The MCP2200 device that you have received conforms
functionally to the current MCP2200 Data Sheet
(DS22228), except for the anomalies described in this
document. 

Revision A0 was not registered with the USB IF
as a compliant device. Revision A1 is registered
as a USB compliant device.

Use revision A1. Revision A0 parts were
primarily samples. All devices manufactured
after the second Work Week of 2010 are
revision A1 and USB compliant.

To determine the year and working week
correctly, look for the first four digits on the
package markings, which are Year (YY) and
Work Week (WW) codes. Anything after
1001NNN is USB compliant.

Revision A1 and earlier had a reduced
sustained throughput at higher baud rates on
the UART side of the bridge. When not using
hardware flow control on the UART, data could
be lost if attempting high data throughput when
the UART baud rate is high.

Use revision A2. The revision number can be
identified using 

Table 1

.

If using rev A1 or earlier: Enable the RTS and
CTS pins to enable hardware handshaking. The
throughput will be reduced, however, no data
will be lost.

None.

This document summarizes all silicon
errata issues from all revisions of silicon,
previous as well as current.
