EP1K50TL144-2 Обзор

The Altera (now Intel) EP1K50TL144-2 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs), delivering up to 50,000 typical gates in a 144-pin TQFP package with industrial-grade temperature rating. Built on a 2.5V core with 0.18 um process technology, the EP1K50TL144-2 provides 360 Logic Array Blocks (LABs), 2,880 logic elements, and 40,960 RAM bits of embedded memory.

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.

Руководство по выбору

Choose EP1K50TL144-2 when maintaining legacy ACEX 1K designs requiring industrial temperature operation in 144-TQFP package with 50K-gate capacity. For commercial temperature (0C to +85C) applications, EP1K50TC144-2 is the cost-down equivalent with identical silicon. If only 30K or 10K gates are needed, the EP1K30TI144-2 or EP1K10TI144-2 (same TQFP-144 footprint) provide cost savings. For NEW designs, consider Cyclone family (EP1C6T144C8 or EP1C12Q240C8) for active production support and lower power, though PCB redesign is required - none are pin-compatible drop-ins.

Заметки по проектированию

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.
