1 Overview
This figure shows the major functional units within the MPC8308. The e300 core in the MPC8308, with
its 16 Kbytes of instruction and 16 Kbytes of data cache, implements the Power Architecture user
instruction set architecture and provides hardware and software debugging 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),
2
an integrated programmable interrupt controller (IPIC), a general purpose DMA controller, two I C
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.
This figure shows a block diagram of the device.

2 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.
2.1 Overall DC Electrical Characteristics
This section covers the ratings, conditions, and other characteristics.
