EPM3064ATI44-10NAD - MAX 3000A 64-Macrocell CPLD 44-TQFP | Altera
MPN: EPM3064ATI44-10NAD ✗ Cuối đờiEPM3064ATI44-10NAD Tóm tắt
A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell arrays interconnected by a central programmable interconnect matrix. CPLDs are part of the digital logic family, sitting between simple PLDs (PALs/GALs) and FPGAs in terms of density and complexity. They are characterized by predictable timing (deterministic pin-to-pin delays), instant-on operation (no boot time), and low static power consumption, making them ideal for glue logic, bus interfacing, and control-plane applications where FPGAs would be over-specified.
The EPM3064ATI44-10NAD offers 64 macrocells organized into 4 Logic Array Blocks (LABs) of 16 macrocells each, with a maximum of 34 I/O pins available in the 44-pin TQFP package. Programmable interconnect ties the LABs together, allowing wide combinatorial or registered logic functions to be synthesized. The 3.3 V core (VCCINT) operates from a single supply, while VCCIO can be independently driven at 3.3 V or 2.5 V to match downstream 2.5 V system logic without level shifters.
With 10 ns tPD (pin-to-pin delay) and 4.5 ns tSU (setup time), the device supports control logic operating at frequencies up to approximately 100 MHz on internal logic. ISP via JTAG (IEEE 1532) allows in-field reconfiguration without removing the part from the board. The IC has multi-voltage capability, JTAG programming support, and is part of the established MAX 3000A family known for deterministic timing.
Typical applications include industrial glue-logic replacement, address decoding and bus interfacing in legacy 3.3 V systems, state-machine and control-logic consolidation, peripheral chip-select generation, and power-sequencing logic for multi-rail systems. The -10N speed grade and 44-TQFP package remain widely available on the secondary market for legacy designs.
When designing with the EPM3064ATI44-10NAD, pay attention to the dual-marking on the top of the package; some lots carry both 'EPM3064ATI44-10N' and 'EPM3064ATC44-7N' markings. Plan I/O bank assignments for VCCIO (3.3 V or 2.5 V) before synthesis to avoid level-mismatch issues, and reserve the JTAG pins (TMS/TCK/TDI/TDO) for ISP access only.

Ứng dụng tiêu biểu
EPM3064ATI44-10NAD phù hợp cho 6 Áp dụngs: Industrial Glue Logic Replacement, Address Decoding and Chip-Select Generation, State Machine and Control Logic Consolidation, 3.3 V to 2.5 V Bus Interface Bridging, Power Sequencing for Multi-Rail Systems, Legacy Board Redesign and Obsolescence Management.
Industrial Glue Logic Replacement
The EPM3064ATI44-10NAD fits industrial glue-logic consolidation with its 64 macrocells, deterministic 10 ns tPD, and industrial -40C to +85C temperature grade. Its 34 user I/Os in the 44-pin TQFP package accommodate discrete 74-series logic replacement across wide logic functions. Compared to discrete TTL/CMOS implementations, this part reduces board area by 50-70% while preserving deterministic timing. Quartus II supports legacy MAX 3000A designs for direct compile, making it a reliable consolidation target. JTAG ISP (IEEE 1532) allows in-field logic updates.

Address Decoding and Chip-Select Generation
The EPM3064ATI44-10NAD excels at address decoding for microprocessor and microcontroller systems where multiple peripheral chip-selects must be generated from a single address bus. Its 10 ns tPD enables decoding in a single clock cycle at frequencies up to ~50 MHz, while 64 macrocells provide ample headroom for 8 to 16 independent chip-select outputs. The 3.3 V core with selectable 2.5 V or 3.3 V VCCIO allows direct interfacing to both 2.5 V and 3.3 V peripherals without level shifters, simplifying mixed-voltage system designs significantly.
Được đề xuất
State Machine and Control Logic Consolidation
Engineers use the EPM3064ATI44-10NAD to consolidate multi-chip state-machine implementations into a single non-volatile device, benefiting from the part's deterministic timing and instant-on operation. With 4 LABs of 16 macrocells each, complex multi-state control algorithms fit comfortably, while the 34 I/Os in TQFP-44 provide sufficient interface pins for status LEDs, enable signals, and interlock logic. The 10 ns pin-to-pin delay ensures glitch-free state transitions even under worst-case industrial conditions.
Được đề xuất
3.3 V to 2.5 V Bus Interface Bridging
The EPM3064ATI44-10NAD's selectable VCCIO (3.3 V or 2.5 V) makes it ideal as a level-translating bridge between mixed-voltage system domains. By splitting I/O banks across different VCCIO rails, a single part can interface 3.3 V microcontrollers with 2.5 V memory, DSPs, or ASICs without discrete level-shift ICs. The 10 ns propagation delay adds minimal latency to inter-bus transactions, and the 34 available I/Os support up to 17 bidirectional translating channels in TQFP-44.
Được đề xuất
Power Sequencing for Multi-Rail Systems
The EPM3064ATI44-10NAD serves as a configurable power-sequencing controller in multi-rail systems, where its non-volatile configuration, deterministic timing, and JTAG ISP are critical advantages. With 64 macrocells, multiple independent sequencer channels can be implemented with programmable delay chains for each rail's enable signal. The 3.3 V core and 2.5 V/3.3 V I/O compatibility allow direct interface to most PMBus and discrete enable inputs found in modern point-of-load converters and supervisor ICs.
Được đề xuất
Legacy Board Redesign and Obsolescence Management
The EPM3064ATI44-10NAD is frequently used to maintain legacy board designs where the original MAX 3000A part is obsolete or unavailable. Engineers performing obsolescence redesigns benefit from the part's identical 44-pin TQFP footprint across speed and temperature variants (ATI/ATC, -4/-7/-10), enabling last-time-buy substitution with the same Quartus II design files. JTAG IDCODE reading allows in-system verification of the installed die, ensuring that the migration is functionally equivalent to the original specification.

Ghi chú thiết kế
Decouple VCCINT and VCCIO with 0.1 uF ceramic capacitors placed within 5 mm of each supply pin, plus a bulk 10 uF tantalum or ceramic near the package. For multi-bank VCCIO designs where one bank is driven at 3.3 V and another at 2.5 V, place separate decoupling capacitors on each VCCIO pin pair to prevent cross-bank switching noise coupling.
Route JTAG signals (TMS, TCK, TDI, TDO) away from high-speed switching traces; keep TCK rise/fall times below 10 ns and add a 10 kohm pull-up on TCK and TMS for reliable boundary-scan operation. Do not share JTAG pins with user I/O functions - although MAX 3000A allows this, it complicates in-system programming and may cause ISP failures on production boards.
Verify the JTAG IDCODE before substituting a part with a different speed grade. According to Altera community reports, dual-marked physical parts may carry both 'EPM3064ATI44-10N' and 'EPM3064ATC44-7N' labels, which would otherwise cause timing failures if assumed equivalent. Always re-characterize critical paths after speed-grade substitution. Also confirm VCCIO voltage compatibility with downstream logic before board bring-up.
Estimated: at 50 MHz toggle rate with 16 outputs switching 10 pF loads, dynamic I/O current is approximately I = C*V*f = 16*10pF*3.3V*50MHz = 26 mA. Add core quiescent (~5 mA) for a total budget of ~31 mA. The TQFP-44 package (estimated theta_JA ~50 C/W on a 4-layer PCB with 1 oz copper) will rise ~25C above ambient under these conditions - well within industrial limits but worth measuring in sealed enclosures.
Thông tin tuân thủ
RoHS compliant per Altera/Intel product specifications. AEC-Q100 not applicable - this is a commercial/industrial programmable logic device, not an automotive-qualified IC. Industrial temperature grade (-40C to +85C) makes it suitable for industrial control but not automotive under-hood applications.
