EPF8820ATI144-1 Visão geral
The FLEX 8000 family is an SRAM-based programmable logic device (PLD) that combines fine-grained logic elements with continuous-channel routing to deliver predictable timing. It is widely used as a flexible substitute for discrete TTL/CMOS glue logic and gate arrays, allowing designers to integrate 5V and 3.3V interfaces through MultiVolt I/O buffers while operating from a 3.0 V to 3.6 V core supply.
Key features include a continuous FastTrack Interconnect routing architecture for deterministic timing, built-in JTAG (IEEE 1149.1) boundary-scan test, in-system programmability through the EPC configuration controller, and four dedicated high-speed clock inputs with on-chip PLL-like global clock distribution. The TQFP-144 package offers an industrial operating temperature range of -40 °C to +85 °C suitable for telecom, industrial control, and embedded computing designs.
Typical applications for the EPF8820ATI144-1 include high-volume glue-logic consolidation in 5V and 3.3V systems, PCI bus interface bridges, legacy ASIC and gate-array emulation, telecom line-card control logic, and industrial automation controllers. Its compatibility with the Quartus II and MAX+PLUS II design environments also makes it a useful bridge in maintenance and long-life-cycle designs.
When designing with the EPF8820ATI144-1, ensure the design tools (Quartus II or MAX+PLUS II) match the device, and verify configuration scheme support. The device is one of the highest-density FLEX 8000 members in a 144-pin TQFP; the same die is also offered in larger packages such as RQ208, R240, and C240 for applications needing more I/O pins.

Aplicações típicas
EPF8820ATI144-1 é adequado para 6 aplicaçãos: Glue-Logic Consolidation in Industrial 5V/3.3V Systems, PCI Bus Interface Bridge, ASIC and Gate-Array Emulation, Telecom Line-Card Control Logic, Embedded Computing Backplanes, Legacy Industrial Control Replacement.
Glue-Logic Consolidation in Industrial 5V/3.3V Systems
The EPF8820ATI144-1 integrates discrete TTL/CMOS glue logic into a single FLEX 8000 FPGA, reducing board area and improving design flexibility. Its MultiVolt I/O buffer supports 5.0 V TTL inputs on a 3.3 V core, removing the need for level shifters when bridging legacy peripherals with modern processors. With 672 logic elements and 112 I/O pins, the device fits typical glue designs in industrial PLC backplanes, factory automation controllers, and motor-drive interface boards. Industrial temperature grade (-40 °C to +85 °C) ensures operation in factory floor environments.
Recomendado
PCI Bus Interface Bridge
The EPF8820ATI144-1 is well-suited as a PCI 5V/3.3V bridge in legacy 32-bit PCI add-in cards and embedded systems. Its 80 MHz global clock and 1.8 ns tpd support the 33 MHz PCI clock domain, while MultiVolt I/O handles 5V PCI signaling with a 3.3V core. 112 user I/O pins are sufficient for multiplexed address/data and side-band signals (REQ#, GNT#, FRAME#, IRDY#, TRDY#). The IEEE 1149.1 JTAG interface eases board-level boundary-scan test of the bridge logic.
Recomendado
ASIC and Gate-Array Emulation
The EPF8820ATI144-1 was widely used in the 1990s as a gate-array emulator for ASIC prototyping. Its SRAM-based programming allows designers to iterate logic changes in minutes rather than the weeks required for masked ASIC spins. The same TQFP-144 footprint is shared with the entire FLEX 8000 family, so engineers can migrate between EPF8282, EPF8452, EPF8636, and EPF8820 without PCB changes, using the highest-density member for final prototypes. This preserves form-factor across the design exploration phase.
Recomendado
Telecom Line-Card Control Logic
In telecom line cards, the EPF8820ATI144-1 provides deterministic, low-latency control logic for T1/E1 framers, LIU interfaces, and protocol glue. The FLEX 8000 family's FastTrack continuous routing architecture delivers predictable timing paths, which is critical for backplane and serial-line control where worst-case delay must be bounded. Industrial temperature operation, 5V-tolerant I/O, and the small TQFP-144 package make it well-matched to compact line-card designs. The device is JTAG-readable for in-system diagnostics.
Recomendado
Embedded Computing Backplanes
The EPF8820ATI144-1 functions as a bus arbiter, address decoder, or interrupt controller on VME, cPCI, and proprietary embedded backplanes. Its 112 I/O pins support multiplexed address/data plus control signals, while the 1.8 ns propagation delay maintains timing margins in 25–33 MHz backplanes. MultiVolt I/O interfaces cleanly with 3.3V processors and 5V peripheral memory. The TQFP-144 industrial-grade package handles the thermal and vibration stresses of industrial embedded enclosures.
Recomendado
Legacy Industrial Control Replacement
Long-life industrial equipment (CNC machines, process controllers, railway signaling) requires replacement of failed EPF8820ATI144-1 parts to keep existing lines running. Independent distributors such as Jotrin and AIChipLink continue to inventory date-coded FLEX 8000 stock for maintenance, repair, and operations. The drop-in TQFP-144 compatibility with higher-density FLEX 8000 family members also allows an upgrade path on the same PCB: a defective EPF8820ATI144-1 can be swapped for an EPF8636ATC144-1 to add spare logic capacity.

Notas de projeto
EPF8820ATI144-1 requires two rails: VCCINT (3.0-3.6 V) for the core logic and VCCIO (3.0-3.6 V) for the I/O banks. Place 0.1 µF ceramic decoupling capacitors adjacent to every VCCINT and VCCIO pin, plus bulk 10-100 µF tantalum or polymer capacitors on each rail. During configuration, inrush current can reach 100-300 mA on VCCINT; use a ramp-up regulator with monotonic output to avoid triggering partial configuration. Connect all GND pins to a low-impedance ground plane.
Distribute VCCINT, VCCIO, and GND pins evenly across the TQFP-144 land pattern. The dedicated CLK pins (CLK0-CLK3) and the four dedicated inputs must be routed as matched-length, controlled-impedance traces if used for high-speed capture (32-bit counters, SDDR). For MultiVolt I/O, group 5V and 3.3V signaling on separate banks and route accordingly. The JTAG chain (TCK, TMS, TDI, TDO) should be pulled to known states through 10 kohm resistors to avoid floating behavior at power-up.
Never connect VCCIO to 5 V even though the inputs are 5V-tolerant — only the inputs tolerate 5V, the output drivers are powered from VCCIO and must remain at 3.0-3.6 V. Also, the device is SRAM-based and loses configuration on power-down, so a non-volatile EPC configuration controller (e.g., EPC1441) is mandatory for production. Finally, MAX+PLUS II or Quartus II software (not Quartus Prime) is required because Quartus Prime has dropped FLEX 8000 support; use legacy toolchains for bitstream generation.
Estimated: at maximum toggle rate on all 112 I/O pins with a 50 pF load, dynamic power consumption can reach 1.5 W (estimated from typical FLEX 8000 values, not a datasheet figure). The TQFP-144 package has a typical theta_JA of around 45-55 C/W without airflow, so junction temperature rise is 70-85 C above ambient. For sustained high-toggle designs, add 200-300 LFM airflow or thermal copper-pour thermal vias below the exposed pad area (when not present, use a continuous ground plane under the package).
