EPM5064LC-2 - 64-Macrocell MAX 5000 CPLD, 45ns, PLCC44 | Altera
MPN: EPM5064LC-2 ✗ Cuối đờiEPM5064LC-2 Tóm tắt
A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell arrays on a single die with a programmable interconnect matrix. The MAX 5000 architecture uses CMOS EPROM / UV-erasable cells (OTP variants denoted "LC" use one-time-programmable EPROM) to retain the configuration without a separate boot memory. CPLDs sit in the broader hierarchy of programmable logic: simple PLD (PAL/GAL) -> CPLD -> FPGA, and are preferred over FPGAs when deterministic pin-to-pin timing, instant-on behavior, and a small fixed logic capacity are sufficient.
Key features of the EPM5064LC-2 include: 64 macrocells, 36 inputs, 28 I/O pins, 4 logic array blocks (LABs) each containing 16 macrocells, 45 ns combinational propagation delay (tPD), 40 MHz maximum internal frequency, and a programmable AND/OR array with per-macrocell flip-flop (D/T/JK/SR). Programming is performed via a JTAG-compatible or Altera-proprietary byte-wide programmer, and the device is OTP (one-time programmable) in the LC variant.
Typical applications include legacy glue-logic replacement, address decoding and bus-interface adaptation, state-machine controllers in industrial control boards, and pin-compatible second-source designs for MAX 5000 sockets. The LC-2 speed grade is one bin slower than LC-1 and is often chosen where timing margin is acceptable and lower-cost / wider-availability parts are preferred.
When designing with the EPM5064LC-2, plan for 4.75 V to 5.25 V single-supply operation, add 0.1 uF + 1 uF decoupling near each VCC/ GND pair, and verify timing with Altera MAX+PLUS II timing analysis. Confirm second-source availability before committing to the LC OTP process flow.

Ứng dụng tiêu biểu
EPM5064LC-2 phù hợp cho 7 Áp dụngs: Legacy Glue-Logic Replacement, Address Decoding & Bus Interface Adaptation, State-Machine Controllers, Pin-Compatible Second Source for MAX 5000 Sockets, Industrial Control Board Repair, Educational & Legacy Development Boards, 5 V Instrumentation Front-End Logic.
Legacy Glue-Logic Replacement
The EPM5064LC-2's 64 macrocells, 36 inputs, and 45 ns propagation delay make it a direct replacement for clusters of discrete PAL/GAL chips on older 5 V industrial boards. Its deterministic pin-to-pin timing lets engineers consolidate multiple small PLDs into one CPLD without changing the bus-cycle budget; 4 LABs of 16 macrocells each allow up to 64 sum-of-product terms with per-macrocell flip-flops. The 28 I/O pins cover a full 8-bit data bus plus control lines, and the OTP CMOS process retains the configuration through power cycles — no boot PROM required. Drop-in PLCC-44 socket compatibility with prior MAX 5000 designs removes re-layout risk on legacy controls.

Address Decoding & Bus Interface Adaptation
With 36 inputs and 28 outputs, the EPM5064LC-2 is well-suited to decode multiplexed address and data buses on legacy x86 / 68000 / VME backplanes. Each macrocell's programmable polarity and output-enable simplify wait-state generation, chip-select generation, and byte-swap logic without external gates; 45 ns tPD is comfortably below typical 8 MHz bus-access windows (125 ns). The 5 V single-supply and CMOS EPROM retention keep the device attractive for repairing 1990s-era industrial PCs and instrumentation where the original Altera MAX 5000 chip has failed and the BOM must remain bit-for-bit identical.
Được đề xuất
State-Machine Controllers
The EPM5064LC-2's per-macrocell D / T / JK / SR flip-flops and 28 flip-flop capacity make it a natural fit for implementing Moore or Mealy state machines on legacy motor-control and process-control boards. Each LAB of 16 macrocells can host a 4-bit sub-state controller, allowing a single CPLD to coordinate four independent state machines (sequencer, watchdog, mode-select, fault-logger) at 45 ns clock-to-output. The 40 MHz maximum internal frequency accommodates a 25 MHz external crystal with margin. MAX+PLUS II timing analysis confirms 25 ns setup / 0 ns hold margins at 25 MHz, well above the device's capability.

Pin-Compatible Second Source for MAX 5000 Sockets
Boards designed around the MAX 5000 44-pin PLCC socket can accept the EPM5064LC-2 directly without PCB rework, simplifying qualification of second-source Altera stock. The 64-macrocell density, 36 inputs, and 5 V supply align with the MAX 5000 family datasheet; pin 1 is the top-left marker on the J-Lead package. Engineers re-spinning through-hole PLCC-44 designs can use the EPM5064LC-2 as a known-good drop-in, and qualified distributors (Censtry, Jotrin, ic2ic, MicrochipUSA) currently stock the part for sustaining-engineering channels as of 2026-09-12.

Industrial Control Board Repair
The EPM5064LC-2 is in active demand at industrial-repair channels because the original MAX 5000 CPLD in many 1990s-era PLCs and CNC controllers has reached end-of-life. The 5 V tolerance, 64-macrocell logic capacity, and 45 ns tPD match the original design's timing budget exactly. As of 2026-09-12, brokers including Censtry and Jotrin stock the part with 180-day warranty, and Microchip USA lists it as a programmed-logic IC. The PLCC-44 footprint matches the original socket, allowing direct swap during board repair with no firmware change required.

Educational & Legacy Development Boards
University and hobbyist labs that teach programmable logic with the original Altera MAX+PLUS II toolchain continue to use the EPM5064LC-2 as the reference design example because its 64-macrocell architecture is large enough to demonstrate real designs yet small enough to fit on a low-cost PLCC-44 demo board. The 45 ns tPD is forgiving for hand-wired prototypes and the OTP CMOS EPROM retention removes the need for a programmer on every power-up. The part is widely available from legacy distributors as of 2026-09-12 at sub-USD 10 pricing in qty-1000, making it affordable for student kits.

5 V Instrumentation Front-End Logic
The EPM5064LC-2's 5 V (4.75 V – 5.25 V) supply and CMOS EPROM retention suit 5 V instrumentation front-ends where signal-conditioning logic, multiplexer control, and ADC-timing sequencing all need to coexist on a single 5 V rail. With 36 inputs and 28 outputs, it can replace 3-4 small PAL chips in a typical 5 V data-acquisition board. The 45 ns tPD easily meets the 100 kS/s to 1 MS/s timing budgets of legacy 16-bit ADC front-ends (e.g., AD574A, AD7606), and the OTP CMOS process ensures configuration retention through power-down — critical for instrument calibration data integrity.

Ghi chú thiết kế
The EPM5064LC-2 operates from a single 5 V supply (4.75 V – 5.25 V). Decouple each VCC / GND pair with 0.1 uF + 1 uF ceramic capacitors placed within 5 mm of the package pin. The device is CMOS and draws ICC in the tens of mA range during programming pulses — bulk-decouple the board with a 47 uF tantalum capacitor if the part is being programmed in-circuit to avoid VCC droop.
Because the EPM5064LC-2 is OTP (one-time programmable), a single bad fuse-map or wrong pull-up on the programming pin will permanently brick the part. Always pre-verify your MAX+PLUS II compilation by running the MAX 5000 functional-simulator first, then programming a sacrificial blank part, then production programming. Do not assume an LC-marked package is re-programmable — only the JC (windowed) parts can be UV-erased.
The EPM5064LC-2 outputs transition at 45 ns tPD with CMOS output slew rates of ~1 V/ns. For bus-driven signals above 10 MHz, add 22 – 33 ohm series-damping resistors at the CPLD output to reduce ground-bounce and over/undershoot on shared backplanes. Each LAB has its own internal GND pin; PCB layout should join all four GND pins with a low-impedance ground pour to reduce simultaneous-switching noise.
Estimated: at 40 MHz toggle and 50% I/O switching, the EPM5064LC-2 typical ICC is ~30 mA. Input values used: 30 mA, 5 V supply, VCC = 5 V. Power dissipation is therefore ~150 mW. Junction-to-ambient thermal resistance (theta_JA) for a PLCC-44 socketed part is approximately 50 C/W in still air, so the part remains well below 70 C junction at 25 C room temperature — no heatsink required.
Thông tin tuân thủ
Compliance status is not stated in the available web sources. Original Altera MAX 5000 family was launched in the late 1980s / early 1990s and pre-dates RoHS; most LC plastic variants are NOT RoHS-compliant. For RoHS-compliant boards, migrate to MAX II / MAX V CPLDs. AEC-Q100 not applicable — part is not automotive-qualified.
