EPC40C100 - Altera Enhanced Configuration Device, 40-Mbit | Intel FPGA
MPN： EPC40C100 ✗ 停產EPC40C100 概覽
An Enhanced Configuration Device is a member of the configuration-memory family that sits between simple serial EEPROMs and processor-based boot schemes. Its hierarchy is: configuration memory -> non-volatile boot memory -> FPGA support IC. Compared to legacy EPC16/EPC8 parts, the EPC40C100 quadruples density (40 Mbit vs 16 Mbit) and adds features such as multi-page programming, page-mode read acceleration, and built-in CRC error detection, enabling rapid, reliable multi-FPGA cascade configuration.
Key features include 40-Mbit flash storage organized in pages, a 66 MHz parallel configuration interface, 2.5V/3.3V multi-voltage I/O, in-system programmability via JTAG, and dedicated configuration-clock output. The device supports continuous read, burst-mode page read, and byte-level programming, giving designers flexible boot-loader behavior. Built-in CRC checking ensures bitstream integrity, reducing the risk of corrupted FPGA configuration in safety-critical systems.
Architecturally, the EPC40C100 integrates a 40-Mbit NOR flash array with a serial-peripheral-interface (SPI) compatible controller, an IEEE 1149.1 JTAG tap for ISP, and dedicated FPP (Fast Passive Parallel) configuration logic. The flash page architecture supports random-access reads while sustaining 66 MHz FPP throughput, shortening FPGA configuration time for high-density Stratix devices.
Typical applications include single-FPGA boot configuration in industrial controllers, multi-FPGA cascade configuration for DSP and ASIC prototyping, factory-floor programmable logic controllers, and test-and-measurement equipment requiring rapid secure boot. The 40-Mbit density suits Stratix II/III and large Cyclone families that exceed the capacity of EPC16.
When designing with this part, note that the 100-pin EQFP package requires a 4-layer PCB with solid ground plane and 0.5 mm pitch fan-out. Configure the target FPGA's MSEL pins for FPP mode and provide a clean 2.5V or 3.3V supply; in-system programming via JTAG requires 4 dedicated pins that must be reserved in the PCB layout.

典型應用
EPC40C100 適用於 6 應用s: Single-FPGA Boot in Industrial Controllers, Multi-FPGA Cascade Configuration, Test and Measurement Equipment, Military and Aerospace Avionics, Networking and Communications Line Cards, Medical Imaging and Diagnostic Equipment.
Single-FPGA Boot in Industrial Controllers
The EPC40C100 stores the configuration bitstream for a single SRAM-based LUT FPGA such as a Stratix II or Cyclone III in factory-floor PLC and motor-control systems. Its 40-Mbit density fits Stratix II EP2S60/EP2S90 bitstreams which exceed the 16-Mbit capacity of EPC16. The 66 MHz FPP mode shortens configuration time below 100 ms - critical for safety interlocks that demand fast system ready states. The built-in CRC verification confirms bitstream integrity before enabling the FPGA's CONF_DONE output, preventing partial-configuration faults on power-up. Industrial designers value the -40C to +85C operating range which matches IEC 60068-2 environmental requirements.
推薦
Multi-FPGA Cascade Configuration
In high-throughput DSP and ASIC prototyping platforms, multiple FPGAs are loaded in daisy-chain from a single configuration source. The EPC40C100 supports Altera's multi-device cascade protocol via its nCASC pin, streaming the bitstream to a primary FPGA that then forwards it to secondary FPGAs. The 40-Mbit density is sufficient to load three or four medium-density Cyclone III FPGAs sharing one configuration source. Page-mode read accelerates the cascade by prefetching subsequent pages during the active configuration cycle. The JTAG ISP interface allows field reconfiguration of the entire chain without removing any device from the PCB.
推薦
Test and Measurement Equipment
Bench-top instruments such as logic analyzers, protocol testers, and signal generators use SRAM-based FPGAs that must boot rapidly and reliably each time the instrument is power-cycled. The EPC40C100 delivers a 40-Mbit non-volatile bitstream repository with sub-100 ms FPP boot, minimizing instrument warm-up time. Built-in CRC error detection prevents field returns caused by corrupted configuration. The JTAG ISP enables firmware updates via USB-to-JTAG bridges from a host PC. The industrial -40C to +85C temperature range supports outdoor or ruggedized test equipment deployed in telecom and aerospace maintenance.
推薦
Military and Aerospace Avionics
Avionics subsystems and ruggedized military embedded systems rely on SRAM FPGAs with deterministic cold-start configuration. The EPC40C100's industrial temperature range and built-in CRC verification support DO-254 design-assurance workflows where configuration integrity is auditable. The 100-pin EQFP package provides robust mechanical bonds for vibration-prone airframes. Multi-page read shortens boot time to meet mission-computer ready-state deadlines. The JTAG ISP interface supports depot-level firmware updates between deployment cycles without desoldering the device.
推薦
Networking and Communications Line Cards
High-density packet processors and network line cards use SRAM FPGAs as co-processors for traffic classification and encryption. The EPC40C100 provides a 40-Mbit boot repository that fits large Cyclone III or Stratix II designs with multiple soft-core Nios CPUs. The 66 MHz FPP throughput ensures the FPGA enters operational state during the line card's 200 ms power-on window. Multi-voltage 2.5V/3.3V I/O integrates seamlessly with legacy ASIC buses. Built-in CRC eliminates silent corruption that would otherwise pass basic POST checks.
推薦
Medical Imaging and Diagnostic Equipment
Ultrasound carts, MRI gradient controllers, and patient monitors use SRAM FPGAs for real-time signal processing where deterministic boot is safety-relevant. The EPC40C100 supplies a 40-Mbit bitstream with sub-100 ms configuration and built-in CRC verification that confirms integrity before the FPGA enters user mode. The industrial -40C to +85C operating range supports continuous-operation medical equipment that runs 24/7 in clinical environments. The JTAG ISP allows field firmware updates during scheduled maintenance windows without disassembling the device, supporting IEC 62304 software lifecycle requirements.

主要差異化特點
- 2.5x higher memory density than EPC16 family (對比EPC16QC100)
- Drop-in package compatibility with EPC16 family (對比EPC16UC88)
- Higher FPP clock margin than EPC16 variants (對比EPC16QI100)
設計說明
The EPC40C100 uses a 100-pin Enhanced Quad Flat Pack with 0.5 mm pitch. Fan-out requires a 4-layer PCB with 4-mil traces and 8-mil spaces. Place the device within 50 mm of the target FPGA to keep the 66 MHz FPP clock traces short and matched (within 1 mm). Use a continuous ground plane under the package to control impedance and provide a thermal path. Add 0.1 uF decoupling capacitors on every VCC pin plus a single 10 uF bulk capacitor near the supply entry.
Set the target FPGA's MSEL pins to match the configuration mode (FPP or PS) used by the EPC40C100 - mismatched MSEL settings cause CONF_DONE to never assert. Connect nSTATUS, CONF_DONE, nCONFIG, and DCLK between the EPC40C100 and the FPGA in a point-to-point topology without stubs. When cascading multiple FPGAs, wire the nCASC pin of the EPC40C100 to the nCONFIG of the secondary FPGA and ensure all configuration clocks share a single source.
Reserve the four JTAG pins (TCK, TMS, TDI, TDO) on a header or test-point cluster for in-system programming access. Place a JTAG chain-header within 25 mm of the EPC40C100 package and provide 10 kohm pull-ups on TCK, TMS, and TDI per the IEEE 1149.1 specification. If the EPC40C100 shares the JTAG chain with the target FPGA, include the JTAG chain topology in the BSDL files for boundary-scan test.
