EPF8820ATC144-1 Présentation

The Altera (now Intel) EPF8820ATC144-1 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs) housed in a 144-pin Thin Quad Flat Pack (TQFP) package. It provides 672 logic cells across 84 Logic Array Blocks (LABs), 112 user I/O pins, and an equivalent gate count of approximately 8,000 usable gates, operating from a 5V supply. The trailing "-1" speed grade indicates the slowest of the FLEX 8000 speed bins, suitable for cost-sensitive, non-timing-critical applications.

An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, interconnect resources, and configurable I/O cells that engineers can customize after manufacture. FPGAs sit between fixed-function ASICs and CPLDs in the programmable logic hierarchy, offering higher logic density than CPLDs while remaining factory-reprogrammable. The FLEX 8000 family is configured at system power-up from an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1064, EPC1213, or EPC1441), or a system controller, and supports MultiVolt I/O for interfacing with 3.3V or 5.0V logic rails.

Key features include in-circuit reconfigurability (ICR) via external configuration devices, MultiVolt I/O pin operation, a built-in Joint Test Action Group (JTAG) boundary-scan test interface per IEEE Std. 1149.1, and global routing resources for clock and control distribution. The EPF8820ATC144-1 is fabricated on a 5V CMOS process with SRAM configuration memory and is specified for the commercial operating temperature range of 0C to 70C.

Typical applications include glue logic replacement, custom state-machine controllers, bus-interface bridging, and peripheral emulation in industrial control, telecom, and embedded computing systems. The FLEX 8000 architecture is register-rich, with the EPF8820A device providing up to 1,500 flip-flops, making it well-suited to pipelined datapath and small processor glue-logic roles.

When designing with this device, ensure that the configuration scheme is selected and validated before PCB fabrication because FLEX 8000 devices are SRAM-based and lose configuration when power is removed. Plan for a non-volatile configuration memory on the board, and verify that JTAG chain ordering, voltage-level translation, and decoupling are sized for the 5V supply rail. For new designs consider Cyclone IV or Cyclone V as modern, lower-power successors.

Applications typiques

EPF8820ATC144-1 convient pour 7 applications: Glue Logic Replacement, Custom State-Machine Controllers, Bus-Interface Bridging, Peripheral Emulation, Embedded Computing Subsystems, Legacy Telecom Datapath, Test & Measurement Front-End.

🔧

Glue Logic Replacement

The EPF8820ATC144-1's 672 logic cells, 84 LABs, and 112 user I/Os are well-matched to consolidating scattered discrete TTL/CMOS glue logic on legacy boards. With up to 1,500 flip-flops available, the part can replace dozens of 74-series packages while preserving the 5V supply and parallel-EPROM configuration flow familiar to FLEX 8000 designs. Unlike an ASIC, the device is in-circuit reconfigurable (ICR), allowing post-layout bug fixes without board rework.

🏭

Custom State-Machine Controllers

The FLEX 8000 register-rich architecture gives the EPF8820ATC144-1 the flip-flop density required for complex finite state machines used in industrial control, telecom, and instrumentation. Designers can encode wide state vectors, large microsequencers, and bit-serial protocols across the 1,500 available flip-flops. The 144-pin TQFP exposes enough I/O for parallel sensor buses and discrete control lines while keeping the board on a 5V rail.

🌐

Bus-Interface Bridging

Bridging between legacy 5V buses (ISA, PC/104, VME, parallel peripheral) and downstream 3.3V devices is straightforward with the EPF8820ATC144-1 thanks to its MultiVolt I/O feature. Each I/O bank can be set independently for 3.3V or 5.0V operation, allowing level translation and protocol conversion in a single chip. The 112 user I/Os provide generous headroom for parallel address/data/control bridging without external buffers.

🖥️

Peripheral Emulation

The EPF8820ATC144-1 is widely used to emulate obsolete peripheral controllers, custom ASICs, and legacy video or DMA engines in long-lifecycle industrial systems. Its SRAM-based configuration allows the emulation bitstream to be updated as the host system evolves, while the JTAG (IEEE 1149.1) interface simplifies bench bring-up and field diagnostics. Designers can replace a discontinued IC with the same board footprint while preserving original software behavior.

⚡

Embedded Computing Subsystems

In embedded designs, the EPF8820ATC144-1 serves as a coprocessor or peripheral controller alongside a microprocessor or microcontroller. Its 672 logic cells support small RISC cores, DMA engines, and custom interrupt controllers, while 112 I/Os expose the address/data buses needed for tight CPU coupling. The 5V supply and 144-pin TQFP keep it compatible with legacy MCU/DSP baseboards.

🌐

Legacy Telecom Datapath

Datapath and framing functions in legacy telecom line cards and base-station controllers fit naturally into the EPF8820ATC144-1's register-rich architecture. Bit-serial protocols, framing/deframing, HDLC controllers, and small CRC engines map efficiently to the FLEX 8000 LAB structure, and the 112 I/Os handle parallel PCM/TDM buses. Designers can hold 5V system power while gaining a programmable replacement for obsolete ASICs.

🔧

Test & Measurement Front-End

The EPF8820ATC144-1's MultiVolt I/O and 112 user I/Os suit it to custom test and measurement front-ends where mixed-voltage analog-to-digital converters and parallel display buses must be sequenced and timed. The 1,500-flip-flop headroom supports custom trigger logic, counters, and timing generators that would otherwise require multiple discrete PLDs. JTAG access speeds bench bring-up and in-field firmware updates.

What is the EPF8820ATC144-1?
The EPF8820ATC144-1 is a member of Altera's FLEX 8000 family of CMOS SRAM-based FPGAs. It contains 672 logic cells organized into 84 Logic Array Blocks, provides 112 user I/Os, and is housed in a 144-pin TQFP package. It operates from a 5V supply and supports MultiVolt I/O for 3.3V or 5.0V signaling. The trailing "-1" denotes the slowest speed grade.
How many logic cells and LABs does the EPF8820ATC144-1 have?
The EPF8820ATC144-1 contains 672 logic cells distributed across 84 Logic Array Blocks (LABs). It also provides up to 1,500 flip-flops and approximately 8,000 usable gates, making it a register-rich device for its era. These resources support pipelined datapaths and small glue-logic subsystems.
What is the difference between EPF8820ATC144-1, -2, -3, and -4?
The trailing suffix indicates the speed grade: -1 is the slowest, -4 is the fastest. Pinout and logic resources are identical across speed grades; only timing closure differs. Choose -1 for cost-sensitive, non-timing-critical applications and -4 where higher Fmax is required.
What configuration memory does the EPF8820ATC144-1 use?
The EPF8820ATC144-1 is SRAM-based and loses its configuration when power is removed. It must be loaded at power-up from an Altera serial configuration device such as EPC1, EPC1064, EPC1213, or EPC1441, or from an industry-standard parallel EPROM driven by a system controller. The MultiVolt I/O interface supports 3.3V or 5.0V configuration peripherals.
Where can I buy the EPF8820ATC144-1?
The EPF8820ATC144-1 is an obsolete Altera/Intel part and is not actively stocked at major franchised distributors. Used and refurbished inventory can occasionally be sourced through specialist brokers, legacy-component distributors, and auction platforms. Confirm authenticity, lot date code, and lead-free status before purchase.
What is the price of the EPF8820ATC144-1 in 2026?
Because the EPF8820ATC144-1 is obsolete, list pricing is not maintained by franchised distributors. As of 2026-09-12, secondary-market prices range widely based on lot size, condition, and traceability. The XAIPART quote tiers above (1 / 10 / 100 / 500 / 1000 pcs) reflect indicative broker pricing as of that date and are subject to availability.
What is the lead time for the EPF8820ATC144-1?
Lead time for the obsolete EPF8820ATC144-1 is variable because it depends on broker stock. Franchised-distributor lead times are not applicable. Plan for 4-12 weeks when sourcing through authorized brokers and validate the date code and traceability paperwork with the supplier before placing a production order.
Is the EPF8820ATC144-1 still in production?
No. The EPF8820ATC144-1 belongs to the FLEX 8000 family, which was discontinued by Altera (now Intel) and is classified as obsolete. For new designs, Intel recommends migrating to the Cyclone IV or Cyclone V families, which provide higher logic density, lower power, and active lifecycle support.
What is the difference between EPF8820ATC144-1 and EPF8820ATC144-4?
Both parts share the same 144-pin TQFP package, 672 logic cells, 84 LABs, 112 user I/Os, and 5V supply. They differ only in speed grade: -1 is the slowest and -4 is the fastest. Logic, pinout, and footprint are identical, so they are drop-in compatible when timing margins allow.
Can the EPF8820ATC144-1 be replaced by a Cyclone device?
Direct drop-in replacement on the same 144-pin TQFP footprint is not possible because Cyclone IV and Cyclone V devices use different packages, I/O standards, configuration schemes, and Quartus device libraries. A PCB redesign is required, but the migration typically reduces power, increases performance, and improves tool support.
Where can I download the EPF8820ATC144-1 datasheet PDF?
The Altera/Intel datasheet for the FLEX 8000 family, which covers the EPF8820ATC144-1, is available through legacy Altera documentation mirrors such as alterasemi.com and alldatasheet.com. Search the family datasheet (FLEX 8000 Device Family datasheet) rather than a per-pin PDF because FLEX 8000 documentation is consolidated at the family level.
What package does the EPF8820ATC144-1 use?
The EPF8820ATC144-1 uses a 144-pin Thin Quad Flat Pack (TQFP) package, 22 mm x 22 mm body with 0.5 mm pitch and gull-wing leads. Pin 1 is located by the standard TQFP indicator (dot or beveled edge) and the pinout is documented in the FLEX 8000 family datasheet.
What is the pinout of the EPF8820ATC144-1?
The full 144-pin TQFP pinout is documented in the FLEX 8000 family datasheet. The package exposes dedicated JTAG pins (TCK, TMS, TDI, TDO), configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL[0..2], DCLK, DATA[0..7] in parallel mode), global clock pins, and 112 user I/O pins assigned to I/O banks A through D.
Is the EPF8820ATC144-1 RoHS compliant?
RoHS compliance for the EPF8820ATC144-1 cannot be confirmed from current Altera/Intel documentation because the part is obsolete. Many legacy FLEX 8000 devices were originally Pb-bearing and later re-released as lead-free variants; confirm the specific finish (Sn/Pb vs lead-free) with the date code and manufacturer paperwork before use in a RoHS-restricted build.

Guide de sélection

Choose the EPF8820ATC144-1 when you need a cost-optimized, 5V-tolerant FPGA with 672 logic cells in a 144-pin TQFP and timing margins are generous enough to accept the slowest FLEX 8000 speed grade. It is well-suited to glue-logic replacement, custom state-machine controllers, bus-bridging, and legacy peripheral emulation in industrial and telecom systems where 5V rails are still in use. For timing-critical paths, upgrade to the -2, -3, or -4 speed grade of the same die - all share the identical 144-pin TQFP footprint. For RoHS-restricted builds, migrate to the "N" suffix variant (EPF8820ATC144-2N, -3N, or -4N) which adds a lead-free finish. For new designs, prefer an active Cyclone IV or Cyclone V device - the FLEX 8000 family is obsolete and supported only through broker channels.

Principaux différenciateurs

  • Identical footprint, different speed grade (vs EPF8820ATC144-4)
  • 5V MultiVolt I/O architecture (vs EPF8820ATC144-3N (also Altera FLEX 8000))
  • Lead-free variant available in same footprint (vs EPF8820ATC144-4N)

Notes de conception

The EPF8820ATC144-1 requires a stable 5.0V VCCINT (core) supply and per-bank VCCIO supplies that can be set independently for 3.3V or 5.0V operation. Place 0.1uF decoupling capacitors as close as possible to every VCCINT and VCCIO pin, and add bulk 10uF-47uF tantalum or ceramic capacitors near each supply pin. Power-up sequencing must satisfy the FLEX 8000 requirements: VCCINT and VCCIO must ramp monotonically to ensure proper configuration.

FLEX 8000 devices are SRAM-based and lose their configuration when power is removed. A non-volatile configuration source (EPC1, EPC1064, EPC1213, EPC1441, or parallel EPROM) is required for production boards. The nCONFIG, nSTATUS, and CONF_DONE pins must be pulled and monitored per the datasheet; failing to do so results in configuration failure at power-up. During JTAG programming, ensure the JTAG chain order matches the BSDL file before asserting nCONFIG.

Route configuration and JTAG signals (TCK, TMS, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE, MSEL, DCLK, DATA[0..7]) away from fast-switching user I/O to avoid coupling into the configuration logic. Keep global clock pins short and guarded by ground on both sides. Because the 144-pin TQFP has 0.5 mm pitch, use 0.15 mm/0.20 mm trace-and-space rules and verify the PCB vendor supports fine-line manufacturing.

MultiVolt I/O allows each bank to operate at 3.3V or 5.0V but level translation is only between VCCIO and the FPGA core - never between banks with different VCCIO unless a level-shifting buffer is added. When mixing 3.3V and 5.0V peripherals, place 5V-tolerant buffers on 3.3V outputs that drive 5V inputs to prevent leakage. Use IBIS simulation to validate edge rates on parallel buses that exceed 50 MHz.
