Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EPM3064ATC100-4 is suitable for 6 applications: Legacy Bus Decode and Address Latching, PWM and Motor Control Timing Replacement, Industrial PLC I/O Expansion, Power Sequencing for Multi-Rail Systems, LED Display and Relay Scan Matrix Drivers, Legacy PCI-to-ISA Bridge Logic.
Legacy Bus Decode and Address Latching
The EPM3064ATC100-4 replaces discrete 74LS/74HC glue logic for ISA, PC/104, and embedded microcontroller bus decode with deterministic 4.5 ns tPD. Its 64 macro cells provide enough product terms to decode up to 32 address lines while generating chip-select, read/write strobes, and interrupt acknowledge signals simultaneously. The non-volatile EEPROM eliminates boot-up wait states, and MultiVolt I/O directly interfaces 5 V microcontrollers to 3.3 V peripherals without level shifters, simplifying legacy system retrofits in industrial controllers.
Recommended
PWM and Motor Control Timing Replacement
The EPM3064ATC100-4 generates precision PWM signals up to 227.3 MHz counter frequency for motor-control and SMPS applications, replacing multiple 555 timers and discrete counters. Its 64 macro cells allow simultaneous generation of 6+ phase-shifted PWM channels with dead-time insertion and fault handling. The 100-TQFP package supports industrial temperature ranges and the MultiVolt I/O directly drives 5 V gate drivers, making it a compact solution for three-phase BLDC and stepper drivers.
Recommended
Industrial PLC I/O Expansion
The EPM3064ATC100-4 expands discrete I/O on industrial PLCs by implementing shift-register interfaces, debouncers, and multiplexing logic in a single chip. Its 34 user I/O pins handle up to 32 optically-isolated inputs plus JTAG, while the 4.5 ns tPD supports deterministic scan rates above 1 MHz. The MAX 3000A architecture provides high-noise-immunity CMOS EEPROM cells suitable for industrial environments, and the JTAG ISP interface enables field firmware updates without powering down the line.
Recommended
Power Sequencing for Multi-Rail Systems
The EPM3064ATC100-4 generates programmable power-up/power-down sequencing for systems with 4-8 voltage rails using its deterministic EEPROM-backed macro cell logic. With 4.5 ns tPD the CPLD can enforce strict rail-to-rail timing budgets (typical 10-50 ms staggered delays) for FPGAs, ASICs, and DSPs that require specific enable sequences. The non-volatile configuration means sequencing starts instantly at power-on without processor intervention, critical for ASIL-rated automotive and medical systems.
Recommended
LED Display and Relay Scan Matrix Drivers
The EPM3064ATC100-4 drives large LED/relay multiplex matrices by implementing row/column scan logic and PWM dimming in hardware. Its 34 high-drive I/O pins handle up to 8x8 matrix scans at 100+ Hz refresh rates, while 64 macro cells provide per-channel brightness control and dead-time generation. The MultiVolt I/O directly interfaces 5 V LED drivers and 24 V relay coils via external transistors, making it ideal for industrial signage, instrumentation front panels, and elevator indicator arrays.
Recommended
Legacy PCI-to-ISA Bridge Logic
The EPM3064ATC100-4 implements PCI-to-ISA bridge glue logic for legacy embedded systems, replacing multiple PAL/GAL devices with a single deterministic CPLD. Its 4.5 ns tPD meets PCI 33 MHz timing budgets (15 ns cycle, 7 ns setup), and 64 macro cells are sufficient to decode PCI address/data/control signals while generating ISA bus cycles. The 100-TQFP package and 3.3 V core with 5 V-tolerant I/O simplify mixed-voltage system integration, particularly in industrial PCs and medical instruments.

Key Differentiators
- Fastest -4 speed grade in the MAX 3000A 100-TQFP family (vs EPM3064ATC100-10)
- Available as Pb-free variant (EPM3064ATC100-4N) with identical specs (vs EPM3064ATC100-4 (SnPb))
- Industrial temperature option via I-suffixed family member (vs EPM3064ATI100-10N)
Design Notes
Estimated: VCCINT must be regulated at 3.3 V +/- 5% with at least 100 mA peak capacity per EPM3064ATC100-4 device. VCCIO can be independently set to 2.5 V, 3.3 V, or 5.0 V to interface with mixed-voltage peripherals, but VCCINT must remain at 3.3 V. Place 0.1 uF decoupling caps on every VCCINT/VCCIO pin pair plus a single 10 uF bulk cap near the package. Power-up sequencing is not required between VCCINT and VCCIO - the MultiVolt I/O tolerates either rail coming up first per MAX 3000A datasheet.
The 100-TQFP package has 0.5 mm pitch and requires careful PCB layout. Route all JTAG signals (TCK, TMS, TDI, TDO) as a controlled-impedance group with 4.7 kohm pull-ups on TMS and TDI per Altera's ByteBlaster reference design. Keep JTAG traces away from switching signals; add a ground guard ring around the JTAG header. Allocate at least 4 layers (signal/ground/power/signal) for proper return paths and to maintain signal integrity on the 4.5 ns timing paths.
Do not confuse the EPM3064ATC100-4 (commercial temp, SnPb) with the EPM3064ATC100-4N (commercial temp, Pb-free) or EPM3064ATI100-10N (industrial temp, 10 ns grade) - they share the same package but different temperature ranges and finishes. Also avoid mixing speed grades (-4, -7, -10) when programming with Quartus II, as the fitter output will produce timing violations. Always configure unused I/O pins as outputs driving low (per MAX 3000A datasheet) to minimize power consumption and switching noise.
Compliance Information
RoHS/REACH compliance not explicitly stated in verified data; -4N and -10NA variants are Pb-free per their suffix designation. AEC-Q100 not applicable for legacy Altera CPLD line. Always request official manufacturer declarations for RoHS-restricted designs.
