5.4 Memory

5.4.1 DDR2 SDRAM

The dedicated DDR2 memory bus is 32 bits wide, single bank, 200MHz clock 
frequency, no ECC.  It uses the MPC5125 DDR2 SDRAM controller and is 
directly connection to the MPC5125.

5.4.2 NAND FLASH

Dedicated NAND FLASH memory is  directly connected to the MPC5125 

NFC 

NAND flash controller

.

The RTC_CLK_32.768Khz is used by the CPU's internal XTAL_RTC drive 
circuitry.
