Freescale Semiconductor MC68882EI25AR

The MC68882 is a floating-point coprocessor for Motorola M68000-family systems, particularly the MC68020 and MC68030 host interfaces. It implements the ANSI-IEEE 754-1985 binary floating-point model and extends integer-only processing with dedicated arithmetic hardware and floating-point registers. This catalog entry identifies the exact code as MC68882EI25AR; the manufacturer-hosted family documentation verifies the MC68882 architecture, while the full suffix should be checked against supplied-lot paperwork.

The LCDChip API records 68-LCC (J-Lead). The established package register maps that name to 68-LCC.jpg; NXP's MC68882 family documentation includes a 68-lead PLCC package option. A precise EI25AR package drawing and lot-specific marking must still be confirmed before footprint approval.

Layout checks

• Confirm the exact 68-lead PLCC/J-lead drawing and pin-one orientation.
• Check land pattern, socket option and body outline.
• Verify lead condition and handling of the actual part.

The registered JPG is absent locally and on the production site; do not publish until the image and package match are verified.

Use the manufacturer MC68882 pin-out document for numbered lead assignments. The following are functional groups, not a substitute for the package-specific diagram.

Confirm all lead numbers and unused-pin instructions on the exact manufacturer package drawing.

Do not infer environmental grade or exact package dimensions from the unverified EI25AR suffix. Check original ordering and lot documents before engineering sign-off.

The MC68881 is documented as pin- and software-compatible with the MC68882 family, but performance and timing differ. Another MC68882 suffix is not automatically equivalent. Check package, clock grade, environmental rating, supply, bus timing, software assumptions and actual markings. No unverified internal alternative link is provided.

NXP hosts Motorola/Freescale's MC68882 Technical Summary (BR509) and the MC68882 product archive. These establish the family architecture and discontinued lifecycle. The API lists Freescale Semiconductor for MC68882EI25AR; the full exact suffix was not located in the family document and must be reconciled against controlled ordering records.

Inspect the full EI25AR marking, date and lot codes, traceability, 68-lead J-lead condition, storage history and electrical test documentation. A discontinued family designation does not by itself authenticate a supplied unit or establish its exact suffix rating.

Keep this product under review until an exact EI25AR manufacturer ordering reference, package drawing, supplied-lot marking and production JPG are confirmed. Use BR509 electrical and bus-timing tables for the final system analysis; do not release a page based solely on catalog metadata.
