Frequently asked questions
What is the closest pin-compatible alternative to the LM3S3739?
TI transitioned the Stellaris 3000 series to the Tiva C Series (TM4C family), but the specific 128KB/61-I/O density tier does not carry a confirmed pin-compatible cross-reference in the available record. A Tiva migration would require pinout and register-level review rather than a drop-in swap.
What speed and memory does the LM3S3739-IQC50-A0T list?
The part runs at 50MHz on an ARM Cortex-M3 core with 128KB FLASH program memory and 64KB SRAM, sourced and quoted to order against an RFQ through independent distribution.
What series does the LM3S3739-IQC50-A0T belong to?
The LM3S3739-IQC50-A0T is a member of the Stellaris ARM Cortex-M3S 3000 series — Texas Instruments' first-generation Cortex-M3 microcontroller family before the brand was consolidated into Tiva C Series.
