EPM570GT100C3 - MAX II CPLD, 570 LEs, 100-TQFP | Altera (Intel)
The Intel (formerly Altera) EPM570GT100C3 is a non-volatile, instant-on CPLD from the MAX II family, delivering 570 logic elements (440 macrocells) with a 304 MHz internal operating frequency, fabricated on a 0.18 µm 6-layer-metal flash process and housed in a 100-pin TQFP (14x14 mm) package. It integrates 8 Kbits of user flash memory (UFM), supports in-system programmability (ISP) via JTAG, and operates from a 1.71 V to 1.89 V core supply with MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V interfaces. According to the manufacturer datasheet, the EPM570GT100C3 belongs to the commercial extended temperature grade and consumes low standby current, making it suited for glue-logic and power-management sequencer applications. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on, deterministic behavior of traditional PAL/GAL architectures with modern flash-backed configuration memory. In the broader programmable logic hierarchy, CPLDs sit below FPGAs in density but above simple PLDs in capability, offering deterministic timing, high I/O count, and zero-configuration boot time. The MAX II family specifically targets low-power, low-cost glue logic, bus bridging, and I/O expansion roles that FPGAs over-serve. Key features of the EPM570GT100C3 include 570 logic elements (440 equivalent macrocells), 76 maximum user I/O pins, four global clocks, an 8 Kbit UFM block, JTAG/IEEE 1149.1 boundary-scan support, and MultiVolt core allowing mixed-voltage interfacing on a single die. Its flash-backed non-volatile configuration means zero configuration time on power-up, a critical advantage over SRAM-based FPGAs in deterministic boot applications. The device uses a Lab/Logic Array Block (LAB) architecture with each LAB containing 16 macrocells and a programmable interconnect array (PIA). The 0.18 µm embedded flash process delivers low dynamic power and high noise immunity, while the 100-pin TQFP package with exposed-pad-compatible footprint simplifies thermal dissipation in space-constrained designs. Typical applications include I/O expansion and bus bridging in industrial controllers, power-supply sequencing and supervisory glue logic, interface translation between 3.3 V and 1.8 V domains, LED display drivers, and legacy peripheral replacement. The commercial-extended temperature grade also suits benign industrial environments and telecom line cards. When designing with the EPM570GT100C3, observe the I/O bank VCCIO constraints (each bank must be powered before or simultaneously with the core VCCINT) and provide adequate decoupling (0.1 µF ceramic at every VCC pin) to suppress flash-programming noise. The Quartus II / Quartus Prime toolchain is required for synthesis, fitting, and JTAG programming.

EPM570GT100C3N - MAX II CPLD 440 Macrocells 76 I/O TQFP-100 | Intel
The Intel EPM570GT100C3N is a member of the MAX II CPLD family featuring 570 Logic Elements, 440 macrocells, and 76 user I/O pins, housed in a 100-pin TQFP package (14x14 mm). Built on a 0.18 um process, the device operates from a 1.71 V to 1.89 V core supply (1.8 V typical) and supports 3.3 V, 2.5 V, and 1.8 V I/O standards via multi-voltage pins. Maximum pin-to-pin propagation delay (tPD) is 5.4 ns and the device is in-system programmable via JTAG (IEEE 1149.1). MAX II CPLDs combine the non-volatile storage of Flash with the logic density of look-up tables, providing instant-on operation and eliminating the need for a separate boot PROM. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the hierarchy between simple SPLDs/PLDs and FPGAs. It uses a small AND/OR fabric (here, 440 macrocells arranged in Logic Array Blocks) to implement combinational and registered logic. Compared with FPGAs, CPLDs offer lower power, deterministic timing, and instant-on behavior. Within Intel's portfolio, the MAX II family occupies the glue-logic and control-plane role, sitting between the MAX 10 and the Cyclone series. The 'G' suffix indicates a 'Green' power variant of the original MAX II family. Key features of the EPM570GT100C3N include 8 Kbits of user Flash memory, MultiVolt I/O supporting 1.5/1.8/2.5/3.3 V interfaces, bus-hold circuitry on user I/O, JTAG-based in-system programmability, and support for the Quartus II design software. The 100-pin TQFP package supports commercial operating junction temperature (0C to 85C). The 76 available user I/O pins (after subtracting JTAG, power, and dedicated configuration pins from the 100-pin count) are sufficient to interface multiple microcontrollers, bus bridges, and glue-logic functions in a single device. The internal architecture combines a flash-based configuration store with a multi-level interconnect, four LABs feeding into macrocells with configurable flip-flops, and a JTAG-compliant boundary scan chain. This architecture yields deterministic 5.4 ns tPD regardless of logic utilization, a hallmark of CPLDs versus SRAM-based FPGAs. The MultiVolt core and I/O rails allow direct interfacing with 3.3 V MCUs and 1.8 V ASICs from a single chip. Typical applications include bus-interface bridging (PCI to local bus, I2C/SPI multiplexing), I/O expansion for microcontrollers, power-sequencer and reset-controller logic, motor-control state machines, LED-display drivers, and industrial control glue logic. The instant-on behavior is favored in industrial automation where the controller must be ready within milliseconds of power-up. A key design consideration is that 100-pin TQFP packages are hand-solderable and rework-friendly, unlike BGA variants in the same family. Designers migrating from the older MAX II to MAX II G should verify the VCCINT supply ramp and JTAG chain because, although pin-compatible, internal supply tolerances differ between the two revisions.

It operates from a 1.71 V to 1.89 V internal core supply with 2.5 V/3.3 V multi-voltage I/O support, and is in-system programmable via JTAG. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single chip, providing instant-on behavior, deterministic timing, and high-drive I/O. Within the broader semiconductor taxonomy, a CPLD sits below an FPGA in density but above discrete 74-series glue logic in integration. The MAX II family from Intel/Altera specifically targets replacing multiple 74LS/HC/CMOS logic chips with a single low-cost, low-power device, while offering non-volatile flash storage so the configuration is retained without an external boot PROM. Key features of the EPM570GT100C4 include 570 LEs distributed across 440 macro cells, 5.4 ns tPD (pin-to-pin delay), up to 304 MHz internal performance, in-system programmability (ISP) through IEEE 1149.1 JTAG, and a MultiVolt I/O interface that allows interfacing with 1.5 V, 1.8 V, 2.5 V, and 3.3 V devices without level shifters. The TQFP-100 package provides 100 user I/O pins and is rated for the commercial extended temperature range. The device uses a low-power, non-volatile flash-based architecture, giving it zero standby current configuration retention. The UFM (User Flash Memory) block provides up to 8 Kbits of user-accessible flash for storing constants, serial numbers, or boot code. Compared to SRAM-based FPGAs, MAX II CPLDs do not require a configuration bitstream at power-up, making them ideal for instant-on control applications. Typical applications include industrial control logic, I/O expansion and bridging, bus interfacing, power-sequencing controllers, and glue-logic consolidation. The wide I/O voltage range and instant-on behavior also make it suitable for automotive body electronics, telecommunications line cards, and consumer product controllers. When designing with this device, ensure that Quartus II or the latest Quartus Prime programmer is used for JTAG programming, and that the JTAG chain is properly terminated with the TCK/TMS TDI/TDO pull-ups as recommended in the MAX II Device Handbook. The 100-TQFP package's thermal pad should be soldered to the ground plane for improved power dissipation and signal integrity.

EPM570GT100C4N - 570 LEs MAX II CPLD | Intel TQFP-100
The Intel (formerly Altera) EPM570GT100C4N is a non-volatile MAX II family Complex Programmable Logic Device (CPLD) delivering 570 Logic Elements (equivalent to 440 macrocells), 8 Kbits of user flash memory (UFM), and up to 76 user I/O pins in a 100-pin TQFP package. Built on a low-power 0.18 µm 6-layer-metal flash process, it operates across a 1.8 V core (VCCINT) with MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfacing without external level shifters. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix, providing instant-on operation, deterministic timing, and in-system programmability (ISP). Within the programmable-logic taxonomy, CPLDs sit between small PALs/GALs and large FPGAs: more capable than discrete glue logic yet simpler, lower-cost, and lower-power than SRAM-based FPGAs. The MAX II family from Altera (now Intel FPGA) extends CPLDs into the logic-integration tier by adding an on-chip user flash memory block and supporting JTAG-based ISP for board-level configuration. Key features of the EPM570GT100C4N include MultiVolt core and JTAG 1149.1 boundary-scan support, 8 Kbits of UFM usable for non-volatile parameter storage, fast propagation delays in the sub-nanosecond range (tPD approximately 4.5 ns for the C4 speed grade), and zero-power standby when the device is idle. It supports instant-on operation because configuration is stored in on-chip flash rather than external SRAM, so the device is functional within microseconds of VCC ramp. Architecturally, the EPM570 uses the Logic Array Block (LAB) structure of the classic MAX family combined with the MultiTrack interconnect of the MAX 7000 series, exposed through the Quartus II / Quartus Prime design toolchain. The C4 speed grade is the second-fastest grade offered on the TQFP-100 footprint, balanced against the C5 (slower) and C3 (fastest) variants on the same package, enabling designers to trade timing margin for cost without re-laying out the PCB. Typical applications include bus-interface bridging, I/O expansion, power-up sequencing, custom decode logic, glue logic replacement for ASICs, and configuration storage with on-chip UFM. Industrial control, consumer electronics, and portable/handheld designs benefit from the low quiescent current and instant-on behavior. Design consideration: when migrating within the TQFP-100 footprint, the EPM570, EPM1270, and EPM2210 share vertical migration compatibility, allowing density upgrades without PCB redesign. The -4 speed grade targets cost-sensitive designs where the small extra timing margin versus -3 is acceptable.

The part 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 and 5 V interfaces, and offers a typical propagation delay (tPD) of 5.4 ns. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a sum-of-products macrocell fabric to implement glue logic, state machines, bus bridging and interface protocol conversion. In the broader system hierarchy, a CPLD sits alongside the FPGA as a programmable logic category under the broader Programmable Logic umbrella. MAX II devices are designed for low-power, low-cost, non-volatile logic integration, making them ideal companions to microcontrollers, ASSPs and processors that require fast, deterministic boot-time logic and pin-controlled configuration. Key features of the EPM570GT100C5 include 76 maximum user I/O, 8 Kbits of UFM for storing user data such as firmware parameters or serial numbers, JTAG IEEE 1149.1 boundary-scan and in-system programmability (ISP) via the built-in JTAG interface, MultiVolt I/O for level mixing without external translators, and a commercial operating temperature grade (0 °C to +85 °C). The non-volatile flash configuration enables instant-on behavior with no external boot PROM, unlike SRAM-based FPGAs. Architecturally, MAX II devices use a logic element (LE) fabric with a continuous routing network and per-I/O programmable pull-ups, slew rate and bus-hold. The 8 Kbit UFM block can be read or written from the logic fabric for parameter storage, and the MultiVolt core allows 1.8 V core operation with mixed-voltage I/O for direct bridging between 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5 V domains. Typical applications include power-sequence and reset management, I/O expansion and bus bridging between microcontrollers and peripherals, LED display driving, industrial control logic, glue logic in telecom line cards, and consumer electronics. The instant-on non-volatile fabric makes the device particularly suited to safety-critical or boot-deterministic designs. When designing, ensure that all I/O banks are powered correctly for the desired interface voltage and that the JTAG chain ordering matches the datasheet. Designers should also budget for the 1.8 V core supply separately from the I/O supply and check that total I/O utilization stays below the 76-pin maximum when accounting for JTAG pins.

It is built on a 0.18-µm, 6-layer-metal flash process and supports vertical migration within the same package with the EPM1270 and EPM2210 devices. The device features MultiVolt core support, an on-chip User Flash Memory (UFM) block of 8 Kbits, and JTAG-based in-system programmability (ISP). A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on semiconductor that integrates multiple PAL-like logic blocks into a single chip, sitting in the hierarchy between discrete 74-series glue logic and full FPGAs. CPLDs are widely used for bus bridging, I/O expansion, power-up control sequencing, and interface glue logic because they retain their configuration without an external boot ROM and provide deterministic, sub-9 ns pin-to-pin delays.

JTAG-compliant IEEE 1149.1 boundary-scan testing is supported, and ISP allows board-level reprogramming through the JTAG pins. The MAX II architecture is composed of Logic Array Blocks (LABs) of 16 LEs each, connected by a continuous Row and Column interconnect, with each LE containing a 4-input LUT, a programmable register, and a carry chain for fast arithmetic. The flash-based configuration memory provides instant-on behavior in less than 1 ms, eliminating the FPGA-style configuration wait and making the device suitable for power-supply sequencing and motor-control safety logic. Typical applications include bus-interface bridging between microcontrollers and peripherals, I/O expansion for industrial controllers, power-rail sequencing for multi-rail systems, and glue-logic replacement for legacy 74HC/74FTTL designs. The wide MultiVolt support also makes it well-suited for mixed-voltage boards where 3.3 V logic must talk to 1.8 V or 2.5 V devices. When designing, remember that vertical migration allows a single PCB to accept the EPM570, EPM1270, or EPM2210 in the same 100-pin TQFP, giving headroom for capacity expansion without re-layout. Decoupling the four core-supply pairs (VCCINT/VCCIO) with 0.1 µF ceramic capacitors placed within 3 mm of each pin is critical for jitter-free operation.

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.

Typical applications include I/O expansion and bus bridging in industrial controllers, power-sequencing logic in telecom line cards, address decoding in legacy microprocessor systems, and high-speed glue logic in consumer devices. Designers also use it as a low-cost re-programmable alternative to discrete 74-series logic for prototype-to-production transitions. A key design consideration is the device's 8 Kbit user Flash memory block which can be partitioned between logic configuration and user data storage, enabling on-board EEPROM-like functionality without an external memory chip. Vertical migration within the MAX II family is supported: EPM570, EPM1270, and EPM2210 share the same 256-pin FineLine BGA footprint, simplifying board scalability.

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. Decouple each VCC/VCCIO pin with a 0.1 µF X7R ceramic capacitor placed within 3 mm of the ball.

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.
