EPF10K10AQC208-3 Présentation
An FPGA is a semiconductor device whose digital logic function is defined after manufacture by a customer-supplied configuration bitstream stored in external SRAM or an on-board PROM. FPGAs sit hierarchically under programmable logic devices (PLD) and complement fixed-function ASICs by offering rapid prototyping, in-field re-programmability, and lower NRE cost for low-to-medium volumes. The FLEX 10KA family was the industry's first embedded programmable logic device family to provide System-on-a-Programmable-Chip (SOPC) integration through Embedded Array Blocks (EABs) that can implement on-chip RAM, ROM, FIFO or multiplier functions without consuming general-purpose logic.
Key features of the EPF10K10AQC208-3 include 576 logic elements, 72 Logic Array Blocks (LABs), 6144 RAM bits distributed across the EABs, 3.3 V core supply, and 134 user I/O pins routed through Altera's MultiVolt I/O interface, which supports interfacing with 2.5 V, 3.3 V and 5 V devices on the same die. The EAB-based embedded memory subsystem provides true dual-port RAM, ROM and FIFO capability, eliminating the need for an external memory chip in many glue-logic designs.
Architecturally, the device is built on a 0.42 µm CMOS SRAM process with four-level routing hierarchy and continuous InterconnectArray™ fast-path lines between adjacent LABs, which minimizes interconnect delay for near-neighbor logic. Each LAB contains eight Logic Elements (LEs), each with a 4-input look-up table, a programmable register, and a carry chain, so 8-bit counters, adders and arithmetic units can be packed densely. Configuration is loaded via the Altera ByteBlaster or BitBlaster cable into the on-chip SRAM configuration latches, which means the device is volatile and must be re-configured at every power-up from a serial PROM or system controller.
Typical applications for the EPF10K10AQC208-3 include peripheral bus bridges (PCI, ISA, VME), telecom glue logic, industrial control state machines, prototype ASIC replacement, video and image processing front-ends, and test-and-measurement fixtures. Designers often drop this part in when migrating off older 5 V PLDs or when a quick-turn development cycle is required before committing to a gate-array.
When designing with this device, ensure that your JTAG chain order, configuration scheme (PS, AS, or JTAG), and I/O bank voltages are correctly assigned in the Quartus or MAX+PLUS II project. The 208-pin PQFP has a relatively large 30.6 mm body footprint with 0.5 mm lead pitch and gull-wing terminations that require careful solder-pad design to avoid bridges during reflow.

Applications typiques
EPF10K10AQC208-3 convient pour 6 applications: PCI/ISA Bus Bridge Glue Logic, Industrial Control State Machine, Prototype ASIC Replacement, Telecom Line-Card Glue Logic, Video / Image Processing Front-End, Test & Measurement Fixture Controller.
PCI/ISA Bus Bridge Glue Logic
The EPF10K10AQC208-3 is well suited to PCI/ISA bus-bridge glue-logic applications where 134 user I/Os, 576 logic elements, and 72 LABs provide enough capacity for address decoding, byte-enable generation, and interrupt steering. Its 3.3 V core with MultiVolt I/O allows direct interfacing to 5 V ISA peripherals while presenting a 3.3 V face to the PCI bus, eliminating external level shifters. The 6,144 bits of embedded RAM in EABs can be configured as FIFOs to buffer bus-master transfers, while the -3 speed grade easily meets the 33 MHz PCI timing budget at typical LUT depths. Designers typically drop this part into legacy bridge designs where re-validation cost of a newer Cyclone II device would exceed the BOM savings.
Recommandé
Industrial Control State Machine
In industrial control PLCs and motion controllers the EPF10K10AQC208-3 acts as a centralized state-machine host, sequencing digital I/O, PWM generators, and encoder counters while providing deterministic response within microseconds. Its commercial 0 °C to 70 °C range suits factory-floor enclosures, and the 208-PQFP gull-wing package survives vibration better than BGA alternatives. The 576 LEs comfortably fit ladder-logic interpreters, while the EABs provide parameter tables and lookup ROMs for motor calibration. The -3 speed grade's typical 0.6 ns LUT delay yields fMAX in the 100 MHz range for pipelined control loops.
Recommandé
Prototype ASIC Replacement
Before committing to a masked gate array, design teams use the EPF10K10AQC208-3 as an ASIC prototype to validate the RTL in real silicon, debug functional bugs, and run system integration tests on customer hardware. The FLEX 10KA fabric is fully re-programmable in seconds via JTAG, so multiple design revisions can be iterated without respin. The 208-PQFP has a development-friendly 0.5 mm pitch that can be hand-soldered or socketed, and the 134 user I/Os give enough margin to break out all ASIC signals for logic-analyzer probing. Once the design stabilizes, the RTL is simply re-targeted to a masked-array or structured-ASIC vendor using Quartus synthesis output.
Recommandé
Telecom Line-Card Glue Logic
In TDM/PDH telecom line cards the EPF10K10AQC208-3 implements HDLC controllers, alarm/status aggregation, and backplane bus multiplexing between framer, mapper and switch fabrics. The EAB-based dual-port RAM is ideal for elastic stores and jitter-attenuation FIFOs in T1/E1 tributaries, while the 134 I/Os handle dozens of serial control channels plus parallel backplane bus interfaces. The 3.3 V core with MultiVolt I/O bridges legacy 5 V framers and 2.5 V switch ASICs without external translation. Its 72 LABs and 576 LEs map well to typical line-card glue designs of 300-500 flip-flops and 100-150 combinational macros.
Recommandé
Video / Image Processing Front-End
The EPF10K10AQC208-3 is used as a pre-processor in cost-sensitive video capture boards, performing Bayer-to-YUV conversion, gamma correction, and frame-rate conversion before handing pixels to a downstream DSP or ASIC. The EABs hold 6,144 bits of embedded RAM which can be configured as line-buffers or lookup tables for gamma curves. With 134 I/Os the device can simultaneously accept parallel ITU-R BT.656 video, drive a 16-bit DDR memory bus, and provide I2C/SPI control channels. The -3 speed grade supports pixel clock rates up to ~80 MHz, sufficient for standard-definition and progressive VGA video pipelines.
Recommandé
Test & Measurement Fixture Controller
ATE fixture builders use the EPF10K10AQC208-3 as a flexible pattern generator, boundary-scan controller, and pin-electronics interface in custom ATE boards. The FLEX 10KA's reconfigurability lets a single fixture support multiple DUT families by simply re-loading a different bitstream over JTAG between test runs. The 208-PQFP gives easy access to 134 bidirectional channels for scan, parametric measurement, and analog mux control, while the 576 LEs implement pattern sequencers and result comparators. The EAB-based RAM stores golden signatures and per-DUT calibration tables.

Principaux différenciateurs
- Embedded Array Blocks (EABs) for on-chip RAM/ROM/FIFO (vs EPF10K10QC208-3)
- Drop-in faster speed grade in identical footprint (vs EPF10K10AQC208-2)
- Upward capacity headroom in same footprint (vs EPF10K20AQC208-3)
Notes de conception
Estimated: IccINT for the FLEX 10KA family is typically 5 mA standby plus 0.5-2 mA per MHz of internal toggle activity. At 50 MHz toggle rate and ~70 % utilization of the 576 LEs, expect IccINT ≈ 30-50 mA and IccIO up to ~20 mA per bank. Decouple each VCCINT pin with a 0.1 µF X7R ceramic plus a 10 µF tantalum bulk capacitor placed within 5 mm of the pin; provide one 0.1 µF cap per VCCIO bank pin to suppress simultaneous-switching noise on the 134 I/O pins.
Estimated: At maximum 33 MHz PCI utilization in a 208-PQFP with still air, the EPF10K10AQC208-3 dissipates under 0.5 W and stays well within the 0-70 °C commercial junction rating. The 208-PQFP θJA on a 4-layer test board is ~30 °C/W, giving a junction-to-ambient rise of only 15 °C at 0.5 W. No heatsink is required; however, locate the device away from high-current switching regulators to keep case temperature below 70 °C.
The 208-PQFP uses 0.5 mm pitch gull-wing leads on a 30.6 mm body footprint. Use a land pattern with 0.30 mm pad width and 0.25 mm length, with solder mask defined pads (NSMD) to improve rework yield. Route differential clock signals on the top layer over an unbroken ground plane and length-match within ±150 mil. Place the EPC1/EPC2 configuration PROM within 50 mm of the FLEX 10KA DCLK and DATA0 pins to keep configuration traces short and avoid ground-bounce during configuration.
Critical: 1) The FLEX 10KA is volatile - a missing or corrupted configuration PROM silently leaves all I/Os in tri-state at power-up, so always verify CONF_DONE goes high in production test. 2) Do not mix 5 V and 3.3 V signals on the same VCCIO bank without MultiVolt-compatible level translation - VCCIO sets the output VOH for the entire bank. 3) The -3 speed grade is the slowest FLEX 10KA bin; if timing closure fails at 33 MHz PCI, swap to a -2 speed grade (same package, drop-in). 4) Some early FLEX 10K silicon (no 'A' suffix) lacks EABs - do not migrate from a 10KA design to a 10K without porting out any embedded RAM blocks first.
Informations de conformité
RoHS compliance applies to the '-3N' terminal-finish variant; the bare EPF10K10AQC208-3 may have SnPb finish in older distributor stock. Not AEC-Q100 qualified - not suitable for automotive safety-critical applications.
