support. In addition, the MPC8308 offers a PCI Express controller, two three-speed 10, 100, 1000 Mbps

Ethernet controllers (eTSEC), a DDR2 SDRAM memory controller, a SerDes block, an enhanced local

bus controller (eLBC), an integrated programmable interrupt controller (IPIC), a general purpose DMA

controller, two I2C controllers, dual UART (DUART), GPIOs, USB, general purpose timers, and an SPI

controller. The high level of integration in the MPC8308 helps simplify board design and offers significant

bandwidth and performance.

A block diagram of the device is shown in Figure 1.

Electrical Characteristics

This section provides the AC and DC electrical specifications and thermal characteristics for the

MPC8308. The device is currently targeted to these specifications. Some of these specifications are

independent of the I/O cell, but are included for a more complete reference. These are not purely I/O buffer

design specifications.
