EPM7512BQC208-7 概述

The Altera EPM7512BQC208-7 is a MAX 7000B family Complex Programmable Logic Device (CPLD) with 512 macrocells, 10,000 usable gates, and 176 user I/O pins, housed in a 208-pin PQFP (28x28 mm) package and rated for commercial 0C to 90C operation. It operates from a 2.5 V core supply (2.375 V to 2.625 V) and delivers a maximum internal frequency of 90.1 MHz with a 7 ns pin-to-pin propagation delay.

A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines multiple logic blocks, macrocells, and a programmable interconnect array on a single die, allowing designers to implement custom digital logic without fabricating an ASIC. Within the logic IC hierarchy, a CPLD sits between simple PLDs (PAL/GAL) and FPGAs: CPLDs offer deterministic timing, non-volatile EEPROM configuration, and instant-on operation, while FPGAs provide higher logic density at the cost of external configuration memory. The MAX 7000B family is built on Altera's second-generation Multiple Array MatriX (MAX) architecture using high-performance 2.5 V CMOS EEPROM technology.

Key differentiators of the EPM7512BQC208-7 include its 512 macrocells (the highest density in the MAX 7000B family), 176 user I/O pins, 7 ns propagation delay, and EEPROM-based in-system programmability (ISP) that retains configuration without a battery or boot PROM. The 2.5 V core supply reduces dynamic power versus 5 V MAX 7000S devices while remaining tolerant of legacy 3.3 V system interfaces.

The device uses a Multiple Array MatriX architecture with logic array blocks (LABs) feeding a programmable interconnect array, giving predictable, fixed pin-to-pin delays independent of routing. Each macrocell provides programmable flip-flops, product-term logic, and I/O registers, enabling state machines, bus interfaces, and glue logic to be integrated into one device.

Typical applications include legacy industrial control boards, PCI/ISA bus bridging, address decoding and chip-select generation, instrumentation glue logic, and replacement of discrete 74-series logic. The 208-pin PQFP footprint is shared across the MAX 7000B family, allowing density migration without PCB redesign.

When designing with this CPLD, note that the -7 speed grade is the fastest commercial grade in the family; the -10 and -15 grades trade speed for lower cost. Because the device is EEPROM-based, it is configured at power-up with no external configuration device, simplifying board bring-up compared with SRAM-based FPGAs.

This page synthesizes distributor availability, drop-in speed-grade alternatives, and practical design notes for the EPM7512BQC208-7 that are not consolidated in the manufacturer datasheet.

EPM7512BQC208-7 适用于 6 应用s: Legacy Industrial Control Boards, PCI/ISA Bus Bridging and Interface Logic, Instrumentation Glue Logic and Address Decoding, Replacement of Discrete 74-Series Logic, Test and Measurement Equipment Control, Legacy Board Repair and Obsolescence Management.

🏭

Legacy Industrial Control Boards

The EPM7512BQC208-7 fits legacy industrial control boards because its 512 macrocells and 176 user I/O pins can absorb the discrete 74-series glue logic, address decoders, and state machines that populate older controller cards. Its 2.5 V core and EEPROM-based configuration mean the board powers up instantly with no external configuration PROM, which matters in factory equipment that must resume operation immediately after a power interruption. The 7 ns pin-to-pin delay and 90.1 MHz internal frequency provide deterministic timing for handshake and interlock logic. Because the 208-pin PQFP footprint is shared across the MAX 7000B family, a board can be re-spun with a different density without changing the land pattern. The main trade-off is that the 2.5 V core requires a dedicated regulator rail alongside legacy 5 V and 3.3 V supplies.

PCI/ISA Bus Bridging and Interface Logic

The EPM7512BQC208-7 is well suited to PCI and ISA bus bridging because its 176 user I/O pins can directly interface a 32-bit local bus to peripheral devices while implementing wait-state generation, byte swapping, and chip-select decoding in programmable logic. The 7 ns propagation delay supports the tight setup and hold windows of legacy parallel buses, and the 512 macrocells provide enough product terms for complex address decode without external PALs. EEPROM configuration means the bridge logic is live immediately at power-up, avoiding the configuration latency of SRAM-based FPGAs. Designers should note that the 2.5 V core requires level shifting when interfacing 5 V PCI signaling, and that the -10 speed grade may be marginal for the fastest bus cycles, making the -7 grade the safer choice for full-speed operation.

Instrumentation Glue Logic and Address Decoding

In instrumentation designs the EPM7512BQC208-7 consolidates address decoding, chip-select generation, and read/write strobe logic that would otherwise require dozens of 74-series packages. Its 512 macrocells allow multiple peripheral decoders to be implemented in one device, reducing board area and improving reliability by eliminating inter-package routing. The 7 ns pin-to-pin delay keeps decode paths short enough for fast microprocessor buses, and the 90.1 MHz internal frequency supports simple state machines for ADC/DAC sequencing. Because the device is EEPROM-based, calibration and configuration data are retained without a battery. The trade-off is static power: the 2.5 V CMOS core draws quiescent current even when idle, so battery-powered instruments should evaluate the power budget carefully.

Replacement of Discrete 74-Series Logic

The EPM7512BQC208-7 replaces large banks of discrete 74-series logic by integrating counters, shift registers, multiplexers, and glue gates into a single 208-pin PQFP device. With 512 macrocells and 176 user I/O pins, a single CPLD can absorb the equivalent of dozens of SSI/MSI packages, shrinking board area and reducing assembly cost. The 7 ns propagation delay is comparable to fast 74-series logic, so timing behavior is preserved, and the EEPROM configuration means no boot device is needed. Engineers migrating from discrete logic should account for the 2.5 V core supply and the need to re-verify timing closure, since CPLD routing introduces fixed but nonzero delays that differ from discrete gate propagation.

Test and Measurement Equipment Control

The EPM7512BQC208-7 is used in test and measurement equipment to implement trigger logic, timing generators, and instrument control state machines. Its 90.1 MHz internal frequency and 7 ns pin-to-pin delay allow precise event sequencing, while 176 user I/O pins can drive front-panel controls, relays, and measurement front ends directly. The non-volatile EEPROM configuration ensures the instrument is operational immediately at power-on, which is important for automated test cells that cannot wait for FPGA configuration. Because the MAX 7000B family is an older line, designers should plan for long-term supply by stocking the -7 grade or qualifying the pin-compatible -10 grade as a fallback for non-critical timing paths.

Legacy Board Repair and Obsolescence Management

The EPM7512BQC208-7 is frequently sourced for repair and obsolescence management of legacy boards where the 208-pin PQFP footprint is fixed and redesign is not economical. Because the MAX 7000B family is no longer in active production, the -7 grade is obtained through independent and aftermarket channels, and buyers should verify date codes and authenticity. The pin-compatible EPM7512BQC208-10 and EPM7512BQC208-5 grades provide fallback options when the -7 is unavailable, since all three share the same die and package. For long-term support, engineers should archive the original JEDEC programming file and confirm that any substitute grade still meets the board's timing margins before committing to volume purchases.

What is the EPM7512BQC208-7?

The EPM7512BQC208-7 is a MAX 7000B family CPLD from Altera with 512 macrocells, 10,000 usable gates, and 176 user I/O pins in a 208-pin PQFP package. It runs from a 2.5 V core supply and is rated for commercial 0C to 90C operation. The -7 suffix denotes the 7 ns pin-to-pin propagation delay speed grade, the fastest commercial grade in the MAX 7000B family.

What are the key specifications of EPM7512BQC208-7 that engineers should know?

The EPM7512BQC208-7 offers 512 macrocells, 10,000 usable gates, 176 user I/O pins, 90.1 MHz maximum internal frequency, and 7 ns propagation delay, all in a 208-pin PQFP (28x28 mm) package. Core supply is 2.375 V to 2.625 V (2.5 V nominal). It is EEPROM-based and in-system programmable, so configuration is retained without an external boot device. These figures come from distributor and manufacturer product data for the MAX 7000B family.

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

The EPM7512BQC208-7 and EPM7512BQC208-10 are the same MAX 7000B CPLD die in the same 208-pin PQFP package; the only difference is the speed grade. The -7 part has a 7 ns pin-to-pin propagation delay, while the -10 part is rated at 10 ns. Both have 512 macrocells, 176 user I/Os, and 2.5 V core supply. The -7 is faster and typically more expensive; the -10 is a valid drop-in when timing margin allows.

Is EPM7512BQC208-10 a drop-in replacement for EPM7512BQC208-7?

Yes, the EPM7512BQC208-10 is a pin-to-pin drop-in replacement for the EPM7512BQC208-7 because both use the identical 208-pin PQFP package and the same MAX 7000B die. The only trade-off is speed: propagation delay increases from 7 ns to 10 ns and maximum internal frequency drops accordingly. Verify that your design's critical timing paths still close at the slower grade before substituting.

What is the best drop-in replacement for EPM7512BQC208-7?

The best drop-in replacement for the EPM7512BQC208-7 is the EPM7512BQC208-10, which shares the same 208-pin PQFP footprint and MAX 7000B architecture but is one speed grade slower (10 ns vs 7 ns). If your design has timing margin, this is a direct board-level swap. The EPM7512BQC208-5 is the faster alternative if you need more timing headroom, though it is a less common grade.

Where to buy EPM7512BQC208-7 online?

The EPM7512BQC208-7 is listed by distributors including DigiKey, Mouser, and Octopart, and by independent stockists such as Rochester Electronics, Jotrin, and Veswin. Because the MAX 7000B family is an older Altera/Intel product line, availability is increasingly limited to independent and aftermarket channels. Always confirm authenticity and date code before purchasing from non-authorized sources, and request a Certificate of Conformance where possible.

What is the price of EPM7512BQC208-7?

Pricing for the EPM7512BQC208-7 is not published as a fixed catalog price in the verified data; it is quoted per distributor and varies with stock, date code, and quantity. As of 2026-09-13, Octopart aggregates offers from multiple distributors for this part, and DigiKey lists it under part number EPM7512BQC208-7. Request a live quote for current pricing, since obsolete CPLD pricing fluctuates with remaining inventory.

What is the lead time for EPM7512BQC208-7?

Lead time for the EPM7512BQC208-7 depends entirely on distributor stock because the MAX 7000B family is no longer in active production. Authorized-channel inventory is limited, so most orders ship from existing stock rather than a factory lead time. Independent distributors may quote days to weeks depending on availability. For production planning, secure buffer stock early and qualify a drop-in speed-grade alternative such as the EPM7512BQC208-10.

Is EPM7512BQC208-7 in stock?

Stock for the EPM7512BQC208-7 varies by distributor and changes frequently because the part is an older MAX 7000B CPLD. Octopart reports multiple distributor listings, and DigiKey and Mouser both carry product pages for the part. Because inventory is not guaranteed, check live stock at the time of order and consider the EPM7512BQC208-10 or EPM7512BQC208-5 as pin-compatible fallbacks if the -7 grade is unavailable.

What is the difference between EPM7512BQC208-7 and EPM7512BQC208-5?

The EPM7512BQC208-7 and EPM7512BQC208-5 are the same MAX 7000B CPLD in the same 208-pin PQFP package, differing only in speed grade. The -5 grade is faster (5 ns propagation delay) than the -7 grade (7 ns). Both have 512 macrocells and 176 user I/Os. The -5 is the premium speed grade and is typically scarcer and more expensive; the -7 is the mainstream fast grade.

When should I choose EPM7512BQC208-7 over EPM7512BQC208-10?

Choose the EPM7512BQC208-7 when your design's critical timing paths require a 7 ns pin-to-pin delay or operation near 90 MHz, and the 10 ns grade would violate setup/hold margins. If your logic runs well below 90 MHz with comfortable timing slack, the EPM7512BQC208-10 is the more cost-effective and more available choice. Both are pin-identical, so the decision is purely a timing-versus-cost trade-off.

Is EPM7512BQC208-7 suitable for new designs?

The EPM7512BQC208-7 is generally not recommended for new designs because the MAX 7000B family is an older Altera/Intel CPLD line with limited long-term supply. For new projects, a modern low-cost CPLD or small FPGA with a migration path is preferable. However, the EPM7512BQC208-7 remains suitable for sustaining existing boards, legacy industrial equipment, and drop-in repair where the PCB footprint is fixed.

Where to download EPM7512BQC208-7 datasheet PDF?

The EPM7512BQC208-7 datasheet is available from the Intel/Altera product page and from distributor and aggregator sites such as DigiKey, Mouser, FindIC, and FPGAkey. The MAX 7000B family datasheet covers the EPM7512B device, including the 208-pin PQFP pinout, DC electrical characteristics, and timing models. Always download from the manufacturer or an authorized distributor to ensure you have the current revision.

Where to find EPM7512BQC208-7 pinout?

The EPM7512BQC208-7 pinout is documented in the MAX 7000B family datasheet, which lists all 208 PQFP pins including the 176 user I/O pins, dedicated VCCINT and VCCIO power pins, ground pins, and JTAG programming pins. Distributor pages such as DigiKey and Mouser link to the same datasheet. Because the 208-pin PQFP footprint is shared across the MAX 7000B family, the pinout is identical for the -5, -7, and -10 speed grades.

What is the best Altera equivalent for EPM7512BQC208-7?

The best Altera equivalent for the EPM7512BQC208-7 is the EPM7512BQC208-10, which is the same MAX 7000B device in the same 208-pin PQFP package at a slower 10 ns speed grade. If you need a faster part, the EPM7512BQC208-5 is the premium grade. All three share the identical die and pinout, so they are interchangeable at the board level subject to timing verification.

Is EPM7512BQC208-7 the same as EPM7512BQC208-10?

No, the EPM7512BQC208-7 and EPM7512BQC208-10 are not identical parts, but they are the same device in the same package at different speed grades. The -7 has a 7 ns pin-to-pin propagation delay and the -10 has a 10 ns delay. Both have 512 macrocells, 10,000 usable gates, 176 user I/O pins, and a 2.5 V core supply in a 208-pin PQFP. They are pin-to-pin interchangeable subject to timing verification.

选型指南

Choose the EPM7512BQC208-7 when you need the fastest commercial MAX 7000B CPLD in a 208-pin PQFP footprint, particularly for legacy bus bridging or state machines running near 90 MHz where a 10 ns delay would violate timing. Choose the EPM7512BQC208-10 if your design has comfortable timing slack and you want the more available, lower-cost speed grade; it is pin-identical and drops into the same socket. Choose the EPM7512BQC208-5 only if you need additional timing headroom and can source the scarcer premium grade. Avoid the EPM7512BFC256-7 unless your board already uses the 256-pin FBGA footprint, since it is not land-pattern compatible with the PQFP. For new designs, consider a modern CPLD or small FPGA instead, as the MAX 7000B family is an older line with limited long-term supply.

设计说明

The EPM7512BQC208-7 requires a 2.5 V core supply within 2.375 V to 2.625 V. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible, plus at least one 10 uF bulk capacitor per supply rail. Because the MAX 7000B core is CMOS, dynamic current scales with switching frequency and the number of toggling macrocells; estimate the worst-case ICC from the datasheet ICC vs frequency curve and size the regulator with at least 30% margin. Do not share the 2.5 V rail with noisy switching regulators without additional LC filtering.

The 208-pin PQFP has a 0.5 mm lead pitch, so use a solder mask-defined land pattern and reflow profile per the manufacturer datasheet. Route all VCCINT and VCCIO pins to solid power planes rather than daisy-chaining, and place a 0.1 uF decoupling capacitor within 2 mm of every power pin. Keep the JTAG signals (TCK, TMS, TDI, TDO) short and referenced to a continuous ground plane; TCK in particular should be treated as a clock net with controlled impedance to avoid programming failures. Provide a ground via adjacent to each decoupling capacitor.

A common mistake when substituting speed grades is assuming the -10 part will always work in a -7 socket. The EPM7512BQC208-10 is pin-compatible but 43% slower in pin-to-pin delay (10 ns vs 7 ns), so any design operating near the 90.1 MHz limit or with tight external bus timing may fail. Always re-run static timing analysis with the slower grade's derated tPD and tSU/tCO values before committing to a substitution. Also verify that the programming file targets the correct device density, since the MAX 7000B family shares a footprint but not a JEDEC file across densities.
