The Altera (now Intel) EPM570GT100I5N is a 440-macrocell CPLD from the MAX II family, fabricated on a 0.18-µm 6-layer-metal flash process with non-volatile instant-on configuration. Housed in a 100-pin TQFP package, the device delivers 570 logic elements, 8 Kbits of user flash memory, and pin-to-pin propagation delays as low as 5.4 ns, making it suitable for glue-logic, bus-bridging, I/O expansion, and power-sequencing tasks in cost-sensitive industrial and consumer designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing and instant-on behavior of traditional PAL/GAL architectures with the density of an FPGA's logic fabric. Within the broader hierarchy of digital ICs, the CPLD sits between simple SPLDs (PALs/GALs) and high-density FPGAs, offering instant-on flash storage, predictable routing delays, and wide I/O support without requiring an external configuration memory. Key features of the EPM570GT100I5N include 76 user I/Os, MultiVolt core supporting 1.8 V, 2.5 V, and 3.3 V interfaces on the same device, an internal oscillator, JTAG boundary-scan, and on-chip user flash memory for storing revision data, serial numbers, or look-up tables. The GT100 package variant specifies a 100-pin Thin Quad Flat Pack with industrial temperature range (-40 °C to +100 °C). The I5 speed grade corresponds to the 5.4 ns tPD1 propagation delay. Architecturally, the MAX II CPLD uses a uniform logic-element array interconnected by a continuous MultiTrack interconnect, eliminating the row/column routing bottlenecks of legacy CPLDs. Each logic element contains a 4-input look-up table, a programmable register, and a carry chain, supporting efficient implementation of counters, state machines, and arithmetic logic. The embedded flash block provides 8 Kbits of general-purpose non-volatile storage. Typical applications include bus interface bridging (e.g., 8-bit MCU to 16-bit peripheral), power-supply sequencing in multi-rail systems, LED display drivers, configuration of FPGAs via SPI/I2C, and industrial control boards requiring instant-on deterministic startup. The wide I/O count and MultiVolt support also suit the part for legacy peripheral replacement. When designing with this device, observe the maximum I/O count and pin assignments for the 100-TQFP package; unused I/Os should be configured as outputs driving low or left as inputs with internal pull-ups enabled. The internal 8-Kbit UFM is independent of the logic fabric and can be accessed via JTAG or a user logic block.

EPM570GT144C3 - MAX II 570 LE CPLD, 5.4ns, 144-TQFP | Intel
The Intel EPM570GT144C3 is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs), delivering 570 Logic Elements (LEs), 8 Kbits of user flash memory (UFM), and a 5.4 ns pin-to-pin propagation delay in a 144-pin TQFP (GT144) package with commercial temperature grading. Manufactured on a 0.30 µm 6-layer-metal flash process, it targets glue-logic, bus-bridging, and control-plane applications where low cost, non-volatile configuration, and instant-on behavior are required. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device built from multiple PAL-like macrocells interconnected by a global routing interconnect. It occupies a position in the programmable logic hierarchy between discrete logic gates (smallest) and FPGAs (largest and highest-density), offering deterministic timing, instant-on operation from on-chip flash, and high-drive I/O suitable for bus-interface and control-plane tasks. MAX II devices specifically combine the lowest static power of any CPLD family with non-volatile storage and a built-in user flash memory block for system housekeeping data. Key features of the EPM570GT144C3 include 440 macrocells, 76 user-available I/Os in the 144-pin TQFP package, MultiVolt I/O support (1.5V, 1.8V, 2.5V, 3.3V mixed-voltage interfaces), 1.8V core supply with on-chip voltage regulator, JTAG-based IEEE 1149.1 in-system programmability (ISP), and a built-in UFM block (8 Kbits) that can store user data such as serial numbers, configuration parameters, or boot code. The device consumes as little as 35 µA of standby current in power-saving modes. Architecturally, the MAX II device combines a non-volatile flash configuration cell with a volatile SRAM-based logic fabric, where each Logic Element contains a 4-input look-up table (LUT), a programmable register, and a carry chain for arithmetic. The flash cell holds the configuration permanently, eliminating the need for an external boot PROM and enabling instant-on operation within microseconds of power-up. The MultiVolt I/O banks allow direct interfacing to 1.5V, 1.8V, 2.5V, and 3.3V logic without external level shifters. Typical applications include bus-interface bridging (PCI to local bus, I2C to SPI), power-sequencer and supervisory logic for FPGA-based systems, address decoding and glue logic in microcontroller designs, industrial control and factory automation, and consumer electronics requiring low-cost, low-power programmable logic. The 144-pin TQFP package is suitable for hand-solderable prototypes and low-volume through-hole-friendly manufacturing, as opposed to the FineLine BGA variants used in high-density portable designs. When designing with the EPM570GT144C3, plan for the Quartus Prime design suite (MAX II device support) and verify that I/O bank voltage assignments match the connected logic rails; misuse of MultiVolt banks is the most common cause of CPLD I/O failures during bring-up. The 5.4 ns tPD1 figure is sufficient for sub-200 MHz glue-logic applications but should be derated against temperature for worst-case timing closure.

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.

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.

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).

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.

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.

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. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design considerations not collated in the manufacturer datasheet alone, helping engineers select the right MAX II variant for cost, speed, and temperature requirements.

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.

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.

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.

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.

The Intel (formerly Altera) EPM570T100C4N is a MAX II family Complex Programmable Logic Device (CPLD) delivering 570 logic elements and 440 macrocells in a 100-pin TQFP (14x14 mm) package. 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.

EPM570T100C5 - MAX II CPLD, 440 Macrocells, 100TQFP | Intel
The Intel EPM570T100C5 is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs) featuring 570 logic elements and 440 macrocells in a 100-pin TQFP (14x14 mm) package. Built on a 0.18 µm process technology, the device operates with an internal supply voltage of 2.5 V/3.3 V and supports a maximum toggle frequency of 201.1 MHz with a pin-to-pin propagation delay of 5.4 ns. The MAX II architecture integrates a non-volatile Flash configuration memory, eliminating the need for external boot PROMs and simplifying in-system programming (ISP) via the standard IEEE 1149.1 JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of PAL/GAL architecture with high-density macrocell arrays, sitting hierarchically between simple PLDs and FPGAs in the programmable logic taxonomy: PLD -> CPLD -> FPGA -> programmable logic -> semiconductor. MAX II devices target glue-logic, bus-interface, I/O expansion, and power-sequencing roles where deterministic timing, low standby power, and instant-on configuration are required. Key features include 76 user I/O pins, multi-voltage I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V) through banked VCCIO pins, 8 Kbits of user Flash memory, and a built-in Joint Test Action Group (JTAG) boundary-scan test interface compliant with IEEE 1149.1. The device supports in-system programmability through the JTAG port, allowing field upgrades without removing the part from the board. Typical applications include bus-interface bridging (for example, address decoding between microcontrollers and external peripherals), I/O expansion, power-supply sequencing in multi-rail systems, and glue-logic replacement for legacy discrete 74-series TTL/CMOS logic. The MAX II instant-on, non-volatile configuration makes the EPM570T100C5 particularly suitable for safety-critical and industrial systems that cannot tolerate FPGA configuration delays at power-up. This page synthesizes distributor pricing, drop-in alternatives within the MAX II family, and practical design notes that complement the manufacturer datasheet, helping engineers evaluate the EPM570T100C5 against newer MAX V / MAX 10 options.
EPM570T100C5N - MAX II 570 LE CPLD, 100-TQFP | Intel (Altera)
The Intel (Altera) EPM570T100C5N is a non-volatile, instant-on Complex Programmable Logic Device (CPLD) from the MAX II family, featuring 570 logic elements (440 macrocells), 76 user I/Os, and a 201.1 MHz internal performance, packaged in a 100-pin TQFP (T100) form factor. It is fabricated on a 0.18-µm 6-layer-metal Flash process and supports 2.5 V and 3.3 V operation across the commercial 0 °C to +85 °C temperature range. A CPLD (Complex Programmable Logic Device) is a non-volatile digital IC that combines multiple PLA-like macrocell blocks on a single die with on-chip Flash configuration memory, providing instant-on logic at power-up without an external boot device. CPLDs sit in the programmable-logic hierarchy above discrete glue logic and below FPGAs, offering deterministic timing, low power, and pin-configurable I/O for bus decoding, state-machine, and interface-bridging tasks. Key features include 8 Kbits of user Flash memory, in-system programmability (ISP) through IEEE 1149.1 JTAG, MultiVolt I/O supporting 1.5 V / 1.8 V / 2.5 V / 3.3 V interface levels, and a low-power standby mode. The on-chip voltage regulator accepts a single 3.3 V supply and generates the internal core voltage, simplifying board design. The MAX II family is targeted at cost-sensitive glue-logic, bus-bridge, and power-sequencing functions where FPGAs are overkill. From an architecture perspective, the device uses a Logic Array Block (LAB) structure with 16 macrocells per LAB, an enhanced interconnect matrix, and a Joint Test Action Group (JTAG) interface compliant with IEEE Std 1149.1. The 8-Kbit user Flash can hold configuration revision data, serial numbers, or small lookup tables, eliminating the need for an external EEPROM in many designs. Typical applications include I/O expansion and bus decoding for microcontrollers, FPGA/CPLD configuration and power-up sequencing, LED driving and PWM generation, retro-computing glue logic, glue logic for ASIC/ASSP replacement, and JTAG-controlled board-test fixtures. Designers use the EPM570T100C5N where deterministic pin-to-pin timing, instant-on behavior, and small board area are critical. A key design consideration is the MultiVolt I/O bank configuration: each I/O bank can independently mix 1.5 V, 1.8 V, 2.5 V, and 3.3 V signaling levels provided the VCCIO rails are correctly grouped. Designers should consult the device pinout to plan bank assignments before PCB layout, since incorrect bank partitioning can lead to level-shifter rework.
