Board-Level Functions
voltage regulator. VREF, which is half the interface voltage, or 0.9 V, is provided by a voltage divider of
1.8 V for voltage tracking and low cost. The MPC8313E provides a pair of clock pins, which are connected
and shared by the two DDR2 devices.

The MPC8313E local bus controller has a 26-bit LAD[0–15] and LA[16–25] address that consists of
16-bit data multiplex bus and control signals. The local bus speed is up to 133 MHz. To interface with the
standard memory device, an address latch must provide the address signals. The LALE is used as the
latching signal. To reduce loading of the high speed local bus interface, a data buffer for all low-speed
devices is attached to the memory controller. The followings modules are connected to the local bus:

Through the general-purpose chip-select machine (GPCM), the MPC8313E RDB provides 8 Mbyte of
flash memory using a chip-select signal. The flash memory is used with the 16-bit port size.
