EPM3512AQC208-7 Tóm tắt

The Intel (formerly Altera) EPM3512AQC208-7 is a member of the MAX 3000A family of high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs) featuring 512 macrocells, 10,000 usable gates, and a 7.5 ns pin-to-pin propagation delay. Housed in a 208-pin Plastic Quad Flat Pack (PQFP) package, it provides 172 user I/O pins and operates at a 3.3 V core supply with MultiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V logic levels for mixed-voltage system interfacing. Counter frequencies reach up to 116.3 MHz, enabling fast state-machine and datapath implementation.

A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip, providing predictable timing, instant-on behavior, and high I/O count for glue-logic, bus-interface, and state-controller applications. CPLDs sit alongside FPGAs in the programmable logic hierarchy: FPGAs offer higher logic density and register count, while CPLDs excel at deterministic timing, lower power, and instant boot from on-chip EEPROM. The MAX 3000A family targets cost-sensitive industrial, communication, and consumer designs that need fast, deterministic logic integration.

The EPM3512AQC208-7 integrates in-system programmability (ISP) compliant with the IEEE Std. 1532 specification, allowing concurrent ISP across multiple PLD vendors and reconfiguration without removing the device from the board. The MultiVolt I/O pins interface directly with 5.0 V, 3.3 V, and 2.5 V logic, eliminating external level shifters when bridging legacy and modern buses. Built on a 0.30 um CMOS EEPROM process with a MAX architecture, the device delivers high logic density with predictable interconnect delays that are independent of routing patterns, simplifying static-timing closure.

Typical applications include bus-interface bridging, address decoding and glue logic for microprocessor systems, state-machine controllers, I/O expansion, and power-up sequencing for FPGAs or processors requiring controlled reset behavior. Designers often pair the EPM3512AQC208-7 with an external configuration PROM or use it standalone for deterministic control logic. Its instant-on EEPROM architecture boots the configured logic within microseconds, which is critical for safety-critical and deterministic system bring-up.

When designing with the EPM3512AQC208-7, observe the 208-PQFP thermal envelope and provide a sufficient ground/power plane on inner PCB layers to keep junction temperature below 125 C. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 100 mils of the pin, and use the Quartus II or MAX+PLUS II software toolchain for fitting, simulation, and JTAG-based ISP.

Ứng dụng tiêu biểu

EPM3512AQC208-7 phù hợp cho 6 Áp dụngs: Microprocessor Bus Interface Bridging, FPGA Configuration and Power Sequencing Controller, State Machine and Control Logic, Address Decoding and Memory Interfacing, I/O Expansion and GPIO Multiplexing, Legacy System Maintenance and Drop-In Replacement.

🌐

Microprocessor Bus Interface Bridging

The EPM3512AQC208-7's 172 user I/Os and 7.5 ns tPD make it an ideal bridge between microprocessors, DSPs, and peripherals operating at different bus widths or voltages. Its MultiVolt I/O directly interfaces 5.0 V legacy peripherals with 3.3 V modern cores without external level shifters, reducing BOM cost and board area. With 512 macrocells and deterministic timing, it can decode full 24-bit address spaces in a single pass, providing chip-select generation, wait-state insertion, and interrupt prioritization for systems requiring fast, predictable glue logic.

🖥️

FPGA Configuration and Power Sequencing Controller

FPGAs require strict multi-rail power-up and reset sequencing to prevent inrush damage and configuration errors. The EPM3512AQC208-7's instant-on EEPROM architecture boots in microseconds - far faster than FPGAs that need external configuration time - allowing it to drive enable lines, monitor PGOOD flags, and release FPGA reset only after all rails stabilize. Its 172 I/Os can manage multiple FPGAs, voltage regulators, and monitoring rails simultaneously, while the deterministic 7.5 ns tPD guarantees precise timing margins for sequenced power systems in industrial and telecom hardware.

🏭

State Machine and Control Logic

Industrial controllers, motor drives, and instrumentation require deterministic state machines with guaranteed response times. The EPM3512AQC208-7's CPLD architecture provides predictable, routing-independent 7.5 ns pin-to-pin delays that simplify static-timing analysis - unlike FPGAs whose interconnect delays vary with placement. With 512 macrocells and 116.3 MHz counter frequency, designers can implement multi-state FSMs, PWM generators, quadrature decoders, and protocol controllers in a single device, while the instant-on EEPROM eliminates boot-time variability in safety-critical control loops.

💡

Address Decoding and Memory Interfacing

Memory subsystems require precise address decoding with sub-nanosecond setup times to avoid bus contention. The EPM3512AQC208-7's 7.5 ns tPD and 172 I/Os support full 32-bit address decoding with multiple chip-select outputs that enable memory banks, ROMs, and peripherals in a single cycle. Its MultiVolt I/O interfaces directly with SRAM, DRAM, and Flash memories operating at 5 V or 3.3 V without glue logic. The deterministic timing makes it a preferred choice for legacy CPU boards and 8/16/32-bit embedded systems requiring reliable address decoding.

🧩

I/O Expansion and GPIO Multiplexing

Embedded systems frequently need more I/Os than the host microcontroller provides. The EPM3512AQC208-7 with 172 user I/Os can multiplex keypad rows/columns, LCD segment drivers, LED displays, and parallel peripherals through a serial SPI or I2C interface from the host. Its 3.3 V core with 5 V-tolerant I/O directly drives both modern and legacy peripherals, while the in-system programmability via JTAG allows field firmware updates without desoldering. This makes it ideal for industrial HMIs, point-of-sale terminals, and instrumentation front panels.

✈️

Legacy System Maintenance and Drop-In Replacement

Many industrial, military, and aerospace systems designed in the late 1990s and early 2000s use the EPM3512AQC208-7 and now face EOL pressure on legacy components. The same -7 part with original Altera die remains available through distribution channels, providing an authentic drop-in replacement that preserves qualification, certification, and form-fit-function. Designers can also substitute speed-grade variants (-10, -3) within the same 208-PQFP package if stock of the -7 grade is constrained. This makes the EPM3512AQC208-7 family an essential part for sustaining legacy equipment.

The EPM3512AQC208-7 contains 512 macrocells and 172 user I/O pins in a 208-pin PQFP package. With approximately 10,000 usable gates, it targets mid-density glue-logic designs. Compared to the EPM3256AQC208-7 (256 macrocells) and EPM3128ATC144-7 (128 macrocells), the 3512 is the highest-density 208-pin option in the family.
What is the difference between EPM3512AQC208-7 and EPM3512AQC208-7N?
The EPM3512AQC208-7 and EPM3512AQC208-7N share the same die, 208-PQFP package, and 7.5 ns speed grade. The '-N' suffix denotes a lead-free / Pb-free terminal finish compliant with RoHS. Per FindIC comparison data, both parts are pin-compatible drop-in equivalents. Choose the '-N' variant for new designs requiring RoHS compliance.
Where can I buy the EPM3512AQC208-7 and what is the price?
As of 2026-09-12, the EPM3512AQC208-7 is available from authorized distributors including DigiKey (part 544-1176-ND), Heisener, Veswin Electronics, Nantian, and Micro-Semiconductor. Heisener lists the qty-1 unit price at approximately $69.53, with bulk discounts reducing the price to roughly $41.72 at 1,000 pieces. Stock levels vary; lead time is typically 4-6 weeks from franchised distributors.
Is the EPM3512AQC208-7 still in production or is it obsolete?
The EPM3512AQC208-7 is classified as Not Recommended for New Designs (NRND) by Intel (formerly Altera). The MAX 3000A family has been superseded by MAX II, MAX V, and MAX 10 CPLD families. Existing designs continue to be supported, and distributor stock remains available, but new designs should target MAX II Z or MAX 10 devices for long-term supply continuity.
What is the difference between EPM3512AQC208-7 and EPM3256AQC208-7?
The EPM3512AQC208-7 (512 macrocells, 7.5 ns, 172 I/O) has double the macrocell count of the EPM3256AQC208-7 (256 macrocells, 7.5 ns, 164 I/O). Both share the 208-pin PQFP package and 3.3 V core, so the 3512 is a drop-in upgrade for designs that need more logic density. The 3256 is preferable when lower cost and lower power are sufficient for the design.
Can the EPM3512AQC208-7 be replaced by an EPM3512AFI256-7?
No, the EPM3512AFI256-7 uses a different package (256-pin FBGA) than the EPM3512AQC208-7 (208-pin PQFP). Although both share the same 3512 die and -7 speed grade, the I/O pinout and ball map differ. A direct drop-in PCB replacement is not possible; a board redesign with a new footprint is required. For a true drop-in within the PQFP-208 footprint, use the EPM3512AQC208-7N.
What is the best drop-in replacement for the EPM3512AQC208-7?
The EPM3512AQC208-7N is the best drop-in replacement for the EPM3512AQC208-7. Both share identical silicon die, 208-pin PQFP package, 512 macrocells, 7.5 ns tPD, and 3.3 V core; the only difference is the '-N' lead-free terminal finish. For higher speed, the EPM3512AQC208-10 (10 ns) is a slower-speed drop-in; for lower density at the same package, the EPM3256AQC208-7 also drops in.
Where can I download the EPM3512AQC208-7 datasheet PDF?
The MAX 3000A datasheet covering the EPM3512AQC208-7 is available from multiple sources. AllDataSheet hosts a 46-page PDF (715 KB) at https://www.alldatasheet.com/datasheet-pdf/pdf/595586/ALTERA/EPM3512AQC208-7.html. Intel hosts the official MAX 3000A Family Data Sheet on its Altera legacy documentation portal. The datasheet includes the IEEE Std. 1532 ISP specification, MultiVolt I/O description, and AC/DC characteristics.
Where can I find the EPM3512AQC208-7 pinout?
The full 208-pin PQFP pinout for the EPM3512AQC208-7 is documented in the MAX 3000A family datasheet. The device assigns four I/O banks to support MultiVolt signaling, with dedicated JTAG pins (TCK, TMS, TDI, TDO), VCCINT, VCCIO, and GND. Designers can download the BSDL file and pinout tables from Intel's legacy MAX 3000A documentation portal to verify per-pin function assignments.
What are the supported I/O voltage standards for EPM3512AQC208-7?
The EPM3512AQC208-7 supports MultiVolt I/O, allowing each I/O bank to interface with 5.0 V, 3.3 V, or 2.5 V logic levels while the core runs at 3.3 V. According to the datasheet, the I/O pins are 5.0-V tolerant when VCCIO is set to 3.3 V, enabling direct connection to legacy 5 V peripherals. This eliminates external level shifters in mixed-voltage designs.
What software toolchain programs the EPM3512AQC208-7?
The EPM3512AQC208-7 is programmed using the Altera/Intel Quartus II design software (legacy versions support MAX 3000A) or the older MAX+PLUS II toolchain. The device supports JTAG-based in-system programming compliant with IEEE Std. 1532, allowing concurrent ISP across multiple PLD vendors. A ByteBlasterMV or USB-Blaster download cable connects the JTAG pins to the host PC for configuration.
What is the operating temperature range of EPM3512AQC208-7?
According to the MAX 3000A datasheet, the EPM3512AQC208-7 operates over a commercial temperature range of 0 C to +70 C. Industrial-grade parts (suffix 'I') cover -40 C to +85 C. The junction-to-ambient thermal resistance for the 208-PQFP is approximately 35 C/W with proper PCB thermal vias. Designers should derate output drive at temperatures above 70 C.
What is the difference between EPM3512AQC208-7 and EPM3512AQC208-10?
The EPM3512AQC208-7 has a 7.5 ns tPD (116.3 MHz counter frequency), while the EPM3512AQC208-10 has a 10 ns tPD (100 MHz counter frequency). Both share the same 208-PQFP package, 512 macrocells, 3.3 V core, and MultiVolt I/O. The -7 is the faster speed grade; both are drop-in compatible, allowing designers to substitute the -10 if -7 inventory is constrained.
Is there a Lattice or Xilinx equivalent to the EPM3512AQC208-7?
Direct cross-vendor drop-in equivalents for the EPM3512AQC208-7 are limited because the MAX 3000A family uses Altera-proprietary architecture and pinout. Closest parametric competitors are Lattice ispMACH 4000 series (e.g., LC4256C, LC4512C) and Xilinx XC9500XL family (e.g., XC95144XL, XC95288XL). However, these require PCB redesign because package and pinout differ - no true drop-in cross-vendor replacement exists for the 208-PQFP footprint.

Dữ liệu tham khảo kỹ thuật cho EPM3512AQC208-7 — so sánh, hướng dẫn thiết kế và thông tin tuân thủ.

Hướng dẫn chọn lựa

Choose the EPM3512AQC208-7 when your design requires up to 512 macrocells of deterministic logic with 7.5 ns pin-to-pin delay in a 208-PQFP through-hole-friendly footprint. It is the highest-density option in the 208-pin PQFP MAX 3000A family, suitable for bus-interface bridges, address decoders, and power-sequencing controllers in industrial and telecom equipment. If your design requires RoHS compliance, choose the EPM3512AQC208-7N (identical silicon, lead-free finish). For slower timing budgets where 10 ns or 15 ns tPD is acceptable, choose the -10 or -15 grade for better availability and lower cost. For higher speed, use the -3 or -2 grade. If your logic density is below 256 macrocells, the EPM3256AQC208-7 is a more economical drop-in. For new designs, consider migrating to the MAX II Z (EPM240Z) or MAX 10 (10M02) families for active product longevity, but the MAX 3000A remains the right choice for sustaining legacy and certified systems.

Ghi chú thiết kế

Estimated: The EPM3512AQC208-7 draws approximately 100-300 mA at 3.3 V VCCINT depending on activity factor, plus I/O bank current at VCCIO. Decouple every VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 100 mils of the pin; add a bulk 10 uF tantalum or ceramic near the device. Place VCCIO decoupling per bank because each bank can run at a different MultiVolt level. Use separate analog and digital ground planes joined at a single point under the CPLD.

The 208-PQFP has a theta_JA of approximately 35 C/W. At maximum commercial ambient (70 C) and typical 1 W dissipation, junction temperature rises 35 C to about 105 C - within the 125 C limit but with limited headroom. Provide thermal vias under the exposed die pad (PQFP has no exposed pad; rely on copper pour and inner-layer ground planes for heat spreading). Avoid placing the CPLD near high-power devices; in enclosed industrial housings, derate to 60 C ambient.

Route JTAG signals (TCK, TMS, TDI, TDO) with 4-8 mil traces and keep them under 2 inches; place a 10 kohm pull-up on TCK, TMS, TDI per IEEE 1532. The 208-PQFP has fine-pitch gull-wing leads at 0.5 mm pitch - use 4-layer PCB with 4-mil space/4-mil trace design rules for escape routing. Keep high-speed output traces short and series-terminate if driving more than 2 inches.

Do not confuse the 208-PQFP with the 256-FBGA (EPM3512AFI256-7) - they are NOT drop-in compatible despite sharing the 3512 die. The PQFP uses peripheral gull-wing leads while the FBGA uses a ball grid; pin functions and I/O bank assignments differ. Also, the EPM3512AQC208-7 vs EPM3512AQC208-7N differs only in lead finish (Pb vs Pb-free) - both are electrically identical. Use Quartus II 13.0 or earlier for design compilation; newer Quartus versions dropped MAX 3000A support.

When interfacing 5 V peripherals with the EPM3512AQC208-7, set the relevant VCCIO bank to 3.3 V (not 5 V) - the I/O pins are 5 V tolerant when VCCIO = 3.3 V per MultiVolt spec. Driving 5 V signals into a VCCIO=2.5 V bank exceeds absolute maximum ratings. For clock inputs, keep rise/fall times below 200 ns and avoid ringing by source-terminating fast edges with a 33 ohm series resistor at the driver.
