A new maker for the catalogue: 167 discontinued device orderables from the two Lattice Semiconductor-authored discontinuance notices on Lattice's own public PCN index — PCN#26-04 (Select Silicon Image Devices, 36 records; July 15, 2026) and PCN 03B-23 (ispMACH 4A, SATA, PanelLink — Select Devices, 131 records; revision B, May 24, 2024) — downloaded first-hand from latticesemi.com and opened in full. 128 records carry a printed alternate; the rest print the notice's own "No Alternative".
What is in the file: PCN#26-04 = 36 Silicon Image OPNs (SII5xxx / SII9xxx / SII1xxx HDMI-era devices in QFN / WFBGA / TQFP), only 2 with a named alternative OPN (both to SII9135ACTU). PCN 03B-23 = 131 ispMACH 4A (M4A3 / M4A5) and PanelLink (SII163 / SII164 / SII3531) orderables, 126 with a printed alternate device (LC4032V / LC4064V / LC4128V / LC4256V / LC4512V, with that device's package and lead count).
The two notices name alternates at different granularity — shipped as printed: PCN 03B-23's Exhibit A names an alternate DEVICE per row (not a full ordering part number), while PCN#26-04's Appendix A names an alternative OPN. The file never harmonises the two. PCN 03B-23 is revision B of PCN 03A-23 (December 27, 2023) — its last-time-buy clock runs from the initial notice, exactly as printed.
Schedule, as printed: PCN#26-04 — issued 2026-07-15, last time buy 2027-01-15 (still open), last shipment 2027-07-15, last time support 2028-07-15. PCN 03B-23 — initial notice 2023-12-27, revision B 2024-05-24, last time buy 2024-06-27, last shipment 2024-12-27 (both passed).
Verification standard: Lattice-authored notices only, downloaded first-hand from the OEM's own domain (no distributor mirror), parsed by printed baseline and header geometry with every row asserted at build, cross-validated against an independent layout extraction. Facts only — no notice prose reproduced beyond short operative quotations.
