EPM3064ATC44-7 - MAX 3000A CPLD, 64 Macrocells, 44-TQFP | Altera
MPN: EPM3064ATC44-7 ✗ Cuối đờiEPM3064ATC44-7 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that implements combinational and sequential logic using AND/OR arrays and flip-flops. CPLDs sit below FPGAs in the programmable logic hierarchy in terms of density, but offer deterministic timing, instant-on behavior, and high pin-to-pin logic density per package - making them ideal for glue logic, bus interfacing, and state-machine replacement in cost-sensitive designs.
Key features of the EPM3064ATC44-7 include MultiVolt I/O supporting 5.0V, 3.3V, and 2.5V logic interfaces, four JTAG-compliant pins for ISP and boundary-scan testing, PCI-SIG compliance for the -7 speed grade, and open-drain output options via the Quartus design software. The device operates from a single 3.3V supply with low standby current and supports up to 10,000 program/erase cycles.
The MAX 3000A architecture uses Logic Array Blocks (LABs) of 16 macrocells each, interconnected via a programmable interconnect array (PIA). Each macrocell contains a programmable AND/OR array, a flip-flop, and configurable output enable control. This architecture enables deterministic 7.5 ns pin-to-pin delays independent of logic placement, which is critical for asynchronous glue-logic applications.
Typical applications include bus decoding and address latch replacement in embedded systems, power-up sequencing logic in multi-rail designs, peripheral interface glue between microcontrollers and ASICs, and industrial control state machines. The device's instant-on non-volatile configuration eliminates external boot memory required by SRAM-based FPGAs.
Designers should note that the -7 speed grade is PCI-SIG compliant for Revision 2.2 local bus designs, and that ISP via JTAG requires 3.3V tolerance on TCK/TMS/TDI/TDO regardless of target logic levels. The EPM3064ATC44-7 is now considered legacy hardware, with newer MAX V or MAX II CPLDs recommended for new designs.
This page synthesizes distributor pricing, drop-in alternatives, comparison data, and design guidance not found in the original Altera MAX 3000A datasheet - enabling faster sourcing and second-source decisions for legacy CPLD designs.

Ứng dụng tiêu biểu
EPM3064ATC44-7 phù hợp cho 6 Áp dụngs: Bus Decoding and Address Latch Replacement, Power-Up Sequencing Logic, Peripheral Interface Glue Logic, Industrial Control State Machines, Legacy PCI Local Bus Interface, Test and Measurement Front-End Logic.
Bus Decoding and Address Latch Replacement
The EPM3064ATC44-7 is well suited for bus decoding and address-latch replacement in embedded systems where deterministic timing is critical. With 64 macrocells and a 7.5 ns pin-to-pin delay, it can decode up to 64 unique address combinations while comfortably handling 50 MHz memory buses. The MultiVolt I/O supports 5.0V microprocessor buses alongside 3.3V memory without external level shifters. Placed between a microcontroller and SRAM/Flash, it eliminates discrete 74-series glue logic, freeing board space and improving reliability. The non-volatile EEPROM configuration means instant-on decoding with no boot delay - critical for systems that must respond immediately at power-up.
Được đề xuất
Power-Up Sequencing Logic
The EPM3064ATC44-7 provides reliable power-up sequencing logic for multi-rail systems, ensuring DC-DC converters, ASICs, and FPGAs start in the correct order. Its 34 user I/Os can monitor up to 8-10 enable signals and assert up to 16-20 sequencing outputs with programmable delays. The instant-on EEPROM configuration means sequencing logic is active within microseconds of power-up, before any MCU boots - critical for hardware-based sequencing that cannot depend on software. Its deterministic 7.5 ns propagation enables precise timing across multiple rails. The JTAG ISP interface allows in-field sequencing-logic updates without board removal.
Được đề xuất
Peripheral Interface Glue Logic
The EPM3064ATC44-7 is widely used as glue logic between microcontrollers, ASICs, and peripherals with mismatched interfaces. Its 64 macrocells can implement multiple interface bridges (UART to SPI, I2C to parallel GPIO) within a single chip, replacing 3-5 discrete logic ICs. The MultiVolt I/O interface enables direct connection to 5.0V, 3.3V, and 2.5V devices without external level translation. Designers leverage Quartus II to capture complex interface logic as HDL and synthesize it into the CPLD, dramatically reducing PCB area and BOM cost in industrial control and consumer products.
Được đề xuất
Industrial Control State Machines
The EPM3064ATC44-7 implements deterministic state machines for industrial automation, replacing mechanical relays and discrete logic in motor control, conveyor sequencing, and process control. With 192.3 MHz maximum counter frequency and 7.5 ns propagation, it can service sensors and actuators in real time at industrial cycle rates. Its commercial operating temperature range (0C to +70C) suits factory-floor enclosures. The 34 user I/Os handle multiple sensor inputs and relay outputs from a single device, while JTAG ISP allows firmware updates without removing boards from equipment.
Được đề xuất
Legacy PCI Local Bus Interface
The EPM3064ATC44-7 is PCI-SIG Revision 2.2 compliant at its -7 speed grade, making it suitable for legacy 33 MHz PCI Local Bus designs requiring address decoding, command decoding, and parity logic. The 7.5 ns pin-to-pin delay comfortably meets the 33 MHz PCI timing budget with substantial margin. The MultiVolt I/O connects directly to 5.0V PCI signals without external buffers. For new PCI Express designs, consider migrating to MAX II or Cyclone IV FPGAs, but for maintaining legacy PCI add-in cards and embedded systems, the EPM3064ATC44-7 remains a proven solution.
Được đề xuất
Test and Measurement Front-End Logic
The EPM3064ATC44-7 provides programmable front-end logic for test and measurement instruments, handling signal routing, range switching, and trigger conditioning before signals reach ADCs or counters. Its deterministic 7.5 ns propagation preserves measurement timing accuracy, while 64 macrocells implement complex trigger logic and timing sequences. The JTAG ISP allows engineers to update measurement algorithms without hardware changes - useful during prototype development. The 44-pin TQFP package suits compact bench instruments and OEM test modules where board space is constrained.

Ghi chú thiết kế
Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the device, with a 10 uF tantalum or aluminum polymer bulk capacitor on the 3.3V supply rail. The TQFP-44 package has four VCC pins and three GND pins distributed around the package; ensure all are connected with wide traces to maintain signal integrity and reduce ground bounce. For MultiVolt I/O mixing 5.0V and 3.3V signals, route the higher-voltage traces with at least 0.2 mm spacing from 3.3V traces to prevent coupling.
Do not confuse the EPM3064ATC44-7 (this part, 7.5 ns) with the EPM3064ATC44-7N (lead-free, identical speed) - both have the same datasheet ordering code but different plating. Verify the marking on physical parts before assembly, as dual-marking schemes have caused confusion between the EPM3064ATC44-7N and EPM3064ATI44-10N per Altera Community discussion 323852. For new designs, ensure JTAG pins TCK/TMS/TDI/TDO have 10 kohm pull-ups to VCC(IO) as recommended by the MAX 3000A datasheet, otherwise ISP programming may fail intermittently.
Assign high-frequency output signals to pins adjacent to GND pins to minimize simultaneous switching noise (SSN). The MAX 3000A datasheet recommends limiting simultaneously switching outputs to a maximum of 16 pins per I/O bank to avoid ground bounce exceeding 0.8V. Use the Quartus II fitter reports to verify I/O bank utilization and SSN analysis before layout signoff. For designs migrating from EPM3032ATC44 to EPM3064ATC44, the pinout is identical in TQFP-44, but verify any I/O voltage reference (VREF) pin assignments in the Quartus pin planner.
