: C418 Main/Main-B Board
*2
Stylus C61/C62
: C483/C484 Main-B Board
*3
Power supply board:
Stylus C50/C60
: C417 PSB/PSE
Stylus C61/C62
: C482 PSH (For 42V)
*1 : C429 Main board is used for the Stylus C50. Followings show you the
specification of the C429 Main board.
1) C429 Main : 3 in 1 ASIC + Soldering SOJ ROM (from the first mass production)
*2 : C418 Main/Main-B board is used for both the Stylus C60 and the Stylus Photo
810/820. Followings show you the specification of the C418 Main/Main-B board.
- For the Stylus C60
1) C418 Main : 2 in 1 ASIC + Soldering SOJ ROM (from the first mass production)
2) C418 Main/Main-B : 3 in 1 ASIC + Soldering SOJ ROM (Running change)
- For the Stylus Photo 810/820
1) C418Main/Main-B : 3 in 1 ASIC + Soldering SOJ ROM
(from the first mass production)
*3 : C483/C484 Main-B board is used for both the Stylus C61/C62. Followings show
you the specification of the C483/C484 Main-B board.
1) C483/C484 Main-B : 2 in 1 ASIC + Soldering SOJ ROM
(from the first mass production)
Note: CPU, ASIC and PROM is integrated as one chip (IC1) on the MAIN board.
This section provides operating principles of C418 Main/Main-B/C429 Main/C483
Main-B/C484 Main-B, C417 PSB/PSE and C482 PSH. Refer to Figure 2-16/Figure2-
17 for the major connection of the each boards and their roles.
