EPM7512BQC208-10 جائزہ

The Altera (Intel) EPM7512BQC208-10 is a high-density, in-system-programmable Complex Programmable Logic Device (CPLD) from the MAX 7000B family, featuring 512 macrocells, 10,000 usable gates, 176 user I/Os, and a 10 ns pin-to-pin propagation delay, housed in a 208-pin Plastic Quad Flat Pack (PQFP-208, 28x28 mm) package.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a central interconnect matrix. CPLDs sit between simple SPLDs and FPGAs in the programmable-logic hierarchy, providing fast, deterministic pin-to-pin timing (no boot time), instant-on operation, and EEPROM- or flash-based configuration that retains the bitstream across power cycles. The MAX 7000B family specifically is built on a 2.5 V CMOS EEPROM Multiple Array Matrix (MAX) architecture and was designed as a glue-logic replacement for multiple 74-series TTL parts.

Key features of the EPM7512BQC208-10 include 32 Logic Array Blocks (LABs) of 16 macrocells each, four pin-to-pin output enable signals, in-system programmability through a JTAG-compliant IEEE Std. 1149.1 interface, and a commercial operating temperature grade of 0 to +70 degrees C. The device operates from an internal 2.5 V core supply (2.375 V to 2.625 V) and is supported by the legacy Altera MAX+PLUS II and Quartus II design software.

Architecturally, the MAX 7000B device uses a second-generation MAX architecture with a programmable interconnect array (PIA) that routes signals between LABs. Each macrocell contains a programmable AND/OR array, a flip-flop, and configurable I/O architecture supporting JTAG boundary-scan testing, which simplifies board-level test in production. The -10 speed grade places this part at the slower end of the MAX 7000B range, trading off fmax for reduced cost and easier timing closure in glue-logic applications.

Typical applications include bus-interface bridging, address decoding, state-machine control, peripheral glue logic, industrial I/O expansion, and legacy 5 V/3.3 V system interfacing where the MAX 7000B I/O tolerance is required. The 176 user I/O count is generous for replacing many discrete 74LS/74HC packages with a single device.

When designing, note that the EPM7512BQC208-10 is part of the mature MAX 7000B line: many MAX 7000B variants are now NRND or EOL, so check the latest lifecycle status before committing to a new design. The 208-pin PQFP package requires careful PCB layout, with thermal and high-speed signal-integrity considerations; XAIPART can cross-reference compatible MAX 7000B speed grades (e.g., -7, -10, -12, -15) that share this PQFP-208 footprint.

Address Decoding and Bus Bridging

The EPM7512BQC208-10 is widely used in microprocessor-based systems for address decoding, chip-select generation, and bus-bridging between asynchronous bus domains. The 10 ns pin-to-pin delay is well within the address-to-CS timing budget of most 33-50 MHz microcontrollers and embedded MPUs. With 176 user I/Os and 512 macrocells, a single EPM7512B can replace dozens of 74LS138/139/32 decoders and '245 transceivers, simplifying PCB layout and reducing BOM cost. The in-system programmability allows last-minute address map changes without board rework.

State Machine and Control Logic

The 512 macrocells and 32 LABs of the EPM7512BQC208-10 provide ample capacity for implementing complex multi-state control machines, sequencers, and protocol controllers. Each macrocell contains a flip-flop and configurable AND/OR array, making it efficient for Moore and Mealy state machines with up to 50-60 states. The deterministic 10 ns timing makes timing closure predictable for safety-critical industrial control applications, and the EEPROM-based configuration retains state-machine definition across power cycles without boot time.

Legacy Peripheral Glue Logic

Many legacy embedded designs still require the EPM7512BQC208-10 to integrate asynchronous peripherals such as UARTs, parallel ports, SCSI controllers, and IDE interfaces. The fast 10 ns tpd and abundant I/O allow timing-critical handshake signal generation without resorting to discrete 74FCT or 74AVC logic. The in-system programming feature means firmware teams can iterate on glue-logic fixes without respinning the PCB - a major advantage over traditional TTL PAL/GAL designs.

Telecommunications Backplane Bridging

In telecom backplanes, the EPM7512BQC208-10 serves as a low-latency protocol bridge between legacy TDM buses and modern packet interfaces. The deterministic 10 ns timing ensures that timing-critical TDM frame pulses and clock-domain crossings meet jitter requirements. With 176 user I/Os, a single part can interface to multiple line-card slots, eliminating a fanout tree of buffers. The 208-pin PQFP package is well-suited to through-hole backplane daughter-card assemblies.

Test and Measurement Equipment Front-End

The EPM7512BQC208-10's deterministic timing and abundant I/O make it a useful front-end controller for legacy test and measurement equipment such as benchtop oscilloscopes, logic analyzers, and ATE fixtures. It can implement custom timing generators, scan-chain controllers, and front-panel I/O expanders while maintaining repeatable 10 ns timing margins. JTAG boundary scan allows production-board self-test, reducing fixture complexity in mixed-signal ATE systems.

What is the EPM7512BQC208-10?

The EPM7512BQC208-10 is an Altera (Intel) MAX 7000B family Complex Programmable Logic Device (CPLD) with 512 macrocells, 10,000 usable gates, 176 user I/Os, and a 10 ns maximum pin-to-pin propagation delay, supplied in a 208-pin PQFP package. It is in-system programmable via JTAG and operates from a 2.5 V internal supply, with a commercial 0 C to +70 C temperature grade. The part is listed as Not Recommended for New Designs (NRND) per the Altera/Intel product lifecycle.

How many user I/O pins does the EPM7512BQC208-10 have?

The EPM7512BQC208-10 provides 176 user I/O pins. According to the Altera MAX 7000B datasheet, this is the maximum I/O count for the 208-pin PQFP package variant of the EPM7512B. The I/Os are organized around 32 Logic Array Blocks (LABs) and support per-pin configurable slew rate, pull-up resistors, and open-drain output modes for flexible system integration.

What is the difference between EPM7512BQC208-10 and EPM7512BQC208-7?

Both parts share the same 512-macrocell MAX 7000B die and 208-pin PQFP package, but the EPM7512BQC208-7 is the faster 7 ns speed grade while the EPM7512BQC208-10 is the 10 ns speed grade. The -7 variant delivers higher fmax at higher cost; the -10 variant offers identical functional behavior with looser timing margins, making it suitable for cost-sensitive glue-logic designs. Pinout and footprint are identical, so they are drop-in compatible.

Where can I buy the EPM7512BQC208-10 online?

The EPM7512BQC208-10 is available from authorized distributors including DigiKey (stocked by Rochester Electronics), Mouser, and several independent distributors, as of 2026-09-13. Because the part is NRND with the original Altera supply chain, expect pricing in the $19-30 range per unit and lead times of 4-8 weeks from independent distributors. For new designs, consider active MAX II or MAX V CPLD alternatives from Intel.

What is the price of the EPM7512BQC208-10?

Distributor pricing for the EPM7512BQC208-10 as of 2026-09-13 ranges from approximately $19.40 at qty 500 to $28.50 at qty 1 on the open market. Because the part is NRND with limited authorized stock, Rochester Electronics holds the franchised inventory and independent distributors typically quote higher unit prices reflecting component scarcity. Request a live quote for current pricing and availability.

Is the EPM7512BQC208-10 still in production?

No, the EPM7512BQC208-10 is classified as Not Recommended for New Designs (NRND) by Altera/Intel. Original Altera production has been transferred to Rochester Electronics for ongoing fulfillment of legacy orders. For new designs, Intel recommends the MAX II, MAX V, or MAX 10 CPLD families, which offer higher density, lower power, and active product roadmaps.

What is the maximum operating frequency of the EPM7512BQC208-10?

The EPM7512BQC208-10 is specified with a maximum pin-to-pin propagation delay (tpd) of 10 ns, which corresponds to a maximum toggle frequency of roughly 100 MHz for registered logic, depending on the design. Internal counter frequencies can exceed this when the global clock network is used, but synchronous design at 100+ MHz requires careful timing closure with MAX+PLUS II or Quartus II timing reports.

What package does the EPM7512BQC208-10 use?

The EPM7512BQC208-10 is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package measuring 28 x 28 mm with a 0.5 mm pitch (JEDEC package code S-PQFP-G208). The PQFP-208 is a through-hole-friendly surface-mount package with gull-wing leads. Care must be taken during PCB layout to route all 176 user I/O signals, four JTAG pins, and dedicated programming pins out from the dense pin field.

Can I program the EPM7512BQC208-10 in-system?

Yes, the EPM7512BQC208-10 supports in-system programming (ISP) through its JTAG-compliant IEEE Std 1149.1 interface. A standard JTAG header (TCK, TMS, TDI, TDO plus TRST) can be used with the ByteBlasterMV or USB-Blaster download cable and the Altera MAX+PLUS II or Quartus II programmer. ISP allows field firmware updates without removing the device from the board.

What software tools support the EPM7512BQC208-10?

The EPM7512BQC208-10 is fully supported by Altera's MAX+PLUS II (legacy) and Quartus II design software (version 13.0 and earlier). Quartus II provides synthesis, place-and-route, timing analysis, simulation, and programming file generation. For new projects targeting this part, use the latest Quartus II 13.0sp1 build, which is the final release that includes MAX 7000B device support.

What is the best drop-in replacement for the EPM7512BQC208-10?

The best drop-in replacement for the EPM7512BQC208-10 is the EPM7512BQC208-7, which shares the same 208-pin PQFP footprint, the same 512 macrocell density, and the same MAX 7000B die, with only a faster 7 ns tpd. Other drop-in alternatives include the EPM7512BQC208-12 and EPM7512BQC208-15, all sharing the same S-PQFP-G208 footprint. For pin-compatible cross-brand options, see the alternatives section below.

EPM7512BQC208-10 vs EPM7512AEQI208-10 - which is better?

The EPM7512BQC208-10 belongs to the MAX 7000B family with a 2.5 V core and a 10 ns tpd, while the EPM7512AEQI208-10 belongs to the older MAX 7000A family with a 3.3 V core and a 10 ns tpd in an industrial temperature grade. They share the 208-pin PQFP package and 512 macrocells, but the 'A' part operates at 3.3 V and the 'B' part at 2.5 V, so they are not drop-in compatible. Choose the 'B' variant for newer 2.5 V designs and the 'A' variant for legacy 3.3 V systems.

What are the key specifications of EPM7512BQC208-10 that engineers should know?

The EPM7512BQC208-10 key specifications are: 512 macrocells, 32 Logic Array Blocks (LABs), 10,000 usable gates, 176 user I/Os, 10 ns pin-to-pin propagation delay, 2.375-2.625 V internal supply (2.5 V nominal), 0 C to +70 C commercial operating temperature, 208-pin PQFP (28x28 mm) package, in-system programmable via JTAG (IEEE 1149.1), and CMOS Multiple Array Matrix (MAX) second-generation architecture.

انتخاب کی گائیڈ

Choose the EPM7512BQC208-10 when you need a high-density (512 macrocells, 176 user I/Os) MAX 7000B CPLD with 10 ns timing for general-purpose glue logic at 50 MHz or below, and you are maintaining or repairing a legacy design that already uses this PQFP-208 footprint. Choose the EPM7512BQC208-7 if your design needs faster 7 ns timing for tighter setup margins at higher clock rates. Choose the EPM7512BQC208-12 or -15 for lowest-cost applications where timing closure is not critical. For new designs, prefer the active Intel MAX II or MAX V CPLD families, which offer higher density, lower power, modern Quartus Prime support, and ongoing silicon availability. Note that all MAX 7000B speed grades share the same PQFP-208 footprint, so PCB layout can be reused across the family.

ڈیزائن نوٹس

The 208-pin PQFP package (0.5 mm pitch, 28x28 mm body) demands a 4-layer PCB minimum with continuous VCC and GND planes under the device to provide low-impedance power delivery to all 176 user I/Os. Route high-speed signals (e.g., clock, JTAG) on inner layers with reference to ground, and keep I/O traces short to minimize crosstalk. Estimated: with 4-layer stack-up and 1 oz copper, expect approximately 0.5-1.0 C/W thermal resistance improvement over a 2-layer board.

Although the EPM7512BQC208-10 has a 10 ns tpd, simultaneous-switching outputs (SSO) can cause ground bounce on heavily-loaded output banks. Distribute switching outputs across multiple I/O banks, and add 22-33 ohm series-termination resistors on outputs driving more than 2 inches of trace or more than 2-3 loads. JTAG signals (TCK, TMS, TDI, TDO) should be kept short and guarded to ground for reliable boundary-scan operation at 10-20 MHz TCK frequencies.

Critical: do not confuse the EPM7512BQC208-10 (MAX 7000B, 2.5 V core) with the older EPM7512AQC208-10 (MAX 7000A, 3.3 V core) - the VCCINT supply differs (2.5 V vs 3.3 V) and the parts are NOT drop-in compatible at the supply level. Also note that the part is NRND with the original Altera supply chain now served by Rochester Electronics; for new designs, consider the Intel MAX II (EPM240/EPM570/EPM1270) or MAX V (5M40ZE64/5M80ZE64) families. Verify the JTAG IDCODE in your programming chain to detect mis-programming attempts.

The PQFP-208 package has a junction-to-ambient thermal resistance (theta_JA) of approximately 30-35 C/W on a standard 4-layer JEDEC test board. The CMOS MAX 7000B core draws only a few hundred milliamps, so self-heating is modest (typically <0.5 W). Estimated: at 70 C ambient, junction temperature stays below 90 C under normal conditions, well within the commercial 0-70 C operating range. For enclosed industrial enclosures, verify airflow keeps ambient below 60 C.
