ST802RT1 not for new projects






ST802RT1B/A
  -  10/100 Ethernet Transceiver
48-pin LQFP 7 x 7 package
Description
The ST802RT1x is a high-performance fast Ethernet physical layer interface for 10Base-T, 100Base-TX and 100Base-FX applications. It is designed using advanced CMOS technology to provide MII and RMII interfaces for easy attachment to 10/100 media access controllers (MAC).
The ST802RT1x supports the 100Base- TX of IEEE802.3u and 10Base-T of IEEE802.3i and 100Base FX of IEEE 802.3u (B version only).

The ST802RT1x supports both half-duplex and full-duplex operation at 10 and 100 Mbps operation.
Its operating mode can be set using auto-negotiation, parallel detection or manual control. It allows for the support of autonegotiation functions for speed and duplex detection.
The automatic MDI / MDIX feature compensates for the use of a crossover cable.

With auto MDIX, the ST802RT1x automatically detects what is on the other end of the network cable and switches the TX & RX pin functionality accordingly.

Features
  • IEEE802.3 10Base-T and IEEE802.3u 100Base-TX, 100Base-FX (ST802RT1B only) transceiver
  • Support for IEEE802.3x flow control
  • Provides full-duplex operation in both 100 Mbps and 10 Mbps modes
  • Register bit strap during HW reset
  • Auto MDI-X for 10/100 Mb/s
  • Auto-negotiation
  • Provides loop-back mode for diagnostics
  • Programmable LED display for operating mode and functionality signaling
  • MII / RMII interface
  • MDC / MDIO serial management interface
  • Optimized deterministic latency for real-time Ethernet operation
  • Supports external transformer with turn ratio 1.414:1 on Tx/Rx side
  • Self-termination transceiver for external components and power saving
  • Operation from single 3.3 V supply
  • High ESD tolerance
  • 48-pin LQFP 7 x 7 package
  • Extended temp. range: -40 C to +105 C
  • Power dissipation < 315 mW (typ)
