EPM3032ALC44-7N - 32-Macrocell 7.5ns CPLD | Altera MAX 3000A
MPN: EPM3032ALC44-7N ✗ Cuối đờiEPM3032ALC44-7N Tóm tắt
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.

Ứng dụng tiêu biểu
EPM3032ALC44-7N phù hợp cho 6 Áp dụngs: Address Decoding for Microprocessor Systems, Glue Logic Replacement (74-series TTL Consolidation), Bus Arbitration and Interface Bridging, LED Display Multiplexing and Scanning, Power-Up Sequencing Controllers, State Machine Controllers for Industrial Control.
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

Ghi chú thiết kế
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.
