The 1.5 KB RAM handles a few local buffers and a small call stack; any significant data buffering needs external serial RAM or careful code partitioning. No commercial-grade variant exists for this order code; the extended range is baked into the silicon and package. ## Active lifecycle — no EOL risk for new designs The EnergyLite family has broad market traction, so secondary sourcing through independent distribution is straightforward if primary channel allocation tightens. ## 20-TSSOP package — layout notes Housed in a 20-lead TSSOP with 0.173\" body width and 4.40 mm nominal width.
