2. Maximum power is the maximum measured at nominal V

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

running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz.
4. Doze mode is not a user-denable 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 specications are measured from the midpoint of the signal in question to the midpoint of the rising edge
of the input SYSCLK. All output specications 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-
load (see Figure 4 in the
MPC7457 RISC Microprocessor Hardware Specifications)
. Input and output timings are measured at the pin;
time-of-ight delays must be added for trace lengths, vias, and connectors in the system.
2. The symbology used f or timing specications herein follo ws the pattern of t
(signal)(state)(reference)(state)
f or inputs and
t
(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
×
t
SYSCLK
, that is, less than the minimum
t
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 rst 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 rst 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 congurations).
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.
