Typical Applications

EP20K100CB356C7 is suitable for 6 applications: Telecom Line Card Interface, ASIC Prototyping Platform, Industrial Automation Controller, Networking Switch / Router Control Plane, Test and Measurement Instrumentation, Legacy Embedded Computing Board.

🌐

Telecom Line Card Interface

The EP20K100CB356C7's 100K gates and 252 user I/Os make it well suited to telecom line card glue logic, where it bridges TDM/E1 framers, crosspoint switches, and backplane SERDES. Its MultiVolt I/O supports 5V legacy framer ICs alongside 3.3V/2.5V processors in the same design, eliminating level shifters. The 53,248 bits of embedded array block memory buffer small packets and lookup tables without external SRAM. Four PLLs derive multiple clock domains for framer, network processor, and backplane sections, while 356-LBGA routability supports the high pin-out typical of telecom backplane designs.

🖥️

ASIC Prototyping Platform

The EP20K100CB356C7 is widely used as an ASIC prototyping vehicle because its 53,248 logic elements can emulate millions of ASIC gates when mapped 3:1 to 4:1. Designers partition ASIC RTL across multiple APEX20K FPGAs using JTAG-chained configuration and pin-multiplexed I/O. The 356-LBGA package exposes enough pins to break out wide internal buses for multi-FPGA emulation boards. Quartus II synthesis flows let teams validate ASIC RTL weeks before tape-out, catching architectural bugs at near-ASIC speed using the C7 speed grade.

🏭

Industrial Automation Controller

In factory-automation controllers the EP20K100CB356C7 provides deterministic logic for PLC scan engines, motion-control sequencers, and fieldbus protocol handling. Its 252 I/Os interface directly to 24V optically-isolated digital inputs and PWM motor driver outputs, while MultiVolt I/O simplifies mixed-voltage designs. Embedded array blocks store look-up tables for PID control loops and recipe data, reducing external memory accesses. The four PLLs generate synchronized PWM carriers for multi-axis drives, with the C7 speed grade comfortably meeting typical 50 µs scan times for 32-axis controllers.

🌐

Networking Switch / Router Control Plane

The EP20K100CB356C7 is well matched to networking switch and router control-plane designs where it implements forwarding table management, queue scheduling, and management interface glue logic. With 53,248 logic elements the device handles IPv4/v6 lookup tables and ACL matching in parallel pipelines. The 356-LBGA footprint exposes sufficient pins for management Ethernet MACs, PHY interfaces, and switch fabric status buses. JTAG in-system programmability enables field firmware updates without board removal, an essential feature for deployed networking gear.

🔧

Test and Measurement Instrumentation

Test equipment manufacturers use the EP20K100CB356C7 to implement stimulus generation, response capture, and timing sequencer logic in one device. The 100K gates accommodate deep sequencer ROM and DSP-style multiply-accumulate paths, while 53,248 bits of embedded memory buffer captured samples before DMA to host. MultiVolt I/O lets the FPGA directly drive 5V legacy measurement ADCs and 1.8V precision ADCs in the same instrument. Four PLLs synthesize precise sample clocks, and the 356-LBGA package provides enough I/O for parallel data acquisition across multiple channels.

✈️

Legacy Embedded Computing Board

The EP20K100CB356C7 anchors legacy VME and CompactPCI embedded computing boards, providing local bus arbitration, DMA engine control, and interrupt steering for PowerPC or MIPS host processors. Its 252 I/Os are enough to drive 32-bit local buses plus expansion headers, and 53,248 bits of embedded memory accelerate scatter-gather descriptor processing. MultiVolt I/O directly interfaces 5V VMEbus backplane signaling without external transceivers. JTAG support allows board-level boundary-scan testing during production and field diagnostics, a strong requirement for aerospace and defense embedded systems.

The EP20K100CB356C7 has limited stock with Heisener listing 5,936 pieces and etei listing 8,342 pieces as of the 2026-09-07 search. Stock is not deep because the APEX20K family has been in end-of-life migration for several years. Engineers sourcing this part should plan for possible multi-distributor buys to assemble the required volume.
What are the key specifications of EP20K100CB356C7 that engineers should know?
The EP20K100CB356C7 combines 100,000 typical gates, 53,248 maximum logic elements, 252 user I/Os, four PLLs, and 53,248 bits of embedded memory in a 356-LBGA package running at 2.5V core. According to Intel PSG datasheets for the APEX20K family, it supports MultiVolt I/O from 1.8V to 5V and JTAG-based in-system programming. This density makes it suitable for telecom line cards, ASIC prototyping, and embedded control.
What is a drop-in replacement for EP20K100CB356C7?
The best drop-in replacement for the EP20K100CB356C7 in the same 356-BGA footprint is the EP20K100CF324C8ES (note the package differs - 324-pin FineLine BGA). For true 356-BGA footprint compatibility, the EP20K100CB356-1 (which appears in the Site MPN list) is the same family with -1 speed grade, sharing the 356-BGA pinout. Both maintain APEX20K architecture and MultiVolt I/O for design continuity.
Can EP20K100CB356C7 be replaced by a Cyclone device?
The EP20K100CB356C7 cannot be a pin-for-pin drop-in replacement with any Cyclone device because the APEX20K BGA footprint is unique to that family. A Cyclone III EP3C40 or EP3C55 in a comparable BGA is functionally similar in logic capacity but requires PCB redesign and Quartus II re-synthesis. Treat migration as a porting exercise, not a drop-in swap.
Where to download EP20K100CB356C7 datasheet PDF?
The official APEX20K datasheet can be downloaded from Altera's legacy literature archive at https://www.altera.com/literature/ds/apex20k.pdf or via Intel PSG's 'Support' legacy section. The datasheet covers device architecture, electrical characteristics, pinout, JTAG programming, and Quartus II / MAX+PLUS II toolchain flow. Distributors also host mirrored PDFs on product detail pages such as Heisener and Veswin.
Where can I find the EP20K100CB356C7 pinout?
The EP20K100CB356C7 pinout for the 356-LBGA package is published in the official APEX20K datasheet at https://www.altera.com/literature/ds/apex20k.pdf, including JTAG pins (TCK, TMS, TDI, TDO), dedicated clock inputs, PLL supply pins, and the 252 user I/O assignments. Pin multiplexing follows the standard Altera BGA convention with banks grouped by I/O voltage for MultiVolt operation.
What software tools support the EP20K100CB356C7?
The EP20K100CB356C7 is supported by Altera Quartus II (legacy versions up to 13.0sp1) and MAX+PLUS II toolchains. Both provide logic synthesis, place-and-route, simulation, and JTAG programming flows. Newer Quartus Prime versions no longer support APEX20K devices; engineers should archive a Quartus II 13.0sp1 installation to maintain these designs.
EP20K100CB356C7 vs EP20K100CF324C8ES - which is better?
The EP20K100CB356C7 (356-LBGA, 252 I/O) and EP20K100CF324C8ES (324-FBGA, fewer I/O) are both APEX20K 100K-gate FPGAs but in different packages. Choose the CB356C7 when your PCB layout is fixed at 356-BGA and you need 252 I/Os; choose the CF324C8ES for new compact designs that can adopt the 324-pin FineLine BGA. They are not pin-compatible drop-ins, so a swap requires PCB redesign.
When should I choose EP20K100CB356C7 over a modern Cyclone FPGA?
Choose the EP20K100CB356C7 only when maintaining an existing APEX20K design where the 356-LBGA footprint and Quartus II toolchain are already validated in production. For new designs, prefer Cyclone III or Cyclone IV because they offer lower power, higher logic density per dollar, and active long-term support. The EP20K100CB356C7 remains useful for legacy spare-part inventory and EOL bridge orders.

Key Differentiators

  • Highest speed grade in the 356-LBGA APEX20K 100K-gate family (vs EP20K100CB356-1)
  • Best pin-count density in the 100K APEX20K family (vs EP20K100CF324C8ES)
  • Industrial-proven APEX20K architecture with MultiVolt I/O (vs EP20K1000CF672C7)

Design Notes

The EP20K100CB356C7 is in last-time-buy lifecycle. Plan a Cyclone III/IV or Stratix migration path before committing new production volumes; new designs should target active parts. If the design must remain on APEX20K, freeze the Quartus II 13.0sp1 toolchain version and archive the bitstreams because Quartus Prime no longer supports APEX20K.

The 356-LBGA package requires careful PCB stack-up design with controlled-impedance traces and a solid ground/power plane directly under the BGA. Use microvia or via-in-pad technology to fan out the 1.0 mm pitch BGA balls; standard 0.2 mm via-pads will not fit between BGA pads. Decouple every VCCINT and VCCIO pin with 0.1 µF and 10 µF capacitors placed within 5 mm of the package.

Estimated: at 2.5V core, typical APEX20K 100K-gate designs draw 0.5-1.5A depending on utilization and clock rate. With four PLL analog supplies at 2.5V each drawing 50 mA, total worst-case current is approximately 2A from a low-noise LDO. The VCCIO banks can draw separately at 1.8V/2.5V/3.3V/5V; size each bank regulator to handle peak I/O toggle current of 50 mA per pin pair.

MultiVolt I/O banks must each be powered by a separate regulator if mixing 1.8V/3.3V/5V signaling on the same FPGA. Tie unused I/O pins to logic-high or logic-low through Quartus II pin settings rather than leaving them floating - floating I/Os can draw shoot-through current and inject noise into adjacent banks. Use series 33Ω damping resistors on clock nets longer than 50 mm.
