EPF10K20TI144-4N

The EPF10K20TI144-4N is a FLEX 10K family embedded programmable logic device offered in a 144‑lead LQFP surface-mount package. It provides 1,152 logic elements, approximately 12,288 bits of embedded RAM, and up to 102 user I/O pins, making it suitable for custom logic integration in industrial embedded systems and legacy 5 V designs.

Designed for system integration, the device combines a logic array and embedded memory resources to implement glue logic, I/O aggregation, and application-specific functions where board-level consolidation, reprogrammability, and an industrial temperature range are required.

Key Features

• Logic Capacity — 1,152 logic elements and 63,000 gates provide the combinational and sequential resources to implement custom digital functions within a single device.
• On‑chip Memory — Approximately 12,288 bits of embedded RAM to support FIFOs, small buffers, and state storage without external memory.
• I/O Resources — 102 user I/O pins suitable for sensor interfacing, peripheral control, and bus connections in a single package.
• 5 V Supply Compatibility — Specified supply range of 4.5 V to 5.5 V to support legacy 5.0‑V system environments.
• Industrial Temperature Range — Rated for operation from −40 °C to 85 °C for deployment in industrial applications.
• Package & Mounting — 144‑lead LQFP surface-mount package (supplier package listed as 144‑TQFP, 20 × 20) for PCB implementations where a compact quad-flat package is required.
• Family-Level System Features — FLEX 10K family capabilities include in-circuit reconfigurability, JTAG boundary-scan (IEEE 1149.1), built-in low‑skew clock distribution, and architectural support for dedicated carry and cascade chains to implement arithmetic and high‑fan‑in logic functions.
• Programmable Interconnect and Clocking — Family design includes FastTrack continuous routing for predictable interconnect delays and options such as ClockLock and ClockBoost for optimized clock performance.
• Standards & Testability — Implements JTAG boundary-scan test circuitry and family-level support for peripheral interconnect interfaces as documented in the FLEX 10K datasheet.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement custom control logic, I/O aggregation, and timing-oriented functions while operating across the industrial temperature range.
• Legacy 5 V Systems — Replace or consolidate discrete logic in systems that require a 5.0‑V supply domain (4.5 V to 5.5 V support).
• Embedded System Integration — Combine glue logic, small memories, and peripheral interfaces to reduce BOM and simplify board design in embedded products.
• Prototyping and In‑Circuit Reconfiguration — Use the device’s reprogrammability and JTAG support for iterative development and field updates.

Unique Advantages

• Balanced Logic and Memory — The combination of 1,152 logic elements and ~12,288 bits of embedded RAM enables compact implementations of mixed logic and small data‑buffer functions.
• Industrial Reliability — Rated for −40 °C to 85 °C operation and packaged in a standard 144‑lead LQFP for robust board-level deployment.
• 5 V System Fit — Direct support for a 4.5 V to 5.5 V supply simplifies integration into existing 5.0‑V designs without additional level-shifting for the core supply.
• In-System Flexibility — Family-level support for in‑circuit reconfigurability and JTAG boundary-scan enables field updates and streamlined manufacturing test.
• Consolidation of Discrete Logic — High gate count and dedicated architectural features (carry/cascade chains, global clocks) allow replacement of multiple discrete components, reducing PCB area and BOM complexity.
