Typical Applications
EPM3032ALI44-10N is suitable for 6 applications: PCI Bus Arbiter and Decoder, Industrial Glue Logic and Address Decoder, Board-Level Voltage Interface Translation, Motor Control Front-End Logic, Legacy Embedded System Maintenance, JTAG-Based Board-Level Test Controller.
PCI Bus Arbiter and Decoder
The EPM3032ALI44-10N is well suited for PCI bus arbitration and address decoding in industrial embedded boards. With its 10 ns pin-to-pin delay and 227.3 MHz counter frequency, the part easily meets the PCI SIG Revision 2.2 timing requirements across speed grades -4 through -10. Its 32 macrocells handle typical 4-master arbiter state machines plus address-decoder glue logic, while the MultiVolt I/O (5.0/3.3/2.5 V) bridges legacy 5 V PCI slots with modern 3.3 V ASICs. Drop one onto a 44-PLCC socket and you have a deterministic, instant-on arbiter with no boot ROM required.
Recommended
Industrial Glue Logic and Address Decoder
In factory automation PLCs and process controllers, the EPM3032ALI44-10N is widely deployed as a deterministic glue-logic hub: chip-select decoding, wait-state generation, and bus-width adaptation. Its 32 macrocells handle the typical 8-to-16 chip-select address-decoder fan-out needed on a 16-bit microcontroller backplane, while the EEPROM-based non-volatile configuration means the device comes up in a known state at power-on - critical for safety-related control loops. The 3.3 V core plus 5 V-tolerant I/O eliminates level-shifters on mixed-rail legacy boards.
Recommended
Board-Level Voltage Interface Translation
Because the EPM3032ALI44-10N's MultiVolt I/O pins support 5.0 V, 3.3 V, and 2.5 V logic levels simultaneously, the device is an excellent bridge between modern low-voltage processors and legacy 5 V peripherals. Configure one bank of I/O as 5 V inputs from a legacy UART or parallel port, the other bank as 3.3 V outputs to a modern SoC, and you eliminate discrete level-shifter ICs entirely. The 32 macrocells easily absorb the protocol-conversion state machine, and JTAG ISP enables post-assembly board-level fixes.
Recommended
Motor Control Front-End Logic
Stepper and BLDC motor controllers rely on deterministic glue logic for direction latching, PWM synchronization, and fault interlocks. The EPM3032ALI44-10N's instant-on EEPROM configuration, 10 ns pin-to-pin delay, and 227.3 MHz counter frequency make it ideal for capturing Hall-sensor edges, generating quadrature outputs, and de-bouncing limit-switch inputs in industrial motor drives. Its industrial temperature rating suits factory-floor cabinets, and the 44-pin PLCC is socketable - field-replaceable without re-flow.
Recommended
Legacy Embedded System Maintenance
Long-lifecycle industrial equipment - SCADA RTUs, CNC controllers, medical instrument subassemblies - often requires exact drop-in replacements for obsolete or end-of-life parts. The EPM3032ALI44-10N remains in distribution specifically for these maintenance scenarios: its bitstream is identical to the lead-free EPM3032ALC44-10N, allowing technicians to swap without firmware rework. With 34 user I/O and 32 macrocells, it covers the typical 80% of legacy glue-logic designs without forcing a redesign.
Recommended
JTAG-Based Board-Level Test Controller
The EPM3032ALI44-10N's built-in IEEE 1149.1 JTAG interface allows it to act as a board-test controller, driving boundary-scan chains across multiple devices and aggregating pass/fail signals. Its 34 I/O can fan out to several JTAG sub-chains on a backplane, while 32 macrocells implement TAP-controller state machines and result-comparison logic. In production test, this configuration reduces fixture complexity and enables in-system test of dense digital boards where bed-of-nails access is impractical.

Key Differentiators
- Same-die drop-in compatibility with lead-free EPM3032ALC44-10N (vs EPM3032ALC44-10N)
- Higher density upgrade path in same 44-PLCC footprint (vs EPM3064ALC44-10)
- 5 V-tolerant core alternative for legacy mixed-rail designs (vs EPM7032AELC44-10N)
Design Notes
Estimated: the EPM3032ALI44-10N draws approximately 30-50 mA from VCCINT (3.3 V core) and 5-15 mA per I/O bank from VCCIO, depending on switching activity. Both rails must be bypassed with 0.1 uF ceramic capacitors placed within 5 mm of each supply pin. Add a 10 uF tantalum bulk capacitor on each rail at the board entry point. Use separate analog and digital ground returns if the board mixes analog and CPLD logic; star-ground the CPLD ground pins to a single low-impedance plane.
Route JTAG signals (TDI, TDO, TMS, TCK) as a daisy-chain with 10 kohm pull-ups on TMS and TCK to VCCIO. Keep JTAG traces under 150 mm total to avoid signal-integrity issues, and add a 4.7 kohm series resistor on TDO if the target board has long stubs. Reserve a 2x5 0.1-inch header for the Altera ByteBlaster or USB-Blaster programming cable; the part cannot be programmed without JTAG access. For socketed PLCC-44 designs, use a machined-pin IC socket to allow field replacement.
Do not confuse the EPM3032ALI44-10N (lead-bearing, RoHS non-compliant) with the EPM3032ALC44-10N (lead-free, RoHS-compliant) when ordering for European or RoHS-mandated production. The 'I' vs 'C' suffix reflects terminal finish only - both are pin-to-pin compatible. Also avoid mixing VCCIO voltages across I/O banks if your design bridges 5 V and 3.3 V logic; the MAX 3000A supports mixed-voltage banks but all I/O on a single bank must share one VCCIO rail.
Estimated: at 227.3 MHz internal counter frequency, output edge rates are 2-3 ns. For clock outputs routed more than 50 mm on FR-4, add 33 ohm series damping resistors to control overshoot and ringing. Keep high-speed I/O traces away from analog sections and use a continuous ground plane under the PLCC-44 footprint. For PCI applications, route the PCI clock signal as a 65 ohm impedance microstrip and length-match it to within 2 mm of any other PCI signal.
