Typical Applications
EPF8452ATC100-3 is suitable for 6 applications: Telecommunications Line-Card Glue Logic, Industrial Control and Factory Automation Backplanes, Legacy Peripheral Bus Bridges (ISA, PC/104, VME), ASIC Replacement in Low-Volume Production, Prototype and Bring-Up for Higher-Density FLEX 10K Designs, Test and Measurement Front-End Logic.
Telecommunications Line-Card Glue Logic
The EPF8452ATC100-3 fits telecom line-card glue-logic designs because its 4,000 usable gates, 452 flip-flops, and 78 user I/Os comfortably absorb bus-bridging, framing, and protocol-conversion state machines that surround legacy TDM backplanes. The 5 V supply matches the rails still common on Class-5 switch and cross-connect boards, while the 100-pin TQFP footprint allows hand-rework on legacy PCBs. Designers typically instantiate this part between an MPC860/860T processor and an E1/T1 framer, where the FPGA handles cell delineation, clock-domain crossing, and interrupt aggregation. Compared with discrete 74-series logic it integrates roughly 60 to 80 SSI packages into one device, lowering BOM cost and trace density.
Recommended
Industrial Control and Factory Automation Backplanes
In industrial backplanes the EPF8452ATC100-3 is used as the master glue-logic device that interfaces PLC CPUs to Fieldbus, Profibus, or CANopen transceivers, because its 5 V I/O is directly compatible with the 5 V transceivers still common on 24 V industrial rails. The 336 logic elements and 78 I/Os are sufficient to implement custom FSMs for stepper-motor sequencing, encoder decoding, and isolated digital I/O expansion on the same chip. The commercial 0 Β°C to 70 Β°C range covers most factory-floor enclosures, and the TQFP-100 package is friendly to wave-solder rework on existing assembly lines. Designers usually pair it with an EPF8282ATC100-3 or EPF6016ATC100-3 when an alternate source is required.
Recommended
Legacy Peripheral Bus Bridges (ISA, PC/104, VME)
The EPF8452ATC100-3 is a natural choice for legacy ISA, PC/104, and VME bus bridges because its 78 user I/Os and 125 MHz internal frequency can sustain 8/16-bit ISA DMA cycles without timing closure issues. The 5 V supply matches the rail that powers the bus transceivers, eliminating level-shifters on the address and data lines. A typical implementation places the FPGA between the host CPU and a peripheral ASIC, generating chip-selects, decoding I/O ports, and arbitrating interrupt requests. Its 452 flip-flops are well-suited to FIFOs and address-latch pipelines, and the in-circuit reconfigurability lets designers iterate firmware logic without re-spinning the PCB.
Recommended
ASIC Replacement in Low-Volume Production
Engineers adopt the EPF8452ATC100-3 to replace gate-array ASICs when production volume does not justify NRE charges, because the FLEX 8000 architecture delivers comparable density and timing predictability at zero NRE. A 4,000-gate design that would normally require a 0.6 Β΅m gate-array NRE of USD 50-150k can be deployed on this part for unit cost under USD 11 at low quantity. The 100-pin TQFP allows standard surface-mount assembly, and the SRAM-based fabric supports field upgrades over JTAG. Customers in medical instrumentation, scientific equipment, and aerospace sub-systems frequently use this approach to consolidate logic and reduce vendor qualification overhead.
Recommended
Prototype and Bring-Up for Higher-Density FLEX 10K Designs
Design teams prototyping FLEX 10K or APEX designs often drop the EPF8452ATC100-3 onto the development board first because it shares the same Altera toolchain (MAX+PLUS II / Quartus), the same configuration scheme, and the same 5 V I/O bank structure. Engineers can validate their state-machine IP, clock distribution, and JTAG chain at the EPF8452ATC100-3 level before migrating to the higher-density part, shortening bring-up by 2-4 weeks. The 336 logic elements and 78 I/Os provide a realistic test bed for peripheral controller logic, with the same Quartus fitter warnings and timing-report formatting engineers will see on the final FLEX 10K target.
Recommended
Test and Measurement Front-End Logic
The EPF8452ATC100-3 is well suited to test-and-measurement front-end designs because its 5 V I/O directly drives the comparators, ADCs, and level-shifters that surround oscilloscope and logic-analyser analog front ends. The 125 MHz internal performance and 452 flip-flops enable deep capture FIFOs and trigger sequencing that older CPLDs cannot sustain. A typical design uses the FPGA to synchronize multi-channel ADC sampling, generate trigger patterns, and pipe data into a host DSP or microcontroller. The TQFP-100 footprint makes it easy to place close to the analog front end, and the in-circuit reconfigurability lets test engineers update trigger logic without opening the chassis.

Key Differentiators
- Highest-density FLEX 8000 device in TQFP-100 footprint (vs EPF8282ATC100-3)
- 5 V native supply without level shifting (vs EPF6016ATC100-3)
- Pin-compatible lead-free upgrade path (vs EPF8452ATC100-3N)
Design Notes
The EPF8452ATC100-3 requires a clean 5 V (Β±5%) supply for both VCCINT (core) and VCCIO (I/O banks). Place a 100 Β΅F bulk electrolytic plus a 0.1 Β΅F ceramic decoupling cap within 1 cm of each VCC pin pair. The part draws roughly 50-150 mA ICCINT during configuration depending on utilization - provision at least 250 mA headroom on the 5 V rail. Add a 10 kΞ© pull-up to nSTATUS and CONF_DONE per the FLEX 8000 configuration reference schematic.
The TQFP-100 (14x14 mm) has 0.5 mm pitch gull-wing leads; use 0.2 mm trace/space rules with a 4-layer PCB for signal integrity. Provide a continuous ground plane under the device and route global clocks (CLK0/CLK1) on the inner layer with controlled impedance (50 Ξ©). Keep the configuration clock (DCLK) trace short (<50 mm) and shielded by ground to avoid double-clocking during configuration.
Estimated: because the part is SRAM-based, it loses configuration on power-down - always pair it with an EPC1/EPC1213/EPC1064/EPC1441 configuration PROM or external controller. Do not leave MSEL[1:0] floating; the mode-select pins must be tied high or low per the desired configuration scheme (PS, AS, or JTAG). When migrating designs from EPF8452ATC100-3 to the EPF6016ATC100-3, verify that I/O voltage tolerance supports 5 V input - older FLEX 6000 I/O banks were not 5 V tolerant and required a series resistor on input pins.
Compliance Information
RoHS, REACH, lead-free, halogen-free and conflict-minerals compliance status were not present in the verified web data for this obsolete part. Marked as [DATA_NEEDED] in the specs array; the lead-free EPF8452ATC100-3N suffix variant may indicate Pb-free finish but should be confirmed against the manufacturer's RoHS CoC before claim.
