It features non-volatile Flash configuration memory, instant-on functionality at power-up, and a 4 ns pin-to-pin logic delay (C4 speed grade), making it suitable for low-latency glue-logic and bus-interface bridging. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/GAL architecture with the integration density of an FPGA. It sits in the programmable logic taxonomy between simple SPLDs (PAL/GAL) and high-density FPGAs, offering instant-on Flash memory and a MultiVolt core/I-O architecture. CPLDs are typically used for I/O expansion, bus bridging, power-up sequencing, and address decoding where deterministic timing and instant-on behavior are required. The MAX II G family extends the original MAX II lineup with higher logic density (up to 2210 LEs) while retaining the same 1.8 V core architecture. Key features include 8 Kbits of user Flash memory (UFM) block for in-system data storage, MultiVolt I/O support for interfacing between 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic levels, in-system programmability via JTAG (IEEE Std. 1149.1), and a wide operating temperature range of -40 °C to +125 °C. The device operates from a single 1.8 V core supply with I/O banks independently powered. Architecturally, the EPM570G uses a Logic Array Block (LAB) structure with 570 LEs organized into an interconnect network driven by a non-volatile Flash configuration memory. This eliminates the external boot PROM required by SRAM-based FPGAs and yields true instant-on behavior. The C4 speed grade provides 4 ns tPD (propagation delay) and a 304 MHz internal fMAX, enabling high-speed interface bridging between processors and peripherals. Typical applications include I/O expansion and bus bridging in industrial controllers, glue logic in networking line cards, power-up sequence controllers, address decoding in MCU/SoC systems, and protocol bridging between legacy 5 V and modern 1.8 V logic domains. The instant-on Flash makes it suitable for boot-time FPGA configuration management. When designing with this device, ensure that all I/O bank supplies are present before driving signals; the MultiVolt architecture requires each bank VCCIO to match the driven logic level. Use the Quartus II (or Intel Quartus Prime) design software with the MAX II device family library for synthesis and fitting.

The device includes JTAG (IEEE 1149.1) and ISP (In-System Programming) support via the standard Altera/Intel Quartus II toolchain. Architecturally, the MAX II family uses a look-up table (LUT)-based logic element array combined with non-volatile flash configuration, eliminating the external boot PROM required by legacy SRAM FPGAs. The internal 1.8V LDO regulator allows single 3.3V or 2.5V board rails, simplifying power tree design in cost-sensitive industrial and consumer systems. Typical applications include I/O expansion and level translation between 3.3V MCUs and 1.8V peripherals, power-up sequencing for multi-rail systems, address decoding in legacy microcontroller designs, glue logic between processors and peripherals, and state-machine controllers in industrial automation. The 256-FBGA package supports designs with high I/O density on a compact board footprint. When designing, ensure thermal vias are placed under the BGA thermal pad to dissipate the ~0.5W typical power budget. Programming requires Quartus II software and a JTAG download cable such as the Altera USB-Blaster or compatible programmer. Pin migration within the 256-pin FineLine BGA package allows upgrade to EPM1270 or EPM2210 density points without board redesign.

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.

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.

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.

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.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple SPLDs and large FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA -> programmable logic -> digital semiconductor. CPLDs use non-volatile flash or EEPROM configuration cells, giving them instant-on behavior at power-up with no external boot PROM, low static power, deterministic timing, and predictable routing delays. The EPM570GT144C5 specifically belongs to Intel's MAX II G family, which adds high-speed LVDS I/O support on top of the standard MAX II architecture, positioning it for low-cost glue-logic, bus bridging, I/O expansion, and power-sequencing roles. Key features include 440 macrocells across two logic array blocks, 8.0 Kbits of internal user flash memory for storing user-defined data, MultiVolt I/O supporting 1.5V/1.8V/2.5V/3.3V interfacing from a single 3.3V VCCINT supply, a 1.71V-1.89V VCCIO core range with internal regulator, JTAG-based IEEE Std 1149.1 in-system programmability, and high-speed LVDS I/O at up to 300 Mbps. The 144 TQFP provides 80 general-purpose user I/O pins. The MAX II G architecture combines a uniform interconnect fabric with Look-Up Table (LUT) based logic elements and a Flash-based configuration block, eliminating the need for an external configuration device. MultiVolt core and I/O structures let each I/O bank operate independently, simplifying mixed-voltage designs. Primary applications include I/O expansion for microcontrollers and ASICs, bus interface bridging (e.g., SPI-to-parallel, I2C-to-GPIO), power-supply sequencing and supervisory logic, address decoding and glue logic in embedded systems, and high-speed LVDS signal conditioning in industrial control and communications hardware. When designing, ensure the VCCINT internal regulator is properly bypassed with 0.1uF and 10uF capacitors as shown in the datasheet typical application circuit, and respect MultiVolt I/O bank grouping constraints when assigning mixed-voltage signals.

EPM570GT144C5N - 440 MacroCell CPLD, 5.4ns, MAX II | Altera/Intel
The Altera (Intel) EPM570GT144C5N is a high-density, non-volatile CPLD from the MAX II family, delivering 440 Logic Elements (Macrocells) in a 144-pin TQFP package with up to 212 user I/O pins. Built on a 0.18 µm flash-based process, it provides 5.4 ns pin-to-pin logic delay and a maximum internal operating frequency of 201.1 MHz, supporting I/O standards from 1.5V to 3.3V including LVCMOS, LVTTL, and PCI. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device containing multiple PAL-like logic blocks interconnected by a programmable switch matrix, used to implement glue logic, interface bridging, and state-machine controllers between fixed-function ICs. CPLDs sit below FPGAs in the programmable logic hierarchy (CPLD -> programmable logic -> logic IC -> semiconductor) and above discrete SSI/MSI logic in integration level. Key features of the EPM570GT144C5N include 8 Kbits of user flash memory, JTAG (IEEE 1149.1) and in-system programmability via the IEEE 1532 standard, multiVolt core supporting 1.8V/2.5V/3.3V operation, and Instant-On non-volatile configuration in under 1 ms. The device operates from a single 1.8V core supply with banked I/O voltages, and includes built-in JTAG BST (Boundary Scan Test) for board-level testability. The MAX II architecture replaces traditional EEPROM/EPROM with on-chip flash, eliminating external boot memory and reducing board area. Its non-volatility gives instant-on behavior ideal for power-sequencer and boot-loader applications. The 5.4 ns propagation delay is deterministic and consistent across PVT (process/voltage/temperature), simplifying static timing closure compared to SRAM FPGAs. Typical applications include bus interface bridging (e.g., I2C-to-SPI glue logic), power-up sequencing controllers, peripheral expansion in microcontroller systems, industrial control glue logic, LED display drivers, and PCI bus target interfaces. The wide 1.5V-3.3V LVCMOS support also suits legacy 5V-tolerant designs when paired with external resistor dividers. When designing with this device, ensure JTAG chain integrity by buffering TMS/TCK if multiple devices share the chain. Decouple each VCCINT and VCCIO bank with 0.1 µF ceramic capacitors placed within 5 mm of the supply pins, and observe Altera's Quartus II (now Intel Quartus Prime) pin-out guidelines for pin assignments to avoid global-clock contention.

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.
