Typical Applications
EPM3064ATI100-10N is suitable for 6 applications: Industrial Bus and Address Decoding, PCI Interface Glue Logic, Embedded SBC Glue Logic Replacement, 3.3 V to 5 V Level Translation Bridge, State-Machine and Timer Replacement, Prototyping and Field Upgrade via JTAG ISP.
Industrial Bus and Address Decoding
The EPM3064ATI100-10N is well matched to bus-address decoding in industrial controllers, where its 64 macrocells can implement 30+ chip-select decoders, address comparators, and wait-state generators in a single device. Its 10 ns pin-to-pin delay in the -10 speed grade keeps well within the ISA/PCI bus budgets, while MultiVolt I/O lets the CPLD sit between a 3.3 V microcontroller and legacy 5 V peripherals on the same backplane without level-shifters. JTAG ISP means field updates to decode maps can be done over the same test access port used for board bring-up.
Recommended
PCI Interface Glue Logic
The EPM3064ATI100-10N is explicitly PCI-SIG Revision 2.2 compliant at -4/-5/-6/-7/-10 speed grades, making it suitable for implementing PCI target-state machines, configuration-space registers, and bus-arbitration glue on legacy add-in cards. The 66 user I/O cover the full 32-bit PCI bus plus side-band signals, while the deterministic 10 ns tPD in the -10 grade simplifies worst-case timing closure. MultiVolt I/O pads are 5 V tolerant, eliminating the need for external PCI clamp diodes when interfacing to 5 V mainboards.
Recommended
Embedded SBC Glue Logic Replacement
PC/104, VME, and custom embedded SBC designs often need to consolidate discrete 74-series logic (74LS138/245/374, PAL/GAL glue) into a single low-power, reprogrammable device. The EPM3064ATI100-10N fits this role: 64 macrocells replace 4-6 discrete SSI/MSI packages, EEPROM retention means instant-on with no boot PROM, and the 100-pin TQFP provides ample I/O for 16- and 32-bit data buses plus address and control lines. Industrial -40 C to +85 C temperature range covers outdoor and factory-floor deployments.
Recommended
3.3 V to 5 V Level Translation Bridge
The EPM3064ATI100-10N's MultiVolt I/O supports 2.5 V / 3.3 V / 5 V mixed-voltage signaling on a per-pin basis, making it a flexible bidirectional level shifter for legacy boards that need to add a modern 3.3 V ASIC or FPGA next to 5 V peripherals. With 66 I/O pins available, a single device can handle 16-32 channels of translation plus side-band control logic (bus turnaround, direction control). The 10 ns propagation delay in the -10 grade adds only one gate delay to the timing budget, which is acceptable for most peripheral buses.
Recommended
State-Machine and Timer Replacement
Replacing discrete 74LS/HC state machines, one-shots, and counters with a single EPM3064ATI100-10N reduces PCB area and improves reliability on long-life industrial designs. The 64 macrocells, each with a dedicated flip-flop, comfortably implement 8-12 independent state machines with up to 16 states each, plus supporting counters and timers. Deterministic timing means no metastability surprises in safety-critical interlocks, and the EEPROM non-volatility keeps the design alive across power cycles without reconfiguration.
Recommended
Prototyping and Field Upgrade via JTAG ISP
The built-in IEEE 1149.1 JTAG port on the EPM3064ATI100-10N enables in-system programming from a ByteBlasterMV or USB-Blaster cable without removing the device from the board - critical for prototypes and field-deployed equipment that needs occasional logic revisions. The same JTAG chain can be shared with other JTAG-compliant devices (microcontrollers, FPGAs, boundary-scan parts), and the Quartus II / MAX+PLUS II toolchains support incremental recompile-to-bitstream in under a minute for designs that fit in 64 macrocells.

Key Differentiators
- Industrial temperature range with leaded finish (vs EPM3064ATC100-10N)
- Same TQFP-100 footprint as faster speed grades (vs EPM3064ATC100-4N)
- Pin-compatible migration path to MAX II (vs EPM240T100C5N (MAX II))
Design Notes
Place the EPM3064ATI100-10N's 3.3 V VCCINT and 3.3 V/2.5 V/5 V VCCIO decoupling capacitors as close to each package pin pair as possible - one 0.1 uF X7R ceramic per VCC pin plus a single 10 uF bulk tantalum/ceramic at the board edge. The TQFP-100 package's exposed lead frame also benefits from a continuous ground plane on the layer directly beneath the IC, which both reduces ground bounce and improves thermal dissipation for hot-swap industrial backplanes.
The MultiVolt I/O pads are 5 V tolerant when VCCIO is set to 3.3 V, but they require careful series-resistor or source-termination design when driving long PCB traces. For clock outputs (e.g., TCK from the JTAG chain), keep the trace under 50 mm and add a 33 ohm series resistor at the driver to dampen reflections. Inputs from 5 V peripherals should be AC-coupled or diode-clamped if hot-plug events are possible.
When migrating from the EPM3064ATI100-10N to a MAX II device (e.g., EPM240T100C5N), do not assume JTAG chain order is preserved: MAX II uses a different BSDL file and TAP instruction set. Always re-validate the JTAG chain with the new BSDL and re-generate the Quartus Prime programming file before board bring-up. Also note that the MAX 3000A "N" suffix indicates lead-free processing while the absence of "N" indicates leaded finish - confirm before RoHS-critical designs.
Estimated: at the maximum I/O toggle rate of ~100 MHz on 32 of 66 outputs into 50 pF loads, the EPM3064ATI100-10N dissipates approximately 0.5-1.0 W. The TQFP-100 package's theta_JA of approximately 50 C/W (estimated, no datasheet figure available) yields a 25-50 C junction-temperature rise over ambient, well within the 125 C maximum junction spec. For sealed industrial enclosures with no airflow, derate toggle activity to 50% and consider a copper-pour heatsink on the top layer.
