SMSC Announces Single Chip Non-PCI 10/100 Ethernet MAC+PHY for Embedded Applications.

Business/Technology Editors


Standard Microsystems Corporation (NASDAQ: SMSC) announced today the availability of samples of its LAN91C111 Non-PCI 10/100 Mbps Single Chip Ethernet MAC+PHY Controller. The LAN91C111 integrates the IEEE 802.3 compliant Fast Ethernet Media Access Controller (MAC), the 10/100 Mbps Ethernet Physical Layer (PHY) and transmit and receive buffer memory (SRAM) into a single device to deliver full functionality in a high performance compact design, reducing production cost and board space. It is designed to facilitate the implementation of a third generation of Fast Ethernet connectivity solutions for embedded applications that use ARM, SH, MIPS, 68K/Coldfire, PowerPC and other RISC processors.

As the demand for network speed for multimedia and World Wide Web applications continues to increase, the LAN91C111 Fast Ethernet controller allows OEMs to build embedded Ethernet systems to meet the evolving needs of the network. The LAN91C111 provides a configurable, generic bus interface compatible with popular embedded processor host interfaces, including ARM, Hitachi SH, Power PC, ColdFire, 68000, and MIPS R3000. It provides a flexible slave interface for easy connectivity with industry-standard buses to handle synchronous and asynchronous transfers. With these features, the LAN91C111 is an ideal solution for Ethernet connectivity in a broad range of embedded devices such as set-top-boxes, ATM machines, switching hubs, printers, motherboards, adapter cards, security systems, network appliances and even game consoles.

The LAN91C111 offers advanced features such as SMSC's patented MMU (Memory Management Unit) architecture and a 32-bit wide internal data path. This I/O mapped architecture can sustain back-to-back frame transmission and reception for superior data throughput and optimal performance. It dynamically allocates buffer memory in an efficient buffer utilization scheme, reducing software tasks and relieving the host CPU from performing these housekeeping functions. The LAN91C111 features early transmit and receive to increase throughput. Only 16 bytes of I/O or memory address space are required, minimizing processor resources.

The integrated PHY interfaces to twisted pair Ethernet applications through standard magnetics. It contains the entire physical layer including Physical Coding Sublayer (PCS), Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent (TP-PMD) and AutoNegotiation (AUTONEG). The on-chip AutoNegotiation algorithm enables the controller to automatically configure itself for 100 or 10 Mbps and Full or Half Duplex operation. The addition of internal output waveshaping circuitry and on-chip filters eliminates the need for external filters required in 100BASE-TX and 10BASE-T applications.

The device also supports external PHY through the Media Independent Interface (MII) pins. External Physical Layer (PHY) support expands this controller's capabilities, so it can support fiber and other media.

The LAN91C111 features low power 3.3-volt operation in a small 128 pin TQFP or 128 pin QFP package. It is optimized for use in designs requiring low power and a small form factor package. With built-in Media Access Layer (MAC), Physical Layer (PHY) and Internal SRAM, the LAN91C111 is the simplest and most cost efficient solution for Ethernet connectivity. Also, the LAN91C111 Ethernet controller eliminates design complexity due to critical timing, layout and other complicated hardware parameters required to implement standard PCI system solutions.


The LAN91C111 will be supported by a complete collateral package, including reference designs evaluation boards and drivers. An NDIS4 driver for Windows98 is available now. Drivers for VxWorks and Linux are in development and are expected to be available Q1 and Q2 of 2001, respectively. ETX Utility Software, available now, greatly simplifies development.

Price, Package and Availability

The LAN91C111-NE is packaged in a 128 pin TQFP and priced at $17.65 each in quantities of 10,000. The LAN91C111-NC is packaged in a 128 pin QFP and is priced at $17.05 each in quantities of 10,000. Samples, an evaluation board with reference schematics and BOM, an NDIS4 driver for WIndows98 and ETX Utility Software are available immediately. Please contact your local SMSC sales office for more information.
