9.2 Block Diagram of Main Control Board
Figure 9.2
The major Components in Main Controller are:
Micro-controller (U6)
SH7034 ( External 16 Bit & Internal 32 Bit in Data Bus) is based on Hitachi SH1 as its CPU Kernel and
integrated with lots of on-chip peripherals which are required to build a system like this Label Printer. These rich
on-chip Peripherals, Timer, DMA controller, Interrupt Controller, DRAM Controller, A/D convert , Serial
communication interface, Pattern generator and I/O ports make the Electrical H/W for this printer be compact and
high performance.
