An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy between CPLDs (less complex, non-volatile, lower density) and ASICs (highest density, fixed function). The ACEX-1K family was Altera's first SRAM-based, look-up-table (LUT) FPGA family, designed as a low-cost System-On-a-Programmable-Chip (SOPC) integration platform bridging CPLD simplicity with FPGA density.
Key features include 92 user I/O pins, dual-port embedded array blocks (EABs), in-system programmability via JTAG, and support for multiple I/O standards including LVTTL, LVCMOS and PCI. The device operates from a 2.5 V core supply with 3.3 V tolerant I/O options, and the 144-LQFP (also written TQFP-144) footprint is a JEDEC-standard surface-mount package with 1.0 mm pitch.
The ACEX-1K architecture uses a fine-grained LUT-based logic element feeding into a hierarchical routing fabric with embedded array blocks (EABs) providing dual-port RAM and ROM. Per the Altera ACEX 1K Device Family datasheet (2.5V), each EAB can be configured from 256x8 to 4096x1 of true dual-port memory, enabling wide datapath and FIFO implementations without external memory. Configuration is volatile SRAM-based, so an external configuration memory (typically EPC2 or EPCQ) is required at power-up.
Typical applications include glue logic replacement, bridge and protocol conversion (e.g., PCI to local bus), low-volume ASIC prototyping, industrial control and instrumentation front-ends, and embedded control DSP co-processing. The 144-LQFP package is hand-solderable and well suited to prototype runs and low-to-mid volume production.
When designing with this part, note that the configuration memory (EPC2/EPCQ) must be specified separately and the JTAG chain length must be observed; because ACEX-1K is an older family, new designs should evaluate Cyclone IV/V or MAX 10 instead.

典型應用
EP1K10TC144-2 適用於 6 應用s: Legacy Glue Logic and Bridge Replacement, Industrial Control and Instrumentation Front-End, PCI Bridge and Protocol Conversion, Low-Volume ASIC Prototyping, Embedded DSP Co-Processor Interface, Communication Protocol Converter.
Legacy Glue Logic and Bridge Replacement
The EP1K10TC144-2's 576 logic elements and 92 user I/O pins make it well suited as a modern replacement for multiple discrete 74-series glue logic chips or a complex CPLD. Its LUT-based architecture, dual-port EABs (12 Kbit embedded RAM across 3 blocks), and 2.5 V core simplify board-level integration in legacy 5V-tolerant systems via 3.3 V I/O standards such as LVTTL and PCI. The 144-LQFP is hand-solderable, easing field repair work.
推薦
Industrial Control and Instrumentation Front-End
In factory automation front-ends, the EP1K10TC144-2's 92 I/O and dual-port EABs handle parallel sensor interfaces and FIFO buffering for asynchronous data streams. The 2.5 V core with LVTTL I/O simplifies interface to legacy 5V peripherals via series resistors, and the -2 speed grade delivers adequate timing margin for 25 MHz industrial bus protocols. The device's robust SOPC integration reduces BOM cost versus discrete logic implementations.
推薦
PCI Bridge and Protocol Conversion
The EP1K10TC144-2's PCI-compliant I/O standard support and 12 Kbit dual-port embedded RAM make it an effective PCI target or local-bus bridge device. The 3 EABs implement FIFOs for write/read transactions while the 576 LEs handle the protocol state machine. The 144-LQFP package with 92 user I/O is sufficient for 32-bit, 33 MHz PCI target designs, which dominated industrial and embedded computing through the early 2000s.
推薦
Low-Volume ASIC Prototyping
Engineers commonly use the EP1K10TC144-2 as a low-cost (~12-18 USD as of 2026-09-07) ASIC prototype before committing to NRE charges for full-custom silicon. The 10K-gate capacity covers typical peripheral controller functions, and Quartus II provides full Verilog/VHDL synthesis with gate-level simulation. The 144-LQFP is a hand-solderable prototyping package, accelerating iteration cycles. EABs double as dual-port RAM for prototype SOC subsystems.
推薦
Embedded DSP Co-Processor Interface
In DSP co-processing applications, the EP1K10TC144-2 acts as a host bus interface and pre/post-processing engine. Its 3 EABs implement circular buffers and lookup tables for FFT windowing or FIR filter coefficient storage, while 576 LEs handle data routing. The 144-LQFP and 2.5 V core allow co-location with DSPs such as the TMS320C54x series. Per the ACEX-1K datasheet, the -2 speed grade supports 80 MHz internal operation, sufficient for typical pre-processing tasks.
推薦
Communication Protocol Converter
In telecom and networking equipment, the EP1K10TC144-2 implements protocol stack converters between legacy interfaces (UART, SPI, I2C) and modern buses (PCI, parallel local bus). The 12 Kbit embedded RAM buffers packets while 576 LEs handle the state machines. The commercial temperature grade (0C to +70C) and 3.3 V-tolerant I/O simplify integration into indoor central-office and CPE equipment. The 144-LQFP is well suited to medium-density line cards.

主要差異化特點
- Mid-speed -2 grade offers best balance of timing margin and power (對比EP1K10TC144-3N)
- 144-LQFP footprint minimizes PCB rework vs PQFP-208 (對比EP1K10QC208-2N)
- ACEX-1K with JTAG and dual-port EABs vs CPLDs (對比Altera MAX7000 CPLDs (e.g., EPM7128))
設計說明
The EP1K10TC144-2 requires a clean 2.5 V core supply (VCCINT) and a separate 3.3 V (or 2.5 V) VCCIO supply for I/O banks. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 10 uF tantalum or ceramic near the package. The configuration memory (EPC2) must share a stable supply; backplane power sequencing is critical because ACEX-1K is volatile-SRAM based.
Use 4-layer PCB stack-up with continuous ground and power planes. Route JTAG (TCK/TMS/TDI/TDO) with 50 ohm controlled impedance and keep traces under 100 mm to avoid signal-integrity issues. Place the 144-LQFP with 0.4 mm wide traces and 0.2 mm spacing for escape routing. Provide a 10-pin JTAG header for in-system programming and boundary-scan test access.
Three common pitfalls: (1) forgetting the external EPC2/EPCQ configuration memory - ACEX-1K is volatile-SRAM, so without config memory the device powers up unconfigured; (2) mixing nSTATUS and nCONFIG polarity - both are active-low open-drain and require 10 kohm pull-ups; (3) exceeding 2.7 V on VCCINT during hot-plug events - use a sequenced power supply or hot-swap controller. Always verify MSEL0/MSEL1 mode-select resistor values match the chosen configuration mode.
Differential pairs (LVDS) require 100 ohm differential impedance; route the P and N traces within 0.1 mm of each other and keep length matching within 1 mm. For clock inputs, use a guard ground trace on both sides and series-termination at the source. The ACEX-1K family supports up to four global clock networks (CLK0-CLK3) and two PLLs; place the clock source within 50 mm of the dedicated clock pin for jitter control.
