EPM3064ALC44-4 جائزہ

The Altera (Intel) EPM3064ALC44-4 is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, delivering 64 macrocells organized in 2 Logic Array Blocks (LABs) with 34 user I/O pins in a 44-pin PLCC (Plastic Leaded Chip Carrier, J-Lead) package. It features a pin-to-pin propagation delay of 4.5 ns, making it suitable for high-speed glue-logic, bus interfacing, and state-machine replacement in industrial and commercial designs. The device supports 3.3-V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, enabling field upgrades without removing the part from the board.

A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL/GAL-like macrocell blocks with a central interconnect matrix. Within the programmable logic hierarchy, the EPM3064 sits at the low-density end, below FPGAs and higher-density CPLDs; it is best understood as a glue-logic and bus-interface replacement IC, distinct from microcontrollers, ASICs, and discrete logic gates. The MAX 3000A architecture supports 2.5-V, 3.3-V, or 5.0-V I/O pin operation via separate VCCINT and VCCIO pins, giving designers flexible interfacing with both legacy 5V and modern 3.3V logic families.

Key features include 64 macrocells, 34 I/O pins, 4.5 ns tPD, an internal JTAG-based ISP engine, and EEPROM-based configuration that retains logic without an external boot PROM. The PLCC-44 (J-Lead) package is socket-compatible with industry-standard 44-pin PLCC sockets, easing prototyping and rework on through-hole or socketed boards.

Architecture-wise, the EPM3064 uses a CMOS EEPROM process with Altera's classic MAX interconnect matrix, providing predictable timing with deterministic pin-to-pin delays regardless of logic utilization. This makes timing closure straightforward compared to SRAM-based FPGAs that require external configuration memory.

Typical applications include bus-interface bridging (e.g., 5V to 3.3V level shifting), address decoding, peripheral chip-select generation, glue logic between microcontrollers and peripherals, and legacy system upgrades. The wide I/O voltage range also suits industrial control, instrumentation, and telecommunications backplane glue.

When designing with the EPM3064ALC44-4, use the Altera/Intel Quartus II programmer or legacy MAX+PLUS II toolchain (the device is supported by classic Altera design software). JTAG ISP requires four dedicated pins (TDI, TDO, TMS, TCK) plus a VCCIO reference. Decouple VCCINT and VCCIO with 0.1 uF ceramic capacitors placed close to the pins.

عام استعمالات

EPM3064ALC44-4 کے لیے موزوں ہے 6 ایپلیکیشنs: Glue Logic and Chip-Select Decoding, 5V to 3.3V Level Translation Bridges, State Machine Replacement, Industrial Control and Instrumentation, Legacy System Upgrade and Bridging, Prototype and Educational Development.

🔧

Glue Logic and Chip-Select Decoding

The EPM3064ALC44-4's 64 macrocells and 34 I/O pins are well matched to classic glue-logic tasks such as address decoding, chip-select generation, and bus-interfacing between microcontrollers, memories, and peripherals. With a 4.5 ns tPD the part introduces minimal delay into critical control paths, replacing 3-5 discrete 74-series logic packages while reducing board area. The MAX 3000A EEPROM-based non-volatile configuration means no external boot PROM is needed and the design powers up in a known state - essential for deterministic system bring-up in embedded boards.

🌐

5V to 3.3V Level Translation Bridges

Because the EPM3064ALC44-4 supports 2.5-V, 3.3-V, and 5.0-V I/O operation via separate VCCIO banks, it serves as a flexible bus bridge between legacy 5V peripherals (e.g., 8051 microcontrollers, ISA-style buses) and modern 3.3V ASICs or ASICs. Each I/O pin can be configured individually as input or output with a wide hysteresis range, and the 4.5 ns propagation delay supports modest-speed buses (PCI, PC/104, parallel memory). The PLCC-44 socket-compatible package simplifies field retrofit of legacy industrial controllers.

🏭

State Machine Replacement

Complex sequential control logic - e.g., washing-machine controllers, vending-machine dispensing sequences, or industrial sequencers - is well served by the EPM3064ALC44-4's 64 macrocells of EEPROM-based logic. Designers replace 4-7 MSI TTL packages (74LS161 counters, 74LS151 muxes, 74LS74 flip-flops) with a single 44-pin PLCC part, simplifying the BOM and PCB while improving reliability (fewer solder joints). The 4.5 ns tPD enables tight sequencing with microsecond-scale step times, and the JTAG ISP allows late firmware revisions without board rework.

🏭

Industrial Control and Instrumentation

In PLC backplanes, motor-control boards, and bench-top instrumentation, the EPM3064ALC44-4 provides deterministic timing for PWM generation, encoder decoding, and front-panel display multiplexing. The CMOS EEPROM technology is immune to soft errors and supports industrial temperature grades when selected appropriately. The 34 user I/Os drive up to 7-segment displays, keypads, or stepper-motor drivers directly via external transistors. The PLCC-44 socket enables rapid factory firmware updates across product variants.

🖥️

Legacy System Upgrade and Bridging

The EPM3064ALC44-4 is widely deployed as a drop-in upgrade path for end-of-life discrete-logic boards. Its 64 macrocells and 5V-tolerant I/Os let it emulate obsolete 74LS, 74F, and 74AS TTL functions, replacing discontinued bus-interface ASICs without redesigning the PCB. The 44-pin PLCC socket is industry-standard across thousands of legacy industrial PCs, telecom backplanes, and avionics modules, so the same CPLD can be retrofitted to multiple board generations.

📺

Prototype and Educational Development

Universities and design labs use the EPM3064ALC44-4 (in PLCC-44 socket-friendly form) for teaching digital design, because it can be repeatedly programmed via JTAG, supports Quartus II/MAX+PLUS II development flows, and survives student handling. The 64 macrocells are large enough for full 4-bit or 8-bit processor demonstrations, simple UART controllers, or VGA-timing generators. The wide 2.5-5.0V I/O range lets students interface the CPLD directly to a broad mix of sensors and discrete logic on a breadboard.

What is the EPM3064ALC44-4?
The EPM3064ALC44-4 is a 64-macrocell, 34-I/O CMOS EEPROM-based CPLD from the Altera MAX 3000A family, with a 4.5 ns pin-to-pin delay in a 44-pin PLCC (J-Lead) package. It supports 3.3-V in-system programmability via the IEEE 1149.1 JTAG interface and is intended for glue-logic, address decoding, and bus-interface bridging in commercial-grade designs.
How many macrocells and I/O pins does the EPM3064ALC44-4 have?
According to the manufacturer datasheet, the EPM3064ALC44-4 provides 64 macrocells organized in 2 Logic Array Blocks (LABs), with 34 usable user I/O pins. The remaining pins on the 44-pin PLCC package are dedicated to power (VCCINT, VCCIO, GND) and the four JTAG signals TDI, TDO, TMS, and TCK.
What is the propagation delay of EPM3064ALC44-4?
The EPM3064ALC44-4 has a worst-case pin-to-pin propagation delay (tPD) of 4.5 ns, as encoded by the speed-grade suffix '-4' in the part number. This makes it the fastest speed grade offered in the EPM3064A PLCC-44 family; slower grades (-7 and -10) trade speed for lower cost in non-critical paths.
Does the EPM3064ALC44-4 support in-system programming (ISP)?
Yes, the EPM3064ALC44-4 supports 3.3-V in-system programmability through the built-in IEEE Std. 1149.1 JTAG interface. Designers can reconfigure the device on a populated PCB via the TDI, TDO, TMS, and TCK pins using Altera Quartus II or legacy MAX+PLUS II software and a ByteBlaster or USB-Blaster download cable.
What is the difference between EPM3064ALC44-4 and EPM3064ALC44-10?
Both parts share the same PLCC-44 footprint, 64 macrocells, and 34 I/O pins; they differ only in speed grade. The EPM3064ALC44-4 has a 4.5 ns tPD while the EPM3064ALC44-10 has a 10 ns tPD, making the '-4' roughly 2x faster and the preferred choice for high-speed glue-logic where setup/hold margins are tight.
Where to buy EPM3064ALC44-4 online?
As of 2026-09-12, the EPM3064ALC44-4 can be sourced through distributors listed on DigiKey (544-1973-ND), Mouser, Heisener, Vyrian, and Ariat-Tech. Because Altera has marked this part obsolete or NRND in favor of newer MAX II/MAX V families, expect limited stock, longer lead times, and price premiums compared to active CPLDs.
What is the price of EPM3064ALC44-4?
As of 2026-09-12, the EPM3064ALC44-4 is listed at approximately USD 6.32 for single-piece purchases (per Heisener stock data); quantity pricing on DigiKey and other authorized distributors typically ranges from USD 4-5 at 1000-piece breaks. Because the part is mature/obsolete, prices fluctuate with remaining distributor inventory.
What is the lead time for EPM3064ALC44-4?
As of 2026-09-12, Heisener reports 'Lead Time To Be Confirmed' with estimated delivery windows of Apr 11 - Apr 16 for expedited shipping. Lead times for legacy Altera MAX 3000A parts vary widely by distributor and stock depth; sourcing from franchised distributors such as DigiKey or Mouser typically gives the most reliable schedules.
Is the EPM3064ALC44-4 still in stock?
As of 2026-09-12, Heisener lists approximately in stock for the EPM3064ALC44-4. Because Altera has transitioned many MAX 3000A parts to obsolete/NRND status, stock levels at major distributors have been declining for several years, so buyers should consider second-source or migration options for new designs.
What is the best drop-in replacement for EPM3064ALC44-4?
The closest drop-in replacements for the EPM3064ALC44-4 in the same 44-pin PLCC package are the speed-grade variants EPM3064ALC44-7 (7.5 ns tPD) and EPM3064ALC44-10 (10 ns tPD) from the same Altera MAX 3000A family. For new designs with relaxed footprint constraints, the MAX II EPM240 and MAX V 5M40ZE64 in modern QFP packages offer more logic at lower cost but require PCB rework.
EPM3064ALC44-4 vs EPM3064ALC44-10N - which is better for industrial control?
The EPM3064ALC44-4 and EPM3064ALC44-10N both deliver 64 macrocells in PLCC-44, but the '-4' is faster at 4.5 ns tPD versus 10 ns for the '-10N', and the 'N' suffix typically denotes an updated revision or Pb-free reflow-compatible finish. For industrial control where 10 ns timing is acceptable and a lead-free finish is required, the '-10N' is the better choice; for tight bus-timing budgets, the '-4' wins.
When should I choose EPM3064ALC44-4 over EPM3032ATC44-10?
Choose the EPM3064ALC44-4 when you need 64 macrocells (twice the density of the EPM3032A's 32 macrocells) and a 4.5 ns tPD for high-speed paths. Choose the EPM3032ATC44-10 when your design only needs ~32 macrocells and 10 ns timing and you want the lower unit cost of the smaller MAX 3000A device in the same PLCC-44 footprint.
Where to download the EPM3064ALC44-4 datasheet PDF?
The EPM3064ALC44-4 datasheet (MAX 3000A Programmable Logic Device Family datasheet, Altera Corporation) can be downloaded from datasheet aggregators such as Alldatasheet.com (URL above) or from Altera/Intel's archived documentation. The document describes architecture, DC/AC characteristics, JTAG programming, and 44-pin PLCC package information.
Where to find the EPM3064ALC44-4 pinout?
The 44-pin PLCC pinout for the EPM3064ALC44-4 is published in the MAX 3000A datasheet (Altera Corporation). Pin 1 is located at the top of the package near the dot/index mark, with pins numbered counter-clockwise; the device uses standard JTAG pins (TDI, TDO, TMS, TCK), multiple VCCINT/VCCIO/GND pins, and 34 user I/O pins labeled IO0-IO33.
What software programs the EPM3064ALC44-4?
The EPM3064ALC44-4 is programmed with legacy Altera design software, including MAX+PLUS II (for older flows) and Altera Quartus II (later versions supporting MAX 3000A). Designs are compiled to a JEDEC file and downloaded via JTAG using a ByteBlasterMV, USB-Blaster, or compatible cable from a PC parallel/USB port.

انتخاب کی گائیڈ

Choose the EPM3064ALC44-4 when you need 64 macrocells of EEPROM-based glue logic with the fastest 4.5 ns tPD available in the 44-pin PLCC MAX 3000A family, especially in legacy industrial boards that require direct 5V I/O interfacing. Choose the EPM3064ALC44-10N if you can accept 10 ns timing and want a Pb-free finish for modern lead-free reflow lines. Choose the EPM3032ATC44-10N when 32 macrocells suffice and you want the lowest unit cost in the same PLCC-44 footprint. For new designs, migrate to MAX II (EPM240) or MAX V (5M40ZE64) CPLDs in modern TQFP/QFN packages - they offer more logic, lower power, and active lifecycle status, though they require PCB rework.

ڈیزائن نوٹس

The EPM3064ALC44-4 uses separate VCCINT (3.3V core) and VCCIO (2.5V/3.3V/5.0V I/O) supplies. Place 0.1 uF ceramic decoupling capacitors as close as possible to every VCCINT and VCCIO pin, with one bulk 10-47 uF tantalum or aluminum polymer cap on each supply rail. This decouples high-frequency switching transients from the EEPROM programming charge pumps and prevents inadvertent JTAG ISP failures during in-field firmware updates.

JTAG ISP requires careful PCB layout: keep the TDI, TDO, TMS, TCK traces short (<50 mm), add 10 kohm pull-ups on TDI/TMS/TCK to VCCIO, and isolate the JTAG chain from noisy switching signals. The PLCC-44 socket allows easy field replacement, but ensure the socket is a low-profile type with reliable J-lead contacts - Mill-Max 110-44-632-41-003 or equivalent 44-pin PLCC sockets are recommended for production environments.

Estimated: the EPM3064ALC44-4 has 64 macrocells but the Quartus II / MAX+PLUS II fitter may report only 52-56 usable macrocells after JTAG TAP and ISP overhead are reserved. Always reserve 4-8 macrocells for unused I/O tie-offs and global signal buffers. Do not exceed the maximum I/O current rating (per-pin sink/source) specified in the datasheet - exceeding this will trigger EEPROM programming failures and unreliable ISP cycles.
