EPM570T100C5RR - MAX II CPLD, 570 LEs, 100-TQFP | Intel
The Intel (formerly Altera) EPM570T100C5RR is a MAX II family Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements (LEs), 440 macro cells, and 201.1 MHz maximum operating frequency, fabricated on a 0.18 µm CMOS process and supplied in a 100-pin TQFP package. The part operates from a 2.5 V / 3.3 V core supply and targets low-power, instant-on glue-logic applications. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash-based programmable logic device positioned between discrete glue logic (74-series gates) and small FPGAs. Compared with discrete logic, a CPLD provides deterministic timing, parallel processing of multiple I/O events, and a single-chip implementation that reduces board area and BOM cost. In the broader hierarchy, CPLDs sit within programmable logic devices (PLDs) alongside FPGAs, with MAX II occupying the low-power, low-density, instant-on tier. Key features of the EPM570T100C5RR include 8.7 ns pin-to-pin logic delay, 100 user I/O pins, an internal flash configuration memory that eliminates external boot PROM, in-system programmability via JTAG, and a 1.8 V core on 2.5 V / 3.3 V I/O. The architecture delivers an instant-on capability typical of MAX II devices, allowing logic to be active within microseconds of power-up — a notable advantage over SRAM-based FPGAs that require configuration loading. Technically, the EPM570T100C5RR organizes its 570 LEs into four Logic Array Blocks (LABs) interconnected by a MultiTrack interconnect fabric. Each LE contains a four-input LUT, a programmable register, and a carry chain, supporting combinational and registered logic with deterministic propagation delays ideal for bus decoding, state-machine control, and interface bridging. The 201.1 MHz fMAX applies to internal counter performance, with system-level design throughput typically constrained by I/O timing and signal integrity. Typical applications include I/O expansion and bus bridging for microcontrollers, power-sequencer logic in power-supply designs, glue logic replacing discrete 74-series gates in industrial controllers, LED and display driving, motor-control state machines, and instant-on control logic in consumer and industrial equipment where SRAM-FPGA boot time is unacceptable. When designing with this part, observe the 2.5 V / 3.3 V supply rail requirement and provide proper decoupling close to each supply pin. Quartus II software (free MAX II device support) is required for design entry, synthesis, and programming — JTAG pin assignment must follow the 100-TQFP pinout to ensure In-System Programmability (ISP) operation.

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

Key features include 570 logic elements, 440 macrocells, up to 76 user I/Os, an 8-Kbit internal user flash block, JTAG (IEEE 1149.1) and in-system programmability, and MultiVolt I/O that supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels from a single supply domain. Industrial temperature grade (-40C to +100C junction) and surface-mount TQFP-100 packaging suit it for harsh-environment designs. The device uses a non-volatile flash-based configuration cell array that eliminates the external boot PROM required by older SRAM-based CPLDs, reducing board area and BOM cost. The LAB (Logic Array Block) architecture connects 10 LEs per block through a fast interconnect, providing deterministic tPD propagation delays suitable for asynchronous and decoded-glue logic. Typical applications include I/O expansion and bus bridging in industrial control boards, HVAC and appliance controllers, LED display multiplexing, and power-sequencing logic in telecom/networking line cards. Designers choose the EPM570T100I5N when they need deterministic timing, instant-on behavior, and moderate logic density without FPGA cost. When designing with the EPM570T100I5N, place 0.1 uF decoupling capacitors adjacent to every VCCINT and VCCIO pin and respect the 100-pin TQFP thermal pad layout for multi-layer boards. Quartus II / Quartus Prime design software is required for synthesis, fitting, and JTAG programming.

The "-5" speed grade offers a tPD1 of approximately 5.0 ns, supporting designs clocked above 100 MHz internally and 200 MHz via dedicated clock networks, while commercial and industrial temperature grades provide operating range flexibility. Architecturally the EPM570 uses a non-volatile Flash configuration cell to retain the bitstream without external boot memory. The logic-array-blocks (LABs) are interconnected through a continuous MultiTrack interconnect, and routing is software-managed by the Quartus II / Quartus Prime toolchain. This architecture delivers instant-on operation: the device is functional within microseconds of power-up, eliminating the configuration-wait window typical of SRAM-based FPGAs. Typical applications include 3.3 V / 2.5 V / 1.8 V bus interface bridging, glue logic for microprocessors (8051, ARM Cortex-M, PowerPC), I/O expansion for FPGAs and ASICs, address decoding and chip-select generation, LED driving, configuration watchdog and reset sequencing, and industrial control / portable / power-management designs where instant-on behaviour is essential. When designing with the EPM570T144-5, ensure each VCCIO bank is decoupled with 0.1 µF and 10 µF capacitors placed close to the supply pins. The MultiVolt core allows the VCCINT supply to be powered at 3.3 V or 2.5 V while individual I/O banks interface to lower-voltage rails. JTAG programming pins (TCK, TMS, TDI, TDO) must be accessible for in-system updates; pull-ups on TCK, TMS and TDI are recommended per Altera's guidelines.

According to the Intel MAX II Device Handbook, the device operates from 1.8 V (core) with multi-voltage I/O banks supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V, and LVTTL/LVCMOS interfaces. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between discrete glue-logic ICs (74-series gates) and large SRAM FPGAs in the logic-hierarchy. CPLDs use flash or EEPROM configuration cells and a classic AND-OR PLA-style macrocell fabric, delivering deterministic timing, instant-on behavior (typically <1 ms wake-up), and high drive strength. CPLDs are widely used as interface bridges, bus controllers, address decoding, and power-up sequencers, where their deterministic timing and zero-config-latency offer advantages over SRAM FPGAs that require external boot memory and a multi-millisecond configuration phase. Key features of the EPM570T144I5 include 440 logic elements (macrocells), 8 Kbits of user flash memory (UFM), 116 user I/O, JTAG IEEE 1149.1 boundary-scan support, and multi-voltage I/O support across 1.5 V to 3.3 V standards. The 'I' suffix denotes the industrial temperature range (-40 °C to +100 °C junction), and the '5' speed grade corresponds to the 5.4 ns tPD1 timing specification. MultiCore architecture and Quartus II / Intel Quartus Prime design support enable straightforward design entry, synthesis, and in-system programming via JTAG. Typical applications include I/O expansion and bus bridging in industrial control, glue-logic consolidation in telecom line cards, address decoding and interrupt steering in embedded SBCs, and power-sequencing networks in ATCA/uTCA platforms. The non-volatile, instant-on nature also makes the EPM570T144I5 well suited to safety-critical applications where deterministic post-reset behavior is mandatory, and to low-volume ASIC replacement scenarios where NRE costs of an ASIC are not justified. When designing with the EPM570T144I5, observe I/O bank grouping rules - all I/O in a bank must share a single VCCIO supply - and budget at least four dedicated GND pins plus one decoupling capacitor pair (0.1 µF + bulk) per bank. The TQFP-144 exposed-pad footprint requires a continuous ground plane beneath the package to meet the 4-layer PCB thermal envelope.

The TQFP-144 package exposes all four sides for dense PCB trace routing, while the I5N speed grade targets industrial temperature applications. The MAX II architecture uses 4-input look-up tables feeding macrocell flip-flops with product-term distributed control, allowing flexible sum-of-products logic synthesis. Per the MAX II Family datasheet, the EPM570's flash-based configuration eliminates the need for external boot memory and provides bitstream-level security bits, making it suitable for tamper-resistant glue logic. Typical applications include I/O expansion for microcontrollers, bus decoding and address mapping, interface bridging between 3.3 V and 1.8 V logic domains, LED display row/column drivers, and power-supply sequencing controllers. The non-volatile instant-on behavior makes the part especially valuable in systems that must respond within milliseconds of power application. A key design consideration is I/O bank supply planning - VCCIO pins on each I/O bank must be tied to the correct voltage rail for the connected logic family. For high-toggle-rate outputs, derate maximum dc current per pin and total package dissipation per the MAX II handbook thermal tables.

It is built on a 0.18-µm 6-layer-metal flash process, supports in-system programmability via JTAG, and operates from a single 1.71 V to 1.89 V internal core supply with MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V interfaces. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that retains its configuration without external memory, offers deterministic pin-to-pin propagation delays, and is typically used for glue logic, bus bridging, and I/O expansion. Within the broader hierarchy, a CPLD sits under programmable logic -> logic IC -> semiconductor. MAX II CPLDs specifically target low-power, low-cost replacement of discrete logic and small FPGAs, integrating an 8-Kbit User Flash Memory (UFM) block alongside the logic array. Key features include 76 user I/Os, propagation delay of 9 ns pin-to-pin, 4-input look-up tables (LUTs), MultiVolt core, on-chip UFM with internal oscillator, JTAG-based IEEE 1532 in-system programmability, and commercial-to-industrial operating temperature support. The 100-ball FineLine BGA at 6x6 mm with 0.5 mm pitch provides high I/O density in a small footprint suitable for handheld and space-constrained designs. The MAX II architecture uses a non-volatile flash-based fabric, eliminating the external boot PROM required by SRAM FPGAs. This delivers instant-on behavior at < 1 ms and removes boot-related inrush current. The 8-Kbit UFM can store project parameters, serial numbers, or firmware versions - reducing BOM cost versus an external EEPROM. Typical applications include I/O expansion for microcontrollers, bus interface bridging (e.g., 8-bit to 16-bit or 3.3 V to 1.8 V), LED driving and display control, glue logic replacement for ASIC/SoC designs, and configuration storage. The wide MultiVolt I/O range allows direct connection to legacy 5 V tolerant, 3.3 V, and modern 1.8 V SoCs without level shifters. When designing with this device, ensure that all VCCIO banks are properly powered and decoupled; an unpowered bank will float inputs and risk back-powering through I/O pins. The JTAG chain must include proper TCK pull-down and TMS pull-up resistors per IEEE 1149.1. Quartus II software is required for design entry - older MAX+PLUS II designs will need migration.

The Altera EPM570ZM100C7N is a member of the MAX II family of instant-on, non-volatile Complex Programmable Logic Devices (CPLDs) that delivers 440 logic elements (equivalent to 440 macrocells) in a compact 100-ball Micro FineLine BGA (MBGA) package measuring 6 mm x 6 mm with 0.5 mm pitch. Built on a 0.18 um, 6-layer-metal flash process, the device operates from a 1.8 V core supply and targets glue-logic, bus-bridging, and state-machine replacement tasks that previously required multiple discrete PALs, GALs, or 74-series devices. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the deterministic timing of PAL/GAL architectures with the high integration of an FPGA. In the power-management hierarchy, CPLDs sit alongside microcontrollers, FPGAs, and DSPs under the broader Programmable Logic umbrella. Compared to small FPGAs, MAX II CPLDs offer instant-on behavior because the configuration is stored in on-chip flash, eliminating the external boot PROM typically required by SRAM-based FPGAs. This makes them well suited to system control, power-sequencing, and I/O expansion duties in cost-sensitive industrial and consumer designs. Key features include 440 logic elements, 76 user I/Os, 8 Kbits of on-chip user flash memory (UFM), 1.8 V core / MultiVolt I/O support, and a worst-case pin-to-pin propagation delay of 9 ns (speed grade 7). The non-volatile flash configuration means the device powers up already programmed, with no boot time, and supports in-system programmability (ISP) via JTAG. The 100-MBGA package supports vertical migration with the larger EPM1270 and EPM2210 in the same footprint. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up sequencing for multi-rail systems, glue-logic replacement in telecommunications line cards, LED display drivers, and portable/handheld products. The combination of non-volatility, low cost, and instant-on behavior makes the MAX II family a popular choice for designers consolidating discrete 74-series logic. When designing with the EPM570ZM100C7N, allow a generous keep-out around the BGA and use microvia or via-in-pad technology to fan out the 0.5 mm pitch balls. Provide at least four ground and two VCCINT (1.8 V) balls distributed around the package to ensure stable core power. The I/O banks support MultiVolt operation so 3.3 V, 2.5 V, and 1.8 V peripherals can be interfaced directly without level shifters.
EPM570ZM100I8N - 440-Macrocell MAX II CPLD, 100-BGA | Intel / Altera
The Intel / Altera EPM570ZM100I8N is a 440-macrocell MAX II zero-power CPLD delivering up to 152 MHz internal operation and 76 user I/O, packaged in a 100-ball FineLine BGA (MBGA).

What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, low-density programmable logic device that sits architecturally between discrete logic gates (74HC, 74LV) and FPGAs. CPLDs typically contain a few hundred to a few thousand macrocells organized into Logic Array Blocks (LABs) with a deterministic, non-volatile interconnect fabric. Compared to FPGAs, CPLDs have lower logic density, lower power consumption, instant-on configuration (< 1 ms), and a more predictable timing model that simplifies timing closure for glue-logic and bus-interface designs. Key features of the EPM570ZM100I8N include 570 Logic Elements, 57 LABs, 440 macrocells, 76 user I/Os, JTAG-compliant IEEE 1149.1 boundary-scan support, in-system programmability (ISP) via JTAG, a chip-wide DEV_OE output-enable pin, and on-chip flash user flash memory for user data storage. The MAX II family is built on a 0.18 μm flash process and is specified for the industrial -40 °C to +85 °C temperature range. Typical applications include bus-interface bridging (for example, address-latch or chip-select decoding in legacy microprocessor systems), power-sequencer logic, I/O expansion for microcontrollers, LED-display drivers, and configurable glue logic in industrial-control boards where the non-volatile, instant-on behavior of a CPLD is more attractive than an FPGA's configuration delay. When designing with this device, ensure PCB layout accommodates the 0.8 mm pitch FineLine BGA and that JTAG pins (TCK, TMS, TDI, TDO) are brought out to a test header. The EPM570Z's 1.8 V core must be supplied independently from the 3.3 V or 2.5 V I/O bank supply used by surrounding logic. Always reference the Altera MAX II Device Handbook for timing-model parameters.
EPM570ZM144C6N - MAX II CPLD, 570 LEs, 144-MBGA | Intel (Altera)
The Intel (formerly Altera) EPM570ZM144C6N is a non-volatile MAX II family CPLD (Complex Programmable Logic Device) with 570 logic elements (equivalent to 440 macrocells), packaged in a 144-ball Micro FBGA (ZM144, 6x6 mm, 0.5 mm pitch). It is built on a 0.18 µm 6-layer-metal flash process that retains configuration without an external boot PROM and offers up to 76 user I/O pins in this 144-MBGA variant. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines the instant-on, deterministic timing of classic PAL/PLA architectures with modern flash-based configuration memory. Within the broader semiconductor taxonomy, a CPLD sits alongside FPGAs in the programmable logic category, but differs by offering coarse-grained logic blocks, predictable pin-to-pin propagation, and zero configuration load time. MAX II devices occupy the low-power, low-cost end of this hierarchy, often serving as glue logic, bus bridges, and power-up state machines rather than high-density data processing. The EPM570 sits at the upper-middle density tier within the MAX II family, above EPM240 and EPM1270's smaller siblings. Key features include a 1.8 V core voltage with MultiVolt I/O support from 1.5 V to 3.3 V, an 8 Kbit user flash memory (UFM) block for non-logic data storage, in-system programmability via JTAG, and a maximum internal operating frequency quoted at 184.1 MHz with typical propagation delays in the low nanosecond range. The device supports vertical migration within the same package across the MAX II family (EPM240/EPM570/EPM1270 share footprints in several FineLine BGA variants), allowing density upgrades without PCB redesign. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up sequencing logic in multi-rail systems, LCD and display interface glue logic, address decoding for microcontrollers lacking address latches, and as a low-cost alternative to small FPGAs in volume consumer products. The on-chip UFM block enables designers to store serial numbers, calibration constants, or boot parameters without an external EEPROM. When designing with this part, ensure the JTAG chain is correctly terminated and that the MultiVolt I/O bank supplies match the connected logic levels. Decoupling follows standard CPLD practice: 0.1 µF ceramic per supply pin plus a single 10 µF bulk capacitor near the package. The non-volatile flash configuration means the device becomes active within microseconds of POR, simplifying system boot sequencing compared to SRAM-based FPGAs.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and FPGAs in the programmable logic hierarchy: CPLD -> programmable logic -> digital logic IC -> semiconductor. MAX II CPLDs deliver instant-on operation because their configuration is stored in on-chip flash rather than SRAM, eliminating external configuration memory and the associated boot delay. They are typically used for glue logic, bus bridging, I/O expansion, and power-up sequencing in systems that require deterministic, low-power, non-volatile logic without the cost or power of an FPGA. Key features of the EPM570ZM144C7N include 570 logic elements, 440 macrocells equivalent, 116 user I/Os (maximum), 8 Kbits of user flash memory (UFM), an internal oscillator, and JTAG (IEEE 1149.1) programming interface. The device operates from a single 3.3 V, 2.5 V, or 1.8 V core supply (multi-voltage support) and supports I/O bank voltages independent of the core supply, enabling mixed-voltage interfacing. The 144-MBGA package provides 116 usable I/Os with low parasitic inductance, well suited to high-speed signal fan-out and bus interface applications. The architecture consists of Logic Array Blocks (LABs) of 16 macrocells each, interconnected via a MultiTrack interconnect, with each macrocell containing a programmable register with a product-term-based combinatorial logic engine. The on-chip User Flash Memory (UFM) block of 8 Kbits allows user data storage such as serial numbers, calibration constants, or bootloader tables without an external EEPROM. An internal oscillator supports common baud-rate generation and timer functions. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up and power-down sequencing in multi-rail systems, glue logic for microcontrollers and ASICs, LED driving and display multiplexing, and protocol bridging (UART, I2C, SPI) for legacy or distributed architectures. The instant-on non-volatile configuration is particularly valuable in safety-critical and industrial applications where deterministic startup is required. When designing with the EPM570Z (MAX II Z) variant, note that the Z-license enables JTAG-based ISP but the UFM block is not present in all MAX II sub-families - verify the specific feature set against the device handbook. Power consumption is dominated by static Icc; a fully-loaded design with many toggling outputs should be validated against the Icc vs. frequency curves in the datasheet.

The device operates from a 1.8 V core supply and supports toggle frequencies up to 152 MHz with a pin-to-pin logic delay of approximately 9.0 ns, manufactured on a 0.18 µm process node. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash-based programmable logic IC that combines the instant-on behavior of a PAL/GAL with the density of a small FPGA. It sits between discrete 74-series glue logic and full FPGAs in the system hierarchy: glue logic -> SPLD -> CPLD -> FPGA -> ASIC. MAX II Z devices use a look-up table (LUT) based logic array plus a non-volatile flash configuration cell, giving them instant-on capability without external boot PROMs and excellent deterministic timing for bus-interface, address-decoding, and I/O-expansion tasks. Key features of the EPM570ZM144I8N include 570 logic elements organized as 57 Logic Array Blocks (LABs) of 10 macrocells each, 8 Kbits of user flash memory (UFM), JTAG (IEEE 1149.1) and Altera built-in ISP via the JTAG interface, MultiVolt core and I/O support allowing mixing of 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and four enhanced I/O banks. The I8N industrial temperature grade covers -40 °C to +85 °C operation, and the zero-power (Z) flash cell removes the need for a configuration download at every power-up. Architecturally, the EPM570Z is built around a fine-grained Logic Element (LE) array with carry chains for fast arithmetic, an interconnect network with predictable delay paths, and a global control block driving four clock inputs with programmable polarity. The flash-based configuration is in-system programmable (ISP) and re-programmable up to 100 cycles per sector, which is sufficient for board-level prototyping and small production runs. Typical applications include bus-interface bridging (PCI, ISA, VME legacy glue), address decoding and I/O expansion in microcontroller-based systems, power-up sequencing and supervisor logic, LED drive multiplexing, JTAG chain aggregation, and low-density state-machine replacement. Designers also use the EPM570Z as a feature-enhancement companion to an ASIC or MCU that lacks specific peripherals. When designing with the EPM570ZM144I8N, observe Micro FBGA routing rules — pitch is 1.0 mm and the device requires a 4-layer PCB with via-in-pad or micro-via escape patterns to fan out the 144 ball grid. Reserve at least 1 Gnd and 1 Vcc reference ball per quadrant and use the dedicated JTAG TCK/TMS/TDI/TDO pins for boundary-scan test. Quiescent current is approximately 35 mA at 1.8 V; total power scales with toggle rate and I/O loading.

The device also integrates 8 Kbits of user flash that designers can partition between configuration and general-purpose non-volatile storage. Architecture combines a high-performance, low-power CMOS process with the non-volatile Flash memory block, eliminating external configuration PROM and offering live-at-power-up behavior. The 160 user I/Os in a 256-MBGA footprint enable dense board integration where TQFP-144 or QFP-100 packages cannot deliver sufficient I/O count. Designers benefit from deterministic timing suited to control-plane and bus-interface applications rather than DSP or high-speed datapath workloads. Typical applications include I/O expansion and bus bridging for microcontrollers, glue logic replacement in industrial control boards, LED display control, multi-rail power-sequencing networks, telecommunications line-card interface glue, and consumer-electronics peripheral hubs. The wide I/O voltage range allows direct interfacing to legacy 5 V peripherals alongside modern 1.8 V SoCs. When designing with the EPM570ZM256C6N, remember that the MBGA package requires X-ray or rework-station inspection for prototypes and BGA-qualified PCB assembly lines for production. Provide decoupling of 0.1 microfarad and 10 microfarad capacitors near each VCCIO bank, and ensure JTAG chain access for in-system programming. Use Quartus II Web Edition (or Quartus Prime Lite) for design entry, synthesis, and place-and-route.

The Altera (now Intel) EPM570ZM256C7N is a MAX II Z family zero-power CPLD that delivers 570 Logic Elements (LEs) and 76 user I/Os in a 256-ball Micro BGA package, fabricated on a 0.18 µm CMOS process. It supports a core supply of 1.71 V to 1.89 V with on-chip voltage regulation, and operates at commercial temperature grade 0 °C to +85 °C. The device provides 440 macro cells and an internal maximum operating frequency of 123.5 MHz, making it well-suited for glue-logic, I/O expansion, and bus-bridging roles in cost-sensitive systems. A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic IC that combines multiple PAL-like macro cell blocks connected by a programmable interconnect matrix. Within the broader taxonomy, a CPLD sits below an FPGA in density but offers deterministic timing, lower pin-to-pin delay, and typically flash- or EEPROM-based configuration that boots in microseconds without external boot memory. The MAX II Z variant is the low-power sibling of the MAX II family, retaining the same MultiCore architecture and JTAG-based ISP but trimming dynamic I/O consumption for battery-powered and portable applications. Key features include 8 Kbits of user flash memory, 5.0 ns pin-to-pin logic delay, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, JTAG 1149.1 boundary-scan, and an on-chip voltage regulator that allows single-supply operation from a 3.3 V rail. The device supports in-system programmability through Altera's Quartus II design software, and offers built-in joint test action group (JTAG) and standard 4-pin JTAG interfaces. Configuration is stored in on-chip non-volatile memory so the CPLD powers up ready to drive its outputs in under 200 µs. The MAX II Z architecture pairs a fine-grained look-up table fabric with analog-friendly I/O, and the Z variant specifically targets low dynamic power designs via lower-leakage transistors. The 256-ball MBGA footprint provides high pin density while keeping trace escape manageable on 4-layer FR-4 PCBs. Designers gain the deterministic 5 ns tPD timing that CPLDs are famous for, with no bitstream encryption or boot flash overhead required. Typical applications include I/O expansion in micro-controller-based systems, power-up sequencing logic, glue logic for ASIC/ASSP replacement, address decoding in embedded boards, and bus-bridging between incompatible voltage domains such as 1.8 V FPGA banks and 3.3 V peripheral buses. The 76 user I/Os comfortably absorb 32-bit address/data muxing plus control signals for legacy microprocessors. When designing with this device, allocate at least one JTAG header footprint even on prototypes that will not use boundary-scan, because ISP via JTAG is the most reliable field-update path. Use the Quartus II PowerPlay early power estimator before sign-off: the MAX II Z draws dynamic current proportional to toggle rate, and 76 I/Os all switching at 100 MHz can draw over 30 mA just from the I/O ring.

EPM570ZM256I8N - MAX II 440 Macrocell CPLD, 256-MBGA | Intel
The Intel (formerly Altera) EPM570ZM256I8N is a non-volatile, instant-on MAX II family Complex Programmable Logic Device (CPLD) with 440 macrocells (570 logic elements), 118.3 MHz maximum internal frequency, and 1.71 V to 1.89 V core supply, housed in a 256-ball Micro FBGA (11 mm x 11 mm) package. The device integrates 8 Kbits of user flash memory for non-volatile configuration, eliminating the need for an external boot PROM and enabling instant-on behavior within microseconds of power-up. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL/GAL-style macrocell arrays with a central interconnect matrix. CPLDs sit between small discrete logic gates (74-series) and larger FPGAs in the programmable logic hierarchy. Within that hierarchy, the MAX II family is positioned as the lowest-power, lowest-cost instant-on tier from Intel/Altera, optimized for glue logic, I/O expansion, bus bridging, and power-sequencing tasks rather than DSP-intensive workloads. The 'Z' suffix denotes the zero-power (ultra-low static current) variant, which uses a 1.8 V internal core supply and is intended for battery- and thermally-constrained designs. Key features include in-system programmability via IEEE 1149.1 JTAG, MultiVolt I/O supporting 1.5 V / 1.8 V / 2.5 V / 3.3 V interfaces on the same die, four global clock networks with eight clocks per logic array block, and a 1.6 Kbit user flash memory block. The 256-MBGA package exposes 212 user I/O pins, supporting high-density I/O expansion in a compact 11 mm x 11 mm footprint. Internally, the EPM570Z uses a 0.18 micrometer, 6-layer-metal flash process and a non-volatile configuration cell, which keeps the device permanently configured without external boot storage. Each Logic Array Block (LAB) contains 16 macrocells, and the central interconnect matrix routes signals across LABs with predictable, deterministic timing that simplifies static-timing closure compared with SRAM-based FPGAs. Typical applications include I/O expansion for microcontrollers, voltage-level translation between mismatched logic domains, power-supply sequencing and supervisory logic, glue logic replacement for discrete 74-series gates, bus-interface bridging (for example, SPI-to-Parallel or I2C-to-GPIO expansion), and LED driving or keypad scanning in industrial and consumer products. Designers also use the EPM570Z as a companion CPLD to an FPGA, offloading boot configuration, clock conditioning, and reset distribution. When designing with this device, budget for the 1.71 V to 1.89 V core supply rail (typically derived from a 3.3 V LDO) and respect the JTAG chain requirements if multiple devices share the same TMS/TCK lines. The MultiVolt I/O banks allow direct connection to 3.3 V, 2.5 V, 1.8 V, or 1.5 V domains without external level shifters, but unused I/O pins should be configured as outputs driving low or tri-stated with weak pull-up to minimize in-rush current.

EPM7032LC44-15 - MAX 7000 CPLD, 32 Macrocells, 15ns | Altera
The Altera EPM7032LC44-15 is a high-performance, EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000 family, delivering 600 usable gates and 32 macrocells in a 44-pin PLCC package with 15 ns pin-to-pin logic delay. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip with a global interconnect fabric. CPLDs belong to the broader family of programmable logic devices, sitting alongside FPGAs in the digital IC hierarchy: programmable logic -> programmable logic device -> CPLD/FPGA -> logic IC -> integrated circuit. MAX 7000 devices use a second-generation MAX architecture with 5.0-V in-system programmability (ISP) through a built-in IEEE Std. 1149.1 JTAG interface, enabling designers to program, verify, and re-program the device on the board without removing it. Key features of the EPM7032LC44-15 include 32 macrocells, 36 user I/O pins, 600 gates of logic capacity, 15 ns tPD (pin-to-pin delay), and a maximum internal operating frequency of 76.9 MHz. The device operates from a single 5.0 V supply (with VCCIO supporting 5.0 V or 3.3 V outputs) and is housed in a 44-pin PLCC package suitable for through-hole mounting and socket-based prototyping. The MAX architecture uses a classic EEPROM-based non-volatile technology, providing instant-on behavior at power-up with no external configuration memory required. The 15 ns speed grade makes the LC44-15 suitable for control logic, address decoding, bus interfacing, and glue-logic integration where deterministic propagation delay and high I/O count are required. The PLCC-44 footprint is widely supported by low-cost sockets, simplifying field upgrades and legacy-system retrofits. Typical applications include address decoding and bus interfacing in industrial control systems, glue-logic replacement in legacy 5V designs, I/O expansion for microcontrollers, and state-machine implementation in test & measurement equipment. Designers select the -15 speed grade when balancing timing margin against cost in non-critical control paths. When designing with this device, ensure the VCC and VCCIO rails match the system logic levels. PLCC-44 sockets should be used for prototyping to allow easy device swap during development. Note that MAX 7000 devices have been classified by Altera/Intel as mature legacy products, so designers should verify long-term availability before new designs.
