General
Description
Altera’s Flexible Logic Element MatriX (FLEX®) family combines the
benefits of both erasable programmable logic devices (EPLDs) and field-
programmable gate arrays (FPGAs). The FLEX 8000 device family is ideal
for a variety of applications because it combines the fine-grained
architecture and high register count characteristics of FPGAs with the
high speed and predictable interconnect delays of EPLDs. Logic is
implemented in LEs that include compact 4-input look-up tables (LUTs)
and programmable registers. High performance is provided by a fast,
continuous network of routing resources.

FLEX 8000 Programmable Logic Device Family Data Sheet
FLEX 8000 devices provide a large number of storage elements for
applications such as digital signal processing (DSP), wide-data-path
manipulation, and data transformation. These devices are an excellent
choice for bus interfaces, TTL integration, coprocessor functions, and
high-speed controllers. The high-pin-count packages can integrate
multiple 32-bit buses into a single device. Table 3 shows FLEX 8000
performance and LE requirements for typical applications.

All FLEX 8000 device packages provide four dedicated inputs for
synchronous control signals with large fan-outs. Each I/O pin has an
associated register on the periphery of the device. As outputs, these
registers provide fast clock-to-output times; as inputs, they offer quick
setup times.
The logic and interconnections in the FLEX 8000 architecture are
configured with CMOS SRAM elements. FLEX 8000 devices are
configured at system power-up with data stored in an industry-standard
parallel EPROM or an Altera serial configuration devices, or with data
provided by a system controller. Altera offers the EPC1, EPC1213,
EPC1064, and EPC1441 configuration devices, which configure
FLEX 8000 devices via a serial data stream. Configuration data can also be
stored in an industry-standard 32 K × 8 bit or larger configuration device,
or downloaded from system RAM. After a FLEX 8000 device has been
configured, it can be reconfigured in-circuit by resetting the device and
loading new data. Because reconfiguration requires less than 100 ms, real-
time changes can be made during system operation. For information on
how to configure FLEX 8000 devices, go to the following documents:
