EPM7128SQC100-7F - MAX 7000S 128-Macrocell CPLD 7.5ns | Altera
MPN: EPM7128SQC100-7F ✗ پایان تولیدEPM7128SQC100-7F نمای کلی
A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable IC that implements combinational and sequential logic in a single chip. CPLDs sit hierarchically between simple PLDs and FPGAs: they offer predictable timing (fixed propagation delay), deterministic power-up behavior, and much higher logic density than 22V10-style GALs, but lower density than SRAM-based FPGAs. MAX 7000S belongs to the EEPROM-based CPLD class — the configuration is retained without external memory and the device is in-system programmable (ISP) via JTAG.
Key features of the EPM7128SQC100-7F include eight logic array blocks (LABs) of 16 macrocells each, a programmable interconnect array (PIA), per-macrocell flip-flops with clear/preset, and JTAG boundary-scan test (BST) circuitry compliant with IEEE 1149.1. The 'SQC100' package code denotes a surface-mount PQFP-100 at commercial 0 °C to 70 °C temperature range, while the '-7F' speed suffix specifies the 7.5 ns tPD grade with lead-free (Pb-free) matte-tin terminations.
The architecture uses 5V-tolerant I/O with multi-voltage support, open-drain output option, and a global clock network shared by all LABs. Each macrocell contains a product-term array of 5×32 = 160 gates feeding a programmable register, which can be bypassed for pure combinational logic. Compared to its MAX 7000E predecessor, the 'S' (suffix S) variant adds JTAG BST in 128-macrocell and larger devices, expanded ISP capability, and the open-drain output option for wired-OR/wired-AND buses.
Typical applications include legacy peripheral bus decoding (ISA, PCI, VME glue logic), address/data multiplexing between microprocessors and memories, state-machine controllers in industrial automation, and board-level configuration management in telecom and networking line cards. The instant-on behavior makes it well suited for boot-time logic that must be valid before any processor begins execution.
When designing with this part, note that the MAX 7000S series is mature and Intel/Altera has marked most OPNs as obsolete or last-time-buy; verify current lifecycle status before starting a new design. For new designs where lifecycle supply assurance matters, evaluate the MAX II or MAX V families as modern equivalents.

کاربردهای معمول
EPM7128SQC100-7F مناسب است برای 6 کاربردs: 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.
پیشنهادی
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.
پیشنهادی
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.
پیشنهادی
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.

یادداشتهای طراحی
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.
