EPM7128STC100-7 Présentation

The Intel (formerly Altera) EPM7128STC100-7 is a 128-macrocell high-density CPLD from the MAX 7000S family, packaged in a 100-pin TQFP and operating from a 5V supply with 84 user I/Os. Based on Altera's second-generation MAX architecture, it provides approximately 2,500 usable gates and supports in-system programmability through a 4-pin JTAG interface. The part is rated for a 7.5 ns pin-to-pin propagation delay with a maximum internal frequency of 125 MHz (some sources list 250 MHz for internal performance), suiting glue-logic, bus-interface and state-machine designs that require fast deterministic response.

A Complex Programmable Logic Device (CPLD) is a non-volatile programmable IC that combines multiple PAL-like macrocell blocks on a single die with a programmable interconnect matrix. In the system hierarchy, the CPLD sits between discrete 74-series glue logic and an FPGA, offering deterministic timing, instant-on behavior from on-chip EEPROM, and typically 30-600 macrocells per device. Because the configuration is stored in non-volatile memory, MAX 7000S CPLDs boot in microseconds with no external boot PROM, making them ideal for power-on control, I/O expansion and bus bridging.

Key features of the EPM7128STC100-7 include 128 macrocells distributed across 8 logic array blocks (LABs) of 16 macrocells each, 84 available user I/O pins, and a 36-input programmable interconnect network. The device supports 5V in-system programmability (ISP) via JTAG (IEEE 1149.1), multi-volt I/O interfacing (3.3V and 5V), and per-pin programmable slew rate and open-drain control. Each macrocell provides a programmable flip-flop with D, T, JK or SR modes, plus configurable product-term steering for combinatorial or registered outputs.

The MAX 7000S architecture uses Altera's classic second-generation EEPROM-based logic elements with a unified global routing pool, which yields predictable timing independent of design placement. The 7.5 ns tPD figure is valid across commercial temperature and voltage ranges, allowing the device to replace multiple discrete TTL/CMOS 74-series packages while reducing board area and improving design flexibility through software-based logic changes.

Typical applications include address decoding and bus-interface logic in microprocessor and DSP systems, peripheral glue logic in embedded designs, state-machine controllers, and 5V I/O expansion for ASICs and microcontrollers. Industrial automation and legacy equipment upgrades also leverage the MAX 7000S for backward-compatible 5V logic integration.

When designing with the EPM7128STC100-7, ensure each I/O pin's output enable and slew rate are configured in the Quartus II / MAX+PLUS II fitting tool to match signal integrity targets. JTAG chain ordering must be defined to allow in-field reprogramming, and unused pins should be set to "As input tri-stated" to minimize power and EMI.

Applications typiques

EPM7128STC100-7 convient pour 6 applications: Microprocessor Address Decoding and Bus Glue Logic, DSP and ASIC Peripheral Expansion, Industrial Control State-Machine Controllers, Legacy 5V I/O Expansion for Microcontrollers, Telecom and Networking Glue Logic, Test and Measurement Front-End Logic.

🖥️

Microprocessor Address Decoding and Bus Glue Logic

The EPM7128STC100-7 is well-suited to microprocessor address decoding and bus-interface glue logic. Its 128 macrocells and 84 user I/Os can replace dozens of 74-series packages while fitting into one 100-pin TQFP. The 7.5 ns tPD ensures chip-select and interrupt signals propagate before the next memory cycle, and the non-volatile EEPROM boot means the decoder is active at power-on with no boot delay. Pair it with a 5V host MCU such as the 8051 or 68k family; the 5V core voltage matches the host rail directly, eliminating level shifters.

🔧

DSP and ASIC Peripheral Expansion

In DSP and ASIC systems, the EPM7128STC100-7 provides flexible peripheral expansion, implementing FIFO controllers, custom serial interfaces (UART/SPI/I2C bridges), and timing generators that the host processor cannot efficiently handle in software. The 128 macrocells comfortably fit a multi-channel UART plus DMA handshaking logic. With 84 I/Os and 5V native signalling, it interfaces directly to legacy peripheral ICs without level translation, simplifying PCB layout. The JTAG ISP allows in-field firmware upgrades over the same JTAG chain used for the host DSP.

🏭

Industrial Control State-Machine Controllers

The EPM7128STC100-7 is widely used in industrial control state machines and discrete-logic replacement in PLCs, motor controllers, and process automation equipment. Its deterministic 7.5 ns tPD and 125 MHz internal frequency guarantee cycle-accurate control of relays, contactors, and PWM signals. The non-volatile EEPROM boot and 5V I/O tolerance match the industrial 24V-interface backplane designs after opto-isolation. Designers appreciate the ability to modify state machines via JTAG ISP without pulling boards from service.

📱

Legacy 5V I/O Expansion for Microcontrollers

The EPM7128STC100-7 adds general-purpose 5V I/O expansion to 3.3V microcontrollers. A modern Cortex-M or RISC-V host can offload keypad scanning, LCD control, and LED multiplexing to the CPLD, freeing the MCU to focus on application logic. The 84 user I/Os map directly to 7-segment displays, matrix keypads, and GPIO expanders. Because MAX 7000S supports multi-volt I/O on selected banks, the CPLD can bridge a 3.3V MCU to a 5V peripheral bus with no external translator. The instant-on EEPROM boot enables display and keypad handling at the earliest power-on moment.

🌐

Telecom and Networking Glue Logic

In telecom and networking line cards, the EPM7128STC100-7 implements custom PHY/MAC glue logic, clock muxes, and interrupt aggregators that do not warrant a full FPGA. The 84 I/Os connect to multi-gigabit transceivers, switch fabric ports, and management EEPROMs with deterministic timing suitable for synchronous buses. The 5V I/O matches legacy TDM buses, and the JTAG chain integration simplifies board-level boundary-scan testing during manufacturing. The non-volatile boot ensures the network element reaches a safe state at power-on before any software runs.

📺

Test and Measurement Front-End Logic

In bench-top test and measurement equipment, the EPM7128STC100-7 implements front-panel scan matrix control, trigger conditioning, and counter prescalers that need fast deterministic response. The 7.5 ns tPD keeps trigger latency well below the instrument's measurement uncertainty, and the 84 I/Os scan 7-segment displays, rotary encoders, and 4x4 matrix keypads simultaneously. The 5V I/O is ideal for legacy backplanes, and JTAG ISP allows firmware upgrades without opening the enclosure. Engineers can prototype measurement algorithms in a familiar Quartus environment with no MCU firmware loop.

What is the operating voltage of the EPM7128STC100-7?
The EPM7128STC100-7 operates from a single 5V supply (VCCINT = 5 V). The MAX 7000S family supports multi-volt I/O on selected pins for 3.3V and 5V interface levels. According to the Altera MAX 7000 Programmable Logic Device Family datasheet, all VCC pins must be tied to a clean 5V rail with 0.1uF decoupling placed as close to the package as possible.
How many user I/O pins does the EPM7128STC100-7 provide?
The EPM7128STC100-7 provides 84 user I/O pins within its 100-pin TQFP package. The remaining pins are dedicated to JTAG (TDI, TDO, TMS, TCK), power (VCC), and ground (GND). The 84 I/Os support individual direction, slew rate, and open-drain configuration through the Quartus II or MAX+PLUS II development software.
Where can I buy the EPM7128STC100-7 online?
The EPM7128STC100-7 is available through major distributors including DigiKey (part 544-1785-ND), Mouser, Octopart listings, Xecor, Vyrian, and Jotrin Electronics. As of 2026-09-13, distributor inventory is constrained because the part is mature/obsolete; lead times for new stock typically range 8-14 weeks, and pricing for the qty-1 unit tier is approximately $18.50 per the latest distributor data.
What is the lead time for EPM7128STC100-7?
As of 2026-09-13, the lead time for new EPM7128STC100-7 orders is typically 8-14 weeks through authorized distributors because the part is marked obsolete/end-of-life by Intel. Excess and authorized aftermarket suppliers (Jotrin, Vyrian, Veswin, Xecor) often have stock at premium pricing. For new designs, consider the pin-compatible EPM7128AETC100-7 from the MAX 7000AE family as an active alternative.
Is the EPM7128STC100-7 in stock at major distributors?
As of 2026-09-13, distributor stock is limited. DigiKey historically lists the part under 544-1785-ND; Mouser and Octopart aggregate listings from 22 distributors. Current availability fluctuates because the EPM7128STC100-7 is marked obsolete; check the distributor inventory feed directly for real-time stock, or request a quote from authorized aftermarket suppliers who specialize in legacy Intel/Altera components.
What is the difference between EPM7128STC100-7 and EPM7128AETC100-7?
The EPM7128STC100-7 is from the original MAX 7000S family (5V core, 7.5 ns tPD), while the EPM7128AETC100-7 is from the MAX 7000AE family (3.3V core, faster tPD, multi-volt I/O, lower power). Both share the same 100-pin TQFP package and 128 macrocell architecture, but the AE family offers enhanced ISP, JTAG, and faster timing. According to the ETEI comparison data, the two are pin-compatible but differ in core voltage and propagation delay.
EPM7128STC100-7 vs EPM7128SQC100-7 - which is better for 5V designs?
For 5V designs, the EPM7128STC100-7 (TQFP-100) is the better choice because it is a native 5V part with 84 user I/Os and 7.5 ns tPD. The EPM7128SQC100-7 is also a 5V part but is offered in an FBGA-100 package for space-constrained designs. According to the Xecor comparison data, both share the 128 macrocell MAX 7000S architecture; pick STC100 for standard TQFP reflow and SQC100 when PCB area is at a premium.
When should I choose the EPM7128STC100-7 over a newer MAX 7000AE part?
Choose the EPM7128STC100-7 when you are maintaining a legacy 5V system whose firmware, board layout, and JTAG programming files are already validated for the MAX 7000S family, or when a customer requirement mandates an exact BOM match. Choose a MAX 7000AE variant (such as EPM7128AETC100-7) for new designs because AE parts are active, support 3.3V core, and offer faster tPD. The two are not drop-in compatible at the firmware/Quartus project level.
Is the EPM7128STC100-7 suitable for new industrial designs in 2026?
The EPM7128STC100-7 is marked obsolete by Intel, so it is not recommended for new industrial designs starting in 2026. For new designs, use an active equivalent such as the EPM7128AETC100-7 (MAX 7000AE, 3.3V core), or migrate to the MAX II family (EPM240T100C5N) for lower power. The EPM7128STC100-7 remains appropriate for maintenance, repair, and legacy system upgrades where a drop-in replacement is required.
What is the best drop-in replacement for the EPM7128STC100-7?
The best drop-in replacement for the EPM7128STC100-7 in the same 100-pin TQFP package is the EPM7128STC100-10N (slower 10 ns tPD but pin-compatible) from Intel/Altera. For a faster upgrade with multi-volt I/O, use the EPM7128AETC100-7 from the MAX 7000AE family - same TQFP-100 footprint, same 128 macrocells, but 3.3V core and improved ISP. According to pcbsync.com pinout references, both alternatives share the EPM7128STC100-7 pinout in the TQFP-100 package.
Can the EPM7128STC100-7 be replaced with a non-Intel part?
Direct pin-to-pin cross-brand replacement is not practical for the EPM7128STC100-7 because MAX 7000S uses proprietary Altera/Intel JTAG and Quartus/MAX+PLUS II programming flows. Lattice ispMACH 4000 (e.g., LC4128ZE-5TN100C) is a third-party CPLD with similar macrocell count and TQFP-100 footprint but requires a different toolchain (ispLEVER), a different JTAG BSDL, and may not be firmware-compatible. Verify pin mapping carefully before attempting a non-Intel swap.
Where can I download the EPM7128STC100-7 datasheet PDF?
The EPM7128STC100-7 datasheet (MAX 7000 Programmable Logic Device Family datasheet, originally published by Altera Corporation and now maintained by Intel) can be downloaded from the Altera/Intel legacy document archive, the all-datasheet mirror at alldatasheet.com (under Altera part 527349), or the FindIC datasheet portal. The document is approximately 478 KB to 1.49 MB depending on the mirror, and contains pinout, electrical characteristics, and timing specifications for the entire MAX 7000S family.
Where can I find the EPM7128STC100-7 pinout?
The EPM7128STC100-7 pinout for the 100-pin TQFP package is documented in the Altera MAX 7000 Programmable Logic Device Family datasheet, available on alldatasheet.com (part ID 527349), datasheetq.com (39-page PDF), and Intel's legacy documentation archive. The pcbsync.com EPM7128 series guide also provides a visual pinout map. The TQFP-100 layout reserves JTAG pins (TDI/TDO/TMS/TCK), dedicated VCC/GND, and 84 general-purpose user I/O pins.
What are the key specifications of EPM7128STC100-7 engineers should know?
The EPM7128STC100-7 is a 128-macrocell, 84-I/O MAX 7000S CPLD with 7.5 ns tPD, 125 MHz maximum internal frequency, and 2,500 usable gates in a 100-pin TQFP, operating from a single 5V supply with commercial 0C to +70C temperature range. It supports in-system programming via IEEE 1149.1 JTAG and stores configuration in on-chip EEPROM. Key trade-offs: instant-on non-volatile boot, deterministic timing, and 5V native I/O versus modern 3.3V parts with lower power.

Guide de sélection

Choose the EPM7128STC100-7 when you are maintaining a legacy 5V system whose PCB, firmware, and Quartus/MAX+PLUS II toolchain are already validated for the MAX 7000S family, or when a customer requires an exact BOM match for production spares. The 7.5 ns tPD and 125 MHz internal frequency are well-matched to address decoding, glue logic, and state-machine tasks at 5V. For new 5V designs in 2026, prefer the pin-compatible EPM7128STC100-10N for lower cost if timing margin allows, or migrate to the MAX 7000AE family (EPM7128AETC100-7) for active lifecycle status and 3.3V core support. Avoid the EPM7128STC100-7 in greenfield designs because the part is marked obsolete; use it for repair and legacy maintenance only.

  • Faster tPD than 10 ns and 15 ns speed grades (vs EPM7128STC100-10N / EPM7128STC100-15N)
  • Native 5V core supply versus 3.3V AE family (vs EPM7128AETC100-7)
  • Larger TQFP-100 footprint with 84 I/Os versus PLCC-84 with 68 I/Os (vs EPM7128SLC84-7N)
  • Lower cost than legacy 7 ns speed grades (vs EPM7128STC100-6N)

Notes de conception

The EPM7128STC100-7 requires a clean 5V VCC rail on all VCC pins (1, 14, 31, 47, 63, 79, 95 in the TQFP-100 package). Estimated: at full toggle activity on all 84 I/Os with 25 pF loads at 50 MHz, ICC can reach approximately 300-400 mA. Place one 0.1uF ceramic decoupling capacitor adjacent to every VCC/GND pair, plus a single 10uF tantalum bulk capacitor near the package. Inrush during ISP programming can briefly draw 500 mA - ensure the regulator has adequate headroom.

Place all 7 VCC pins and 7 GND pins on a continuous power plane under the TQFP-100 footprint. Keep the JTAG header (TDI/TDO/TMS/TCK on pins 96-99) routed with 4 dedicated signal traces and a TCK pull-down to ground if not actively driven. Use a 100-ohm series terminator on TDO if the JTAG cable exceeds 100 mm. Maintain at least 5 mm clearance between TQFP-100 traces and adjacent connectors to simplify probe access during in-system programming.

Do not confuse the EPM7128STC100-7 (MAX 7000S, 5V core) with the EPM7128AETC100-7 (MAX 7000AE, 3.3V core); the AE variant requires a different core voltage and JTAG programming setup. Also, the pinout table in the Altera MAX 7000 datasheet includes dedicated global clock pins (GCLK1, GCLK2, GCLK3) and dedicated OE pins (OE1, OE2, OE3) that must be honored; treating them as regular I/Os prevents proper global clock routing. Refer to the pcbsync.com MAX 7000 series guide for the exact TQFP-100 pin assignment.

For high-speed designs above 50 MHz, route all user I/O signals on the top layer directly under the package fanout with controlled impedance (typically 50 ohm single-ended). Use via-stitching around the TQFP-100 ground pad to maintain a low-impedance return path; the exposed die-attach paddle is internally grounded. Avoid running high-slew signals (clocks, fast edges) parallel to JTAG traces for more than 25 mm to prevent crosstalk into the programming chain.
