Clocking
Table 57 provides the operating frequencies for the MPC8349EA TBGA under recommended operating
conditions (see Table 2).
All frequency combinations shown in the table below may not be available. Maximum operating
frequencies depend on the part ordered, see Section 22.1, “Part Numbers Fully Addressed by This
Document,” for part ordering details and contact your Freescale Sales Representative or authorized
distributor for more information.
19.1
System PLL Configuration
The system PLL is controlled by the RCWL[SPMF] parameter. Table 58 shows the multiplication factor
encodings for the system PLL.
Table 57. Operating Frequencies for TBGA
Characteristic1
1 The CLKIN frequency, RCWL[SPMF], and RCWL[COREPLL] settings must be chosen so that the resulting csb_clk, MCK,
LCLK[0:2], and core_clk frequencies do not exceed their respective maximum or minimum operating frequencies. The value of
SCCR[ENCCM], SCCR[USBDRCM] and SCCR[USBMPHCM] must be programmed so that the maximum internal operating
frequency of the security core and USB modules does not exceed the respective values listed in this table.

Local bus frequency (LCLKn)4
4 The local bus frequency is 1/2, 1/4, or 1/8 of the lbiu_clk frequency (depending on LCCR[CLKDIV]) which is in turn 1x or 2x the
csb_clk frequency (depending on RCWL[LBIUCM]).
