EPM3064ATC44-10NAF - 64-Macrocell MAX 3000A CPLD, 10ns TQFP-44 | Intel
MPN: EPM3064ATC44-10NAF ✗ Cuối đờiEPM3064ATC44-10NAF Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocells on a single die, providing predictable timing, instant-on operation, and wide input-gluing capability. Within the broader taxonomy, CPLDs sit between simple SPLDs/PLDs and larger FPGAs, serving glue-logic, interface bridging, and power-up state-machine roles where deterministic timing and zero-boot-delay configuration are mandatory. The MAX 3000A family from Intel/Altera uses EEPROM-based configuration cells, so the device retains its logic image even after power removal without an external boot PROM.
Key features include 64 macrocells organized into 4 logic array blocks (LABs) of 16 macrocells each, 1250 usable gates, 34 I/O pins with multi-voltage I/O support, IEEE Std. 1149.1 JTAG boundary-scan test (BST) and IEEE Std. 1532 in-system programmability, and a 10 ns maximum propagation delay from input pin to output pin. The device also provides a global Clear signal, four pin-compatible I/O standards, and pin-locking capability that preserves the board layout across design iterations. Programmable interconnect uses the Altera Classic / MAX architecture with continuous routing that simplifies timing closure.
The EPM3064ATC44-10NAF is built on a 5 V-tolerant I/O structure with multi-voltage I/O capability for interfacing with 3.3 V, 2.5 V, and 1.8 V logic without external level shifters. Internal pull-up resistors on every I/O simplify board layout by eliminating external resistors on unused or tri-stated pins. The EEPROM configuration cell is rated for 100 erase/program cycles, suiting design-stage iteration and field upgrades via JTAG. The TQFP-44 (10x10 mm) package is a JEDEC-standard thin quad flat pack suitable for reflow soldering.
Typical applications include bus and peripheral interface bridging (e.g., address decoding between an MCU and SRAM), state-machine and control-logic replacement for 74LS/HC discrete glue, power-up sequencing logic for FPGAs and SoCs, and small bus-multiplexing/level-translation bridges. Designers choose MAX 3000A parts when they need instant-on, deterministic-timed logic without the cost or complexity of an SRAM-based FPGA. In cost-sensitive industrial controls and consumer electronics, the EPM3064A series is often the lowest-cost CPLD for sub-128 macrocell designs.
When designing with this device, plan a 100 nF decoupling capacitor adjacent to every VCCIO/VCCINT pair, keep JTAG TMS/TCK/TDO/TDI traces short and series-terminated, and configure unused I/O pins as outputs driving low or as inputs with internal weak pull-ups enabled. Confirm Quartus II MAX+PLUS II or legacy MAX+PLUS II compatibility, because the MAX 3000A family is supported by Altera/Intel MAX+PLUS II and Quartus II design software but is NOT supported by modern Quartus Prime Pro/Standard editions.

Ứng dụng tiêu biểu
EPM3064ATC44-10NAF phù hợp cho 6 Áp dụngs: Address Decoding & Bus Bridging, FPGA / SoC Power-Up Sequencing, Industrial Control Glue Logic, Legacy Peripheral Emulation, Communication Interface Bridging, Consumer Electronics Display & Control Logic.
Address Decoding & Bus Bridging
The EPM3064ATC44-10NAF is purpose-built for address decoding and bus-bridging logic between microcontrollers, memory, and peripherals. With 64 macrocells and 10 ns tPD propagation delay, it can decode wide address ranges and assert chip selects in a single logic level, eliminating cascaded 74LS/HC gates. The non-volatile EEPROM configuration provides instant-on chip-select assertion at power-up with zero boot delay, which is critical for legacy x86 and 68k systems that require valid memory selects before the first instruction fetch. The 34 I/O pins easily handle 24-bit address plus 8-bit data-direction decoding for SRAM, Flash, and peripheral CS outputs. Multi-voltage I/O (3.3 V/2.5 V/1.8 V) allows direct interfacing to modern SoCs without external level shifters. Typical companion parts are the EPM240T100 (larger MAX II CPLD for follow-on designs) and any 8051/MIPS MCU.

FPGA / SoC Power-Up Sequencing
The EPM3064ATC44-10NAF excels at power-supply sequencing for FPGAs, SoCs, and multi-rail processor designs. Its EEPROM-based configuration powers up in a known deterministic state, asserting enable signals to DC-DC converters, LDOs, and reset generators in the correct order before the host FPGA/SoC releases its POR signal. With 10 ns tPD it can sequence 4-6 rails within a few hundred nanoseconds, well below the typical 50 ms POR timeout of modern processors. The 1250-gate capacity easily implements watchdog timers, voltage-rail fault OR-ing, and power-good signal combination. JTAG programming (IEEE 1149.1) allows field updates to the sequencing order without board rework. Typical companion parts include the TPS7A4701 LDO and a small MCU supervisor such as the TPS3823.

Industrial Control Glue Logic
The EPM3064ATC44-10NAF is widely deployed in industrial control systems to replace discrete 74LS/HC/ACT logic with a single programmable device, reducing PCB area and improving noise immunity. Industrial applications include PLC digital I/O expansion, motor-control interface logic, encoder-signal quadrature decoders, and isolated UART/SPI bridges. The deterministic 10 ns timing makes it suitable for time-critical control loops and protocol-bit-banging where FPGA boot time is unacceptable. Multi-voltage I/O compatibility directly interfaces 5 V industrial sensors to 3.3 V microcontrollers. The TQFP-44 package is robust enough for industrial temperature ranges and reflow-compatible with standard lead-free processes. Typical companion parts include industrial MCU families (e.g., STM32, PIC18) and isolated RS-485 transceivers.
Được đề xuất
Legacy Peripheral Emulation
The EPM3064ATC44-10NAF is often used to emulate legacy peripherals such as PC/AT bus chips, ISA address latches, and parallel-port interfaces in modernized systems. The 64-macrocell capacity can implement a complete 8-bit or 16-bit peripheral register file with read/write strobes in a single chip. The 10 ns propagation delay meets ISA bus timing (8 MHz / 125 ns cycle) with substantial margin. IEEE 1149.1 boundary-scan test (BST) simplifies board-level test of complex legacy interconnects. Designers can reprogram the same TQFP-44 footprint to emulate different peripherals during design development. Typical companion parts are SRAM chips (e.g., 62C256) and legacy 74-series glue-logic ICs that the CPLD replaces.
Được đề xuất
Communication Interface Bridging
The EPM3064ATC44-10NAF bridges mismatched communication interfaces such as UART-to-SPI, SPI-to-I2C, or parallel-to-serial converters in embedded systems. With 34 I/O pins and 1250 gates it can implement a multi-channel UART/SPI bridge with hardware FIFO control, eliminating the need for a dedicated protocol-converter IC. The 10 ns timing supports UART bit-rates up to ~50 Mbps and SPI clocks beyond 30 MHz. Multi-voltage I/O allows direct connection to 5 V sensors and 1.8 V SoCs without external level translation. JTAG ISP enables field reprogramming when bridging requirements change. Typical companion parts include RS-232/RS-485 transceivers and any modern microcontroller with UART/SPI peripherals.

Consumer Electronics Display & Control Logic
The EPM3064ATC44-10NAF is used in consumer electronics for display-interface control, button-matrix decoding, and LED-driving multiplexing. Its non-volatile EEPROM eliminates configuration delays so display backlights, keypads, and indicators operate the instant power is applied - critical for TV, set-top box, and appliance user-perceived responsiveness. The 34 I/Os can scan a 5x5 button matrix plus drive up to 16 LED channels. Pin-locking across design iterations preserves PCB layout, accelerating product development cycles. The compact 10x10 mm TQFP-44 fits inside tight consumer enclosures. Typical companion parts include LED drivers (e.g., TLC5941) and small LCD/OLED displays.

Ghi chú thiết kế
The EPM3064ATC44-10NAF requires two power rails: VCCINT (3.0-3.6 V) on pin 43 and VCCIO (3.0-3.6 V) on pin 42. Place a 100 nF decoupling capacitor within 5 mm of each VCC pin and a 10 uF bulk capacitor on the supply rail. The device draws approximately 50-100 mA active depending on switching frequency; ensure the LDO or DC-DC converter provides at least 200 mA headroom. Power sequencing between VCCINT and VCCIO is not required; both rails may ramp together.
The TQFP-44 (10x10 mm) package has 0.8 mm pitch leads requiring careful PCB layout: keep traces short, use 0.2 mm/8 mil trace width with 0.2 mm spacing, and place a continuous ground plane on the layer beneath the CPLD for thermal dissipation and signal integrity. JTAG signals TMS, TCK, TDI, TDO should be routed together with 22-33 ohm series termination to reduce ringing on long traces; add a 10 kohm pull-up on TCK and TMS to keep JTAG in a defined state during board reset.
The MAX 3000A family is supported by legacy Altera MAX+PLUS II and Quartus II (versions up to 13.0) but is NOT supported by modern Quartus Prime Pro/Standard. Attempting to compile a MAX 3000A design in Quartus Prime will fail. Plan to maintain legacy software or migrate new designs to MAX II (EPM240) or MAX V (5M40ZE64) devices. Additionally, the 100 erase/program cycle EEPROM limit means the device should not be used for high-reprogram applications such as FPGA bitstream reconfiguration; instead use SRAM-based FPGAs for those use cases.
Configure unused I/O pins as outputs driving low or as inputs with internal weak pull-ups enabled (default in MAX+PLUS II / Quartus II). Do not leave unused pins floating - this increases power consumption and noise susceptibility. Reserve JTAG pins (TDI/TMS/TCK/TDO) for programming access even if not used in the application circuit, and provide a JTAG header on the PCB so firmware can be updated in-circuit. Pin-locking across speed-grade migration (-10 to -7 or -4) is fully supported, so design the PCB to accept any speed-grade variant.
