Switching Characteristics over Commercial and Industrial Operating Ranges
Ready and Peripheral Timing (25 MHz and 33 MHz)
Notes:
All timing parameters are measured at V
output test conditions are with C
a This timing must be met to guarantee proper operation.
b This timing must be met to guarantee recognition at the clock edge.
Switching Characteristics over Commercial and Industrial Operating Ranges
Ready and Peripheral Timing (40 MHz and 50 MHz)
Notes:
All timing parameters are measured at V
output test conditions are with C
a This timing must be met to guarantee proper operation.
b This timing must be met to guarantee recognition at the clock edge.
