EPF8820ATC144-4N

The EPF8820ATC144-4N is a FLEX 8000 family CMOS programmable logic device designed for medium-density, register-rich logic integration. With 8,000 usable gates implemented as 672 logic elements across 84 logic array blocks (LABs) and 112 user I/O pins, this surface-mount FPGA targets applications that require flexible logic, high I/O count, and 5.0 V system operation.

Built for commercial-grade designs, the device supports in-circuit reconfigurability and a range of system-level features from the FLEX 8000 family, making it suitable for bus interface, controller, and coprocessor functions where predictable interconnect and rich register resources are required.

Key Features

• Core architecture and density  8,000 usable gates implemented as 672 logic elements across 84 logic array blocks (LABs) provide register-rich logic suitable for mid-range programmable designs.
• User I/O and package  112 user I/O pins in a 144-pin LQFP surface-mount package (supplier device package listed as 144-TQFP, 20×20) enable broad external connectivity in a compact footprint.
• Voltage and commercial grade  Designed for 4.75 V to 5.25 V supply operation and specified for commercial temperature range (0 °C to 70 °C).
• No embedded RAM  Total on-chip RAM bits: 0 — suitable for designs that use external memory or rely on register resources for state storage.
• In-circuit reconfigurability (ICR)  Supports ICR via external configuration devices or an intelligent controller for field updates and flexible deployment.
• Flexible interconnect and arithmetic support  Family-level features include continuous routing (FastTrack® interconnect), dedicated carry and cascade chains for efficient arithmetic, and tri-state emulation for internal nets.
• I/O capabilities  MultiVolt™ I/O interface at the family level allows the device core to run at 5.0 V while supporting I/O compatibility with 5.0 V and 3.3 V logic levels; programmable output slew-rate control helps manage switching noise.
• Manufacturing and test support  FLEX 8000 family devices include features such as JTAG boundary-scan test (BST) circuitry on selected devices and are fabricated on an SRAM process with low standby power characteristics (typical standby current cited in family documentation).
• Software and design support  Family-level design flow support is available through the documented MAX+PLUS II development system and standard EDA interfaces (EDIF, LPM, Verilog HDL, VHDL) for synthesis and place-and-route.

Typical Applications

• Bus interfaces and protocol bridging  Use the EPF8820ATC144-4N to implement TTL-level bus interfaces, glue logic, and multi-bus aggregation thanks to its high I/O count and flexible routing.
• High-speed controllers  Suitable for control logic in printers, communication peripherals, and embedded controllers where dense register resources and predictable interconnect are valuable.
• Coprocessor and glue logic  Ideal for offloading peripheral processing or implementing custom coprocessor functions using the device’s dedicated carry/cascade chains and abundant flip-flop resources.
• Data transformation and DSP support  Provides register-rich resources for wide-data-path manipulation and fixed-function data transformation tasks that rely on extensive flip-flop and logic element usage.

Unique Advantages

• Rich, register-dense logic: 672 logic elements and 84 LABs provide a balance of combinational and registered resources for stateful designs without external logic proliferation.
• High I/O integration: 112 user I/O pins enable direct interfacing to multiple buses and peripherals, reducing the need for additional I/O expanders.
• 5 V system compatibility: Operates from 4.75 V to 5.25 V and supports family-level MultiVolt I/O compatibility with 3.3 V signals, simplifying mixed-voltage system integration.
• Field reconfiguration: In-circuit reconfigurability lets you update logic in-system via external configuration devices or controllers, supporting iterative development and product updates.
• Standard toolchain support: Documented support for MAX+PLUS II and common HDL/netlist formats streamlines development and integration into existing FPGA tool flows.
• Compact surface-mount packaging: 144-pin LQFP (surface mount) provides a compact board footprint while preserving a high I/O count for space-constrained designs.

Why Choose EPF8820ATC144-4N?

The EPF8820ATC144-4N positions itself as a practical, commercial-grade solution for medium-density programmable logic needs. Its mix of 8,000 gates, 672 logic elements, and 112 I/O pins offers designers a convenient trade-off between logic capacity and board-level integration, particularly for bus-centric and controller applications that benefit from register-rich architectures and in-circuit reconfigurability.

This device is suited to development teams and OEMs that require predictable routing behavior, dedicated arithmetic chains, and standard development-tool support to accelerate design cycles. Its 144-pin surface-mount package and 5.0 V operating window make it straightforward to integrate into existing 5 V systems while supporting mixed-voltage I/O requirements at the family level.
