Typical Applications
EPM3064ALC44-10 is suitable for 7 applications: Industrial Control and PLC Logic, Address Decoding and Bus Interface Bridging, Telecom Backplane Glue Logic, I/O Expansion for ASICs and Microcontrollers, Legacy Peripheral Replacement (74-series Glue Logic), Aerospace and Defense Legacy Avionics, Test and Measurement Equipment.
Industrial Control and PLC Logic
The EPM3064ALC44-10 fits industrial control boards because its 64 macrocells deliver ample capacity for state-machine based PLC sequencing, encoder decoding, and PWM generation, while its 10ns pin-to-pin delay supports deterministic real-time response at modest clock rates. Its 3.3V operation and industrial temperature variant (EPM3064ALI44-10) suit 24V-derived control rails. The PLCC socket footprint simplifies field replacement in legacy PLC modules and motor drives, and the JTAG ISP enables in-circuit firmware updates during commissioning. Compared to microcontrollers, the CPLD offers guaranteed timing for parallel logic tasks without RTOS overhead.
Recommended
Address Decoding and Bus Interface Bridging
The EPM3064ALC44-10 is a classic choice for address decoding in 8/16/32-bit microprocessor systems because its deterministic 10ns tPD matches the timing budget of ISA, PC/104, and legacy 68k buses. With 34 user I/O pins it can decode large address windows for memory and peripheral chip-select generation without external 74LS138 decoders. The MultiVolt I/O interface allows direct connection to 5.0V microprocessors while operating from a 3.3V core supply, eliminating level shifters. Compared to discrete TTL logic, one CPLD replaces 5-10 decoder chips, reducing board area and BOM cost in legacy system designs.
Recommended
Telecom Backplane Glue Logic
Telecom backplane designs use the EPM3064ALC44-10 for low-speed serial protocol bridging, frame synchronization, and clock distribution where its 192.3 MHz counter frequency exceeds the 50 MHz backplane data rate. The EEPROM-based configuration stores the logic image permanently, making it immune to power-cycle loss unlike SRAM-based FPGAs. Its low 3.3V supply current suits densely-populated line cards with strict thermal budgets, and the JTAG ISP chain allows board-level programming during factory test. Compared to small FPGAs, the CPLD provides faster wake-up and lower cost per logic function in fixed-function bridging tasks.
Recommended
I/O Expansion for ASICs and Microcontrollers
Designers use the EPM3064ALC44-10 to expand the limited I/O count of microcontrollers and ASICs by off-loading bit-banging tasks such as LCD driving, keypad scanning, and parallel port emulation. The CPLD's 34 user I/O pins can be configured as inputs, outputs, or bidirectional under software control, and the 10ns tPD handles scan rates well above typical 100kHz peripheral speeds. Its 3.3V core with 5.0V-tolerant I/O allows direct interface to legacy peripherals without voltage translation. Compared to GPIO expanders over I2C/SPI, a CPLD offers parallel access with deterministic latency.
Recommended
Legacy Peripheral Replacement (74-series Glue Logic)
The EPM3064ALC44-10 consolidates dozens of 74LS/HC/ACT series TTL gates, latches, and muxes into a single chip, replacing up to 10-15 discrete packages per design. Its 64 macrocells can implement complex glue logic functions like addressable latches, priority encoders, and bus arbiters that would otherwise require multiple cascaded TTL devices. The 44-PLCC package with J-Lead socket compatibility allows direct board-level integration into legacy through-hole designs. Compared to discrete TTL, the CPLD reduces power consumption, improves noise margin, and simplifies BOM management.
Recommended
Aerospace and Defense Legacy Avionics
The EPM3064ALC44-10 serves in legacy avionics where its MIL-spec compatible industrial temperature variant (EPM3064ALI44-10) operates from -40Β°C to +85Β°C with deterministic timing for cockpit display drivers and flight control I/O. The EEPROM-based configuration provides radiation-tolerant single-event-upset (SEU) immunity compared to SRAM FPGAs, though SEU-hardened FPGAs are now preferred for new designs. The 44-PLCC socket allows easy replacement during maintenance cycles on legacy platforms. Compared to ASIC alternatives, the programmable nature enables late-stage design changes without respinning silicon masks.
Recommended
Test and Measurement Equipment
Test equipment manufacturers deploy the EPM3064ALC44-10 for custom signal conditioning, trigger logic, and timing generation in bench-top instruments where its 10ns resolution enables precise pulse generation and edge alignment. The CPLD's deterministic timing eliminates jitter from software interrupt latency that plagues microcontroller-based designs. Its 3.3V core with MultiVolt I/O allows direct interface to 5V logic analyzers and oscilloscope trigger circuits. The 44-PLCC package supports both socketed prototypes and SMT production builds, and JTAG ISP enables factory calibration during assembly.

Key Differentiators
- PLCC socket compatibility with field-replaceable speed grades (vs EPM3064ALC44-7)
- Same-die industrial temperature variant for harsh environments (vs EPM3064ALI44-10)
- Lead-free RoHS-compliant variant in same footprint (vs EPM3064ALC44-10N)
Design Notes
The EPM3064ALC44-10 requires a stable 3.3V VCCINT supply with a tolerance of +/- 5% per the MAX 3000A datasheet. Place a 10uF tantalum bulk capacitor near the PLCC socket VCC pin (43) plus a 0.1uF ceramic decoupling capacitor within 5mm of the device. Add additional 0.01uF capacitors on each VCC/GND pair for high-frequency noise suppression. MultiVolt I/O pins operate at 2.5V/3.3V/5.0V independently from VCCINT, but each I/O bank should still share a clean reference rail. Estimated: based on MAX 3000A family DC characteristics and typical CMOS switching current of approximately 50mA during simultaneous switching of 16 I/O pins.
The 44-PLCC package with J-Lead (PLCC) footprint supports both socketed and soldered mounting. For production designs, use a through-hole PLCC socket (e.g. 3M 8400 series) to enable field replacement and upgrades to faster speed grades (-7 or -4). For SMT-only boards, reflow solder the PLCC directly with a peak temperature of 245C for 30 seconds per JEDEC J-STD-020. Keep JTAG trace lengths under 100mm to avoid signal integrity issues at TCK frequencies above 10MHz. Route TDI, TDO, TMS, TCK as a matched-length bus with 33 ohm series termination near the driver.
MultiVolt I/O pins can be configured per-pin as 2.5V, 3.3V, or 5.0V tolerant, but a common VREF for each I/O bank is required. The unused JTAG pins (TCK, TMS, TDI, TDO) should be pulled to known states: TCK pulled down through 10k ohm, TMS and TDI pulled up through 10k ohm, TDO left floating for ISP. Critical timing paths above 50 MHz require controlled-impedance routing (50 ohm microstrip) on outer PCB layers to minimize reflections. Use ground stitching vias every 25mm along JTAG and clock traces to reduce EMI and maintain signal integrity.
Do not confuse the EPM3064ALC44-10 (commercial, 0C to +70C) with the EPM3064ALI44-10 (industrial, -40C to +85C). The industrial variant costs approximately 30% more but is mandatory for outdoor or automotive deployments. The -10N suffix indicates full RoHS compliance versus the -10 (non-N) version; for new designs in EU markets, always select the -N variant. When migrating from the PLCC -10 to the TQFP -10, verify your PCB layout can accept the TQFP footprint (0.8mm pitch vs 1.27mm PLCC pitch) - these are NOT drop-in compatible despite identical functionality.
Compliance Information
RoHS compliant per L suffix in part number indicating lead-free terminal finish. The -10N variant provides full RoHS/REACH compliance. Not AEC-Q100 qualified (industrial temp variants exist for non-automotive harsh environments). Halogen-free and conflict minerals status not explicitly stated in verified web data.
