EP1K50TC144-2N

The EP1K50TC144-2N is an ACEX-1K family programmable logic device designed for commercial electronic systems that require moderate logic density with embedded memory. Built on the ACEX-1K architecture, it combines a logic array, embedded array blocks (EABs) and flexible I/O to implement system-on-a-programmable-chip (SOPC) functions and specialized megafunctions.

With 2,880 logic elements, approximately 40,960 bits of embedded RAM, and support for MultiVolt I/O and in-circuit reconfigurability, this device targets applications such as communications interfaces, protocol bridging, and custom logic integration where compact, reprogrammable logic and on-chip memory are required.

Key Features

• Logic Capacity  Provides 2,880 logic elements and a maximum system gate count of 199,000, enabling implementation of medium-complexity logic and state machines.
• Embedded Memory  Approximately 40,960 bits of on-chip RAM delivered via embedded array blocks (EABs) for efficient implementation of FIFOs, small buffers, and memory-based megafunctions.
• I/O and Voltage  102 user I/O pins with MultiVolt capability; device operates from a core supply range of 2.375 V to 2.625 V and an internal 2.5-V supply.
• Clocking and Timing  Built-in low-skew clock distribution with options such as ClockLock™ and ClockBoost™ for reduced clock delay and skew; supports multiple global clock and clear signals for complex designs.
• Flexible Interconnect  FastTrack® continuous routing structure, dedicated carry and cascade chains for high-speed arithmetic and high-fan-in logic functions, and tri-state emulation for internal buses.
• Configuration and Test  In-circuit reconfigurability via external configuration devices or JTAG port; includes JTAG boundary-scan test (IEEE Std. 1149.1) without consuming device logic.
• Package and Mounting  Supplied in a 144-pin LQFP package (supplier device package: 144-TQFP 20×20) for surface-mount PCB assembly.
• Commercial Grade Operating Range  Rated for operation from 0 °C to 70 °C and compliant with RoHS environmental requirements.

Typical Applications

• Communications Equipment  Implement protocol conversion, interface logic and timing-critical datapaths using the device's dedicated carry/cascade chains and embedded RAM for buffering.
• System Integration / SOPC  Consolidate glue logic, custom peripherals and memory-mapped functions into a single programmable device to reduce BOM and board area.
• PCI and Bus Interfaces  Supports PCI Local Bus compliance modes described for the ACEX-1K family, enabling use in bus-interface and peripheral adapter designs (see device specifications for supported modes).
• Embedded Memory Functions  Use on-chip EABs for dual-port memory structures, FIFOs or small embedded storage to accelerate data flow and reduce external memory requirements.

Unique Advantages

• Balanced Logic and Memory  Combines 2,880 logic elements with approximately 40,960 bits of embedded RAM to support mixed logic-and-memory designs without immediate reliance on external RAM.
• MultiVolt I/O Flexibility  I/O support for multiple voltage domains enables direct interfacing with 2.5 V, 3.3 V or 5.0 V logic levels as provided by the ACEX-1K architecture.
• Reconfigurability and Test Support  JTAG boundary-scan and in-circuit reconfiguration simplify development, production test and field updates without consuming core logic.
• Deterministic Routing and Arithmetic Support  FastTrack interconnect plus dedicated carry and cascade chains yield predictable timing for adders, counters and high-fan-in logic structures.
• Commercial PCB Compatibility  144-LQFP surface-mount package (20×20 TQFP footprint) for straightforward integration into commercial product PCBs.
