EPM3032ATI44-10N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a programmable interconnect fabric. CPLDs sit in the hierarchy between simple SPLDs (PALs/GALs) and larger FPGAs: they offer deterministic timing, instant-on EEPROM configuration, modest logic capacity (hundreds to thousands of gates), and are typically used for glue logic, bus interfacing, state-machine control, and I/O expansion. The MAX 3000A family is the 3.3-V low-cost tier of Altera's MAX architecture.
Key features include 600 usable gates, a 103.1 MHz internal counter frequency, 3.3-V core supply with MultiVolt I/O supporting 5.0-V, 3.3-V, and 2.5-V logic interfaces, in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface and IEEE Std. 1532 compliance, and hot-socketing support. The 'I' suffix designates the industrial operating temperature range of -40C to +85C. The 10-ns speed grade (tPD = 10 ns) makes this part suitable for general-purpose logic replacement and control applications that do not require the fastest 4.5-ns MAX 3000A grades.
The device is fabricated on an EEPROM-based CMOS process, which provides non-volatile configuration memory - the design is retained without an external boot PROM and the device powers up instantly ready to operate. The MAX architecture uses a classic Logic Array Block (LAB) structure with a programmable interconnect matrix (PIA), giving deterministic timing that simplifies static timing analysis compared to FPGAs.
Typical applications include 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, and power-up/power-down sequencing logic. Industrial automation, telecom line cards, and legacy industrial PC peripherals are common end-use markets.
When designing with this device, ensure the JTAG chain is correctly ordered if multiple IEEE 1149.1 devices share the same TDI/TDO path, and verify that 5-V-tolerant I/O pins are not driven above 5.25 V absolute maximum even briefly during hot-socketing transients.

Applications typiques
EPM3032ATI44-10N convient pour 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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.

Notes de conception
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.
