EPM3512AQI208-10N Обзор

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.

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.

Руководство по выбору

Choose the EPM3512AQI208-10N when you need high-density (512 macro) CPLD logic in a PQFP-208 surface-mount package for industrial temperature applications such as bus-interface bridges, address decoders, and state-machine controllers. It is preferred over EPM3256AQI208-10N when 256 macros are insufficient, and preferred over EPM3512AQC208-10N when industrial 0C to 70C reliability is required. For new designs, consider migrating to MAX V (5M2210ZF256) or MAX 10 CPLDs to avoid obsolete-part supply risk. The PQFP-208 package is recommended for manufacturing-friendly assembly; choose EPM3512AFC256-10N only if PCB space is critical and BGA assembly is available. All MAX 3000A family parts share identical JTAG/ISP programming flows, easing migration within the family.

Заметки по проектированию

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.
