Frequently asked questions
Can the 8.4MHz bus and 512B RAM support 1 kHz continuous-sampling across three A/D channels?
The 8.4MHz clock provides roughly 8 400 cycles per 1 ms sample period — sufficient for interrupt-driven 3x16b acquisition. The 512B RAM becomes the constraint: three channels at 2 bytes per sample consumes 6 bytes per cycle, yielding approximately 85 ms of buffered data before overwrite. Suitable for transient capture; not a deep waveform recorder without external memory.
What is the thermal derating posture of the 64-LQFP at 85°C ambient with all 14 I/O active?
The spec table does not publish a per-pin derating curve. At -40 to 85°C ambient with near-rated sink current on all 14 I/O, the thermal margin narrows significantly in the 64-LQFP (10x10mm). Verify the actual per-pin current limits against the TI datasheet thermal section — the datasheet governs the derating boundary, not the spec table.
