EP1K10TC1443N 概述
A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic by configuring an array of configurable logic blocks (CLBs), embedded memory blocks, and routing resources via SRAM-based configuration cells. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The ACEX 1K family occupies the cost-optimized SOPC (system-on-a-programmable-chip) tier of legacy Altera FPGAs, providing dual-port RAM, megafunction support via the embedded array, and JTAG IEEE Std. 1149.1 boundary-scan test (BST).
Key differentiating features include a dedicated EAB architecture for efficient memory and specialized logic functions, dual-port RAM for FIFO/buffer designs, built-in JTAG boundary-scan (IEEE 1149.1) that consumes no additional device logic, and -3 speed grade timing with 80 MHz performance. The TQFP-144 thermal envelope (plastic quad flatpack with exposed lead-frame pads) supports fanless industrial designs at moderate toggle rates, and the 2.5 V core with PCI-compliant I/Os simplifies 3.3 V/5 V mixed-rail board designs.
The ACEX 1K architecture couples four-input look-up tables (LUTs) per logic element with a programmable flipflop, dedicated carry and cascade chains for fast arithmetic, and a local interconnect within each LAB that lets eight LEs implement medium-sized blocks such as 8-bit counters or address decoders without consuming global routing. Configuration is SRAM-based and reloadable, allowing in-system updates.
Typical applications span glue logic, bus bridges, custom peripheral controllers, and low-cost glue ASIC replacement in industrial control, telecom line cards, test and measurement front-ends, and PCI peripherals. Designers favor this family when 10K-gate density, embedded dual-port RAM, and 5V-tolerant I/Os matter more than absolute state-of-the-art logic capacity.
Design consideration: the 2.5 V core requires careful power sequencing versus 3.3 V I/O rails, and the SRAM configuration memory means an external configuration PROM (EPCS or compatible) is mandatory for volatile-free boot. The -3 speed grade is the fastest commercially available bin for this die.

典型应用
EP1K10TC1443N 适用于 6 应用s: PCI Peripheral Controller, Glue Logic and Bus Bridge, Industrial Control and Instrumentation, Telecom Line Card and Channelized Interface, Test and Measurement Front-End, ASIC Replacement for Mid-Density Designs.
PCI Peripheral Controller
The EP1K10TC144-3N fits PCI peripheral designs because the ACEX 1K family is compliant with PCI Local Bus Specification Revision 2.2 at 5.0 V operation across all 92 user I/Os. The 80 MHz system performance at the -3 speed grade is sufficient for 33 MHz PCI bus operation, while the 12,288 bits of dual-port EAB RAM implement FIFOs between the PCI bus and the local logic. Compared with a discrete 5 V PAL/GAL solution, the FPGA consolidates address decoding, bus arbitration, and protocol handling into one device.
推荐
Glue Logic and Bus Bridge
The EP1K10TC144-3N replaces discrete 74-series glue logic and protocol bridges (e.g., UART-to-PCI, I2C-to-parallel) with 576 logic elements and 92 user I/Os. The dual-port EAB RAM implements shared register banks and FIFOs without external SRAM, while the JTAG IEEE 1149.1 boundary-scan simplifies board-level test. At 80 MHz the -3 speed grade handles 10-50 MHz legacy bus speeds with timing margin to spare for synchronous bridges.
推荐
Industrial Control and Instrumentation
Industrial PLCs and process controllers use the EP1K10TC144-3N for custom I/O expansion, encoder interface, and PWM generation. The 2.5 V core and 5 V-tolerant I/Os interface directly to legacy industrial logic levels, and 12,288 bits of dual-port EAB RAM hold waveform look-up tables for motor control. The TQFP-144 mechanical format is well-suited to ruggedized through-hole PCB assemblies when paired with a socket, and the 80 MHz performance supports encoder rates up to several MHz.
推荐
Telecom Line Card and Channelized Interface
Telecom line cards leverage the EP1K10TC144-3N for T1/E1 framers, HDLC controllers, and channel aggregation logic. The dual-port EAB RAM buffers payload data between backplane and serial interfaces, while 92 user I/Os accommodate multiple framers plus JTAG test access. At 80 MHz the design meets the 1.544/2.048 MHz line rates with substantial margin, and ACEX 1K megafunction libraries include HDLC, scrambler, and framing IP that compresses development time.
推荐
Test and Measurement Front-End
Custom protocol analyzers and logic analyzer front-ends benefit from the EP1K10TC144-3N's 576 logic elements, 92 user I/Os, and JTAG boundary-scan support for in-system test. Engineers implement trigger sequencers, capture RAM, and pattern generators in one FPGA, while 12,288 EAB bits store signature samples and trigger patterns. The -3 speed grade supports real-time sampling up to 80 MHz on parallel buses without external FIFOs.
推荐
ASIC Replacement for Mid-Density Designs
The EP1K10TC144-3N replaces mid-density gate-array ASICs when NRE cost or schedule cannot justify a mask-programmed device. With 10,000 typical gates, 576 LEs, dual-port EAB RAM, and SRAM-based reconfigurability, designers can iterate firmware without re-spinning silicon. The TQFP-144 footprint fits standard 1.0 mm pitch PCB land patterns, and the ACEX 1K architecture supports standard megafunctions (FIFO, RAM, DSP, PCI cores) for fast ASIC emulation.

关键差异点
- Fastest -3 speed grade in the TQFP-144 ACEX 1K family （对比 EP1K10TC144-2N)
- Industrial temperature range with 'N' suffix （对比 EP1K10TC144-3 (no N suffix))
- Same package, same pinout as the broader ACEX 1K family （对比 EP1K100QC208-3N (100K gates))
设计说明
The EP1K10TC144-3N requires two supply rails: VCCINT = 2.5 V for the core and VCCIO = 3.3 V or 5 V for the user I/Os (PCI-compliant at 5 V). Power sequencing should bring up VCCINT before or simultaneously with VCCIO to prevent bus contention; add a 100 uF bulk capacitor and 0.1 uF decoupling per VCCINT/VCCIO pin pair. Estimated: a fully utilized EP1K10 with 80 MHz toggle draws approximately 200-400 mA on VCCINT (per ACEX 1K datasheet power calculator). Decoupling must keep the 2.5 V ripple under 50 mV.
Place the EP1K10TC144-3N with matched-length clocks to within 1 cm, and route configuration and JTAG signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0, TDI, TMS, TCK, TDO) with short, guarded traces. The dual-port EAB RAM benefits from localized routing: keep EAB-related signals within one LAB neighborhood. The TQFP-144 has a 0.5 mm lead pitch; use 0.15 mm/0.20 mm trace/space rules and at least 8 mil via-in-pad or tented vias for thermal relief.
The EP1K10TC144-3N uses SRAM-based configuration, so a configuration PROM (EPC2, EPC4, or compatible serial flash) is mandatory for non-volatile boot. Without it, the FPGA loses configuration on power-down. The 'N' suffix denotes industrial temperature range; omitting it (e.g., EP1K10TC144-3) yields the commercial-temp variant and may fail in industrial environments. Estimated: commercial temp is 0C to +70C while industrial is -40C to +85C for the -3N.
合规信息
ACEX 1K family predates wide RoHS adoption; lead-free/RoHS status for the EP1K10TC144-3N suffix is not documented in the verified web data. Mark as 'unknown' until confirmed from the original Altera/Intel PCN. AEC-Q100 is not applicable for industrial FPGAs.
