The MCP9800/1/2/3 parts you have received conform
functionally to the MCP9800/1/2/3 Data Sheet
(DS21909B), except for the anomalies described
below.
All of the issues listed here will be addressed in future
revisions of the MCP9800/1/2/3 silicon.
Contact Microchip for the latest Silicon fix.
1. Module: Device Internal latch up at
2. Module: POR active during oneshot
© 2007 Microchip Technology Inc.
The MCP9800/1/2/3 devices may latchup during
I
caused by the internal I
circuit.
At temperatures > 80°C (typically), High-to-Low
transition < 500 ns on the SDA or SCL lines
causes the slew control circuit to latchup.
Work around
Connect a capacitor accross the SDA and SCL
pull-up resistors so that the SDA and SCL fall time
is > 500 ns. For example, use 5 kΩ/0.01 µf.
Date Codes that pertain to this issue:
Not all production devices have these issues.
Contact the Microchip Regional Sales Office for
the fixed version.
At high temperature the MCP9800/1/2/3 may reset
while waking up from the oneshot Mode. All
registers may be set the power up default states.
Work around
Shutdown and wake the device using the Shut-
down bit in the configuration register.
Date Codes that pertain to this issue:
Not all production devices have these issues.
