Peripherals that matter for industrial networking
The integrated 10/100 Ethernet MAC is the headline peripheral — it lets you build a connected sensor node or a small gateway without an external PHY (though you still need the magnetics and RJ-45).

Frequently asked questions
Is LM3S6952-EQC50-A2T obsolete and what is the replacement?
Yes, the LM3S6952-EQC50-A2T is listed as obsolete by Texas Instruments. No direct replacement part number is provided in the available records. For a pin-compatible alternative within the Stellaris family, you would need to cross-reference the LM3S6000-series datasheets — the LM3S6952 is a specific density and peripheral set, so a drop-in may not exist.
What are the exact specifications of LM3S6952-EQC50-A2T?
It includes a 10/100 Ethernet MAC, I²C, SPI, SSI, UART, QEI, and 43 GPIOs. The 3-channel 10-bit ADC is on-chip. The package is a 100-pin LQFP (14x14 mm).
