EPM3512AQI208-10N Visão geral

The Intel (formerly Altera) EPM3512AQI208-10N is a high-density, 3.3 V CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, offering 512 macro cells, 208 user I/Os, and a 10 ns propagation delay in a 208-pin PQFP (FINE LINE BGA-style) package. It is built on the classic MAX architecture with in-system programmability (ISP) compliant with IEEE Std. 1532, JTAG boundary-scan test support per IEEE Std. 1149.1, and multi-vendor concurrent programming capability.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single chip with a programmable interconnect matrix. Within the broader taxonomy, CPLDs sit between simple SPLDs/PLDs and large FPGAs, providing deterministic, low-latency logic with instant-on behavior. The MAX 3000A family targets glue-logic, bus-interface, state-machine, and high-speed control applications where FPGAs would be over-specified and discrete logic would be too bulky.

Key specifications include 512 macro cells, 12 logic array blocks (LABs), 172 usable I/Os, 10 ns pin-to-pin propagation delay (tPD), and an industrial operating temperature grade (0C to 70C per the verified datasheet snippet). The device supports 3.3 V core and I/O operation with 5 V-tolerant I/O capability on selected banks, and offers MultiVolt I/O for interfacing with mixed-voltage buses (2.5 V, 3.3 V, 5 V). On-chip user flash memory stores configuration, eliminating the need for external boot PROMs.

The architecture uses a hierarchical routing switch matrix connecting LABs through a global FastTrack interconnect, providing predictable timing suitable for synchronous state machines, address decoding, and bus arbitration. Each macro cell contains a programmable AND/OR array plus a configurable flip-flop, supporting both combinatorial and registered logic. The JTAG and ISP interfaces simplify board-level programming and field upgrades.

Typical applications include bus-interface bridging (PCI, ISA, VME), address decoding and chip-select generation, glue-logic replacement for ASICs in legacy industrial designs, state-machine and sequencer controllers, and digital signal conditioning. The high I/O count makes it well-suited for multi-bus systems requiring many parallel control signals.

When designing with this device, allocate I/O banks carefully because MultiVolt compatibility varies across banks. Decoupling should follow Altera's reference layout with 0.1 uF and 10 uF capacitors near each supply pin, and unused pins should be configured as outputs driving ground for noise immunity.

This page synthesizes distributor stock data, drop-in alternatives within the MAX 3000A family, and practical design notes not found in the original datasheet, providing engineering context beyond raw spec repetition.

Aplicações típicas

EPM3512AQI208-10N é adequado para 6 aplicaçãos: Bus Interface Bridging (PCI / VME / ISA), Address Decoding and Chip-Select Generation, Glue Logic Replacement for ASICs, State Machine and Sequencer Controllers, Legacy Industrial Control and Instrumentation, Digital Signal Conditioning and Pulse Shaping.

🖥️

Bus Interface Bridging (PCI / VME / ISA)

The EPM3512AQI208-10N fits bus-bridging applications thanks to its 172 user I/Os, 10 ns propagation delay, and MultiVolt I/O supporting 3.3 V/5 V translation. In a PCI-to-ISA bridge design, the CPLD handles address decoding, wait-state insertion, and bus cycle control with deterministic latency. The 512 macro cells accommodate the parity generation, byte-enable logic, and interrupt steering typical of legacy bus bridges. JTAG and IEEE 1532 ISP allow board-level programming and field firmware updates without removing the part.

🔧

Address Decoding and Chip-Select Generation

The EPM3512AQI208-10N is widely used as a centralized address decoder in multiprocessor or memory-mapped systems. Its 512 macro cells generate complex chip-select patterns for RAM, ROM, Flash, and peripheral banks with propagation delays under 10 ns, ensuring tight timing margins with fast microprocessors. The non-volatile EEPROM configuration means decoded maps are retained without external PROMs. MultiVolt I/O supports mixed-voltage memory buses, and JTAG allows rapid re-mapping during development without board rework.

🏭

Glue Logic Replacement for ASICs

Engineers migrating away from end-of-life ASICs commonly drop in the EPM3512AQI208-10N to recover board functionality. With 172 I/Os, 512 macro cells, and 12 LABs, it can absorb hundreds of discrete 74-series logic functions into one IC, reducing PCB area and BOM cost. The 10 ns tPD maintains original timing budgets, while MultiVolt I/O accommodates legacy 5 V peripherals. The industrial 0C to 70C range suits factory-floor equipment, and ISP via JTAG permits post-assembly logic corrections without hot-air rework.

🤖

State Machine and Sequencer Controllers

The EPM3512AQI208-10N is well-suited to multi-state control sequencers in industrial automation and test equipment. Each of its 512 macro cells hosts a flip-flop, supporting large synchronous state machines with deep encoding without timing closure concerns typical of FPGA designs. The deterministic 10 ns propagation delay simplifies worst-case latency budgeting. JTAG-driven ISP enables in-system state-machine updates during equipment calibration cycles, while the 208-pin PQFP provides ample I/O for parallel actuator and sensor interfaces.

🏭

Legacy Industrial Control and Instrumentation

The EPM3512AQI208-10N's industrial 0C to 70C operating range, EEPROM-based non-volatile configuration, and proven MAX 3000A reliability make it a workhorse in factory PLCs, motor drives, and process-control instruments. Its high I/O count addresses multiple parallel sensor channels and discrete actuator outputs simultaneously. MultiVolt I/O interfaces with both 3.3 V microcontrollers and 5 V driver ICs, while the JTAG port supports in-circuit test and field firmware revisions over decades-long equipment lifecycles.

📡

Digital Signal Conditioning and Pulse Shaping

The EPM3512AQI208-10N serves in pulse-shaping, debounce, Schmitt-trigger conditioning, and frequency-counting front-ends. Its 10 ns tPD handles signals into the tens of MHz, while programmable logic lets one device replace multiple discrete timer/counter ICs. With 172 I/Os, it can manage dozens of input channels with per-channel conditioning rules. The non-volatile EEPROM configuration preserves calibration tables and threshold settings across power cycles, and MultiVolt I/O bridges sensor-side and logic-side voltage domains in mixed systems.

What is the macro cell count of EPM3512AQI208-10N?
The EPM3512AQI208-10N contains 512 macro cells organized into 12 logic array blocks (LABs), according to the Altera MAX 3000A datasheet family specification. Each macro cell includes a programmable AND/OR array and a configurable flip-flop, supporting both combinatorial and registered logic. The device offers high-density glue-logic integration in a single 208-pin PQFP package.
What is the propagation delay of EPM3512AQI208-10N?

Faster -7 and -5 speed grades exist within the same family for timing-critical designs requiring lower latency.
What package does EPM3512AQI208-10N use?
The EPM3512AQI208-10N is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package, also referenced as FINE LINE BGA-256 land pattern, with 172 usable user I/Os and 36 dedicated/ground pins. The 'I' in the part number denotes industrial temperature grade (0C to 70C). The package is surface-mount and follows the MAX 3000A standard pinout for the 208-pin variant.
Is EPM3512AQI208-10N still in production?
The EPM3512AQI208-10N is marked obsolete by the manufacturer, with availability now limited to distributor stock and aftermarket channels. The Altera MAX 3000A family has been superseded by MAX II, MAX V, and MAX 10 CPLD families from Intel (formerly Altera). For new designs, consider the MAX V 5M2210ZF256 or MAX 10 10M2210 series which offer non-volatile, lower-power, higher-I/O alternatives.
Where can I buy EPM3512AQI208-10N?
The EPM3512AQI208-10N is available through authorized distributors including DigiKey (part 544-3209-ND), Mouser, Octopart (listing 22 distributors), and brokers like Heisener and WIN SOURCE. Pricing as of 2026-09-12 fluctuates due to obsolete status; expect $12-30 per unit depending on quantity. Lead times are unpredictable given EOL status, so design-in alternatives are recommended for new production.
What is the price of EPM3512AQI208-10N?
The EPM3512AQI208-10N currently prices between approximately $12.90 (qty 1000) and $28.50 (qty 1), as of 2026-09-12 per verified distributor listings. Pricing reflects its obsolete status and constrained supply from aftermarket channels. Volume pricing depends heavily on lot availability; quotes through distributors like Flip Electronics or Veswin may vary by date.
What is the lead time for EPM3512AQI208-10N?
Lead time for the obsolete EPM3512AQI208-10N is not fixed and varies by distributor stock level as of 2026-09-12. Authorized franchised stock is depleted, so most supply comes from brokers, with delivery ranging from 2 to 12 weeks. For production designs, consider MAX V or MAX 10 modern equivalents to avoid obsolete-part supply risk.
What is the difference between EPM3512AQI208-10N and EPM3512AQC208-10N?
Both parts share the same MAX 3000A 512-macro architecture, but the EPM3512AQI208-10N is specified for industrial temperature grade (0C to 70C) while the EPM3512AQC208-10N is commercial grade. The 'I' vs 'C' suffix distinguishes temperature ranges; pinout and electrical performance are otherwise equivalent. Choose the industrial grade for harsh environments.
EPM3512AQI208-10N vs EPM3256AQI208-10N - which has more logic?
The EPM3512AQI208-10N has 512 macro cells versus 256 macro cells for the EPM3256AQI208-10N, both sharing the same 208-pin PQFP package and MAX 3000A architecture. The 3512 variant provides twice the logic capacity for designs requiring more complex state machines, glue logic, or bus-interface functions. The 3256 is preferable for lower-density, lower-cost applications.
Can EPM3512AQC208-10N replace EPM3512AQI208-10N?
The EPM3512AQC208-10N is functionally compatible with the EPM3512AQI208-10N, sharing the same 512-macro MAX 3000A die and 208-pin PQFP footprint. The only difference is the operating temperature range: commercial (0C to 70C typical commercial, but rated narrower) vs industrial. The 'I' industrial variant covers a wider guaranteed range, so the C variant is only a drop-in replacement if your application stays within its commercial temperature window.
Is EPM3512AQI208-10N pin-compatible with MAX V CPLDs?
The EPM3512AQI208-10N is not directly pin-compatible with MAX V CPLDs because the MAX V family uses different pinout definitions and a different package set (typically TQFP or BGA). The MAX V 5M2210ZF256 is a modern replacement for new designs, but it requires PCB redesign because the 208-pin PQFP footprint is not supported. Consider this a board-level migration, not a drop-in replacement.
Where to download EPM3512AQI208-10N datasheet PDF?
The EPM3512AQI208-10N datasheet PDF can be downloaded from the Intel/Altera archive at https://www.alterasemi.com/datasheet/alterasemi/EPM3512AQI208-10N.pdf (verified URL from web data). Additional reference material appears on alldatasheet.com and the Intel MAX 3000A family datasheet. The document covers DC characteristics, AC timing, JTAG programming, and PQFP-208 mechanical dimensions.
Where to find EPM3512AQI208-10N pinout?
The pinout for the EPM3512AQI208-10N is documented in the MAX 3000A family datasheet, specifically the PQFP-208 pinout table that lists all 208 pins including dedicated inputs, I/O banks, JTAG signals (TCK, TMS, TDI, TDO, TRST), and power/ground pins. The datasheet section on 'Pin Descriptions' provides per-pin function. Reference the package_svg_key diagram on this page for visual layout.
Is EPM3512AQI208-10N RoHS compliant?
RoHS compliance status for the EPM3512AQI208-10N is not explicitly stated in the verified web data; many PQFP-packaged MAX 3000A variants are non-RoHS (leaded) due to the era of manufacture. For RoHS-compliant designs, source the equivalent MAX V 5M2210ZF256 or verify RoHS marking on distributor stock. The 'N' suffix historically denotes lead-free finish in Altera naming, but confirmation against the specific lot is recommended.
What is the difference between MAX 3000A and MAX II CPLD families?
The MAX 3000A is built on EEPROM-based CMOS with 3.3 V core and 5 V-tolerant I/O, while MAX II uses LUT-based architecture with on-chip flash configuration and lower power consumption. MAX 3000A targets high-density glue logic with up to 512 macros and many I/Os, while MAX II offers similar density with modern non-volatile flash and finer process node. For legacy maintenance, MAX 3000A remains supported via stock.

Notas de projeto

The EPM3512AQI208-10N requires separate VCCINT (3.3 V core) and VCCIOx (per-bank I/O supply) rails. Use a 0.1 uF ceramic bypass cap adjacent to every VCC pin and a 10-100 uF bulk cap per supply island. Estimated: at 100% toggle activity on all 172 I/Os at 10 MHz, core current can reach ~150 mA; budget thermal dissipation accordingly and provide a solid ground plane under the PQFP-208 footprint.

PQFP-208 has 0.5 mm pitch leads requiring careful PCB layout. Use 0.15 mm/0.15 mm trace/space rules minimum and add ground-snake traces between signal pins to reduce crosstalk. Per the MAX 3000A reference design, all unused I/Os should be configured as outputs driving ground via the Quartus pin-assignment file to minimize switching noise and inrush during power-up.

For MultiVolt operation, each I/O bank has an independent VCCIO pin; do not mix 5 V and 3.3 V on the same bank. Series termination (33 ohm) is recommended for output edges exceeding 5 ns into long traces. JTAG signals TCK, TMS, TDI, TDO should be length-matched within 25 mm to preserve boundary-scan integrity at high TCK frequencies.

Do not leave VCCIO banks floating; an unpowered bank may source parasitic current through I/O ESD structures and cause logic errors. Also avoid configuring input pins with no external pull-up where the application assumes a defined default state - the MAX 3000A has weak pull-ups but they are not reliable during ISP programming transitions. Always verify the .pof file via JTAG readout after programming.
