Local Expansion Bus Controller
Overview
The Expansion bus controller provides an interface from to external Expansion target
devices.
The Expansion bus controller includes a 25-bit address bus and a 16-bit wide data path.
The expansion bus supports Intel multiplexed, Intel non-multiplexed, Intel
StrataFlash^® technology, Intel StrataFlash^® Synchronous Memory, Micron* Flow-
Through ZBT, Motorola* multiplexed, Motorola non-multiplexed, and Texas
Instruments* Host Port Interface (HPI) target devices.
Byte-wide devices may also be used by programming the channel connection for 8-bit
operation. For TI DSPs that support an internal bus width of 32 bits, the multiplexed
HPI-8 or HPI-16 interface can be used to complete these transfers.
Feature List
• Outbound transfers (the EP80579 integrated processor is the master to an external
target device).
• Eight programmable target chip selects.
• Twenty five bits of address; sixteen bits of data.
• Supports Intel mode and Motorola* mode bus cycles.
• Supports Intel StrataFlash^® technology.
• Supports 66-MHz Intel StrataFlash^® Synchronous Memory (16-bit only).
• Supports 16-bit Micron Flow-Through ZBT (Zero bus turnaround) SRAMS.
• Supports 8-bit and 16-bit Texas Instruments HPI specifications.
• Multiplexed or non-multiplexed address / data buses for Intel/Motorola*/HPI bus
cycles.
• Supports even and odd parity generation and calculation for Intel/Motorola*/
Micron* ZBT modes.
• Maximum clock input frequency of 80 MHz.
• Minimum input clock frequency of 33MHz.
