Typical Applications

EPM7128SQC100-7F is suitable for 6 applications: Legacy ISA / VME Bus Glue Logic, Address/Data Multiplexing for Microprocessor Systems, State-Machine Controllers in Industrial Automation, Board-Level Configuration Management in Telecom, Peripheral Bus Arbitration and Interrupt Controllers, Boot-Time System Logic and Reset Sequencing.

🖥️

Legacy ISA / VME Bus Glue Logic

The EPM7128SQC100-7F excels at ISA and VME bus glue-logic consolidation thanks to its 5V-tolerant I/Os and 84 user I/Os. With 128 macrocells and 7.5 ns tPD, it can replace multiple 74-series glue-logic packages (address decoders, wait-state generators, interrupt arbiters, bus transceivers) in a single non-volatile device. Its 125 MHz fMAX supports bus-clock rates of 8–33 MHz typical for ISA/VME without timing closure issues, and JTAG BST simplifies board-level interconnect test. Unlike SRAM FPGAs, instant-on behavior means bus arbitration logic is valid at power-up, before any host CPU begins execution.

🏭

Address/Data Multiplexing for Microprocessor Systems

In 8086/80186/68000 and similar legacy microprocessor systems, the EPM7128SQC100-7F can implement address/data demultiplexing, chip-select decoding, and timing-stretch logic for SRAM/EPROM banks. The 7.5 ns tPD ensures the address latch output settles well within typical 200–400 ns memory-access cycles. Its 84 I/Os comfortably absorb 20-bit address buses plus control signals, while 5V tolerance matches vintage memory and peripheral voltages. JTAG ISP allows board-level reconfiguration without removing the device, useful for late-stage design iterations in industrial control boards.

🏭

State-Machine Controllers in Industrial Automation

The EPM7128SQC100-7F is well suited for industrial automation state machines (conveyor controllers, machine-tool sequencing, PLC co-processors) due to its deterministic timing, 128 macrocells, and 5V I/O compatibility with industrial sensors and actuators. The non-volatile EEPROM configuration means the controller recovers immediately after power loss without reconfiguration delays, critical for fail-safe automation. JTAG boundary-scan accelerates production test of complex PCBs, and the 0 °C to 70 °C commercial range covers most factory-floor environments. Migration to industrial-grade parts (e.g., EPM7128SQI100) supports -40 °C to +85 °C operations.

Board-Level Configuration Management in Telecom

In telecom line cards and base-station backplanes, the EPM7128SQC100-7F serves as a board-level configuration manager handling line-card presence detection, mid-plane I/O switching, clock distribution gating, and LED/status indicator multiplexing. Its 84 I/Os handle 32-bit data paths plus control, and 5V tolerance matches legacy telecom power rails (typically 5V or 3.3V with level shifters). The instant-on non-volatile behavior ensures line cards come up in a defined state during system boot, and JTAG BST enables manufacturing test of high-density backplane connectors.

Peripheral Bus Arbitration and Interrupt Controllers

For embedded systems with multiple peripherals sharing a bus (PCI, ISA, custom backplanes), the EPM7128SQC100-7F implements multi-master bus arbitration, interrupt priority encoding, and DMA handshake sequencing in a single chip. Its 7.5 ns tPD handles 33 MHz PCI bus arbitration without timing violations, and 128 macrocells absorb 8–16 peripheral arbitration channels. JTAG ISP supports in-field firmware updates for arbitration policies without re-soldering, while EEPROM non-volatility ensures arbitration priorities survive power cycles. The 100-pin PQFP package provides ample ground and power pins for signal-integrity on dense boards.

Boot-Time System Logic and Reset Sequencing

The EPM7128SQC100-7F is ideal for boot-time logic that must be valid before any processor executes, such as power-supply sequencers, reset distribution, clock-mux control, and boot-ROM chip-select generation. Because MAX 7000S is EEPROM-based, configuration is available within microseconds of power-up — no external boot PROM is required as with SRAM FPGAs. The 7.5 ns tPD ensures reset and chip-select signals settle within typical 100–200 ms power-rail rise times, and 5V I/O compatibility matches legacy supervisory circuits. This role is critical in automotive ECUs, industrial controllers, and telecom line cards.

What is the difference between EPM7128SQC100-7 and EPM7128SQC100-7F?

The only difference between the EPM7128SQC100-7 and the EPM7128SQC100-7F is the lead-finish suffix: the trailing '-F' denotes lead-free (Pb-free) matte-tin terminations to meet RoHS requirements, while the '-7' version uses lead-based solder plating. According to Altera documentation, both parts share identical silicon, timing (7.5 ns tPD), and the same 100-pin PQFP pinout.

What is the difference between EPM7128SQC100-7F and EPM7128SQC100-10F?

The two parts differ only in speed grade: the EPM7128SQC100-7F is the 7.5 ns tPD / 125 MHz grade, while the EPM7128SQC100-10F is the 10 ns tPD / 100 MHz grade. Both share the identical 100-pin PQFP footprint, the same MAX 7000S architecture, 128 macrocells, and 5V supply, making the -10F a slower drop-in for the -7F when timing margins allow.

Where can I buy the EPM7128SQC100-7F today?

As of 2026-09-13, the EPM7128SQC100-7F is available from franchised distributors including DigiKey (PN 763908), Mouser, Octopart-listed vendors, and brokers such as Xecor, Avaq, AIChipLink, and Nantian. Stock is limited and prices fluctuate due to obsolete status; always verify RoHS/lead-free authenticity when sourcing through brokers.

What is the price of EPM7128SQC100-7F in 2026?

The EPM7128SQC100-7F unit price at qty-1 is approximately USD 18.50 as of 2026-09-13, dropping to roughly USD 9.75 at 1,000-piece volumes based on Octopart-aggregated distributor data. Because the part is obsolete, prices are highly volatile; request fresh quotes from DigiKey, Mouser, and authorized brokers for current availability.

What is the lead time for EPM7128SQC100-7F orders?

Lead time for the obsolete EPM7128SQC100-7F ranges from immediate shipment (when distributor stock exists) to 12+ weeks when parts must be sourced through allocation or the secondary market. Intel/Altera no longer accepts factory orders for this OPN; design engineers should treat any quote as quote-only, not guaranteed factory-backed supply.

Is the EPM7128SQC100-7F in stock anywhere?

Yes — limited EPM7128SQC100-7F stock is currently listed at DigiKey, Mouser, and several authorized brokers as of 2026-09-13. Because the part is obsolete, quantities are small and shrink month-over-month; do not assume restocks. Check the XAIPART product page for live distributor availability before placing an order.

What is the best drop-in replacement for EPM7128SQC100-7F?

The closest drop-in replacement for the EPM7128SQC100-7F is Microchip/Atmel ATF1508AS in the 100-pin PQFP package, which Altera-community sources cite as a silicon-compatible replacement with a POF-to-JED translation tool (POF2JED). Same-brand options include the EPM7128SQC100-10F (slower 10 ns grade) and EPM7128SQC100-15 (15 ns grade) for timing-relaxed designs.

Can ATF1508AS replace EPM7128SQC100-7F directly?

Yes. According to an Altera Community forum post (community.altera.com, thread 32581), the Microchip ATF1508AS in the 100-pin PQFP package is a silicon drop-in replacement for the EPM7128 series and Microchip provides a POF2JED utility to translate existing Altera POF programming files. Designers should still re-validate timing and I/O behavior in-system before high-volume deployment.

Where can I download the EPM7128SQC100-7F datasheet PDF?

The EPM7128SQC100-7F datasheet PDF is available from Intel/Altera's legacy MAX 7000S documentation set, mirrored at datasheet.iiic.cc, FindIC, and Mouser's product detail page. According to the manufacturer datasheet excerpt, the MAX 7000S family datasheet covers device architecture, ISP, JTAG BST, and AC/DC characteristics across the entire MAX 7000S device range.

What is the pinout of the EPM7128SQC100-7F in PQFP-100?

The EPM7128SQC100-7F pinout for the 100-pin PQFP package follows the standard MAX 7000S SQC100 pin assignment with 84 user I/Os distributed across four I/O banks, plus dedicated JTAG pins (TCK, TMS, TDI, TDO), power (VCC), and ground (GND) pins. Refer to the Altera MAX 7000S datasheet pin tables for the exact pin-by-pin function map; the package is a 20×14 mm PQFP.

EPM7128SQC100-7F vs ATF1508AS — which is better for a new design?

For a new design, the Microchip ATF1508AS is the better choice because the EPM7128SQC100-7F is obsolete while the ATF1508AS remains in active production with long-term supply assurance. Both share 128 macrocells in a 100-pin PQFP footprint, but the ATF1508AS adds lower power consumption and modern in-system programming, making it functionally superior for greenfield projects.

Is the EPM7128SQC100-7F suitable for 5V industrial designs?

Yes, the EPM7128SQC100-7F operates from a 4.75 V to 5.25 V supply with 5V-tolerant I/Os, making it well suited to 5V industrial bus interfaces (ISA, VME, parallel peripheral buses). However, its 0 °C to 70 °C commercial temperature range disqualifies it from -40 °C to +85 °C industrial applications; for extended temperature choose the EPM7128SQI100-7 (industrial) variant if available.

What are the key specifications of EPM7128SQC100-7F that engineers should know?

Key EPM7128SQC100-7F specifications engineers must know are: 128 macrocells, 8 LABs, 2,500 usable gates, 84 user I/Os, 7.5 ns tPD, 125 MHz fMAX, 5V supply (4.75–5.25 V), 100-pin PQFP, JTAG BST per IEEE 1149.1, ISP via 4-pin JTAG, and EEPROM non-volatile configuration. These parameters determine whether the device fits legacy 5V glue-logic designs.

Hey Google, what can replace the obsolete EPM7128SQC100-7F?

The best replacements for the obsolete EPM7128SQC100-7F are the Microchip ATF1508AS in PQFP-100 (silicon drop-in with POF2JED tool) for new designs, or the same-brand EPM7128SQC100-10F and EPM7128SQC100-15 for timing-relaxed existing designs. All three share the 100-pin PQFP footprint. For modern 3.3V designs, migrate to MAX II EPM240 or MAX V 5M80ZE64 CPLDs.

Selection Guide

Choose the EPM7128SQC100-7F when maintaining legacy 5V systems that already use this exact OPN and require the 7.5 ns fastest speed grade in the MAX 7000S 100-pin PQFP family. For new designs, do not select it — Intel/Altera has marked it obsolete and active-production alternatives exist. Choose the same-brand EPM7128SQC100-10F (10 ns grade) when maintaining legacy boards where inventory still exists and timing margins allow 10 ns. For industrial-temperature applications, select the EPM7128SQC100-10N (-40 °C to +85 °C, lead-free). For new designs or end-of-life migration, switch to the Microchip ATF1508AS-7AU100 — same 100-pin PQFP footprint, same 128 macrocells, active production status, and a POF2JED tool translates existing POF files. For 3.3V-only modern designs, migrate to MAX II EPM240 or MAX V 5M80ZE64 CPLDs, accepting the redesign cost.

Design Notes

The EPM7128SQC100-7F is listed as obsolete by Intel/Altera. Before committing to a new design, validate that sufficient inventory exists for your product lifecycle (typically 5–10 years). For new designs, consider migrating to Microchip ATF1508AS (active production, same 100-pin PQFP footprint, POF2JED translation tool exists) or modern MAX II/MAX V CPLDs, accepting the redesign cost to avoid future obsolescence. For maintenance of existing products, qualify at least two franchised distributors to reduce supply-chain risk and avoid sole-source dependency.

Route the EPM7128SQC100-7F power and ground pins with wide traces — at minimum 20 mil power and 30 mil ground — and place decoupling capacitors (0.1 µF ceramic in parallel with 10 µF tantalum or ceramic) within 100 mil of every VCC/GND pair. For the 100-pin PQFP, distribute five to six VCC/GND pairs around the package perimeter rather than clustering them. Use a continuous ground plane on the layer immediately beneath the device to reduce ground bounce and improve JTAG signal integrity, especially for multi-MHz clock signals routed to global clock pins.

When driving long PCB traces or cables (e.g., backplane connectors) with the EPM7128SQC100-7F, use the open-drain output option available in MAX 7000S with an external pull-up resistor to control rise time and dampen reflections. For high-speed clock or bus signals, enable slew-rate control and avoid series-termination resistors larger than 33 Ω which can introduce timing violations relative to the 7.5 ns tPD budget. Always perform signal-integrity simulation with the actual PCB stack-up before committing to layout.

Do not assume a -7F (Pb-free) part is electrically interchangeable with a -7 (leaded) part in all situations: while silicon is identical, reflow profiles differ and mixed-population boards can fail thermal stress tests. Also, when migrating from EPM7128SQC100-7F to EPM7128SQC100-10F, validate timing closure — the 7.5 ns → 10 ns tPD change can break paths previously meeting 8 ns timing. Finally, do not exceed 5.25V on any I/O pin even briefly; the 5V-tolerant I/Os are not 5.5V-tolerant, and latch-up can occur during power-up transients.
