Typical Applications
EPM3032ATC44-10NAA is suitable for 6 applications: Address Decoding and Glue Logic, Mixed-Voltage Logic-Level Translation, State Machine and Control Logic, I/O Expansion and Bus Interfacing, Legacy Telecom Linecard Glue, Industrial Control and Instrumentation.
Address Decoding and Glue Logic
The EPM3032ATC44-10NAA's 32 macrocells across 2 LABs and 34 user I/O pins make it well suited for address decoding, chip-select generation, and bus-interface glue logic in 8/16/32-bit microcontroller and microprocessor systems. With a 10 ns tpd the part can decode address lines and generate peripheral strobes within one clock cycle at 50 MHz. MultiVolt 5.0V/3.3V/2.5V I/O lets the CPLD bridge between a 5.0V legacy MCU bus and a 3.3V peripheral without external translators, saving both board area and BOM cost. Place the part near the address latch and route all decoded signals through it. Compared with discrete 74HC/74F logic, one EPM3032ATC44-10NAA replaces up to a dozen SSI/MSI packages.
Recommended
Mixed-Voltage Logic-Level Translation
The MultiVolt I/O on the EPM3032ATC44-10NAA supports simultaneous 5.0V, 3.3V, and 2.5V logic interfaces on the same device by grouping pins into VCCIO banks. This makes it an excellent bidirectional voltage translator between legacy 5.0V peripherals and modern 3.3V or 2.5V ASICs, FPGAs, or processors. The 34 I/O pins can be partitioned into independent banks, each powered from its own VCCIO rail. Non-volatile EEPROM storage means translation logic remains in place after power cycling without reloading firmware. Use this for production-line replacement of discrete resistor-divider or FET-based level-shift circuits to reduce BOM count and improve signal integrity.
Recommended
State Machine and Control Logic
Each EPM3032ATC44-10NAA macrocell contains a programmable AND-OR array with a configurable D flip-flop and selectable register/bypass modes, making the device an efficient platform for implementing multi-state control machines. With 32 macrocells, the part can host 10-15 states with multiple output decoded actions per state. The 10 ns tpd and global clock/clear networks support deterministic synchronous state transitions. Common uses include motor-control sequencers, traffic-light controllers, vending-machine state graphs, and industrial timer/counter logic. The non-volatile EEPROM cell also stores the state machine definition permanently, so power-cycling does not require reconfiguration.
Recommended
I/O Expansion and Bus Interfacing
Microcontrollers with too few GPIOs can use the EPM3032ATC44-10NAA as an I/O expander, exposing up to 34 additional general-purpose I/O pins controlled over SPI or parallel from the host MCU. Each pin supports 5.0V/3.3V/2.5V signaling, so the expander can drive or receive logic levels the host MCU cannot tolerate directly. The non-volatile configuration also enables standalone bus-interface bridges (for example, parallel-to-parallel with timing adjustments or 8-bit to 16-bit multiplexing) without any host processor intervention. Engineers use this to recover from MCU pin shortages or to add legacy-parallel peripherals to modern SPI-only processors.
Recommended
Legacy Telecom Linecard Glue
Telecom linecard designs historically used MAX 3000A parts like the EPM3032ATC44-10NAA for alarm monitoring, switch-fabric control, and clock-distribution glue logic. The 3.3V core, MultiVolt 5.0V/3.3V I/O, and hot-socketing support let linecards be inserted into a live backplane without damaging the CPLD or backplane drivers. The IEEE Std. 1149.1 JTAG interface enables board-level boundary-scan test of the surrounding circuitry, critical for high-pin-count telecom assemblies. For modern designs requiring long-term support, migrate to MAX II EPM240 or MAX V devices, which offer higher density and active product lifecycle.
Recommended
Industrial Control and Instrumentation
In industrial control panels and instrumentation equipment, the EPM3032ATC44-10NAA consolidates random SSI/MSI glue logic into a single reprogrammable device, simplifying manufacturing and enabling late-stage design changes via JTAG. The 34 MultiVolt I/O pins can interface directly to 24V-to-5V signal-conditioning circuits, opto-isolated inputs, and 3.3V sensor buses from the same chip. Non-volatile EEPROM storage holds the configuration across power cycles and brown-outs. Designers use this part to implement safety-interlock logic, encoder/decoder pairs, pulse-width modulation timing, and front-panel multiplexing. Although marked obsolete, it remains in service in many legacy industrial machines and continues to be specified for spare-part replacements.

Key Differentiators
- Identical silicon die across drop-in family variants (vs EPM3032ATC44-10N)
- Industrial-temperature drop-in option available (vs EPM3032ALI44-10N)
- MultiVolt 5.0V/3.3V/2.5V I/O eliminates external translators (vs Discrete 74-series logic translators)
Design Notes
Decouple the EPM3032ATC44-10NAA following the MAX 3000A family datasheet guideline: place one 0.1 uF ceramic capacitor between each VCCINT pin and the nearest GND, plus a single 10-100 uF bulk capacitor on the 3.3V core rail near the package. Each VCCIO bank should also have its own 0.1 uF decoupling capacitor. Keep all decoupling traces short (under 5 mm) to minimize parasitic inductance at the CPLD's switching edges.
When using the EPM3032ATC44-10NAA's MultiVolt I/O to translate between 5.0V and 3.3V logic, group all 5.0V peripherals on one VCCIO bank and all 3.3V peripherals on a different bank. Mixing voltages within a single bank risks contention or forward-biasing the I/O ESD diodes. Series resistors (22-33 ohm) on high-speed outputs can help dampen ringing when driving long PCB traces.
Estimated: This part is marked obsolete by Intel/Altera, so new orders depend on remaining distributor and broker stock. Verify lead time and authenticity with multiple authorized sources before committing to production. Plan a migration path to MAX II (EPM240) or MAX V devices for new designs, since the JTAG chain, Quartus compilation database, and pinout will all need updating. Do not assume long-term availability of any EPM3032ATC44- variant.
Route JTAG signals TCK, TMS, TDI, TDO as a daisy chain through all JTAG devices on the board; do not stub these lines. Place pull-up resistors on TMS and TDI (per IEEE 1149.1) and a pull-up on TCK if the boundary-scan controller does not drive it continuously. Keep JTAG traces away from high-current switching signals to prevent programming failures during in-system programming.
Compliance Information
The Altera EPM3032ATC44-10NAA predates RoHS enforcement timelines in the original datasheet family; RoHS/REACH/lead-free status is not explicitly stated in the verified data and is marked unknown. This part is not qualified to AEC-Q100 because it is a commercial-grade programmable logic device, not an automotive-grade IC.
