Typical Applications
EP20K100FC324-2V is suitable for 6 applications: Telecommunications Line Cards, Network Switches and Routers, Industrial Control Systems, PCI / PCI-X Bridge Designs, DSP Pre-Processing Front-Ends, Legacy Sustaining / Last-Time-Buy Systems.
Telecommunications Line Cards
The EP20K100FC324-2V fits telecommunications line cards with its 100,000-gate capacity and 252 user I/Os. The MultiCore architecture combines LUT logic for register-intensive datapaths and product-term logic for fast combinatorial decode, enabling a single FPGA to handle protocol framing, DMA, and glue logic. The 167 MHz internal clock supports T1/E1 and early Ethernet framer rates, while 53,248 bits of embedded memory implement packet buffers and FIFO queues without external SRAM. The 324-FBGA 19x19 mm footprint keeps line-card density high.
Recommended
Network Switches and Routers
In network switches and routers, the EP20K100FC324-2V integrates bus arbitration, packet classification, and lookup-table engines. The 252 I/O count accommodates 32-bit data buses plus parity, control, and status signals without external muxing. Its 1.8 V LVDS-capable I/O pairs well with PHY devices of the era, and the embedded memory supports CAM/RAM-based routing tables. The APEX 20K MultiCore architecture allows designer to mix LUT and product-term regions for optimum area efficiency on mixed datapath-control designs.
Recommended
Industrial Control Systems
The EP20K100FC324-2V serves industrial control boards requiring deterministic logic, multiple sensor interfaces, and motor-control signal generation. With 252 I/Os, designers can directly interface to encoders, PWM generators, and parallel ADC/DAC converters without intermediate buffers. Product-term logic provides fast combinatorial response for safety-critical interlocks, while LUT logic handles state machines and DSP pre-processing. The 324-FBGA package supports ruggedized PCB designs with via-in-pad and 4-6 layer stack-ups.
Recommended
PCI / PCI-X Bridge Designs
Bridge designs from PCI to PCI-X, or PCI to legacy buses, benefit from the EP20K100FC324-2V's combination of register-rich logic and 252 I/Os. The 64-bit PCI-X bus at 66 MHz requires careful timing closure that the -2 speed grade supports comfortably. Embedded memory blocks implement transaction buffers and command queues. The MultiCore architecture lets the designer place PCI-X state machines in product-term logic for fast register-to-register timing and the data path in LUT logic for flexibility.
Recommended
DSP Pre-Processing Front-Ends
The EP20K100FC324-2V is suited to DSP pre-processing such as data formatting, gain control, and decimation filtering ahead of external DSP processors. Its 100K-gate capacity and 53,248 bits of embedded memory enable multi-channel data paths with coefficient storage on-chip. The 167 MHz performance supports sampling rates up to 80-100 MSPS after digital downconversion. Product-term logic handles fast comparator and threshold logic, while LUT logic implements FIR filter structures and address generators.
Recommended
Legacy Sustaining / Last-Time-Buy Systems
The EP20K100FC324-2V remains in demand for sustaining legacy systems where the FPGA is soldered onto long-life products (industrial, aerospace ground equipment, medical imaging). Rochester Electronics holds factory-traceable stock for these sustainment customers. The 324-FBGA footprint is fully shared with same-package -1 and non-V speed grades, giving designers flexibility to source from multiple last-time-buy channels. Designers planning new platforms should migrate to Cyclone IV/V or comparable families.

Key Differentiators
- Highest speed grade within 324-FBGA APEX 20K family (vs EP20K100FC324-1V)
- V-suffix grade offers tighter voltage/temperature screening (vs EP20K100FC324-2)
- Original APEX 20K (non-KE) silicon architecture (vs EP20K100EFC324-2X)
Design Notes
Estimated: at 167 MHz internal toggle rate with 50% I/O switching on a typical 252-I/O design, the EP20K100FC324-2V may dissipate 1.5-2.5 W. The 324-FBGA package requires a thermal pad with at least 4 thermal vias to inner ground planes. Designers should follow Altera's APEX 20K thermal management guideline and derate maximum junction temperature by 10C if operating above 80C ambient.
The 324-FBGA package at 1.0 mm ball pitch requires 4-6 layer PCB stack-up with microvia (laser-drilled) technology to fan out the inner rows. Use 0.5 mm drilled microvias with 1.0 mm pad, and ensure BGA pad finish is ENIG or OSP for reliable solder joint formation. Maintain 50 ohm controlled impedance on LVDS pairs routed from the FPGA per APEX 20KE layout guidelines.
APEX 20K uses 1.8 V core but JTAG/programming voltage follows the legacy 2.5 V or 3.3 V standard depending on board design. Do not mix APEX 20K (non-E) and APEX 20KE (with LVDS) silicon in the same design without verifying JTAG chain compatibility. Configuration via passive serial or JTAG requires a stable reference clock during power-up; allow 100 ms minimum before initiating configuration per Altera datasheet.
Compliance Information
EP20K100FC324-2V is a legacy Altera APEX 20K family part (pre-2006). Compliance certifications are not documented in modern distributor listings; refer to Altera/Intel FPGA legacy documentation for original material declarations. RoHS status uncertain due to legacy product age and last-time-buy distribution via aftermarket channels.
