This document describes part-number-specific changes to recommended operating conditions
and revised electrical specifications, as applicable, from those described in the general
MPC7455 RISC Microprocessor Hardware Specifications (Order No. MPC7455EC). The
MPC7455 is a PowerPCTM microprocessor.

Specifications provided in this document supersede those in the MPC7455 RISC
Microprocessor Hardware Specifications, Rev. 0 or later, for the part numbers listed in
Table A only. Specifications not addressed herein are unchanged. Because this document is
frequently updated, refer to http://www.motorola.com/semiconductors or to your Motorola
sales office for the latest version.

Note that headings and table numbers in this document are not consecutively numbered. They
are intended to correspond to the heading or table affected in the general hardware
specification.

Part numbers addressed in this document are listed in Table A.

Note: The X prefix in a Motorola part number designates a "Pilot Production Prototype" as defined by
Motorola SOP 3-13. These are from a limited production volume of prototypes manufactured, tested,
and Q.A. inspected on a qualified technology to simulate normal production. These parts have only
preliminary reliability and characterization data. Before pilot production prototypes may be shipped,
written authorization from the customer must be on file in the applicable sales office acknowledging the
qualification status and the fact that product changes may still occur while shipping pilot production
prototypes.

Notes:
1. These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power (OV

and GV

) or PLL supply power (AV

). OV

and GV

power is system dependent, but is typically < 5% of V

power. Worst case power consumption for AV

< 3 mW.

2. Maximum power is measured at nominal V

while running an entirely cache-resident, contrived sequence of

instructions which keep the execution units, with or without AltiVec, maximally busy.

3. Typical power is an average value measured at nominal V

in a system while running a typical code sequence.

4. Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode.

As a result, power consumption for this mode is not tested.

All other outputs

L3CHOZ

L3_CLK

/4 + 2.0

L3_CLK

/4 + 2.0

Notes:

1. Rise and fall times for the L3_CLK output are measured from 20% to 80% of GV

2. For DDR, all input specifications are measured from the midpoint of the signal in question to the midpoint voltage

of the rising or falling edge of the input L3_ECHO_CLKn (see Figure 10 in the MPC7455 RISC Microprocessor
Hardware Specifications). Input timings are measured at the pins.

3. For DDR, the input data will typically follow the edge of L3_ECHO_CLKn as shown in Figure 10 in the MPC7455

RISC Microprocessor Hardware Specifications. For consistency with other input setup time specifications, this will
be treated as negative input setup time.

4. t

L3_ECHO_CLK

/4 is one-fourth the period of L3_ECHO_CLKn. This parameter indicates that the MPC7455 can latch

an input signal that is valid for only a short time before and a short time after the midpoint between the rising and
falling (or falling and rising) edges of L3_ECHO_CLKn at any frequency.

5. All output specifications are measured from the midpoint voltage of the rising (or for DDR write data, also the falling)

edge of L3_CLK to the midpoint of the signal in question. The output timings are measured at the pins. All output
timings assume a purely resistive 50-

load (see Figure 8 in the MPC7455 RISC Microprocessor Hardware

Specifications).

6. For DDR, the output data will typically lead the edge of L3_CLKn as shown in Figure 10 in the MPC7455 RISC

Microprocessor Hardware Specifications. For consistency with other output valid time specifications, this will be
treated as negative output valid time.

7. t

L3_CLK

/4 is one-fourth the period of L3_CLKn. This parameter indicates that the specified output signal is actually

launched by an internal clock delayed in phase by 90°. Therefore, there is a frequency component to the output valid
and output hold times such that the specified output signal will be valid for approximately one L3_CLK period
starting three-fourths of a clock prior to the edge on which the SRAM will sample it and ending one-fourth of a clock
period after the edge it will be sampled.

8. These configuration bits allow the AC timing of the L3 interface to be altered via software. They must be both set or

both cleared; other configurations will increase t

L3CSKW1

, which may cause unreliable L3 operation.

MOTOROLA

MPC7455 Part Number Specification for the XPC74x5RXnnnNx Series

General Parameters

1.9.1 PLL Configuration

The MPC7455 PLL is configured by the PLL_CFG[0:4] signals; note that PLL_CFG[4] was formerly called
PLL_EXT in earlier documentation. For a given SYSCLK (bus) frequency, the PLL configuration signals
set the internal CPU and VCO frequency of operation. PLL_CFG[4] will normally be pulled low but can be
asserted for extended modes of operation. The PLL configuration for the MPC7455 is shown in Table 17
for a set of example frequencies. In this example, shaded cells represent settings that, for a given SYSCLK
frequency, result in core and/or VCO frequencies that do not comply with the 1-GHz column in Table 8.
Note that the settings for Rev. C devices are different than those for subsequent devices.
