Safe Operating Area (SOA) & Thermal Characteristics

Typical Applications
EPM3032ATC44-10 is suitable for 6 applications: Bus Address Decoding & Chip-Select Glue Logic, State-Machine & Sequential Control, Legacy SPLD Pin-Compatible Replacement, Power-Up Sequencing & Reset Management, JTAG Boundary-Scan Test Chain Controller, Industrial Embedded Control Boards.
Bus Address Decoding & Chip-Select Glue Logic
The EPM3032ATC44-10 is ideally suited for bus address-decoding and chip-select generation in 8051, ARM7, and MIPS-based embedded boards, where its 32 macrocells and 10 ns deterministic delay cleanly translate processor address-bus cycles into peripheral enables. With 34 user I/O pins, the device can generate chip-selects for up to a dozen peripherals in a single package, replacing multiple 74LS138/74HC138 decoders. The non-volatile EEPROM configuration means the decode map is active within the 10 ns tPD at power-up β critical for systems where the processor begins fetching boot code immediately after reset. The 3.3 V core with multiVolt I/O also allows direct interfacing with 5 V peripherals on legacy buses.
Recommended
State-Machine & Sequential Control
The EPM3032ATC44-10's macrocell flip-flops and product-term logic make it an efficient platform for implementing complex state machines, washing-machine controllers, and protocol sequencers. Each of the 32 macrocells provides a D flip-flop plus combinatorial logic, enabling 16-state to 32-state machines with deterministic 10 ns transitions that are independent of design placement β a property FPGAs cannot match. The JTAG ISP allows iterative state-machine debugging directly in-circuit. The 600-gate equivalent capacity fits typical 16-32 state FSMs with multiple output conditions, while the 34 I/O pins provide ample fan-out for actuator/indicator interfaces in industrial equipment.
Recommended
Legacy SPLD Pin-Compatible Replacement
The EPM3032ATC44-10 is widely deployed as a pin-compatible functional upgrade for legacy 22V10, 16V8, and 20V8 SPLDs in legacy industrial and military systems, where the existing PLCC-44 or DIP-20 footprints can accept a TQFP-44 with a socket adapter. The 32-macrocell capacity replaces the 22V10's 10 macrocells and offers 4 times more logic, plus a JTAG ISP interface that legacy SPLDs lack. The 10 ns tPD matches the 22V10-10 speed grade, preserving critical setup/hold timing in retrofit designs. Engineers can re-implement the legacy fuse-map logic in VHDL/Verilog and recompile without changing the PCB layout.
Recommended
Power-Up Sequencing & Reset Management
The EPM3032ATC44-10's EEPROM non-volatile configuration activates within microseconds of VCC reaching 3.0 V, making it suitable for power-up sequencing controllers in multi-rail systems. The device can monitor power-good inputs and stagger enable outputs to ASICs, FPGAs, and DC-DC converters with deterministic timing. The internal 227.3 MHz maximum frequency allows sequencing blocks to chain within nanoseconds of each other. The JTAG port additionally enables field re-programming of the sequencing order without board rework. The 0-70 Β°C commercial temperature range suits indoor and protected industrial enclosures.
Recommended
JTAG Boundary-Scan Test Chain Controller
The EPM3032ATC44-10's built-in IEEE 1149.1 JTAG interface allows it to participate as a TAP controller in board-level boundary-scan test chains, enabling manufacturing interconnect diagnostics on complex multi-layer PCBs. The 34 user I/O pins can be configured as boundary-scan cells to detect solder bridges and opens between CPLDs, microprocessors, and memory devices. The 10 ns tPD supports TCK frequencies up to the JTAG specification limit. The non-volatile EEPROM keeps the boundary-scan configuration persistent through power cycles and is re-programmable via JTAG for test pattern updates.
Recommended
Industrial Embedded Control Boards
The EPM3032ATC44-10 is a common logic hub on industrial PLC I/O boards, motor-control PCBs, and instrumentation front-ends, where its 10 ns deterministic delay drives encoder counters, PWM generators, and protection interlocks. The 3.3 V core reduces power dissipation to about half that of 5 V CPLDs, beneficial in densely populated 0-70 Β°C enclosures. The 44-TQFP footprint exposes enough I/O to interface with multiple ADC/DAC channels or stepper-motor drivers. Combined with a 3.3 V microcontroller, the EPM3032ATC44-10 offloads time-critical logic, freeing the MCU for higher-level tasks.

Key Differentiators
- Drop-in compatible with multiple MAX 3000A package variants for long-term supply continuity (vs EPM3032ATC44-10N)
- Industrial temperature range option in identical footprint (vs EPM3032ALI44-10N)
- Built-in IEEE 1149.1 JTAG for ISP and boundary-scan test (vs Legacy 22V10 SPLD)
Design Notes
Estimated: at VCC=3.3 V, all 34 I/O toggling at 50 MHz with 50% activity and 30 pF load per pin, dynamic current per I/O is approximately CVf = 30pF Γ 3.3V Γ 50MHz β 5 mA per pin. Total core + I/O current can reach ~200-250 mA in worst-case operation. Provide at least one 0.1 Β΅F decoupling capacitor per VCC pin (3 VCC pins total on the 44-TQFP) placed within 5 mm of each pin, plus a bulk 10 Β΅F tantalum on the 3.3 V rail. The internal 2.5 V regulator for the core does not require external bypass.
Route JTAG signals TMS, TCK, TDI, TDO as a daisy-chained bus with 4.7 kΞ© pull-ups on TMS and TDI per IEEE 1149.1 specification; keep trace length below 100 mm to preserve signal integrity at TCK frequencies up to 10 MHz. Place the JTAG header on the board edge for in-system programming access. For multi-voltage designs, separate VCCIO1 and VCCIO2 planes allow mixing 3.3 V and 5 V I/O on the same device β connect the unused I/O bank supply to the lower of the two interface voltages to avoid back-powering.
Do not confuse the EPM3032ATC44-10 with the 100-pin TQFP MAX II EPM240T100C5N β the MAX II has 240 logic elements and is NOT a drop-in replacement (different package, different pinout, different JTAG IDCODE). The MAX 3000A family is NRND per Intel PSG announcements; for new designs, migrate to MAX II (EPM240) or MAX V (5M80ZE64) CPLDs. When using legacy MAX+PLUS II design files in Quartus II, ensure device migration within MAX 3000A only β Quartus Prime (newer) does not support MAX 3000A.
Compliance Information
Original EPM3032ATC44-10 is Pb-bearing per Altera legacy convention; lead-free EPM3032ATC44-10N variant is RoHS compliant. NRND status per Intel PSG; check distributor availability.
