EPM3128ATC100-5N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL/GAL-like macrocell arrays with a central programmable interconnect matrix. CPLDs sit hierarchically between simple SPLDs (PALs/GALs) and large FPGAs, offering deterministic timing, instant-on EEPROM configuration, and densities in the hundreds-to-thousands of gates range. The MAX 3000A architecture used in the EPM3128ATC100-5N is fabricated on 5.0 V-tolerant EEPROM CMOS technology with 3.3 V core and I/O supply rails, providing up to 10,000 usable gates and IEEE Std. 1532-compliant in-system programmability (ISP).
Key features include 128 macrocells organized in 8 Logic Array Blocks (LABs) of 16 macrocells each, 80 user I/Os with individual programmable slew rate and bus-hold options, JTAG boundary-scan test (IEEE 1149.1), 3.3 V or 2.5 V VCCIO selectable output levels, and multiVolt I/O support for interfacing with 5.0 V, 3.3 V, and 2.5 V systems. The device is offered in commercial 0 C to +70 C temperature grade and supports 100% in-system programmability through the JTAG interface, eliminating the need for external programmers.
The EPM3128ATC100-5N employs an enhanced MAX architecture with a global interconnect matrix that routes LAB-to-LAB signals with predictable, deterministic delays independent of placement. Each macrocell contains a programmable AND/OR array, a flip-flop with programmable clear/preset, and a configurable I/O cell. The 5 ns speed grade (the -5 suffix) targets glue-logic applications such as address decoding, bus arbitration, interrupt handling, and register-based state machines where fast deterministic timing is required.
Typical applications include bus interface bridging in telecom and networking equipment, address decoding and interrupt management in embedded systems, register/glue logic replacement in industrial controllers, and PCI/ISA bus interface logic in legacy computer designs. The 100-pin TQFP package provides a familiar footprint for drop-in compatibility with the broader MAX 3000A family and is widely supported by the Quartus II / MAX+PLUS II development toolchains.
When designing with this device, ensure proper decoupling with 0.1 uF and 10 uF capacitors placed close to each VCC and VCCIO pin. The JTAG TMS, TCK, TDI, and TDO pins require 4.7 kohm pull-up resistors for reliable in-system programming. For multi-voltage designs, the VCCIO pins can be tied to 2.5 V to support 2.5 V logic families. The -5 speed grade balances speed and cost; for higher performance, consider the -4 grade, and for lower power/cost, the -7 or -10 grades are pin-compatible alternatives.
This page synthesizes distributor stock and pricing data, a verified list of drop-in TQFP-100 alternatives within the MAX 3000A family, and practical design notes that complement the official MAX 3000A Family Data Sheet and the Quartus II programming handbook.

Applications typiques
EPM3128ATC100-5N convient pour 7 applications: Address Decoding and Chip-Select Generation, Bus Interface Bridging and Protocol Conversion, Industrial Control and Factory Automation, Telecom Equipment Glue Logic, Embedded System Interrupt Management, Legacy Computer and Peripheral Replacement, Test and Measurement Instrumentation.
Address Decoding and Chip-Select Generation
The EPM3128ATC100-5N is widely deployed in embedded systems for generating chip-select and address-decode signals from a microprocessor bus. With 128 macrocells and 5 ns propagation delay, it can decode complex memory maps including bank-switched Flash, SRAM, and peripheral selects in real time without wait states. The 80 user I/Os accommodate wide address buses (24+ bits) and multiple peripheral select outputs. The deterministic 5 ns tPD ensures the chip-select is valid well within typical MCU access cycles (e.g., 70-100 ns for 8051, ARM7), and the non-volatile EEPROM configuration means the decode logic is available instantly at power-up without bootloader delay. Typical implementation uses the device to consolidate 4-6 discrete 74HC/74FCS decoder ICs into a single CPLD, reducing board area and BOM cost. Quartus II schematic entry with AHDL/VHDL captures the Boolean decode expressions.
Recommandé
Bus Interface Bridging and Protocol Conversion
The EPM3128ATC100-5N excels at bridging between legacy and modern bus standards such as PCI-to-ISA, VME-to-PCI, or parallel-FIFO-to-microprocessor bus interfaces. The 5 ns propagation delay is fast enough for 33 MHz PCI bus signal generation including FRAME#, IRDY#, TRDY#, and DEVSEL# timing. With 80 I/Os and 3.3 V/2.5 V VCCIO support, the device can directly interface 3.3 V PCI bus signals and 5.0 V-tolerant inputs allow connection to legacy 5 V peripherals. The EEPROM-based configuration is critical for industrial and telecom systems where instant-on behavior is required without external configuration memory. The device implements bus-master handshaking, address/data multiplexing, and interrupt steering logic in a single chip, replacing dozens of discrete TTL ICs. JTAG boundary scan enables board-level interconnect test.
Recommandé
Industrial Control and Factory Automation
The EPM3128ATC100-5N serves as a versatile glue-logic platform in PLC, motor-control, and factory-automation equipment. The 100-pin TQFP package and commercial 0-70 C temperature grade suit factory-floor cabinet environments. The device implements encoder quadrature decoding, PWM generation, stepper-motor pulse-and-direction sequencing, and safety-interlock logic. Its 128 macrocells can hold complete state machines for machine-cycle control, error detection, and emergency-stop sequencing. The JTAG interface (IEEE 1149.1) allows in-system reconfiguration during commissioning or field upgrades without removing the board from the machine. MultiVolt I/O support enables interfacing to 24 V industrial sensors via external opto-couplers and to 3.3 V MCUs. The deterministic timing of CPLDs (vs. MCU firmware loops) makes them ideal for hard-real-time control loops where microsecond-level response is required.
Recommandé
Telecom Equipment Glue Logic
In telecom infrastructure such as DSLAMs, optical line terminals, and central-office switches, the EPM3128ATC100-5N provides deterministic glue logic between network processors, ASICs, and physical-layer devices. The 5 ns tPD handles TDM bus timing, Utopia/Serial RapidIO interface glue, and framer/mapper configuration. With 80 I/Os, the device can fan-out control signals from a single network processor to multiple PHYs. The EEPROM configuration ensures the system boots without firmware intervention, critical for carrier-grade equipment requiring deterministic startup. The 3.3 V core with 5 V-tolerant I/O allows interfacing to legacy telecom ASICs while keeping power consumption low. IEEE Std. 1532-compliant ISP enables field updates across thousands of deployed units via JTAG.
Recommandé
Embedded System Interrupt Management
The EPM3128ATC100-5N is ideal for priority-encoded interrupt controllers in embedded systems. With 128 macrocells, it can implement a 32-input priority encoder with mask registers, vector generation, and edge/level detection. The 5 ns tPD ensures the interrupt vector is stable within the CPU's interrupt acknowledge cycle. The 80 I/Os allow direct connection to peripheral IRQ outputs (UART, DMA, timers, external interrupts) while presenting a single-vector interface to the host CPU. EEPROM-based configuration means the interrupt map is non-volatile and survives power cycles. The JTAG interface allows live reconfiguration of the interrupt priority map during firmware development, accelerating bring-up. This eliminates the need for discrete 74LS148 priority encoders and 8259A-style interrupt controller ICs.
Recommandé
Legacy Computer and Peripheral Replacement
The EPM3128ATC100-5N is widely used to modernize legacy ISA, VLB, and PCI peripheral cards by replacing obsolete discrete logic and TTL ICs. Designs originally using 20-30 discrete 74LS/74F/74ALS ICs for bus arbitration, wait-state generation, and interrupt steering can be consolidated into a single MAX 3000A CPLD. The 5 ns tPD matches legacy 74F-series timing budgets. The 80 I/Os support 16-bit ISA bus implementation with multiple wait-state, DMA, and interrupt signals. Non-volatile EEPROM configuration means the card boots correctly without external boot ROM or configuration memory, simplifying the BOM. The 3.3 V core with 5 V-tolerant I/O allows direct connection to legacy 5 V bus signaling.
Recommandé
Test and Measurement Instrumentation
In test equipment such as logic analyzers, protocol analyzers, and ATE (Automated Test Equipment), the EPM3128ATC100-5N provides deterministic timing control for stimulus generation, response capture, and handshake sequencing. The 5 ns tPD enables sub-100 MHz pattern generation with precise edge placement. The 80 I/Os support parallel stimulus/response buses up to 40 channels. MultiVolt I/O allows interfacing with both 3.3 V modern DUTs and 5 V legacy devices. The JTAG boundary scan simplifies board-level test of the instrument itself. The EEPROM configuration allows instant power-up into the last-known test state without firmware boot delay, critical for production-line ATE that must cycle power between tests. The device can implement custom protocols such as I2C, SPI, or UART bridges in test fixtures.

- Non-volatile EEPROM configuration for instant-on behavior (vs SRAM-based FPGAs)
Notes de conception
The EPM3128ATC100-5N requires a stable 3.3 V supply for VCCINT (core) and a separate VCCIO rail that can be 3.3 V or 2.5 V. Place a 0.1 uF ceramic decoupling capacitor close to each VCCINT and VCCIO pin, plus a bulk 10-100 uF tantalum or aluminum capacitor near the package. For designs with mixed 3.3 V/2.5 V logic, the VCCIO pins can be split into banks; consult the MAX 3000A datasheet for bank assignments. Inrush current during ISP programming can reach 100-200 mA per VCCINT pin; ensure the regulator has adequate headroom.
The TQFP-100 package has 0.5 mm pitch pins requiring careful PCB layout. Use 0.15 mm/6 mil traces between pads, with ground and power planes on inner layers. Place JTAG connector (TMS, TCK, TDI, TDO) within 50 mm of the CPLD to keep TCK rise times clean. Add 4.7 kohm pull-up resistors on TMS, TDI, and TCK for stable JTAG operation. Keep JTAG traces away from high-speed signal edges to avoid programming glitches. Exposed pad (if present) should be soldered to a grounded copper pour for thermal dissipation.
A common pitfall is assuming the EPM3128ATC100-5N and EPM3128ATC100-5 are interchangeable - the -5N has the 'N' suffix indicating lead-free / RoHS-compliant packaging, while the -5 is leaded. Both share identical pinout and electrical specs but cannot be substituted in RoHS-compliant designs. Another pitfall is overlooking the VCCIO voltage selection: if the VCCIO is set to 2.5 V, the output logic levels are 2.5 V and not 3.3 V, which may cause level-mismatch issues with 3.3 V peripherals. Finally, the device is EEPROM-based with 100+ program/erase cycles; excessive in-system reprogramming can wear out the cells.
