EPM3512AFI256-10 概述

The Intel (formerly Altera) EPM3512AFI256-10 is a 512-macrocell, 10,000-gate member of the MAX 3000A Complex Programmable Logic Device family, housed in a 256-ball FineLine BGA (FBGA-256) package and rated for the commercial 0C to 70C operating range. The device is implemented in 3.3-V CMOS EEPROM technology and delivers 4.5-ns pin-to-pin logic delays with internal counter frequencies up to 227.3 MHz, supported by 208 user I/O pins and a MultiVolt I/O interface that lets the 3.3-V core communicate with 5.0-V, 3.3-V, and 2.5-V logic environments without external level shifters.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocells with a central interconnect matrix, sitting in the programmable-logic hierarchy between small SPLDs (a few macrocells) and large SRAM-based FPGAs (tens of thousands to millions of LUTs). MAX 3000A parts in particular use EEPROM configuration cells so the bitstream is retained without external boot memory, which makes them attractive for glue-logic, bus-interface, and power-on sequencing roles where instant-on behavior matters.

Key features of the EPM3512AFI256-10 include 10K equivalent gates, 512 macrocells, IEEE Std. 1532-compliant 3.3-V in-system programmability (ISP) for concurrent vendor programming, MultiVolt I/O supporting 5.0/3.3/2.5-V interfaces, and 208 available user I/O pins routed through the 256-ball BGA. The ISP engine lets designers update logic in-circuit via JTAG, which simplifies field upgrades and reduces inventory SKUs.

Architecturally, the MAX 3000A family is built around Logic Array Blocks (LABs) of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and product-term steering. A single Joint Test Action Group (JTAG) interface handles both boundary-scan testing and ISP, and the 3.3-V core voltage simplifies power-tree design when the part is paired with 3.3-V MCUs or ASICs.

Typical applications include bus-interface bridging (e.g., glueless microprocessor-to-peripheral attachment), power-supply sequencing and supervisory logic, address decoding and chip-select generation, and high-speed state-machine controllers. Designers also use the EPM3512AFI256-10 for industrial control boards, telecom line-card glue logic, and legacy peripheral emulation where deterministic 4.5-ns propagation delay and non-volatile storage simplify board bring-up.

A key design consideration when using this part is that the FBGA-256 package requires X-ray or reflow-with-inspection assembly and a PCB with appropriate microvia stack-up; the 1.0 mm (or finer) ball pitch is not friendly to hand rework. Thermal performance is generally excellent because of the low CMOS quiescent current, but engineers should still budget for the 256-ball BGA's thermal resistance during worst-case continuous-toggle testing.

This page synthesizes distributor stock and pricing, MAX 3000A family drop-in alternatives, and practical glue-logic design notes not collected in the manufacturer datasheet, so procurement and design engineers can decide whether the EPM3512AFI256-10 is the right part for their next CPLD-based design.

EPM3512AFI256-10 适用于 6 应用s: Bus-Interface Bridging, Address Decoding and Chip-Select Generation, Power-Supply Sequencing and Supervisory Logic, Industrial Control and Factory Automation, Telecom Line-Card Glue Logic, Legacy Peripheral Emulation and Test Equipment.

🌐

Bus-Interface Bridging

The EPM3512AFI256-10 fits bus-interface bridging between microprocessors, ASICs, and legacy peripherals because it combines 208 user I/O pins, MultiVolt I/O (5.0/3.3/2.5 V), and 4.5-ns pin-to-pin logic delays in the same FBGA-256 package. The non-volatile EEPROM-based MAX 3000A architecture means the bridge logic is available at power-up with no boot PROM, so a 3.3-V host MCU can talk to a 5.0-V peripheral without glue logic. With 512 macrocells and 10K gates of capacity, the part can host both registered state machines for handshaking and combinatorial decoding for address or chip-select translation. Unlike SRAM-based FPGAs that require external configuration memory, the EPM3512AFI256-10 brings instant-on glue logic to asynchronous bus bridges between ISA, PCI, local-bus, and custom interfaces, with deterministic timing that survives cold-crank and brown-out events in industrial systems.

Address Decoding and Chip-Select Generation

Wide-address decoding and chip-select generation is a classic CPLD use case where the EPM3512AFI256-10 excels, with 512 macrocells handling large AND/OR product-term trees for 24- to 32-bit address spaces. The MultiVolt I/O interface lets the part decode 5.0-V memory buses while the core runs at 3.3 V, eliminating external level shifters on legacy microcontroller or DSP memory interfaces. Per the MAX 3000A data sheet, each macrocell can be configured as D, T, JK, or SR flip-flop with global clock networks, so registered chip enables are available with the same 4.5-ns tPD timing budget. Compared to discrete 74xx glue logic, the EPM3512AFI256-10 replaces multiple decoder and latch packages with a single 256-ball BGA, freeing board area while remaining in-system programmable through IEEE Std. 1532 JTAG for last-minute memory map changes.

Power-Supply Sequencing and Supervisory Logic

Power-supply sequencing controllers rely on the EPM3512AFI256-10 because the EEPROM-based MAX 3000A fabric powers up in a known state without external boot memory, and the 208 user I/O pins can drive dozens of enable and power-good signals across multi-rail systems. The part's deterministic 4.5-ns pin-to-pin logic delay lets designers build turn-on/turn-off sequencing chains with predictable timing across -40C to +70C (commercial) operation, while the MultiVolt I/O bank lets a 3.3-V CPLD talk to 5.0-V supervisor ICs and 2.5-V regulators. Each macrocell's programmable flip-flop and product-term allocation makes it straightforward to build watchdog timers, under-voltage lockout interlocks, and fault latches without external counters. For board areas where multiple rails (core, DDR, PLL, analog) must come up in strict order, the EPM3512AFI256-10 in FBGA-256 replaces a forest of 555 timers and discrete flip-flops with one JTAG-programmable part.

Industrial Control and Factory Automation

Industrial control boards in factory automation use the EPM3512AFI256-10 as deterministic glue logic that must survive harsh electrical environments, because the part's 3.3-V CMOS EEPROM architecture delivers known-state behavior at every power-on and the 208 I/O pins can interface directly to 5.0-V PLC backplanes or 24-V isolated digital inputs. MultiVolt I/O banks allow mixed-voltage signaling to motor-driver ICs, encoder counters, and HMI displays without external level translation, while the 4.5-ns tPD supports real-time deterministic response for safety interlocks. Designers also leverage the IEEE Std. 1532 ISP path to apply field updates when production lines reconfigure for new product variants, reducing inventory SKUs. Compared with SRAM FPGAs that need boot PROMs and configuration surveillance, the EPM3512AFI256-10 boots in microseconds with no external memory, making it well suited to machine controllers with short-cycle power cycles.

Telecom Line-Card Glue Logic

Telecom line cards in central offices and customer-premises equipment historically rely on the EPM3512AFI256-10 because it combines 512 macrocells, 10K gates, and 208 user I/O pins in a single 256-ball FBGA that fits between DSPs, framer ICs, and serializer/deserializer links. MultiVolt I/O bridges 5.0-V legacy TDM buses to 3.3-V or 2.5-V modern DSPs, and the 4.5-ns tPD plus 227.3-MHz internal counter frequency support E1/T1 and low-order Ethernet rate conversion. The non-volatile EEPROM fabric also means that line cards can boot into a known configuration without a configuration memory, which is valuable for unattended remote terminals. Across TDM-to-packet gateway designs, the EPM3512AFI256-10 implements framing, idle-pattern insertion, and clock-domain crossing without burdening the host processor.

Legacy Peripheral Emulation and Test Equipment

The EPM3512AFI256-10 is widely used for legacy peripheral emulation on ATE and test-and-measurement platforms because its 512 macrocells can recreate decades of bus protocols (ISA, VME, parallel ATA, SCSI) while the MultiVolt I/O banks match the original 5.0-V signaling levels. The 208 user I/O pins are sufficient to expose multiple emulation channels on one chip, and the 4.5-ns pin-to-pin delays match the timing of the legacy peripherals being replaced, so production test fixtures don't have to be re-qualified. IEEE Std. 1532 ISP allows field updates to support new device-under-test profiles, while the EEPROM-based configuration ensures that the emulation personality is preserved across power cycles. For laboratory instruments and JTAG-based production programmers, the EPM3512AFI256-10 in FBGA-256 packs the glue logic, personality PROM, and address decoder into a single programmable device.

What is the EPM3512AFI256-10?
The EPM3512AFI256-10 is a 512-macrocell, 10K-gate member of the Altera/Intel MAX 3000A Complex Programmable Logic Device (CPLD) family, supplied in a 256-ball FineLine BGA (FBGA-256) package. According to the MAX 3000A Family Data Sheet, it is built on 3.3-V CMOS EEPROM technology and provides 208 user I/O pins with MultiVolt I/O compatibility at 5.0 V, 3.3 V, and 2.5 V logic levels.
What is the maximum pin-to-pin propagation delay of the EPM3512AFI256-10?
The EPM3512AFI256-10 has a 4.5-ns pin-to-pin logic delay (tPD1) on the fastest paths and is rated for internal counter frequencies up to 227.3 MHz. A separate 7.5-ns propagation-delay figure also appears in third-party listings and is the conservative worst-case spec across I/O pin-to-pin combinations. Both numbers are taken from the MAX 3000A family data sheet, which covers speed grades -7, -10, and -12.
Can the EPM3512AFI256-10 be programmed in-system?
Yes. The EPM3512AFI256-10 supports 3.3-V in-system programmability (ISP) through its JTAG interface, and the MAX 3000A family ISP circuitry is compliant with IEEE Std. 1532, the standard for concurrent in-system programming across multiple PLD vendors. This lets designers update logic without removing the part from the board using a JTAG download cable and Altera/Intel Quartus programmer software.
What is the difference between EPM3512AFI256-10 and EPM3512AFI256-10N?
The EPM3512AFI256-10 and EPM3512AFI256-10N differ mainly in operating temperature grade: the -10 version is the commercial-grade (0C to +70C) part, while the -10N suffix on the MAX 3000A family denotes lead-free or RoHS-compliant packaging. Both share the same 256-ball FBGA, 512 macrocells, and 4.5-ns tPD, so they are functionally and pin-compatible for most designs.
Is there a drop-in replacement for EPM3512AFI256-10?
Yes. The closest drop-in replacements are other EPM3512AFC256-speed-grade variants on the MAX 3000A family (for example EPM3512AFC256-10, EPM3512AFC256-7N, and EPM3512AFC256-5C), all of which share the 256-ball FBGA footprint, 512 macrocells, and 208 user I/O pins but differ in speed grade or temperature grade. For logic-only swaps where timing differs slightly, the -7 and -5 speed grades are typically interchangeable.
What package does EPM3512AFI256-10 use?
The EPM3512AFI256-10 uses a 256-ball FineLine BGA (FBGA-256) with a 1.0 mm ball pitch. Per the MAX 3000A family data sheet, FBGA-256 is one of the largest packages offered in this family and supports the full 208 user I/O count. Designers should plan PCB microvia stack-ups and X-ray or post-reflow inspection since the fine-pitch BGA is not hand-rework friendly.
Where can I buy the EPM3512AFI256-10?
The EPM3512AFI256-10 can be purchased from authorized distributors including DigiKey (part number 544-1993-ND), Mouser, Octopart-listed brokers, Win Source, Veswin Electronics, and Jotrin. Stock and lead time vary by distributor because the MAX 3000A family has been in mature production for many years, so quote-based ordering is common. Price as of 2026-09-12 starts near $28.50 at qty 1 per Octopart aggregate.
What is the current price of EPM3512AFI256-10?
The unit price of the EPM3512AFI256-10 ranges from approximately $18.75 at qty 500 up to $28.50 at qty 1, based on Octopart distributor aggregation as of 2026-09-12. Pricing is sensitive to lead time, tape-and-reel vs. tray packaging, and RoHS/lead-free finish, so request formal quotes for production volumes above 100 pieces.
EPM3512AFI256-10 vs EPM7512AEFI256-10N - which should I choose?
Choose the EPM3512AFI256-10 if your design needs up to 512 macrocells and 10K gates in the MAX 3000A family, and choose the EPM7512AEFI256-10N if you need the larger MAX 7000AE-class part with 512 macrocells but a higher logic capacity and tighter timing. Both share the 256-ball FBGA footprint, but the MAX 7000AE family has different macrocell architecture, ISP voltage, and timing characteristics, so do not treat them as direct drop-in swaps.
How many user I/O pins does EPM3512AFI256-10 have?
The EPM3512AFI256-10 provides 208 user I/O pins out of its 256-ball FBGA package. According to the MAX 3000A family data sheet, the remaining balls are dedicated to VCCINT (core), VCCIO (I/O bank), GND, JTAG (TCK/TMS/TDO/TDI), and configuration pins, with the exact breakdown documented in the pin-out tables of the datasheet.
Is the EPM3512AFI256-10 still in production?
Yes. As of 2026-09-12, the EPM3512AFI256-10 remains listed as Active by Intel/Altera and by distributors such as DigiKey, Mouser, and Win Source. The MAX 3000A family is a long-running mature CPLD family that Intel has continued to support, although new designs are typically steered to MAX II, MAX V, or MAX 10 CPLDs for cost and power reasons.
What is the operating voltage of the EPM3512AFI256-10?
The EPM3512AFI256-10 core operates from a 3.3-V VCCINT supply, while its MultiVolt I/O banks can be independently powered at 5.0 V, 3.3 V, or 2.5 V to interface with mixed-voltage logic. Per the MAX 3000A family data sheet, decoupling must include 0.1 uF and 1 uF capacitors close to each VCC pin, and all VCC and GND balls must be connected for proper operation.
Where do I download the EPM3512AFI256-10 datasheet PDF?
The official MAX 3000A Family Data Sheet, which covers the EPM3512AFI256-10 along with all other MAX 3000A speed grades and packages, is available on Altera/Intel's website through the MAX 3000A product page. Third-party datasheet mirrors include Alldatasheet (46-page PDF), ADatasheet, and AlterSemi, but for the latest revision always cross-reference the Intel Altera Product Page.
Where is the EPM3512AFI256-10 pinout diagram located?
The full pinout table for the EPM3512AFI256-10's 256-ball FBGA package is in the MAX 3000A Family Data Sheet under the 'Pin Information' or 'FBGA-256 Package' section, which lists ball coordinates (A1 through N16), I/O bank assignments, and JTAG/test pin locations. Each pin's function, dedicated I/O bank VCCIO group, and any special configuration role are tabulated there.
Can I use the EPM3512AFI256-10 for bus-interface and glue-logic designs?
Yes. The EPM3512AFI256-10 is widely used for bus-interface bridging, address decoding, chip-select generation, and power-on sequencing because the MAX 3000A family provides non-volatile EEPROM configuration, deterministic 4.5-ns pin-to-pin delays, and 208 user I/O pins. For high-end glue logic combining multiple asynchronous buses, the 512 macrocells and 10K-gate capacity give you headroom for both combinatorial decoding and registered state machines.

选型指南

Choose the EPM3512AFI256-10 when your design needs the largest 512-macrocell, 208-I/O configuration of the MAX 3000A family at the standard 4.5-ns tPD speed grade, packaged in a 256-ball FineLine BGA, and you are running at commercial temperature (0C to +70C). It is the right part when 256 or 128 macrocell variants in the same family (such as EPM3256A or EPM3128A series) cannot hold the registered state-machine logic and combinatorial decoding you need. Pick EPM3512AFC256-7N instead if you have a timing-margin problem (faster tPD) or need a guaranteed lead-free finish. Pick EPM3512AFC256-5C only when you specifically need the fastest -5 speed grade. For new designs, also evaluate MAX II, MAX V, or MAX 10 CPLDs, which offer lower power and lower cost at similar logic density; however, those are different families with different pinouts and would require a fresh PCB layout.

关键差异点

  • Highest-density MAX 3000A part with 512 macrocells （对比 EPM3512AFC256-7N)
  • Largest FBGA package in the family (208 user I/O) （对比 EPM3512AFC256-5C)

设计说明

The FBGA-256 package on the EPM3512AFI256-10 uses a 1.0 mm ball pitch, which mandates a PCB with microvia stack-up (typically 4- to 6-layer with 0.4 mm laser-drilled vias) for reliable BGA breakout. Plan escape routing with via-in-pad or dog-bone fan-outs under the BGA, and avoid routing high-speed signals across the BGA's center row because internal balls are typically VCCINT/GND. Per MAX 3000A design guidelines, place 0.1 uF decoupling capacitors within 100 mils of every VCCINT and VCCIO ball, with one bulk 10 uF tantalum or ceramic per I/O bank.

Power up the EPM3512AFI256-10's 3.3-V VCCINT rail first or simultaneously with the I/O VCCIO rails; never apply VCCIO before VCCINT because the I/O buffers can back-power the core through ESD diodes, leading to latch-up. The MultiVolt I/O feature lets each I/O bank run at 3.3 V, 2.5 V, or 5.0 V-tolerant signaling, so if a 5.0-V bus is connected, set that bank's VCCIO to 3.3 V and rely on the 5.0-V-tolerant input stage; do not drive the bank's VCCIO to 5.0 V because the absolute maximum VCCIO is 3.6 V.

When programming the EPM3512AFI256-10 via JTAG, ensure that TCK is below 10 MHz on first-time board bring-up to avoid in-system programming failures, and pull TMS and TDI high through 10 kohm resistors to keep the TAP controller in a benign state. The MAX 3000A family ISP is IEEE Std. 1532-compliant, but you must still include a 1 kohm pull-up on TDO to define the JTAG bus idle level. Finally, do not leave unused I/O pins floating in production - configure them as outputs driving low or as inputs with internal pull-ups enabled in the Quartus pin-assignment file to reduce quiescent current and EMI.
