EP1K10QC208-3N Visão geral
An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor whose logic fabric, consisting of configurable logic blocks (LBs/LABs) interconnected by a programmable routing matrix, lets designers implement arbitrary digital circuits. FPGAs sit between fixed-function Application-Specific Integrated Circuits (ASICs) and software-programmable microcontrollers in the design hierarchy: ASIC -> FPGA -> CPLD -> Microcontroller -> Microprocessor. The ACEX-1K family specifically pioneered embedded array blocks (EABs) that combine look-up-table logic with dedicated dual-port RAM, accelerating data-path and DSP designs for the early 2000s.
Key features include embedded dual-port SRAM via EABs, multi-volt I/O supporting 2.5 V and 3.3 V interfaces, in-system programmability through the IEEE 1149.1 JTAG port, and on-chip phase-locked loops for clock management. The 208-BQFP variant is a metric quad flat pack with a generous perimeter-I/O arrangement, well suited for legacy industrial backplanes where through-hole or surface-mount gull-wing leads are preferred over fine-pitch BGAs.
Typical applications span industrial control, telecommunications glue logic, glue/bridge functions in telecom line cards, prototyping for ASIC designs, and legacy military/aerospace retrofits. The 120 user I/Os and 12 Kbits of block RAM enable moderate-complexity state machines and small FIFO buffers.
When designing with this device, remember that ACEX-1K predates modern configuration schemes - it requires an EPC configuration EPROM or microcontroller-driven passive serial configuration. Designers migrating to contemporary Cyclone or MAX families should evaluate Cyclone II/III/IV as functional successors, accepting full PCB redesign because no pin-compatible modern equivalent exists.

Aplicações típicas
EP1K10QC208-3N é adequado para 6 aplicaçãos: Industrial Control Glue Logic, Telecommunications Line-Card Bridge Logic, ASIC Prototyping Platform, Legacy Military/Aerospace Sustainment, Test & Measurement Front-End, Data-Acquisition Backplane Interface.
Industrial Control Glue Logic
The EP1K10QC208-3N fits industrial control glue-logic applications because its 10K-gate capacity and 120 user I/Os handle sensor multiplexing, encoder interfacing, and fieldbus glue between PLCs. The 208-BQFP package has a generous 0.5 mm lead pitch that supports hand-soldering and rework on legacy backplanes where fine-pitch BGA rework is impractical. With a 200 MHz internal frequency at the -3 speed grade and 2.5 V core on 0.22 µm CMOS, the device delivers deterministic timing for hard-real-time control loops while consuming modest power. The 72 LABs and 12 Kbits of embedded RAM (EABs) are sufficient for protocol state machines, encoder counters, and small data buffers without external SRAM.
Recomendado
Telecommunications Line-Card Bridge Logic
In telecom line-card bridge applications, the EP1K10QC208-3N provides protocol conversion, framing, and clock-domain crossing between TDM backplanes and packet processors. Its 120 user I/Os comfortably handle parallel TDM buses (e.g., H.110/H.100), and the on-chip dual-port EAB RAM implements small FIFOs without external memory. The 2.5 V core combined with multi-voltage I/O (3.3 V tolerant) interoperates seamlessly with older telecom ASICs while remaining compatible with newer 2.5 V logic. The 200 MHz fabric supports STS-1/STM-0 byte clock rates with comfortable timing margin.
Recomendado
ASIC Prototyping Platform
The EP1K10QC208-3N is a long-standing choice for ASIC prototyping in academic and small-volume commercial designs because it can emulate a target ASIC's logic and I/O before tape-out. The 208-BQFP package is breadboard- and daughterboard-friendly: its 0.5 mm pitch supports 0.1-inch prototyping adapters. With 576 logic elements and 72 LABs, the device can hold a representative slice of an ASIC for verification, and the JTAG (IEEE 1149.1) port allows in-system reconfiguration to iterate design revisions rapidly. Quartus II MAX+PLUS II development flow is well documented for this device family.
Recomendado
Legacy Military/Aerospace Sustainment
The EP1K10QC208-3N remains in service on military and aerospace platforms where the original ACEX-1K design must be sustained over multi-decade field life. The 208-BQFP's robust gull-wing leads survive thermal cycling, vibration, and conformal coating processes better than BGA parts, making the device well suited for avionics and shipboard retrofit programs. The part's mature silicon (0.22 µm CMOS) has well-characterized radiation and reliability data accumulated over twenty years of field deployment, which is critical when obsolescence management is preferred over redesign.
Recomendado
Test & Measurement Front-End
In test and measurement instruments, the EP1K10QC208-3N implements timing generators, pattern sequencers, and front-end DSP glue between analog converters and downstream processors. The 120 user I/Os support parallel LVDS-style interfaces to ADC/DAC front-ends, while the 12 Kbits of embedded RAM buffer capture data at the instrument's sample rate. The 200 MHz internal fabric allows real-time DSP pre-processing (CIC filters, gain control) without external logic.
Recomendado
Data-Acquisition Backplane Interface
The EP1K10QC208-3N is well suited for data-acquisition backplanes that aggregate multiple ADC channels into a single FPGA for buffering and protocol framing. With 120 user I/Os the FPGA can serve up to 15 parallel 8-bit ADC channels or fewer high-resolution serial LVDS channels. The dual-port EABs function as ping-pong buffers between the ADC sample domain and the backplane transmission domain. The 208-BQFP package's perimeter I/O is convenient for backplane applications where signal routing enters and exits from the four sides of the IC.

Principais diferenciais

- Pb-free RoHS-compliant finish (vs EP1K10QC208-3)
Notas de projeto
The EP1K10QC208-3N requires a stable 2.5 V core supply on VCCINT pins (typically 6-8 pins distributed around the package) and one or more I/O bank supplies on VCCIO pins for the multi-voltage I/O (2.5 V or 3.3 V). Decoupling per ACEX-1K reference design calls for one 0.1 µF ceramic plus one 10 µF tantalum per VCCINT pin pair and one 0.1 µF per VCCIO bank. Power sequencing is not required - VCCINT and VCCIO can ramp simultaneously within 100 ms of each other. Estimated: total quiescent current at 100 MHz, 25 °C, all I/O static, is approximately 30 mA; dynamic current scales with toggle rate.
The 208-BQFP package uses 0.5 mm lead pitch with gull-wing leads - route signals on a 0.1 inch / 2.54 mm grid where possible for hand-routing or simple 2-layer board compatibility. Place at least one 0.1 µF decoupling capacitor within 5 mm of every VCCINT pin and every VCCIO pin. Provide a solid ground plane on the layer immediately beneath the device; do not route signals under the BQFP body. Total land pattern is approximately 30 mm × 30 mm - reserve adequate board area and clearance for rework.
Three pitfalls to avoid: (1) Do not confuse the EP1K10QC208-3N (Pb-free) with the EP1K10QC208-3 (SnPb) - the latter cannot be assembled into a RoHS-compliant product. (2) Do not attempt to substitute the EP1K10TC100-3N (100-pin TQFP) - despite the same gate count, the 100-pin TQFP has different I/O mapping and is NOT pin-compatible with the 208-BQFP. (3) Do not assume EPC configuration EPROM compatibility with newer MAX/Cyclone configuration schemes - ACEX-1K uses legacy passive-serial configuration which requires EPC2/EPC16 or a microcontroller.
JTAG (IEEE 1149.1) boundary-scan is fully supported - route TMS, TCK, TDI, TDO to a standard 0.1 inch JTAG header for programming and board-test access. Configuration mode selection (passive serial vs JTAG) is set via the MSEL pins; tie MSEL[1:0] to the appropriate logic level for your chosen configuration source. CLKUSR pin routes the user oscillator into the device for clock management - keep this trace short and isolated from noisy I/O. Use Quartus II version 13.0 SP1 or MAX+PLUS II for design entry (both legacy flows).
