Main Board Control
The main controller consists of the ASIC(CPU, image processor, PC I/F, scanner interface, fax
modem and printing process I/F part). The CPU handles BUS control, I/O interface, scan inter-
face, PC interface and other miscellaneous driver circuits.
1) Main Board
- The main PBA is responsible for sending current image video data to the LSU of the
machine, controlling the motor drive circuit as well as monitoring the paper exit sensor, cover
open switch and OPE panel inputs.
2) Main Controller
- PE220 CPU: Chorus2, 16/32bit RISC architecture using ARM7TDMI core.
- Phaser 3200 CPU: Chorus M, 32bit RISC architecture using ARM 920T core.
The main CPU controls the whole system according to the program code which is stored on
Flash-ROM memory.
- Summary of the Key Function Block:
• (PE220) 1.8V for internal Core, 3.3V for I/O Pad with 4KByte Cache.
• (Phaser 3200) 1.3V for internal Core, 3.3Vfor I/O Pad with 16KB I-Cache and 16KB D-
Cache.
• Image Processor included.
• On-Chip clock generator with PLL.
• Memory and External Bank Control.
• DMA Control (5-Channel for PE220, 16-Channel for Phaser 3200)
