Description
The XC7300 family employs a unique Dual-Block architec-
ture, which provides high speed operations via Fast Func-
tion Blocks and/or high density capability via High Density
Function Blocks.
Fast Function Blocks (FFBs) provide fast, pin-to-pin
speed and logic throughput for critical decoding and ultra-
fast state machine applications. High-Density Function
Blocks (FBs) provide maximum logic density and system-
level features to implement complex functions with pre-
dictable timing for adders and accumulators, wide func-
tions and state machines requiring large numbers of
product terms, and other forms of complex logic.
In addition, the XC7300 architecture employs the Univer-
sal Interconnect Matrix (UIM) which guarantees 100%
interconnect of all internal functions. This interconnect
scheme provides constant, short interconnect delays for
all routing paths through the UIM. Constant interconnect
delays simplify device timing and guarantee design perfor-
mance, regardless of logic placement within the chip.
All XC7300 devices are designed in 0.8

technology.
All XC7300 EPLDs include programmable power manage-
ment features to specify high-performance or low-power
operation on an individual Macrocell-by-Macrocell basis.
Unused Macrocells are automatically turned off to mini-
