ENC28J60
The ENC28J60 devices that you have received conform
functionally to the current Device Data Sheet
(DS39662C), except for the anomalies described in this
document.
The silicon issues discussed in the following pages are
for silicon listed in Table 1. The silicon issues are
summarized in Table 2. Issues specific to technical
conformance with IEEE Std. 802.3 are listed in Table 3.
Data Sheet clarifications and corrections start on page 9,
following the discussion of silicon issues.
The silicon revision level can be retrieved by querying
the read-only EREVID register, located at address 12h
in Bank 3 of the device’s Control register space. Please
refer to the Device Data Sheet for detailed information
on accessing this register. The values for the various
ENC28J60 silicon revisions are shown in Table 1.
Note: This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current. Only the
issues indicated in the last column of
Table 2 and Table 3 apply to the current
silicon revision (B7).
