EP1K50TI144-2N Présentation
An FPGA (Field Programmable Gate Array) is a class of programmable logic device (PLD) that combines the architectural flexibility of gate arrays with the design-turnaround benefits of user-programmability. In the system hierarchy, FPGAs sit between discrete logic (small-scale glue logic) and fixed-function Application-Specific Integrated Circuits (ASICs), offering a balance of density, performance, and reconfigurability. ACEX-1K was Altera's second-generation SRAM-based FPGA family and is a hypernym of CPLDs within the broader programmable logic taxonomy.
Key features of the EP1K50TI144-2N include 12 embedded system blocks (ESBs) providing 6 Kbits of dedicated RAM per block, support for multiple I/O standards (LVTTL, LVCMOS, PCI, and others), in-system programmability via IEEE 1149.1 JTAG, and built-in clock management. The device is configured via a serial configuration EPROM (EPC) or the IEEE 1149.1 boundary-scan interface, supporting both SRAM-based and JTAG programming flows.
Typical applications include glue logic replacement, interface bridging, custom state-machine implementation, low-to-medium density data-path processing, and prototyping platforms that can later be ported to higher-density Cyclone or newer Altera/Intel FPGA families. The 144-TQFP package supports traditional surface-mount assembly with a generous 0.5 mm pitch suitable for rework.
When designing with this part, note that ACEX-1K is an older, mature family; verify that current Altera/Intel Quartus software supports the device and confirm long-term availability before committing to new designs. The 144-TQFP package is also convenient for hand-soldered prototypes.

Applications typiques
EP1K50TI144-2N convient pour 6 applications: Glue Logic Replacement and Bus Interface Bridging, Custom State Machine and Protocol Controller, Prototype Platform for ASIC/ASSP Development, Legacy Industrial Control and Test Equipment Sustainment, Low-Density DSP and Data Path Processing, Education and University Logic-Design Labs.
Glue Logic Replacement and Bus Interface Bridging
The EP1K50TI144-2N is well-suited as a drop-in replacement for multiple discrete 74-series logic ICs on legacy boards. With 50K gates and 102 user I/O in a 144-TQFP, a single EP1K50TI144-2N can replace dozens of buffers, latches, transceivers, and custom state machines. The 2.5 V core with multi-standard I/O (LVTTL/LVCMOS/PCI) lets it bridge 3.3 V, 5 V, and mixed-voltage buses without external level shifters. For example, on a 16-bit ISA-to-PCI bridge card, the FPGA implements latches, address decoding, and timing in one chip, reducing BOM cost and board area while adding design flexibility via SRAM reconfiguration.
Recommandé
Custom State Machine and Protocol Controller
Implement custom serial protocols, motor-control state machines, or timing-critical sequencers in the EP1K50TI144-2N. The 360 LABs and -2 speed grade support up to 166.67 MHz internal operation, sufficient for UART, SPI, I2C, or proprietary bit-banged interfaces at standard baud rates. The 12 embedded system blocks (ESBs) provide 40 Kbits of dual-port RAM for FIFO buffering between the FPGA fabric and an external host. Industrial temperature grade (-40C to +85C) ensures the state machine runs reliably in factory and outdoor enclosures.
Recommandé
Prototype Platform for ASIC/ASSP Development
Use the EP1K50TI144-2N as an FPGA prototype before committing to an ASIC tape-out. With 50K gates of logic and 102 I/O, engineers can validate algorithms, bus structures, and timing in real hardware, then migrate the verified design to a lower-cost ASIC or MAX 10 CPLD for production. The 144-TQFP package is hand-solderable for rapid prototypes and supports standard 0.5 mm-pitch PCB fab houses. Quartus II software (legacy version) supports ACEX-1K, allowing existing designs to be retargeted.
Recommandé
Legacy Industrial Control and Test Equipment Sustainment
Many factories still operate machinery whose control boards were built around ACEX-1K FPGAs in the late 1990s and early 2000s. The EP1K50TI144-2N serves as a sustaining spare part for these long-lifecycle systems. Its industrial temperature range and 144-TQFP package match the original assembly, allowing field-replacement boards to be built without PCB rework. Combined with the existing ACEX-1K firmware .POF programming file and a compatible EPC configuration EPROM, the EP1K50TI144-2N provides a verified drop-in for service technicians.
Recommandé
Low-Density DSP and Data Path Processing
For moderate-throughput DSP blocks (FIR filters, FFTs of small windows, custom codecs), the EP1K50TI144-2N provides enough logic and embedded RAM to replace a small DSP chip. The 12 ESBs (40 Kbits total dual-port RAM) can store coefficient tables and sample buffers at full speed. Its 166.67 MHz fabric enables simple FIR filters to run at 100+ MHz sample rates, sufficient for audio, vibration, or low-speed industrial-sensor processing. The flexible I/O accepts 3.3 V ADC/DAC outputs directly.
Recommandé
Education and University Logic-Design Labs
The EP1K50TI144-2N is widely used in university digital-logic and computer-architecture courses as a teaching FPGA. With 50K gates it is large enough for student projects (CPU cores, custom ALUs, graphics pipelines) yet affordable on academic budgets. The 144-TQFP package on a 0.5 mm-pitch breakout board allows hand-soldering for lab kits. Free legacy Quartus II Web Edition supports ACEX-1K and ships with Verilog/VHDL tutorials, making the EP1K50TI144-2N a low-friction teaching platform.

Notes de conception
The EP1K50TI144-2N requires three supplies: VCCINT (2.5 V core) and VCCIO (3.3 V or 2.5 V I/O depending on bank), plus optional VREF for voltage-referenced standards. Decouple each supply pin with a 0.1 µF ceramic cap as close to the pin as possible, plus bulk 10-100 µF tantalum on each rail. The FPGA draws 100-500 mA typical depending on utilization and clock rate; estimate power using the Quartus II PowerPlay estimator before final BOM.
Route all configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) away from switching I/O to avoid coupling. The JTAG chain (TCK, TMS, TDI, TDO, TRST) should be routed as a daisy chain to other devices with proper buffering. Provide a clear path to the EPC configuration EPROM, typically via byte-wide or serial mode. Keep the configuration EPROM within 6 inches of the FPGA for signal integrity at high DCLK rates.
Do not mix 5 V and 3.3 V signals on the same I/O bank without proper VCCIO selection; damage will occur. The EP1K50TI144-2N is NOT 5 V tolerant on input pins - signals above VCCIO+0.5 V will forward-bias the I/O protection diodes. Use external level-shifters (e.g., SN74LVTH245) when interfacing to 5 V buses. Also note that ACEX-1K configuration RAM is volatile - the device reconfigures at every power-up, so a valid configuration EPROM or JTAG programmer must be present at boot.
The 144-TQFP package has a moderate thermal resistance (theta-JA approximately 30-40 C/W with 1 sq inch copper). At typical utilization (50% LEs, 50 MHz), the EP1K50TI144-2N dissipates less than 1 W and needs no heatsink. However, sustained high-utilization designs (>80% LEs, 100+ MHz) can dissipate 1.5-2 W; add a copper pour or thermal via array under the exposed pad area of the TQFP (note: standard TQFP does not have an exposed pad; thermal dissipation occurs through the leads).
