Electrical Characteristics

DMA Controller, I2C, DUART, Enhanced Local Bus Controller
(eLBC), and Timers
The integrated four-channel DMA controller includes the following features:
Allows chaining (both extended and direct) through local memory-mapped chain descriptors
(accessible by local masters)
Misaligned transfer capability for source/destination address
Supports external DREQ, DACK and DONE signals
There is one I2C controller. This synchronous, multi-master buses can be connected to additional devices
for expansion and system development.
The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550
programming models. 16-byte FIFOs are supported for both the transmitter and the receiver.
The eLBC port allows connections with a wide variety of external DSPs and ASICs. Three separate state
machines share the same external pins and can be programmed separately to access different types of
devices. The general-purpose chip select machine (GPCM) controls accesses to asynchronous devices
using a simple handshake protocol. The three user programmable machines (UPMs) can be programmed
to interface to synchronous devices or custom ASIC interfaces. Each chip select can be configured so that
the associated chip interface can be controlled by the GPCM or UPM controller. Both may exist in the
same system. The local bus can operate at up to 66 MHz.
The system timers include the following features: periodic interrupt timer, real time clock, software
watchdog timer, and two general-purpose timer blocks.

Electrical Characteristics
This section provides the AC and DC electrical specifications and thermal characteristics for the
MPC8314E, which is currently targeted to these specifications. Some of these specifications are
independent of the I/O cell, but they are included for complete reference. These are not purely I/O buffer
design specifications.
