General Description

1.5.1 C205 MAIN Board

The C205 MAIN board is a Main controller board. The primary functions of this board are receiving
print data from the host, generating the print image (Main), and sending the print image to the
engine controller via the Main interface. A 32-bit 20 MHz RISC CPU MB86930 (SPARKlite)
(location: IC15) is used, and the following memory chips and custom ICs are assigned to the 4 GB
memory space.
Memory chips
Font ROM: two 8M-bit ROMs (IC32, IC33)
Code ROM: two 8M-bit ROMs (IC12, IC13)
4M-bit DRAM (IC18, 19, 20, 21)
1K-bit EEPROM (IC5)
Custom ICs
ASIC E05A91 (IC1)
ASIC E05A93 (IC11)
ASIC E05B17 (IC16)
ASIC E05B27 (IC43)
ASIC E05B31 (IC38)
Other
Reset IC 953B (IC2)
