Oki Data CONFIDENTIAL
The main control PCB(TBX) of the 600dpi-Printer consists of a CPU, secondary cache SRAM,
ROM, RAM, EEPROM, Flash ROM, memory control LSI (CC1), interface control LSI (CIF2), IDE
HDD, PCI Bus Option and advanced interface.
(1) CPU
The CPU features a 64bit bus RISC PowerPC750GL processor. This operates at
800MHz, 6 times the speed of a 133MHz (bus clock) clock.
(2) Cache
The PowerPC750GL implements the following L1 & L2 caches.
Speed
: Same as CPU Core CLK
Capacity : Primary Cache: D cache = 32KB, I cache = 32KB
Secondary Cache: 1MB
(3) RAM
RAM is DDR_DIMM. RAM_DIMM capacity is 256MB or 512MB. Max capacity is
1GB. DDR_DIMM used at TBX are the same with the DIMM used at AS3 and
PX735/736/745/741.
(4) EEPROM
This is a 3.3V/32kbit EEPROM with an 8-pin DIP package mounted on the IC socket.
It stores various settings that the control unit manages.3
(5) ROM
A 64MB flash ROM is directly on the TBX PCB. It can store program, fonts, macro,
etc.
(6) Memory Control LSI (CC1)
This ASIC mainly controls the CPU I/F, memory, video data compression/extraction,
and video I/F with the PU.
(7) Interface Control LSI (CIF2)
This ASIC controls PU command I/F, the operation panel I/F, IDE I/F, Centro I/F, USB I/F,
PCI I/F, EEPROM, and SPD (SDRAM DIMM) I/F.
(8) IDE HDD
The IDE connector is directly set on the PCB. The IDE HDD exclusively molded into
an Assy is connected here. This is used to store font data, temporarily store video
data that has already been edited and upon registering form data.
() PCI Bus
In addition, two PCI I/F slots are provided for optional circuit boards.
100-pin:
This slot is not available (connector removed).
68-pin:
A Host USB board is provided as optional equipment.
(10) Advanced Interface
Standard
: Centronic Two-Way Parallel I/F (IEEE-1284)
USB (USB2.0) Interface
10/100 Base-TX, 1000Base-T Interface
Additional PCB : Host USB Board (68pin-PCI Bus Connection)
Security HDD (IDE bus)
