EP1K10TC100-1 - ACEX 1K FPGA, 10K Gates, 100-TQFP | Altera
MPN: EP1K10TC100-1 ✗ Cuối đờiEP1K10TC100-1 Tóm tắt
An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that allow the hardware function to be defined after manufacture. ACEX 1K belongs to the low-cost, 2.5V SRAM-lookup-table (LUT) based FPGA family from Altera and is one generation below the APEX and Cyclone product lines. Within the broader programmable logic taxonomy, ACEX 1K sits between classic CPLDs (smaller, non-volatile, lower density) and modern high-density FPGAs such as Cyclone and Stratix.
Key features of the EP1K10TC100-1 include 12,288 bits of embedded dual-port SRAM, 72 logic array blocks (LABs), 66 user I/Os, JTAG-compliant boundary-scan test support (IEEE Std 1149.1), and embedded array blocks (EABs) that can be configured as memory or specialized logic functions such as multipliers and DSP primitives. The TQFP-100 footprint is a JEDEC-standard surface-mount package suitable for conventional reflow assembly.
Typical applications include glue logic replacement, custom interface bridging (UART, SPI, I²C, parallel bus), low-density DSP, industrial control, telecommunications line cards, prototyping of ASIC functions, and educational platforms. Because ACEX 1K devices are SRAM-based, they must be configured at every power-up from an external configuration memory (EPCS or compatible), which is a key system-level design consideration.
When designing with this FPGA, ensure that a 2.5V regulator with adequate decoupling is placed close to the VCCINT pins, that JTAG chain integrity is verified, and that I/O bank voltage compatibility (VCCIO) is matched to the connected peripherals.

Ứng dụng tiêu biểu
EP1K10TC100-1 phù hợp cho 6 Áp dụngs: Glue Logic Replacement on Legacy Boards, Custom UART/SPI/I²C Interface Bridge, Low-Density DSP / FIR Filter Coprocessor, Industrial Control / PLC Logic Consolidation, ASIC Prototyping / Educational FPGA Platform, Telecom Line-Card Glue and Framing Logic.
Glue Logic Replacement on Legacy Boards
The EP1K10TC100-1's 576 logic elements, 100-pin TQFP footprint and 2.5V core make it ideal as a drop-in replacement for multiple discrete 74HC/74F-series glue-logic packages on legacy interface cards. With 66 user I/Os and 250 MHz internal performance, the part absorbs address-decoding, latch and bus-multiplexer functions that previously consumed 6-10 small-logic ICs, reducing board area and BOM cost. Its SRAM-based fabric allows last-minute logic changes via JTAG re-configuration, eliminating respins of masked logic. For sustaining projects on older industrial PC/104, VME and CompactPCI boards, this part consolidates discrete logic into a single re-programmable device while keeping the 100-TQFP layout intact.

Custom UART/SPI/I²C Interface Bridge
With 12,288 bits of dual-port SRAM and 72 LABs, the EP1K10TC100-1 provides enough headroom to implement a custom bus-bridging function (UART to SPI, I²C to parallel, etc.) on legacy telecom and industrial-control line cards. The 250 MHz fMAX comfortably supports multi-megabaud serial rates while leaving logic capacity for state machines and FIFO buffering. The 100-TQFP package leaves all 66 user I/Os available for external bus pins, and ACEX 1K Embedded Array Blocks (EABs) can absorb the small dual-port FIFOs without external SRAM. This makes the EP1K10TC100-1 a strong fit for low-volume instrumentation bridges where a custom ASIC would be uneconomical.

Low-Density DSP / FIR Filter Coprocessor
The EP1K10TC100-1's 12-kbit dual-port embedded memory is well matched to small DSP primitives such as FIR filters, multipliers and correlators used in audio baseband processing. Altera's legacy MegaWizard Plug-In library provides multiplier and DSP megafunctions that map directly onto EABs, allowing 8-tap × 8-bit FIR filters to fit inside a single device. Running at 250 MHz, the part can sustain >100 MSPS processing of narrow-band signals - sufficient for ultrasound front-ends, audio EQ, or vibration analysis. The TQFP-100 footprint is easy to reflow on FR-4 evaluation boards, making this part a popular choice for educational DSP labs and proof-of-concept designs.
Được đề xuất
Industrial Control / PLC Logic Consolidation
Industrial PLCs and motor-control boards often need to consolidate multiple 24V-tolerant I/O channels with deterministic logic. The EP1K10TC100-1 in 100-TQFP provides 66 user I/Os with programmable 2.5V/3.3V I/O standards and 250 MHz internal performance - enough capacity to absorb ladder-logic equivalent state machines, encoder counters and PWM generators. Its SRAM configuration allows field firmware updates via JTAG, simplifying factory-floor reprogramming. For existing production lines that already use ACEX 1K and need to sustain spares, the EP1K10TC100-1 (and its lead-free -1N variant) is the proven choice for PLC digital sub-assemblies.
Được đề xuất
ASIC Prototyping / Educational FPGA Platform
The EP1K10TC100-1 is widely used in university digital-design courses and ASIC prototyping kits because its 576 logic elements and 100-TQFP footprint are large enough to host small RISC cores (e.g., PicoBlaze) yet small enough to allow quick compile times under Altera Quartus II Web Edition. Free development tools (Quartus II 9.0sp2 / 13.0sp1 legacy) and Verilog/VHDL support allow students to prototype combinational/sequential logic, finite state machines and small CPUs at sub-$20 BoM cost. Its JTAG boundary-scan and on-chip debug (SignalTap) make the EP1K10TC100-1 a classic teaching vehicle for digital-design and computer-architecture labs.
Được đề xuất
Telecom Line-Card Glue and Framing Logic
Legacy telecom line cards use the EP1K10TC100-1 to perform HDLC framing, E1/T1 line coding and small FIFOs between framer ICs and backplane ASICs. The 12-kbit dual-port SRAM absorbs per-channel elastic stores, while the 72 LABs handle framing and alarm-detection state machines. With 250 MHz fMAX the FPGA can comfortably pace multiple E1/T1 streams and run simple BERT pattern generators. The 100-TQFP package provides enough I/Os (66 user I/Os) for several parallel framer interfaces, making this part a long-standing choice for legacy SDH/PDH equipment sustaining production.

Ghi chú thiết kế
The EP1K10TC100-1 needs a clean 2.5V ±5% rail on each VCCINT pin (with 0.1 µF + 10 µF decoupling close to every VCC pin) and a separate VCCIO rail sized to the I/O-bank standard used (typically 2.5V or 3.3V). Because the device is SRAM-based it draws a configuration surge at every power-up; design the regulator with 250 mA peak capability and use a power-good signal to hold nCONFIG low until the rails are stable. ACEX 1K core current rises with logic utilisation - at 70-80% utilisation expect 60-120 mA on VCCINT - so do not undersize the regulator.
Route the four global clock inputs (CLK0-CLK3) as short, matched-length traces with series-termination at the source to avoid reflections. Keep JTAG signals (TDI, TDO, TMS, TCK) away from switching I/O edges and place a 10 kΩ pull-up on nCONFIG. The 100-TQFP 0.5 mm-pitch land pattern requires fine-pitch PCB capability; use 4-mil trace/space and a 4-layer stack-up with a continuous ground plane to maintain signal integrity on the 66 user I/Os.
ACEX 1K devices are SRAM-based and lose configuration when VCCINT drops below 2.4V; design brown-out protection so the part does not enter an indeterminate state at intermediate voltages. Verify CONF_DONE rises within the spec time after nCONFIG goes high, otherwise the part will not accept a configuration stream. The -1N lead-free variant is RoHS-compliant but is functionally identical to -1 — never assume -1 is RoHS or that -1N is non-RoHS, since the suffix denotes the finish, not the silicon.
Thông tin tuân thủ
EP1K10TC100-1 (without the N suffix) uses the legacy matte-tin/lead finish and is non-RoHS; the -1N variant is RoHS / Pb-free. ACEX 1K devices are not AEC-Q100 qualified and are not intended for automotive safety-critical applications. Use the Cyclone series for new automotive-grade programmable logic requirements.
