Cortex-M3 controller at 50 MHz — what the 108-ball BGA brings to the board
The LM3S1635-IBZ50-A2T: It is suited for embedded control applications — industrial automation, sensor interfaces, motor control, and human-machine interface panels — where a moderate-speed 32-bit core with a compact BGA footprint and a broad peripheral set is required.
For a buyer evaluating this part for a BOM line, the NRND status is the key decision gate: if the design is already in production and the part is qualified, sourcing through independent distribution against an RFQ is the practical path — but for any new design, a pin-compatible or functionally equivalent current-production member of the Stellaris family should be evaluated instead.
Memory and peripheral headroom — 128 KB Flash, 32 KB SRAM, 56 I/O
The 128 KB program memory is adequate for control firmware with moderate code complexity — think PID loops, Modbus stacks, or basic HMI logic — while the 32 KB SRAM provides room for data buffers, communication stacks, and real-time variables. The 4-channel 10-bit ADC covers basic analog sensing, though for higher-resolution or multi-channel analog front ends an external ADC would be needed.
