EPM7512BFI256-7 - MAX 7000B CPLD, 512 Macrocells, 256-FBGA | Intel
The Intel (formerly Altera) EPM7512BFI256-7 is a high-performance, 2.5-V CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000B family, packaged in a 256-ball FineLine BGA (FBGA-256) with 212 user I/Os. It integrates 512 macrocells (equivalent to 10,000 usable gates), runs at a maximum internal frequency of 164 MHz, and offers a pin-to-pin propagation delay of 7.5 ns (the "-7" speed grade). The device is built on Altera's second-generation Multiple Array Matrix (MAX) architecture, which provides predictable, deterministic timing and in-system programmability via IEEE 1149.1 JTAG. A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EEPROM-based programmable logic IC that contains multiple PAL-like macrocell blocks interconnected by a central programmable interconnect matrix. The MAX 7000 family sits between small SPLDs (PAL/GAL) and large FPGAs: it offers fast, deterministic combinational and sequential logic with instant-on capability and zero-configuration boot time, making it ideal for glue logic, bus interfacing, and power-sequencing tasks where an FPGA would be over-specified and too expensive. The "B" suffix denotes the 2.5-V core generation with multi-volt I/O (1.8 V/2.5 V/3.3 V tolerant), and the "I" suffix in the part number indicates the industrial temperature grade (-40 °C to +105 °C). Key features of the EPM7512BFI256-7 include 512 macrocells, 212 user I/Os, 5.5 ns–7.5 ns propagation delay (depending on grade), 164 MHz internal frequency, and JTAG-compliant in-system programming. The SameFrame pin-out feature shared by all 0.8-mm-pitch Ultra FineLine BGA devices in this family allows designers to migrate across densities (e.g., EPM7128 / EPM7160 / EPM7192 / EPM7256 / EPM7512) on the same PCB footprint. Per Altera's MAX 7000 datasheet, all members of this family share the same Quartus/MAX+PLUS II toolchain, JTAG programming interface, and I/O standards including LVTTL, LVCMOS, PCI, and SSTL. Architecturally, the EPM7512BFI256-7 contains 16 Logic Array Blocks (LABs) of 16 macrocells each, a programmable interconnect array (PIA), and four I/O pins per macrocell block. Each macrocell contains a programmable AND/OR array, a flip-flop, and product-term allocation logic, supporting up to 32 product terms per macrocell with expander terms. The EEPROM-based configuration cell provides non-volatile storage with 100+ program/erase cycles per the device datasheet. Typical applications include bus-interface bridging (e.g., 8/16/32-bit address decoding), power-up sequencing for multi-rail systems, peripheral glue logic in telecom line cards, industrial PLC I/O expansion, and replacement of multiple 74-series TTL/CMOS logic gates in cost-down board designs. The 212 user I/Os also suit LED-driver multiplexing and high-density state-machine controllers. When designing with the EPM7512BFI256-7, ensure the 0.8 mm-pitch BGA is mounted with appropriate PCB fabrication tolerances and that all unused I/Os are left floating or tied per the datasheet recommendation. Decoupling should follow Altera's reference design: 0.1 µF + 10 µF bulk capacitors placed within 100 mil of each supply pin. For migration, the SameFrame pin-out allows drop-in to EPM7256BFI256-7 (256 macrocells) and to EPM7192BFI256-7 (192 macrocells) on the same 256-ball footprint.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a central interconnect matrix. CPLDs sit between simple SPLDs and FPGAs in the programmable-logic hierarchy, providing fast, deterministic pin-to-pin timing (no boot time), instant-on operation, and EEPROM- or flash-based configuration that retains the bitstream across power cycles. The MAX 7000B family specifically is built on a 2.5 V CMOS EEPROM Multiple Array Matrix (MAX) architecture and was designed as a glue-logic replacement for multiple 74-series TTL parts. Key features of the EPM7512BQC208-10 include 32 Logic Array Blocks (LABs) of 16 macrocells each, four pin-to-pin output enable signals, in-system programmability through a JTAG-compliant IEEE Std. 1149.1 interface, and a commercial operating temperature grade of 0 to +70 degrees C. The device operates from an internal 2.5 V core supply (2.375 V to 2.625 V) and is supported by the legacy Altera MAX+PLUS II and Quartus II design software. Architecturally, the MAX 7000B device uses a second-generation MAX architecture with a programmable interconnect array (PIA) that routes signals between LABs. Each macrocell contains a programmable AND/OR array, a flip-flop, and configurable I/O architecture supporting JTAG boundary-scan testing, which simplifies board-level test in production. The -10 speed grade places this part at the slower end of the MAX 7000B range, trading off fmax for reduced cost and easier timing closure in glue-logic applications. Typical applications include bus-interface bridging, address decoding, state-machine control, peripheral glue logic, industrial I/O expansion, and legacy 5 V/3.3 V system interfacing where the MAX 7000B I/O tolerance is required. The 176 user I/O count is generous for replacing many discrete 74LS/74HC packages with a single device. When designing, note that the EPM7512BQC208-10 is part of the mature MAX 7000B line: many MAX 7000B variants are now NRND or EOL, so check the latest lifecycle status before committing to a new design. The 208-pin PQFP package requires careful PCB layout, with thermal and high-speed signal-integrity considerations; XAIPART can cross-reference compatible MAX 7000B speed grades (e.g., -7, -10, -12, -15) that share this PQFP-208 footprint.

The MAX 7000B family is the 2.5 V evolution of the industry-standard MAX 7000 architecture. Key features include 512 macrocells organized into 16 logic array blocks, 176 user I/O pins, a 163.9 MHz internal frequency (5 ns tPD), and EEPROM configuration that retains the design without power. The 2.5 V core reduces dynamic power versus 5 V MAX 7000S devices, and the device supports IEEE 1149.1 JTAG boundary-scan for in-system programming and board-level test. The MAX 7000B architecture uses a programmable interconnect array (PIA) to route all logic signals, giving fully deterministic pin-to-pin delays independent of routing. Each macrocell provides a flip-flop with individual clock, clear, and preset, plus programmable output slew-rate and open-drain options. The 208-pin PQFP package provides 176 I/O with a 0.5 mm lead pitch. Typical applications include PCI/ISA bus glue logic, DSP and microcontroller interface logic, memory controllers, and industrial control state machines. The 5 ns delay and 163.9 MHz operation suit address decoding and handshake logic where predictable timing matters more than raw gate count. When designing with this device, note that the -5 speed grade is the fastest MAX 7000B grade and that the 2.5 V core requires level-compatible I/O planning for 3.3 V or 5 V peripherals.

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. CPLDs sit between simple SPLDs (e.g. PAL/GAL) and larger FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA -> programmable logic -> digital IC -> semiconductor. The MAX 9000 architecture targets high-density glue logic, bus-interface bridging, and state-machine control with deterministic timing that is critical for system-level design. Key features include 320 macrocells (organized across 16 Logic Array Blocks, LABs), 16 dedicated inputs, 52 I/O pins in the 84-PLCC, and PCI Local Bus Specification Revision 2.2 compliance for the -10 speed grade. Each macrocell contains a programmable register with configurable Product-Term allocation, allowing wide combinational and registered logic functions. The 5.0-V ISP interface enables board-level programming via JTAG, eliminating socketed pre-programmed parts and supporting field upgrades.

Configuration is loaded via JTAG using a ByteBlaster or compatible programmer, and the part can be reprogrammed thousands of times. The 10 ns tPD and 144.9 MHz fCNT make this part suitable for state machines running at moderate clock rates and for pipelined control logic. Typical applications include legacy industrial control boards, telecom line-card glue logic, address-decoding and chip-select generation, peripheral bus interfacing (ISA, PCI, VME), motor-control state machines, and retrofit/repair scenarios where the original MAX 9000 part must be replaced. The part is also widely used in educational boards, prototype development, and military/aerospace systems where the MAX 9000 family has long design-cycle approval. When designing with the EPM9320ALC84-10N, observe the recommended 5.0 V VCC tolerance (the A-suffix denotes 5 V operation, not the 3.3 V-compatible LC/RC/QI variants). Decouple each VCC/ground pair with a 0.1 F ceramic capacitor placed within 50 mils of the package pin, and adhere to the JTAG chain layout guidelines for multi-device boundary-scan configurations. The 84-PLCC socket should be a low-profile machine-pin or open-frame type rated for the operating temperature range.

The device supports IEEE Std 1149.1 JTAG boundary-scan, in-system programming via the JTAG port, and a power-down feature that minimizes standby consumption. The 84-pin PLCC package is through-hole-friendly and easy to hand-prototype, which is one of the reasons this part remains specified in long-lifecycle industrial controllers. Architecturally, the EPM9320ALC84-15 uses Altera's classic MAX architecture with EEPROM-based configuration cells, a programmable AND array feeding a fixed OR array, and per-macrocell flip-flops with programmable polarity. The interconnect is a continuous, fast-path switch matrix that delivers uniform 16 ns delays across all pins regardless of placement, which is the principal reason designers choose this family over look-alike FPGAs for control-plane logic. Typical applications include 5 V industrial PLC glue logic, ISA/PCI bus address decoding, motor-control state machines, telecom backplane control, and legacy ASIC replacement in medical and aerospace systems. Designers should also evaluate the EPM9320ALC84-10 (10 ns tPD) when margin is tight, or migrate to MAX II or MAX V CPLDs if lower power is required. When designing with the EPM9320ALC84-15, pay particular attention to the global clock and clear pin assignments and ensure that the JTAG chain is correctly ordered in multi-device boards. The device requires a single 5 V supply and supports ISP via JTAG; an external configuration PROM is not required.

The MAX 9000 family delivers 320 to 560 macrocells across multiple device options, fabricated on a 0.5 µm CMOS EEPROM process. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/GALs and high-density FPGAs in the programmable logic hierarchy. CPLDs use a classic AND/OR PLA-style architecture with non-volatile EEPROM or flash configuration cells, providing instant-on operation at power-up with no external boot memory. In the broader taxonomy, the EPM9320 belongs to: CPLD -> programmable logic -> logic IC -> semiconductor device, and is positioned as the high-density endpoint of the Altera MAX legacy families that preceded the modern MAX II, MAX V, and MAX 10 device series. Key features of the EPM9320ALC84-20 include 320 macrocells, 16 logic array blocks (LABs), 212 user I/O pins, and a worst-case commercial-grade tPD of 20 ns through the Logic Array Blocks and Programmable Interconnect Array (PIA). The device supports 5.0 V in-system programmability via the IEEE 1149.1 JTAG interface and includes built-in JTAG boundary-scan test circuitry. The PLCC-84 package offers a JEDEC-standard 84-pin ceramic/leaded footprint with a 1.27 mm pitch. Architecturally, the EPM9320 employs the classic MAX 9000 multi-LAB structure, where each LAB contains 16 macrocells with configurable flip-flops, expanders, and product-term allocation. The Programmable Interconnect Array (PIA) provides deterministic, predictable routing with no contention, making the device well suited for asynchronous and clocked state-machine designs requiring fixed timing. Typical applications include legacy telecommunications backplane glue logic, industrial PLC I/O expansion and protocol bridging, military/aerospace systems requiring instant-on programmable logic, and drop-in replacement of multiple 74LS/74F discrete logic packages. The instant-on, non-volatile nature of MAX 9000 makes it especially attractive in deterministic boot scenarios where FPGAs would require an external configuration ROM.

The Intel (formerly Altera) EPM9320ALI84-10 is a high-performance CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 family, fabricated on an advanced CMOS technology. The device provides 6,000 to 12,000 usable gates, pin-to-pin delays as fast as 10 ns, and counter speeds of up to 144 MHz, all housed in an 84-pin PLCC package. It delivers 320 macrocells and is supported by 5.0-V in-system programmability (ISP) through a built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface. A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single die with a programmable interconnect matrix, sitting hierarchically between simple SPLDs/CPLDs and FPGAs in the programmable logic taxonomy: SPLD < CPLD < FPGA < programmable logic < semiconductor. The MAX architecture specifically uses a Multiple Array MatriX (MAX) interconnect that delivers predictable timing, a critical advantage over SRAM-based FPGAs for glue-logic and bus-interface roles where deterministic propagation delay matters. Key specifications of the EPM9320ALI84-10 include 320 macrocells, 84 user I/O pins, 10 ns pin-to-pin combinatorial delay (Tpd1), 144 MHz maximum counter frequency, and 5.0V VCC operation. The device also features four dedicated inputs, JTAG boundary-scan test compliance per IEEE 1149.1, and an industrial operating temperature range of -40C to +85C suitable for harsh environments. Architecturally, the MAX 9000 family integrates PAL-like logic array blocks (LABs) with a high-speed programmable interconnect array (PIA). The EEPROM process technology provides non-volatile configuration that retains the design pattern through power cycles without an external boot PROM, simplifying board design and reducing bill-of-materials cost. Typical applications include high-speed bus interfacing and address decoding in embedded systems, peripheral glue logic in telecommunications equipment, industrial control system logic integration, and replacement of multiple discrete 22V10/PAL/GAL devices in legacy board designs. The deterministic timing also makes it suitable for state-machine controller and protocol-bridge implementations. When designing with this part, note that -10 grade denotes 10 ns tpd; slower (-15, -20) and faster (-7) grades are available as pin-compatible drop-in replacements within the same 84-PLCC footprint. ISP via JTAG requires a 5V-tolerant TCK/TMS/TDI/TDO chain wired to a programming header or boundary-scan controller.

The Altera EPM9320ALI84-10N is a high-density, in-system-programmable Complex Programmable Logic Device (CPLD) from the MAX 9000 family, delivering 320 macrocells, 20 Logic Array Blocks (LABs), and 6,000 to 12,000 usable gates in a 5.0-V CMOS EEPROM-based architecture. Housed in an 84-pin PLCC (Plastic Leaded Chip Carrier) package with J-bend terminals on a 1.270 mm pitch, this device offers pin-to-pin delays as fast as 10 ns and counter speeds up to 144 MHz, making it suitable for high-performance glue-logic, bus-interface, and state-machine applications. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocells with a central interconnect matrix. In the system hierarchy, the CPLD sits between simple SPLDs (PAL/GAL) and FPGAs: it offers deterministic 10 ns timing, instant-on EEPROM configuration, and high I/O count, but lacks the fine-grained LUT fabric of an FPGA. The MAX 9000 family implements Altera's third-generation Multiple Array MatriX (MAX) architecture, which groups macrocells into LABs joined by a programmable interconnect array (PIA), enabling predictable timing and efficient state-machine implementation. Key features of the EPM9320ALI84-10N include 56 user I/O pins, separate VCCINT (5.0 V) and VCCIO pins for output-driver voltage selection (3.3 V or 5.0 V), and built-in IEEE Std. 1149.1 JTAG interface for in-system programmability (ISP). The device supports TTL-compatible inputs at 5.0-V VCCINT and offers multi-voltage I/O for mixed-voltage designs. Programmable power reduction modes lower quiescent current during standby, while the -10 speed grade delivers the fastest pin-to-pin delay in the MAX 9320 die family. The MAX architecture uses EEPROM configuration memory, which provides non-volatile storage and infinite re-programmability without external boot devices. The 320 macrocells are split into 20 LABs of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and configurable I/O control. This organization is optimized for wide combinatorial and registered logic functions typical of address decoding, bus arbitration, and asynchronous state-machine designs. Typical applications include high-performance bus-interface and address decoding in microprocessor systems, peripheral glue logic in telecom and networking equipment, industrial control and instrumentation logic, and replacement of multiple discrete TTL/CMOS MSI parts on legacy PCBs. The 84-pin PLCC package and through-hole-compatible socket footprint also make the EPM9320ALI84-10N a common choice for legacy industrial and military designs that require hand-reworkability. When designing with the EPM9320ALI84-10N, ensure that VCCINT is always tied to 5.0 V, while VCCIO can be set to 3.3 V or 5.0 V depending on the I/O rail. Use the JTAG interface for in-system re-programmability and boundary-scan testing, and observe the maximum I/O current ratings per bank to avoid output-buffer overheating. The -10 speed grade has the highest dynamic ICC; for lower-power designs, consider the slower -12 or -15 grades in the same MAX 9320 die family. This page synthesizes the manufacturer datasheet, current distributor stock levels, drop-in alternatives drawn from the same MAX 9000 family and competitor CPLD lines, and practical PCB design guidance not found in a single manufacturer document - information gain targeted at engineers maintaining or upgrading legacy 5 V MAX 9000 designs.

Architecturally, the MAX 9000 device uses an enhanced EPLD architecture with multiple LABs interconnected by the Programmable Interconnect Array (PIA). Each LAB contains 16 macrocells, each with a programmable AND/OR array, configurable flip-flop, and I/O architecture. The non-volatile EEPROM configuration cell provides instant-on behavior at power-up with no external configuration PROM required, distinguishing MAX 9000 from SRAM-based FPGAs and giving it deterministic boot for critical control paths. Typical applications include high-speed bus decoding and address mapping, peripheral interfacing and glue logic in microprocessor systems, state-machine control, fast datapath multiplexing, JTAG-driven board-level test integration, and legacy 5 V system logic consolidation. Designers select this part when they need fast deterministic pin-to-pin delays combined with non-volatile instant-on configuration. When designing with the EPM9320ARC208-10N, ensure VCC rises monotonically during power-up, place decoupling capacitors (0.1 uF plus bulk) close to every VCC pin, and respect the input undershoot/overshoot limits (transitions may undershoot to -2.0 V or overshoot to 7.0 V only for periods under 20 ns at no-load). Use the JTAG chain to program in-system; the open-drain JTAG pin requires an external pull-up.

Its 10 ns combinatorial propagation delay and 134 MHz internal counter frequency make it suitable for high-speed control logic, address decoding, and bus arbitration in systems built around microprocessors, microcontrollers, or DSPs. The part is fabricated on a 0.7 µm CMOS EEPROM process, supplied in a 84-pin PLCC package (JEDEC outline MO-047), and is RoHS/RoHS3 compliant per the modern Intel material declaration. The pinout follows the standard MAX 9000 PLCC-84 assignment, and the device is supported by legacy Altera development tools (MAX+PLUS II and Quartus MAX device support). It is widely used in legacy industrial controllers, telecom line cards, test instruments, and aerospace systems where the design was qualified decades ago and the same part must be sourced for ongoing production or repair. Typical applications include 32-bit address decoding for embedded CPU boards, IEEE-1284 parallel-port peripherals, ISA/PCI bus interface glue logic, programmable keyboard/video/mouse controllers, and digital state machines in industrial PLCs. The instant-on non-volatile configuration means no boot time and no bitstream loader, which is a decisive advantage over SRAM FPGAs in deterministic boot-critical systems. When designing with this part, note that the EPM9320LC84-10 is a long-lifecycle legacy device. Most original Altera MAX 9000 variants have been migrated to lead-free or lead-bearing packages, and the part is sourced primarily through distributors holding legacy stock or through independent distributors. Always verify the date code and traceability documents before placing the part into a new design, and consider the modern MAX II / MAX V families for new designs unless pin/footprint compatibility with EPM9320LC84-10 is mandatory.

It features a 15 ns maximum propagation delay (tPD) and operates from a 5.0 V supply (4.75 V to 5.25 V), supporting 5.0 V in-system programmability (ISP) through a built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface for boundary-scan test and on-board reconfiguration. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines the instant-on characteristics of classic PAL/GAL architectures with the density of modern FPGAs. The MAX architecture organizes logic into Logic Array Blocks (LABs) interconnected by a programmable interconnect matrix, with each macrocell containing a product-term array, a programmable flip-flop, and configurable I/O steering - placing CPLDs in the hierarchy: macrocell -> LAB -> CPLD -> programmable logic -> semiconductor device. The EPM9320LC84-15 supports a maximum clock frequency of 117.6 MHz and provides up to 212 user I/O pins in the largest package of the family. Its pin-locking architecture ensures that any change to the user's logic design does not alter pin assignments, simplifying PCB layout and design migration. The device also supports JTAG-based IEEE 1149.1 boundary-scan testing and includes built-in pull-up resistors on every I/O for reliable tri-state bus interfacing. Typical applications include bus interface bridging (PCI-to-ISA, address decoding), peripheral glue logic, state-machine controllers, and high-performance control logic replacement for multiple SSI/MSI components. Designers commonly deploy the EPM9320LC84-15 in telecom backplane controllers, industrial automation I/O expanders, and legacy system upgrades where 5 V tolerant logic and deterministic 15 ns timing are required. When designing with this device, ensure VCC ramps monotonically between 4.75 V and 5.25 V per the operating requirements; undershoot below -0.5 V or overshoot above 7.0 V on I/O pins (under no-load conditions, for periods shorter than 20 ns) is permissible only during fast transitions. Decoupling with 0.1 microfarad and 10 microfarad capacitors adjacent to every VCC pin is recommended.

It is built on Altera's third-generation Multiple Array MatriX (MAX) architecture, providing 16 ns pin-to-pin propagation delay and an internal counter frequency of up to 118 MHz (also referenced at 144 MHz in some vendor sources). The device operates from a single 5.0 V supply and supports in-system programmability (ISP) via the IEEE Std. 1149.1 JTAG interface. 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 programmable interconnect network. CPLDs sit in the hierarchy between simple PLDs (PAL/GAL) and FPGAs, offering deterministic timing, instant-on configuration from on-chip EEPROM, and high pin-to-pin logic density. They are commonly used for glue logic, address decoding, bus interface bridging, and state machine implementation where predictable timing and zero-configuration-boot behavior are required. Key features of the EPM9320LC84-20 include four dedicated low-skew global input pins (typically used for clock, clear, and output enable), dual-output macrocells that allow independent use of combinatorial and registered logic, and PCI Local Bus Specification Revision 2.2 compliance for 33 MHz PCI designs. The 5.0 V core and I/O supply, combined with JTAG-based ISP, makes it well suited for legacy industrial backplanes and telecom infrastructure where 3.3 V-only FPGAs cannot be used. The MAX 9000 architecture divides the device into Logic Array Blocks (LABs) interconnected by the Programmable Interconnect Array (PIA). Each macrocell contains a programmable AND/OR array, a configurable flip-flop, and product-term allocation logic, allowing wide fan-in functions to be implemented efficiently. The EPM9320 derivative is the second-largest member of the family, providing approximately 12,000 usable gates. Typical applications include PCI bus interface controllers, peripheral address decoding in 5 V microprocessor systems, industrial control glue logic, telecom line-card control planes, and replacement of multiple discrete PAL/GAL devices. The 0 to 70 C commercial temperature range suits enclosed indoor equipment such as base stations, factory controllers, and test instrumentation. When designing with this part, observe the 5.0 V I/O requirement and ensure all driven signals are 5 V tolerant at the receiver. The 84-pin PLCC socket allows easy prototyping but consumes more board area than equivalent QFP packages; consider the EPM9320RC208 or EPM9320GC280 variants if board space is constrained.

Operating from a 5 V supply with a propagation delay of 16 ns (tPD) and an internal frequency up to 118 MHz, this device targets glue-logic, bus-interface, and state-machine consolidation in industrial and commercial systems. According to the manufacturer datasheet, the -20 speed grade corresponds to a 16 ns pin-to-pin delay, placing this part in the standard-performance tier of the MAX 9000 lineup. 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 centralized interconnect matrix. The MAX 9000 architecture represents Altera's third-generation Multiple Array MatriX (MAX) implementation, providing predictable timing, in-system programmability via IEEE 1149.1 JTAG, and 5.0-V in-system programmability (ISP). Within the broader taxonomy, the EPM9320LC84-20N belongs to: CPLD -> programmable logic device -> digital IC -> semiconductor. Key features include 60 user I/O pins, J-bend terminal form with a QCCJ (PLCC) package outline, commercial temperature grading (0C to +70C), and CMOS logic family operation. The device supports 5-V in-system programmability and is built on a 0.5um triple-layer-metal EEPROM process, allowing logic retention without external memory. The 84-pin PLCC package offers a square footprint with 60 usable I/Os plus dedicated programming, JTAG, and power pins. The MAX 9000 family uses a hierarchical interconnect structure that routes signals between Logic Array Blocks (LABs) and the Programmable Interconnect Array (PIA), delivering consistent timing regardless of design placement. This deterministic timing model is one of the primary reasons CPLDs continue to be selected over FPGAs for fixed-timing glue logic applications such as address decoding, interrupt control, and bus arbitration. Typical applications include address decoding and bus interface logic in legacy embedded systems, glue logic between microprocessors and peripherals, industrial control boards requiring deterministic timing, state-machine and sequencer implementation, replacement of discrete 74LS/74HC TTL glue, and 5-V tolerant I/O expansion for older MCU designs. The 5-V native I/O is a key reason engineers continue to specify MAX 9000 parts in mixed-voltage designs. When designing with this device, observe the 5-V VCC requirement and ensure all inputs do not exceed the absolute maximum ratings. Decouple VCC with 0.1uF and 10uF capacitors placed close to the PLCC pins, and use the JTAG port (TMS, TCK, TDI, TDO) for in-system programming. Note that the EPM9320LC84-20N is a mature, long-lived part still widely used for legacy industrial designs.
