Main Board (TIG PWB)

2.1

Figure 2-2 provides the block diagram of the main control board (TIG PWB).

AR-C200P Rev.5

(1) CPU The CPU is PowerPC750CXe, a 64-bit bus RISC processor, which inputs an 100-MHz CLK (= BUS CLK), and operates at 450MHz that is 4.5 times the input.

(2) Cache PPC750Cxe has its cache only inside of it. Speed: Same as CPU Core CLK speed Capacity:

Primary Cache: 32K bytes in D-cache capacity, 32 K bytes in |-cache capacity Secondary Cache: 256 K bytes

(3) ROM ROM is to be inserted into the two 168 pin DIMM slots. The slot A is for program ROM and the slot B is for Japanese kanji fonts. The slot C is not assigned.

(4) RAM RAM is to be inserted into the three 168 pin DIMM slots. The DIMMs must be fitted in descending labeled type No. order into the slots 1, 3, 2 and 4. SDRAM DIMM Specifications: Speed: PC133 or more Capacity: 64/128/256/512 MB Configuration: Without parity. Without ECC. SPD information is required.

(5) EEPROM EEPROM, an 8-pin DIP package, is to be inserted into the IC socket. The EEPROM is of 16 Kbits for 3.3V power supply, and settings for controlling the controller block are stored in it.

(6) Flash ROM A 4Mbyte flash ROM is surface-mounted on the TIG board. The flash ROM is composed of four 2048k-by-16bit chips, and fonts and macros can be stored in it.

(7) Memory Control LSI (CAI) A 696-pin BGA package ASIC made by NEC. The chip mainly controls a CPU I/F, memory, video data compression and decompression, and a PU-video I/F.

(8) Interface Control LSI (C2) A BGA package ASIC made by Toshiba, which controls a PU command I/F, operator panel I/F, IDE I/F, Centronics I/F, USB I/F, PCI I/F, EEPROM and a SPD (SDRAM DIMM) I/F.

(9) IDE HDD An IDE connector is surface-mounted on the board to which an IDE HDD assembled using exclusive molds will be connected. The IDE HDD is used for storing font data, spooling edited video data and registering form data.

(10) PCI Bus Option Two PCI I/F slots are provided for option board use. The bus, which uses an Oki Data original connector, can accept an Ethernet board. (11) Host Interface Standard: Centronics two-way parallel I/F (IEEE-1284-compliant) USB (USB1.1-compliant) Additional Board: (connected to PCI BUS) Ethernet Board

Figure 2-3

The engine control block (PU) is controlled by the engine controller board (K71 PWB) which consists of a CPU (MSM66Q577), general LSI chip, flash ROM, EEPROM, pulse motor drivers and a video memory (see Figure 2-3).

(1) CPU

This, a 16-bit CPU with an AD converter (OKI MSM66Q577), controls the entire system.

(2) General LSI

This LSI (UPD65454GD-241-LML, UPD65946GD-137-LML), which is contained in the printer engine control block, incorporates 4 megabits of video memory and has functions such as engine-controller interfacing, LED interfacing, motor control, sensor input, video memory control, main scan color misalignment correction, skew correction and high-voltage power supply control.

AR-C200P Rev.5

157

(3) MCON LSI This LSI is used for inport of SENSORSs and the cntrols of Pulse Motors, Cluches,FANs and High Voltage Power Suply.

(4) Flash ROM The flash ROM (29F800-70) is of 8-Mbits, and PU programs are stored in it.

(5) EEPROM The EEPROM (NM93C66N-NW) is of 4-Kbits, and mounted on the board with an IC socket. Correction values are stored in it.

(6) Pulse Motor Driver

The pulse motor driver (A2919S8LBTR, A3955SLBTR,MTD2005) drives the eight pulse motors to revolve the ID and transport media.

(7) SRAM This SRAM (628100LG-55L) is used as working memory of the CPU.

(8. SDRAM This SRAM (56V16160T) is used as data memory of the DCON LSI.

2.3 Power Units

There are a low voltage power unit consists of an AC filter circuit, low voltage power circuit and heater driver circuit, and a high voltage power unit organizes a high voltage power circuit.

(1) Low Voltage Power Unit

This circuit generates the following voltages:
