Typical Applications
EPM3032ATI44-10N is suitable for 6 applications: Board-Level Glue Logic Replacement, Address Decoding and Bus Interfacing, State-Machine and Sequencer Control, I/O Expansion for Microcontrollers, LED and Display Multiplexing Drivers, Power-Up and Power-Down Sequencing Logic.
Board-Level Glue Logic Replacement
The EPM3032ATI44-10N is widely used to replace discrete 74LS/74HC glue logic on industrial PCBs because its 32 macrocells and 600 usable gates consolidate dozens of AND/OR gates, muxes, and latches into a single non-volatile device. With a 10 ns pin-to-pin delay and 103.1 MHz counter frequency, it comfortably drives address decoding, interrupt steering, and chip-select generation at bus speeds up to ~50 MHz. The MultiVolt I/O directly interfaces with 5.0 V, 3.3 V, and 2.5 V buses without external level shifters, simplifying mixed-voltage retrofits.
Recommended
Address Decoding and Bus Interfacing
The EPM3032ATI44-10N is a strong fit for address decoding and peripheral chip-select generation on ISA, PCI, and proprietary local buses because its 32 macrocells provide ample AND/OR plane capacity for full 24-bit address decoding with multiple chip-select outputs. The 10 ns tPD combined with deterministic MAX-architecture timing gives a fixed, datasheet-specified propagation delay that simplifies worst-case AC timing analysis versus FPGA soft-IP. The 34 user I/Os handle multi-bank memory or peripheral decoding without I/O expansion.
Recommended
State-Machine and Sequencer Control
The EPM3032ATI44-10N is well suited for implementing Moore/Mealy state machines, power-up sequencers, and watchdog controllers in industrial control systems because its EEPROM-based configuration is non-volatile and the device powers up already configured - no external boot PROM is needed. The 32 macrocells typically realize 8-12 states with multiple outputs, while the 10 ns tPD and 103.1 MHz counter frequency are sufficient for sequencing power rails, stepper motors, and relay drivers at millisecond to microsecond timing resolution.
Recommended
I/O Expansion for Microcontrollers
The EPM3032ATI44-10N provides cost-effective I/O expansion for legacy 8051, PIC, and ARM microcontrollers that have insufficient GPIOs for keypad scanning, LED multiplexing, or relay driving. Its 34 user I/Os - well beyond the 16-24 GPIO budget of many microcontrollers - are routed through JTAG-programmable logic and retain their last state through power cycles thanks to the EEPROM cell array. The MultiVolt I/O and 3.3 V core supply make it a natural companion to 3.3 V MCU families like the NXP LPC and STM32 lines.
Recommended
LED and Display Multiplexing Drivers
The EPM3032ATI44-10N is commonly deployed as a Charlieplex/Charlie-display or row-column multiplex driver for small LED matrices and 7-segment displays, where its 34 I/Os can scan up to 8x8 matrices or six 7-segment digits with BCD decoding implemented in macrocell logic. The 10 ns tPD and 103.1 MHz fCNT comfortably support refresh rates above 100 Hz to avoid visible flicker, while the non-volatile EEPROM configuration means the display mapping persists across power cycles without re-flashing.
Recommended
Power-Up and Power-Down Sequencing Logic
The EPM3032ATI44-10N is widely used for power-rail sequencing in telecom line cards, industrial controllers, and ATCA/ATX backplanes where multiple supply rails must come up in a specific order to satisfy inrush, latch-up, and POR constraints. The 32 macrocells implement cascaded timers and interlock logic, while the JTAG/IEEE 1532 ISP interface allows in-field re-programming of sequencing waveforms without board rework. Hot-socketing support lets the device be inserted into a live backplane without disrupting adjacent rails.

Key Differentiators
- Industrial operating temperature range in a TQFP-44 footprint (vs EPM3032ATC44-10N)
- 10 ns speed grade balances cost and timing margin (vs EPM3032ATC44-7N)
- IEEE 1532 ISP compliance enables multi-vendor programming (vs EPM7032AETC44-10N)
Design Notes
Estimated: route the four JTAG pins (TCK/TMS/TDI/TDO) as a short daisy-chain to the CPLD, keeping trace length under 50 mm and avoiding parallel routing to high-edge-rate clocks. Place a 0.1 uF decoupling capacitor on each VCCINT pin and a 0.1 uF cap on each VCCIO bank within 3 mm of the package pin. Add a bulk 10 uF tantalum or ceramic near the TQFP-44 supply pins to suppress board-level switching transients during ISP programming.
Do not apply voltage to any I/O pin before VCCINT has reached its 3.0 V minimum, even though the device advertises hot-socketing support. Hot-socketing is specified only when VCCINT is fully ramped and stable. Driving 5 V into a MultiVolt I/O pin while VCCINT is at 0 V can latch the device through the I/O ESD clamp diodes and cause permanent damage.
Keep the TQFP-44 thermal pad (exposed pad, if present on the package variant) soldered to a continuous ground pour of at least 100 mm^2 on both top and inner layers, stitched with 0.3 mm vias on a 1 mm grid. This provides a low-inductance ground return for JTAG ISP programming and helps the EEPROM configuration memory stay within its read endurance specification during repeated in-field re-programming.
Estimated: the MAX 3000A 10 ns grade has typical output rise/fall times of 2-3 ns at 50 pF load, producing edge rates of ~1 V/ns. Route output traces as 50 ohm microstrip with a ground reference plane within 0.2 mm; avoid stubs and use series termination only when the trace length exceeds 1/6 of the rise-time distance (~25 mm at this edge rate). The MultiVolt I/O pins tolerate 5 V inputs only when VCCIO is 3.3 V or 2.5 V; do not exceed 4.0 V on any I/O when VCCIO = 2.5 V.
Compliance Information
RoHS non-compliant (contains lead) per digchip.info part listing; AEC-Q100 not applicable since this is a general-purpose CPLD rather than an automotive-grade IC. REACH, halogen-free, and conflict-mineral declarations were not found in the verified data - set to 'unknown' rather than guess.
