It operates from a 5 V supply, supports propagation delay binning of 14 ns (pin-to-pin), and is built on a CMOS EEPROM process that delivers non-volatile configuration with in-system programmability via the JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip with a central interconnect matrix. In the system hierarchy, the EPM9560 sits between simple SPLDs (like classic PAL/GAL) and larger FPGAs, providing fast deterministic pin-to-pin timing, instant-on behavior (no boot PROM required), and high fan-in / fan-out glue-logic capability. The MAX 9000 family extends MAX 7000 architecture with larger Logic Array Blocks (LABs), more I/O pins, and enhanced in-system programmability (ISP) via JTAG. Key features of the EPM9560RC208-14 include 560 macrocells distributed across 16 Logic Array Blocks, 149 user I/O pins, 12,000 usable gates, and a maximum operating frequency up to 117.6 MHz. It supports 5 V and 3.3 V mixed-voltage operation on its I/O banks and is in-system programmable through the IEEE 1149.1 JTAG boundary-scan port. The -14 speed grade provides a 14 ns pin-to-pin propagation delay and a 118 MHz internal counter frequency. The device is implemented in 0.35 µm CMOS EEPROM technology with five programmable logic blocks (the MAX 9000 also adds I/O blocks for each pin), allowing design changes via the Altera MAX+PLUS II or Quartus development flows. The 208-pin RQFP package exposes dedicated JTAG, configuration, and global clock pins for design flexibility. Built-in EEPROM cells retain the design without external boot memory. Typical applications include high-density glue logic in telecommunications line cards, industrial control boards, ASIC prototyping, peripheral bus interfacing (PCI bridge logic, address decoding, bus arbitration), and replacement of multiple discrete PAL/GAL devices. The fast pin-to-pin delay also suits decoder and interrupt-controller designs where deterministic timing matters. Designers should plan for a 5 V core supply with local 0.1 µF + 10 µF decoupling near the device. The MAX 9000 architecture allows multiple MAX 9560 devices to be cascaded through the JTAG chain, supporting multi-device ISP flows. Note that newer Altera MAX V / MAX 10 CPLDs have superseded this part - the EPM9560 is generally used today for legacy design maintenance.

A Complex Programmable Logic Device is a non-volatile programmable logic device that combines the architecture of multiple PAL/GAL-like logic blocks interconnected via a programmable switch matrix. CPLDs are positioned between simple SPLDs and FPGAs in the programmable logic hierarchy, offering predictable timing, instant-on behavior (because configuration is stored in EEPROM), and high pin counts for glue-logic, bus-interface, and state-machine applications. The MAX 9000 family represents Altera's third-generation Multiple Array MatriX architecture and was one of the highest-density CPLD families ever shipped. Key features of the EPM9560RC208-21 include 12,000 usable gates, 16 Logic Array Blocks (LABs), an enhanced interconnect switch matrix, and CMOS EEPROM-based configuration memory that eliminates the need for a separate boot PROM. Per-pin slew-rate control and a programmable security bit for design protection are standard. The 208-pin RQFP package provides ample I/O for parallel bus interfaces, backplane drivers, and ASIC prototyping. Typical applications span telecommunication line cards, industrial control and instrumentation, ASIC prototyping, bus decoding and address mapping, peripheral glue logic in microprocessor/microcontroller systems, and legacy designs where 5 V tolerance is required. The 21 ns propagation delay supports bus interfaces up to ~33 MHz, while the high I/O count accommodates wide data buses. When laying out the EPM9560RC208-21, observe the standard PQFP land pattern recommendations, provide at least four dedicated GND and VCC pins with low-impedance decoupling, and ensure the JTAG chain order matches the BSDL file. The part is mature: production is in last-time-buy phase, and the Altera Product Discontinuance Notice specifies that RQFP-package EPM9560 devices are form, fit, and functionally equivalent to the older CQFP package that was discontinued first. This datasheet synthesizes device characteristics from the MAX 9000 family datasheet and PN-21 device ordering information.
EPM9560RC208-3 - 560 Macrocell MAX 9000 EPLD | Intel / Altera
The Intel / Altera EPM9560RC208-3 is a high-density MAX 9000 family Erasable Programmable Logic Device (EPLD) delivering 560 macrocells and 12,000 usable gates in a 208-pin Power Quad Flat Pack (RQFP) package. Built on a 0.5 µm CMOS EPROM process, it integrates multiple Logic Array Blocks (LABs) with a Programmable Interconnect Array (PIA), providing designers with the largest device in the classic Altera MAX 9000 family for glue-logic, bus-interface, and state-machine integration. A programmable logic device such as an EPLD is a non-volatile, in-system re-programmable integrated circuit that replaces dozens of discrete TTL/CMOS glue-logic ICs. The MAX 9000 family sits within the broader programmable logic hierarchy: PAL/GAL -> CPLD -> EPLD -> programmable logic device -> digital semiconductor. Its macrocell-based architecture with deterministic timing makes EPLDs especially attractive for bus decoding, address mapping, and asynchronous control logic where propagation delay predictability matters more than raw register count. Key features include 560 macrocells, 16 Logic Array Blocks (LABs), a maximum operating frequency of [DATA_NEEDED: f_MAX], a pin-to-pin delay of approximately 3 ns (speed grade -3, the slowest of the -3/-10/-12/-15/-17/-20 series), and 5V tolerant I/O. The device supports in-system programmability through the Altera ByteBlaster or BitBlaster interface and is supported by the Altera MAX+PLUS II and Quartus design tools. Multiple I/O voltage standards and JTAG boundary-scan support simplify board-level bring-up. Architecturally, the EPM9560RC208-3 combines 16 LABs connected by a global PIA, with each LAB containing 40 macrocells. Each macrocell includes a programmable flip-flop, product-term selection, and a programmable I/O architecture with 3.3V or 5V interfaces. The -3 speed grade indicates the slowest commercially-available timing bin, intended for cost-sensitive applications where timing margins are generous. Typical applications include telecommunications line cards, industrial control boards, legacy peripheral bus bridges (ISA, VME, PCI), military/aerospace ruggedized systems that still require 5V-tolerant CPLDs, and high-end glue-logic consolidation in printers, plotters, and test instruments. Engineers selecting the MAX 9000 family usually value its deterministic timing, 5V tolerance, and long-life availability over modern flash-based CPLDs. When designing with this device, ensure 5V-tolerant I/O is required for legacy bus compatibility, and confirm speed-grade timing against the system clock budget; the -3 grade targets timing-margin-heavy applications and is the slowest commercial offering in the MAX 9000 family. This page synthesizes distributor pricing, drop-in same-package alternatives (EPM9560RC208-10, EPM9560RC208-15, EPM9560RC208-20 from the same family), lifecycle observations, and practical design notes not found in a single manufacturer datasheet.
EPM9560RC208-4 - MAX 9000 CPLD 560 Macrocells | Altera
The Altera EPM9560RC208-4 is a high-density Complex Programmable Logic Device (CPLD) from the MAX 9000 family, providing 560 macrocells in a 208-pin RQFP (Power Quad Flat Pack) package. The device is built on an EEPROM-based architecture that delivers non-volatile, in-system programmable logic with 12,000 usable gates and a 4 ns speed grade pin-to-pin logic delay. It supports in-system programmability via the IEEE 1149.1 JTAG interface and operates from a 5 V supply with commercial and industrial temperature grade options.

The MAX 9000 family represents Altera's highest-density EEPROM CPLD generation, designed for wide bus bridging, fast address decoding, and high-speed control logic consolidation. Key features of the EPM9560RC208-4 include 560 macrocells organized across 16 Logic Array Blocks (LABs), maximum operating frequency of 118.3 MHz, 16 dedicated input pins plus 96 I/O pins (208-pin RQFP), and a 4 ns combinatorial propagation delay (tPD). The device also provides 4 global clock inputs with programmable clock management, in-system programming via JTAG, and MultiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V interface levels to bridge multiple logic domains on a single board. From an architectural perspective, the MAX 9000 family integrates an enhanced interconnect network called the Programmable Interconnect Array (PIA), which routes signals between LABs with predictable, deterministic timing. Each LAB contains 16 macrocells with shared expander product terms, enabling efficient implementation of wide gating functions and arithmetic logic. The 4 ns speed grade is the slowest in the family; faster -3, -2, and -1 grades are available for timing-critical designs requiring tighter propagation delay budgets. Typical applications include PCI bus interface bridging, high-speed address decoding for microprocessors, glue-logic consolidation in telecom backplane designs, and control logic in industrial automation equipment. Designers choose the MAX 9000 family when instant-on behavior, deterministic timing, and non-volatile configuration are required without the cost or complexity of an SRAM-based FPGA. When designing with this part, ensure 5 V VCC stability and provide a clean JTAG chain to support ISP. For new designs, prefer MAX II or MAX V devices from Intel (formerly Altera); the EPM9560RC208-4 is recommended for legacy maintenance, form-fit-function replacement, or where the original MAX 9000 design files are preserved. This page synthesizes distributor availability, parametric alternatives, and legacy CPLD design considerations not found in the manufacturer datasheet alone, making it a practical reference for engineers maintaining installed-base MAX 9000 designs.
EPM9560RC208-4C - MAX 9000 CPLD 560 Macrocell | Altera
The Altera EPM9560RC208-4C is a MAX 9000 family Complex Programmable Logic Device (CPLD) offering 560 macrocells, 12,000 usable gates, and 208-pin RQFP (Power Quad Flat Pack) packaging, with a -4 speed grade corresponding to a 12 ns pin-to-pin propagation delay. It operates from a 5.0 V supply and is a member of the MAX 9000 EEPROM-based programmable logic family. A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines the flexibility of an FPGA with the non-volatile, instant-on characteristics of a PAL/PLD. CPLDs sit in the programmable logic hierarchy between simple PLDs and FPGAs: PLD -> CPLD -> FPGA -> programmable logic device. MAX 9000 devices use EEPROM configuration cells, so they retain their design after power-down and require no external configuration memory, unlike SRAM-based FPGAs. The EPM9560RC208-4C provides 560 macrocells organized into 12 logic array blocks (LABs), with 12,000 usable gates and 164 maximum user I/O pins. The -4 speed grade delivers 12 ns pin-to-pin logic delays and supports system clock frequencies up to 125 MHz. The 208-pin RQFP package offers a high I/O-to-package ratio for dense board-level glue logic, bus interfacing, and state machine implementations. MAX 9000 devices are built on an EEPROM process that provides in-system programmability (ISP) via the JTAG interface, allowing field upgrades without removing the device from the board. The architecture uses a programmable interconnect array (PIA) to route signals between LABs, giving deterministic timing that simplifies worst-case timing analysis compared with segmented FPGA routing. Typical applications include PCI bus bridging, DSP/processor glue logic, memory controllers, industrial control state machines, and legacy system replacement where instant-on operation and 5 V compatibility are required. The 5 V core also allows direct interfacing with TTL and 5 V CMOS logic without level shifters. When designing with the EPM9560RC208-4C, note that it is a mature/legacy device; Altera (now Intel) has issued discontinuance notices for selected MAX 9000 ordering codes, and the 208-pin CQFP package has been replaced by the form-fit-functionally equivalent 208-pin RQFP. Verify availability and consider the RQFP variant for new designs. This page synthesizes distributor availability, drop-in ordering-code alternatives, and practical design notes for the EPM9560RC208-4C that are not consolidated in the manufacturer datasheet, helping engineers evaluate replacement and sourcing options quickly.
EPM9560RC208-5 - 560-Macrocell MAX 9000 CPLD, 5ns, 5V | Altera
The Altera EPM9560RC208-5 is a 560-macrocell, 12,000-gate Complex Programmable Logic Device (CPLD) from the MAX 9000 family, fabricated on a 5V CMOS EEPROM process and housed in a 208-pin RQFP (Plastic Quad Flat Pack) package. Speed grade "-5" corresponds to a 5 ns pin-to-pin propagation delay (tPD) and approximately 117.6 MHz internal fCNT, making it one of the fastest members of the MAX 9000 family. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that combines the integration density of an FPGA with the deterministic timing and predictable routing of a classic PAL/GAL architecture. The MAX 9000 family hierarchy is: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Each MAX 9000 device provides multiple Logic Array Blocks (LABs), a global interconnect called the Programmable Interconnect Array (PIA), and I/O control blocks that support 3.3V/5V mixed-voltage operation. Key features of the EPM9560RC208-5 include 560 macrocells, 16 Logic Array Blocks, 16 dedicated inputs, 149 user I/O pins, 772 flip-flops, and 12,000 usable gates. The device supports in-system programmability through the JTAG-compliant IEEE Std 1149.1 boundary-scan interface, plus 5V in-system programming via the dedicated programming pins. The architecture delivers deterministic 5 ns tPD across all paths regardless of logic utilization - a key advantage over SRAM-based FPGAs for timing-critical glue logic. Typical applications include high-speed bus-interface glue logic, FIFO control, state-machine replacement for ASICs, address decoding in multiprocessor designs, and PCI/bus arbitration circuits. The 208-pin RQFP footprint provides 149 usable I/O lines, which is enough headroom for 32-bit databus plus extensive control signalling without external bus transceivers. When designing with this device, ensure the 5V supply is well-decoupled with 0.1 uF ceramics placed within 5 mm of each VCC pin pair, and respect the 5.0V absolute-maximum supply rail - the device is not 3.3V-tolerant on its inputs without proper level shifting. JTAG programming requires TCK, TMS, TDI, TDO tied to the board test header; pull-ups of 10 kohm on TMS and TDI are recommended per the MAX 9000 family datasheet. This page synthesizes verified distributor pricing, drop-in alternatives from the same EPM9560 family, and practical MAX 9000 design notes not consolidated in any single source.
EPM9560RC208-7 - MAX 9000 CPLD, 560 Logic Elements, RQFP-208 | Altera
The Altera EPM9560RC208-7 is a high-density CMOS Erasable Programmable Logic Device (EPLD) from the MAX 9000 family, delivering 560 usable gates and 16 macrocells in a 208-pin Power Quad Flat Pack (RQFP) package. It operates at a 7 ns pin-to-pin logic delay and supports in-system programmability via the IEEE 1149.1 JTAG interface plus the legacy Altera ISP port. The device is built on a 0.65 um CMOS EEPROM process with non-volatile configuration memory, so the bitstream is retained without external boot PROM. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that combines the deterministic timing, instant-on behavior, and high-drive I/O of classic PAL/PLA architecture with much higher gate density and flexible macrocell structures. CPLDs sit in the hierarchy between simple PLDs and FPGAs: they offer predictable interconnect delays (typically <1 ns per logic block) and boot instantly from on-chip memory, making them ideal for glue logic, bus decoding, and control-plane state machines rather than data-plane DSP or pipelined datapath logic. Key features of the EPM9560RC208-7 include 208 user I/O pins, 16 macrocells arranged in four Logic Array Blocks (LABs), 5 ns tPD combinational delay, and a maximum toggle frequency above 125 MHz. The RQFP-208 package gives designers a robust surface-mount footprint with a thermal resistance suitable for industrial temperature operation, and Altera's MAX+PLUS II development environment supports schematic, VHDL, and Verilog entry. The MAX 9000 family is electrically and pin-compatible across speed grades (-7, -10, -12, -15, -20), so the same PCB can be repopulated with faster or slower parts to balance timing margin against cost. The internal architecture uses a Programmable Interconnect Array (PIA) that routes every LAB signal to every other LAB, eliminating the timing variance that plagues segmented FPGA routing fabrics. Each macrocell contains a programmable AND/OR array followed by a configurable flip-flop with D, T, JK, or SR modes, plus programmable output enable, clear, and preset controls. The 208-pin RQFP delivers 160 mA DC sink current per output, strong enough to directly drive 5V TTL buses and most 3.3V CMOS loads without external buffers. Typical applications include bus bridge decoding on legacy VME/PCI boards, address decoding for 68k and x86 microprocessor systems, glue-logic consolidation on industrial controllers, state-machine replacement on telecommunications backplane cards, and pin-compatible refresh of obsolete discrete logic on factory-automation hardware. Designers also use the EPM9560 as a 'soft glue' companion to an FPGA or microcontroller, absorbing the last few hundred gates of random logic that would otherwise force a board respin. Design consideration: when migrating from the older CQFP-208 ceramic variant, note that the RQFP-208 plastic package has a different thermal resistance and is not hermetically sealed. The Altera Product Discontinuance Notice confirms that the RQFP-208 is form, fit, and functionally equivalent to the ceramic CQFP-208 at all speed grades, so existing footprints accept either package. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
EPM9560RC208-7N - MAX 9000 EPLD, 208-Pin RQFP, 7ns | Intel (Altera)
The Intel (formerly Altera) EPM9560RC208-7N is a member of the MAX 9000 family of Erasable Programmable Logic Devices (EPLDs), built on a 0.65-micron CMOS EEPROM process and supplied in a 208-pin Power Quad Flat Pack (RQFP) surface-mount package. It is part of the long-running MAX 9000 series that targets high-density, high-pin-count glue-logic, state-machine, and bus-interface integration on a single programmable device. The "RC208" suffix indicates the RQFP-208 package, the "7" denotes a 7 ns pin-to-pin propagation delay (speed grade -7), and the trailing "N" indicates a lead-free / Pb-free process node per Altera's ordering code convention. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that retains its configuration in on-chip EEPROM, eliminating the need for an external configuration PROM. The MAX 9000 family sits in the product hierarchy between simple PLDs (PAL/GAL) and SRAM-based FPGAs, combining multi-level AND/OR array logic with macrocell-style I/O and a high pin count for bus-intensive applications. Because it is erasable and reprogrammable, designers can iterate logic without refabricating silicon, which is the core value proposition of programmable logic over fixed-function ASICs. Key features of the EPM9560RC208-7N include high logic density, 208 user I/O pins, in-system programmability through Altera's MAX+PLUS II / Quartus toolchain, and a 7 ns tPD suitable for high-speed decoder, latch, and state-machine functions. The RQFP package supports both commercial and industrial operating ranges and provides ample signal headroom for parallel bus interfaces, address decoding, and FIFO control. Architecturally, the device uses a hierarchical AND/OR plane feeding multiple Logic Array Blocks (LABs) and macrocells, with each macrocell containing a programmable flip-flop, product-term selector, and I/O control. Compared with the smaller MAX 7000 family, MAX 9000 expands usable gates and macrocell count to address wider bus interfaces and larger state machines. Typical applications include peripheral and memory address decoding in 32-bit and 64-bit microprocessor systems, glue logic and bus arbitration in industrial control boards, state-machine controllers in telecom backplane designs, and pin-compatible upgrades for older 24-pin / 84-pin PLD footprints where higher I/O and faster tPD are required. The RQFP-208 package is also favored where fine-pitch surface-mount assembly is acceptable and maximum I/O count is mandatory. When designing in this part, verify the timing model in the MAX 9000 datasheet against worst-case industrial temperature and supply voltage. Because this is an EEPROM-based legacy device, long-term availability must be confirmed with the manufacturer before new design-in; for new designs consider Altera/Intel MAX II, MAX V, or MAX 10 CPLDs as modern migration paths. This page synthesizes distributor stock observations, drop-in alternative candidates, and practical design notes that complement (not duplicate) the original MAX 9000 datasheet.
EPM9560RC208-9 - MAX 9000 CPLD, 560 Macrocells, 208-RQFP | Altera
The Altera EPM9560RC208-9 is a high-density MAX 9000 family Complex Programmable Logic Device (CPLD) delivering 560 macrocells, 12,000 usable gates, and a 9 ns pin-to-pin propagation delay in a 208-pin RQFP power quad flat pack package. It belongs to the mature MAX 9000 EPLD family, originally released by Altera and now supported through Intel's legacy programmable logic portfolio after the 2015 acquisition. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks with a central interconnect matrix, offering deterministic timing, instant-on behavior, and high-drive I/O. The MAX 9000 family sits in the CPLD taxonomy as: CPLD -> EPLD -> MAX series -> MAX 9000 -> non-volatile flash/EPROM-based logic. Compared to FPGAs, CPLDs typically have lower logic density but faster, more predictable I/O-to-I/O timing and zero configuration delay, making them ideal for glue logic, bus interfacing, and control state machines. Key features of the EPM9560RC208-9 include 560 macrocells organized across 16 Logic Array Blocks (LABs), 212 user I/O pins, in-system programmability via JTAG, and a 5 V tolerant core with multi-voltage I/O support. The 9 ns tPD makes it suitable for high-speed control paths, while the 208-pin RQFP footprint provides generous I/O for bus-intensive designs. Per the Altera datasheet, all EPM9560 devices in the 208-pin RQFP are form, fit, and functionally equivalent to the older 208-pin CQFP variant that Altera has officially discontinued. Typical applications include telecommunications line cards, industrial control and instrumentation, address decoding and bus interfacing, peripheral glue logic in microprocessor systems, and legacy hardware refresh designs where the original Altera toolchain (MAX+PLUS II or Quartus) must be preserved. The wide I/O count also suits parallel data-path bridging and FIFO control logic. When designing with this part, note that the -9 speed grade provides moderate performance suited to control-plane rather than high-speed datapath use. Engineers migrating to newer Intel MAX II / MAX V CPLDs should evaluate pin-count and voltage requirements; the MAX 9000 is 5 V core and is not directly compatible with MAX V's 3.3 V core footprint. A 9 ns tPD corresponds to roughly 110 MHz internal performance, which is appropriate for most glue-logic and control applications but not for high-speed serial interfaces. This page synthesizes distributor stock data, package-equivalent speed-grade alternatives from the same EPM9560 family, and design considerations drawn from the MAX 9000 datasheet family - information not consolidated in any single manufacturer or distributor source.
EPM9560RC210-20 - MAX 9000 CPLD 560 Macrocells | Altera
The Altera EPM9560RC210-20 is a high-density member of the MAX 9000 family of Complex Programmable Logic Devices (CPLDs), delivering approximately 560 macrocells (12,000 usable gates) in a 210-pin Power Quad Flat Pack (RQFP) package with -20 speed grade. The MAX 9000 family is Altera's first-generation high-density CPLD family built on a 0.65um EEPROM process, combining the non-volatility of EPROM with in-system programmability via the Altera MAX+PLUS II development environment. The -20 suffix denotes a 20ns pin-to-pin propagation delay (tPD) for combinational logic at room temperature, making it suitable for glue-logic and high-volume state-machine replacement in cost-sensitive industrial designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL spld devices and high-density FPGAs in the programmable logic hierarchy: PAL/GAL < CPLD < FPGA. CPLDs are characterized by deterministic timing (predictable tPD regardless of routing), instant-on operation (no boot PROM required), and on-chip EEPROM/flash configuration memory. Compared to FPGAs, CPLDs typically offer lower logic density but more predictable timing, lower pin-to-pin delay, and higher suitability for bus-interface, address-decoding, and control-logic applications. The MAX 9000 family extends classic MAX architecture to higher densities, targeting designs previously served only by gate arrays or FPGAs. Key features of the EPM9560RC210 include 560 macrocells organized in 16 Logic Array Blocks (LABs) with 36 macrocells per LAB, a maximum of 212 user I/O pins (package-dependent), 5V tolerant I/O on the 5V variant, and JTAG-compliant IEEE Std 1149.1 boundary-scan support for board-level testability. The device operates from a single 5V supply (VCCINT and VCCIO combined or split depending on revision). Per Altera's MAX 9000 datasheet, tPD is rated at 20ns for the -20 speed grade and the global clock-to-output time tCO is 12ns. The architecture is built around an Enhanced Programmable Logic Element (EPLE) that supports both combinational and registered logic with separate clear, clock-enable, and preset controls per macrocell. Typical applications for the EPM9560 include industrial control glue logic, peripheral bus interfacing (ISA/PCI bridge logic), address decoding for 8/16/32-bit microcontrollers, state-machine replacement in telecom and instrumentation, and high-density glue logic between microprocessors and memory. It is also commonly used in legacy designs that require migration from multiple 74LS/74F discrete PLD chips into a single device while preserving board form factor. When designing with the EPM9560RC210-20, pay attention to the 5V supply ramp requirements and use the Altera MAX+PLUS II or Quartus legacy support flow for fitting. The 210-pin RQFP package requires careful PCB layout - use a 0.5mm pitch footprint with adequate thermal copper pour for reliability. For new designs, consider the MAX II or MAX V families which offer lower power and higher density, but the EPM9560 remains in service for legacy long-life-cycle industrial, aerospace, and military programs.
EPM9560RC240-10 - MAX 9000 CPLD 560 Macro Cells | Altera
The Altera EPM9560RC240-10 is a MAX 9000 family Complex Programmable Logic Device (CPLD) offering 12,000 usable gates and 560 macro cells with a 10 ns pin-to-pin propagation delay, housed in a 240-pin RQFP (PowerQuad) package. It operates from a 5 V supply and supports system clock frequencies up to 144.9 MHz. A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines the flexibility of an FPGA with the non-volatile, instant-on simplicity of a PAL. CPLDs sit between simple glue logic and full FPGAs in the programmable logic hierarchy: they offer deterministic timing, single-chip integration of bus interfaces and state machines, and no external configuration memory. The MAX 9000 family extends this concept with multiple interconnected logic array blocks (LABs) and a programmable interconnect array, delivering FPGA-like density with CPLD-like predictability. The EPM9560RC240-10 provides 560 macro cells organized into 12 LABs, each containing 16 macrocells, plus 12 dedicated input/GCLK pins and 4 dedicated input pins. Its 10 ns propagation delay (the '-10' speed grade) makes it suitable for bus-interface and control-path logic where deterministic timing matters more than raw density. The 240-pin RQFP package exposes up to 192 user I/O pins, enabling wide bus widths without external multiplexing. Architecturally, the MAX 9000 uses CMOS EEPROM technology, giving the device non-volatile configuration that is live immediately at power-up - no boot PROM or configuration controller is required. This makes it attractive for industrial control, instrumentation, and legacy telecom boards where instant-on operation and long-term availability are priorities. The 5 V core and I/O simplify interfacing to legacy TTL/CMOS peripherals without level shifters. Typical applications include PCI and ISA bus bridging, memory controllers, state-machine sequencing, address decoding, and glue logic consolidation in industrial and telecom equipment. The device is widely used as a drop-in replacement for discrete 74-series logic in existing 5 V designs. When designing with the EPM9560RC240-10, note that it is a 5 V-only device - it cannot be used in 3.3 V or lower systems without level translation. Also confirm programming support: MAX 9000 devices require a compatible device programmer and the MAX+PLUS II toolchain, which is no longer actively developed by Intel/Altera. This page synthesizes distributor availability, drop-in alternatives from the same MAX 9000 family, and practical design notes that go beyond the manufacturer datasheet, helping engineers evaluate the EPM9560RC240-10 for legacy and long-lifecycle designs.
EPM9560RC240-10N - MAX 9000 CPLD 560 Macrocells 5V 240-Pin RQFP | Intel
The Intel (formerly Altera) EPM9560RC240-10N is a high-density CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 family, delivering 12,000 usable gates, 560 macrocells, and 16 Logic Array Blocks (LABs) in a 240-pin RQFP (Plastic Quad Flat Pack) package. According to the Altera MAX 9000 datasheet, this device operates from a 5.0 V supply, supports an internal operating frequency of 144.9 MHz, and offers a pin-to-pin propagation delay of 10 ns (the "-10" speed grade suffix), making it suitable for high-performance glue-logic, bus-interface bridging, and state-machine consolidation tasks. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single die, connected through a programmable interconnect matrix (the Multiple Array MatriX, or MAX, architecture). The MAX 9000 family is Altera's third-generation MAX architecture and represents the high-density tier above MAX 7000, sitting hierarchically between simple PLDs and FPGAs in the programmable-logic taxonomy: PLD -> CPLD -> MAX architecture -> high-density CPLD -> programmable logic. CPLDs are typically chosen when deterministic timing, instant-on non-volatile configuration, and high fan-in are required. Key features of the EPM9560RC240-10N include 212 user I/O pins (the package's pin budget after subtracting dedicated supply, JTAG, and configuration pins), in-system programmability (ISP) through a standard 4-pin JTAG (IEEE 1149.1) interface, and 5.0 V in-system programmability (the "N" suffix denotes lead-free / Pb-free finish per industry convention). The device is built on a 0.65 µm CMOS EEPROM process, retains its configuration without external memory, and supports multi-voltage I/O operation, allowing it to interface directly with 3.3 V and 5.0 V logic without external level shifters. The MAX 9000 architecture integrates a global programmable interconnect array called the Programmable Interconnect Array (PIA) that routes signals between LABs, each of which contains 16 macrocells. Each macrocell embeds a programmable flip-flop, product-term selection logic, and a configurable I/O architecture. Designers typically use MAX 9000 devices for high-pin-count bus multiplexing, address decoding, and asynchronous state machines where the deterministic 10 ns propagation delay of the -10 speed grade enables precise timing closure. Typical applications include industrial control and factory automation backplanes, telecommunications line-card glue logic, military and aerospace systems requiring radiation-tolerant EEPROM-based logic, and legacy 5 V system designs in test-and-measurement equipment. The wide I/O count (212 user I/Os) makes it a strong fit for bus-bridging applications that connect legacy microprocessors (8086, 68k, MIPS) to modern peripherals, or for parallel data-acquisition front-ends where many TTL-level signals must be latched and processed. When designing with this device, ensure the JTAG chain is correctly terminated with the TCK return path and that the 5.0 V supply rail has adequate decoupling (typically 0.1 µF per supply pin plus a bulk 10 µF tantalum). Designers should also note that MAX 9000 devices are mature, mature-lifecycle products - verify current Altera/Intel support status and lead times before starting a new design.

EPM9560RC240-12 - 560 Macrocell EE PLD, 12ns PQFP-240 | Altera
The Altera EPM9560RC240-12 is a high-density Erasable-Electronic Programmable Logic Device (EE PLD) from the MAX 9000 family, featuring 560 macrocells, 772 flip-flops, and 191 user I/O lines housed in a 240-pin Plastic Quad Flat Pack (PQFP) package. The -12 speed grade corresponds to a 13.4 ns pin-to-pin propagation delay through the logic array, supporting system clock frequencies up to approximately 76 MHz in registered designs. The part operates from a 5V core supply with 3.3V or 5V tolerant I/O via configurable I/O banks, enabling mixed-voltage interfacing with legacy TTL, modern CMOS, and LVTTL peripherals on the same PCB. A Programmable Logic Device (PLD) is a non-volatile digital integrated circuit whose logic function is defined after manufacture by the end user via an EEPROM or SRAM-based configuration cell matrix. EE PLDs retain their configuration when power is removed, which distinguishes them from SRAM-based FPGAs that require a boot PROM. Within the broader taxonomy, the MAX 9000 family occupies the high-density CPLD (Complex PLD) tier - sitting between simple SPLDs/GALs and full FPGAs - and is engineered for glue-logic integration, bus interfacing, state-machine consolidation, and peripheral decoding in systems where non-volatility and deterministic timing matter more than raw gate count. Key features of the EPM9560RC240-12 include 12 ns combinatorial tPD, in-system programmability via the IEEE 1149.1 JTAG interface, 191 high-drive I/O pins organized in I/O banks with per-pin slew-rate and pull-up control, and an operating junction temperature range suitable for commercial and industrial environments. The device supports the Altera MAX+PLUS II and Quartus design flows, allowing legacy MAX-series designs to be ported without HDL rewrites. The MAX 9000 architecture combines a Logic Array Block (LAB) fabric with a programmable interconnect array (PIA), giving uniform propagation delay across all LAB-to-LAB paths. Each macrocell contains a programmable flip-flop with D, T, JK, or SR modes, plus product-term sharing logic, which makes the family efficient for wide combinatorial decoders and registered state machines rather than pipelined datapath work. Typical applications include peripheral bus decoding in PCI/ISA bridge designs, address decoding for DSP and microcontroller subsystems, register-bank expansion in telecom backplane glue logic, and industrial control PLCs where deterministic timing and non-volatile configuration are required. The wide I/O count also makes the EPM9560 useful for legacy test equipment and instrumentation front ends. Designers should note that the EPM9560RC240 series is now considered a mature / legacy device family by Altera (now Intel FPGA), with -12, -15, and -20 speed grades typically available on the distributor surplus market rather than as fully production-stocked parts. New designs should consider MAX II or MAX V CPLDs as pin-compatible modern alternatives where possible.

EPM9560RC240-15 - MAX 9000 CPLD 560 Macro Cells | Intel
The Intel (Altera) EPM9560RC240-15 is a MAX 9000 family Complex Programmable Logic Device (CPLD) with 560 macrocells, 12,000 usable gates, and 191 user I/O pins, housed in a 240-pin RQFP (PowerQuad/FPQFP) package. It operates from a 5.0 V supply and delivers a 15 ns pin-to-pin propagation delay, making it a classic glue-logic and bus-interface solution for legacy 5 V systems. A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix, allowing designers to implement custom combinational and sequential logic without fabricating an ASIC. Within the programmable logic hierarchy, a CPLD sits between simple PLDs (PAL/GAL) and FPGAs: it offers non-volatile configuration, deterministic timing, and instant-on operation, which makes it ideal for power-up sequencing, address decoding, and bus bridging. The MAX 9000 family is built on Altera's third-generation Multiple Array MatriX (MAX) architecture using CMOS EEPROM technology, so the configuration is retained without an external boot device. Key features include 560 macrocells organized into logic array blocks, 12,000 usable gates, 191 user I/O pins, in-system programmability (ISP) via the JTAG interface, and a maximum internal frequency of 145 MHz. The 15 ns pin-to-pin delay provides predictable, race-free timing that is essential for combinatorial address decoding and handshake logic in microprocessor systems. The device uses 5.0 V CMOS technology with EEPROM-based configuration, giving it high noise immunity and direct compatibility with 5 V TTL/CMOS logic levels. Its 240-pin RQFP package with exposed pad supports surface mounting and provides 191 I/O for wide bus interfaces. The commercial temperature grade covers 0 C to 70 C. Typical applications include legacy microprocessor glue logic, ISA/PCI bus interface logic, industrial control backplanes, telecom line-card control, test and measurement instrumentation, and FPGA companion logic. The EPM9560RC240-15 is widely used as a drop-in replacement in existing MAX 9000 designs and for sustaining long-lifecycle industrial and defense systems. When designing with this device, note that it is a 5 V-only part and is not 3.3 V tolerant on all pins; level shifting is required when interfacing with modern low-voltage logic. Also confirm programming support, as MAX 9000 devices require a compatible JTAG programmer and the vendor's legacy programming software. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate the EPM9560RC240-15 for legacy and long-lifecycle designs.
