EPM3064ATI44-10 - 64-Macrocell MAX 3000A CPLD, TQFP-44 | Intel / Altera
MPN: EPM3064ATI44-10 ✗ Cuối đờiEPM3064ATI44-10 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the hierarchy between simple SPLDs/PLDs and high-density FPGAs. Compared with FPGAs, CPLDs use non-volatile EEPROM or flash configuration memory (instant-on, no boot time) and a coarse-grained macrocell architecture optimized for wide combinational/registered logic, bus bridging, and glue-logic replacement. MAX 3000A belongs to the EEPROM-based CPLD category - LDO -> CPLD family -> programmable logic -> digital logic IC -> semiconductor - and competes with Xilinx XC9500XL, Lattice ispMACH 4000, and Microchip ATF1500 families.
Key features include 64 macrocells across four logic array blocks (LABs), 34 user I/O pins, 10 ns pin-to-pin tPD, and counter speeds up to 227.3 MHz. MultiVolt I/O supports interfacing to 1.8 V, 2.5 V, 3.3 V and 5.0 V logic without external level shifters, while an internal charge pump supports in-system programming of the EEPROM array via the standard 4-pin JTAG (IEEE 1149.1) interface.
Architecturally, the device combines a programmable interconnect array, four LABs each containing 16 macrocells, a global control signal network, and an IEEE 1149.1 boundary-scan test interface. The EEPROM configuration cell is rated for 100 program/erase cycles and provides instant-on behavior with zero configuration latency at power-up - a defining advantage over SRAM-based FPGAs in deterministic boot applications.
Typical applications include industrial control glue logic, address decoding and bus interfacing, motor control peripheral expansion, legacy microcontroller peripheral replacement, and power-sequencing logic in telecom/networking backplane hardware. The wide operating temperature range and 5 V-tolerant I/O make the part particularly attractive for industrial and telecom designs where 3.3 V MCUs must interface to 5 V peripherals.
When designing with this device, reserve JTAG pins (TDI, TDO, TMS, TCK) for ISP - they cannot be used as general-purpose I/O without disabling JTAG. Provide a clean 3.3 V supply with adequate bulk decoupling, since EEPROM programming transients draw additional current during in-system updates.

Ứng dụng tiêu biểu
EPM3064ATI44-10 phù hợp cho 6 Áp dụngs: Industrial Control Glue Logic, Address Decoding and Bus Interfacing, Legacy Microcontroller Peripheral Replacement, Power Sequencing in Telecom/Networking Backplanes, Motor Control Peripheral Expansion, Communication Protocol Bridging (UART/SPI/I2C).
Industrial Control Glue Logic
The EPM3064ATI44-10's 64 macrocells, 34 user I/O, and 10 ns tPD make it ideal for industrial control glue logic where deterministic, instant-on logic replaces discrete 74HC/MSI chips. With 5.0 V tolerant I/O via MultiVolt, the device bridges 3.3 V microcontrollers to legacy 5 V peripheral drivers, opto-isolators, and relay coils without external level shifters. The EEPROM-based non-volatile configuration boots in microseconds - critical for fail-safe PLC and motor-drive designs where SRAM-FPGA boot delays are unacceptable. Place the device between the MCU address/data bus and the peripheral decoder logic, with JTAG (TCK, TMS, TDI, TDO) reserved for in-field ISP during commissioning.

Address Decoding and Bus Interfacing
The 10 ns tPD and 227.3 MHz counter frequency suit the EPM3064ATI44-10 for address decoding and bus-bridging applications, such as generating chip-select signals for memory banks, mapping multiplexed address/data buses, or creating custom peripheral-select logic for embedded systems. With 64 macrocells and 34 I/O, it can decode wide address ranges (e.g., 24-bit to 32-bit) and produce multiple staggered chip-select outputs with configurable wait-state insertion. The instant-on EEPROM configuration eliminates FPGA bitstream-load delays on power-up - a key advantage in boot-loader designs where the CPLD must assert decode logic before the CPU fetches its first instruction.
Được đề xuất
Legacy Microcontroller Peripheral Replacement
The EPM3064ATI44-10 is frequently used to replace obsolete microcontroller peripherals (e.g., 8255 PPI, 8253 PIT, 16450 UART) by re-implementing their register interfaces in CPLD logic. With 64 macrocells, a single device can typically emulate one full peripheral block, while 5 V tolerant I/O and 3.3 V core voltage match the electrical profile of legacy +5 V or modern +3.3 V systems. The JTAG (IEEE 1149.1) ISP interface enables in-circuit firmware updates during board bring-up and field servicing. Drop the part onto the original peripheral's footprint and re-emulate the register map in Verilog/VHDL for cost-effective legacy system support.
Được đề xuất
Power Sequencing in Telecom/Networking Backplanes
The EPM3064ATI44-10's deterministic instant-on behavior makes it well suited for power-sequencing logic in telecom and networking backplane hardware, where multiple DC-DC converters must be enabled in a precise order (e.g., 1.0 V core before 1.8 V before 3.3 V before 5.0 V) to prevent latch-up or in-rush damage. Each macrocell can implement a delay timer or voltage-good comparator, and the 34 I/O pins can drive PG (power-good) and EN lines for up to 16 power rails. The -40C to +85C industrial temperature range and 5 V tolerant I/O ensure reliable operation in thermally demanding central-office and edge-router environments.
Được đề xuất
Motor Control Peripheral Expansion
The 64 macrocells and 10 ns tPD of the EPM3064ATI44-10 enable implementation of PWM generation, quadrature encoder decoding, and Hall-sensor interface logic for motor control applications. The 227.3 MHz counter speed supports high-resolution PWM at switching frequencies up to several hundred kHz, while 34 I/O pins can simultaneously drive 3-phase inverter signals, capture encoder inputs, and interface to the host DSP/MCU. The industrial temperature grade (-40C to +85C) and 5 V tolerant I/O suit industrial servo drives, where 5 V analog feedback and 3.3 V DSP logic coexist on the same PCB.
Được đề xuất
Communication Protocol Bridging (UART/SPI/I2C)
The EPM3064ATI44-10 can bridge between mismatched serial protocols - UART-to-SPI, SPI-to-I2C, I2C-to-parallel - in industrial and embedded designs where the host MCU lacks the required peripheral. With 64 macrocells, multiple simple bridges can coexist in one device, and the 34 I/O pins can be allocated across multiple channels. The 5 V tolerant I/O is particularly valuable when bridging modern 3.3 V MCUs to legacy 5 V sensors or RS-232/RS-485 transceivers. Program the device via JTAG during prototype bring-up; once the bitstream is verified, EEPROM configuration locks the design in non-volatile memory for production.

Ghi chú thiết kế
The EPM3064ATI44-10 requires a clean 3.3 V core supply (VCCINT on pin 38 in TQFP-44). Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VCC pin, plus a 10 uF bulk capacitor near the device. During in-system programming via JTAG, the internal charge pump draws additional transient current - ensure the 3.3 V regulator can source at least 200 mA peak. Avoid sharing the VCC rail with high-noise switching converters; route the CPLD supply from a filtered LDO output if the system 3.3 V is generated by a buck regulator.
For TQFP-44 layout, allocate a 10x10 mm land pattern with 0.8 mm pitch and follow standard JEDEC MS-026 guidelines. Route JTAG signals (TDI, TDO, TMS, TCK) as a short daisy-chain with 10-22 ohm series termination if the TCK frequency exceeds 10 MHz. The four ground pins (pin 10, 21, plus GND on remaining pads) must each connect to a continuous ground plane via short vias - this is critical for signal integrity on the 5 V tolerant I/O banks. Keep clock inputs away from I/O switching lines to minimize simultaneous-switching-noise (SSN) coupling into the JTAG test logic.
Do NOT use the four JTAG pins (TDI pin 30, TMS pin 31, TCK pin 32, TDO pin 44 in TQFP-44) as general-purpose I/O without disabling JTAG in the Quartus design - leaving JTAG enabled consumes the pins and may cause contention during ISP. Verify the bitstream file is compiled for the correct speed grade (-10 = 10 ns tPD) before programming; loading a -7 or -4 bitstream into a -10 device can produce timing violations. Finally, confirm the silicon revision matches: the T (industrial temp) and C (commercial temp) suffixes are NOT interchangeable for outdoor or automotive designs where the operating temperature can drop below 0C.
