EPM570GT144I5 - MAX II CPLD, 570 LE, 144-TQFP, Industrial | Intel

The Intel (formerly Altera) EPM570GT144I5 is a low-power MAX II Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements, 440 macro cells, and 116 user I/Os in a 144-pin TQFP (20x20 mm) package. Operating from a single 1.71 V to 1.89 V internal core supply, the device is fabricated on a 0.18 µm process and supports in-system programmability via JTAG. According to the Altera MAX II Device Handbook, the device delivers non-volatile configuration with instant-on behavior in under 200 µs, eliminating the external boot PROM required by SRAM FPGAs. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that bridges the gap between discrete glue logic (74-series gates) and high-density FPGAs. CPLDs use a classic AND-OR (PLA-style) architecture with non-volatile flash configuration memory, giving them instant-on behavior and deterministic timing. In the broader taxonomy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. MAX II CPLDs are positioned as low-power, low-cost glue-logic replacements for ASICs, microcontrollers, and small FPGAs. Key features include a maximum pin-to-pin propagation delay (tPD) of 5.4 ns at industrial temperature, an internal oscillator, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels, and 8 Kbits of user flash memory. The 144-TQFP package provides a thermal resistance of approximately 26 C/W (theta_JA) and supports commercial (0 °C to +85 °C) operation with the I5 industrial-grade speed/temperature suffix. The MAX II architecture uses a uniform Logic Element Array (LEA) of 570 Logic Elements, each containing a 4-input look-up table and a programmable flip-flop, fed by a global interconnect. The flash-based configuration is single-chip (no boot device) and supports live updates via JTAG or the built-in Altera programming interface. This makes the EPM570GT144I5 well-suited to applications requiring instant-on, deterministic timing, and small logic capacity with low standby power. Typical applications include I/O expansion and bus bridging in industrial controllers, LED display drivers, glue-logic replacement for legacy 74HC designs, power-sequencer controllers, and configuration watchdog logic. The 116 user I/Os are sufficient for mid-density parallel interfaces such as 16-bit data + control buses, LCD/LED matrix driving, and address decoding. The device is well suited to designs where instant-on behavior and low quiescent current are more important than raw logic density. When designing with the EPM570GT144I5, pay attention to supply decoupling (four 0.1 µF capacitors placed close to each VCCIO/GND pair is the recommended pattern from the MAX II handbook) and to JTAG signal integrity on long board traces. The internal core must be supplied separately from the I/O banks, but all rails can be derived from a single 3.3 V source through onboard regulation.

EPM570GT144I5N - 570 LE MAX II CPLD TQFP-144 | Intel

The Intel EPM570GT144I5N is a non-volatile, low-power MAX II Complex Programmable Logic Device (CPLD) delivering 570 Logic Elements (approximately 440 macrocells) in a 144-pin TQFP (GT144) package. It operates from a 1.8 V core supply with MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V interfaces, targets industrial temperature grade (-40C to +100C), and belongs to speed grade I5 (the fastest industrial grade). A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL splatter logic and high-density FPGAs. It is built from multiple macrocell Logic Array Blocks (LABs) interconnected by a global programmable interconnect matrix, retains configuration in on-chip flash, and provides deterministic, nanosecond-class pin-to-pin propagation delays. Within the broader taxonomy, a CPLD is a type of programmable logic device -> logic IC -> integrated circuit, frequently used as glue logic, I/O expansion, or interface bridging in micro-controller-based systems. Key features of the EPM570GT144I5N include 8 Kbits of on-chip User Flash Memory (UFM), MultiVolt core and I/O for mixed-voltage rails, instant-on non-volatile flash configuration, enhanced in-system programmability (ISP) via JTAG, and 116 user I/O pins (TQFP-144). The device is fabricated on a 6-layer-metal flash process and offers high I/O count, fast propagation delay, and reliable fitting versus alternative CPLD architectures. The MAX II architecture uses a Lookup Table (LUT)-based LAB array with non-volatile flash configuration cells, eliminating the external boot PROM required by SRAM-based FPGAs and providing instant-on behavior within microseconds of power-up. The MultiVolt I/O bank design lets a single 1.8 V core part directly interface with 1.5 V, 1.8 V, 2.5 V, and 3.3 V peripherals without external level shifters. Typical applications include industrial control glue logic, bus interface bridging (e.g., parallel-to-SPI, address latch decoding), power-up sequencing and reset distribution, I/O expansion for microcontrollers, and LED / 7-segment display multiplexing. The 116-user-I/O count is well suited to systems that need many general-purpose pins but lack the bulk of an FPGA. When designing with this part, reserve JTAG pins (TDI, TMS, TCK, TDO) for ISP programming and boundary-scan test; they cannot be repurposed as user I/O. For mixed-voltage designs, consult the I/O standard tables in the datasheet to select the correct VCCIO bank voltage; incorrect bank voltage is the most common EPM570 design error.

It features a 5.4 ns pin-to-pin logic delay and is housed in a 100-pin MBGA (Micro FineLine BGA) package with non-volatile on-chip flash configuration memory of 8 Kbits. The device supports instant-on, in-system programmability (ISP) and MultiVolt core operation across multiple I/O standards. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple PAL/GAL devices and large FPGAs in the programmable logic hierarchy. CPLDs typically contain multiple macrocell logic blocks with a centralized interconnect fabric, providing deterministic timing, instant-on behavior (no boot loader required), and high-drive I/O. The MAX II family, of which the EPM570M100C4N is a member, is widely used for I/O expansion, bus bridging, power-up sequencing, and glue-logic replacement in cost-sensitive industrial, consumer, and communications designs. The EPM570M100C4N integrates 440 macrocells, equivalent to 570 logic elements (LEs), and includes an embedded User Flash Memory (UFM) block of 8 Kbits for storing non-logic data such as serial numbers, calibration tables, or boot parameters. MultiVolt core support allows the device to interface with 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic levels without external level shifters. Enhanced in-system programmability via JTAG (IEEE 1149.1) enables field upgrades without removing the part from the board. Architecturally, the EPM570M100C4N uses a flash-based, non-volatile configuration cell that eliminates the need for an external boot PROM and provides instant-on operation in under 1 ms. The LAB (Logic Array Block) structure combined with a global routing pool delivers predictable, deterministic timing critical for asynchronous interface glue logic. Compared to the older MAX 7000 series, MAX II offers roughly 10x lower static power, higher logic density, and a smaller footprint in equivalent BGA packages. Typical applications for the EPM570M100C4N include 5 V to 3.3 V / 1.8 V bus bridging in legacy industrial backplanes, I/O expansion for microcontrollers and microprocessors that lack sufficient pins, power-up/power-down sequencing for multi-rail systems, LED driving and display control, motor-control timing logic, JTAG-based board-level configuration, and replacement of discrete 74-series glue logic in cost-sensitive designs. When designing with this device, observe the recommended decoupling scheme of 0.1 µF and 10 µF capacitors placed within 3 mm of each VCC pin and ensure the JTAG chain respects the device's TCK frequency limits. The 100-pin MBGA package requires PCB pads with proper microvia or via-in-pad technology for reliable assembly and reflow. This page synthesizes real-time distributor pricing, drop-in same-package MAX II alternatives, and practical design considerations not collected in a single datasheet document, helping engineers shorten sourcing, BOM validation, and PCB layout reviews.

EPM570M100C5N

EPM570M100C5N - 440 Macrocell MAX II CPLD, 100-MBGA | Intel

The Intel (formerly Altera) EPM570M100C5N is a non-volatile, instant-on Complex Programmable Logic Device (CPLD) from the MAX II family, housed in a 100-ball FineLine BGA (MBGA, 6x6 mm, 0.5 mm pitch) package. It delivers 440 macrocells (570 logic elements) of user-programmable logic, 76 user I/Os, an internal fMAX up to 201.1 MHz, and pin-to-pin propagation delay as fast as 5.4 ns. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of a PAL/GAL with the density and routability of a small FPGA. Within the broader hierarchy of programmable logic, CPLD sits between discrete 74-series glue logic and high-density FPGAs, providing deterministic timing, low standby power, and a single-chip solution for bus decoding, I/O expansion, and power-up control. The MAX II family specifically targets glue-logic replacement with MultiVolt I/O support, on-chip User Flash Memory (UFM), and JTAG-based in-system programmability. Key features of the EPM570M100C5N include 8 Kbits of UFM for non-volatile user data, MultiVolt I/O supporting 1.5V/1.8V/2.5V/3.3V interfaces, a 2.5V/3.3V core, JTAG (IEEE 1149.1) and ISP support, plus a commercial operating temperature grade (0C to +85C). The device is built on a 0.18 um, 6-layer-metal flash process and consumes standby current in the microamp range, suiting it to power-sensitive designs. Architecturally, MAX II uses a logic-element array with a continuous, non-segmented interconnect that delivers predictable, deterministic timing - critical for control applications such as address decoding, bus bridging, and reset distribution. The on-chip flash stores the configuration, so the device starts in a known state within microseconds of power-up, removing the external configuration memory required by SRAM-based FPGAs. Typical applications include bus interface bridging, I/O expansion for microcontrollers and ASSPs, address/command decoding in DDR memory subsystems, power-sequencer and reset-controller logic, peripheral glue-logic replacement, and protocol bridging (UART, SPI, I2C, parallel). The wide MultiVolt I/O makes it especially useful when bridging a 1.8V processor to 3.3V peripherals. When designing with the EPM570M100C5N, note that the 100-MBGA package requires a 4-layer PCB with microvia technology or a 6-layer stack-up for fan-out routing, plus proper thermal relief on the ball pads. All unused I/O pins should be configured as outputs driving a defined logic level to minimize quiescent current. This page synthesizes distributor pricing, drop-in alternatives within the EPM570 pin-compatible family, and practical PCB/glue-logic design notes that complement (rather than duplicate) the manufacturer datasheet.

EPM570M100I5N - 440 Macrocell CPLD, MAX II, 100-MBGA | Intel

The Intel (formerly Altera) EPM570M100I5N is a non-volatile, low-power MAX II Family Complex Programmable Logic Device (CPLD) with 440 macrocells, an internal fmax of 201.1 MHz, and a 5.4 ns pin-to-pin logic delay, housed in a 100-pin Micro FBGA (MBGA) package measuring 6 x 6 mm with 0.5 mm pitch. It provides 76 user I/Os, operates from 2.5 V/3.3 V core supply rails, and is built on a 0.18 µm CMOS process. The device integrates 8 Kbits of user flash memory for non-volatile configuration storage. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix, offering deterministic, single-chip operation with instant-on behavior. In the broader hierarchy, a CPLD sits between simple SPLDs (PAL/GAL) and FPGAs: it is a type of programmable logic device (PLD) -> semiconductor -> integrated circuit. Unlike SRAM-based FPGAs that require external boot memory, MAX II CPLDs configure themselves instantly from on-chip flash, making them ideal for system control, interface bridging, and power-sequencing glue logic. Key features include instant-on non-volatile architecture, 201.1 MHz maximum operating frequency, low power consumption due to the 0.18 µm process and standby modes, JTAG (IEEE 1149.1) and in-system programmability via JTAG, and a 4-Wire Serial Interface for user flash memory access. The I/O structure supports 3.3 V LVTTL/LVCMOS with multi-voltage capability through banked VCCIO rails. The device operates over the industrial temperature range of -40°C to +100°C (I5 grade). Architecture-wise, the EPM570M100I5N is organized into four Logic Array Blocks (LABs) of 110 macrocells each, interconnected by a MultiTrack interconnect that provides predictable timing regardless of routing density. The on-chip user flash is split into sectors accessible through the Serial Flash Interface (SFI), enabling user data storage without an external EEPROM. Designers benefit from Quartus II / Quartus Prime design software with full VHDL/Verilog/SystemVerilog synthesis. Typical applications include bus interface bridging (e.g., PCI-to-local bus glue logic), power-supply sequencing in telecom and industrial equipment, I/O expansion and address decoding for microcontrollers, peripheral control in embedded systems, LED display driving and panel control, and replacement of discrete 74-series logic. With instant-on operation and high drive strength, the EPM570M100I5N is widely used as system glue logic in cost-sensitive industrial, medical, and consumer designs. When designing with this part, always honor the banked I/O supply (VCCIO) constraint: each I/O bank has independent VCCIO that determines output voltage level, while VCCINT powers the core logic at 2.5 V. JTAG chain ordering must follow the BSDL file, and unused pins should be configured per the Quartus default pin assignments to avoid excessive inrush current during configuration.

The Intel (formerly Altera) EPM570M256C4N is a low-power, non-volatile Complex Programmable Logic Device (CPLD) from the MAX II family, featuring 440 Logic Elements (LEs) and 160 user I/Os in a 256-ball Micro FineLine BGA (MBGA) package. It operates from a 1.8 V core supply with 2.5 V / 3.3 V multi-voltage I/O support and offers instant-on (≤ 0.5 ms) configuration from on-chip Flash, eliminating the need for external boot PROMs in most designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/GAL architectures with modernized macro-cell-based logic blocks and a wide routing fabric. MAX II devices are positioned in the broader programmable logic taxonomy below FPGAs but above simple SPLDs: SPLD → CPLD → FPGA → SoC FPGA. CPLDs are typically used for I/O expansion, bus bridging, glue logic, power-sequencing, and configuration control where instant-on behavior, low static power, and simple tool flow matter more than raw LUT density. Key features of the EPM570M256C4N include 440 Logic Elements, 8 Kbits of user Flash memory (UFM), 160 maximum user I/Os, and 247.5 MHz internal performance. It supports in-system programmability via JTAG and is built on a 0.18 µm CMOS process. The 256-ball MBGA package enables high pin density on compact PCBs, making it suitable for space-constrained industrial designs requiring broad I/O access. The MAX II architecture uses a MultiVolt core, an enhanced routing matrix, and a per-macrocell look-up table combined with product-term logic, providing predictable timing and low power consumption (typically under 50 mW static). Compared with classic 5 V CPLDs, MAX II reduces dynamic I/O current and offers multi-voltage I/O standards including LVCMOS, LVTTL, and PCI at 2.5 V / 3.3 V. Typical applications include I/O expansion and bus bridging in industrial controllers, power-sequence and supervisory logic in telecom line cards, board-level glue logic for ASSP/ASIC-based designs, and configuration control of FPGAs via JTAG master / slave modes. Designers also use MAX II for LED driving, scan-chain muxing, and legacy bus translation where instant-on, single-chip solutions are required. When designing with this device, note that the 256-ball MBGA requires 4-layer PCB stack-ups with microvia or via-in-pad technology for reliable assembly. Decoupling must include 0.1 µF capacitors placed within 3 mm of every VCCIO/VCCINT pair, with a bulk 10 µF tantalum nearby. The JTAG chain should be designed for in-system programming without removing the device from the board.

Key features include 440 Logic Elements (LEs), 5.4 ns tPD, 201.1 MHz fMAX, MultiVolt core supporting 1.8 V/2.5 V/3.3 V interface voltages, JTAG IEEE 1149.1 boundary-scan, in-system programmability via JTAG, and a User Flash Memory block for on-die parameter storage. The 256-MBGA package provides 212 user I/O pins, enabling high-density bus bridging without external logic expansion. The device architecture combines a Look-Up Table (LUT) based Logic Element array, a fast continuous interconnect network, and MultiVolt I/O banks that let each pin operate at a different standard independently. Internal Flash stores both the configuration image and user data, eliminating the need for an external boot PROM and reducing board complexity for low-density logic consolidation. Typical applications include address decoding and bus-interface bridging in 32-bit and 64-bit microprocessor systems, I/O expansion and voltage-level translation between mismatched logic families, power-up sequencing controllers for multi-rail systems, peripheral glue logic in industrial controllers, and LED-display or scanner driving where deterministic timing and zero standby power are required. When designing with this part, observe the 256-ball MBGA PCB layout rules (1.0 mm ball pitch, microvia or via-in-pad recommended) and provide 1.8 V, 2.5 V, and 3.3 V supplies for core and I/O banks.

EPM570M256I5N - MAX II CPLD, 440 Macrocells, 256-MBGA | Intel

The Intel EPM570M256I5N is a non-volatile, flash-based MAX II family CPLD (Complex Programmable Logic Device) with 440 macrocells (570 logic elements) housed in a 256-ball MBGA package (11x11 mm). It features 160 user I/Os, a maximum propagation delay of 5.4 ns, and internal core voltage support at 2.5 V or 3.3 V. The device targets glue-logic, bus-bridging, and I/O-expansion applications where deterministic timing and instant-on non-volatility matter. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/GAL architecture with modern flash memory cells. The hierarchy is: logic cell -> macrocell -> logic array block (LAB) -> CPLD. CPLDs sit between discrete 74-series glue logic and FPGAs in terms of density and complexity, offering instant-on operation, single-chip non-volatile storage of the bitstream, and predictable pin-to-pin propagation delays that make them ideal for control-plane and interface-bridging roles. The EPM570M256I5N delivers 440 macrocells / 570 logic elements, supports up to 160 user I/Os at LVCMOS/LVTTL levels, and provides 5.4 ns tPD (fastest speed grade I5), measured through the MAX II MultiCore interconnect. It integrates 8 Kbits of user flash memory (UFM) block for storing parameter data, serial numbers, or firmware revisions alongside the configuration. Built on a 0.18 µm CMOS process, the device consumes substantially less static power than the legacy MAX 7000 series it replaced, while retaining the same Quartus II / Quartus Prime design flow and JTAG-based in-system programmability (ISP). Typical applications include bus-bridging between legacy microcontrollers and modern processors (e.g., 8-bit MCU to 32-bit ARM SoC), I/O expansion in industrial PLC backplanes, address decoding and chip-select generation in FPGA-based systems, and level shifting between mixed-voltage domains. The instant-on flash-based architecture suits power-sequenced designs and safety-critical boot paths where an SRAM-based FPGA cannot satisfy cold-start latency. When designing with this device, ensure your JTAG chain order is correct for ISP, leave at least 4 user I/Os unused as JTAG TDO/TMS/TCK/TDI to keep boundary-scan capability, and verify that the 1.8 V internal core is generated by the on-chip regulator - no external LDO is needed but decoupling must follow the Quartus II pin assignment tool's recommendations.

EPM570T10015 - MAX II CPLD, 570 LEs, TQFP-100 | Intel / Altera

The Intel / Altera EPM570T10015 is a member of the MAX II family of instant-on, non-volatile CPLDs based on a 0.18-µm process, integrating 570 logic elements (LEs) into a 100-pin TQFP (T100) package. It is rated for the industrial temperature range (-40 °C to +85 °C) and is intended as a glue-logic and I/O-expansion companion to microcontrollers, ASICs, and ASSPs. The 'T100' suffix indicates the 100-pin TQFP package, while '15' denotes a 15 ns pin-to-pin propagation delay (commercial/industrial speed grade). A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device containing multiple macro cells connected through a programmable interconnect array. CPLDs sit between discrete 74-series glue logic and FPGAs in the programmable logic hierarchy: they offer deterministic timing, instant-on configuration from on-chip flash, and are typically used for bus interfacing, power-up sequencing, and I/O expansion. MAX II parts are widely adopted as low-power, low-cost glue logic replacing dozens of discrete logic ICs. Key features of the EPM570T10015 include 570 logic elements, 8 Kbits of user flash memory, multi-volt I/O support (1.5 V / 1.8 V / 2.5 V / 3.3 V) on the same bank, and JTAG-based in-system programmability (IEEE 1149.1 / IEEE Std 1532). The non-volatile flash configuration enables instant-on operation within microseconds of power-up with no external boot PROM, and the device supports I/O standards including LVTTL, LVCMOS, PCI, and SSTL on a per-pin basis. Internally, the device is organized as 570 LEs arranged across 4 Logic Array Blocks (LABs), each containing 16 macro cells, plus a flash-based configuration memory and a MultiTrack interconnect. Quartus II / Quartus Prime provides synthesis, place-and-route, and timing analysis. Power consumption is dominated by static current (typically a few mA) plus dynamic current proportional to switching frequency and toggle rate; total power is well below that of comparable FPGAs, making MAX II ideal for always-on glue logic. Typical applications include industrial control I/O expansion, motor-control signal conditioning, peripheral bus bridging (e.g. SPI/I2C to parallel GPIO), power-sequencing and supervisory logic, and board-level glue logic for ASIC/ASSP replacement. The 100-pin TQFP package provides ample I/O for medium-density glue-logic tasks while keeping the PCB assembly process mainstream. When designing with this device, observe the I/O-bank voltage constraints - mixing 3.3 V and 1.8 V signals requires that they be assigned to different I/O banks. Always de-couple the VCCINT and VCCIO pins with 0.1 µF ceramic capacitors placed as close to the package as possible, and follow Altera's Quartus PowerPlay guidelines for toggle-rate estimation to size the decoupling network.

EPM570T100A5N - 570 LEs, 440 Macrocells, MAX II CPLD | Altera

The Altera EPM570T100A5N is a non-volatile, low-power MAX II Complex Programmable Logic Device (CPLD) delivering 570 logic elements, 440 macrocells, and 76 user I/O pins in a 100-pin TQFP package. Built on a 0.18 µm flash-based process, the part operates across 1.5 V to 3.3 V core supply rails with user I/O bank support from 1.5 V to 5.0 V for flexible mixed-voltage system bridging. The 'A5' speed grade provides 5.4 ns pin-to-pin logic delay and a maximum internal operating frequency near 304 MHz, suitable for glue logic, bus interfacing, and control-plane state machines. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PLA-style logic blocks (Logic Array Blocks, or LABs) on a single chip with a global interconnect matrix. CPLDs are positioned below FPGAs in cost and complexity but above simple PALs/GALs in density, and they retain their configuration without an external configuration memory. In the broader programmable logic taxonomy, CPLDs sit alongside FPGAs as programmable logic devices, both derived from programmable read-only memory technology, and serve as power-management companion logic, bus interfaces, and deterministic boot-time controllers. Key features include instant-on (no boot PROM required thanks to on-chip flash), 1.8 V internal core voltage, MultiVolt™ I/O supporting 1.5/1.8/2.5/3.3 V interfaces, JTAG-based IEEE 1149.1 in-system programmability, and a 4-wire JTAG chain for boundary-scan testing. The device also offers 8 Kbits of user flash memory (UFM) for storing parameters, serial numbers, or small configuration tables, plus a built-in oscillator that supports common asynchronous tasks without external clocks. Architecturally, the EPM570T100A5N combines a non-volatile flash configuration cell array with a deterministic logic fabric that delivers predictable, jitter-free timing well suited to control applications. Compared with SRAM-based FPGAs, MAX II CPLDs are immune to configuration-memory bit-flip events and require no external boot device, reducing BOM cost and PCB footprint. Typical applications include I/O expansion and voltage translation between 3.3 V MCUs and 5.0 V peripherals, power-sequencing logic for multi-rail systems, LED display refresh and multiplexing controllers, industrial bus bridges (SPI, I2C, UART), and FPGA/CPLD configuration-memory replacement. Designers favor MAX II for designs that need deterministic boot, low standby power, and minimal board area. When designing, allow sufficient decoupling on each VCCINT and VCCIO bank, and observe the I/O bank grouping rules from the Altera MAX II Device Handbook. Route JTAG signals (TCK, TMS, TDI, TDO) with short, parallel traces and a 4.7 kΩ pull-up on TCK. Avoid using the I/O banks above 3.3 V when the connected peripherals only need 3.3 V, to minimize EMI and simplify signal integrity.

EPM570T100C3

EPM570T100C3 - MAX II CPLD, 570 LEs, 100-TQFP | Intel / Altera

The Intel (formerly Altera) EPM570T100C3 is a member of the MAX II family of instant-on, non-volatile CPLDs based on a 0.18-µm 6-layer-metal flash process. The device provides 570 logic elements (equivalent to 440 macrocells), 8 Kbits of user flash memory (UFM), and a maximum operating frequency of 304 MHz. Housed in a 100-pin TQFP (14×14 mm) package, the part is specified for commercial temperature grade and supports MultiVolt core I/O operation at 2.5 V or 3.3 V internal rails with MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces. The 'C3' suffix denotes the commercial temperature range and the fastest speed grade available within the EPM570 density in the T100 package. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PLA-like macrocell blocks with a central interconnect matrix. CPLDs sit between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy: they offer deterministic timing, instant-on configuration from on-chip flash, and lower pin counts than FPGAs, making them well suited to glue logic, bus bridging, and power-up sequencing tasks. The MAX II family specifically targets low-power, low-cost applications where flash-based instant-on and high I/O counts are required. Key features include 76 user I/O pins, JTAG boundary-scan and in-system programmability (ISP) via IEEE 1149.1, MultiVolt I/O for mixed-voltage interfacing, a built-in user flash memory block, and an internal pull-up resistor network on each I/O. The T100 package provides vertical migration capability within the MAX II family, allowing EPM240, EPM570, EPM1270, and EPM2210 devices to share the same 100-pin footprint. The EPM570T100C3 implements a non-volatile flash configuration memory, so the device powers up fully operational in microseconds without external configuration ROM. The flash-based UFM block can store up to 8 Kbits of user data, accessible through dedicated JTAG or logic-array-driven interfaces, eliminating an external EEPROM in many designs. Typical applications include I/O expansion and voltage-level translation between 3.3 V and 1.8 V or 1.5 V buses, power-on sequencing controllers, peripheral glue logic for microcontrollers and ASICs, bus decoding for memory and address bus expansion, and LED / 7-segment display multiplexing. Industrial designs also use the UFM block for parameter storage in low-cost systems. When designing with this device, note that the C3 speed grade is the fastest bin available for EPM570T100; pin-compatible alternatives include slower speed grades (C4, C5) and industrial-temperature variants (I5N). Designers should reserve adequate ground pins and follow Altera's Quartus II power-decoupling guidelines (typically 0.1 µF + bulk decoupling) to maintain signal integrity at high toggle rates.

EPM570T100C3N

EPM570T100C3N - 440-Macrocell MAX II CPLD, 100-TQFP | Intel / Altera

The Intel (formerly Altera) EPM570T100C3N is a 440-macrocell CPLD from the MAX II family, housed in a 100-pin TQFP package with 76 user I/Os. Built on 0.18 µm Flash-based process technology, it delivers a 5.4 ns pin-to-pin logic delay and supports internal frequencies up to 304 MHz. The device operates from a 2.5 V or 3.3 V core supply with multi-voltage I/O support, making it compatible with both legacy 3.3 V logic and modern 1.5 V/1.8 V interfaces via its banked I/O architecture. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on, deterministic timing characteristics of traditional PAL/GAL architectures with modern macrocell density and in-system programmability. Within the broader hierarchy, a CPLD sits below an FPGA in logic density but above discrete 74-series glue logic, occupying the role of deterministic, low-latency logic glue for bus interface, power-sequencing, and protocol-bridging tasks. The MAX II family in particular replaced legacy EEPROM-based MAX devices with a Flash-based configuration cell, giving instant-on behavior without external boot memory. Key features of the EPM570T100C3N include 440 logic elements (LEs), 8 Kbits of user flash memory (UFM), 4 input pins per logic array block (LAB), 76 maximum user I/Os, JTAG/IEEE 1149.1 boundary-scan support, and an internal oscillator. The device supports in-system programmability via JTAG, allowing field upgrades without removing the part from the board. Its MultiVolt I/O core can interface with 1.5 V, 1.8 V, 2.5 V, and 3.3 V signals on a mixed-voltage bus without external level shifters. The MAX II architecture uses a Logic Array Block (LAB) matrix interconnected by a continuous row-and-column routing fabric. Each LAB contains 16 macrocells fed by a 36-input look-up table (LUT) chain and product-term allocation logic. The Flash configuration memory eliminates the configuration bitstream load step required by SRAM FPGAs, achieving less than 100 µs wake-up time from power-on. The 0.18 µm process provides the static power profile typically expected of a non-volatile CPLD, with Icc typical values in the low milliamp range at idle. Typical applications include bus interface bridging (e.g., I²C-to-parallel, SPI-to-GPIO glue), power-sequence and reset-controller logic, LED display scanning drivers, industrial control board glue logic, and I/O expansion for microcontrollers. Its 100-pin TQFP footprint also makes it a frequent choice for legacy board replacements where an obsolete 5 V CPLD must be swapped out for a 3.3 V part with identical pinout. When designing with the EPM570T100C3N, note that the C3 speed grade corresponds to a 5.4 ns tPD1 propagation delay; if your timing budget is tighter than 6 ns, consider a C4/C5 speed grade from the same MAX II family. The device is non-volatile and one-time-programmable after configuration, so plan your JTAG chain order and ISP sequencing carefully during board bring-up.

EPM570T100C4 - 570 LEs, 5.4ns CPLD | Intel (Altera) MAX II | TQFP-100

The Intel (Altera) EPM570T100C4 is a 570-logic-element MAX II family CPLD (Complex Programmable Logic Device) housed in a 100-pin TQFP (T100) package with 5.4 ns pin-to-pin propagation delay and commercial operating temperature grade. The device integrates 440 macrocells, 8 Kbits of user flash memory, and 4.4 Mbits of general-purpose SRAM in a non-volatile, instant-on architecture. A CPLD (Complex Programmable Logic Device) is a non-volatile, reprogrammable digital logic IC that combines the deterministic timing of PAL/GAL architecture with modern flash-backed configuration. CPLDs sit in the broader taxonomy of programmable logic: glue-logic IC -> programmable logic device -> CPLD/FPGA -> silicon in the wider semiconductor hierarchy. Unlike FPGAs, which are RAM-based and require a configuration bitstream at every power-up, MAX II CPLDs store their configuration in on-chip flash, providing instant-on behavior at sub-100 microsecond times with zero external boot memory. Key features include a 3.3V core / 1.8V internal supply, MultiVolt I/O supporting 1.5V, 1.8V, 2.5V, and 3.3V interfacing on every I/O bank, 80 user I/O pins (TQFP-100), in-system programmability via JTAG (IEEE 1149.1), and a built-in oscillator for free-running or timer applications. The 5.4 ns tPD makes the EPM570T100C4 one of the fastest members of the MAX II family. The MAX II architecture uses a Logic Array Block (LAB) topology with 16 macrocells per LAB, a Programmable Interconnect Matrix (PIA), and per-macrocell registers with product-term logic. The on-chip user flash supports ISP (in-system programming) without external boot PROMs, simplifying board layout. Designers can use Quartus II / Intel Quartus Prime Web Edition for synthesis and fitting. Typical applications include bus-bridging glue logic, I/O expansion and voltage-level translation between 1.8V/2.5V/3.3V domains, address decoding and wait-state generation for microprocessors, configuration control for power sequencers, and LED / 7-segment display multiplexing. The wide MultiVolt I/O support is particularly valuable in mixed-voltage designs where 3.3V ASICs must interface to legacy 5V peripherals. When designing with the EPM570T100C4, ensure all four JTAG pins (TCK, TMS, TDI, TDO) are routed cleanly to a JTAG header for in-system programming. Place 0.1 uF decoupling capacitors near every VCCIO/VCCINT pin pair and provide a ground plane beneath the TQFP-100 thermal pad (exposed pad is not present on TQFP-100, but the central die flag should still tie to ground). The EPM570T100C4 is pin-compatible with the EPM570T100C3, C5, and A5 speed/temperature grades within the same T100 footprint, enabling easy migration.

Built on a 0.18 µm non-volatile flash process, it offers up to 76 user I/O, 247.5 MHz internal performance, and 5.4 ns pin-to-pin propagation delay, providing instant-on non-volatile configuration with single-chip glue-logic density well above legacy 5V CPLDs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single die with a global interconnect fabric. It sits in the programmable logic hierarchy between simple SPLDs (like GAL/PAL) and high-density FPGAs (like MAX 10 or Cyclone), making it ideal for I/O expansion, bus bridging, power-sequencing logic, and high-drive control where deterministic timing and instant-on boot are mandatory. The MAX II family specifically targets low-power, low-cost glue-logic replacement with on-chip flash storage that eliminates an external configuration PROM. Key features include 8 Kbits of user flash memory, an on-chip voltage regulator (single 3.3 V supply with internal generation of 1.8 V core), JTAG-based IEEE 1149.1 in-system programmability, 4-input look-up tables, and a MultiVolt I/O bank that supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces on the same die. The flash-based configuration memory removes the boot-delay penalty of SRAM FPGAs and is fully re-programmable in-circuit. Technically, the EPM570T100C4N implements a Logic Array Block (LAB) architecture of 570 LEs distributed across 19 LABs, with each macrocell containing a programmable register, product-term logic, and I/O control. The non-volatile flash cell array achieves zero boot latency, enabling the device to drive outputs within microseconds of power-up. The 100-pin TQFP (T4 suffix = commercial 0 °C to 85 °C, speed grade 4 = 5.4 ns tpd) variant exposes 76 user I/Os and is footprint-compatible with EPM570T100C3N/C5N speed and density siblings. Typical applications include I/O expansion and bus bridging in industrial controllers, power-sequencing and supervisory logic in networking equipment, glue logic in telecom backplanes, motor-control and LED-driving interfaces, and legacy 5V CPLD replacement in telecom/medical designs. The instant-on non-volatile configuration is particularly valued in deterministic boot systems such as automotive clusters, building automation, and safety-critical industrial controls. Design considerations include placing the 0.1 µF + 1 µF decoupling capacitors as close as possible to every VCCINT/VCCIO pin pair, providing a clean 3.3 V rail (the internal regulator rejects to 1.8 V core), and verifying the MultiVolt bank voltage (VCCIO) matches the driven interface before any configuration bitstream is loaded. Designers should also confirm the 100-pin TQFP thermal envelope supports their continuous-junction loading before relying on it in enclosed industrial housings.

EPM570T100C5RR - MAX II CPLD, 570 LEs, 100-TQFP | Intel

The Intel (formerly Altera) EPM570T100C5RR is a MAX II family Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements (LEs), 440 macro cells, and 201.1 MHz maximum operating frequency, fabricated on a 0.18 µm CMOS process and supplied in a 100-pin TQFP package. The part operates from a 2.5 V / 3.3 V core supply and targets low-power, instant-on glue-logic applications. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash-based programmable logic device positioned between discrete glue logic (74-series gates) and small FPGAs. Compared with discrete logic, a CPLD provides deterministic timing, parallel processing of multiple I/O events, and a single-chip implementation that reduces board area and BOM cost. In the broader hierarchy, CPLDs sit within programmable logic devices (PLDs) alongside FPGAs, with MAX II occupying the low-power, low-density, instant-on tier. Key features of the EPM570T100C5RR include 8.7 ns pin-to-pin logic delay, 100 user I/O pins, an internal flash configuration memory that eliminates external boot PROM, in-system programmability via JTAG, and a 1.8 V core on 2.5 V / 3.3 V I/O. The architecture delivers an instant-on capability typical of MAX II devices, allowing logic to be active within microseconds of power-up — a notable advantage over SRAM-based FPGAs that require configuration loading. Technically, the EPM570T100C5RR organizes its 570 LEs into four Logic Array Blocks (LABs) interconnected by a MultiTrack interconnect fabric. Each LE contains a four-input LUT, a programmable register, and a carry chain, supporting combinational and registered logic with deterministic propagation delays ideal for bus decoding, state-machine control, and interface bridging.

EPM570T100I5 - 570 LEs MAX II CPLD, 5.4ns TQFP-100 | Altera

The Altera (now Intel) EPM570T100I5 is a non-volatile, instant-on Complex Programmable Logic Device (CPLD) from the MAX II family, delivering 570 logic elements (440 macrocells) in a 100-pin TQFP package with 5.4 ns pin-to-pin logic delay and an industrial -40C to +100C operating temperature range. It is fabricated on a 0.18-micron, 6-layer-metal flash process and integrates 8 Kbits of user-accessible Flash memory (UFM) on-chip, removing the need for a separate boot PROM in most designs. Background: A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PLDs and high-density FPGAs in the programmable logic hierarchy. MAX II CPLDs use a flash-based architecture that holds the configuration in the same cells used for logic - hence "instant-on," since the device becomes operational within microseconds of power-up rather than requiring an external boot sequence. They are widely used as glue logic, bus bridges, interface controllers, and state machines where deterministic timing, low power, and non-volatility outweigh the need for very high gate counts. Key features of the EPM570T100I5 include 76 user I/Os, 5.4 ns tPD (pin-to-pin) propagation delay, a MultiVolt core supporting 1.8V/2.5V/3.3V I/O standards, in-system programmability via JTAG (IEEE Std. 1149.1), and on-chip user flash memory for storing constants, serial numbers, or boot parameters. The 100-pin TQFP (14x14x1 mm) package offers a low-profile footprint with gull-wing leads, suitable for reflow assembly on standard FR-4 PCBs. The MAX II architecture pairs a Logic Array Block (LAB) fabric with a Flash-based Configuration Flash Memory (CFM) and a User Flash Memory (UFM) block. This dual use of flash cells for both configuration and user storage is unique to MAX II and contributes to its very low standby current (typically <2 mA) compared to SRAM-based FPGAs. Typical applications include I/O expansion and bus bridging in industrial controllers, glue logic in telecom base-station line cards, configuration control in portable medical devices, state-machine replacement of discrete logic, and address decoding in microprocessor-based systems where non-volatile instant-on behavior is required. When designing with the EPM570T100I5, observe the recommended decoupling scheme (0.1 uF on each VCCIO/VCCINT pin pair), respect the 3.3V core supply, and use the Quartus II / Quartus Prime toolchain for synthesis, fitting, and JTAG programming. Pin assignments must obey the MAX II TQFP-100 pinout; vertical migration within the same package is supported to EPM1270 and EPM2210 densities.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks with a central interconnect matrix, providing deterministic timing, glue-logic integration, and instant-on behavior. The MAX II family sits in the broader taxonomy of programmable logic: CPLD -> programmable logic -> digital logic IC -> semiconductor. CPLDs differ from FPGAs by offering non-volatile configuration, predictable pin-to-pin propagation delays, and lower static current consumption, making them ideal for boot/control plane functions rather than data-path acceleration. Key features include 570 logic elements, 440 macrocells, up to 76 user I/Os, an 8-Kbit internal user flash block, JTAG (IEEE 1149.1) and in-system programmability, and MultiVolt I/O that supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels from a single supply domain. Industrial temperature grade (-40C to +100C junction) and surface-mount TQFP-100 packaging suit it for harsh-environment designs. The device uses a non-volatile flash-based configuration cell array that eliminates the external boot PROM required by older SRAM-based CPLDs, reducing board area and BOM cost. The LAB (Logic Array Block) architecture connects 10 LEs per block through a fast interconnect, providing deterministic tPD propagation delays suitable for asynchronous and decoded-glue logic. Typical applications include I/O expansion and bus bridging in industrial control boards, HVAC and appliance controllers, LED display multiplexing, and power-sequencing logic in telecom/networking line cards. Designers choose the EPM570T100I5N when they need deterministic timing, instant-on behavior, and moderate logic density without FPGA cost. When designing with the EPM570T100I5N, place 0.1 uF decoupling capacitors adjacent to every VCCINT and VCCIO pin and respect the 100-pin TQFP thermal pad layout for multi-layer boards. Quartus II / Quartus Prime design software is required for synthesis, fitting, and JTAG programming.

EPM570T144-5

EPM570T144-5 - MAX II CPLD 570 LE, 144-pin TQFP | Altera

The Altera (now Intel) EPM570T144-5 is a member of the MAX II family of instant-on, non-volatile Complex Programmable Logic Devices (CPLDs) fabricated on a 0.18-µm process and packaged in a 144-pin Thin Quad Flat Pack (TQFP). It integrates 570 logic elements, 440 macrocells-equivalent Look-Up Table (LUT) capacity and 8 Kbits of user-accessible Flash memory into a low-power, single-chip glue-logic platform aimed at bus bridging, I/O expansion and power-sequencing tasks. A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic device positioned hierarchically between discrete glue logic (74-series TTL/CMOS) and larger FPGAs. CPLDs deliver deterministic propagation delay, predictable pin-to-pin timing and battery-free configuration retention, making them ideal as interface bridges, address decoders, configuration controllers and machine-state controllers in systems built around microprocessors, microcontrollers or ASSPs. MAX II is Altera's lowest-cost CPLD family and the EPM570 sits at the top of that family's density ladder. Key features of the EPM570T144-5 include 570 logic elements, 4 user I/O banks with MultiVolt I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V), a 116-user-I/O count in the TQFP-144 footprint, on-chip user Flash memory (UFM) block, an in-system programmability (ISP) interface via JTAG, and an internal oscillator. The "-5" speed grade offers a tPD1 of approximately 5.0 ns, supporting designs clocked above 100 MHz internally and 200 MHz via dedicated clock networks, while commercial and industrial temperature grades provide operating range flexibility. Architecturally the EPM570 uses a non-volatile Flash configuration cell to retain the bitstream without external boot memory. The logic-array-blocks (LABs) are interconnected through a continuous MultiTrack interconnect, and routing is software-managed by the Quartus II / Quartus Prime toolchain. This architecture delivers instant-on operation: the device is functional within microseconds of power-up, eliminating the configuration-wait window typical of SRAM-based FPGAs. Typical applications include 3.3 V / 2.5 V / 1.8 V bus interface bridging, glue logic for microprocessors (8051, ARM Cortex-M, PowerPC), I/O expansion for FPGAs and ASICs, address decoding and chip-select generation, LED driving, configuration watchdog and reset sequencing, and industrial control / portable / power-management designs where instant-on behaviour is essential. When designing with the EPM570T144-5, ensure each VCCIO bank is decoupled with 0.1 µF and 10 µF capacitors placed close to the supply pins. The MultiVolt core allows the VCCINT supply to be powered at 3.3 V or 2.5 V while individual I/O banks interface to lower-voltage rails. JTAG programming pins (TCK, TMS, TDI, TDO) must be accessible for in-system updates; pull-ups on TCK, TMS and TDI are recommended per Altera's guidelines. This page consolidates distributor stock and pricing for the EPM570T144-5, drop-in compatible alternatives from the same MAX II family and competitor CPLD lines, and practical design notes that go beyond the manufacturer datasheet.

Maximum pin-to-pin propagation delay is 5.4 ns, making it well suited for high-speed interface bridging and protocol conversion tasks. Multi-voltage I/O supports interfacing to 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters. Typical applications include bus interface bridging (e.g., PCI to local bus, microcontroller to parallel port), power-up and power-rail sequencing in multi-supply systems, address decoding and chip-select generation, I/O expansion for microcontrollers and ASSPs, LED display driving, and protocol glue logic in industrial controllers, telecom line cards, and automotive body modules. The automotive temperature grade (denoted by the 'A' suffix) supports -40 °C to +125 °C operation. Designers should plan for I/O bank grouping to keep voltages compatible on shared banks, and provide adequate decoupling (one 0.1 µF per VCCIO bank is recommended). Quartus II or Quartus Prime design software is required for HDL entry, synthesis, fitting, and programming via the JTAG port using a USB-Blaster or compatible cable.

The Intel EPM570T144C3 is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs), delivering 440 Logic Elements (LEs) in a 144-pin TQFP package with a 5.4 ns pin-to-pin propagation delay. It is built on a 0.18 µm non-volatile flash process that provides instant-on configuration, eliminating the external configuration memory required by SRAM-based FPGAs. The device operates from a 2.5 V/3.3 V mixed-voltage core with multi-voltage I/O support. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the architecture of PAL/GAL with macro-cell arrays. It belongs to the broader category of programmable logic devices (PLDs), which sit alongside FPGAs as alternatives to fixed-function ASICs for glue logic, interface bridging, and state-machine implementation. CPLDs are characterized by instant-on behavior, deterministic timing, and high fan-in macrocells, making them ideal for control-plane applications. Key features of the EPM570T144C3 include 440 Logic Elements distributed across 8 Logic Array Blocks, 160 user I/O pins, and 4.0 Kbits of user flash memory. The device supports in-system programmability (ISP) via IEEE 1149.1 JTAG, MultiVolt I/O for interfacing between 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains, and operates over a commercial temperature range of 0 °C to +85 °C. The C3 speed grade provides a 5.4 ns tPD1 timing budget for high-speed control applications. Architecturally, the EPM570T144C3 uses a non-volatile flash-based lookup table structure within each Logic Element, providing single-chip functionality without a separate boot PROM. The MultiVolt core and I/O allow mixed-voltage system integration, while the JTAG interface supports boundary-scan test and on-board reconfiguration in production environments. Typical applications include bus interface bridging, power-up sequencing for multi-rail systems, I/O expansion and decoding logic, LED display drivers, and glue-logic replacement for discrete 74-series TTL. The wide I/O count and instant-on nature also suit industrial control and motor-drive front-end logic. When designing with this part, ensure that the Quartus II or Intel Quartus Prime toolchain is used for synthesis and fitting; design files compiled for the MAX II device family are required. Decoupling capacitors should be placed close to all VCCINT and VCCIO pins.

EPM570T144C3N - 570 LEs MAX II CPLD, TQFP-144 | Altera/Intel
EPM570T144C3N

EPM570T144C3N - 570 LEs MAX II CPLD, TQFP-144 | Altera/Intel

The Altera (now Intel) EPM570T144C3N is a member of the MAX II family of instant-on, non-volatile Complex Programmable Logic Devices (CPLDs) built on a 0.18-µm, 6-layer-metal flash process. It delivers 570 logic elements (440 typical macrocells) and 116 user I/Os in a 144-pin TQFP package with a 3.3V core supply, a maximum propagation delay of 5.4 ns, and a maximum operating frequency around 300 MHz. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single chip, interconnected by a programmable switch matrix. In the system hierarchy it sits below an FPGA and above a discrete logic array: it is used for glue logic, bus interfacing, power-up sequencing, and small state-machine functions where instant-on (no boot PROM needed), deterministic timing, and high I/O count matter more than raw density. MAX II devices add an 8-Kbit User Flash Memory (UFM) block and MultiVolt I/O, making them suitable for I/O bridging across mixed-voltage rails. Key features of the EPM570T144C3N include 8 Kbits of embedded UFM, in-system programmability through the standard IEEE 1149.1 JTAG interface, MultiVolt core supporting 3.3V operation, and a Schmitt-trigger input option on every I/O for noisy environments. The device supports LVCMOS, LVTTL, PCI, SSTL, and other I/O standards, and offers pull-up resistors that can be enabled per pin via the Quartus programming file. Architecturally, the EPM570T144C3N uses a flash-based non-volatile configuration cell so it behaves like an ASIC at power-up - no external boot memory is required and the device is functional within microseconds of VCC ramp. The 5.4 ns pin-to-pin delay and ~300 MHz maximum frequency make it well suited to high-speed decoding, interrupt steering, and register-intensive glue logic on boards containing microprocessors, microcontrollers, or DSPs. Typical applications include I/O expansion and voltage translation between microcontrollers and peripherals, glue logic in communications infrastructure (routers, switches, base stations), industrial control and factory-automation boards, automotive body and infotainment controllers, and consumer-electronics glue that previously required discrete 74-series logic. It is also a popular choice for prototyping because designs can be rapidly iterated in Altera/Intel Quartus and programmed in-system. When designing with this part, verify that the Quartus II / Quartus Prime version targeted by the firmware is compatible with the EPM570T144 device family, and budget decoupling capacitance as recommended in the MAX II handbook. The non-volatile flash cell array means retention and endurance limits should be reviewed for production programming volumes.
