ELECTRICAL CHARACTERISTICS
Absolute Maximum Ratings [1]
1. Operation of the device at values in excess of those listed above will result in degradation or destruction of the device. All voltages
are dened with respect to ground. Functional operation of the device at these or any other conditions beyond those indicated under
“recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
effect device reliability.

2. The V
DD_CORE supplies voltage to the onboard DC-DC regulator. The onboard DC-DC regulator then powers the CPU core and the
SRAM I/O bus interface. The V
DD_CORE must be lower than VDD, except when the CPU is being re-cycled, at which time the VDD can
be lower than V
DD_CORE for 30 ms or less, provided that the current is limited to twice thew maximum CPU rating.
