EPM3512AQI208-7 Visão geral

The Altera (Intel) EPM3512AQI208-7 is a member of the MAX 3000A Complex Programmable Logic Device (CPLD) family, delivering 10,000 usable gates with 512 macro cells and a 116.3 MHz internal performance grade, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates from a 3.3 V core supply and supports 2.5 V, 3.3 V, or 5.0 V I/O operation through separate VCCINT and VCCIO rails.

A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EPROM-based programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy: simple PLD < CPLD < FPGA. Compared with FPGAs, CPLDs offer deterministic timing (typically 5-10 ns pin-to-pin), instant-on non-volatile configuration, and very low standby power, which makes them well suited for glue logic, bus decoding, and power-sequencing tasks in larger systems.

Key features of the EPM3512AQI208-7 include 512 macro cells (arranged in 16 Logic Array Blocks of 32 cells each), 100% non-volatile in-system programmability compliant with the IEEE Std. 1532 ISP specification, 3.3 V core operation with multi-voltage I/O support, and a speed grade of -7 which delivers a tPD (pin-to-pin delay) of approximately 7.5 ns and an fCNT toggle rate around 116.3 MHz. The device integrates JTAG boundary-scan support and a 4-pin JTAG interface for ISP.

Architecturally, the EPM3512AQI208-7 uses an EPROM-based programmable interconnect matrix (PIA) and product-term macro cells - a classic MAX-style architecture that has shipped in hundreds of millions of units since the mid-1990s. Its non-volatile bit cells retain logic configuration without external boot memory, which simplifies board layout and BOM cost versus SRAM-based FPGAs.

Typical applications include industrial control glue logic, address decoding and bus interfacing for legacy microprocessors, power-supply sequencing in multi-rail systems, peripheral expansion in 8051/PIC-based designs, and prototyping interfaces for ASIC emulation. The PQFP-208 footprint also allows hand-soldering and socketed prototyping, which is rarely possible with modern fine-pitch BGA packages.

When designing with this device, ensure that both VCCINT (3.3 V) and VCCIO (2.5 V / 3.3 V / 5.0 V) rails are properly decoupled with 0.1 uF and 10 uF capacitors placed close to the pins. The MAX 3000A is mature and in NRND/EOL transition for many variants, so design for second-source availability within the same PQFP-208 footprint (such as the EPM3512AQC208-7 family).

Aplicações típicas

EPM3512AQI208-7 é adequado para 6 aplicaçãos: Industrial Control Glue Logic, Legacy Microprocessor Address Decoding, Multi-Rail Power Supply Sequencing, ASIC Emulation and Prototyping, Peripheral Expansion in Embedded Systems, Bus Arbitration and DMA Control.

🏭

Industrial Control Glue Logic

The EPM3512AQI208-7 is ideal for industrial glue-logic applications where deterministic timing and instant-on non-volatile configuration matter. Its 512 macro cells provide ample capacity for address decoding, peripheral chip-select generation, and interrupt aggregation in PLC and motor-drive systems. The 116.3 MHz fCNT and ~7.5 ns tPD allow the CPLD to keep pace with 32-bit microcontrollers while the 3.3 V core and 5 V-tolerant I/O simplify interfacing to legacy industrial buses. Unlike an FPGA, the MAX 3000A configuration is retained without external boot memory, which is critical for factory automation systems that must boot deterministically after power-on. The PQFP-208 package also supports socketed prototyping for in-field reconfiguration of legacy controllers.

🔧

Legacy Microprocessor Address Decoding

The EPM3512AQI208-7 excels at address decoding and bus interfacing for legacy 8/16/32-bit microprocessors such as 8051, 68k, and x86 embedded systems. With 512 macro cells, designers can implement full address decoding for memory-mapped peripherals, chip-select generation, and wait-state insertion in a single device, eliminating 6-10 discrete TTL/CMOS packages. The PQFP-208 footprint provides enough user I/O (typically 164+ signals) to support 24-bit address buses plus chip-select outputs. Compared with discrete 74LS/74HC logic, the CPLD reduces board area and improves signal integrity by centralizing decode logic on a single device with controlled output slew rates. Industrial temperature grade (-40C to +85C) suits outdoor and factory-floor equipment.

⚡

Multi-Rail Power Supply Sequencing

The EPM3512AQI208-7 is widely used for power-supply sequencing in multi-rail systems where processors, FPGAs, or ASICs require specific rail-on and rail-off ordering. Its 3.3 V core plus 5 V-tolerant I/O let the CPLD monitor upstream power-good signals and gate downstream regulators via ENABLE or PGOOD pins. With 116.3 MHz performance, the CPLD responds to fault conditions within microseconds - faster than discrete RC timing networks. The 512 macro cells accommodate sequencing logic for 6-12 rails, while the non-volatile configuration means sequencing behavior is correct on the very first power-on cycle, before any firmware loads. This is essential for ASICs and microprocessors that latch-up if rails are applied in the wrong order.

💡

ASIC Emulation and Prototyping

The EPM3512AQI208-7 serves as a prototyping vehicle for ASIC emulation, especially for designs originally targeting MAX 3000A silicon. Engineers can validate state machines, bus interfaces, and glue logic before committing to mask charges. With 10,000 usable gates and 512 macro cells, it accommodates medium-complexity ASIC functions and provides real-world timing validation. The PQFP-208 package can be socketed on a test board, allowing rapid iteration as the design is refined. The non-volatile EPROM-based configuration means the prototype works without boot memory - a major advantage over SRAM-based FPGAs that need a configuration PROM. The IEEE Std. 1532 ISP interface lets engineers re-program the device in seconds via JTAG.

📱

Peripheral Expansion in Embedded Systems

The EPM3512AQI208-7 is well suited to expanding I/O and peripheral count in microcontroller-based embedded systems. It can implement UARTs, SPI masters, I2C controllers, PWM generators, and custom parallel interfaces without consuming the microcontroller's firmware cycles. With 512 macro cells and 116.3 MHz performance, the CPLD handles multiple peripheral functions simultaneously, offloading real-time tasks from the MCU. The 5 V-tolerant I/O is invaluable when interfacing to legacy industrial peripherals that still use 5 V signaling. Engineers frequently use the device to add SD card controllers, LCD interfaces, or quadrature decoders to low-pin-count microcontrollers like the 8051 or PIC families.

🖥️

Bus Arbitration and DMA Control

The EPM3512AQI208-7 is commonly deployed for bus arbitration and DMA control in multi-master systems, where two or more bus masters (CPU, DMA controller, secondary processor) compete for shared memory or peripheral access. Its deterministic ~7.5 ns tPD provides predictable arbitration latency - critical for real-time systems where bus contention must be resolved in a known number of cycles. The 512 macro cells can implement multi-level priority encoders, bus-bridge logic, and timing-state machines in a single device. The 5 V-tolerant I/O bridges between 3.3 V cores and 5 V legacy peripherals, while the PQFP-208 footprint offers enough I/O for 32-bit data buses plus control signals. The non-volatile configuration ensures correct bus behavior from power-on, before any software is loaded.

What is the EPM3512AQI208-7?
The EPM3512AQI208-7 is a member of the Altera MAX 3000A family of Complex Programmable Logic Devices (CPLDs). According to the manufacturer datasheet, it provides 10,000 usable gates, 512 macro cells, 116.3 MHz maximum operating frequency, and is housed in a 208-pin PQFP package with 3.3 V core operation. The -7 suffix denotes its speed grade within the MAX 3000A family.
How many logic gates and macro cells does the EPM3512AQI208-7 contain?
The EPM3512AQI208-7 contains 10,000 usable gates organized into 512 macro cells distributed across 16 Logic Array Blocks (LABs) of 32 macro cells each. According to the MAX 3000A family datasheet, the device combines EPROM-based configuration memory with a programmable interconnect matrix (PIA) to deliver deterministic, non-volatile logic operation suitable for glue-logic and bus-interface tasks.
What is the operating voltage of the EPM3512AQI208-7?
The EPM3512AQI208-7 operates from a 3.3 V core supply (VCCINT) and supports 2.5 V, 3.3 V, or 5.0 V I/O operation via separate VCCIO pins. According to the MAX 3000A datasheet, the dual-rail architecture allows the device to interface directly with 5 V legacy logic on its I/O pins while running a 3.3 V internal core. This is one of the defining features of the MAX 3000A family.
Is the EPM3512AQI208-7 still in production?
The MAX 3000A family, including the EPM3512AQI208-7, is classified as NRND (Not Recommended for New Designs) by Altera/Intel.

As of 2026-09-12, distributor stock is limited because the part is NRND. For long-term supply, designers should evaluate MAX II or MAX V CPLDs as forward-compatible replacements.
What is the price of EPM3512AQI208-7?
As of 2026-09-12, the EPM3512AQI208-7 unit price is approximately $18.50 at qty 1, decreasing to about $9.85 at qty 1000, based on distributor listings aggregated on Octopart. Pricing reflects NRND/EOL market dynamics where remaining stock is being sold at premium prices. For new designs, MAX II CPLDs offer significantly lower pricing and active lifecycle status.
What is the lead time for EPM3512AQI208-7?
As of 2026-09-12, lead time for EPM3512AQI208-7 varies from immediate shipment (for in-stock distributor inventory) to 8-12 weeks for parts sourced through brokers or remaining factory inventory. Because the MAX 3000A family is NRND, lead times are expected to lengthen as remaining stock depletes. Designers should plan for migration to MAX II / MAX V families for long-term production.
EPM3512AQI208-7 vs EPM3512AQI208-10N - which is faster?
The EPM3512AQI208-7 is faster than the EPM3512AQI208-10N. The -7 speed grade delivers approximately 116.3 MHz toggle frequency with ~7.5 ns pin-to-pin delay, while the -10 grade operates around 92 MHz with ~10 ns delay. Both share the same 208-pin PQFP footprint and 512 macro cells, so the -7 is a drop-in upgrade for any -10 design.
Can EPM3512AQC208-7 replace EPM3512AQI208-7?
Yes, the EPM3512AQC208-7 can directly replace the EPM3512AQI208-7 on the same 208-pin PQFP footprint with identical 512 macro cells and 116.3 MHz performance. The only difference is operating temperature range: the 'C' suffix is commercial (0C to +70C), while the 'I' suffix is industrial (-40C to +85C). Use the I-suffix part for industrial-temperature applications.
When should I choose EPM3512AQI208-7 over MAX II CPLDs?
Choose the EPM3512AQI208-7 when you have an existing MAX 3000A design that needs to be re-spun without PCB changes, or when you need a non-volatile, instant-on CPLD in a socket-friendly PQFP-208 package that supports hand-soldering and rework. For new designs, prefer MAX II (EPM240) or MAX V CPLDs, which are active in production, lower cost, and available in finer-pitch packages.
Is the EPM3512AQI208-7 compliant with IEEE 1532?
Yes, the EPM3512AQI208-7 ISP (In-System Programming) circuitry is fully compliant with the IEEE Std. 1532 specification, according to the MAX 3000A family datasheet. IEEE Std. 1532 defines a standard ISP interface that enables concurrent programming of CPLDs from multiple PLD vendors using the same JTAG chain, simplifying manufacturing test and field upgrade.
What is the pinout of the EPM3512AQI208-7?
The EPM3512AQI208-7 is packaged in a 208-pin PQFP (Plastic Quad Flat Pack) with a 0.5 mm pin pitch. The complete pinout - including all user I/O, JTAG (TDI/TMS/TCK/TDO), VCCINT, VCCIO, and GND pins - is documented in the MAX 3000A family datasheet. Refer to the manufacturer pinout table for the exact pin assignment of every signal in the PQFP-208 package.

Guia de seleção

Choose EPM3512AQI208-7 when you need an industrial-temperature (-40C to +85C) MAX 3000A CPLD with the fastest -7 speed grade in the 208-pin PQFP package. It is the right choice for new industrial designs that need 116.3 MHz toggle performance and 5 V-tolerant I/O interfacing. Choose EPM3512AQC208-7 instead when your design operates only in commercial temperature range (0C to +70C) and you want the same speed at lower cost. Choose EPM3512AQI208-10N when you need a lower-cost option and can accept ~20% slower speed (~92 MHz). For new designs where the PQFP-208 footprint can be changed, evaluate MAX II (EPM240) or MAX V CPLDs in TQFP-100 or BGA packages, which are active in production and lower cost per macro cell.

Notas de projeto

The EPM3512AQI208-7 requires both a 3.3 V VCCINT rail and a separate VCCIO rail (which can be 2.5 V, 3.3 V, or 5.0 V). Place a 0.1 uF decoupling capacitor within 5 mm of every VCCINT and VCCIO pin, plus a single 10 uF bulk capacitor per rail. Power-up sequencing is not strictly required for the MAX 3000A, but holding JTAG TCK low during power ramp prevents accidental ISP. Estimated: ICCINT quiescent current is approximately 30-50 mA depending on logic utilization; design the 3.3 V regulator for at least 200 mA headroom.

The 208-pin PQFP package has a 0.5 mm lead pitch and gull-wing leads. For prototype boards use a PQFP-208 socket (e.g., 3M Textool or equivalent) to allow rapid device swaps. For production soldering, use a reflow profile with peak temperature 245-250C and ensure solder paste stencil aperture is 0.4 mm wide for proper fillet formation. Route high-speed outputs (clock, JTAG TCK) with 50 ohm controlled impedance and keep traces shorter than 50 mm to avoid ringing. Estimated: signal integrity margins degrade for traces above 50 mm at 116 MHz toggle rates.

Common pitfalls: (1) connecting VCCIO to the wrong voltage - the part is 5 V-tolerant on I/O when VCCIO = 3.3 V but NOT when VCCIO = 2.5 V. (2) Forgetting the JTAG pull-up resistor on TDI and TMS - these pins require 10 kohm pull-ups to VCCIO for reliable ISP. (3) Driving JTAG TCK faster than 10 MHz during ISP - the IEEE Std. 1532 interface limits TCK to 10 MHz for in-system programming. (4) Using the MAX 3000A in a new design without considering MAX II / MAX V migration - the family is NRND.

For designs that toggle multiple I/O pins simultaneously (e.g., address bus decoding on a 32-bit bus), enable the MAX 3000A's slow slew-rate option in Quartus to reduce ground bounce. Place series termination resistors (22-33 ohm) on outputs driving more than 50 mm of trace or more than 2 loads. The IEEE Std. 1532 JTAG chain must be terminated at the end-of-chain TDO pin with a 4.7 kohm pull-up to VCCIO. Estimated: ground bounce on 16 simultaneous switching outputs can reach 0.8 V without slew-rate control, which may corrupt logic on adjacent inputs.
