EPM3064ATC44-7N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a programmable interconnect matrix, sitting in the programmable logic hierarchy between simple SPLDs and larger FPGAs. CPLDs typically offer deterministic, near-zero standby power, instant-on operation from EEPROM configuration, and are widely used for glue logic, bus interfacing, state-machine control, and I/O expansion where predictable timing matters more than raw logic density.
Key features of the EPM3064ATC44-7N include 3.3 V in-system programmability (ISP) through a built-in IEEE Std. 1149.1 JTAG interface with advanced pin-locking, ISP circuitry compliant with IEEE Std. 1532 for concurrent multi-vendor programming, multiVolt I/O supporting 1.8 V/2.5 V/3.3 V interfacing, and built-in boundary-scan test (BST) circuitry. The -7 speed grade specifies a 7.5 ns pin-to-pin delay, while the -10 grade operates at 10 ns for cost-sensitive designs.
Architecturally, the device uses Altera's classic MAX architecture with each Logic Array Block containing 16 macrocells fed by a programmable AND array and a product-term allocator that routes terms to OR gates. EEPROM configuration cells provide non-volatile storage, so the device powers up instantly with no external boot PROM. The multiVolt core allows mixed-voltage interfacing without external level shifters, easing integration into modern low-voltage ASIC/FPGA designs.
Typical applications include bus interface bridging (e.g., address decoding between processors and peripherals), power-up sequencing logic, configuration controllers for FPGAs and microcontrollers, peripheral I/O expansion, and glue-logic replacement for discrete 74-series TTL in industrial control, communications, and consumer systems. The 44-pin TQFP footprint matches the entire EPM3064AT family, allowing drop-in migration between speed grades.
When designing with this part, ensure VCCIO is supplied on the correct pin (pin 13 on the 44-pin TQFP) and JTAG signals TDI/TDO/TMS/TCK are brought out for ISP. Decouple each VCC/VCCIO pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and use the Quartus II or MAX+PLUS II toolchain for design entry and programming file generation.

Applications typiques
EPM3064ATC44-7N convient pour 6 applications: Bus Interface & Address Decoding, Power-Up Sequencing & Reset Control, FPGA Configuration Controller, Industrial Control & State Machines, Glue Logic Replacement (74-series), Communications & Peripheral I/O Expansion.
Bus Interface & Address Decoding
The EPM3064ATC44-7N excels at bus interface bridging and address decoding between microprocessors, memory, and peripherals. With 64 macro cells it can decode multi-bank chip-select signals across 24-bit address spaces, generate wait-state timing, and translate between 8/16/32-bit bus protocols. Its 7.5 ns pin-to-pin delay is fast enough for ISA-style buses and modern SPI/I2C peripheral expansion, while the 3.3 V core with multiVolt I/O (1.8 V/2.5 V/3.3 V) lets it interface directly with legacy 5 V-tolerant logic via external resistors. Unlike an FPGA, the EEPROM-backed CPLD powers up instantly with valid outputs, eliminating boot-ROM sequencing in deterministic control paths.
Recommandé
Power-Up Sequencing & Reset Control
The EPM3064ATC44-7N is well-suited to multi-rail power-up sequencing in FPGA, ASIC, and SoC designs that require deterministic rail order. Its 64 macro cells can implement cascaded timers, voltage-good monitors feeding the JTAG-controlled I/O pins, and programmable watchdog logic. Because configuration is stored in EEPROM, sequencing starts within microseconds of VCC ramp, far faster than microcontroller-based sequencers that require firmware boot. The 7.5 ns tPD enables glitch-free propagation of fault signals, and the 3.3 V core operates from the same rail that often supplies the supervisor itself, simplifying BOM cost.
Recommandé
FPGA Configuration Controller
The EPM3064ATC44-7N serves as a low-cost configuration controller for larger FPGAs (Cyclone, Stratix, Spartan families) in industrial and embedded systems. With 64 macro cells it can generate the configuration clock, control PROGRAM_B/INIT_B/DONE handshakes, and select between multiple bitstreams stored in parallel flash. The IEEE 1149.1 JTAG ISP interface allows in-field reconfiguration without external programmers, while the multiVolt I/O bridges between 3.3 V CPLD rails and 1.8 V/2.5 V FPGA configuration banks. Compared with discrete 74-series sequencers, the integrated solution reduces board area and improves timing margin in mission-critical boot paths.
Recommandé
Industrial Control & State Machines
The EPM3064ATC44-7N is widely deployed in industrial controllers where deterministic, fail-safe state machines drive relays, motor starters, and process valves. Its 192.3 MHz maximum counter frequency supports high-resolution PWM and quadrature decoding, while the 34 user I/Os can directly interface with 24 V industrial sensors via optocouplers on each pin. The EEPROM non-volatile configuration ensures the controller resumes its last state through power cycles without external watchdog or supervisor ICs. Compared to microcontroller-based implementations, the CPLD's parallel logic execution avoids interrupt-latency jitter in hard-real-time control loops.
Recommandé
Glue Logic Replacement (74-series)
The EPM3064ATC44-7N replaces multiple discrete 74LS/74HC/74FTTL packages (decoders, multiplexers, flip-flops, latches) with a single programmable device, saving PCB area and reducing BOM cost in mature designs. With 64 macro cells it can absorb 10-20 equivalent TTL packages, integrating functions that would otherwise span multiple footprints. The 44-pin TQFP occupies the same board area as four 16-pin SOICs, and the in-system programmability via JTAG allows last-minute logic changes without board respins. This application is a classic MAX 3000A use case where Altera's MAX+PLUS II / Quartus II toolchains accept TTL schematics directly.
Recommandé
Communications & Peripheral I/O Expansion
The EPM3064ATC44-7N expands I/O and protocol-conversion capability in communications equipment such as routers, base stations, and serial-backplane aggregators. Its multiVolt I/O supports mixed 1.8 V/2.5 V/3.3 V domains commonly found in PHYs, while the 7.5 ns tPD suits LVDS-style point-to-point links at modest baud rates. The CPLD can implement UART/SPI/I2C bridges, parallel-to-serial converters, and protocol-format adapters without consuming the main CPU's interrupt bandwidth. The 34 user I/Os and 64 macro cells are enough to manage multiple low-speed serial channels alongside an Ethernet or PCIe control plane.

Principaux différenciateurs
- Balanced speed/cost grade in the MAX 3000A 64-macrocell family (vs EPM3064ATC44-4N)
- Faster and higher-frequency-capable than the smaller EPM3032ATC44-7N (vs EPM3032ATC44-7N)
- Wider speed envelope than the EPM3064ATC44-10N with same die (vs EPM3064ATC44-10N)
Notes de conception
The EPM3064ATC44-7N requires two separate supplies: VCC at 3.3 V for the core (pin 35) and VCCIO at 1.8 V, 2.5 V, or 3.3 V for the I/O bank (pin 13). Place a 0.1 µF decoupling capacitor within 5 mm of each supply pin, plus a 10 µF bulk capacitor near the package. During in-system programming, VCC must ramp monotonically from 0 V to 3.3 V within the datasheet's tRAMP specification, or ISP will fail. If VCCIO is held at 0 V while VCC is active, the I/O pins enter a high-impedance state but the core continues operating.
Place a 4-layer PCB stack-up with a dedicated ground plane immediately below the TQFP to minimize switching noise coupling into JTAG and clock pins. The 44-pin TQFP has a 0.8 mm pitch and a thermal pad-style lead frame, so use 0.15 mm trace/space design rules and route all JTAG signals (TDI/TDO/TMS/TCK on pins 30/44/31/32) on the top layer with short, parallel traces. Series-terminate clock outputs driving long traces (>50 mm) with 33 Ω resistors to control ringing. Do not route switching signals under the device footprint to avoid coupling into the EEPROM charge pumps.
Three pitfalls frequently trip up first-time users of the MAX 3000A family. First, the JTAG chain must include a 1 kΩ pull-up on TCK and TMS, and a 1 kΩ pull-up on TDI, per the IEEE 1149.1 specification, or ISP programming will fail intermittently. Second, the device IDCODE is 0x026040DD for the EPM3064A family; if your JTAG chain reports a different ID, re-check the BSDL file. Third, the global clear (GCLK1/GCLRn) pin must be tied high or driven high within 100 µs of VCC stable or all registers will reset to an undefined state. According to Altera application notes, the legacy MAX+PLUS II toolchain is required for MAX 3000A; Quartus Prime does not directly support this family.
