Video Imager

Interface

Interfaces directly with Hyundai CIF, VGA and SVGA CMOS sensors. Other

sensors can be supported with the SE401’s flexible GPIO architecture.

Video

Compression

Engine

Includes a proprietary image compression engine with variable compression rates.

For maximum performance the compression engine supports DMA to the Frame

Buffer and on to the USB Serial Interface Engine.

16-bit Processor

The SE401 USB Video Imager Controller has a built-in 16-bit EndPoints QT

processor with its basic operating firmware in internal 6K X 16 masked ROM. The

QT processor operates with a specialized instruction set designed for highly

efficient coding of processing algorithms and USB transaction processing.

Functionality of the QT Processor can be extended using external EEPROM

USB Subsystem

The SE401 USB Video Imager Controller contains a complete USB subsystem with

a Serial Interface Engine (SIE) and built-in transceiver operating at full 12Mbits/sec

data rate. The USB Subsystem meets the Universal Serial Bus (USB) specification

v1.1. In addition to the default control endpoint, the SE401 supports three

additional endpoints, which may be configured as Isochronous or Bulk/Interrupt.

PLL Clock

Generator

An inexpensive 12 MHz external crystal may be used with the SE401 USB Video

Imager Controller. The controller incorporates PLL circuitry to generate the internal

48MHz clock requirements of the device. Alternatively, an external 12 MHz clock

signal may be used instead of the crystal.

Internal

Ram Buffer

The SE401 USB Video Imager Controller contains 1.5K X 16 of internal buffer

memory. The memory is used for expansion code and data, such as USB packets.

It is accessed by both the processor and the Serial Interface Engine (SIE). USB

control packets are automatically routed to the buffer memory.

6K ROM BIOS

Internal 6K X 16 Masked ROM contains a BIOS (Basic Input/Output System) with

functions to manage Power-On initialization, USB Transactions, USB Enumeration,

USB Power Management, Expansion EEPROM Scan support, Memory

Management etc.

UART Interface

Supports 1200 to 115.2K baud at TTL-levels.

General Purpose

I/O

Up to 32 general purpose I/O signals are available. GPIO may be configured for

special purpose functions such as the SPORT Synchronous Serial Interface for

audio codec etc.

Serial EEPROM

Support

The SE401 USB Video Imager Controller serial EEPROM interface is used to

provide access to external EEPROMs. The interface is implemented using general-

purpose I/O signals and can support a variety of serial EEPROM formats.

External Memory

Interface

A multiplexed address port and 16-bit data port has been provided to interface to

an external SRAM, DRAM or EEPROM with programmable wait states. The port

provides RAS, CAS, RD and WR control signals for data access and refresh cycles

to the DRAM.

Development Tools

C Compiler, Assembler and debugging tools are available to qualified customers.
