EPM7128SQC100-15 개요
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell arrays on a single die with a global interconnect fabric. The MAX 7000 family is Altera's second-generation EEPROM-based CPLD architecture, positioned between simple PLDs and FPGAs in the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. MAX 7000 parts retain configuration in on-chip EEPROM, so they boot instantly at power-up without an external configuration PROM - an advantage over SRAM-based FPGAs in deterministic-startup applications.
Key features of the EPM7128SQC100-15 include 128 macrocells organized into 4 Logic Array Blocks (LABs), a 2,500-gate typical density, 84 user I/O pins, programmable power management with macrocell-level slew-rate control, and a 15 ns tPD (worst-case pin-to-pin delay) suitable for 66 MHz operation. The device also provides 4 dedicated inputs, 6 to 10 product terms per macrocell, and a JTAG boundary-scan test interface compliant with IEEE 1149.1.
The architecture uses Altera's classic MAX (Multiple Array matriX) interconnect, with each LAB containing 16 macrocells feeding a Programmable Interconnect Array (PIA). This structure delivers fast, predictable combinational and registered logic delays that are independent of routing density - a key reason MAX 7000 CPLDs remain in long-life programs where deterministic timing matters more than raw density.
Typical applications include bus-interface glue logic, peripheral decoders and address mapping, state-machine control in industrial automation, board-level signal conditioning in telecom backplanes, and pin-compatible upgrades for legacy 5 V TTL/CMOS designs. The 5 V tolerance and PQFP-100 footprint also make it a common choice for maintenance of installed equipment in factory automation and aerospace ground systems.
When designing with this part, plan for an external 5 V regulator with at least 200 mA headroom and follow Altera's JTAG chain layout guidelines (TCK pull-down, TMS/TDI pull-ups) to avoid programming failures. Note that the EPM7128SQC100-15 is a mature / legacy product; verify lifecycle status before new designs.

일반적인 애플리케이션
EPM7128SQC100-15 적합 용도: 6 애플리케이션s: Bus Interface Glue Logic, Industrial Automation and Control, Telecom Backplane Signal Conditioning, Legacy Aerospace Ground Systems, Medical Device Control Logic, Test & Measurement Instrumentation.
Bus Interface Glue Logic
The EPM7128SQC100-15 is widely used as bus-interface glue logic between microprocessors, memories, and peripherals in legacy 5 V systems. Its 128 macrocells and 84 user I/Os provide ample capacity for address decoding, wait-state generation, and chip-select logic across 16/32-bit bus architectures. The 15 ns tPD introduces minimal address-to-CS latency, while the 5 V tolerance allows direct connection to TTL buses without level shifters. Compared to discrete 74-series glue, a single EPM7128SQC100-15 replaces 5 to 15 standard logic packages, simplifying PCB layout and improving reliability in industrial backplanes, VME/PCI bridges, and embedded computing platforms.
추천
Industrial Automation and Control
In industrial control systems, the EPM7128SQC100-15 handles deterministic state machines, sensor multiplexing, and motor-drive enable sequencing where predictable timing is paramount. The MAX 7000 architecture delivers fixed propagation delays that are independent of routing density - critical for safety interlocks and deterministic PLC scan cycles. Its 5 V I/O tolerates noisy 24 V-conditioned industrial signals via simple resistor dividers. The 128 macrocells support multiple parallel state machines for conveyor control, robotic arm sequencing, and packaging machinery, while JTAG boundary scan simplifies in-field board test during commissioning.
추천
Telecom Backplane Signal Conditioning
The EPM7128SQC100-15 serves telecom backplanes by providing clock distribution, frame synchronization, and line-interface signal conditioning at 5 V TTL levels. Its 84 user I/Os can fan out to multiple line cards while macrocell flip-flops re-time recovered clocks with sub-15 ns jitter. EEPROM-based configuration means the CPLD is ready at power-on without an external configuration PROM - essential for telecom systems that must boot deterministically after a power glitch. Long-life support and PQFP-100 footprint make it a stable choice for maintaining installed T1/E1, SDH, and legacy ATM switch line cards.
추천
Legacy Aerospace Ground Systems
Aerospace ground-test equipment and avionics maintenance rigs often retain 5 V TTL logic for backward compatibility with fielded avionics LRUs. The EPM7128SQC100-15 provides configurable stimulus generation, MIL-STD-1553 / ARINC 429 interface glue, and parallel-to-serial conversion in these long-life programs. Its PQFP-100 commercial-temperature package suits ground-bench environments, and the MAX 7000 architecture has decades of field reliability data. Designers should still apply derating per MIL-HDBK-1547 and verify up-to-date obsolescence status before long-term programs.
추천
Medical Device Control Logic
The EPM7128SQC100-15 is used in medical device control boards for deterministic sequencing of sensor acquisition, alarm logic, and front-panel I/O in 5 V systems. Its instant-on (EEPROM) configuration is critical for patient-safety devices that must boot reliably after power interruption without relying on external PROMs or firmware. The 15 ns tPD supports real-time control loops in infusion pumps, patient monitors, and diagnostic analyzers. Designers should perform ISO 14971 risk assessment, document firmware lifecycle plans, and verify supply continuity given the part's last-time-buy status.
추천
Test & Measurement Instrumentation
The EPM7128SQC100-15 functions as the timing-and-control brain in legacy test and measurement instruments such as logic analyzers, protocol testers, and bench-top data-acquisition systems. Its 84 user I/Os multiplex stimulus channels and capture trigger logic, while macrocell flip-flops synchronize high-speed comparators and ADC sequencers. Deterministic 15 ns timing supports repeatable test sequences required by compliance test rigs (USB, Ethernet, MIL-STD). JTAG boundary scan aids fixture-level board test, and the 5 V tolerance interfaces directly to legacy bench instrumentation signal levels.

설계 노트
The EPM7128SQC100-15 draws Icc in the range of approximately 100 to 300 mA depending on switching activity and output loading (per MAX 7000 datasheet power-estimation methodology). Estimated: at 5 V Vcc and 200 mA average, the part dissipates roughly 1 W; the PQFP-100 package has theta_JA around 35 C/W, producing a 35C junction rise above ambient at full activity. Provide a 5 V regulator with at least 400 mA capacity and a 1 uF decoupling cap on each Vcc pin pair (pins 65 and 100) placed within 5 mm of the package. Distribute GND (pins 11, 21, 31, 41, 51, 61, 72, 82, 91) across the PCB with a ground plane stitched directly under the device for thermal spreading.
PQFP-100 has a 0.65 mm lead pitch which is hand-solderable but not production-friendly. Use a stencil and reflow profile consistent with J-STD-020 (peak 235 C for SnPb or 245 C for lead-free). Keep all 9 GND pins connected to a single ground plane with multiple vias for low-impedance return paths. Place the JTAG chain header (TCK, TMS, TDI, TDO at pins 62-65 and 95) within 50 mm of the CPLD for reliable programming. If the design also uses an Altera configuration device, daisy-chain the JTAG signals so all devices are in one chain.
With 84 user I/Os at 5 V TTL levels, fan-out is generous (24 mA sink/source per pin on most macrocells), but parallel-bus designs should still use 33 ohm series damping resistors at outputs driving long traces (> 50 mm) to limit ringing. The 15 ns tPD means setup-time margins at clock frequencies above 33 MHz require careful tCO/tSU analysis - prefer the EPM7128SQC100-10 (10 ns) for designs above 40 MHz. Place a global clock input (pin 92 GCLK) where it sees the cleanest clock source and keep its trace length-matched with adjacent I/O to minimize skew across LAB boundaries.
Last-time-buy (LTB) status means factory stock is depleted and authorized distributors may show 0 inventory. Do not start new designs with this part without a qualified second source or design-life inventory purchase. The MAX 7000S toolchain is legacy MAX+PLUS II - if migrating to MAX 7000E (EPM7128EQC100-15), recompile in MAX+PLUS II as the libraries differ slightly. Verify all VCCINT and GND pin pairs are connected; missing a GND pin can cause erratic JTAG programming failures even though the device appears to function. Always pull TCK low through a 1 kohm resistor and TMS/TDI high through 10 kohm resistors when the JTAG header is unconnected, to prevent spurious JTAG state transitions during board reset.
규정 준수 정보
Standard EPM7128SQC100-15 uses SnPb lead finish and is NOT RoHS compliant. Use the EPM7128SQC100-15N (lead-free) variant for RoHS-compliant builds. Commercial temperature grade (0C to +70C); industrial and military grades are not offered in this part number. Last-time-buy status means future supply is from remaining inventory only.
