Datasheet in PDF, 412 KB, covering the 93AA86A/B/C, 93LC86A/B/C and 93C86A/B/C serial EEPROMs, the 16 Kbit Microwire family whose AA, LC and C prefixes indicate different supply voltage ranges. The A, B and C suffixes distinguish 8-bit, 16-bit and ORG-pin selectable organisation. The sheet is a reference for pinout, voltage limits and timing. Check the exact suffix printed on the chip before choosing a programmer profile, since the wrong organisation misreads the data, and back up the contents first.
