EPM3064ATC44-10 - 64-Macrocell MAX 3000A CPLD, TQFP-44 | Altera
MPN: EPM3064ATC44-10 ✗ Cuối đờiEPM3064ATC44-10 Tóm tắt
A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on digital IC that integrates multiple PAL-like logic blocks (called macrocells or LABs) on a single die. CPLDs sit hierarchically between simple PLDs (PAL/GAL) and larger FPGAs: like FPGAs they implement arbitrary combinatorial and sequential logic, but unlike FPGAs they boot in microseconds from on-chip EEPROM, run deterministic timing, and consume very low standby current. They belong to the broader family of programmable logic devices within the digital semiconductor hierarchy.
Key electrical features of the EPM3064ATC44-10 include 3.0 V to 3.6 V core operation (3.3 V typical), 4.5 ns to 10 ns propagation delay grades, multiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and IEEE 1149.1 (JTAG) boundary-scan test support. Each macrocell contains a programmable AND/OR array, a flipflop, and a product-term allocator that delivers up to 32 product terms per macrocell. The architecture is optimized for glue logic, bus interfacing, and state-machine replacement where deterministic timing and instant-on behavior are critical.
Typical applications include bus bridging between processors and peripherals, address decoding and chip-select generation, interface voltage translation, and small state machines in telecom, industrial control, and consumer products. Because the configuration is stored in on-chip EEPROM, the part is ideal for low-volume, long-lifecycle designs where a discrete logic implementation would be too large or rigid. The wide I/O count (34 user I/Os on this TQFP-44) makes it a flexible substitute for multiple 74-series TTL/CMOS packages.
When designing with the EPM3064ATC44-10, ensure the Quartus II or MAX+PLUS II design toolchain supports the legacy MAX 3000A device family and produces a POF bitstream. Decouple VCCINT and VCCIO with 0.1 µF ceramic capacitors placed within 5 mm of each supply pin. Leave the JTAG pins (TCK, TMS, TDI, TDO) accessible for factory programming and boundary-scan test.

Ứng dụng tiêu biểu
EPM3064ATC44-10 phù hợp cho 7 Áp dụngs: Bus Bridge and Address Decoder, Voltage Level Translation (multiVolt I/O), Industrial Control and PLC Logic, Legacy Peripheral Replacement (74-series Glue Logic), JTAG-Programmable State Machine and Controller, Telecom and Datacom Interface Cards, Test and Measurement Front-End Logic.
Bus Bridge and Address Decoder
The EPM3064ATC44-10 fits bus-bridge and chip-select decoding roles because its 64 macrocells (1,250 usable gates) easily encode wide AND-OR address match terms, and the 10 ns tPD is fast enough for asynchronous memory and peripheral decoding on 33 MHz buses. The 34 programmable I/Os comfortably route 16- to 24-bit address buses plus several chip-select outputs. Because configuration lives in on-chip EEPROM, the part powers up with valid decode outputs in microseconds, eliminating the wait-for-FPGA-boot that complicates designs built around SRAM FPGAs. Typical placement: between a 3.3 V processor local bus and 3.3 V or 5 V-tolerant peripherals, with JTAG exposed for factory programming.

Voltage Level Translation (multiVolt I/O)
Each I/O bank on the EPM3064ATC44-10 can be powered independently at 1.5 V, 1.8 V, 2.5 V, or 3.3 V, which makes the part a single-chip level translator between mixed-voltage domains on the same PCB. For example, one bank at 1.8 V can talk to a low-voltage ASIC while a second bank at 3.3 V drives legacy peripherals, all stitched together with internal logic. Designers use this to replace discrete resistor dividers, MOSFET level shifters, and dedicated translator ICs, saving board area. The 10 ns tPD adds only a few nanoseconds to inter-domain paths, well within typical asynchronous handshake budgets for UART, SPI, and GPIO bridging.

Industrial Control and PLC Logic
Industrial PLCs and motor controllers benefit from the EPM3064ATC44-10's deterministic timing, instant-on from EEPROM, and tolerance to 5 V inputs on 3.3 V outputs - the 5 V-tolerant I/O let the part sense 24 V-receiving optocoupler outputs through resistor dividers. The 64-macrocell capacity covers typical state machines for sequencing, fault detection, and watchdog logic. The 10 ns propagation delay is fast enough to debounce and qualify digital inputs in real time before passing them to a host microcontroller. Although the commercial 0C-70C grade limits deployment to indoor cabinets, the EPM3064ALI44-10N industrial variant extends operation to -40C to +85C for harsh industrial environments.

Legacy Peripheral Replacement (74-series Glue Logic)
One EPM3064ATC44-10 can replace dozens of 74HC/74F/74LS series TTL packages - decoders, multiplexers, latches, flipflops, and small state machines - all on a 10 x 10 mm TQFP-44 footprint. Engineers use this to consolidate board area, reduce BOM count, and obsolete-proof designs against 74-series EOL. The 34 user I/Os comfortably cover the I/O count of 8-12 discrete logic packages, and the EEPROM configuration lets the same silicon implement different board functions by changing only the POF bitstream. This application is a strong driver for the part's adoption in telecom and instrumentation backplanes.

JTAG-Programmable State Machine and Controller
The EPM3064ATC44-10 is often deployed as a stand-alone state-machine controller that can be re-programmed in-system via JTAG (IEEE Std. 1532 and IEEE 1149.1 boundary scan). Typical uses include custom timing generators, watchdog timers, sequencers for power-rail bring-up, and pattern generators in test equipment. The non-volatile EEPROM means firmware revisions can be pushed through JTAG in the factory or even in the field without removing the part. Boundary-scan chains through TDI/TDO also let the CPLD act as a JTAG bridge for downstream parts that lack their own TAP, simplifying board-level test fixtures.

Telecom and Datacom Interface Cards
Telecom line cards and datacom interface adapters use the EPM3064ATC44-10 to implement hardware-side glue between FPGAs/ASICs and standard backplane interfaces, including LVCMOS-to-LVDS bridging, clock distribution, and interrupt aggregation. The 1.25K usable gates are sufficient to qualify clocks, generate frame pulses, and arbitrate bus contention without loading the host ASIC. Combined with multiVolt I/O, the CPLD can directly interface legacy 5 V PHYs on older line cards. Designers benefit from deterministic 10 ns tPD for latency-critical paths such as TDM bus timing and SerDes reference-clock steering.
Được đề xuất
Test and Measurement Front-End Logic
Instrument makers use the EPM3064ATC44-10 as a reconfigurable front-end for signal routing, range switching, and trigger logic in oscilloscopes, logic analyzers, and bench-top testers. The 34 I/Os and 64 macrocells handle 8- to 16-channel multiplexers, Schmitt-trigger input conditioning, and trigger comparators. EEPROM programmability lets the same hardware platform ship with multiple personality bitstreams for different product SKUs. The 10 ns propagation delay is short enough to qualify edges for trigger logic without introducing jitter into the measurement path, which is critical for sub-nanosecond timing accuracy.

Ghi chú thiết kế
The EPM3064ATC44-10 requires a stable 3.3 V supply on VCCINT and a separate VCCIO per I/O bank. Place a 0.1 µF ceramic decoupling capacitor within 5 mm of each VCCINT and VCCIO pin, and add a bulk 10 µF tantalum or ceramic cap near the package. Because the I/O banks can run at 1.5 V, 1.8 V, 2.5 V, or 3.3 V independently, never tie VCCIO pins together if you intend to mix voltage domains on the same die. Power sequencing is not required; the EEPROM configuration is valid at first power-up.
The TQFP-44 package has a 0.8 mm pitch and a 10 x 10 mm body - allow at least 12 x 12 mm of board area including solder-pad expansion for reliable assembly. Route JTAG signals (TCK, TMS, TDI, TDO) as a daisy-chained or star net from the programming header with no stubs, and place a 4.7 kΩ pull-up on TCK and TMS per IEEE 1149.1 recommendations. If the design uses multiple CPLDs in a JTAG chain, order them so TDO of one feeds TDI of the next; verify chain integrity with the Quartus II programmer before final assembly.
Do not confuse the obsolete EPM3064ATC44-10 (lead-bearing) with the RoHS-compliant EPM3064ATC44-10N when ordering for production - they are functionally identical but only the 'N' variant satisfies RoHS directives. Do not exceed 3.6 V on VCCINT, and observe the 5 V tolerance limit on I/O pins when interfacing legacy 5 V signals. Finally, the Quartus II toolchain dropped MAX 3000A support after version 13.0; use legacy Quartus II 13.0 or MAX+PLUS II for new bitstreams and verify POF files against the target device ID before deployment.
