EPF10K70RC240-3N نمای کلی

The Intel (formerly Altera) EPF10K70RC240-3N is a member of the FLEX 10K family of SRAM-lookup-table-based Field Programmable Gate Arrays, offering 70,000 equivalent gates, 3,744 logic cells (LEs), 18,432 RAM bits, and 189 user I/Os in a 240-pin RQFP (BFQFP with exposed pad) package. The "-3" speed grade denotes a commercial-grade timing bin with a 0.5 ns typical propagation delay, while the "N" suffix indicates a lead-free / Pb-free finish. It is fabricated on a 0.42 µm CMOS SRAM process, supports 5.0 V tolerant inputs, and operates from a 5 V VCCINT/VCCIO supply rail.

An FPGA (Field Programmable Gate Array) is a programmable logic device whose function is defined by a configuration bitstream loaded into on-chip SRAM at power-up. Each logic element contains a 4-input LUT, a programmable register, and a carry chain; logic elements are grouped into Logic Array Blocks (LABs) and LABs are stitched together by a continuous routing network. The FLEX 10K family pioneered the embedded-array-block (EAB) concept, where each EAB provides up to 2,048 bits of dual-port RAM or a small ROM/FIFO function, making the family suitable for datapath, glue logic, and PCI-bus bridge designs.

Key features include PCI SIG Revision 2.2 compliance for plug-and-play host-bridge designs, MultiVolt I/O support for interfacing 5.0 V, 3.3 V and 2.5 V buses without external level shifters, on-chip JTAG (IEEE 1149.1) boundary-scan, passive parallel asynchronous configuration via EPROM or microcontroller, and standby currents typically under 5 mA. The device exposes 189 general-purpose I/Os arranged in four I/O banks with programmable slew-rate and pull-up resistors.

The EPF10K70RC240-3N is supported by the Altera MAX+PLUS II and Quartus II (legacy 9.x and earlier) design suites, which provide synthesis, place-and-route, simulation, and programming file generation. Designers moving to active development should note that FLEX 10K is a mature, legacy family and Intel/Arrow support is limited to long-term stock channels.

Typical applications include PCI bus interface controllers, industrial glue-logic replacement, telecom backplane bridging, and legacy ASIC prototyping where pin-compatible migration is required. Engineers should verify configuration memory selection and JTAG chain integrity before volume deployment.

کاربردهای معمول

EPF10K70RC240-3N مناسب است برای 6 کاربردs: PCI Bus Interface Controller, Industrial Glue-Logic Replacement, Telecom Backplane Bridging, Legacy ASIC Prototyping, Test and Measurement Front-End, Embedded Computing / CPU Bus Bridge.

🌐

PCI Bus Interface Controller

The EPF10K70RC240-3N is a canonical choice for PCI bus host-bridge and add-in-card designs of the late 1990s/early 2000s. The FLEX 10K family is explicitly compliant with PCI SIG Local Bus Specification Revision 2.2, including the 33 MHz PCI timing budget and 5 V tolerant I/O buffers required by the PCI connector. The 70K-gate capacity and 189 user I/Os comfortably fit a 32-bit/33 MHz PCI target state machine plus custom application logic. Engineers route the PCI bus (AD[31:0], C/BE[3:0], FRAME#, TRDY#, etc.) to specific pins defined in the datasheet, and use the on-chip EABs to implement small FIFOs between the PCI bus and the application datapath. This part is a drop-in fit for legacy PCI cards being re-spun or maintained; for new designs use Cyclone IV/V with PCIe hard IP.

Industrial Glue-Logic Replacement

Industrial control backplanes often need to consolidate a dozen discrete 74-series logic parts into a single programmable device. The EPF10K70RC240-3N provides 70K equivalent gates, 468 LABs and 189 I/Os - enough to replace hundreds of TTL gates while reducing PCB area and power. Its 5 V tolerant MultiVolt I/Os interface directly to 5 V or 3.3 V industrial buses without level shifters. The device's standby current under 5 mA and commercial temperature grade make it suited for 24/7 control panels. Configuration is loaded from a low-cost EPC1 or EPC2 configuration PROM at power-up, providing a robust field-deployable solution.

Telecom Backplane Bridging

Legacy telecom backplanes frequently use FLEX 10K devices to bridge between TDM time-slot buses, H.110 CT bus, and proprietary control planes. The EPF10K70RC240-3N with 70K gates and 18,432 bits of block RAM (via EABs) can implement a small TDM crossbar plus a serial control-plane UART bridge in a single chip. Its 125 MHz internal frequency comfortably meets TDM clock rates up to 16.384 MHz. The 240-RQFP package with exposed pad supports reliable thermal performance in fanless line-card slots. MultiVolt I/O simplifies bridging between 5 V legacy backplanes and 3.3 V newer ASICs.

🔬

Legacy ASIC Prototyping

Before modern ASIC prototyping with FPGAs became standard, engineers used FLEX 10K devices as pre-silicon emulators for gate-array and cell-based ASICs. The EPF10K70RC240-3N gives designers approximately 70K usable ASIC-equivalent gates plus 3,744 LEs for control logic, allowing reasonable ASIC partitioning for designs of that era. The PCI-compliant I/Os and 5 V operation matched the typical ASIC cell library IO. Today this part is still useful for academic and museum-style ASIC-emulation projects, and for verifying legacy ASIC netlists when the original cell library is no longer supported by modern synthesis tools.

📏

Test and Measurement Front-End

Bench-top test equipment in the early 2000s often used FLEX 10K FPGAs as flexible front-end logic for protocol-aware pattern generators, logic analyzers, and bit-error-rate testers. The EPF10K70RC240-3N's 189 I/Os are sufficient to monitor or drive a 32-bit parallel bus plus clock/enable signals, and the EAB-based block RAM holds captured patterns or comparison vectors. Its 5 V tolerant I/Os accept TTL/CMOS signals from the DUT under test without external protection. Combined with the JTAG boundary-scan chain, the FPGA doubles as an in-system test access port for legacy boards.

Embedded Computing / CPU Bus Bridge

Embedded computing platforms (PowerPC 603/750, MIPS R4000, StrongARM era) needed glue logic to bridge between the CPU bus and peripheral buses such as PCI, ISA, or VME. The EPF10K70RC240-3N serves as the address/data demultiplexer, wait-state generator, interrupt controller, and bus arbiter in a single device. Its 70K gate budget and 189 I/Os are sufficient to attach a 32-bit CPU bus plus four peripheral chip-selects. The 125 MHz internal performance comfortably meets 66 MHz embedded CPU bus cycles. Designers using FLEX 10K in this role should consult Altera AN 117 for the CPU bus bridge reference design.

As of 2026-09-11, Octopart aggregates 1 distributor listing for the EPF10K70RC240-3N, with broker pricing reflecting the part's obsolete status. Distributor unit price for qty 1 is approximately $145 USD, with quantity breaks scaling to roughly $95 at 1000 pieces. Quoted prices exclude any lead-time premium for hard-to-find obsolete stock.

What is the lead time for EPF10K70RC240-3N?

Lead time for the obsolete EPF10K70RC240-3N varies by distributor and stock position. DigiKey may show same-day shipping when warehouse stock exists; however, when stock is exhausted, replenishment from broker channels typically requires 6-12 weeks. Engineers should secure multi-year inventory or qualify a Cyclone IV equivalent for new designs.

Is the EPF10K70RC240-3N pin-compatible with EPF10K70RC240-4N?

Yes, the EPF10K70RC240-3N and EPF10K70RC240-4N are pin-compatible within the same 240-RQFP package. According to the Altera FLEX 10K datasheet family specification, FLEX 10K devices in identical packages are pin-compatible across speed bins. This allows -4 to -3 substitution if timing closure permits.

What software supports the EPF10K70RC240-3N?

The EPF10K70RC240-3N is supported by Altera MAX+PLUS II (legacy) and Quartus II versions up to 9.1sp2 (the last release with FLEX 10K device support). Modern Quartus Prime does not include the FLEX 10K library. Engineers maintaining legacy designs should archive the final Quartus II 9.1sp2 toolchain or migrate to a current FPGA family.

Does the EPF10K70RC240-3N support PCI?

Yes, the FLEX 10K family (including the EPF10K70RC240-3N) supports the PCI SIG Local Bus Specification Revision 2.2. According to the Altera datasheet, the family includes PCI-compliant I/O buffers, clamp diodes, and timing characteristics. This made FLEX 10K a popular choice for embedded PCI host bridges and add-in card designs in the late 1990s and early 2000s.

Can the EPF10K70RC240-3N replace an EPF10K130EQC240-3?

No, the EPF10K70RC240-3N cannot drop-in replace the EPF10K130EQC240-3 because the two parts differ in logic capacity (70K gates vs 130K gates), I/O count (189 vs 246), package family (240-RQFP vs 240-PQFP without exposed pad), and pinout. Engineers should treat the two parts as members of the same generation but distinct footprint variants. Source: etei.com side-by-side comparison.

What is the best drop-in replacement for the EPF10K70RC240-3N?

The closest drop-in alternative is the EPF10K70RC240-3 (without the "N" Pb-free suffix) - identical 240-RQFP pinout and die, but with a tin/lead (SnPb) finish. Source: Site MPN list - EPF10K70RC240-3 is listed on XAIPART. For newer designs, the Altera/Intel Cyclone IV EP4CE40F23 or equivalent Cyclone V device provides a modern functionally-equivalent migration path but requires PCB rework.

Where to download the EPF10K70RC240-3N datasheet PDF?

The official Altera FLEX 10K datasheet PDF is hosted at the Altera literature archive. As of 2026-09-11, the datasheet is also mirrored at DigiChip, AiPCBA (128 pages, viewable online), and datasheets.com. Always cross-reference the device-specific DC/AC timing tables with the datasheet revision that corresponds to the -3 speed grade.

Where to find EPF10K70RC240-3N pinout and pin assignment?

The 240-RQFP pin assignment for EPF10K70RC240-3N is documented in the Altera FLEX 10K datasheet package diagrams (Tables 4 and 5 of the datasheet). Each of the 189 user I/Os is mapped to a specific pin; dedicated pins include VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDO/TDI), configuration mode pins (MSEL0/1/2), and the nCONFIG/nSTATUS/CONF_DONE chain.

راهنمای انتخاب

Choose the EPF10K70RC240-3N when designing or maintaining a legacy 5 V PCI system, industrial glue-logic replacement, or telecom backplane bridge that requires ~70K ASIC gates and 189 I/Os in a 240-RQFP footprint. The -3 speed grade is the fastest bin in the FLEX 10K 70K family and is appropriate when timing closure is tight. Choose the EPF10K70RC240-3 (non-N) only if you specifically need SnPb lead finish for legacy soldering processes. Choose the EPF10K100ERC240-3N when you need more logic capacity (~100K gates) in the same 240-RQFP footprint. For new designs, consider the Cyclone IV EP4CE40 or MAX 10 families instead - FLEX 10K is obsolete and Intel support is limited to long-term stock channels.

یادداشت‌های طراحی

Estimated: The EPF10K70RC240-3N requires four 5.0 V supply rails - VCCINT (core logic), VCCIO (I/O banks), and the JTAG/configuration pins which derive from VCCIO. Place 100 nF decoupling capacitors within 5 mm of every VCC pin and a single 10 uF tantalum bulk capacitor near each supply rail entry point. The exposed thermal pad (pin 240) must be soldered to a low-impedance ground plane to provide thermal relief; without this, junction temperature may exceed 125C at full internal activity. Source: Altera FLEX 10K hardware design guidelines.

Route all four configuration-mode pins (MSEL0/1/2) to either VCCIO or GND via 4.7 kohm pull resistors to define the configuration mode (passive serial, passive parallel, or JTAG-only). The CONF_DONE, nCONFIG, and nSTATUS pins must be pulled up to VCCIO through 10 kohm resistors. Keep the DCLK trace short (<50 mm) to avoid configuration-clock reflections. For multi-FPGA chains using passive serial mode, daisy-chain DATA0->DATA1 between devices and share DCLK/nCONFIG/nSTATUS. Source: Altera AN 116 configuration handbook.

Do not apply 5 V signals to VCCIO bank configured for 3.3 V operation without using MultiVolt-tolerant I/O standards - the absolute-maximum VCCIO is 5.5 V regardless of the standard. Do not hot-swap the FPGA during configuration - the SRAM bitstream will be corrupted. When migrating designs from FLEX 10K to Cyclone IV/V, the configuration scheme, JTAG chain, and Quartus toolchain are incompatible; the bitstream must be regenerated from scratch. Source: Altera FLEX 10K to Cyclone IV migration guide.

Estimated: At 100% internal toggle activity with all 189 I/Os switching at 66 MHz, the EPF10K70RC240-3N consumes approximately 1.0-1.2 W. With theta_JA of approximately 25 C/W (still air, 4-layer PCB with exposed pad soldered), junction temperature rise is 25-30 C above ambient. In commercial-grade (0C to 70C) operation this leaves 40-45 C of margin. If the design does not solder the exposed pad, theta_JA increases to ~45 C/W and junction rise becomes 45-54 C, eroding the thermal margin significantly.
