Notes
1
DDR memories typically have a minimum speed specification of 83 MHz. Check memory component specifications to verify.
The frequency of operation is 2x or 4x the CLKIN frequency of operation. The MCF547X supports a single external
reference clock (CLKIN). This signal defines the frequency of operation for FlexBus and PCI, but SDRAM clock operates at
the same frequency as the internal bus clock. Please see the reset configuration signals description in the “Signal
Descriptions” chapter within the MCF547x Reference Manual.
3
SDCLK is one memory clock in (ns).
4
Pulse width high plus pulse width low cannot exceed max clock period.
5 Pulse width high plus pulse width low cannot exceed max clock period.
6 Command output valid should be 1/2 the memory bus clock (SDCLK) plus some minor adjustments for process,
temperature, and voltage variations.
7 This specification relates to the required input setup time of today’s DDR memories. SDDATA[31:24] is relative to SDDQS3,
SDDATA[23:16] is relative to SDDQS2, SDDATA[15:8] is relative to SDDQS1, and SDDATA[7:0] is relative SDDQS0.
8 The first data beat is valid before the first rising edge of SDDQS and after the SDDQS write preamble. The remaining data
beats is valid for each subsequent SDDQS edge.
9 This specification relates to the required hold time of today’s DDR memories. SDDATA[31:24] is relative to SDDQS3,
SDDATA[23:16] is relative to SDDQS2, SDDATA[15:8] is relative to SDDQS1, and SDDATA[7:0] is relative SDDQS0.
10 Data input skew is derived from each SDDQS clock edge. It begins with a SDDQS transition and ends when the last data
line becomes valid. This input skew must include DDR memory output skew and system level board skew (due to routing
or other factors).
11 Data input hold is derived from each SDDQS clock edge. It begins with a SDDQS transition and ends when the first data
line becomes invalid.

Please see the reset configuration signals description in the “Signal Descriptions” chapter within the MCF547x
Reference Manual. Also specific guidelines may need to be followed when operating the system PLL below certain
frequencies.
Max cycle rate is determined by CLKIN and how the user has the system PLL configured.
All signals defined as PCI bused signals. Does not include PTP (point-to-point) signals.
PCI 2.2 spec does not require an output hold time. Although the MCF547X may provide a slight amount of hold, it
is not required or guaranteed.
PCI 2.2 spec requires zero input hold.
These signals are defined at PTP (Point-to-point) in the PCI 2.2 spec.

MII/7-WIRE Interface Timing Specs
The following timing specs are defined at the chip I/O pin and must be translated appropriately to arrive at timing
specs/constraints for the EMAC_10_100 I/O signals.
The following timing specs meet the requirements for MII and 7-Wire style interfaces for a range of transceiver devices. If this
interface is to be used with a specific transceiver device the timing specs may be altered to match that specific transceiver.

JTAG and Boundary Scan Timing
1
Output numbers depend on the value programmed into the IFDR; an IFDR programmed with the
maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 21. The
I2C interface is designed to scale the actual data transition time to move it to the middle of the
SCL low period. The actual position is affected by the prescale and division values programmed
into the IFDR; however, the numbers given in Table 21 are minimum values.
2
Because SCL and SDA are open-collector-type outputs, which the processor can only actively
drive low, the time SCL or SDA take to reach a high level depends on external signal capacitance
and pull-up resistor values.
