Frequently asked questions
Where can I buy LM3S6420-EQC25-A2T and get a price?
We source this obsolete Stellaris MCU to order against an RFQ. Availability and pricing are confirmed at quote time through our independent distribution network. Submit an RFQ for current market pricing and stock status.
What is the closest pin-compatible alternative to LM3S6420-EQC25-A2T?
No official pin-compatible second source is listed for this part. The Stellaris family was superseded by TI's Tiva C Series (TM4C123x/129x), which are not pin-compatible but offer a software-migration path from the StellarisWare library to TivaWare. For a direct drop-in, you would need to source the exact LM3S6420 or a same-family sibling from surplus stock.
What is LM3S6420-EQC25-A2T's listed speed?
The core runs at 25 MHz, which is the maximum clock from the internal oscillator or an external source. This is the speed for the ARM Cortex-M3 core and peripheral bus.
What series is LM3S6420-EQC25-A2T?
It belongs to the Stellaris ARM Cortex-M3S 6000 series from Texas Instruments, a family of Cortex-M3 MCUs with integrated Ethernet MAC.
What compliance documentation does this part have?
The part is RoHS-compliant with NIPDAU lead finish. REACH and conflict minerals declarations are available from Texas Instruments. No UL or IEC certification applies at the component level.
