XC7300 CMOS EPLD Family
Product Description
Features
Description
• High-performance Erasable Programmable Logic
Devices (EPLDs)
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.
– 5 / 7.5 ns pin-to-pin speeds on all fast inputs
– Up to 167 MHz maximum clock frequency
• Advanced Dual-Block architecture
– Fast 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.
– High-Density Function Blocks
(XC7354, XC7372, XC73108, XC73144)
• 100% interconnect matrix
• High-speed arithmetic carry network
– 1 ns ripple-carry delay per bit
– 43 to 61 MHz 18-bit accumulators
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.
• Multiple independent clocks
• Each input programmable as direct, latched, or
registered
• High-drive 24 mA output
• I/O operation at 3.3 V or 5 V
All XC7300 devices are designed in 0.8µ CMOS EPROM
technology.
• Meets JEDEC Standard (8-1A) for 3.3 V ±0.3 V
• Power management options
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-
• Multiple security bits for design protection
• Supported by industry standard design and verification
tools
• 100% PCI compliant
