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.

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.

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.

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.

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.

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.

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.

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.

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.

EPM570T144C4 - 570 LEs, 116 I/O, 3.3V MAX II CPLD | Intel
The Intel (formerly Altera) EPM570T144C4 is a non-volatile, flash-based MAX II Complex Programmable Logic Device (CPLD) featuring 570 logic elements (440 macrocells) in a 144-pin TQFP package. It is built on a 6-layer-metal flash process and targets glue-logic, bus-bridging, and I/O expansion in cost-sensitive commercial and industrial systems. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip, providing fast, deterministic propagation delays ideal for implementing combinational and sequential glue logic, state machines, and bus interfaces. Within the broader taxonomy, CPLDs sit alongside FPGAs in the programmable logic hierarchy; however, CPLDs typically have lower logic density, lower power consumption, and instant-on non-volatile configuration - making them complementary to FPGAs rather than competitive. Key features of the EPM570T144C4 include 570 logic elements, 116 user I/Os (144-pin TQFP), 8 Kbits of user flash memory (UFM), MultiVolt core and I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V), and in-system programmability (ISP) via JTAG. Propagation delay is rated at 5.4 ns (pin-to-pin, tPD1) with a maximum internal frequency of 304 MHz, providing deterministic timing for asynchronous and high-speed interfaces. The MAX II architecture eliminates external configuration memory by storing the configuration in on-chip flash, enabling instant-on operation in under 1 ms - a critical feature for power-sequencing and boot-loader designs. The on-chip UFM block provides non-volatile parameter storage (firmware version, calibration data) without requiring a separate EEPROM. MultiVolt I/O supports interfacing directly to 3.3 V, 2.5 V, 1.8 V, and 1.5 V logic families on the same device, simplifying mixed-voltage designs. Typical applications include bus-bridging between legacy microcontrollers and modern peripherals, I/O expansion via serial-to-parallel or parallel-to-serial conversion, power-on sequencing in multi-rail systems, LED driving matrix controllers, and glue-logic replacement for discrete 74-series logic in commercial and industrial equipment. When designing with this device, observe the 1.8 V core supply requirement (VCCINT) and 3.3 V I/O supply (VCCIO) - the device does not support 5 V tolerant inputs without external level shifters.

The Intel (formerly Altera) EPM570T144C4N is a non-volatile, flash-based Complex Programmable Logic Device (CPLD) from the MAX II family, offering 570 logic elements (440 equivalent macrocells) in a 144-pin TQFP package. It operates from a 2.5V/3.3V core supply, supports MultiVolt I/O (1.5V, 1.8V, 2.5V, 3.3V) on its 212 user I/O pins, and provides a maximum user flash memory (UFM) of 8 Kbits alongside enhanced in-system programmability (ISP) through JTAG. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits in the hierarchy between simple logic gates and full FPGAs. Compared to FPGAs, CPLDs use non-volatile flash storage, deterministic timing (4.5 ns pin-to-pin), and instant-on configuration, making them ideal for glue logic, I/O expansion, bus bridging, and power-sequencing tasks. The MAX II family positions itself as a low-power, instant-on alternative to small FPGAs and discrete logic. Key features include a 247.5 MHz internal frequency, 5.4 ns tPD (pin-to-pin propagation delay), 0.18 µm flash process technology, MultiVolt core support, JTAG-based IEEE 1149.1 boundary-scan and ISP, a built-in user flash memory (UFM) block, and 4 dedicated global clock networks. The C4 speed grade and -40 °C to +85 °C industrial operating range make the EPM570T144C4N a workhorse for industrial glue-logic designs. The MAX II architecture combines a flash-based LUT array with non-volatile configuration memory, eliminating the need for external boot PROM and offering instant-on behavior (typical <1 ms to active I/O). The MultiVolt I/O ring allows direct interfacing with 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V systems without external level shifters, simplifying mixed-voltage board design. Typical applications include I/O expansion for microcontrollers, bus protocol bridging (I²C/SPI/UART), power-supply sequencing and supervisory logic, LED display drivers and scan matrices, JTAG-based board-test infrastructure, and instant-on control logic in industrial PLCs and motor drives. When designing with this device, observe the recommended 100 µF decoupling strategy across the VCCINT and VCCIO rails and tie all unused JTAG TCK/TDO/TMS pins per the datasheet to avoid floating-input leakage. Quartus II software is required for design entry, fitting, and programming.
