Typical Applications
EPM3032ATC44-10N is suitable for 6 applications: Address Decoding and Chip-Select Generation, Power Sequencing and Reset Controller, Industrial Control and State-Machine Logic, Bus Interface Bridging and Voltage Translation, Peripheral Chip-Select Generator for Microprocessor Boards, LED Display and Multiplexed Panel Driver.
Address Decoding and Chip-Select Generation
The EPM3032ATC44-10N's 32 macrocells and 10 ns pin-to-pin delay make it well suited for address-decoding and chip-select generation on 8/16/32-bit microprocessor buses. With 34 user I/O pins, the device can decode up to 17 address lines plus generate bank-enable and read/write strobes in a single deterministic glue-logic block, replacing 3-5 discrete 74LS/74HC TTL packages. Its 138.9 MHz fCNT ensures clean timing on 50 MHz local buses, and the 3.3 V VCCINT lets it sit directly on modern ARM/x86 processor buses without level shifting.
Recommended
Power Sequencing and Reset Controller
The EPM3032ATC44-10N is widely used as a power-up sequencing and reset controller in multi-rail embedded systems. Its EEPROM-based instant-on configuration means the device is fully operational within microseconds of VCCINT ramp, earlier than the FPGA or ASIC it controls, allowing deterministic reset-stretch and power-good cascade signals. The MultiVolt I/O pins (5.0/3.3/2.5 V) drive enable lines to LDOs and DC-DC converters of different rails from a single device, and 34 I/Os handle up to 8 sequenced rails with margin. Its 10 ns delay is fast enough for sub-millisecond cascade sequencing.
Recommended
Industrial Control and State-Machine Logic
The 32 macrocells in the EPM3032ATC44-10N are sufficient for 4-6 state-machine controllers commonly used in industrial automation, motor-control front-ends, and sensor-multiplexing front-ends. With 10 ns deterministic pin-to-pin timing, the device produces glitch-free outputs even under heavy EMI, outperforming microcontrollers for hard-real-time sub-microsecond control loops. The 44-pin TQFP is small enough for compact PLC and sensor-hub PCBs, and the JTAG ISP allows in-field firmware updates through the same connector used for production programming.
Recommended
Bus Interface Bridging and Voltage Translation
The EPM3032ATC44-10N's MultiVolt I/O makes it a natural bus bridge between 5 V legacy peripherals and 3.3 V modern processors, replacing dedicated level shifters with programmable logic that can also perform width conversion, parity, or byte-swapping in the same device. Its 34 user I/Os accommodate a typical 8-bit data bus plus 8-bit address plus 4 control signals in a single chip, and the 10 ns tPD keeps throughput compatible with 8 MHz asynchronous peripheral buses. The JTAG ISP allows late-stage pinout changes during prototyping without board rework.
Recommended
Peripheral Chip-Select Generator for Microprocessor Boards
On VME, PC/104, and legacy PCI add-in cards, the EPM3032ATC44-10N serves as a single-chip chip-select generator, decoding upper address lines into individual CS lines for SRAM, Flash, UARTs, and timers. With 34 user I/Os the device can produce 12-16 individual chip-selects, and the 10 ns deterministic delay ensures address-to-CS skew remains under one clock cycle at 33 MHz. The EEPROM-based configuration eliminates the boot-device cost and complexity of an FPGA, making the part a cost-effective fit for low-to-medium complexity microprocessor peripherals.
Recommended
LED Display and Multiplexed Panel Driver
The EPM3032ATC44-10N is often deployed as a row/column driver controller for multiplexed LED matrix panels and seven-segment displays in industrial HMIs and signage. Its 34 user I/Os can drive up to a 4-by-8 multiplexed matrix directly, and the 10 ns tPD allows refresh rates above 1 kHz for flicker-free display. The open-drain output option on every I/O pin, mentioned in the Altera datasheet, is particularly valuable for wired-OR shared row/column lines. EEPROM-based instant-on ensures the display comes up correctly without a separate boot PROM.

Key Differentiators
- Faster speed grade as pin-compatible upgrade option (vs EPM3032ATC44-7N)
- Industry-standard 32-macrocell density with broader upgrade path (vs EPM3064ATC44-10N)
- Industrial temperature variant available in same package (vs EPM3032ALI44-10N)
Design Notes
The EPM3032ATC44-10N requires a clean 3.3 V supply on VCCINT (pins 43, 44) plus a MultiVolt VCCIO on pin 42 (5.0/3.3/2.5 V). Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VCCINT pin and a 10 uF bulk tantalum or ceramic capacitor on the VCCIO rail. Because EEPROM-based CPLDs have negligible inrush current during configuration, inrush-limit resistors are not required, but the VCCINT ramp time should remain between 1 ms and 100 ms per the Altera MAX 3000A datasheet to guarantee proper configuration.
Route the JTAG chain (TCK pin 17, TMS pin 16, TDI pin 15, TDO pin 37) as a short daisy-chain with 33 ohm series termination near the CPLD when the cable length exceeds 100 mm. Per the IEEE 1149.1 specification referenced in the Altera datasheet, keep the JTAG traces clear of switching signals and add a 10 kohm pull-up on TMS and TDI. The four GND pins (9, 22, 30, 38) should all be connected to a low-impedance ground plane to minimize ground bounce on high-speed outputs.
MultiVolt I/O pins can drive 5.0 V signals when VCCIO is set to 3.3 V but cannot drive beyond VCCIO + 0.3 V. For inputs above VCCIO, use an external series resistor of 100-470 ohm to limit current into the I/O cell per the MAX 3000A datasheet absolute maximum ratings. Open-drain outputs (selectable per I/O per the datasheet) require external pull-up resistors sized for the desired rise time: 4.7 kohm for 1 MHz, 1 kohm for 10 MHz switching.
Do not assume the EPM3032ATC44-10N is in active production - the part is being phased out under Intel PSG's 8-inch eutectic/High-Pb wafer bump discontinuation. Before committing to a long-life design, register with Intel PSG and qualify a pin-compatible replacement such as EPM3032ATC44-7N (faster, same family) or migrate to the MAX II / MAX V CPLD family. Do not substitute the 44-pin TQFP with a 44-pin PLCC variant of the same family; PLCC and TQFP footprints are not drop-in compatible and require PCB rework.
Compliance Information
