3.1
The SL11R is a low-cost, high-speed Universal Serial Bus (USB) RISC based Controller. It contains a 16-bit RISC processor with
built-in SL11R BIOS ROM to greatly reduce firmware development work. Its 2-wire serial EEPROM interface offers low cost
storage for USB device configuration and customer’s product-specific functions. New functions can be programmed into the 2-wire
serial interface 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.
The SL11R Processor can execute code from either internal ROM/RAM or external ROM and SRAM. The SL11R Programmable
bidirectional Data Port supports both DMA and I/O modes. A built in USB port supports data transfers up to 12 MBits/sec which
is the maximum USB transfer rate. All USB protocol modes are supported: Isochronous (up to 1024 bytes/packet), Bulk, Interrupt,
and Control. The SL11R requires a 3.3-Volt power supply, which can be powered via a USB host PC or a Hub. Suspend/Resume,
and Low power modes are available.
The SL11R offers an optimal solution for a variety of peripheral products such as: Scanners, Digital Cameras (Video and Still),
Color Printers, Multi-function Units (MFU), Faxes, External Storage devices, Monitors, Connectivity boxes, and other peripherals
that traditionally interface via EPP or SCSI to a host PC.

Introduction
Universal Serial Bus
The SL11R is a Cypress USB Controller, which provides multiple functions on a single chip.
Quick stream data Transfer engine, which contains a small set of RISC instructions designed for the
SL11R USB controller.
‘QT’ is a naming convention that represents QT Engine utility tools. For example: ‘QTS’ indicates all
tools, which interface with the RS232 serial interface port.

Phase Lock Loop.
Pulse Width Modulation
Digital Video Camera
Multi Function Units
Watch Dog Timer
Random Access Memory
Enhanced Parallel Port: An asynchronous, byte-wide, bidirectional channel controlled by the host de-
vice. This mode provides separate address and data cycles over the eight data lines of the interface.
SL11R Registers:
A simulation model similar to 80x86 BIOS
R0-R7 Data registers or general-purpose registers.
R8-R14 Address/Data registers, or general-purpose registers.
R15 Stack pointer register.
