EP20K100CF144C8 Visão geral
A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to configure digital logic circuits after manufacturing. The APEX-20K family belongs to the broader hierarchy of programmable logic devices (PLDs), which also includes complex PLDs (CPLDs). Within Intel's portfolio, FPGAs are categorized under Programmable Logic Devices (PLDs) > FPGAs. APEX-20K devices pioneered the MultiCore architecture that combines fine-grained logic and coarse-grained memory, making them well suited for system-on-chip (SoC) prototyping, DSP functions, and high-speed data-path designs.
Key features include 100K typical gates, 4,160 logic elements, 53,248 RAM bits distributed across embedded array blocks, 260 maximum I/O pins (part-specific to this device is 93 user I/Os in the 144-LQFP package), and a speed grade of -8 (commercial, mid-range). The device supports in-system programmability (ISP) via IEEE 1149.1 JTAG and offers 3.3V and 5.0V PCI compliance. The 144-LQFP package is a plastic surface-mount variant with 1.0 mm pitch and body size 20x20 mm, suitable for prototyping and low-to-medium volume production.
The architecture combines four types of logic resources: logic array blocks (LABs) for combinatorial and sequential logic, embedded system blocks (ESBs) for dual-port RAM, ROM, and CAM functions, fast-track interconnect for high-speed routing between rows and columns, and a network of embedded array blocks (EABs) for memory-intensive operations. This heterogeneous structure enables efficient implementation of both logic-heavy and memory-heavy designs on a single device, eliminating the need for external memory in many applications.
Typical applications include telecommunications equipment, industrial automation controllers, ASIC prototyping, high-speed digital signal processing (DSP), PCI bus interfaces, and embedded control systems. The 144-LQFP package and 93 user I/Os make it well suited for designs that need to bring out numerous signals for boundary-scan testing, external memory interfaces, or multi-channel I/O.
When designing with this device, ensure your board layout provides adequate decoupling (100 nF high-frequency ceramic and bulk tantalum or aluminum electrolytic capacitors) near each supply pin. Use the JTAG interface for ISP programming to support field upgrades. Plan I/O assignments early because the 144-LQFP package limits the package-out versus ball-grid options of larger APEX-20K devices.

Aplicações típicas
EP20K100CF144C8 é adequado para 6 aplicaçãos: Telecommunications Equipment, ASIC Prototyping and Emulation, Industrial Automation and Motor Control, PCI Bus Interface Bridge, DSP Pre/Post-Processing Front-End, Legacy Embedded Control and Custom Peripherals.
Telecommunications Equipment
The EP20K100CF144C8 fits telecom equipment such as base-station controllers, line-card interfaces, and protocol converters because its 4,160 logic elements and 53 Kbits of embedded dual-port RAM can implement channelized data paths, framing, and CRC engines without external SRAM. The 93 user I/Os are sufficient for parallel backplane buses (UTOPIA, H.110, or proprietary LVDS) and the -8 speed grade supports PCI 33/66 MHz for fabric interconnect. The JTAG 1149.1 ISP enables remote configuration across geographically distributed chassis. The 144-LQFP's moderate 1.0 mm pitch is still hand-solderable for low-volume OEM repair scenarios typical of legacy telecom infrastructure.
Recomendado
ASIC Prototyping and Emulation
The EP20K100CF144C8 is widely deployed in ASIC prototyping because 100K system gates approximates mid-complexity ASIC partitions, and Quartus synthesis tools support seamless migration from Altera APEX-20K to ASIC libraries. Embedded system blocks (ESBs) provide dual-port RAM that emulates on-chip SRAM buses, and the 144-LQFP package simplifies rework on prototype boards. Engineers typically use multiple EP20K100CF144C8 devices in a multi-FPGA partition for ASICs of up to ~400K gates. The -8 speed grade is sufficient for 100 MHz ASIC clock domains commonly used in prototyping of networking ASICs.
Recomendado
Industrial Automation and Motor Control
The EP20K100CF144C8 supports industrial PLC, motion controller, and machine-vision front-end applications where 100K gates is sufficient for combinational control logic, PWM generation, and encoder interface glue. The 93 user I/Os can fan out to 24V-tolerant opto-isolated field buses via external level shifters, and the 5V-tolerant I/Os can interface directly to legacy industrial sensors. Hardware multipliers in the ESBs accelerate fixed-point arithmetic for PID loops. The commercial 0C to +85C operating range covers most factory-floor environments; for harsher environments an industrial-grade variant would be required.
Recomendado
PCI Bus Interface Bridge
The EP20K100CF144C8 is certified 3.3V and 5.0V PCI-compliant per the PCI Local Bus Specification, making it ideal for implementing custom PCI target or initiator cores, PCI-to-local-bus bridges, and embedded host adapters. Its 93 user I/Os cover the 49-pin PCI bus plus local-side data, address, and control signals, while the 4,160 logic elements support 32-bit/33 MHz PCI state machines with DMA engines. The JTAG interface enables production-line PCI compliance testing. This was a flagship use case for APEX-20K devices in the early 2000s and remains relevant for legacy industrial PCI cards.
Recomendado
DSP Pre/Post-Processing Front-End
The EP20K100CF144C8 fits as a DSP co-processor front-end in audio/video processing pipelines, where it can implement FIR filters, FFT pre-processing, format conversion, and sample-rate conversion between dedicated DSPs and ADCs/DACs. The ESB embedded RAM blocks serve as data buffers and coefficient stores, and the 4,160 logic elements handle address generation and pipeline control. With 93 user I/Os, the device can connect to parallel video buses (e.g., BT.656) or multi-channel audio serial streams (I2S, TDM). The -8 speed grade supports video line-rate processing up to ~100 MHz pixel clocks.
Recomendado
Legacy Embedded Control and Custom Peripherals
The EP20K100CF144C8 is well-suited for legacy embedded control applications such as custom microcontroller peripherals, bus monitors, and instrumentation glue logic. Engineers often use the APEX-20K MultiCore architecture to consolidate multiple discrete CPLDs and PALs into a single device, simplifying board layout and reducing BOM cost. The 93 user I/Os can replace several 84-pin PLCC CPLDs while adding embedded RAM for buffering and JTAG ISP for in-field firmware updates. The 144-LQFP package is hand-solderable for prototyping.

Notas de projeto
The EP20K100CF144C8 requires two separate supply rails: VCCINT (2.5V core) and VCCIO (3.3V or 5V tolerant I/O). Place one 100 nF X7R ceramic decoupling capacitor as close as physically possible to every VCCINT and VCCIO pin, and add bulk 10 uF-47 uF tantalum or aluminum electrolytic capacitors near each supply plane. Decoupling VCCINT and VCCIO planes separately prevents I/O switching noise from coupling into the core logic, which can otherwise corrupt internal logic-element storage bits and create soft errors in configuration RAM during JTAG configuration.
The 144-LQFP package has 1.0 mm pitch and requires surface-mount soldering. For prototype boards, hand-soldering is feasible with a fine-tip soldering iron and 0.4 mm solder wire, but for production use reflow soldering with a profile reaching 220C-230C peak temperature is mandatory. Keep high-speed signal traces short and avoid 90-degree bends. Place a 4-layer PCB stack-up with dedicated ground and power planes; the APEX-20K MultiCore interconnect relies on continuous ground reference for impedance-controlled signal integrity, particularly on clock and JTAG signals.
Several configuration pitfalls affect the EP20K100CF144C8. First, nCONFIG must be held low during power-up and then released; if the JTAG controller is in test mode at power-up, configuration will be blocked. Second, the MSEL0/MSEL1 pins must be tied to known logic levels (typically GND for AS mode or VCC for PS mode) before power-up; floating MSEL pins can cause configuration errors. Third, the CONF_DONE pin is open-drain and requires an external pull-up to VCCIO. Finally, the JTAG chain must include proper TCK termination; long JTAG cables (>150 mm) without series damping resistors can cause signal integrity issues during ISP programming.
Place the JTAG connector at the board edge for test probe access. The TCK signal should be buffered near the connector to prevent ringing; a 33 ohm series resistor placed within 25 mm of the TCK pin is recommended. Use a star-routing topology from the JTAG connector to all EP20K100CF144C8 devices on the board, never a daisy chain, because the APEX-20K JTAG TAP controller does not have bypass-mode buffering equivalent to modern Cyclone devices. Ensure the JTAG chain length (sum of all TCK trace lengths) does not exceed 250 mm to maintain signal integrity at 10 MHz TCK.
Differential pair routing on EP20K100CF144C8 supports LVDS and PCI signaling. For 66 MHz PCI operation, maintain 65 ohm differential impedance and 50 ohm single-ended impedance on the PCI bus traces. Series termination resistors (33 ohm) should be placed within 25 mm of the FPGA transmit pin. For 33 MHz PCI, the same rules apply but with relaxed trace-length matching tolerance of +/- 1.5 cm. Avoid stubs on PCI bus traces by using daisy-chain routing between PCI devices with no more than 4 inches of trace between any two PCI devices.
