4.0 General Description

4.1 Overview

The SL11RIDE is a low-cost, high-speed Universal Serial Bus RISC-based Controller board. It contains a 16-bit RISC processor

with built-in SL11RIDE ROM to greatly reduce firmware development efforts. Its serial flash EEPROM interface offers low-cost

storage for USB device configuration and customer product specific functions. New functions can be programmed into the I2C by

downloading them from a USB Host PC. This unique architecture provides the ability to upgrade products, in the field, without

changing the peripheral hardware.

4.2 Features of SL11RIDE

• Two-wire serial EEPROM (I2C) interface port, with SL11RIDE ROM firmware support, to allow on board flash EEPROM

programming

• Supports 12-MHz/48-MHz external crystal or clock

• 6Kx8 internal Mask ROM with built-in BIOS

• Supports up to the maximum USB transfer rate of 12 Mbits/sec

• Power source requires only 3.3V, and it can be powered via a USB host PC or a Hub

• Resume, Suspend, and Low-power modes are available

• Includes the necessary firmware to function as a USB to IDE/ATAPI controller

4.3 Applications

Cypress offers a Developer’s Kit with all its product lines. These Developer’s Kits include: ATAPI/IDE firmware, multiple peripheral

Mini-port class drivers for Windows98/2000, MAC 8.6 or higher available object code, a complete ATAPI/IDE solution reference

design, and a demo board.

The SL11RIDE offers solutions for interfacing USB to IDE/ATAPI peripheral products including HDD, CD-ROM, CD-R/RW, ZIP

drives, LS120, MO drives, Compact Flash, Disk on Chip, Tape drives, Smart Media cards, ORB, and CLIK, and MicroDrives.

4.4 Low Power Consumption

The SL11RIDE offers various power consumption modes. The maximum power consumption at 48-MHz operation, including USB,

is less then 30 mA, but on the average it consumes around 10 mA.

The following are measurements taken under different setups of the SL11RIDE:

Idle Mode:

2.0 mA (USB is on, CPU runs at 48 MHz)

During Reset:

3.0 mA (Reset is held LOW)

Post Reset:

12.5 mA typical at 48 MHz
