EPM5192LI-2 - 192-Macrocell MAX 5000 PLD | Altera | 84-Pin PLCC
The Altera EPM5192LI-2 is a high-speed, high-density CMOS Erasable Programmable Logic Device (EPLD) from the MAX 5000 family, delivering 192 macrocells, 64 I/O lines, and a tpd of 55 ns in an 84-pin PLCC (JEDEC S-PQCC-J84) package. It is the lower-power LI suffix variant and the speed grade -2 derivative of the EPM5192 base device, optimized for industrial temperature operation (-40 C to +85 C) on a 4.5 V to 5.5 V single supply. What is a MAX 5000 device? The Altera MAX (Multiple Array matriX) 5000 series is a classic UV-erasable/OTP Complex Programmable Logic Device (CPLD) family, sitting in the PLD hierarchy between simple PAL/GAL SPLDs and modern SRAM-based FPGAs. Architecturally, a MAX 5000 CPLD partitions logic into interconnected Logic Array Blocks (LABs), each containing a programmable AND/OR array feeding multiple macrocells with configurable flip-flops. Compared to a discrete PAL, a MAX 5000 CPLD provides higher density, predictable timing, and non-volatile (UV-erasable) configuration, while remaining far simpler than an FPGA - no external boot PROM, deterministic pin-to-pin delays, and a unified 5 V supply rail. Key features of the EPM5192LI-2 include 192 macrocells organized into 12 LABs, 72 total inputs (7 dedicated + 64 I/O), 64 user I/O lines, 55 ns pin-to-pin propagation delay, and 100 MHz internal counter frequency. Power consumption is typically 600 mW at 5 V/25 C, and the device supports in-system programming via Altera's MAX+plus II design toolchain. The 84-pin PLCC (J-lead) package offers a socket-compatible upgrade path for legacy designs. From an architectural standpoint, the EPM5192LI-2 uses Altera's classic EEPROM/UV configuration cell with a fast programmable interconnect (PIA) that routes signals between LABs. Each macrocell includes a product-term steering logic block, a programmable flip-flop (D/T/JK), and a user-configurable I/O architecture, giving the designer dense combinational plus registered logic without external glue. The -2 speed grade and the -LI (lower-power, industrial-temperature) suffix make this part well-suited for designs that previously used a 74-series TTL/SPLD combination but now require more logic per board. Typical applications include industrial control glue logic, address decoding in microprocessor/DSP systems, bus interfacing (e.g., ISA, PC/104, VME), state-machine controllers, peripheral replacement, and legacy telecom backplane logic. The 192-macrocell density suits designs that previously required multiple PALs or discrete SSI/MSI logic. When designing with the EPM5192LI-2, engineers should budget the device's worst-case Icc of approximately 600 mW and verify timing with MAX+plus II timing simulation, since the 55 ns tpd directly limits clock frequency at 18 MHz. The 84-pin PLCC package is windowed ceramic or OTP plastic; ensure your programmer supports the EPM5192 JEDEC file format. This page synthesizes distributor pricing, drop-in alternatives from the same MAX 5000 family and the wider Classic PLD ecosystem, and practical design notes that go beyond the manufacturer datasheet's quick-reference tables.
EPM5192LI84 - 192-Macrocell MAX 5000 CPLD 84-PLCC | Altera
The Altera EPM5192LI84 is a UV-Erasable/OTP Complex Programmable Logic Device (PLD) from the MAX 5000 family, providing 192 macro cells and 3,750 usable gates in an 84-pin Plastic Leaded Chip Carrier (PLCC) package. It operates from a single 5 V supply and supports a pin-to-pin propagation delay of approximately 25 ns, with a maximum toggle frequency of 40 MHz. The LI84 suffix indicates the industrial temperature grade (-40 °C to +85 °C) and the J-lead PLCC J84 package code (QCCJ). A Complex Programmable Logic Device (CPLD) is a non-volatile, flash- or EPROM-based logic device that implements glue logic, state machines, bus decoding, and interface bridging functions between fixed-function ICs. The MAX 5000 family sits within Altera's broader programmable logic hierarchy: CPLD -> Programmable Logic Device (PLD) -> Programmable Logic -> Digital Semiconductor. CPLDs are distinguished from FPGAs by their deterministic timing, instant-on non-volatile configuration, and pin-to-pin delay specifications that do not vary with logic utilization. Key features of the EPM5192LI84 include 192 macro cells, 3.75 K usable gates, 64 user I/O pins, a JTAG-based in-system programming interface (not all variants), and an OTP/UV-erasable configuration memory that retains pattern data without external storage. The PLCC-84 socket-compatible package is removable for laboratory UV erasure and re-programming, which historically made this family attractive for prototyping and low-volume industrial designs. The device uses Altera's classic MAX architecture with an EEPROM/EPROM-based AND plane feeding a fixed OR-plane macro cell fabric. Each macro cell contains a programmable flip-flop, product-term selection logic, and an I/O control block. Logic synthesis is performed with Altera's MAX+PLUS II or Quartus design tools, which are still maintained in legacy mode for industrial customers servicing long-lifecycle equipment. Typical applications include legacy industrial control replacement, military/aerospace avionics refresh (via the JM/883 MIL-STD-883B variants), telecommunications backplane glue logic, and bus-interface bridging in long-lifecycle OEM equipment. The OTP nature makes the EPM5192LI84 suited to designs where the pattern is finalized and re-programming is rarely required. When designing with this part, note that the LI84 device does NOT support in-system programmability - the JTAG port is absent on most MAX 5000 OTP variants, so a stand-alone programmer (e.g. Altera Logic Programmer or compatible third-party tools) is required. Use the LC84 (windowed ceramic) variant if UV erasure is anticipated, and reserve proper decoupling on every VCC/ground pin pair to meet the 5 V TTL I/O switching noise budget. This page synthesizes distributor pricing snapshots, same-brand pin-compatible variants already published on XAIPART (EPM5192LI family members), and practical design notes not found in the legacy Altera datasheet alone.

The device features a 40 ns propagation delay (tPD) in the -1 speed grade and supports a maximum clock frequency of 50 MHz, making it suitable for glue-logic, bus decoding, and state-machine integration in legacy 5V systems. A Programmable Logic Device (PLD) is a digital integrated circuit whose logic function is configured by the end user after manufacture. Within the broader taxonomy, MAX 5000 devices belong to the One-Time-Programmable (OTP) windowless PLD family, sitting between simple SPLDs and high-density CPLDs/FPGAs in density. They are organized as interconnected Logic Array Blocks (LABs) joined by a Programmable Interconnect Array (PIA), with the EPM5192QC-1 implementing 12 LABs and a shared external clock input feeding all macrocells. Key specifications include 192 macrocells, 64 user I/O lines, 7 dedicated inputs, a 5 V supply range of 4.75 V to 5.25 V, and a -1 speed grade delivering 40 ns pin-to-pin delay. The OTP EPROM-style configuration cell eliminates window erasure and supports surface-mount assembly without quartz erase windows, unlike earlier UV-erasable MAX parts. Architecturally, the EPM5192QC-1 uses a sum-of-products macrocell with a programmable AND/OR plane feeding a configurable output register. Each macrocell supports combinational or registered operation with feedback, and the PIA routes every LAB signal to every other LAB for full connectivity. The shared clock pin and dedicated clock-enable network simplify synchronous design across all 192 flip-flops. Typical applications include 5V microprocessor peripheral decoding, address/data bus arbitration, DMA/state-machine controllers, industrial control glue logic, and legacy telecom backplane glue. The PQFP-100 footprint is widely supported on through-hole adapters for retrofit designs. When designing with this device, ensure that switching noise on the 5 V rail does not exceed the 5.25 V abs-max rating, and use a high-frequency decoupling network (0.1 uF + 10 uF) within 5 mm of every VCC/ground pair to meet tPD specifications under full I/O switching load.

The instant-on, deterministic-timing characteristics make it especially valuable in power-rail sequencing for processor cores, memory subsystems, and complex SoCs that require controlled bring-up. When designing with the EPM570F100I5, pay careful attention to the FBGA-100 PCB footprint - a 1.0 mm ball pitch requires precise land pattern design and reflow profile control. Use the Altera/Intel Quartus II design software (legacy) or Quartus Prime to develop, simulate, and program the device; the JTAG interface supports in-system programming after PCB assembly. Provide proper decoupling on each VCCINT and VCCIO bank and follow Intel's recommended BGA routing escape pattern to minimize via stubs and signal-integrity issues on high-speed outputs.

Typical applications include power-on reset and sequencing control in industrial automation, I/O expansion and bus bridging in networking line cards, address decoding in microcontroller systems, and digital signal conditioning in test and measurement equipment. Designers also choose MAX II CPLDs as glue-logic consolidation parts to reduce discrete MSI/SSI logic on the board. When designing with the EPM570F256C4, treat the 256-ball FineLine BGA as a fine-pitch package that requires careful PCB layout: matched-length impedance traces, a 6- or 8-layer stack-up with continuous ground planes, and Xilinx/Altera-compatible BGA fanout. Quartus II software supports this device through the free Quartus Prime Lite / Web Edition toolchain.

EPM570F256C4N - 570 LEs, 440 Macro, 256-FBGA CPLD | Intel / Altera
The Intel (formerly Altera) EPM570F256C4N is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs) built on a 0.18 µm, 6-layer-metal flash process. It integrates 570 Logic Elements (equivalent to 440 macrocells) into a 256-ball FineLine BGA (FBGA) package, with 160 user I/O pins and an in-system programmable user flash memory (UFM) block of 8 Kbits. Operating from 2.5V/3.3V supplies, the device supports MultiVolt I/O interfacing across 1.5V, 1.8V, 2.5V, and 3.3V logic families. What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-on programmable logic IC that combines the deterministic timing and instant-on characteristics of PAL/PLA arrays with the higher logic density and I/O count of modern FPGAs. MAX II CPLDs sit in the hierarchy: programmable logic → CPLD → non-volatile CPLD → MAX II family, bridging glue-logic and simple state-machine tasks that do not justify the cost or boot-time of an SRAM-based FPGA. The 256-pin FineLine BGA package is the largest pin-count option for the MAX II family, enabling the highest I/O count and supporting vertical migration to EPM1270 and EPM2210 in the same footprint. Key features include a maximum operating frequency of 304 MHz (internal), 5.4 ns pin-to-pin logic delay, MultiVolt core and I/O support, JTAG-based in-system programmability (ISP), and an 8 Kbit user flash memory block for storing user-defined data such as serial numbers or configuration parameters. The 256-ball FineLine BGA provides a compact 17 mm × 17 mm footprint suitable for space-constrained designs. Architecturally, the EPM570F256C4N uses a Logic Array Block (LAB) structure of 57 LABs, each containing 10 Logic Elements. The non-volatile flash configuration cell eliminates external boot memory and provides instant-on behavior in < 1 ms, a defining advantage over SRAM FPGAs in power-sequenced and brown-out-sensitive systems. The MultiVolt I/O ring simplifies interfacing with mixed-voltage ASICs, ASSPs, and microcontrollers without level shifters. Typical applications include I/O expansion and bus bridging in industrial control, glue-logic consolidation in communications infrastructure, power-sequencing and reset-distribution logic, LED display scan drivers, and low-cost state-machine controllers. The combination of high I/O count (160) and instant-on non-volatile configuration makes the EPM570F256C4N ideal for designs where deterministic startup and high pin count are required simultaneously. Design consideration: vertical migration within the MAX II family is supported in the 256-pin FineLine BGA — EPM570, EPM1270, and EPM2210 share the same ball map, allowing a single PCB layout to serve multiple density points. Decoupling must follow the MAX II pin connection guidelines with multiple VCCINT and VCCIO pins requiring local 0.1 µF + bulk capacitors.

EPM570F256C5 - MAX II CPLD, 570 LE, 256-BGA, 201 MHz | Intel / Altera
The Intel / Altera EPM570F256C5 is a MAX II family Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements, 440 macro cells, and 160 user I/O pins in a 256-ball FineLine BGA package. It is built on a 0.18 µm flash-based process, supports 2.5 V and 3.3 V core supply operation, and delivers a maximum toggle frequency of 201.1 MHz with a pin-to-pin logic delay (tPD) of 5.4 ns. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic IC that combines the deterministic timing of PAL/GAL architectures with modern flash memory. In the system hierarchy, the CPLD sits below the FPGA (which offers higher density but requires a configuration boot), above simple glue-logic gates, and alongside microcontrollers as a complementary logic resource used for bus bridging, I/O expansion, power-up sequencing, and custom interface glue. Key features of the EPM570F256C5 include in-system programmability (ISP) via JTAG (IEEE 1149.1), 8 Kbits of user flash memory, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and a commercial operating temperature grade of 0 °C to +85 °C. The 256-ball FBGA package provides a compact footprint while exposing enough I/O for wide bus multiplexing. Architecturally, the device uses a uniform interconnect matrix of Logic Array Blocks (LABs) and a global fast-input network, which guarantees fixed-pin-to-pin timing regardless of how the logic is placed. This deterministic timing is the primary engineering reason to choose a CPLD over a small FPGA for control-plane logic. Typical applications include I/O expansion and bus bridging in industrial controllers, glue logic between ASSPs and processors, JTAG-controlled power-up sequencing for FPGAs and SoCs, and protocol translation (LVCMOS/LVTTL bridging). The wide MultiVolt I/O range makes it suitable for interfacing legacy 5 V-tolerant buses through external resistors. When designing with this part, observe that 'C5' denotes the 5 ns speed grade (commercial), the 'N' suffix would denote lead-free, and the 'F' in the prefix indicates the FBGA package family. JTAG chain length must be considered when multiple devices share one TAP controller. Pricing as of 2026-09-12 is around $10 per unit in low quantities from authorized distributors. This page synthesizes cross-reference data, drop-in same-family alternatives, and design guidance that complements the official Altera MAX II Device Handbook without replacing it.

The Altera EPM570F256C5N is a member of the MAX II family of instant-on, non-volatile CPLDs, based on a 0.18-um process technology and offering 570 Logic Elements and 440 Macrocells in a 256-ball FineLine BGA package. It operates from a 2.5V or 3.3V internal supply and supports 160 user I/Os with a 5.4 ns pin-to-pin logic delay. The non-volatile flash configuration memory provides instant-on behavior at power-up with no external boot PROM required, a key differentiator versus SRAM-based FPGAs/CPLDs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a programmable interconnect matrix. In the broader programmable-logic hierarchy, CPLDs sit below FPGAs in density but above simple SPLDs in capability, offering deterministic timing, low power, and instant-on characteristics. MAX II devices target glue-logic, I/O expansion, bus interfacing, and power-sequencing roles where SRAM FPGAs are overkill. Key features include 5.4 ns tPD, 304 MHz internal performance, 8 Kbits of user flash memory, in-system programmability via JTAG, and MultiVolt I/O supporting 1.5V, 1.8V, 2.5V, and 3.3V interfaces. The device consumes low standby current and supports commercial 0C to 85C operation. The MultiVolt core allows the device to interface seamlessly to modern processors, ASICs, and other programmable devices on mixed-voltage boards without external level translators. Architecturally, the EPM570F256C5N uses a flash-based Look-Up Table (LUT) fabric rather than the older MAX-style product-term array, which raises usable logic capacity while keeping propagation delay short. The non-volatile flash cell also eliminates the boot configuration stage, simplifying board layout and reducing bill-of-materials cost versus SRAM-based counterparts. Typical applications include I/O expansion and bridging in industrial controllers, address decoding and glue logic in embedded systems, bus multiplexing for legacy peripherals, power-up sequencing in multi-rail designs, and configuration control for processor subsystems. Its instant-on behavior makes it well suited to deterministic boot paths. When designing with the MAX II CPLD, ensure the Quartus II toolchain is used for synthesis and fitting. Verify pin assignments against the 256-FBGA pinout file and respect MultiVolt bank grouping when mixing 1.8V and 3.3V signals on the same die. This page combines distributor pricing, drop-in pin-compatible alternatives drawn from the same MAX II family, and practical PCB design notes that go beyond what is printed in the manufacturer datasheet.
EPM570F256C5NRR - MAX II CPLD, 570 LEs, 256-BGA | Intel
The Intel (formerly Altera) EPM570F256C5NRR is a non-volatile, low-power MAX II Complex Programmable Logic Device (CPLD) featuring 570 Logic Elements, 440 macro cells, and a 256-ball FineLine BGA (FBGA) package. The 'C5' speed grade delivers 8.7 ns pin-to-pin logic delay (fMAX around 201 MHz internal) while consuming only a few tens of milliamps on a 2.5V/3.3V dual-supply core/IO scheme. It provides instant-on non-volatile configuration via on-chip flash, eliminating external boot memory and shortening power-up latency to microseconds. A CPLD (Complex Programmable Logic Device) is a non-volatile digital IC that combines AND/OR array logic with macro cells, used to implement glue logic, state machines, bus interfaces, and protocol bridges. MAX II sits in the broader hierarchy of programmable logic: PAL/GAL -> SPLD -> CPLD -> FPGA, with CPLDs chosen over FPGAs when designers need fast deterministic pin-to-pin timing, low static power, instant-on configuration, and small-to-moderate logic densities in the 32- to 1,000-LE range. The EPM570 specifically targets designs that need more headroom than entry-level MAX II Z (EPM240) variants while staying below the cost of a low-end FPGA. Key differentiating features include 8.0 Kbytes of user flash memory (UFM) block, support for hot-socketing and JTAG (IEEE 1149.1) boundary-scan, 4 mA IOL drive, in-system programmability via JTAG, and a 0.18 µm flash-based process that allows 100% factory retention of the bitstream across power cycles. The dual-voltage core (2.5 V) and I/O (2.5 V/3.3 V) rails let the device bridge 3.3 V peripherals to 2.5 V controllers without external level shifters on every bus. Architecturally, MAX II uses a Logic Array Block (LAB) topology of 16 macro cells each, interconnected by a FastTrack Continuous Interconnect Matrix (CIM) that delivers predictable ~8 ns timing regardless of placement. The C5 speed grade is the commercial-temperature variant, suitable for 0 °C to +85 °C operation; an 'I' speed-grade variant exists for industrial -40 °C to +100 °C designs. Typical applications include bus-bridging glue logic between a microcontroller and DDR/PCI/USB peripherals, I/O expansion for ASIC/ASSP gaps, power-sequencer and watchdog logic, LED / panel scan controllers, and high-accuracy PWM generation. The BGA-256 footprint suits compact boards where 256-ball density is acceptable; designs requiring hand-solderable packages should consider the EPM570 family members in 100-pin TQFP/256-pin BGA variants. When laying out this device, route the 256 balls on a minimum 1.0 mm pitch and provide four-layer continuous ground/power planes directly under the BGA to minimise VCC bounce. Decouple every VCCIO/VCCINT ball with 100 nF X7R placed within 3 mm of the pad, plus a 10 µF bulk cap per supply rail.

EPM570F256I5 - 570-LE MAX II CPLD, 256-BGA, Industrial | Intel / Altera
The Intel (formerly Altera) EPM570F256I5 is a non-volatile, flash-based MAX II Complex Programmable Logic Device (CPLD) featuring 570 logic elements, 160 user I/O pins, and 8 Kbits of user flash memory, housed in a 256-ball FineLine BGA package. It operates across industrial temperature range (-40C to +85C) with a 3.3V core supply and supports both 3.3V and mixed-voltage 1.5V/1.8V/2.5V/3.3V I/O banks via MultiVolt core and I/O interfaces. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device built from a fabric of Look-Up Tables (LUTs), macrocells, and a programmable interconnect network. In the broader programmable logic taxonomy, CPLDs sit alongside FPGAs as the two dominant families of programmable logic; CPLDs are characterized by deterministic, pin-to-pin propagation delays (typically <10 ns), non-volatile on-chip flash storage, low standby current, and instant-on behavior, making them ideal for glue-logic, bus bridging, I/O expansion, and power-up control tasks where FPGAs are overkill. The MAX II family specifically uses a 0.18 um flash process with a look-up-table based logic array (LE) rather than the older product-term macrocell, giving it higher density per die area while preserving CPLD simplicity. Key features of the EPM570F256I5 include 570 logic elements, 160 maximum user I/Os, 8 Kbits of user flash memory (UFM) usable as general-purpose non-volatile storage, on-chip termination support, JTAG-based in-system programmability (ISP), and MultiVolt I/O that interoperates with 1.5V/1.8V/2.5V/3.3V/5V systems. The device supports I/O standards such as LVTTL, LVCMOS, SSTL, and PCI. Pin-to-pin logic delays in the I5 speed grade are typically in the 5-7 ns range with a maximum clock frequency around 304 MHz (per the MAX II datasheet). From an architecture standpoint, the MAX II family uses a logic-element based fabric divided into Logic Array Blocks (LABs) interconnected by a MultiTrack interconnect; each LE contains a 4-input LUT, a programmable register, and a carry chain, while the UFM block provides 8 Kbits of user-accessible flash that can store boot parameters, serial numbers, or lookup tables without an external EEPROM. The device also includes 4 phase-locked loops (PLLs) for clock synthesis and skew management. Typical applications include I/O expansion and bus bridging in industrial controllers, power-up sequencing and supervisory logic in multi-rail systems, glue-logic replacement for discrete 74-series logic, configuration control for FPGAs and microcontrollers, and protocol translation (UART-to-SPI, I2C-to-parallel) in embedded designs. Its instant-on non-volatile configuration makes it particularly attractive as a companion logic device to ASICs, ASSPs, and microprocessors. When designing with this device, place decoupling capacitors (0.1 uF plus 10 uF bulk) adjacent to each supply pin, follow Intel/Altera Quartus II pin-out guidelines for the F256 BGA (1.0 mm pitch), and connect JTAG TMS/TCK/TDO/TDI to a standard 10-pin header for ISP. Be aware that the MAX II family is now NRND on the Intel product roadmap; for new designs, MAX V or MAX 10 FPGAs are recommended.

The Intel (formerly Altera) EPM570F256I5N is a MAX II family Complex Programmable Logic Device (CPLD) with 570 Logic Elements, 440 macrocells, and 160 user I/Os housed in a 256-ball FineLine BGA package. It features 5.4 ns pin-to-pin logic delay (tPD1) and a 304 MHz internal clock frequency, supported by an internal 1.8 V core with multi-voltage 2.5 V/3.3 V I/O support including LVTTL, LVCMOS, and PCI compliance up to 66 MHz. The non-volatile Flash configuration cell removes the need for a separate boot PROM and supports in-system programmability via JTAG (IEEE 1149.1) and IEEE 1532 standards. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/PLA-like macrocell blocks with a central interconnect matrix. CPLDs sit between simple SPLDs/gates and high-density FPGAs in the programmable logic hierarchy (CPLD -> programmable logic -> logic IC -> integrated circuit), offering instant-on behavior, deterministic timing, and excellent pin-to-pin performance for glue-logic, interface bridging, and bus decoding tasks. The MAX II architecture is built on a low-power 1.8 V core process and is widely used as a board-level companion to microcontrollers, ASICs, and FPGAs.

The device offers multi-track routing between Logic Array Blocks (LABs) and supports 4 global clock networks plus 2 global clear/reset signals. Unlike SRAM-based FPGAs, MAX II instant-on operation requires no external configuration memory. In practical designs the EPM570F256I5N is typically deployed for high-speed address decoding, bus width conversion (e.g., 8-bit to 16-bit multiplexing), I/O expansion, timing-sensitive control logic, and as a power-sequencer companion to larger microprocessors. Its deterministic 5.4 ns tPD makes it ideal for pipelined memory and parallel-bus interfaces where software-driven GPIO bit-banging would be too slow. When designing, plan for 1.8 V core and 2.5 V/3.3 V I/O rails; both JTAG and ISP programming require a 3.3 V VCCIO during configuration. Quartus II (or the newer Quartus Prime) software is required for synthesis, fitting, and programming. Compared with discrete 74-series glue logic the EPM570F256I5N consolidates dozens of packages into a single 17 mm x 17 mm BGA.

It delivers 570 Logic Elements (LEs), a 5.0 ns pin-to-pin propagation delay, and instant-on non-volatile configuration stored in on-chip flash memory, eliminating the external configuration PROM that legacy CPLDs require. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between discrete glue logic and FPGAs in the logic hierarchy. Compared to discrete 74-series logic, a CPLD integrates dozens to hundreds of gates, flip-flops, and product terms on a single chip; compared to an FPGA, a CPLD typically offers lower logic density but provides instant-on behavior, deterministic timing, and superior robustness for control-plane tasks such as bus interfacing, power sequencing, and I/O expansion. Key features include 570 Logic Elements, 440 macrocells, up to 212 user I/O pins, an internal flash configuration block, JTAG and in-system programmability (ISP), and multi-volt I/O support (1.5V, 1.8V, 2.5V, 3.3V). The 256-ball FBGA package supports high I/O count in a compact footprint, while the 0.18-micron process keeps standby current low. The instant-on architecture boots in microseconds, which is critical for power-up sequencing and bootstrap logic. The MAX II architecture combines a Look-Up Table (LUT) and product-term fabric with an embedded Flash Configuration Block, giving the designer a non-volatile, JTAG-programmable device with high Pin-to-Pin (tPD) speed. The I5N speed/temperature grade (industrial, -40C to +100C junction, fast 5 ns) is the most widely specified variant for commercial and industrial products. Typical applications include I/O expansion and voltage translation between mismatched logic domains, power-up sequencing for multi-rail systems, bus bridges for legacy microcontrollers and peripheral glue, and LED-driving or display-control logic in industrial controls. When designing with this device, ensure PCB layout provides clean power and ground planes under the FBGA, observe JTAG chain order if multiple devices share the chain, and verify that the Quartus II/Altera design tool targets the EPM570 device family to obtain correct place-and-route results.

The device supports in-system programmability via IEEE 1532 / IEEE 1149.1 JTAG and is fully RoHS compliant in a lead-free FBGA-100 package measuring 11 mm x 11 mm with a 1.0 mm ball pitch. Architecturally, the EPM570 divides its 570 logic elements into four Logic Array Blocks (LABs), each with 16 macrocells, and connects them through a programmable interconnect array (PIA). Eight user I/O pins per LAB feed signals into the PIA, while the LAB outputs drive the global interconnect and I/O pins, providing predictable, deterministic timing that is characteristic of CPLDs. Typical applications include bus bridging and glue logic in industrial controllers, I/O expansion for microcontrollers and ASICs, power-sequencing and reset distribution, LED drive multiplexing, and portable consumer devices where instant-on, low power, and small footprint are essential. The combination of Flash memory, JTAG ISP, and a small BGA footprint also makes the part attractive for space-constrained designs. When designing with the EPM570GF100C5N, observe the multi-voltage I/O banking constraints of MAX II devices and consult the Quartus II support for the legacy MAX II tool flow. For new designs, consider MAX V (5M570ZE64C5N, 5M570ZT100C5N) as the recommended migration path with improved I/O support.

EPM570GF100I5N - 570 LEs CPLD 100-FBGA 1.8V Industrial | Intel
The Intel (formerly Altera) EPM570GF100I5N is a MAX II family CPLD delivering 570 logic elements and 440 macrocells in a 100-ball FineLine BGA package with 76 user I/Os. It features 5.4 ns pin-to-pin propagation delay and supports up to 201.1 MHz internal operation, while drawing core power from a single 1.71 V to 1.89 V supply (nominally 1.8 V). What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits between discrete glue logic and FPGAs in the programmable logic hierarchy: CPLD -> PLD -> programmable logic -> digital IC -> semiconductor. MAX II devices are flash-based, so configuration is retained without an external boot PROM, and instant-on behavior is achieved at power-up. Compared with first-generation MAX devices, MAX II CPLDs offer higher logic density, lower power, and a MultiVolt I/O bank that interfaces directly to 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic without level shifters. The EPM570GF100I5N integrates 8 Kbits of user flash memory (UFM) alongside the logic array, allowing the same device to store both glue logic and small non-volatile parameter sets such as board IDs, calibration coefficients, or boot configuration. Its 0.18 µm process node and LVCMOS/LVTTL/PCI-compatible I/O buffers support hot-socketing and drive strengths suitable for bus interfaces common in industrial control boards. Architecturally, the device uses a logic-element to macrocell fabric connected via a fast, deterministic interconnect, which is the reason CPLDs beat small FPGAs at predictable timing-critical tasks such as address decoding, bus arbitration, and reset sequencing. I/O banks provide JTAG (IEEE 1149.1) boundary-scan support and a JTAG-based programming interface, allowing in-system programming via the standard Altera/Intel quartus_pgm flow. Typical applications include industrial I/O expansion, motor-control glue logic, address decoding for microprocessors, bus interface bridging, and power-up sequencing for multi-rail systems. Because the package is a 11 mm x 11 mm 1.0 mm-pitch FBGA, the part is best suited for reflow-capable production rather than hand prototyping. When designing with this part, ensure the JTAG chain is properly terminated with the recommended 4.7 kΩ pull-ups on TCK, TMS, TDI, and TDO. Decouple VCCINT and VCCIO rails separately with 0.1 µF and 10 µF capacitors placed within 5 mm of each ball; shared decoupling causes ground bounce that the deterministic timing cannot mask.

The 'G' suffix indicates the green (Pb-free, RoHS-compliant) industrial-grade option, while the 'F' denotes the FineLine BGA package and '256' the ball count. The -5 speed grade provides the slowest fMAX of the family, trading speed for cost. The MAX II architecture combines a 2-row LUT fabric with a continuous, non-volatile Flash configuration array. This dual advantage: instant-on at power-up and Flash-based storage that fits into a single chip. Unlike SRAM FPGAs that require boot PROMs and external configuration time, the EPM570GF256-5N is operational within microseconds of power-up. Typical applications include I/O expansion, bus bridging, glue logic, power sequencing, LED control, industrial control, and portable/consumer electronics where non-volatile, instant-on behavior matters. The wide operating temperature range also suits factory automation and outdoor equipment. When designing with the EPM570GF256-5N, use Quartus II Web Edition (legacy) or the newer Intel Quartus Prime Lite for design entry, synthesis, and place-and-route. Verify the PCB footprint matches the 256-ball FineLine BGA land pattern and route inner balls as needed to escape the dense array.

The 'C3' suffix indicates a commercial temperature grade with the -3 speed grade offering 8.7 ns pin-to-pin logic delay. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between discrete logic gates (74-series) and FPGAs in the programmable logic hierarchy. Unlike SRAM-based FPGAs that require an external configuration flash and long boot times, MAX II CPLDs configure themselves in microseconds from internal flash, making them well suited to glue-logic, bus-bridging, I/O expansion, and power-sequencing tasks in systems that demand deterministic, instant-on behavior. The MAX II family uses a fine-grained Look-Up Table (LUT) architecture rather than the classic macrocell-and-PAL structure of legacy CPLDs, allowing it to absorb functions that traditionally required multiple 36- or 72-macrocell devices. Key features of the EPM570GF256C3 include 8.7 ns tPD1 propagation delay, 300 MHz internal performance, in-system programmability (ISP) via JTAG, support for IEEE 1149.1 boundary-scan testing, and a MultiVolt core that can interface directly to 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic without level shifters. The on-chip 8 Kbit UFM block can store user data such as serial numbers, calibration tables, or boot parameters, eliminating a small EEPROM in many designs. Typical applications include I/O expansion and voltage-level translation between processors and peripherals, power-up and power-down sequencing for multi-rail systems, bus-interface bridging (for example, SPI-to-I2C or parallel-to-LVDS glue logic), LED and display control, motor-control PWM and timing, and board-management controllers in servers, routers, and industrial automation. The wide operating-voltage range and industrial-grade temperature option also make MAX II parts common in factory automation and automotive body-electronics modules. When designing with the EPM570GF256C3, observe the I/O bank supply constraints: each of the eight I/O banks can be powered independently, but all I/Os in the same bank must share a single VCCIO. Use Quartus II or the free Quartus Prime Lite Edition for synthesis, fitting, and programming file generation. Decoupling: place 0.1 uF and 10 uF capacitors close to each VCCINT and VCCIO pin pair as recommended by the Altera hardware design guidelines.

EPM570GF256C3N - 570 LEs MAX II G CPLD | Intel / Altera
The Intel (formerly Altera) EPM570GF256C3N is a MAX II G family CPLD (Complex Programmable Logic Device) offering 570 logic elements in a 256-ball FineLine BGA (GF256) package with industrial operating temperature range (-40C to +125C). A CPLD is a non-volatile programmable logic device that provides instant-on configuration from on-chip flash memory, combining the deterministic timing of a PAL/GAL architecture with the integration density of an FPGA. CPLDs sit in the programmable logic hierarchy between discrete 74-series glue logic and full FPGAs, and are commonly used for I/O expansion, bus bridging, power-up sequencing, and control state machines where sub-10 ns propagation delays and zero boot latency are required. Key features include 570 logic elements, 76 user I/Os, 4-input LUT-based logic blocks, an 8 Kbit user flash memory block, JTAG IEEE 1149.1 boundary-scan support, and an internal oscillator. The device operates from a single 3.3 V core supply (VCCINT) with multi-voltage I/O banks supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels. The GF256 FineLine BGA package measures 17 mm x 17 mm with a 1.0 mm ball pitch, providing high board density for space-constrained designs. The MAX II G architecture combines a flash-based configuration memory with a Look-Up Table (LUT) logic fabric, eliminating the external configuration PROM required by older SRAM FPGAs. This instant-on capability, combined with multi-voltage I/O support and low power consumption, makes the EPM570GF256C3N well suited for glue logic replacement, bus interface translation, and LED drive multiplexing in industrial and communications equipment. Typical applications include I/O expansion and level shifting for microcontrollers and ASICs, bus interface bridging between legacy and modern peripherals, control logic for power supply sequencing, LED drive and multiplexing in signage, and general-purpose glue logic replacement on industrial control boards. When designing with this part, take advantage of Quartus II design software for synthesis, place-and-route, and timing analysis. The 256-ball BGA footprint requires careful PCB layout with microvia technology for reliable assembly, and the device supports in-system programmability via JTAG for production line updates.

EPM570GF256C4 - MAX II CPLD 570 LE 256-FBGA 5.4ns | Intel
The Intel (formerly Altera) EPM570GF256C4 is a member of the MAX II family of Complex Programmable Logic Devices (CPLDs), delivering 570 Logic Elements (LEs), 440 macrocells, and 5.4 ns pin-to-pin logic delay in a 256-ball FineLine BGA (FBGA-256) package. It is fabricated on a low-power 0.18-micron CMOS process and operates from a single 1.71 V to 1.89 V core supply with multiple I/O bank voltages supported through dedicated VCCIO pins. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic device that combines multiple PAL/GAL-like logic blocks with a programmable interconnect matrix. Within the broader taxonomy, a CPLD sits between discrete 74-series glue logic (e.g., 74HC, 74LVT) and FPGAs, providing deterministic timing, instant boot-up, and high drive strength for I/O expansion, bus bridging, power sequencing, and interface glue logic. MAX II CPLDs use a flash-based configuration cell, so the device retains its logic image without an external boot PROM and supports in-system programmability via JTAG. Key features include 5.4 ns tPD (fastest speed grade in the EPM570 family), 8 dedicated input pins, multi-voltage I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V LVCMOS/LVTTL), 76 to 212 user I/O depending on package, an internal oscillator, and an on-chip voltage regulator that derives the core 1.8 V from an external 2.5 V to 3.3 V VCCINT supply. The 256-ball FBGA provides 212 maximum user I/Os and a 1.0 mm ball pitch. Architecturally, EPM570GF256C4 partitions its logic into 16 Logic Array Blocks (LABs), each containing 16 Logic Elements with 4-input look-up tables, programmable registers, and a LAB-wide control signal network. The MultiTrack interconnect provides predictable, fixed-delay routing that simplifies static timing closure. JTAG (IEEE 1149.1) is supported for boundary-scan test and in-system programming, and Quartus II (legacy) or Quartus Prime software is used for design entry and device programming. Typical applications include I/O expansion and voltage translation between 3.3 V MCUs and 1.8 V peripherals, instant-on power sequencing for FPGAs and ASICs, bus interface bridging (e.g., parallel-to-SPI glue), board-level glue logic replacement, and LED/display control in industrial control panels. When designing with EPM570GF256C4, observe the I/O bank grouping rules in the datasheet: each of the eight I/O banks must be powered by a single VCCIO rail, and unused I/O banks should have their VCCIO tied to a valid voltage to avoid floating inputs. A 100 nF decoupling capacitor should be placed adjacent to every VCCINT/VCCIO pair, and JTAG TCK should be series-terminated when driving long board traces.
