EP1K50XXC Descripción general
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable logic hierarchy between fixed-function ASICs and software-driven microcontrollers: microcontrollers execute firmware, while FPGAs realize parallel hardware pipelines. The ACEX 1K family specifically targets glue logic, bus interfacing, and moderate-complexity state machine replacement where a small CPLD is too small but a full ASIC is uneconomical.
Key features of the EP1K50XXC include 2,880 logic elements, 40 embedded array blocks (EABs) providing 40 Kbits of dual-port RAM, a maximum of 333 user I/O pins, and 5 V tolerant I/O with multi-voltage support. The device operates from a 2.5 V core supply, is in-system programmable via the IEEE 1149.1 JTAG interface, and supports configuration via passive serial, active serial, and JTAG modes for flexible factory or field programming.
The ACEX 1K architecture combines an efficient logic-element fabric with distributed embedded memory, allowing designers to implement FIFOs, look-up tables, and small register files without external SRAM. Each EAB provides 4 Kbits of memory configurable as RAM, ROM, or dual-port RAM, and the four-input LUTs deliver 16x1 memory that can be cascaded into wider or deeper structures when needed.
Typical applications for the EP1K50XXC include peripheral bus bridging (PCI to local bus), glue logic for microcontroller and DSP co-processing, telecom line-card interface logic, industrial control state machines, and legacy ASIC replacement for low-to-medium volume production. The wide 5 V tolerant I/O simplifies interfacing to legacy TTL/CMOS logic without external level shifters.
When designing with the EP1K50XXC, ensure that the Quartus design tool is configured for the ACEX 1K device family, as newer Quartus versions have dropped support for this older family. Plan I/O bank assignments to match voltage requirements, and use the JTAG interface for in-system programming during prototype bring-up.

Aplicaciones típicas
EP1K50XXC es adecuado para 6 aplicacións: PCI Bus Bridge Logic, DSP Co-processor Glue Logic, Telecom Line Card Interface Logic, Industrial Control State Machines, Legacy ASIC Replacement, Test and Measurement Front-End Logic.
PCI Bus Bridge Logic
The EP1K50XXC's 2,880 logic elements and 5 V tolerant I/O are well-matched to legacy PCI bus bridge implementations. The 4,992-LE EP1K100 has been deployed as PCI-to-local bus bridges in industrial PCs; the EP1K50XXC fits smaller bus interfaces such as PCI-to-ISA or PCI-to-memory glue. With 333 maximum user I/O, the device accommodates full 32-bit data plus control signals plus local bus expansion. The dual-port EAB memory enables implementation of PCI transaction FIFOs without external SRAM. Designers should verify Quartus II 13.0sp1 support is retained for legacy PCI core IP.
Recomendado
DSP Co-processor Glue Logic
The EP1K50XXC serves as interface glue between microcontrollers/DSP processors and external peripherals, offloading parallel data formatting, address decoding, and timing-critical handshake logic. The 2,880 four-input LUTs handle 16-bit address decoding plus 32-bit data multiplexing comfortably. Embedded EAB memory provides small dual-port FIFOs for sample buffering between DSP serial ports and parallel peripherals. The 5 V tolerant I/O interfaces directly to legacy TTL peripherals without level shifters, simplifying board layout in mixed-voltage designs.
Recomendado
Telecom Line Card Interface Logic
Telecom line-card designs use the EP1K50XXC for TDM bus multiplexing, HDLC framing assist, and serial-to-parallel conversion. The device's 40 EABs of embedded memory (40 Kbits total) support small channel-assoc memory and time-slot lookup tables. Distributed logic elements handle TDM frame alignment and clock-domain crossing between backplane and line-side clocks. The industrial temperature grade (-40C to +85C) suits central-office deployments. Migration to MAX 10 or Lattice ECP5 is recommended for new line-card designs.
Recomendado
Industrial Control State Machines
Factory automation controllers benefit from the EP1K50XXC's logic density and embedded memory for sequencer implementations. The 2,880 LEs handle multi-axis motion controllers, sensor-fusion pre-processing, and serial-protocol bridging (Modbus, Profibus, CANopen glue). Industrial temperature grade supports deployment in factory-floor enclosures. EAB memory provides parameter storage for tuning constants without external EEPROM. Engineers maintaining legacy installations continue to deploy EP1K50 in field-replacement modules.
Recomendado
Legacy ASIC Replacement
The EP1K50XXC is a common drop-in replacement for low-to-medium volume ASIC designs in production today. Designers originally targeting 30-60K ASIC gates often prototype and produce with the EP1K50XXC, avoiding NRE charges. The 5 V tolerant I/O matches common 5 V ASIC libraries. Embedded EABs substitute for small ASIC-implemented ROM look-up tables. Risk-mitigation advantages include reprogrammability (re-spin for bugs is free) and second-source availability via EP1K100 upward migration.
Recomendado
Test and Measurement Front-End Logic
Instrumentation designers use the EP1K50XXC as front-end data routing, format conversion, and trigger logic in oscilloscopes, logic analyzers, and data-acquisition systems. The 40 EABs of dual-port RAM implement deep capture FIFOs between ADC data streams and downstream DSP or display engines. Multiple clock domains are supported via the device's flexible clock network. The combination of logic density, embedded memory, and 5 V tolerance accommodates legacy front-end circuitry while interfacing to modern 3.3 V processors.

Notas de diseño
Quartus Prime versions newer than 13.0sp1 do NOT support ACEX 1K devices including EP1K50XXC. Maintain a Quartus II 13.0sp1 installation in your tool repository for any maintenance or bitstream regeneration on existing EP1K50 designs. Migrating to Quartus Prime without checking legacy support will result in 'device not supported' errors that block bitstream generation entirely.
ACEX 1K devices support both 2.5 V and 3.3 V I/O bank voltages but require 5 V tolerant inputs via specific bank configuration. The EP1K50XXC's I/O banks must be assigned in Quartus II to match board-level voltage rails. Mismatched VCCIO bank voltages cause permanent I/O damage. Verify bank assignments against the schematic before generating the bitstream, and lock the pins (Assignments > Pin Planner) once validated.
FBGA-packaged EP1K50XXC variants require careful PCB thermal management. The 256-ball and 484-ball BGAs rely on thermal vias under the package for heat dissipation into inner copper planes. Use at least 9 thermal vias in a 3x3 array under the BGA center, connecting to a 1 oz copper inner ground plane. Without this thermal pad design, FBGA EP1K50 devices can exceed junction temperature limits at full I/O toggle utilization.
EP1K50XXC outputs have limited slew-rate control compared to modern FPGAs. When driving long PCB traces (>5 cm) or fast (>50 MHz) signals, add 22-33 ohm series termination resistors near the FPGA output pin. For clock outputs, place termination within 1 cm of the FPGA pin to prevent reflections. Multiple synchronous clock outputs should be routed with matched trace lengths to avoid skew in source-synchronous interfaces.
Información de cumplimiento
Original Altera EP1K50 devices shipped before 2006 typically non-RoHS; later RoHS-reflowed variants exist. Compliance varies by lot and date code. Verify with distributor for specific lot compliance status. Not AEC-Q100 qualified - ACEX 1K is not automotive-grade.
