Epson C11C586001 2.3.1 C543 Main Circuit Board

EPSON Stylus PHOTO RX600/610, RX620/630 Revision C

Operating Principles Electric Circuit 18

2.3.1 C543 Main Circuit Board

2.3.1.1 Feature

USB 2.0 with multi-end points allows high speed SPC without HUB

SOC with printer control, scanner control, PT control, CPU SuperMacro

1CPU (NA85E2C by NEC) controls printer, scanner and PT unit

256Mbit*16 SDRAM (2 units)

A6615 drives DC x 2 and DC x 2 with 1Chip to motor driver

SOC obtains wider band ranges by setting action frequency of local SDRAM

to 96MHz

Copy function allows faster process with SOC to scan, and to generate 2-

values, microwave, image buffer instead of going through CPU bus.

Equipped with a color LCD (2.5-inch DTFD liquid crystal display) as

standard.

Low current allows LCD to reduce power consumption in low power mode as

follows:

•Lowering power supply voltage

•Shutting off optical current for optical sensor

•SLEEP mode for motor drive

•Saving the power for printer with no exciting motor

•Saving the power for scanner by turning off the lamp

•Equipped with printer tray open sensor
