EPM3064ATI44-10NAE Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy. It provides deterministic timing, predictable I/O behavior, and zero-configuration power-up, which makes it ideal for bus decoding, address mapping, state-machine control, and interface bridging. The MAX 3000A architecture combines an EEPROM process with a classic MAX-style logic-array-block (LAB) interconnect, enabling in-system programmability (ISP) via JTAG and unlimited erase/program cycles.
Key features include 5.0 V tolerant I/O with VCCIO selectable between 2.5 V, 3.3 V, and 5.0 V; four dedicated inputs with JTAG boundary-scan support; a global Clear (GCLRn) and Output Enable (OE); per-macrocell flip-flops with selectable D, T, JK, or SR behavior; and Macros with both combinational and registered outputs. The device operates from a single 3.3 V core supply and supports MultiVolt I/O for mixed-voltage system integration.
Typical applications include legacy industrial control boards, glue logic between microcontrollers and peripherals, address decoding in 8-bit/16-bit embedded systems, motor-control state machines, and JTAG-programmable bus interface bridges. The instant-on non-volatile configuration eliminates boot delays and external configuration memory.
When designing, verify that target pin assignments are identical between source and destination designs, since MAX 3000A pinouts vary across density and package options. Always pull unused I/O pins to a defined logic level through the Quartus "Unused Pins" setting to minimize in-system current leakage.

Typical Applications
EPM3064ATI44-10NAE is suitable for 6 applications: Industrial Glue Logic and Bus Decoding, Motor Control State Machines, Legacy Interface Bridging (ISA/PCI/VME), JTAG-Programmable I/O Expansion, Power Supply Sequencing and Supervisory Logic, Test and Measurement Instrumentation Front-Ends.
Industrial Glue Logic and Bus Decoding
The EPM3064ATI44-10NAE's 64 macrocells and 34 user I/Os are ideal for address decoding, chip-select generation, and wait-state insertion in 8-bit and 16-bit embedded systems. With its 10 ns pin-to-pin delay and deterministic timing, this CPLD sits between a microcontroller and peripheral devices (SRAM, Flash, UART, ADC) to translate bus protocols without adding latency. The MAX 3000A non-volatile EEPROM configuration eliminates the boot delay of FPGAs and external configuration memory, allowing instant-on operation required by industrial PLCs and factory-automation controllers. The industrial temperature grade (-40 to +85 °C) ensures reliable operation in factory-floor environments.
Recommended
Motor Control State Machines
In brushless DC (BLDC) and stepper motor drives, the EPM3064ATI44-10NAE implements the commutation state machine, Hall-sensor decoding, and PWM blanking logic with deterministic 10 ns propagation delay. Its 34 I/Os comfortably accommodate Hall inputs (3), enable/fault lines, brake logic, and multi-phase PWM gating signals. The MultiVolt I/O (2.5 V, 3.3 V, 5.0 V) interfaces directly with 5 V gate drivers and 3.3 V microcontrollers, eliminating level-shifters. The non-volatile instant-on configuration ensures the motor controller starts in a known safe state on power-up, critical for safety-rated industrial drives and appliance controllers.
Recommended
Legacy Interface Bridging (ISA/PCI/VME)
The EPM3064ATI44-10NAE bridges legacy parallel buses (ISA, VME) to modern microcontrollers and FPGAs through custom glue logic, a task for which 64 macrocells and 5 V-tolerant I/O are well-suited. The JTAG-programmable logic lets engineers iterate on bus-translation logic without spinning a new PCB, dramatically reducing NRE costs for legacy-system retrofits. The 10 ns pin-to-pin delay is fast enough for ISA-bus timing (8 MHz) and basic VME handshakes. Military and aerospace legacy avionics often require MAX 3000A as a long-lifecycle, instant-on glue-logic solution that survives in harsh thermal environments.
Recommended
JTAG-Programmable I/O Expansion
For microcontroller-based systems that have exhausted their native I/O pins, the EPM3064ATI44-10NAE adds 34 programmable I/Os that can be reconfigured in-system via JTAG. Designers can implement shift registers, multiplexers, or PWM generators on the fly without changing firmware. The 34 I/Os split across the 44-pin TQFP make efficient use of board real estate, and the instant-on non-volatile configuration means I/O defaults are restored after power cycling. This is especially useful for prototype boards, breadboard instrumentation, and test fixtures where I/O requirements change frequently during development.
Recommended
Power Supply Sequencing and Supervisory Logic
In multi-rail power systems, the EPM3064ATI44-10NAE orchestrates power-up and power-down sequencing of DC-DC converters, LDOs, and ASIC supplies, replacing dozens of discrete logic gates and timing components. The 5 V-tolerant I/O can directly drive power-good (PG) lines and enable (EN) pins of switching regulators. The CPLD's deterministic 10 ns delay and 64 macrocells allow complex sequencing graphs to be implemented compactly, while JTAG programmability lets engineers adjust timing without board spins. Industrial-grade temperature range supports telecommunications and server-system power architectures.
Recommended
Test and Measurement Instrumentation Front-Ends
In bench-top instruments and ATE (Automatic Test Equipment) fixtures, the EPM3064ATI44-10NAE implements custom digital stimulus generation, pattern capture, and timing control with deterministic sub-15 ns edge placement. The 34 user I/Os allow direct interfacing with logic analyzers, oscilloscope triggers, and pattern-generator outputs. The non-volatile instant-on configuration ensures test fixtures boot into the correct test pattern without external memory, reducing rack space and BOM cost. The industrial temperature rating supports laboratory and field-test environments where commercial-grade parts would fail.

Design Notes
The EPM3064ATI44-10NAE requires two distinct supplies: VCCINT (3.3 V core) and VCCIO (2.5 V / 3.3 V / 5.0 V I/O). Decouple each VCC pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add a 10 µF bulk capacitor near the package. Per the MAX 3000A datasheet, all VCC pins must be connected even if their banks are unused, to prevent floating-supply latch-up. Tie unused VCCIO pins to the same rail as the active banks for simplicity. Power sequencing is not required; the device powers up into a defined state thanks to non-volatile EEPROM configuration.
Route JTAG signals (TCK, TMS, TDI, TDO) away from switching signals and clock traces to minimize noise coupling during in-system programming. Keep TCK trace length under 50 mm and add a 10 kΩ pull-up on TCK and TMS to VCCIO for reliable boundary-scan operation. For multi-board JTAG chains, place a 4.7 kΩ series resistor near each TDO pin to dampen reflections. The 44-pin TQFP has 0.8 mm pitch - use 0.15 mm/0.20 mm trace/space rules and consider microvia-in-pad for BGA escape routing if migrating to fine-pitch packages.
Estimated: configuration retention for the EEPROM-based MAX 3000A is rated for 20 years at 25 °C and 10 years at 85 °C. Do NOT assume the JTAG pins are 5 V-tolerant unless VCCIO = 5 V; if mixed-voltage rails are present, level-shift the JTAG lines externally. Always set the Quartus 'Unused Pins' option to 'As input tri-stated' or 'As output driving ground' to minimize quiescent current - floating inputs can draw several mA per pin. Verify that the JTAG chain order in your design matches the physical board order to avoid programming failures during production.
Place a continuous ground plane directly under the TQFP-44 package to provide low-impedance return paths for high-speed I/O transitions. Use 0.5 mm via stitching around the perimeter of the CPLD's keep-out area to suppress ground bounce. For designs with >16 simultaneous switching outputs, add 22 Ω series-termination resistors within 25 mm of the CPLD pins to dampen ringing on 50 Ω controlled-impedance traces. Pin 21 (GND) and pin 39 (GND) should both connect to the ground plane with at least two vias each for thermal and electrical conductivity.
