FRAM vs Flash — what it means for the BOM
8.5 KB FRAM writes at bus speed with no erase cycle. For a gas meter logging data every few seconds, this eliminates wear-leveling and cuts write-energy budget.
Supply range and power rail
1.8 V to 3.6 V supply covers single Li-ion cell or two alkaline cells directly. Brown-out detect on-chip and configurable.
Lifecycle and sourcing
Active lifecycle status — no last-time-buy or end-of-life notice. Sourced and quoted to order through independent distribution.
