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

). O V

and GV

power is system dependent, b ut is typically <5%

of V

power. Worst case power consumption for AV

< 3 mW.

2. Maximum power is the maximum measured at nominal V

and maximum operating junction temperature (see

Table 4) while running an entirely cache-resident, contrived sequence of instructions which keep all the e xecution

units maximally busy.

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

(see Table 4) and 65

C while

running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz.

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.

Notes:

1. All input speciﬁcations are measured from the midpoint of the signal in question to the midpoint of the rising edge

of the input SYSCLK. All output speciﬁcations are measured from the midpoint of the rising edge of SYSCLK to the

midpoint of the signal in question. All output timings assume a purely resistive 50-

Ω

load (see Figure 4 in the

MPC7457 RISC Microprocessor Hardware Speciﬁcations)

. Input and output timings are measured at the pin;

time-of-ﬂight delays must be added for trace lengths, vias, and connectors in the system.

2. The symbology used f or timing speciﬁcations herein follo ws the pattern of t

(signal)(state)(reference)(state)

f or inputs and

(reference)(state)(signal)(state)

f or outputs. For e xample , t

IVKH

symbolizes the time input signals (I) reach the v alid state

(V) relative to the SYSCLK reference (K) going to the high (H) state or input setup time. And t

KHOV

symbolizes the

time from SYSCLK(K) going high (H) until outputs (O) are valid (V) or output v alid time. Input hold time can be read

as the time that the input signal (I) went invalid (X) with respect to the rising clock edge (KH) (note the position of

the ref erence and its state for inputs) and output hold time can be read as the time from the rising edge (KH) until

the output went invalid (OX).

3. t

SYSCLK

is the period of the external clock (SYSCLK) in ns. The numbers given in the table must be multiplied by

the period of SYSCLK to compute the actual time duration (in ns) of the parameter in question.

4. According to the bus protocol, TS is driven only by the currently active bus master. It is asserted low then

precharged high bef ore returning to high impedance, as shown in Figure 6 in the

MPC7457 RISC Microprocessor

Hardware Speciﬁcations

. The nominal precharge width for TS is 0.5

SYSCLK

, that is, less than the minimum

SYSCLK

period, to ensure that another master asserting TS on the following clock will not contend with the

precharge. Output valid and output hold timing is tested for the signal asserted. Output valid time is tested for

precharge. The high-impedance behavior is guaranteed by design.

5. Guaranteed by design and not tested.

6. According to the bus protocol, AR TRY can be driven by m ultiple bus masters through the cloc k period immediately

following AACK. Bus contention is not an issue because any master asserting ARTRY will be driving it low. Any

master asserting it low in the ﬁrst clock following AACK will then go to high impedance for one clock before

precharging it high during the second cycle after the assertion of AACK. The nominal precharge width for ARTRY

is 1.0 t

SYSCLK

; that is, it should be high impedance, as shown in Figure 6 in the

MPC7457 RISC Microprocessor

Hardware Speciﬁcations,

before the ﬁrst opportunity for another master to assert ARTRY. Output valid and output

hold timing is tested for the signal asserted.The high-impedance behavior is guaranteed by design.

7. According to the MPX bus protocol, SHD0 and SHD1 can be driv en by m ultiple bus masters beginning the cycle of

TS. Timing is the same as ARTRY, that is, the signal is high impedance for a fraction of a cycle, then negated for

up to an entire cycle (crossing a bus cycle boundary) before being three-stated again. The nominal precharge width

for SHD0 and SHD1 is 1.0 t

SYSCLK

. The edges of the precharge vary depending on the programmed ratio of core

to bus (PLL conﬁgurations).

8. BMODE[0:1] and BVSEL are mode select inputs and are sampled before and after HRESET negation. These

parameters represent the input setup and hold times f or each sample. These v alues are guaranteed b y design and

not tested. These inputs must remain stable after the second sample. See Figure 5 in the

MPC7457 RISC

Microprocessor Hardware Speciﬁcations

for sample timing.
