EP1K10TC100-2N - ACEX-1K FPGA, 10K Gates, 576 Cells | Altera
MPN: EP1K10TC100-2N ⚠ Lần mua cuốiEP1K10TC100-2N Tóm tắt
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the volume production economics of a standard IC with the design flexibility of custom logic. ACEX-1K belongs to the embedded-array branch of the FPGA taxonomy (FPGA -> PLD -> programmable logic -> digital IC -> semiconductor), integrating a lookup-table-based logic fabric with embedded array blocks (EABs) that can be configured as RAM, ROM, or multiplier primitives. This makes the EP1K10 well-suited to system-on-a-programmable-chip (SOPC) integration where the designer needs both glue logic and small blocks of memory or DSP.
Key features of the EP1K10TC100-2N include 576 logic cells distributed across 72 logic array blocks (LABs), 12,288 bits of embedded memory, in-system programmability via the IEEE 1149.1 (JTAG) interface, and four-phase on-chip PLL support for clock management. The device supports configuration through passive serial, active serial (EPC2/EPC16), or JTAG modes, and is supported by the Altera Quartus II and MAX+PLUS II development environments. The -2 speed grade provides approximately 0.7 ns gate-delay typical timing at 25 C ambient.
Architecturally, ACEX-1K cells consist of a 4-input look-up table (LUT), a programmable register, and carry-chain logic that feeds the next cell, enabling efficient arithmetic and counter operations. The 100-pin TQFP footprint uses a thin (1.0 mm) body with gull-wing leads on a 0.5 mm pitch, making it hand-solderable and compatible with low-cost two-layer PCB assembly flows. Multi-voltage I/O banks allow 1.8 V, 2.5 V, 3.3 V, and 5 V interfacing without external level shifters.
Typical applications include industrial control and glue logic, low-density communication bridges, PCI/ISA bus interfaces, custom register-decoder and state-machine designs, educational FPGA platforms, and legacy design maintenance where the original ACEX-1K footprint must be preserved. Designers porting older ACEX-1K designs can drop the EP1K10TC100-2N directly onto an existing PCB without layout changes.
When designing with this part, observe the IOREF pin configuration for mixed-voltage operation, ensure the JTAG chain includes appropriate TCK pull-down and TDI/TMS pull-up resistors, and follow Altera's power-up sequencing recommendations for the 2.5 V VCCINT and 3.3 V VCCIO rails. Quartus II 13.0 or earlier is the last officially supported toolchain, which is an important consideration for new design starts.

Ứng dụng tiêu biểu
EP1K10TC100-2N phù hợp cho 6 Áp dụngs: Industrial Glue Logic Replacement, PCI/ISA Bus Bridge and Adapter, Custom State Machine and Protocol Decoder, Educational FPGA Development Board, Legacy Aerospace Avionics Retrofit, Low-Density Communication Bridge.
Industrial Glue Logic Replacement
The EP1K10TC100-2N's 576 logic elements and 72 LABs make it a strong drop-in for legacy glue-logic designs that previously required multiple 74-series TTL or 4000-series CMOS parts. With 66 user I/Os and 2.5 V core / multi-voltage I/O bank support (1.8 V to 5 V), the part can interface directly to 5 V legacy buses without external level shifters. Typical toggling frequency of 200 MHz Fmax comfortably handles register decoding, state machines, and address multiplexing for industrial PLC backplanes. The 100-pin TQFP package keeps board area compact and remains hand-reworkable for prototype revisions, while the commercial 0 C to +70 C temperature range is adequate for indoor control cabinets.

PCI/ISA Bus Bridge and Adapter
With 66 user I/Os, four dedicated clock inputs, and 12 Kbits of dual-port EAB memory, the EP1K10TC100-2N fits PCI-bus target peripherals and ISA-to-local-bus bridges where moderate logic density and small FIFO buffers are needed. The EAB blocks can be configured as 512 x 24-bit FIFOs at full dual-port bandwidth, supporting PCI 33 MHz target cycles with single-cycle latency on a 30 ns budget. Quartus II supports the PCI 33 MHz 32-bit target megafunction for the ACEX-1K family. Multi-voltage I/O bank configuration (5 V VCCIO for PCI, 3.3 V for local logic) eliminates level-shifter ICs. For legacy industrial PC architectures that still rely on ISA, the -2 speed grade provides ample margin on the 8 MHz ISA clock.
Được đề xuất
Custom State Machine and Protocol Decoder
The EP1K10TC100-2N's 576 logic elements and 4-input LUT architecture are well suited to custom state machines, packet decoders, and protocol-conversion engines in telecom and serial-bus interfaces. Typical designs pack 5 to 10 parallel protocol state machines (UART, SPI, I2C master/slave, custom timing-sensitive protocols) into the device with headroom for FIFOs and small register files. The -2 speed grade comfortably handles 100 MHz on-chip operation, supporting oversampling serial decoders at 50 Mbaud. JTAG-based in-system reconfiguration lets developers iterate on state-machine microcode without removing the part from the board, dramatically shortening debug cycles. The 100-pin TQFP package supports dense designs while keeping signal-trace lengths short.

Educational FPGA Development Board
The EP1K10TC100-2N's low typical gate count, hand-solderable 100-pin TQFP package, and free Altera Quartus II Web Edition toolchain make it an accessible teaching platform for introductory digital logic and HDL courses. Students can implement full RISC soft-cores, UART peripherals, and VGA/LCD controllers within 576 LEs, learning resource budgeting and timing closure. The on-chip PLLs and dual-port EABs (12 Kbits) provide exposure to real-world FPGA primitives without needing an expensive high-density part. The commercial 0 C to +70 C range and 2.5 V VCCINT simplify lab power-supply design. Many universities still maintain Altera DE1/DE2 boards based on the older ACEX-1K family for digital-logic labs.

Legacy Aerospace Avionics Retrofit
Aircraft and military systems originally designed around ACEX-1K in the early 2000s still require maintenance spares, and the EP1K10TC100-2N provides a form/fit/function identical replacement for these long-life programs. The 100-pin TQFP footprint, 2.5 V VCCINT, and Altera bitstream format mean existing PCBs and JTAG programming flows work without modification. For harsher thermal environments, the industrial EP1K10TI100-2N variant (-40 C to +100 C) is the recommended substitute, sharing the same TQFP-100 pinout but rated for the wider temperature range. Altera's lifecycle status is Last Time Buy, making inventory preservation critical for legacy sustainment.

Low-Density Communication Bridge
The EP1K10TC100-2N's combination of 576 LEs, 12 Kbits of dual-port EAB, and 66 multi-voltage I/Os makes it a viable bridge between legacy parallel buses (e.g., VME, PC/104, CompactPCI) and modern serial protocols such as SPI, I2C, or even low-speed LVDS. Designs can implement full bridge logic plus small packet FIFOs without external memory. The 100-pin TQFP package and 0.5 mm pitch are still manufacturable on low-cost 2-layer FR-4 PCBs, keeping retrofit costs low. JTAG boundary-scan simplifies in-system test on long-life communication backplanes.

Ghi chú thiết kế
The EP1K10TC100-2N requires two supply rails: VCCINT at 2.5 V (core logic, +/- 5% tolerance per Altera datasheet) and VCCIO at 1.8 V, 2.5 V, 3.3 V, or 5 V depending on the I/O bank configuration. Decoupling per Altera's AN 75 recommendation: place one 0.1 uF X7R ceramic cap and one 10 uF tantalum cap within 5 mm of each VCCINT and VCCIO pin pair. A bulk 100 uF aluminum polymer cap on the main 2.5 V rail helps absorb the inrush current during configuration. Estimated: at 25% toggle density and 50 MHz operation, total power consumption is roughly 200-400 mW.
JTAG chain integrity requires careful PCB routing: keep TCK trace under 100 mm total length, add a 10 kohm pull-up on TMS and TDI, and a 10 kohm pull-down on TCK to keep the chain in a benign state at power-up. Place a 33 ohm series resistor near the TCK driver to dampen ringing. For multi-device JTAG chains, series-terminate TCK near each receiver with 22-33 ohms. Altera Application Note 39 (JTAG) and AN 88 (configuration) provide detailed reference designs.
Common pitfalls with the EP1K10TC100-2N include: (1) failing to hold nCONFIG low until all rails are stable for at least 1 ms after power-up, which can cause configuration failures; (2) using I/O pins assigned to configuration (TDI/TDO/TMS/TCK/DCLK/DATA0) as user I/Os without disabling JTAG and configuration logic; (3) operating VCCIO at 5 V on a bank where the datasheet indicates a max of 3.3 V - check each bank individually. Always refer to the Quartus II Pin Planner output and the ACEX-1K datasheet's bank-IO voltage table before PCB fab.
The 100-pin TQFP package has an estimated theta_JA of approximately 38 C/W on a 2-layer JEDEC test PCB with no airflow. At maximum ambient of 70 C and worst-case power dissipation of about 500 mW, the junction temperature rise is approximately 19 C above ambient, yielding a Tj around 89 C - well below the 125 C silicon limit. For sealed enclosures with no airflow, consider derating to industrial-grade -40 C to +85 C ambient or providing at least 200 LFM of forced cooling. Always validate with the Altera PowerPlay early power estimator.
