Active production — what it means for the BOM
The DS2502+T&R: RoHS3 compliant per the supplier record — no exemption expiry to track for EU market shipments.
1Kbit OTP EPROM with 1-Wire interface
Organised as 128 x 8 bits, the DS2502 is a one-time-programmable EPROM — once written, the data is permanent. No erase cycle, no wear-leveling concern. Communication runs over the single-pin 1-Wire bus, which carries both data and power on one line plus ground.
TO-92 package — board-fit and storage
Housed in a through-hole TO-92 (TO-226AA) package with formed leads — the same three-pin footprint as a standard small-signal transistor. The DS2502+T&R ships on tape and reel or cut tape, so it feeds into auto-insertion or hand-assembly lines. Through-hole mounting means no moisture-sensitivity level (MSL) bake requirement — store the reels in ambient conditions, no dry-bag needed.
