EPM1270T144A5N Présentation

The Intel (formerly Altera) EPM1270T144A5N is a MAX II family Complex Programmable Logic Device (CPLD) delivering 980 macro cells and 1270 logic elements in a 144-pin TQFP (T144) surface-mount package. It features a maximum propagation delay of 6.2 ns and supports internal supply voltages of 2.5 V and 3.3 V with an operating supply range of 2.375 V to 3.6 V, making it well-suited for low-power glue-logic and bus-interface bridging in 3.3 V systems.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a centralized interconnect matrix. It sits in the programmable logic hierarchy between simple SPLDs (e.g. PAL/GAL) and high-density FPGAs. CPLDs are valued for deterministic timing, instant-on behavior from on-chip Flash configuration memory, and high I/O-count pin flexibility. As part of the MAX II family, the EPM1270T144A5N targets high-volume cost-sensitive applications where instant-on logic and zero-configuration-time boot are essential.

Key features include 116 user I/Os, 8 Kbits of embedded Flash user memory, JTAG (IEEE 1149.1) and in-system programmability via the Altera/Intel Quartus toolchain, and a wide -40C to +125C operating temperature range. The automotive-grade temperature suffix ("A5") indicates this part is rated for AEC-Q100-style harsh-environment use, though formal automotive qualification status should be confirmed against the latest Intel product folder.

The EPM1270T144A5N uses a non-volatile Flash-based Look-Up Table (LUT) architecture with a global low-skew interconnect, providing predictable pin-to-pin delays that simplify multi-board timing closure. Compared with SRAM-based FPGAs it requires no external boot PROM and powers up ready-to-run, which is a decisive advantage in industrial control and automotive subsystem designs.

Typical applications include I/O expansion and bus bridging, power-sequencing and reset-distribution logic, LED and display control, industrial sensor aggregation, automotive body and infotainment glue logic, and consumer electronics control planes. Designers should allocate JTAG pins (TCK/TMS/TDI/TDO) and decoupling capacitors per the MAX II handbook, and verify Quartus II/Quartus Prime support for the EPM1270 device symbol before commit.

Applications typiques

EPM1270T144A5N convient pour 6 applications: Industrial Bus Bridging and I/O Expansion, Automotive Body and Cluster Electronics, Power Sequencing and Reset Distribution, LED Display and Lighting Control, Industrial Sensor Aggregation, Consumer Electronics Control Plane.

🏭

Industrial Bus Bridging and I/O Expansion

The EPM1270T144A5N's 116 user I/Os and 6.2 ns tpd make it an ideal bus bridge between mismatched parallel buses in industrial PLCs and motor drives. Its 2.375-3.6 V single-supply range lets it interface directly to 3.3 V LVCMOS microcontrollers without level shifters, while its non-volatile Flash storage means instant-on configuration - critical when the PLC must respond within microseconds of power-up. The wide -40C to +125C operating range supports factory-floor cabinets and outdoor enclosures alike. Designers typically instantiate the CPLD as a 16-bit GPIO expander behind a SPI/parallel MCU, freeing MCU pins for higher-priority functions.

Automotive Body and Cluster Electronics

The "A" temperature grade and automotive part marking of the EPM1270T144A5N suit it for body controllers, instrument clusters, and infotainment glue logic. The 980 macro cells comfortably absorb typical 50-150 state-machine designs for turn-signal multiplexing, lighting control, and CAN/LIN message routing. The deterministic 6.2 ns tpd ensures timing closure without lengthy P&R iterations, and the non-volatile boot means the cluster powers up synchronously with the rest of the dashboard - no flash loaders, no boot screens. Engineers should still validate AEC-Q100 PPAP documentation with Intel for full automotive design-in.

Power Sequencing and Reset Distribution

The EPM1270T144A5N excels as a power-sequencer in multi-rail systems (FPGA + DDR + analog), where up to 116 I/Os let it control dozens of enable lines, PG signals, and watchdog timers from a single chip. Its 6.2 ns tpd supports sequencing of rails switching within 10-20 ns of each other - important for hot-swap and PoE applications. The non-volatile Flash boot is deterministic at power-up, eliminating the risk of an FPGA downstream loading before its rails are stable. Designers commonly pair the CPLD with a 3.3 V supervisor and DC-DC converters to build a complete sequencing subsystem in <2 cm^2 of board space.

LED Display and Lighting Control

The EPM1270T144A5N's high I/O count and fast tpd suit it for driving large LED matrices, architectural lighting, and signage controllers. With 116 outputs, it can drive 24x RGB LED matrices directly via Charlieplexing or scan-row architectures, refreshing at >1 kHz to eliminate flicker. The non-volatile boot means animated displays come up instantly without flash loaders, and the -40C to +125C range covers outdoor signage and industrial lighting. The CPLD's deterministic timing simplifies PWM generation for accurate color mixing, while its low power (typ. <100 mA) suits solar-powered installations.

Industrial Sensor Aggregation

Industrial sensor hubs aggregate dozens of digital sensors (temperature, pressure, flow) via I2C/SPI/UART and expose a single high-speed uplink. The EPM1270T144A5N's 116 I/Os comfortably multiplex 20-30 sensor buses, while its 6.2 ns tpd supports real-time aggregation at >10 MHz aggregate throughput. The 2.375-3.6 V supply range interfaces directly to 3.3 V sensor ICs, and the -40C to +125C range survives factory and outdoor environments. Engineers commonly use the CPLD as an I2C-to-SPI bridge, address translator, or sensor-data packetizer feeding an Ethernet or CAN uplink.

Consumer Electronics Control Plane

The EPM1270T144A5N serves as a cost-effective control plane in consumer devices (set-top boxes, IoT gateways, printers), handling button de-bouncing, IR receiver decoding, LED status indication, and simple state machines. With 980 macro cells, designers can absorb 5-10k gates of control logic in a USD 35 part (qty 1000), cheaper than a small FPGA. Its 144-TQFP package is hand-solderable for prototypes, while the Quartus II/Quartus Prime free toolchain supports the EPM1270 family without license fees. The non-volatile boot means consumer devices power up into known states instantly, improving UX.

What is the maximum propagation delay of the EPM1270T144A5N?
The EPM1270T144A5N has a maximum pin-to-pin propagation delay (tpd) of 6.2 ns, measured from input pin to output pin at room temperature with nominal 3.3 V supply. This fast deterministic delay is the key reason designers choose MAX II CPLDs over SRAM-based FPGAs when timing closure must be guaranteed without P&R iterations. Source: Intel MAX II Device Handbook.
How many user I/Os does the EPM1270T144A5N provide?
The EPM1270T144A5N exposes 116 user I/Os in the 144-pin TQFP package, leaving the remaining pins for JTAG (TCK/TMS/TDI/TDO), power (VCCINT/VCCIO), and ground. 116 high-performance I/Os is unusually high for a CPLD in this package size, and is the headline reason the MAX II EPM1270 is widely used for bus-bridging and I/O-expansion tasks in industrial designs.
What supply voltages does the EPM1270T144A5N require?
The EPM1270T144A5N operates from a single 2.375 V to 3.6 V supply rail, internally regulated to the 2.5 V or 3.3 V core domain. This wide supply range lets you interface directly to 3.3 V LVCMOS/LVTTL logic without external level shifters, simplifying board design. Always place 0.1 uF decoupling caps within 2-3 mm of every VCC pin per the MAX II handbook guidelines.
Where can I download the EPM1270T144A5N datasheet PDF?
The official datasheet for the EPM1270T144A5N is published in the MAX II Device Handbook, available at intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max2/max2_mii5v1.pdf. The handbook contains DC/AC specs, JTAG programming flow, thermal data, and Quartus II/Quartus Prime pin assignment guidelines for the EPM1270 family. Always check the latest revision on intel.com before committing to a design.
Where to buy EPM1270T144A5N online and what is the price?
As of 2026-09-12, the EPM1270T144A5N is in stock at authorized distributors including DigiKey (544-3519-ND), Mouser, Arrow, and Heisener, with a unit price around USD 54.89 at qty 1 dropping to USD 32.94 at qty 1000. Octopart shows live stock across 2+ distributors; for guaranteed authentic stock, order from franchised distributors or via XAIPART with traceable paperwork.
What is the lead time for EPM1270T144A5N?
As of 2026-09-12, the EPM1270T144A5N ships from distributor stock with lead times of typically 3-5 business days for small quantities (e.g. Heisener quotes immediate ship, delivery Mar 4-Mar 9). For 1000+ piece orders, lead time is 4-8 weeks depending on factory backlog at Intel. Authorized distributors (DigiKey, Mouser, Arrow) usually hold 5000-in stock at any time.
EPM1270T144A5N vs EPM1270T144C5N - which is better for industrial use?
The EPM1270T144A5N carries the "A" (automotive / -40C to +125C TJ) temperature grade, while the EPM1270T144C5N carries the "C" (commercial, 0C to +85C) grade. For industrial applications operating between -40C and +85C ambient, the A5N variant is the correct choice because of its wider thermal envelope and AEC-Q100-style automotive testing. The C5N is only acceptable in climate-controlled indoor environments. Both share the 144-TQFP package and pinout.
EPM1270T144A5N vs EPM1270T144C4N - what is the difference?
The EPM1270T144A5N has a maximum tpd of 6.2 ns (speed grade -5) and operates up to 125C, while the EPM1270T144C4N has a faster tpd of around 4.5 ns (speed grade -4) but is limited to 0C-85C (commercial grade). For glue-logic at typical 10-100 MHz, the A5N is the safer pick because of its temperature range; the C4N is preferred when raw speed matters more than thermal envelope. Both share the 144-TQFP footprint.
What is the best drop-in replacement for EPM1270T144A5N?
The best drop-in replacement for EPM1270T144A5N is the EPM1270T144C5N if the application does not need the automotive -40C to +125C temperature grade - same 144-TQFP package, same 980 macro cells, same JTAG/ISP, but slightly different speed grade. For an exact same-spec drop-in, the EPM1270T144I5N (industrial grade) is functionally identical with 116 I/Os. Both can be soldered onto the existing 144-TQFP land pattern without PCB changes.
When should I choose EPM1270T144A5N over a small FPGA?
Choose the EPM1270T144A5N when you need instant-on deterministic logic (Flash-based, no boot PROM), 116+ I/Os, simple design flow (Quartus schematic/VHDL), and per-unit cost below USD 50 at qty 1000. For designs requiring more than ~2000 logic elements, soft-core processors, or DSP blocks, an Intel Cyclone or Lattice ECP5 FPGA is a better fit. The EPM1270 excels as bus-bridging glue logic, reset sequencer, and I/O expander in industrial/automotive systems.
Is EPM1270T144A5N suitable for automotive AEC-Q100 designs?
The EPM1270T144A5N carries the "A" automotive temperature grade with -40C to +125C operating range, making it suitable for many body-electronics, infotainment, and cluster applications. However, for full AEC-Q100 qualification documentation (PPAP, stress test reports), engineers should verify the exact part number on the Intel MAX II automotive product list - some "A" grades are graded but not fully AEC-Q100-certified. Confirm with your Intel FAE before AEC-Q100 design-in.
What is the best Lattice equivalent for EPM1270T144A5N?
The closest Lattice Semiconductor drop-in alternative for EPM1270T144A5N is the ispMACH 4000 family LC4256ZE-7TN144C in the same 144-pin TQFP footprint, with 256 macro cells. While not an exact macro-cell-count match (EPM1270 has 980 vs LC4256's 256), the LC4256ZE shares the same 144-TQFP land pattern and JTAG/ISP programming model, allowing PCB reuse. For a closer macro-cell fit, Lattice's MachXO2 LCMXO2-4000HC-4TG144C is recommended but is in a different logic family (FPGA, not CPLD).
Is EPM1270T144A5N in stock?
As of 2026-09-12, the EPM1270T144A5N is in stock at DigiKey (544-3519-ND), Mouser, Arrow, and Heisener, with Heisener reporting 6384 pieces available. Octopart lists live stock across 2+ distributors.

The EPM1270T144A5N has an "A" (automotive, -40C to +125C TJ) temperature grade, while the EPM1270T144I5N has an "I" (industrial, -40C to +100C TJ typically) grade. Both share the same 144-TQFP package, 980 macro cells, 116 I/Os, and 6.2 ns tpd specification. The A5N is preferred for under-hood, body, and cluster modules; the I5N is preferred for industrial control cabinets and factory automation. For most applications either grade works, but the A5N offers wider margin.

Guide de sélection

Choose the EPM1270T144A5N when you need an automotive-grade MAX II CPLD with 980 macro cells and 116 I/Os in a 144-TQFP package for under-hood, body, or outdoor applications operating between -40C and +125C. Choose the EPM1270T144C5N for commercial-temperature designs where cost matters more than thermal margin. Choose the EPM1270T144I5N for industrial control cabinets where -40C to +100C is sufficient. Choose the EPM1270T144C4N or C3N when your design is speed-limited at the expense of temperature range. All four parts share the same 144-TQFP land pattern, enabling PCB layout reuse. For designs needing more than ~2000 logic elements or soft-core processors, migrate to an Intel Cyclone FPGA.

Principaux différenciateurs

  • Automotive temperature grade with same 144-TQFP footprint (vs EPM1270T144C5N)
  • Industrial grade with widest thermal margin in same package (vs EPM1270T144I5N)
  • Slower but thermally wider than faster speed grades (vs EPM1270T144C3N)

Notes de conception

Estimated: The EPM1270T144A5N draws approximately 30-50 mA quiescent current at 3.3 V (1-2 mA per macro cell cluster when switching lightly) per typical MAX II characterization. Place one 0.1 uF ceramic decoupling capacitor within 2-3 mm of each VCCINT and VCCIO pin, and add a single 10 uF bulk tantalum or ceramic cap near the package. The MAX II handbook recommends separating VCCINT and VCCIO planes only if your system has mixed-voltage I/O - otherwise a single 3.3 V plane is acceptable.

Estimated: The 144-TQFP package has 0.5 mm pitch and 20x20 mm body size, with lead length about 1.5 mm. For hand-prototyping, use a fine-tip soldering iron (or hot air) and pre-tin the pads. For production, follow JEDEC J-STD-020 MSL-3 handling (peak reflow 260C, <30 sec above 250C). Keep JTAG signals (TCK/TMS/TDI/TDO) routed as a 4-wire bus away from switching I/O traces to avoid programming glitches; add 10 kohm pull-ups on TCK/TMS/TDI and 10 kohm pull-down on TDO if the JTAG header is removable.

Common pitfalls when designing with the EPM1270T144A5N include: (1) forgetting that JTAG pins TCK/TMS/TDI/TDO cannot be used as general-purpose I/O without disabling JTAG in the Quartus device options - check the device pinout file before commit; (2) assuming all 116 I/O pins support every I/O standard - VCCIO groups restrict LVDS/3.3 V LVCMOS to specific banks; (3) using the A5N grade for non-automotive applications wastes cost - choose C5N or I5N for commercial/industrial designs; (4) not assigning the CONFIG_DONE and nCONFIG pins if using the optional dual-boot configuration mode.
