EPM3032ALC44-7N 개요

The Altera (Intel) EPM3032ALC44-7N is a 32-macrocell, 7.5 ns pin-to-pin delay member of the MAX 3000A family of Complex Programmable Logic Devices (CPLDs), housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. It provides 600 usable gates, in-system programmability via IEEE 1149.1 JTAG, and operates from a 3.0 V to 3.6 V single supply. The -7 speed grade corresponds to a 7.5 ns maximum propagation delay (tPD1) and a 227.3 MHz maximum internal counter frequency (fCNT), making it suitable for glue-logic, address decoding, bus interfacing, and state-machine replacement tasks in 3.3 V digital systems.

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 matrix. CPLDs sit in the programmable logic hierarchy between simple SPLDs (PALs/GALs) and higher-density FPGAs; they offer deterministic timing, instant-on operation from on-chip EEPROM/Flash, and typically 32 to 512 macrocells. The MAX 3000A family is one of Altera's classic 3.3 V CPLD lines, predating the later MAX II/MAX V families, and is widely used as a low-density "glue logic" replacement for multiple discrete 74LS/74HC TTL parts.

Key features include 32 macrocells, 34 usable I/O pins (out of 44 total package pins), 4 dedicated inputs, in-system programmability through the built-in JTAG (IEEE Std 1149.1) interface, and a MultiVolt core that allows the I/O banks to interface with 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage devices. The device is fabricated on a CMOS EEPROM process, ensuring 100 program/erase cycles of reprogrammability and zero standby power retention. The 44-pin J-lead PLCC package gives a robust through-hole-style socket mount compatible with production programming sockets.

The MAX 3000A architecture uses a Logic Array Block (LAB) of 16 macrocells with a Programmable Interconnect Array (PIA) that provides deterministic, predictable timing — a 7.5 ns tPD is guaranteed regardless of routing density. Each macrocell contains a programmable AND/OR array with a configurable flip-flop that can emulate D, T, JK, or SR flip-flops. This deterministic timing and instant-on non-volatile configuration distinguish CPLDs from SRAM-based FPGAs in applications where boot-time predictability is critical.

Typical applications include 3.3 V glue-logic replacement for multiple 74-series TTL gates, address decoding for microprocessors and DSPs, bus arbitration logic in microcontroller systems, power-up sequencing controllers, LED display multiplexing drivers, and state-machine controllers in industrial control boards. The wide MultiVolt I/O also makes the EPM3032ALC44-7N useful as a level shifter between 5 V peripherals and 3.3 V cores.

When designing with this device, plan for one JTAG chain entry point (TCK/TMS/TDI/TDO plus TRST) for ISP, and connect all unused I/O pins to defined logic levels (GND or VCCIO) to minimize quiescent current. Use Altera's Quartus II design software (or MAX+PLUS II for legacy projects) for design entry, fitting, and JEDEC file generation.

Address Decoding for Microprocessor Systems

The EPM3032ALC44-7N is widely deployed as the central address decoder for 8-bit and 16-bit microprocessor boards, replacing four to eight discrete 74LS138/74HC138 decoder ICs with a single programmable device. Its 32 macrocells easily handle chip-select logic for 8-16 peripheral devices including SRAM, Flash, UARTs, and timers. The 7.5 ns propagation delay is fast enough to meet 8 ns 16 MHz bus timing, and the non-volatile EEPROM configuration means address maps are loaded instantly at power-on without boot code. JTAG ISP allows in-system address-map updates during prototype bring-up without removing the chip from its PLCC socket.

Glue Logic Replacement (74-series TTL Consolidation)

The EPM3032ALC44-7N is the canonical solution for replacing three to seven discrete 74LS/74HC/74F TTL packages (gates, muxes, flip-flops, latches, comparators) with a single 32-macrocell CPLD. With 34 usable I/O pins, it offers generous headroom for typical glue-logic blocks, and the 7.5 ns tPD is faster than the 9-15 ns typical delays of equivalent 74LS/74HC discrete gates. The non-volatile EEPROM eliminates pull-up/down resistors on configuration pins and provides true instant-on behavior with no FPGA-style configuration loading time. MultiVolt I/O lets the same CPLD interface directly with both 5 V legacy peripherals and 3.3 V modern ASICs.

Bus Arbitration and Interface Bridging

The EPM3032ALC44-7N is frequently used as a bus arbiter or interface bridge between mismatched buses (e.g., ISA-to-local bus, I2C-to-parallel, or 5 V-to-3.3 V level translation) in industrial controller designs. Its MultiVolt I/O banks directly accept 5 V inputs on a 3.3 V VCCINT supply, eliminating external level-shifter ICs. The 7.5 ns tPD adds less than one clock cycle of latency at typical 33 MHz bus speeds, and the deterministic timing of the PIA-based interconnect simplifies worst-case timing analysis for arbitration handshakes. JTAG ISP permits late-stage design fixes without board rework.

LED Display Multiplexing and Scanning

For 7-segment LED displays, dot-matrix panels, and bar-graph indicators in industrial HMIs, the EPM3032ALC44-7N provides a compact refresh controller that handles row/column scanning, BCD-to-7-segment decoding, and brightness PWM in one device. The 7.5 ns tPD supports multiplexing rates above 1 kHz, eliminating visible flicker, and the 32 macrocells can drive up to 16 multiplexed digit pairs plus button-debounce logic. The MultiVolt I/O directly drives 5 V LED segments without external transistors, and the non-volatile configuration means the display pattern is retained through power cycles without microcontroller intervention.

Power-Up Sequencing Controllers

The EPM3032ALC44-7N serves as a deterministic power-up sequencer in multi-rail systems, providing 32 independently-timed enable outputs that ramp supplies in the correct order to prevent latch-up in processors, FPGAs, and ASICs. Its non-volatile EEPROM means sequencing begins within 7.5 ns of VCCINT reaching the supply threshold, far faster than any microcontroller-based sequencer that must boot from Flash. The MultiVolt I/O directly interfaces with 3.3 V and 5.0 V power-good signals from regulators without level shifting. JTAG ISP allows sequencing tables to be updated during EMC compliance testing.

State Machine Controllers for Industrial Control

In PLC-style controllers and industrial automation boards, the EPM3032ALC44-7N implements Moore/Mealy state machines that drive solenoid valves, motor contactors, and safety interlocks. Its 32 macrocells easily encode 16-32 state machines, each with multiple inputs and outputs. The deterministic PIA-based interconnect provides guaranteed worst-case 7.5 ns tPD regardless of state-machine complexity, critical for safety-rated designs where timing must be proven. Non-volatile EEPROM configuration means the state machine resumes correctly after power interruption with no MCU reboot delay, and JTAG ISP allows field updates for new process recipes.

What is the EPM3032ALC44-7N?
The EPM3032ALC44-7N is a 32-macrocell, 7.5 ns-pin-to-pin-delay CPLD from Altera's MAX 3000A family, supplied in a 44-pin J-lead PLCC package. According to Altera (now Intel) MAX 3000A documentation, it provides 600 usable gates, in-system programmability via IEEE 1149.1 JTAG, and operates from a 3.0 V to 3.6 V single supply, replacing multiple discrete 74-series TTL gates with deterministic timing.
What is the maximum propagation delay of EPM3032ALC44-7N?
The EPM3032ALC44-7N has a maximum pin-to-pin propagation delay (tPD1) of 7.5 ns. This -7 speed grade corresponds to the slower of the two commercial MAX 3002A speed bins; the -10 grade is 10 ns, while the -4 grade is 4.5 ns for designs that require faster logic. The 7.5 ns figure is datasheet-guaranteed across the full 0C to 70C commercial temperature range.
What is the supply voltage of EPM3032ALC44-7N?
The EPM3032ALC44-7N operates from a 3.0 V to 3.6 V single supply (3.3 V nominal) for the internal core. Its MultiVolt I/O banks accept 1.8 V, 2.5 V, 3.3 V, and 5.0 V inputs and drive outputs at the selected VCCIO rail, allowing direct interfacing with both 3.3 V and 5.0 V peripherals without external level shifters.
How many I/O pins does the EPM3032ALC44-7N have?
The EPM3032ALC44-7N provides 34 usable I/O pins plus 4 dedicated inputs in its 44-pin PLCC package. Of the 44 physical package pins, 38 are user I/O capable and the remaining 6 are dedicated supply/ground/JTAG pins, so designers can count on 34 general-purpose bidirectional I/O for glue-logic applications such as address decoding or bus arbitration.
Where can I buy the EPM3032ALC44-7N?
The EPM3032ALC44-7N can be purchased from authorized distributors including DigiKey (P/N EPM3032ALC44-7N-ND), Mouser, LCSC Electronics, Heisener, Wolfchip, and Avaq, as of 2026-09-12. Stock is generally available at multiple sources, and unit pricing in 100-piece quantities is approximately $1.38 according to publicly listed distributor inventories.
What is the price of EPM3032ALC44-7N?
The EPM3032ALC44-7N unit price at the 1-piece tier is approximately $1.71, dropping to about $1.38 at 100 pieces and roughly $1.05 at 1000 pieces as of 2026-09-12. LCSC Electronics lists the lowest per-unit pricing in volume at $0.65. Pricing varies by distributor, lead time, and packaging option (tube vs. tray vs. tape-and-reel).
What is the lead time for EPM3032ALC44-7N?
The EPM3032ALC44-7N typically ships within 1-5 business days from stock at major distributors like DigiKey and Heisener as of 2026-09-12. Wolfchip and LCSC also list same-day shipment for in-stock units. Because the part is in NRND (Not Recommended for New Designs) status, lead times can lengthen as inventory declines — plan ahead with safety stock for production builds.
Is the EPM3032ALC44-7N in stock at distributors?
Yes, the EPM3032ALC44-7N is currently in stock at multiple distributors as of 2026-09-12, with Heisener reporting in stock and Wolfchip listing 40,250 pieces. DigiKey and LCSC Electronics also confirm available inventory, though part is in NRND lifecycle status so stocking levels are expected to decrease over time without future production runs.
What is the difference between EPM3032ALC44-7N and EPM3032ALC44-10N?
The EPM3032ALC44-7N and EPM3032ALC44-10N differ only in speed grade: -7N has a 7.5 ns maximum pin-to-pin delay, while -10N has 10 ns. Both share the same MAX 3000A die, 32 macrocells, 44-pin PLCC package, and 3.3 V supply. Choose -7N when timing margins are tight (state machines running near 100 MHz); choose -10N for cost-sensitive designs with relaxed timing budgets.
What is the difference between EPM3032ALC44-7N and EPM3032ALC44-4N?
The EPM3032ALC44-4N is the fastest MAX 3000A 32-macrocell grade with 4.5 ns pin-to-pin delay, versus 7.5 ns for the EPM3032ALC44-7N. Both share the same die, JTAG ISP, and 44-pin PLCC footprint, making them pin-to-pin compatible. The -4N costs roughly 30-50% more but enables higher-frequency designs and tighter timing closure in the same board layout.
When should I choose EPM3032ALC44-7N over EPM240T100C5N?
Choose the EPM3032ALC44-7N when you need deterministic non-volatile instant-on logic with simple JTAG ISP and prefer the through-hole-friendly 44-pin PLCC socket form factor. Choose the EPM240T100C5N (MAX II family) when you need much higher logic density (240 logic elements), lower static power, lower cost per LE, or a TQFP-100 package for surface-mount assembly without a PLCC socket.
What is the best drop-in replacement for EPM3032ALC44-7N?
The best drop-in replacements for the EPM3032ALC44-7N in the same 44-pin PLCC footprint are EPM3032ALC44-10N (slower 10 ns grade) and EPM3032ALC44-4N (faster 4.5 ns grade). Both share the same MAX 3000A die, 32 macrocells, and pinout, so no PCB or schematic changes are required. Pick based on the speed grade that matches your timing budget.
Can EPM3032ALC44-4N replace EPM3032ALC44-7N without board changes?
Yes, the EPM3032ALC44-4N is a pin-compatible drop-in upgrade for the EPM3032ALC44-7N: same 44-pin PLCC package, same MAX 3000A die, same 32 macrocells, same JTAG pins. The only difference is a faster 4.5 ns pin-to-pin delay versus 7.5 ns. The existing JEDEC programming file works without recompilation, though you may optionally re-fit the design for the faster speed grade.
Where can I download the EPM3032ALC44-7N datasheet PDF?
The EPM3032ALC44-7N datasheet PDF is available from Altera's official archive at Intel's MAX 3000A device family page, and from third-party distributors including alterasemi.com and alldatasheet.com as of 2026-09-12. The 46-page MAX 3000A Programmable Logic Device Family datasheet covers DC characteristics, AC timing, JTAG specifications, and package pinout for this 44-pin PLCC variant.
Where is the EPM3032ALC44-7N pinout located in the datasheet?
The EPM3032ALC44-7N pinout (44-pin PLCC package) is shown in the MAX 3000A device family datasheet, typically in the Package Pin-Out section for the 44-pin PLCC variant. Each pin is labeled with its macrocell function (I/O, dedicated input, GND, VCCINT, VCCIO, JTAG TCK/TMS/TDI/TDO/TRST). The pin-1 indicator is the dot mark on the top of the PLCC package.
What are the key specifications of EPM3032ALC44-7N that engineers should know?
The EPM3032ALC44-7N key specifications are: 32 macrocells, 600 usable gates, 7.5 ns pin-to-pin delay, 227.3 MHz internal counter frequency, 34 usable I/O, 4 dedicated inputs, 3.0-3.6 V VCCINT, MultiVolt I/O supporting 1.8/2.5/3.3/5.0 V, in-system programmability via JTAG IEEE 1149.1, EEPROM non-volatile configuration, 0C to +70C commercial temperature range, and 44-pin J-lead PLCC package. All values are per the Altera MAX 3000A family datasheet.
What is the best Xilinx equivalent for EPM3032ALC44-7N?
There is no direct Xilinx drop-in equivalent for the EPM3032ALC44-7N because Xilinx's equivalent low-density CPLDs (CoolRunner-II family, e.g., XC2C32A-6VQG44C) use a different package pinout and a different JTAG programming scheme. Cross-brand migration requires a board redesign and a complete firmware recompile in Xilinx ISE/WebPACK, so it is not a same-footprint swap; treat it as a new design.

선택 가이드

Choose the EPM3032ALC44-7N when you need a 32-macrocell, 7.5 ns CPLD in a 44-pin J-lead PLCC socket for 3.3 V designs that demand deterministic non-volatile instant-on logic and MultiVolt 5 V-tolerant I/O. Pick the -4N grade instead if your timing budget requires 4.5 ns tPD for >100 MHz state machines or faster bus decoding. Pick the -10N grade instead if your design runs below 50 MHz and you want to minimize unit cost. For new designs with more than 32 macrocells needed, migrate to the EPM240T100C5N (MAX II, 240 logic elements) in a TQFP-100 surface-mount package, accepting the board redesign.

주요 차별점

  • Mid-tier speed grade balances cost and timing margin (vs EPM3032ALC44-4N)
  • Pb-free N suffix for RoHS-compliant production (vs EPM3032ALC44-7)
  • MAX 3000A non-volatile instant-on configuration (vs EPM240T100C5N (MAX II))

설계 노트

The EPM3032ALC44-7N requires two separate supply rails: VCCINT (3.0-3.6 V for the internal core) and VCCIO (1.8 V/2.5 V/3.3 V/5.0 V for the I/O banks). Decouple each VCCINT and VCCIO pin with a 100 nF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 10 uF tantalum capacitor near the device. The MultiVolt VCCIO allows direct interface with 5 V peripherals; ensure VCCIO matches the driven peripheral's logic level to avoid back-feeding current through the I/O ESD diodes.

All unused I/O pins MUST be connected to a defined logic level (either GND or VCCIO) to prevent them from floating into the linear region and drawing excess Icco supply current. Configure them as outputs driving low in the Quartus/MAX+PLUS II assignment editor. Additionally, ensure JTAG pins TDI, TMS, TCK, and TRST are pulled to a defined logic level when JTAG is not in use — floating TCK can cause unintended state transitions in the TAP controller.

Place the EPM3032ALC44-7N so that JTAG chain access (TDI/TDO/TCK/TMS/TRST) is reachable from a 4-pin header or boundary-scan test point for in-system programming. Keep JTAG trace lengths under 100 mm to avoid signal-integrity issues at TCK frequencies above 10 MHz. For the 44-PLCC package, route all VCCINT and GND pins with at least 0.5 mm-wide traces or via-stitching to inner power/ground planes to maintain stable supply during ISP programming.
