STE10/100A

Controllers Overview

The STE10/100A is an Ethernet controller integrated circuit manufactured by STMicroelectronics. It supports IEEE 802.3 standards for 10BASE-T and 100BASE-TX networks, enabling data transmission rates of 10 Mb/s and 100 Mb/s. The device integrates a single transceiver and provides AUI and MII interface types for system connectivity. It operates on a maximum supply voltage of 3.3 V and functions within a temperature range of 0°C to +70°C. The component is housed in a PQFP-128 surface-mount package and supports both full-duplex and half-duplex communication modes.

Controllers Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify the specific revision and manufacturing date code upon acquisition, as production has ceased. Ensure compatibility with existing board designs before procurement due to potential supply chain limitations.

Controllers Selection Notes

Select this component only if legacy support for 10/100 Mbps Ethernet is required and the PQFP-128 package fits the PCB layout. Consider that newer alternatives may offer higher speeds or lower power consumption. Verify that the 3.3V logic levels and AUI/MII interfaces match the host processor requirements. Check for moisture sensitivity handling procedures during assembly.

Controllers Part Context

The STE10/100A belongs to the STE10/100 series of Ethernet controllers from STMicroelectronics. This family was designed to provide cost-effective solutions for embedded Ethernet applications. It serves as a bridge between the MAC layer and the physical medium, handling signal encoding and decoding for twisted-pair cabling.

Controllers Replacement Considerations

As the part is obsolete, direct replacements are limited. Review STMicroelectronics' current Ethernet controller portfolio for modern equivalents. Verify pinout compatibility and software driver availability when considering alternative components.
