This User Guide describes the technical features and programming interfaces of the Lantronix
DSTni-EX chip (hereafter referred to as “DSTni”).
DSTni is an Application Specific Integrated Circuit (ASIC)-based single-chip solution (SCS) that
integrates the leading-edge functionalities needed to develop low-cost, high-performance device
server products. On a single chip, the DSTni integrates an x186 microprocessor, 16K-byte
ROM, 256K-byte SRAM, programmable input/output (I/O), and serial, Ethernet, and Universal
Serial Bus (USB) connectivity — key ingredients for device- server solutions. Although DSTni
embeds multiple functions onto a single chip, it can be easily customized, based on the
comprehensive feature set designed into the chip.
Providing a complete device server solution on a single chip enables system designers to build
affordable, full-function solutions that provide the highest level of performance in both
processing power and peripheral systems, while reducing the number of total system
components. The advantages gained from this synergy include:
Simplifying system design and increased reliability.
Minimizing marketing and administration costs by eliminating the need to source
products from multiple vendors.
Eliminating the compatibility and reliability problems that occur when combining
separate subsystems.
Dramatically reducing implementation costs.
Increasing performance and functionality, while maintaining quality and cost
effectiveness.
Streamlining development by reducing programming effort and debugging time.
Enabling solution providers to bring their products to market faster.
These advantages make DSTni the ideal solution for designs requiring x86 compatibility;
increased performance; serial, programmable I/O, Ethernet, and USB communications; and a
glueless bus interface.
