Product details

50 MHz Cortex-M3 with integrated Ethernet and CAN

The LM3S8733-IQC50-A2T: It carries 128 KB of Flash and 64K x 8 SRAM, enough for moderate control and communication stacks.

Obsolete — no direct replacement on record

This part carries an official product status of Obsolete. There is no listed successor order code in the available records, so a pin-compatible direct replacement from TI's current Stellaris or Tiva-C portfolio is not confirmed. For production continuity, the only channel is the surplus and broker market. Any lot offered should be verified for date code and authenticity against the original TI marking.

Sourcing reality for a discontinued controller

Because the LM3S8733-IQC50-A2T is obsolete, standard distribution stock is depleted. Buyers should expect to work with date-code-locked inventory and plan for a one-time last-time-buy or a qualified substitute evaluation.
