EPF8820ATC144-2 Visão geral
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) built around an array of configurable logic blocks (CLBs) embedded in a programmable interconnect fabric. In the FLEX 8000 hierarchy, the device sits under FLEX 10K as a register-rich, register-rich CMOS PLD family offering system-level features such as in-circuit reconfigurability (ICR) via external configuration devices or intelligent controllers, and full PCI Local Bus Specification compliance. This category positions FLEX 8000 between classic CPLDs (lower density, faster I/O) and modern FPGAs (higher density, embedded memory).
Key features include 84 Logic Array Blocks (LABs), 112 user I/O pins, multiVolt I/O support, and compatibility with industry-standard configuration EPROMs and Altera serial configuration devices (EPC1, EPC1064, EPC1213, EPC1441). The architecture is built on a 0.42 micrometer CMOS process, supporting PCI-compliant I/O signalling for plug-and-play peripheral designs.
Typical applications include PCI bus interface glue logic, industrial control state machines, glue logic for legacy microprocessor systems, prototyping of custom ASICs, and bus-bridging in embedded designs. Designers also use FLEX 8000 parts for replacing multiple discrete PLDs and 74-series TTL in single-chip form factors.
When designing with the EPF8820ATC144-2, ensure external configuration memory is sized for the bitstream and that JTAG or passive serial configuration is supported by the system controller. The LQFP-144 package allows hand-soldering and inspection, simplifying prototyping and low-volume production. Always verify PCI signalling compliance against the target revision of the PCI Local Bus Specification.

Aplicações típicas
EPF8820ATC144-2 é adequado para 6 aplicaçãos: PCI Bus Interface Glue Logic, Legacy Microprocessor Glue Logic, ASIC Prototyping and Design Verification, Industrial Control and State Machine Integration, Bus Bridging and Protocol Conversion, Replacement for Multiple 74-series TTL Devices.
PCI Bus Interface Glue Logic
The EPF8820ATC144-2 fits PCI Local Bus Specification-compliant glue logic because it is officially listed as fully compliant with the PCI SIG PCI Local Bus Specification in the FLEX 8000 family datasheet. With 112 user I/O pins it can bridge a 32-bit PCI bus plus control signals, address decoding, and arbitration state machines. The -2 commercial speed grade suits standard 33 MHz PCI applications where timing closure over the 7.5 ns bus cycle is achievable. Designers typically instantiate the part between a host CPU and a peripheral ASIC to handle bus arbitration, interrupt acknowledge, and configuration space access. Compared with discrete 74-series TTL implementations, the FLEX 8000 integrates tens of SSI/MSI packages into one device, simplifying board layout and improving signal integrity on the PCI bus.
Recomendado
Legacy Microprocessor Glue Logic
The EPF8820ATC144-2 serves as integrated glue logic between legacy microprocessors, memory, and peripheral devices in industrial and embedded systems. With 672 logic cells and 112 user I/O it can replace dozens of discrete 74LS/74F TTL packages implementing address decoding, wait-state generation, bus multiplexing, and interrupt prioritisation. The 5V supply and 0C-70C commercial temperature range match classic x86, 68k, and MIPS host environments. Designers migrating from 7400-series logic benefit from reduced board area, lower power, and faster design iteration through Altera MAX+PLUS II schematic capture. The LQFP-144 package supports hand-rework and inspection during prototyping or low-volume production runs.
Recomendado
ASIC Prototyping and Design Verification
The EPF8820ATC144-2 supports ASIC prototyping by allowing designers to validate custom logic designs before committing to mask production. With 8,000 usable gates the part accommodates mid-complexity ASICs such as peripheral controllers, custom state machines, and protocol converters. In-circuit reconfigurability via JTAG or passive serial allows rapid design iterations - engineers can download revised bitstreams in seconds. The Altera MAX+PLUS II development suite provides VHDL/Verilog synthesis and timing simulation against the same silicon used in production. For volumes below 50,000 units, FLEX 8000 designs often remain in FPGA form to amortise NRE costs across multiple product revisions.
Recomendado
Industrial Control and State Machine Integration
The EPF8820ATC144-2 integrates multi-state control logic, sensor interfacing, and actuator driving in industrial automation systems. With 84 LABs the device can host multiple independent state machines coordinating conveyor logic, motor sequencing, and safety interlocks. The 112 I/O pins handle parallel sensor arrays, opto-isolated inputs, and relay driver outputs while the 0C-70C commercial temperature range fits factory-floor enclosures. Designers often pair the FPGA with isolation buffers and watchdog supervisors to meet IEC 61508 functional safety requirements. The FLEX 8000 architecture's deterministic timing simplifies Worst-Case Execution Time (WCET) analysis for safety-critical state machines.
Recomendado
Bus Bridging and Protocol Conversion
The EPF8820ATC144-2 acts as a bus bridge between legacy and modern peripherals in mixed-vintage embedded systems. With 112 I/O and 672 cells it can implement custom protocols such as ISA-to-PCI bridges, VME-to-PCI adapters, and proprietary backplane converters. The 5V tolerant I/O pins interface directly with classic TTL logic levels while remaining compatible with 3.3V peripherals through multiVolt I/O support. Designers use the FPGA to extend the life of installed equipment without redesigning the entire CPU subsystem. PCI Local Bus compliance ensures interoperability with standard plug-and-play cards in industrial PCs.
Recomendado
Replacement for Multiple 74-series TTL Devices
The EPF8820ATC144-2 replaces dozens of 74LS, 74F, 74HC, and 74ACT TTL packages in dense logic boards by consolidating address decoding, multiplexing, latching, and bus arbitration into a single device. With 8,000 usable gates the FPGA can absorb the equivalent of 30-50 SSI packages, dramatically reducing board area, power consumption, and signal skew between logic blocks. The LQFP-144 footprint remains manageable for hand-soldering prototypes and field repairs. Designers migrating TTL-heavy designs to FLEX 8000 typically report a 5-10x reduction in logic IC count and a corresponding improvement in mean time between failure (MTBF).

Principais diferenciais
- Slower speed grade at lowest price point in the FLEX 8000 ATC144 family (vs EPF8820ATC144-3)
- Hand-solderable LQFP-144 footprint (vs EPF8820ABC225-4U)
- Same die across all EPF8820ATC144 speed grades (vs EPF8452ATC100-4)
Notas de projeto
The FLEX 8000 family requires a stable 5V VCCINT supply with multiple decoupling capacitors. Place 0.1uF ceramic decoupling caps within 5 mm of every VCCINT and VCCIO pin. According to Altera's FLEX 8000 design guidelines, bulk tantalum or polymer capacitors of 22uF-47uF per supply rail are recommended. Power-on ramp should be monotonic; a slow or noisy ramp may trigger configuration errors. The MSL rating was not provided in the verified web data; consult the manufacturer for floor-life information before opening moisture-sensitive bags.
Route all user I/O signals on inner PCB layers with a continuous ground plane beneath the LQFP-144 footprint to control impedance and reduce crosstalk. Match trace lengths within 10 mm for synchronously clocked buses (PCI, ISA) to avoid timing skew. The LQFP-144 has 0.5 mm pitch leads - design solder paste stencils with 0.15-0.20 mm apertures and reflow profiles matching JEDEC J-STD-020. Dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) should be kept short and isolated from switching I/O to prevent noise-induced reconfiguration.
Do not connect VCCIO banks to voltages exceeding 5V - the FLEX 8000 I/O drivers are not 5V-tolerant beyond the rated supply. The -2 speed grade is the slowest commercial variant; if PCI 33 MHz timing closure fails, consider upgrading to -3 or -4 in the same LQFP-144 footprint rather than redesigning the PCB. Verify configuration bitstream size against the selected EPC1/EPC1064/EPC1213/EPC1441 capacity - the EPF8820ATC144-2 requires approximately 1 Mbit of configuration data. JTAG chain ordering should place TDI -> TAP1 -> TDI -> TAP2 -> TDO for multi-device chains.
