EPF10K10LC84-3 - FLEX 10K FPGA, 10K Gates, 84-LCC | Intel/Altera
MPN: EPF10K10LC84-3 ✗ Cuối đờiEPF10K10LC84-3 Tóm tắt
What is a FLEX 10K FPGA? The FLEX 10K (Flexible Logic Element matriX) family was the industry's first embedded programmable logic device family to provide System-on-a-Programmable-Chip (SOPC) integration. FPGAs in this hierarchy sit at the top of the programmable logic pyramid: PLD (programmable logic device) > CPLD (complex PLD) > FPGA (field-programmable gate array). Each FLEX 10K device embeds an array of logic elements (LEs), embedded array blocks (EABs) for memory/megafunctions, and a continuous routing fabric that allows large sequential and combinational designs to be implemented.
Key specifications include 6,144 typical gates / 10,000 maximum gates, 576 logic elements, 3 embedded array blocks providing up to 6,144 RAM bits, and a commercial operating temperature grade (0C to 70C). The -3 speed grade denotes the slowest of the FLEX 10K commercial speed bins, with a worst-case propagation delay around 0.6 ns per logic element in the datasheet's typical tables.
Architecturally, the FLEX 10K uses a CMOS SRAM-based configuration cell that must be loaded from a serial configuration EPROM at every power-up. Each embedded array block can be configured as a memory block or as a megafunction (FIFO, multiplier, adder) using Altera's MAX+PLUS II or Quartus toolchains. The MultiVolt I/O pins support PCI-clamping-diode, slew-rate control, and open-drain options on a pin-by-pin basis.
Typical applications include PCI bridge glue logic, peripheral bus interfaces, DSP co-processors, custom state machines, and legacy industrial control designs. Because the FLEX 10K family is end-of-life, the EPF10K10LC84-3 today is typically used for maintenance of legacy boards and second-source production. Designers should confirm long-term availability before specifying it in new designs.
When designing with this FPGA, verify configuration memory requirements: a single EPC2 or EPC1 configuration EPROM is sufficient for 10K-gate designs. JTAG boundary-scan is supported via the JTAG pins for board-level test. Pin migration between the 84-LCC package and the same die in 144-pin TQFP/QFP packages is possible because the silicon die is shared.

Ứng dụng tiêu biểu
EPF10K10LC84-3 phù hợp cho 6 Áp dụngs: Legacy PCI Bus Bridge / Glue Logic, DSP Co-Processor for Audio/Motor Control, Industrial Control State Machine / PLC Front-End, Custom Peripheral Expansion for Embedded CPUs, Telecom Line-Card Glue / Framing Logic, Legacy Test & Measurement Front-End.
Legacy PCI Bus Bridge / Glue Logic
The EPF10K10LC84-3 fits legacy PCI add-in card and motherboard designs because its MultiVolt I/O with optional PCI pull-up clamping diodes, slew-rate control, and 5.0 V VCCIO directly meet PCI 2.1 electrical specs. The 59 user I/O pins and 6,144 RAM bits are sufficient for small address/data multiplexers, interrupt controllers, and bus-master arbitration state machines that sit between a CPU and a PCI bus. With 576 logic elements and 10,000 typical gates, the FLEX 10K implements typical PCI 33 MHz bridge glue in a single device, eliminating two or three discrete TTL/CMOS helper chips on legacy boards.
Được đề xuất
DSP Co-Processor for Audio/Motor Control
The EPF10K10LC84-3's 3 embedded array blocks each contain 2,048 bits of dual-port RAM and can implement Altera megafunction multipliers, FIR filters, and accumulators for digital signal processing. With 576 logic elements for control sequencing, the device handles audio sample-rate conversion, simple motor-control PWM generation, or sensor-fusion pre-processing in legacy industrial controllers. The 5.0 V core and 3.3 V/5.0 V MultiVolt I/O allow direct interface to legacy audio DACs (such as the AD1854 or PCM1716) and 5 V motor-driver ICs without level shifters.
Được đề xuất
Industrial Control State Machine / PLC Front-End
The FLEX 10K's deterministic SRAM-based architecture and commercial 0C-70C temperature grade make the EPF10K10LC84-3 suitable for legacy industrial control front-ends that need fast, reprogrammable logic for sensor multiplexing, encoder quadrature decoding, or stepper-motor pulse trains. The 59 user I/Os can be software-assigned as inputs or outputs in any combination, supporting mixed signal flow without external bus switches. Engineers can update the configuration EPROM image to revise logic without re-spinning the PCB, ideal for long-lifecycle factory-automation equipment.
Được đề xuất
Custom Peripheral Expansion for Embedded CPUs
The EPF10K10LC84-3 pairs with 8-bit and 16-bit microcontrollers (8051, 68HC11, Z80) and 32-bit embedded processors to add custom peripherals such as additional UARTs, parallel I/O expanders, or proprietary bus interfaces. The 576 logic elements support FIFO buffers of up to 256 bytes per EAB plus glue logic for interrupt arbitration. SRAM-based configuration means the FPGA can be re-loaded at boot by the host CPU via serial configuration, eliminating a separate configuration EPROM in cost-sensitive designs.
Được đề xuất
Telecom Line-Card Glue / Framing Logic
In legacy telecom line cards, the EPF10K10LC84-3 implements HDB3/B8ZS encoding, framing/deframing state machines, and time-slot interchange between T1/E1 framers and backplane serializers. The 5.0 V core tolerates the long trace lengths typical of telecom backplanes, and the 3.3 V VCCIO option allows direct connection to newer CMOS PHYs. With 6,144 RAM bits spread across 3 EABs, the device holds small lookup tables for V.35 or HDLC bit stuffing without external memory.
Được đề xuất
Legacy Test & Measurement Front-End
The EPF10K10LC84-3's reprogrammability and 84-LCC J-lead footprint are valuable for legacy bench-top test instruments where the instrument must be field-upgradable but the PCB cannot be re-spun. Engineers use the FPGA to implement custom stimulus generators, parallel-pattern generators, or protocol decoders that can be revised by reprogramming the configuration EPROM. The JTAG boundary-scan support aids board-level test, and the 59 user I/O pins provide enough channels for small parallel test buses.

- Same FLEX 10K silicon die with -3 speed grade offers the lowest-cost entry point in the family (vsEPF10K10LC84-4)
- MultiVolt I/O with PCI clamping-diode logic option (vsOlder MAX 7000 CPLDs)
Ghi chú thiết kế
Estimated: VCCINT = 5.0 V at typical ICCINT of ~150 mA in a fully-utilized 10K design yields 750 mW core power. VCCIO at 5.0 V with 10 MHz toggling on 32 user I/Os adds roughly 200-400 mW. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic placed within 5 mm of the pin, plus a 10 uF bulk tantalum or ceramic at the package. Multiple GND pins (12, 29, 43, 60, 78 in this design) must all be connected to a low-impedance ground plane to avoid ground bounce during simultaneous switching.
The 84-LCC (J-Lead) package has 1.27 mm (50 mil) lead pitch with J-bend terminations that extend under the package body. PCB land pads should be 1.6 mm x 1.0 mm with the pad centerline offset 0.4 mm outside the package bodyline to allow proper solder fillet formation. A PLCC84 socket is recommended for prototyping because the FLEX 10K configuration can be re-loaded through a JTAG programmer without de-soldering the device. Maintain continuous ground plane on layer 2 with no splits beneath the device.
Estimated: configuration mode selection is critical. The FLEX 10K supports both passive serial (PS) and active serial (AS) modes - the EPF10K10LC84-3 with an EPC1/EPC2 EPROM uses active serial mode where the FPGA provides DCLK to the EPROM. A common mistake is leaving nCONFIG floating; it must be tied to VCCINT through a 10 kohm pull-up so the device enters configuration mode at power-up. CONFIG_DONE is open-drain and must be pulled up to VCCINT with a 10 kohm resistor. Do not exceed VCCIO above 5.25 V or below 3.0 V even momentarily during power sequencing, or the I/O buffers can latch up.
Thông tin tuân thủ
EPF10K10LC84-3 is a SnPb (leaded) terminal finish per FLEX 10K family production era. The Pb-free variants are the -3N/-4N suffix parts. RoHS compliance for the standard -3 part is non-compliant; check the specific lot/date code with the distributor for any exemption.
