IDE I/F
Interface circuit for IDE hard disk.
BUS Arbitration SDRAM CTL
Control circuit for arbitration of bus and external SDRAM.
I/F
Interface circuit for Flash Memory, PC Card, and CF Card.
UART
Port for servicing.
When overwriting of firmware by CF fails, firmware is over-
written by connecting this port to the RS-232-C port of a PC
with an adapter.
SIO
Interface serial data for sub-processor.
CPU
Controls all ASIC circuits.
Thumbnails
Pixel conversion circuit for formation of thumbnails.
(b) SDRAM IC252, 253
128Mbit x 2 short-term image storing region for non-com-
pressed images and compressed images.
(c) PLL
Forms 4 Fsc (14.4MHz) into 108MHz by multiplying it 7.5
times.
(d) Flash ROM IC227
Stores the program for ASIC drive in the Flash ROM.
When the power is turned on, the program is loaded to ASIC
from this Flash ROM.
(e) CF Interface Circuit IC221, 222, 223, 224, 225, 226, 229,
231
Buffer circuit for I/O to CF card.
I/O through buffer using LCX245.
(f) PC Card Interface Circuit IC232, 233, 234, 235, 236, 237,
238, 239
Buffer circuit for I/O to PC Card.
Converts 3.3V to 5V level using translating tranceiver
LVX3245 and performs buffering.
This Flash ROM and CF interface is on the same bus with
the PC Card interface.
(g) HDD Interface Circuit IC241, 242, 243, 244, 245
I/O buffer circuit for 3.5 inch IDE hard disk.
Converts 3.3V to 5V level using translating tranceiver
LVX3245 and performs buffering.
(h) RESET IC247
ASIC external reset circuit.
(i) Synch Insertion Circuit Q2501, 2502, 2503

CODER, EEPROM, RS-232-C, and RS-485.
(b) EEPROM IC281
Save data circuit. Non-volatile memory.
(c) RESET IC272
External reset circuit.
(d) Power outage detection circuit. IC273
(e) RS-232-C communications circuit. IC274, 275, 276
Interface for sending/receiving external RS-232-C signals.
(f) RS-485 communications circuit. IC278, 279, 280, 281
Interface for sending/receiving external RS-485 signals.
