EPM3128ATC144-5 نظرة عامة

The Altera EPM3128ATC144-5 is a member of the MAX 3000A family of high-performance, low-cost CMOS EEPROM-based complex programmable logic devices (CPLDs), delivering 128 macrocells, 2,500 system gates, and a 7.5 ns propagation delay in a 144-pin TQFP (TQ144) package rated for commercial 0C to 70C operation. Built on a multi-volt, multi-vendor in-system programmable (ISP) architecture, the device operates from a 3.3 V core supply and supports 5.0 V, 3.3 V, and 2.5 V multi-volt I/O interfacing, allowing direct connection to legacy and modern logic families without external level shifters. The MAX 3000A non-volatile ISP is compliant with the IEEE Std. 1532 specification, allowing concurrent ISP from multiple PLD vendors.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell arrays on a single die, connected through a programmable interconnect matrix. The MAX 3000A family belongs to the broader hierarchy: CPLD -> programmable logic device (PLD) -> logic IC -> semiconductor. CPLDs are typically chosen over FPGAs for glue-logic, bus-interface, state-machine, and power-up deterministic applications because their EEPROM configuration cells boot in microseconds, not milliseconds, and retain state without external boot memory.

Key features include 128 macrocells arranged in 8 logic array blocks (LABs), 250 usable I/O pins within the package (with 96 user I/Os exposed externally per the 144-pin TQFP), two global clock networks with clear and clock-enable control on every register, programmable interconnect, JTAG boundary-scan testing, and built-in IEEE 1149.1 (JTAG) support. The -5 speed grade corresponds to a 7.5 ns pin-to-pin propagation delay (tPD), supporting designs with up to 192.3 MHz internal counter performance. Power consumption is typically 130 mA at 3.3 V, with standby current as low as 5 mA.

The architecture is built on 0.30 um CMOS EEPROM technology with four layers of metal interconnect, exposing the user to a deterministic timing model. The MAX 3000A delivers predictable, simulator-friendly timing across Pterms, LABs, and the interconnect matrix (PIA), with no hidden routing delays - a property that distinguishes it from SRAM-based FPGAs.

Typical applications include bus-interface bridging, address decoding and DMA control in industrial backplanes, glue-logic replacement for 7400-series TTL in legacy designs, peripheral controllers in printers and scanners, and LED display multiplexing. Designers frequently choose the MAX 3000A family when a low-cost, non-volatile, deterministic-logic solution is needed in a familiar 3.3 V ecosystem.

When designing with the EPM3128ATC144-5, ensure each I/O bank has its VCCIO rail properly decoupled and matched to the driven logic level (3.3 V or 2.5 V), because mixing I/O standards in the same bank can damage the device. Provide a minimum of 0.1 uF ceramic bypass on each VCC and VCCIO pin, and consult the MAX 3000A Family Data Sheet for ISP programming voltage sequencing when using JTAG.

التطبيقات النموذجية

EPM3128ATC144-5 مناسب لـ 6 التطبيقs: Industrial Bus Interface Bridging, Glue-Logic Replacement for 7400-Series TTL, Printer and Scanner Peripheral Controllers, LED Display Multiplexing and Panel Drivers, Legacy Industrial Control Boards, Address Decoding and DMA Arbitration.

🏭

Industrial Bus Interface Bridging

The EPM3128ATC144-5 bridges legacy 5 V TTL peripherals to a 3.3 V microcontroller or FPGA bus, with its multi-volt I/O handling 5.0 V, 3.3 V, and 2.5 V logic on the same die. The 128 macrocells and 96 user I/Os comfortably absorb glue logic, address decoding, and handshake-protocol state machines that previously required multiple 7400-series TTL chips, while the 7.5 ns tPD keeps bus-to-bus latency negligible. Unlike SRAM-based FPGAs, the EEPROM-based MAX 3000A boots in microseconds, so power-on deterministic logic is available immediately, which is critical for backplane arbitration in industrial controllers.

🔧

Glue-Logic Replacement for 7400-Series TTL

Engineers use the EPM3128ATC144-5 to consolidate 7400-series discrete logic - such as 74LS138 decoders, 74LS245 transceivers, and 74LS374 registers - into a single non-volatile CPLD. With 2,500 system gates, 128 macrocells, and 32 product terms per macrocell, the device absorbs equivalent circuitry of 15-25 discrete TTL packages while improving timing predictability. The 3.3 V core with multi-volt I/O allows direct interface to both 5 V and 3.3 V devices on the same board, and the IEEE Std. 1532 ISP permits in-system firmware updates without removing the chip from the PCB.

🖥️

Printer and Scanner Peripheral Controllers

The EPM3128ATC144-5 serves as a peripheral controller in legacy printers and document scanners, handling stepper-motor sequencing, sensor-multiplexing, and high-speed parallel-data routing between the imaging ASIC and the main processor. Its 7.5 ns tPD and 192.3 MHz maximum internal frequency handle parallel-port data rates that exceed 50 MHz, while the 96 user I/Os accommodate multiple motor-driver signals and opto-sensor inputs without external buffers. The non-volatile EEPROM configuration retains controller logic across power cycles, enabling instant paper-feed and image-acquisition startup, which is preferred over SRAM FPGAs that require boot-load delay.

💡

LED Display Multiplexing and Panel Drivers

The EPM3128ATC144-5 drives large LED dot-matrix panels by time-multiplexing row/column lines and generating per-frame refresh logic, taking advantage of its 96 user I/Os and 7.5 ns tPD for flicker-free scanning rates up to 1 kHz. The two global clock networks with per-register clock-enable control let designers implement hardware PWM dimming on each row, while the multi-volt I/O interfaces directly with 5 V LED-driver shift registers without level shifters. The non-volatile configuration stores display-pattern tables in adjacent macrocells, eliminating the need for external boot memory.

🏭

Legacy Industrial Control Boards

The EPM3128ATC144-5 is widely deployed in legacy industrial control boards where 25-year design lifecycle support is critical, including PLC backplanes, motor-drive signal conditioning, and SCADA interface cards. Its 0C to 70C commercial temperature range covers most factory-floor environments, while the EEPROM non-volatile configuration eliminates the reliability risk of SRAM-based boot failure in unattended installations. Engineers maintain installed bases with this part because the 144-pin TQFP footprint has been standardized across the MAX 3000A family, simplifying board rev management.

💾

Address Decoding and DMA Arbitration

The EPM3128ATC144-5 is used for high-speed address decoding and DMA arbitration in embedded systems, where its 7.5 ns tPD and deterministic timing allow wait-state generation and bus-grant logic with sub-10 ns latency. The 32 product terms per macrocell accommodate wide-decode trees (24-bit to 32-bit address spaces) in a single logic level, avoiding the multi-level decode penalty that discrete PAL devices incur. The 2,500 system gates and 8 LABs provide the headroom needed for both combinatorial decoding and registered state-machine channels on the same die.

What is the propagation delay of the EPM3128ATC144-5?
The EPM3128ATC144-5 has a pin-to-pin propagation delay (tPD) of 7.5 ns, corresponding to the -5 speed grade in the MAX 3000A family. According to the Altera MAX 3000A Family Data Sheet, this speed grade also supports internal counter frequencies up to 192.3 MHz, making the part suitable for bus-interface and state-machine designs where deterministic timing is required.
How many macrocells and logic array blocks does the EPM3128ATC144-5 contain?
The EPM3128ATC144-5 contains 128 macrocells organized into 8 logic array blocks (LABs), giving it a usable gate capacity of 2,500 system gates. Each macrocell provides 32 product terms for combinatorial or registered logic, with two global clock networks and per-register clock-enable control, per the Altera MAX 3000A datasheet.
Is the EPM3128ATC144-5 still in production?
The EPM3128ATC144-5 is listed as Obsolete by Arrow Electronics and is no longer in active production by Altera (now Intel FPGA). Distributors such as DigiKey and Mouser still list the part, but new inventory is limited to remaining channel stock and the secondary market, so engineers should design with care and consider newer MAX II or MAX V alternatives for new designs.
What is the difference between EPM3128ATC144-5 and EPM3128ATC144-5N?
The EPM3128ATC144-5N is the lead-free (Pb-free) version of the EPM3128ATC144-5, otherwise identical in pinout, macrocell count, and speed grade. The -5N variant uses lead-free terminations compliant with RoHS soldering profiles, while the original -5 is not RoHS compliant per the Arrow distributor listing. Both share the same 144-pin TQFP package and are drop-in compatible.
Is the EPM3128ATC144-5 pin-compatible with the EPM3128ATC144-10?
Yes, the EPM3128ATC144-5 and EPM3128ATC144-10 are pin-to-pin compatible in the same 144-pin TQFP package; the only difference is the speed grade (-5 is 7.5 ns tPD, -10 is 10 ns tPD). The -10 variant is slower and typically cheaper, so the -10 can be substituted for the -5 when timing margins allow, but the -5 cannot reliably replace the -10 in already-shipping designs.
What package does the EPM3128ATC144-5 use?
The EPM3128ATC144-5 ships in a 144-pin Thin Quad Flat Pack (TQFP) with 0.5 mm lead pitch (some sources list 1.0 mm pitch - consult the device marking), measuring approximately 22x22 mm. The '144' suffix in the part number explicitly denotes the 144-pin TQFP package, distinguishing it from the 100-pin variants (EPM3128ATC100) and 256-pin variants.
What is the operating voltage of the EPM3128ATC144-5?
The EPM3128ATC144-5 operates from a 3.3 V core supply and supports 5.0 V, 3.3 V, and 2.5 V multi-volt I/O interfacing. Per the Altera datasheet, this multi-volt I/O allows direct connection to legacy TTL (5 V) and modern low-voltage logic without external level shifters, simplifying mixed-voltage glue-logic designs.
Where can I download the EPM3128ATC144-5 datasheet PDF?
The official Altera MAX 3000A Family Data Sheet is available as a PDF from the Altera archive at https://www.alterasemi.com/datasheet/alterasemi/EPM3128ATC144-5.pdf and from secondary sources such as Alldatasheet (715 KB, 46-page PDF). The datasheet contains full DC characteristics, AC timing, JTAG/ISP instructions, and 144-pin TQFP pin assignments.
Where can I buy the EPM3128ATC144-5 today?
The EPM3128ATC144-5 is available from authorized distributors including DigiKey (part 544-1167-ND), Mouser, Arrow (where it is listed as Obsolete), and secondary-market brokers such as Vyrian, Veswin, and LoveChip. Pricing as of 2026-09-12 ranges from approximately USD 8.75 at qty-1 down to USD 4.85 at qty-1000, subject to remaining stock and supply-chain volatility.
What is the current price of the EPM3128ATC144-5?
As of 2026-09-12, the EPM3128ATC144-5 lists at approximately USD 8.75 in single-piece quantity on the open market, with volume pricing of USD 4.85 at qty-1000. Pricing fluctuates because the part is obsolete - small-lot orders from secondary-market brokers typically carry premium pricing, and large-lot purchases should be quoted through franchised distributors.
What is the lead time for the EPM3128ATC144-5?
Lead time for the EPM3128ATC144-5 is variable because the part is obsolete; franchised distributors such as DigiKey list stock-only availability, while secondary-market brokers typically ship from US or Asian warehouse stock within 1 to 4 weeks. For production volumes, expect to negotiate via formal quote and verify parts authenticity through factory-packaging inspection.
What is the best drop-in replacement for the EPM3128ATC144-5?
The best drop-in replacement for the EPM3128ATC144-5 is the EPM3128ATC144-5N, which is the lead-free version of the same die in the same 144-pin TQFP package, or the slower EPM3128ATC144-10 / -10N family members (also in TQFP-144) when timing margins allow. For modern designs, engineers should evaluate the MAX II or MAX V families (EPM240, EPM570) as next-generation, lower-power non-volatile CPLD alternatives.
What are the key specifications of the EPM3128ATC144-5 that engineers should know?
Key specifications of the EPM3128ATC144-5 are: 128 macrocells, 8 LABs, 96 user I/Os, 2,500 system gates, 7.5 ns tPD, 192.3 MHz maximum internal frequency, 3.3 V core, 5.0/3.3/2.5 V multi-volt I/O, 144-pin TQFP package, 0C to 70C commercial temperature range, EEPROM non-volatile configuration, and IEEE 1532 ISP. These figures come from the Altera MAX 3000A Family Data Sheet.
What is the difference between EPM3128ATC144-5 and EPM3128ATC144-10N?
Both the EPM3128ATC144-5 and EPM3128ATC144-10N are pin-to-pin compatible in the 144-pin TQFP package with 128 macrocells, but the -5 has a 7.5 ns tPD (faster, -5 speed grade) while the -10N has a 10 ns tPD (-10 speed grade, lead-free). The -10N is typically cheaper and more available; the -5 is faster and more suitable for tight-timing bus-interface designs.
Is the EPM3128ATC144-5 RoHS compliant?
The EPM3128ATC144-5 is NOT RoHS compliant per the Arrow Electronics distributor listing, which explicitly states 'EU RoHS Not Compliant.' Engineers designing for EU markets should select the EPM3128ATC144-5N (lead-free, N-suffix) variant or migrate to a MAX II/MAX V family CPLD that is fully RoHS and REACH compliant for current production.

دليل الاختيار

Choose the EPM3128ATC144-5 when you need a deterministic, non-volatile 128-macrocell CPLD in a 144-pin TQFP with 7.5 ns tPD for legacy industrial designs where lead-free compliance is not required. Choose the EPM3128ATC144-5N if RoHS compliance is mandatory for EU markets. Choose the EPM3128ATC144-10 / -10N for cost-down where the 25% slower speed grade is acceptable. For new designs, evaluate the MAX II (EPM240, EPM570) or MAX V family for lower power and active production status. Avoid mixing MAX 3000A density points on the same PCB footprint because pinout changes between EPM3128, EPM3256, and EPM3512 in the same 144-pin TQFP package.

ملاحظات التصميم

The EPM3128ATC144-5 requires both a 3.3 V VCC (core) rail and a separate VCCIO (I/O) rail for multi-volt I/O operation. Decouple each VCC and VCCIO pin with a 0.1 uF ceramic capacitor placed as close to the package as possible, and add a 10 uF bulk tantalum or ceramic capacitor near the device to handle ISP-induced transients. Mis-wiring VCCIO to 5 V while VCC is at 3.3 V is a common failure mode - verify bank voltages against the MAX 3000A datasheet before power-on.

Route JTAG signals (TCK, TMS, TDI, TDO) with controlled impedance and keep them away from high-speed clocks and switching I/O to avoid ISP programming failures. Place the JTAG header or connector at the edge of the PCB for production-line programming access. For 144-pin TQFP, use 0.25 mm trace width with 0.5 mm pitch escape routing to break out the inner I/O pins, and provide at least 4 ground pads on the inner ring for return-current continuity.

Do not assume that any 144-pin TQFP from the MAX 3000A family has the same pinout; the EPM3128ATC144-X, EPM3256ATC144-X, and EPM3512ATC144-X differ in pin assignments because internal LAB organization changes between density points. Also, the EPM3128ATC144-5 is not RoHS compliant per the Arrow distributor listing - do not place it on RoHS-only PCBs. Use the lead-free EPM3128ATC144-5N for EU-market products, and verify pinout against the specific device datasheet before laying out the PCB footprint.

For designs using all 96 user I/Os at 5 V TTL levels simultaneously switching, add series resistors (22-33 ohm) near the CPLD outputs to dampen transmission-line reflections on cables or long PCB traces. The MAX 3000A output drive strength is approximately 8-12 mA per pin - adequate for TTL but marginal for long cables. Use a ground-reference trace alongside each clock signal and keep clock traces under 50 mm to avoid skew.
