EP1K50TL144-2 Présentation
An FPGA (Field Programmable Gate Array) is a reprogrammable integrated circuit that allows hardware designers to implement custom digital logic through configuration rather than mask-level fabrication. FPGAs belong to the broader category of programmable logic devices (PLDs), sitting alongside CPLDs (Complex PLDs) and SPLDs (Simple PLDs), and serve as the silicon foundation for digital signal processing, glue logic, prototyping, and high-volume parallel hardware. ACEX 1K was Altera's low-cost FPGA line, occupying the space between simple CPLDs and high-density FPGAs like APEX.
Key features of the EP1K50TL144-2 include 102 user I/O pins, embedded array blocks (EABs) for dual-port memory implementation, and 2.5V core operation with MultiVolt I/O supporting 2.5V/3.3V/5.0V interfacing. The device also offers in-system programmability via JTAG, allowing rapid prototyping and field upgrades.
Architecture-wise, the ACEX 1K family combines a continuous interconnect network (routing across rows and columns) with embedded array blocks for memory and specialized logic. The look-up table (LUT) based logic elements deliver efficient synthesis for state machines, datapaths, and bus interfaces, while EABs efficiently implement RAM, ROM, and DSP functions.
Typical applications include DSL modem glue logic, low-cost switches and routers, PCI bridge designs, telecommunications interfaces, and industrial control systems. The 144-pin TQFP package and industrial temperature range also make the EP1K50TL144-2 well suited to legacy telecommunications infrastructure and embedded prototyping.
When designing with this device, note that the ACEX 1K family requires configuration via MAX+PLUS II or Quartus software (legacy support required), and the 144-pin TQFP package has limited I/O headroom for high-pin-count designs. Engineers migrating from ACEX 1K should plan for Cyclone or MAX II successors for new designs.
This page synthesizes distributor pricing, drop-in alternatives from the same ACEX 1K family, and practical design notes not found in the manufacturer datasheet - useful for engineers maintaining legacy systems.

Applications typiques
EP1K50TL144-2 convient pour 6 applications: DSL Modem Glue Logic, Low-Cost Network Switches and Routers, PCI Bridge and Interface Controllers, Industrial Control and Automation, Legacy Telecommunications Infrastructure, Embedded Prototyping and ASIC Replacement.
DSL Modem Glue Logic
The EP1K50TL144-2's 50,000 gates and 40,960 bits of embedded memory make it well-suited for DSL modem glue logic functions including ATM cell processing, TC layer interfacing, and bus arbitration. With 102 user I/Os, the 144-TQFP can connect directly to upstream PHY chips, downstream DSP processors, and memory interfaces without external muxing. The 2.5V core with MultiVolt I/O supports 3.3V PHY/MAC interfacing common in DSL designs, and the embedded EABs efficiently implement dual-port RAM buffers for cell queuing.
Recommandé
Low-Cost Network Switches and Routers
The EP1K50TL144-2's combination of 2,880 logic elements, 360 LABs, and 102 user I/Os makes it appropriate for low-cost switch/router glue logic, MAC address table management, and packet buffer control. Engineers can implement custom lookup tables in the embedded EABs for routing decisions while leveraging the LABs for state-machine based forwarding engines. The 144-TQFP package's exposed thermal pad handles industrial temperature operating environments typical in networking equipment, and JTAG in-system programmability enables field firmware updates.
Recommandé
PCI Bridge and Interface Controllers
The EP1K50TL144-2's 50K gate capacity is sufficient to implement PCI bus bridges, including target and master state machines, parity generation, and address decoding logic. The 102 available user I/Os accommodate 32-bit PCI bus (32 data + 32 address/control + JTAG + misc) plus expansion headers. The MultiVolt I/O (2.5V/3.3V/5V) allows direct interfacing to 5V PCI slots in legacy systems. Embedded memory (40,960 bits) can be used for FIFO buffers between PCI and local bus.
Recommandé
Industrial Control and Automation
The EP1K50TL144-2's industrial temperature rating (-40C to +100C) and robust 144-TQFP package make it suitable for industrial PLCs, motor control interfaces, and sensor signal conditioning circuits. With 2,880 logic elements, engineers can implement PWM generators, quadrature decoders, and industrial protocol stacks (Modbus, Profibus glue). The 40,960 bits of embedded memory support data logging buffers, while the 102 user I/Os accommodate multiple encoder inputs, sensor channels, and isolated communication interfaces.
Recommandé
Legacy Telecommunications Infrastructure
The EP1K50TL144-2 is widely deployed in legacy telecommunications equipment including T1/E1 framer interfaces, HDLC controllers, and ISDN terminal adapters. Its 2.5V core and MultiVolt I/O match the mixed-voltage environments of telecom backplanes, while the 144-TQFP footprint provides enough I/O for serial data streams plus control logic. The device's deterministic timing via Quartus timing analysis is critical for telecom clock-domain crossing, and its in-system JTAG programmability supports field upgrades of deployed equipment.
Recommandé
Embedded Prototyping and ASIC Replacement
The EP1K50TL144-2's 50K gate capacity and JTAG-based in-system programmability make it an ideal prototyping platform for ASIC designs in the mid-complexity range (consumer electronics, automotive subsystems, peripheral controllers). Engineers can iterate RTL designs rapidly without mask costs, validate ASIC functionality in-system, then migrate to low-cost mask ROM for volume production. The embedded EABs can model ASIC SRAM blocks, while the 102 user I/Os emulate typical ASIC pad ring configurations including boundary scan chains.

Notes de conception
The EP1K50TL144-2 requires separate VCCINT (2.5V core) and VCCIO (MultiVolt I/O bank) supplies. According to the Altera ACEX 1K datasheet, VCCIO can be set to 2.5V, 3.3V, or 5.0V to match downstream peripherals. Decoupling: place 0.1 uF ceramic capacitors adjacent to every VCCINT and VCCIO pin, plus 10 uF bulk tantalum per supply rail. Estimated core current: approximately 50-100 mA typical (varies with utilization and clock rate); I/O current depends on bank switching activity.
The 144-pin TQFP package (no exposed thermal pad) has limited thermal dissipation, making the EP1K50TL144-2 suitable only for low to moderate utilization rates. According to Altera's thermal characteristics, theta_JA is approximately 30-40 C/W on a 4-layer PCB with adequate copper pour. For industrial temp (-40C to +100C) operation with high toggle rates, ensure ambient temperature stays below 70C with proper airflow. Estimated: at 25C ambient and 1W dissipation, junction temperature is approximately 55-65C.
For multi-bank I/O designs, route each VCCIO bank separately to allow independent voltage levels. Place JTAG pins (TCK, TMS, TDI, TDO) accessible for in-system programming via header. Use a continuous ground plane beneath the device for return paths and thermal dissipation. Keep clock inputs short and impedance-controlled (50 ohm typical). Configuration mode pins (MSEL0, MSEL1) must be tied high or low per the configuration mode selected (AS, PS, JTAG).
Common pitfalls with the EP1K50TL144-2: (1) Do not assume ACEX 1K support in modern Quartus versions - retain MAX+PLUS II or legacy Quartus II toolchains. (2) Verify all VCCINT and VCCIO pins are powered; missing supply connections cause configuration failure. (3) I/O banks must not be left floating - unused banks should have VCCIO connected to valid voltage. (4) Configuration mode pins (MSEL) must match the intended programming method.
Informations de conformité
Compliance status not available in verified web data; this is an obsolete part from Altera (now Intel). For RoHS-compliant ACEX 1K variants, look for the N suffix (e.g., EP1K50TI144-2N).
