Electrical and Thermal Characteristics

AC Electrical Characteristics
This section provides the AC electrical characteristics for the MPC755. After fabrication, functional parts
are sorted by maximum processor core frequency as shown in Section 4.2.1, “Clock AC Specifications,”
and tested for conformance to the AC specifications for that frequency. The processor core frequency is
determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0:3] signals. Parts are sold
by maximum processor core frequency; see Section 10, “Ordering Information.”

Notes:
1. Caution: The SYSCLK frequency and PLL_CFG[0:3] settings must be chosen such that the resulting SYSCLK (bus)
frequency, CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective maximum or minimum operating
frequencies. Refer to the PLL_CFG[0:3] signal description in Section 8.1, “PLL Configuration
,” for valid PLL_CFG[0:3]
settings.
2. Rise and fall times measurements are now specified in terms of slew rates, rather than time to account for selectable I/O bus
interface levels. The minimum slew rate of 1 V/ns is equivalent to a 2 ns maximum rise/fall time measured at 0.4 and 2.4 V
(OVDD = 3.3 V) or a rise/fall time of 1 ns measured at 0.4 and 1.8 V (OVDD = 2.5 V).
3. Timing is guaranteed by design and characterization.
4. This represents total input jitter—short term and long term combined—and is guaranteed by design.
5. Relock timing is guaranteed by design and characterization. PLL-relock time is the maximum amount of time required for PLL
lock after a stable VDD and SYSCLK are reached during the power-on reset sequence. This specification also applies when
the PLL has been disabled and subsequently re-enabled during sleep mode. Also note that HRESET must be held asserted
for a minimum of 255 bus clocks after the PLL-relock time during the power-on reset sequence.
