MPC8240 Part Number Specification for the XPC8240RXXnnnx Series
5
Ordering Information
Notes:
1. The processor HID1 values only represent the multiplier of the processor’s PLL (memory-to-processor multiplier);
thus, multiple MPC8240 PLL_CFG[0:4] values may have the same processor HID1 value. This implies that system
software cannot read the HID1 register and associate it with a unique PLL_CFG[0:4] value.
2. PLL_CFG[0:4] settings not listed (00110, 01001, 01011, 01101, 01111, 10001, 10011, 10101, 10111, 11001, and
11011) are reserved.
3. In PLL bypass mode, the PCI_SYNC_IN input signal clocks the internal processor directly, the peripheral logic PLL
is disabled, and the bus mode is set for 1:1 (PCI:Mem) mode operation. This mode is intended for hardware modeling
support. The AC timing specifications given in this document do not apply in PLL bypass mode.
4. In clock-off mode, no clocking occurs inside the MPC8240 regardless of the PCI_SYNC_IN input.
5. Limited due to maximum memory VCO = 225 MHz.
6. Limited due to minimum CPU VCO = 200 MHz.
7. Limited due to minimum memory VCO = 100 MHz.
8. For clarity, range values are shown rounded down to the nearest whole number (decimal place accuracy removed).
9. Note that the 250-MHz part is available only in the XPC8240RZUnnnx number series.
