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 (OV
DD
= 3.3 V) or a rise/fall time
of 1 ns measured at 0.4 and 1.8 V (OV
DD
= 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 V
DD
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.
