Detailed Description

Member of the Altera FLEX 10K FPGA family. Mid-density, legacy 5V programmable logic device designed for custom digital logic, state machines, and embedded memory use in mature platforms. Speed grade -3 for faster timing. Package code LC84 indicates 84-lead J‑leaded PLCC. Ideal for sustaining and repairing existing systems built around FLEX 10K. Current listing shows Quantity 2122 and Date Code 18+, suitable for production maintenance and field service needs.

Key Features

5V, SRAM-based FPGA architecture (FLEX 10K family)

Programmable logic array with embedded memory blocks (EAB) for small on-chip RAM

Fast speed grade (-3) for tighter timing margins

JTAG boundary-scan support for test and in-system programming (family feature)

Broad I/O standards support typical of legacy TTL/CMOS systems

LC84 package optimized for socketed or board-level legacy upgrades

Mature toolchain support in classic Altera/Intel software

Key Advantages

Drop-in solution for legacy FLEX 10K designs

Stable, well-known behavior in long-life industrial and communications platforms

Quick turnaround for repairs and sustaining projects

Reduces redesign cost compared to migrating an entire system

Broad ecosystem and documentation available for legacy FPGAs

Packaging

Type: LC84 (84-lead J‑leaded PLCC)

Material: Molded plastic encapsulation

Size: Standard PLCC-84 footprint (compact square body with J‑leads around the perimeter)

Pin configuration: 84 J‑leads; perimeter lead layout for easy socket or through-hole compatible footprints where applicable

Thermal characteristics: Plastic package; thermal performance depends on board design, airflow, and power use; consult the datasheet for θJA/θJC guidance

Electrical properties: 5V family device; I/O compatible with common TTL/CMOS levels used in legacy systems; exact limits and timing specs are in the datasheet

Package/Case reference in listing: 1247 (supplier/package reference code)

Marking: LC84 indicates the package; -3 is speed grade; N suffix denotes lead-free/RoHS in many listings

Lifecycle

Status: Legacy/NRND to obsolete in many regions. Procurement is focused on sustaining and replacement needs.

Direct equivalents: Same device in other packages or speed grades may exist (for example, EPF10K10 variants with different package suffixes or grades). Availability varies; pin compatibility depends on package.

Recommended migration paths: For new designs, consider Intel Cyclone family FPGAs or Intel MAX series (if lower density and non-volatile requirements fit). Note: Voltage and I/O level differences exist; not pin-compatible.

Action: For a detailed, up-to-date list of equivalent or alternative models tailored to your board and timing needs, please contact our sales team via the Y-IC website. We will match package, speed, voltage, and tool support for a smooth transition.

Key Application Areas

Industrial control and automation (legacy PLC and motion systems)
