Texas Instruments has discontinued this Stellaris ARM Cortex-M3 MCU, so it is no longer in production and cannot be ordered through the factory or authorized distributors as a current-production line item. There is no official TI successor listed for this exact order code, so any replacement requires a pin-compatible or function-compatible migration within the Stellaris family or to a newer TI MCU platform.
50 MHz Cortex-M3 with 32 KB Flash — fit for control and sensor fusion
The 50 MHz core, combined with the Cortex-M3's single-cycle multiply and hardware divide, gives enough headroom for real-time PID loops and protocol handling without an external DSP. The 8 KB SRAM is the tighter resource — it limits the data buffer for communications stacks (e.g., a full TCP/IP stack is impractical) and constrains the call stack depth for complex interrupt-driven code. Designs that need larger packet buffers or multiple large lookup tables will hit the SRAM ceiling quickly. The Flash endurance is standard for this class, but with only 32 KB, firmware OTA updates require a carefully managed bootloader and staging area.
The two 10-bit ADC channels provide basic analog sensing for current, temperature, or voltage monitoring. 34 general-purpose I/O pins are available in the 48-LQFP package, which is a 7x7 mm surface-mount footprint — compact enough for space-constrained PCBs but still hand-solderable for prototyping.
Sourcing reality for an obsolete part
There is no factory lead time to quote because the factory no longer makes it.
