Obsolete — sourcing this part now means the independent channel
For BOM lines that still require this exact order code, procurement must turn to the independent distribution channel — surplus inventory, new-old-stock, or broker-sourced material. If your design can tolerate a pin-compatible migration, the Stellaris family includes other Cortex-M3 density variants in the same 108-BGA footprint, but no direct drop-in replacement is documented here.
108-LFBGA — what the package means for the assembly line
The 108-ball LFBGA with a 10×10 mm body and 0.8 mm ball pitch is a fine-pitch BGA that demands careful PCB land pattern design and X-ray inspection post-reflow. The 67 I/O signals route through the ball array, so fanout vias and escape routing on a four-layer board are standard practice.
80 MHz core with 384 KB Flash — sizing the firmware and throughput budget
The 80 MHz Cortex-M3 core delivers roughly 1.25 DMIPS/MHz, or about 100 DMIPS peak, adequate for real-time control loops, protocol stacks, and data processing in industrial applications. The 384 KB Flash is sized for mid-complexity firmware — enough for a FreeRTOS-based application with a TCP/IP stack and application logic, but tight for a full GUI or heavy signal-processing library. The 64 KB SRAM supports moderate data buffering; if your application needs large frame buffers or extensive lookup tables, budget external memory via the EBI/EMI interface.
