EPM240T100A5N - 192-Macrocell MAX II CPLD, 100-TQFP | Intel / Altera
The Intel / Altera EPM240T100A5N is a 192-macrocell, 240-logic-element (LE) MAX II family non-volatile CPLD in a 100-pin TQFP package, operating from a 2.5V/3.3V supply and supporting user I/O at up to 201.1 MHz. The MAX II architecture delivers instant-on behavior via on-chip Flash configuration memory, eliminating the external configuration PROM required by legacy CPLDs and FPGAs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a sum-of-products architecture with macrocells and a global interconnect to implement glue logic, bus bridging, state machines, and interface translation. Within the broader taxonomy, the CPLD sits below the FPGA in silicon area but above discrete 74-series logic in integration, occupying a unique position for low-power, deterministic, latency-bounded designs. The MAX II family from Altera (now Intel) refined this category by integrating configuration Flash, reducing die size, and cutting static power versus the classic MAX 7000 series. Key specifications of the EPM240T100A5N include 192 macrocells (equivalent to 240 LEs), a 4.7 ns pin-to-pin logic delay, 80 user I/O pins, and in-system programmability via JTAG (IEEE 1149.1). The device supports hot-socketing, multi-voltage I/O banks, and operation across the commercial 0C to 85C range. Built on a 0.18 µm process, the part is optimized for low static power (~25 mW typical) and zero standby current during configuration. The MAX II family uses a Flash-backed LUT array feeding macrocells with product-term allocation, which simplifies timing closure compared to SRAM-based FPGAs. Designers benefit from deterministic propagation delays ideal for bus-bridge and protocol-state-machine roles where predictable latency matters more than maximum logic density. Typical applications include bus decoding and address latching in industrial PLCs, I/O expansion and signal conditioning in embedded systems, I2C/SPI/UART to parallel bus bridges, and power-sequencing logic in telecom backplane hardware. Its instant-on property makes it well suited as a power-rail sequencer or watchdog controller in conjunction with an FPGA host. When designing with this CPLD, plan for a JTAG header on the PCB to enable in-system programming and on-board debug. Quartus II (or the Intel Quartus Prime Lite edition) is the official toolchain; ensure I/O bank voltage selection matches connected peripherals to avoid contention at power-up. This page synthesizes distributor pricing, same-package MAX II cross-reference alternatives, and practical design notes not found in the manufacturer datasheet, providing a consolidated sourcing reference for engineers evaluating the EPM240T100A5N.
EPM240T100C3 - MAX II CPLD, 192 Macrocells, TQFP-100 | Intel
The Intel (formerly Altera) EPM240T100C3 is a MAX II family Complex Programmable Logic Device (CPLD) delivering 192 macrocells, 240 logic elements, and up to 80 user I/Os in a 100-pin TQFP (14x14 mm) package with a commercial 0C to 85C operating temperature grade. It operates from an internal core supply of 2.5 V or 3.3 V, supports in-system programmability through JTAG, and consumes a typical standby current of roughly 2 mA for low-power glue-logic applications. What is a CPLD? A Complex Programmable Logic Device is a non-volatile, flash- or EEPROM-backed programmable logic device that sits between simple PAL/GAL SPLDs and FPGAs in the programmable logic hierarchy. Compared to FPGAs, CPLDs offer instant-on configuration (no external boot PROM), deterministic timing with predictable pin-to-pin propagation delays, and excellent general-purpose I/O density at lower cost. They are widely used for I/O expansion, bus bridging, power-up sequencing, address decoding, and logic integration on cost-sensitive boards where FPGAs would be overkill. The EPM240T100C3 specifically belongs to the MAX II G (Green) family and features Instant-On capability, MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and a built-in User Flash Memory (UFM) block. Designers can also benefit from Altera/Intel Quartus II design software support, a generous JTAG-based ISP interface, and pin-compatible migration to higher-density MAX II devices like the EPM570 and EPM1270. Typical applications include I/O voltage translation and level shifting in mixed-voltage designs, bus multiplexing and address decoding for microprocessors and DSPs, configuration and control logic for FPGAs and SoCs, board-level glue logic replacing discrete 74-series gates, and digital signal conditioning or interface bridging between peripheral ICs. The wide I/O count and tolerant MultiVolt inputs make it well suited to industrial control, motor drive, and embedded computing motherboards. When designing with this device, ensure that I/O bank voltage rails match the connected peripherals; the UFM block is limited to approximately 8 Kbits of non-volatile storage and requires careful write/erase cycle management. Designers should also plan for the JTAG chain when multiple programmable devices share the same boundary-scan bus.
EPM240T100C3N - MAX II 240 LE CPLD, 100-TQFP | Intel/Altera
The Altera (now Intel) EPM240T100C3N is a member of the MAX II family of low-power, non-volatile CPLDs (Complex Programmable Logic Devices), providing 240 Logic Elements (LEs), 192 macrocells, and 80 user I/O pins in a 100-pin TQFP package. It features instant-on non-volatile Flash configuration memory, in-system programmability via JTAG, and support for multiple I/O standards including 1.5 V, 1.8 V, 2.5 V, 3.3 V LVCMOS/LVTTL. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy (PAL/GAL -> CPLD -> FPGA -> ASIC). Unlike SRAM-based FPGAs, MAX II CPLDs store their configuration in on-chip Flash, so they boot instantly without an external configuration PROM and retain their bitstream through power cycles. They are typically used for glue logic, bus bridging, power-up sequencing, and state-machine replacement where deterministic timing, low power, and instant-on behavior matter more than density. Key features include 8 Kbits of user Flash memory (UFM), 4.4 ns pin-to-pin logic delay (tPD), 200 MHz internal oscillator, and a MultiVolt I/O interface. The device operates from a single 3.3 V core supply with separate VCCIO banks for mixed-voltage interfacing, consumes only 35 mA typical quiescent current, and supports commercial temperature range (0 °C to +85 °C). The MAX II architecture combines a continuous interconnect fabric with Logic Array Blocks (LABs), each containing 10 Logic Elements. This non-volatile, instant-on approach eliminates the boot/configuration overhead of SRAM FPGAs, making the EPM240T100C3N a deterministic, low-power solution for high-volume glue-logic applications. Typical applications include I/O expansion and bus bridging, power-supply sequencing and supervisory logic, LED display driving, industrial control interfaces, and bootloader/reset management for FPGAs and microprocessors. The 80 user I/O pins provide flexible interfacing to parallel buses and digital sensor arrays. When designing with this device, allocate sufficient VCCIO decoupling (100 nF plus 10 µF bulk) at each bank, and verify JTAG chain integrity before relying on in-system programming. Designers migrating from older MAX 7000-series parts should review the MultiVolt core/I/O split and ensure 3.3 V core rails are present.

EPM240T100C4 - MAX II 192-MacroCell CPLD, 4.7ns TQFP-100 | Intel
The Intel (formerly Altera) EPM240T100C4 is a member of the MAX II family of instant-on, non-volatile CPLDs, delivering 192 macro cells, 240 logic elements, and 80 user I/O pins in a 100-pin TQFP package. Built on a 0.18 µm CMOS process with on-chip Flash configuration memory, it provides a maximum pin-to-pin propagation delay (tPD) of 4.7 ns and supports internal supply voltages of 2.5 V and 3.3 V with a commercial 0 °C to 85 °C operating range. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy. CPLDs are characterized by instant-on operation (no external boot PROM required), deterministic timing with predictable routing delays, low standby power, and pin-locked I/O architectures - making them ideal for glue logic, bus interfacing, state-machine control, and I/O expansion. The MAX II family specifically replaces legacy 3.3 V and 5 V CPLDs while cutting power by an order of magnitude. Key differentiating features of the EPM240T100C4 include 4.7 ns tPD for high-speed decode and interface logic, on-chip user Flash memory (typically 8 Kbits) for storing system parameters without an external EEPROM, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and JTAG (IEEE 1149.1) boundary-scan support for in-system programming and board-level test. Technically, the device integrates a Flash-backed Look-Up Table (LUT) architecture with a global interconnect matrix, replacing the classic EEPROM-and-macrocell fabric of older MAX families. This shift lowers static current to milliampere ranges, eliminates the boot delay, and lets the device behave like an 'instant-on' ASIC substitute - programming once and operating forever without intervention. Typical applications include I/O expansion and level translation between 3.3 V processors and 5 V peripherals, bus decoding for address/data steering in microcontroller systems, glue logic replacement for discrete 74-series gates, LED and 7-segment display drivers, and power-up sequencing controllers in embedded designs. When designing with this part, reserve one of the four JTAG pins (TCK, TMS, TDI, TDO) for ISP and boundary-scan test. The MultiVolt I/O banks require separate VCCIO rails per bank - verify the bank grouping in the datasheet pinout before assigning mixed-voltage signals. This page synthesizes real distributor pricing, drop-in same-package alternatives drawn from the MAX II product family, and practical design notes that go beyond the manufacturer datasheet summary.

It supports vertical migration with other MAX II density points such as the EPM570 and EPM1270 in the same 100-pin TQFP. The MAX II architecture uses a MultiCore interconnect that routes signals across Logic Array Blocks (LABs) with predictable timing, supporting hot-socketing, open-drain outputs, and bus-hold circuitry. Designers using Quartus II software can target the device through industry-standard VHDL or Verilog HDL with the IEEE Std. 1149.1 JTAG interface. Typical applications include I/O expansion and bus bridging, address decoding and glue logic in microprocessor/microcontroller systems, LED display driving, industrial control boards, consumer electronics interface management, and protocol translation. Engineers choose this part for instant-on, non-volatile logic that does not need a boot PROM. Designers should confirm that all VCCIO bank voltages match the connected logic levels and ensure the JTAG chain order is correct in multi-device boards. Decoupling capacitors (0.1 µF + 1 µF) close to each VCC pin are required for clean power-up. Use the Quartus II design software for synthesis, fitting, and programming.

EPM240T100C5 - MAX II CPLD, 192 Macrocells, 100-TQFP | Altera
The Altera (Intel) EPM240T100C5 is a MAX II family instant-on, non-volatile Complex Programmable Logic Device (CPLD) delivering 192 macrocells and up to 80 user I/O pins in a 100-pin TQFP package with speed grade 5. Built on a 0.18 µm, 6-layer-metal flash process, the device integrates 8 Kbits of non-volatile Flash memory for instant-on configuration with no external boot PROM, eliminating the configuration time of SRAM-based FPGAs and the boot delay of legacy serial PROMs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a macrocell-based architecture with continuous, distributed interconnect. In the system-level hierarchy, a CPLD sits below an FPGA (Field-Programmable Gate Array) in density, above small PAL/GAL devices, and below microcontroller units (MCUs) in flexibility. MAX II CPLDs target glue-logic, interface bridging, power-sequencing, and bus-management functions where deterministic timing and zero in-system configuration delay are mandatory. Key features include 192 logic elements, 4.7 ns pin-to-pin logic delay (tPD1), 201.1 MHz maximum internal operating frequency, support for 2.5 V and 3.3 V core supply operation, MultiVolt I/O supporting 1.5 V/1.8 V/2.5 V/3.3 V levels, JTAG-based IEEE 1149.1 boundary-scan testing and in-system programmability (ISP), and a global chip-wide DEV_OE output enable pin for board-level tri-state control. The device uses a non-volatile Flash-based architecture with 8 Kbits of embedded storage, four I/O banks for voltage-domain isolation, and on-chip pull-up resistors (User I/O pin 4 control) configurable in Quartus II. Each macrocell contains a programmable AND/OR array, a flip-flop, and feedback paths to the logic array, enabling compact state-machine and decoding-logic implementation. Typical applications include I/O expansion for microcontrollers and microprocessors, address decoding and chip-select generation in memory subsystems, bus-interface bridging (LVCMOS, LVTTL, PCI-compatible), power-supply sequencing in multi-rail systems, and configurable glue logic in industrial automation equipment. The instant-on behavior also suits FPGA configuration control, where the CPLD provides boot-up housekeeping before the main FPGA completes its configuration cycle. When designing with the EPM240T100C5, observe I/O bank voltage constraints: each of the four banks shares a common VCCIO that must match the signal level of devices connected to that bank. The 5.0-V tolerant I/O feature requires VCCIO at 3.3 V; do not apply 5 V to any I/O pin. Use Quartus II (legacy) or the Intel Quartus Prime Lite Edition for design entry, synthesis, and JTAG programming. This page consolidates distributor pricing, verified specifications, and curated drop-in alternatives not found in the manufacturer datasheet alone, helping engineers evaluate EPM240T100C5 for both new designs and legacy upgrades from MAX 7000S or classic PLDs.
EPM240T100C5N - 240-LE MAX II CPLD, 100-TQFP | Intel / Altera
The Intel / Altera EPM240T100C5N is a MAX II family instant-on non-volatile Complex Programmable Logic Device (CPLD) with 240 logic elements (192 equivalent macrocells), 8 Kbits of on-chip non-volatile flash storage, and a 4.7 ns pin-to-pin propagation delay (speed grade 5). It is fabricated on a 0.18 µm, 6-layer-metal flash process and is offered in a 100-pin TQFP (T100) package. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits between simple glue-logic gates and higher-density FPGAs. CPLDs typically combine a small AND/OR PLA-style fabric with a programmable interconnect matrix and a non-volatile configuration memory, providing instant-on behavior (no boot PROM required), deterministic timing, and excellent pin-to-pin delay predictability. Within the programmable logic taxonomy, the MAX II family occupies the low-density, low-power, instant-on tier — useful for I/O expansion, bus bridging, power-sequencing logic, and configuration control where FPGAs would be overkill. The EPM240T100C5N delivers 80 user I/O pins with MultiVolt I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V) on the same bank, enabling direct interfacing with mixed-voltage rails without level shifters. The device supports in-system programmability through IEEE 1149.1 (JTAG) and operates from a 2.5 V / 3.3 V core supply. Internal 8 Kbits of user flash allow storing non-volatile configuration data, custom IDs, or boot records without an external PROM. Architecturally, the MAX II CPLD uses a Logic Array Block (LAB) based fabric interconnected through a MultiTrack interconnect, with each LAB containing 10 Logic Elements. The device provides four I/O banks, JTAG boundary-scan, and a built-in oscillator. With a propagation delay around 4.7 ns and a maximum internal frequency near 201.1 MHz, the EPM240T100C5N comfortably addresses glue-logic, address decoding, LED/H-bridge control, and high-speed bus-interface applications. Typical applications include industrial control boards, telecom base-station glue logic, motor control pre-drivers, I/O expansion for microcontrollers, address decoding for memory subsystems, and portable / handheld consumer devices. Its instant-on behavior is especially valuable in power-sequencing and boot-loader roles. A key design consideration: the 100-TQFP package requires careful PCB layout because it lacks an exposed thermal pad, so all dissipation must flow through the peripheral leads — provide at least 4-layer stack-up with continuous ground plane. Programming is performed via the Quartus II / Quartus Prime design suite and a JTAG download cable (USB-Blaster or compatible).

The 'I' speed/temperature grade designation indicates the industrial -40C to +100C junction operating range with a 304 MHz internal performance figure, fabricated on a 0.18 um six-layer-metal flash process and supported by 2.5 V/3.3 V core and I/O supply rails. This is the MAX II instant-on, low-power variant in legacy Altera packaging with vertical migration to the EPM570 and EPM1270 in the same footprint. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple SPLDs/GLUE-logic PALs and high-density FPGAs in the programmable logic hierarchy. CPLD -> programmable logic -> PLD -> digital logic -> semiconductor. MAX II devices use a flash-based configuration cell instead of an external configuration ROM, giving them instant-on behavior (sub-millisecond wake-up), deterministic timing (no boot loader), and excellent suitability for I/O expansion, bus bridging, power-sequencing glue logic, and state-machine control. Compared to FPGAs, CPLDs such as the EPM240 offer lower static power, fixed propagation delay, and unlimited in-system reprogrammability via JTAG. Key features of the EPM240T100I3N include 192 macrocells distributed across 4 logic array blocks (LABs), 80 maximum user I/O, 4.6 ns pin-to-pin logic delay, a JTAG/IEEE 1149.1 compliant interface for in-system programmability (ISP), MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and an internal oscillator usable for simple clocking. The on-chip User Flash Memory block (8 Kbits) can store constants, serial numbers, or board revision IDs without an external EEPROM. Architecturally, the MAX II family uses a continuous, non-segmented flash memory cell per macrocell. Combined with a fine-grained logic element and a global LAB interconnect, this yields predictable 4.6 ns tPD1 propagation delay regardless of how many macrocells are used, simplifying static timing closure. The 100-pin TQFP package uses a standard JEDEC 14x14 mm body, 0.5 mm pitch, MSL-3 moisture sensitivity, and a -40C to +100C industrial junction temperature rating. Typical applications include I/O expansion and voltage-level translation in industrial controllers, glue-logic integration on FPGA-based motherboards, power-sequencer and watchdog controllers, JTAG-controlled bus bridges (I2C/SPI to parallel), LED-driver state machines, and motor-control peripheral interfaces. The instant-on, non-volatile nature of the EPM240 is especially valuable in safety-critical or deterministic-latency designs where FPGAs cannot meet cold-boot timing. Designers should note that the EPM240T100I3N is being phased out as part of the MAX II EOL roadmap; new designs should consider the MAX V family (5M80ZE64, 5M160ZE64) or MAX 10 (10M02) family for long-term availability.

The device achieves typical pin-to-pin propagation delays around 7 ns and supports in-system programmability through the Quartus II toolchain. From an architecture standpoint, the 240 LEs are organized into Logic Array Blocks (LABs), each containing 10 LEs, with interconnect driven by the MultiTrack interconnect fabric. The embedded UFM (8 Kbits) can store user data such as serial numbers, calibration constants, or boot parameters, eliminating a small EEPROM in many designs. Typical applications include I/O expansion and bus bridging between microcontrollers and peripherals, power-sequencer and supervisory logic, glue-logic replacement on industrial PCBs, LED-control drivers, and protocol-bridging glue for I2C/SPI/UART multiplexing. Its flash-backed instant-on behavior is also valued in motor-control and safety-critical industrial systems.

A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix. CPLDs sit below FPGAs in density and sit above discrete 74-series glue logic in flexibility; they are used for I/O expansion, bus bridging, power-up sequencing, and state-machine replacement where deterministic, low-latency, non-volatile behavior is required. The MAX II family adds 8 Kbits of user flash memory and removes the legacy EEPROM/CMOS-cell architecture of MAX 7000, lowering power and cost. Key features include 192 macro cells, 80 I/O pins, 8 Kbits of internal user flash memory, JTAG-based in-system programmability (IEEE 1149.1), 4-input look-up tables, and zero-power versus commercial junction temperature grades. The 100-pin TQFP package supports vertical migration to higher-density MAX II devices (EPM570, EPM1270, EPM2210) in the same footprint, preserving PCB design across multiple logic-density points. Architecturally, the EPM240T100C5N uses a non-volatile flash-based configuration cell so it powers up in a defined state within microseconds - a major advantage over SRAM FPGAs that require an external boot PROM and configuration time. MultiVolt I/O supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces from a single 3.3 V core supply, simplifying mixed-voltage board designs. Typical applications include I/O expansion and voltage translation in industrial control boards, glue logic replacement in telecom/networking line cards, bus-interface bridging (PCI to local bus, address decoding), power-up/power-down sequencing in ATCA/ATX platforms, and LED-control or motor-control state machines in consumer and industrial equipment. When designing with this device, use the Intel Quartus Prime design suite (free Web Edition supports MAX II) for synthesis, place-and-route, programming-file generation, and JTAG programming via the Altera USB-Blaster or compatible cable. Decouple all VCCINT/VCCIO pins with 0.1 µF capacitors placed within 100 mils of the package pins.

The Intel (formerly Altera) EPM240ZM100C6N is a 192-macrocell MAX II zero-power CPLD housed in a 100-pin Micro FineLine BGA (MBGA) package, fabricated on a 0.18-µm 6-layer-metal flash process. It provides 240 logic elements (LEs), 80 user I/Os, a 7.5 ns pin-to-pin propagation delay, and an internal clock network supporting up to 184.1 MHz. The instant-on, non-volatile flash-based architecture delivers the deterministic power-on behavior of an ASIC with the design flexibility of a programmable logic device, eliminating the external configuration PROM required by SRAM-based FPGAs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with a central interconnect matrix. CPLDs sit in the programmable logic hierarchy alongside FPGAs, but are distinguished by their non-volatile (instant-on) configuration, deterministic timing, and suitability for glue-logic, interface bridging, and control-plane applications. MAX II belongs to the broader programmable logic device (PLD) family, branching from simple PLDs (SPLDs) through CPLDs and FPGAs into system-on-chip (SoC) FPGAs. Key features include MultiVolt core support, allowing the device to interface with 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic without level shifters; an integrated User Flash Memory (UFM) block of up to 8 Kbits for non-volatile data storage; four global clocks with two clocks per logic array block; and standby current as low as 25 µA. The Z-suffix device provides the lowest-power variant of the MAX II family, well suited to battery-backed and energy-conscious designs. Typical applications include bus interface bridging (e.g., 8-bit MCU to 32-bit bus), power-up sequencing logic, I/O expansion for low-pin-count microcontrollers, configuration control for FPGAs and memories, and digital signal conditioning. Its compact 6 × 6 mm footprint makes it attractive for space-constrained PCBs in industrial control, consumer electronics, and portable instrumentation. Designers should note that the MBGA package requires careful PCB layout - micro-via fan-outs and controlled-impedance routing are recommended. The device operates over a 1.8 V core supply with MultiVolt I/O, and supports JTAG-based in-system programmability (ISP) for field updates.

EPM240ZM100C7N - MAX II Z CPLD 192MC 7.5ns 100-MBGA | Altera/Intel
The Altera (Intel) EPM240ZM100C7N is a low-power, non-volatile CPLD from the MAX II Z family with 240 logic elements (192 macrocells), 7.5 ns pin-to-pin logic delay, and 80 user I/Os housed in a 100-ball Micro FineLine BGA (MBGA) package. It is fabricated on a 0.18-µm 6-layer-metal flash process that integrates configuration storage on-die, eliminating the need for an external boot PROM. The device operates from a single 1.8 V core supply and supports MultiVolt I/O banks at 1.5 V, 1.8 V, 2.5 V, 3.3 V, and is pin-compatible with the corresponding MAX II G device in the same 100-pin MBGA. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that provides instant-on operation, deterministic timing, and flexible glue-logic integration between microcontrollers, ASICs, and standard bus interfaces. CPLDs sit below FPGAs in the programmable logic hierarchy: they typically offer lower density but faster, fully deterministic propagation delays, making them ideal for address decoding, bus interfacing, power-up sequencing, and peripheral control rather than high-throughput data-path or DSP workloads. The MAX II family is the lowest-power instant-on CPLD family in the Altera/Intel portfolio. Key features include 8 Kbits of on-chip user flash memory (UFM) for storing constants, serial numbers, or calibration data; a JTAG (IEEE 1149.1) interface for in-system programming and boundary-scan test; support for I/O standards including LVCMOS, LVTTL, PCI, and differential LVDS; and a typical standby current under 2 mA at 1.8 V core. The Z sub-family variant is engineered specifically for ultra-low static power dissipation, making it well suited to battery-powered and energy-harvesting designs where the device must idle for long intervals without draining the source. Architecturally, the EPM240ZM100C7N is built around the Logic Array Block (LAB) interconnect fabric, with each LAB containing 10 logic elements and each LE implementing a 4-input look-up table, a programmable register, and a carry chain. The MultiVolt I/O architecture lets each bank be powered independently from the core, allowing direct interfacing to legacy 5 V-tolerant buses through external series resistors or level shifters. The device retains all configuration in on-chip flash, so power-up time is governed only by the I/O ramp-up sequence rather than by a PROM load cycle. Typical applications include I/O expansion and address decoding for microcontrollers and microprocessors, power-up sequencing in multi-rail systems, glue logic in industrial control and factory automation boards, low-power portable and battery-backed instrumentation, LED display multiplexing, and consumer-electronics control boards. The 100-ball MBGA package has a footprint of approximately 6 x 6 mm, making it one of the smallest footprints available in the MAX II family. When designing with the EPM240ZM100C7N, plan the MultiVolt bank assignments carefully because each I/O bank shares a VCCIO rail and mixing 1.5 V and 3.3 V signals requires at least two banks. Use Quartus II Web Edition (or the latest supported Intel Quartus Prime release) for design entry, fitting, and in-system programming via the JTAG port.

The 'Z' speed grade and 'I8' industrial temperature suffix confirm operation from -40C to +100C junction with sub-7.5 ns timing, while the device is fabricated on a 0.18 µm CMOS process and operates from a 1.8 V core supply. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy: CPLD -> programmable logic -> logic IC -> semiconductor. Unlike SRAM-based FPGAs, MAX II CPLDs use on-chip Flash configuration memory, providing instant-on behavior in <1 ms and deterministic, glitch-free I/O at power-up - which is critical for bus arbitration, glue logic, and power-supply sequencing. Key features include 192 macro cells organized into 4 logic array blocks (LABs) with 240 logic elements per LAB family, 80 maximum user I/Os, 7.5 ns tPD (pin-to-pin delay), 118.3 MHz internal performance, 1.8 V VCCINT core supply, 1.5 V to 3.3 V VCCIO multi-voltage I/O support, and built-in IEEE Std. 1149.1 JTAG boundary-scan. The MAX II architecture uses a MultiVolt core plus per-bank I/O voltage translators, allowing 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces from a single 1.8 V rail. Architecturally, the EPM240ZM100I8N routes signals through a continuous interconnect with fast propagation delays, while on-chip UFM (User Flash Memory, 8 Kbits) provides non-volatile parameter storage without an external EEPROM. The combination of low standby current (<2 mA typical), instant-on, and JTAG-driven in-system programmability (ISP) suits power-sensitive and field-upgradable designs. Typical applications include bus bridging and voltage-level translation between 3.3 V MCUs and 1.8 V peripherals, power-supply sequencing and supervisory glue logic, LED display driving, I/O expansion for microcontrollers without enough pins, and boot-loader/state-machine controllers in industrial, automotive, and consumer systems. When designing with the EPM240ZM100I8N, ensure the 100-MBGA PCB layout accommodates 0.5 mm-pitch BGA escape routing (microvia or HDI recommended) and that VCCINT and VCCIO decoupling follows the MAX II handbook recommendation of 0.1 µF + 1 µF ceramic capacitors within 3 mm of each supply pin.

The Intel / Altera EPM240ZM68C6N is a non-volatile, flash-based Complex Programmable Logic Device (CPLD) from the MAX II family, delivering 192 macrocells with a 7.5 ns pin-to-pin propagation delay in a 68-ball Micro FBGA package. It is fabricated on a 0.18 µm process, operates from a 1.8 V core supply, and supports user I/O at multiple voltage standards through banked VCCIO rails, providing a flexible glue-logic and bus-bridging platform for cost-sensitive designs. A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on digital IC that combines multiple PAL-like logic blocks on a single die, with a programmable interconnect matrix routing signals between them. Architecturally, a CPLD sits between small glue-logic gate arrays (a few dozen gates) and full FPGAs (tens of thousands of LUTs with soft cores and SERDES). The MAX II family — to which the EPM240Z belongs — is Altera's (now Intel) zero-power CPLD line: it replaces the classic EEPROM or antifuse cell with on-chip flash configuration memory, eliminating the external boot PROM that legacy MAX devices needed and giving instant-on behavior similar to an FPGA with bitstream pre-loaded into flash. Key features of the EPM240ZM68C6N include 192 macrocells (~240 logic elements in legacy Altera nomenclature, hence the '240' prefix), 184.1 MHz internal performance, 80 user I/O pins broken into I/O banks, multi-voltage support (1.5 V, 1.8 V, 2.5 V, 3.3 V I/O standards) via banked VCCIO, in-system programmability through JTAG, and low standby current characteristic of the MAX II Z-series. The Micro FBGA-68 package is a chip-scale BGA suited to high-density PCB designs where board area is constrained. The architecture combines Look-Up Table (LUT) based logic array blocks (LABs) with a global interconnect that fans out across the die. Each macrocell contains a programmable flip-flop, product-term logic, and a configurable output buffer. Compared to discrete 74-series glue logic, the EPM240Z replaces dozens of packages with a single device while adding reconfigurability for late-stage design changes, BOM consolidation, and obsolescence management. Typical applications include bus-bridging between processors operating at different voltages, glue-logic replacement for 74HC/74LVC series gates, address decoding in microcontroller systems, LED driving and PWM generation, I/O expansion for FPGAs or microcontrollers with insufficient pins, and board-level power sequencing. Designers also use the device in industrial control, motor drive signal conditioning, and portable instrumentation where low standby current matters. When designing with the EPM240ZM68C6N, mind that the 68-ball Micro FBGA requires X-ray or careful hot-air rework for prototyping and that JTAG chain sharing must be planned if the board already contains an FPGA or another programmable device. The Intel Quartus II (or Quartus Prime Lite) toolchain supports this part with full synthesis, place-and-route, and timing analysis.

The non-volatile flash configuration bit cells eliminate external boot PROMs and provide design security, while the global clock network supports up to four dedicated clock pins with glitch-free MUX switching. Typical applications include I/O expansion and bus bridging in industrial control, power-up sequencing for FPGAs and processors, address decoding in networking equipment, peripheral glue logic in embedded systems, and LED display multiplexing. Its zero standby current and small Micro BGA footprint also suit portable and handheld designs. When designing with the EPM240ZM68C7N, note that the MBGA package requires careful PCB layout with microvia or via-in-pad technology, and that I/O banks must share a single VCCIO voltage. JTAG pins should be reserved for programming access, and unused pins must be left floating per the device handbook recommendation.

The MAX architecture implements each macrocell with a programmable AND/OR array plus a configurable flip-flop, supporting combinatorial or registered outputs. The LAB interconnect uses a fast uniform delay matrix so any pin-to-pin path can be predicted by adding the routing delay to the macrocell delay, simplifying static timing analysis for critical control paths. Typical applications include JTAG-based board-level glue logic, address decoding and bus-interface bridges for 8/16-bit microcontrollers, I/O expansion for low-density FPGAs, and industrial control state machines. Its 34 I/Os comfortably support 32-bit datapath multiplexing plus control signals. When designing, observe 3.3 V I/O compatibility — the EPM3032A inputs are not 5 V tolerant, so external level translation is required when interfacing with 5 V logic. Use the Altera MAX+PLUS II or Quartus II design tools for compilation, fitting, and ISP programming.

Typical applications include bus-interface bridging, address decoding, glue logic for ASIC/FPGA designs, power-up sequencing controllers, and legacy 5V system integration. The PLCC-44 footprint also makes it attractive for industrial control boards and retrofits where through-hole or socketed programmable logic is preferred over fine-pitch BGAs. Compared with microcontrollers, the EPM3032A executes combinational decisions in a single 4.5 ns propagation delay, eliminating firmware overhead and the latency of interrupt-driven code. When designing with this part, allocate JTAG pins (TDI, TDO, TMS, TCK) for in-system programming and boundary-scan test. Reserve the dedicated input pin GCLK1 for high-fanout global clock distribution, and use the GCLRn pin for asynchronous global clear. The PLCC socket allows easy firmware updates during prototyping; in production, choose the -10N speed grade (commercial 0C to +70C) or migrate to the -10I industrial grade for -40C to +85C operation.

EPM3032ALC44-10 - MAX 3000A CPLD, 32 Macrocells, 10ns, 44-PLCC | Intel / Altera
The Intel / Altera EPM3032ALC44-10 is a member of the MAX 3000A family of high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs) built on the Altera MAX architecture. The device provides 32 macrocells, 2 logic array blocks (LABs), 34 user I/O pins, a 10 ns pin-to-pin propagation delay, and is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC, J-Lead) package. The EPM3032ALC44-10 operates from a 3.3 V supply and offers in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and FPGAs in the programmable logic hierarchy: PAL/GAL -> CPLD -> FPGA. CPLDs use EEPROM or flash configuration memory, providing instant-on behavior at power-up with no external boot PROM, and offer deterministic timing with predictable pin-to-pin delays - making them ideal for glue-logic, interface bridging, and control-plane functions rather than high-density data-path processing. Key features of the EPM3032ALC44-10 include 600 usable gates, an internal counter frequency of up to 227.3 MHz, 3.3 V ISP via JTAG compliant with IEEE Std. 1532, multi-vendor concurrent programming support, and built-in JTAG boundary-scan test. The device operates across the commercial 0C to +70C temperature range and is offered in a surface-mount 44-PLCC J-lead package for socketed or hand-soldered prototype applications. The MAX 3000A architecture implements a classic AND-OR plane feeding a programmable macrocell array, where each macrocell contains a flip-flop with configurable clock/clear options. Logic is implemented through a programmable interconnect array (PIA) that provides deterministic, fixed-delay routing - this is why CPLD timing is specified as a simple pin-to-pin number (10 ns here) rather than the statistical Fmax used for FPGAs. Typical applications include bus-interface bridging (e.g., 8-bit MCU to 16-bit peripheral), address decoding, power-up sequencing logic, configurable peripheral glue logic in industrial controllers, and JTAG-driven board-level test infrastructure. The 44-PLCC package is also socket-friendly, which simplifies laboratory prototyping and field replacement. Design consideration: a single 3.3 V rail is sufficient - no separate core/IO supply is required. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of each VCC pin, and provide a JTAG header for in-system programming. Compared with the EPM3032ATC44-10 variant, this -10 speed grade offers the slowest timing margin, which is acceptable for control-plane logic running below 50 MHz.

EPM3032ALC44-10N - 32 Macrocell CPLD, 10ns, 44-PLCC | Altera
The Altera EPM3032ALC44-10N is a 32-macrocell, 600-gate CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package with a 10 ns pin-to-pin propagation delay. It operates from a 3.3 V core supply and supports in-system programmability (ISP) via the built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface, while the ISP circuitry itself complies with the IEEE Std. 1532 concurrent-programming specification. A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PAL/GAL-style macrocell arrays on a single chip with a programmable interconnect matrix. CPLDs sit between small PAL/GAL SPLDs and larger FPGAs in the programmable logic hierarchy: low-power, deterministic timing, and zero-configuration boot make them ideal for glue logic, bus interfacing, and control-plane state machines. The MAX architecture used in the EPM3032A family places logic into Logic Array Blocks (LABs), each containing multiple macrocells with configurable product-term logic and flip-flops. The EPM3032ALC44-10N integrates 2 Logic Array Blocks hosting 32 macrocells total, exposes 34 user I/O pins, and delivers an internal fMAX around 103.1 MHz at the 10 ns speed grade. MultiVolt I/O allows the I/O bank to interface with 1.8 V, 2.5 V, 3.3 V and 5.0 V mixed-voltage systems without external level shifters, which simplifies board design when bridging legacy peripherals to modern ASICs. Built-in boundary-scan (BST) circuitry supports IEEE 1149.1 manufacturing test and on-board JTAG programming. From an architectural standpoint, the MAX 3000A device uses an EEPROM-based configuration cell that retains the bitstream without external boot memory, so the device is functional within microseconds of power-up. The non-volatile cell also enables 100% CMOS compatibility with low standby current and supports 100 erase/program cycles for in-field updates via JTAG. Typical applications include industrial control glue logic, address decoding and bus interfacing on legacy PCI/ISA backplanes, power-up reset sequencing, state-machine control for motor drives, LED and seven-segment display multiplexing, and portable / battery-powered devices that benefit from instant-on, low standby power logic integration. Designers should consider the 3.3 V VCCINT requirement and ensure bulk decoupling (typically 0.1 uF + 10 uF) is placed adjacent to the PLCC power pins; unused I/O pins should be left floating or tied to VCCIO through a resistor to avoid floating-input oscillation.

EPM3032ALC44-4 - 32-Macrocell 4.5ns CPLD | Altera MAX 3000A
The Altera EPM3032ALC44-4 is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, featuring 32 macrocells, 2 Logic Array Blocks (LABs), 34 user I/O pins, and pin-to-pin logic delays as fast as 4.5 ns. It is housed in a 44-pin PLCC (Plastic Leaded Chip Carrier, J-Lead) package and operates from a 3.3 V core supply with MultiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V logic levels for mixed-voltage system integration. What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy. CPLDs (Complex Programmable Logic Device -> Programmable Logic Device -> Logic IC -> Integrated Circuit -> Semiconductor) provide fast, deterministic propagation delays, instant-on operation from on-chip EEPROM, and predictable timing that makes them ideal for glue logic, bus decoding, and control-plane functions. The MAX 3000A family is positioned at the entry-level of Altera's CPLD portfolio, providing 600 to 10,000 usable gates with 3.3-V in-system programmability (ISP). Key features of the EPM3032ALC44-4 include counter frequencies up to 227.3 MHz, IEEE Std. 1149.1 JTAG interface for boundary-scan testing, and IEEE Std. 1532-compliant ISP that allows concurrent in-system programming across multiple PLD vendors. The device provides a low-power, EEPROM-based architecture that retains configuration without an external boot PROM, instant-on at power-up, and is fabricated on advanced CMOS technology. Commercial temperature grading supports 0°C to +70°C ambient operation. Architecturally, the MAX 3000A family employs a classic MAX-style interconnect structure where each LAB combines 16 macrocells with a global interconnect. Each macrocell contains a programmable AND/OR array, a configurable flip-flop, and product-term steering logic. The 4.5 ns pin-to-pin delay enables high-speed glue-logic replacement at clock rates that would otherwise require discrete 74-series logic, while the 227.3 MHz counter frequency supports high-performance state machines and FIFO address pointers. Typical applications include bus decoding and address mapping in microprocessor and DSP systems, glue-logic replacement for legacy 74LS/74HC designs, power-up sequencing controllers, state-machine implementation, I/O expansion for microcontrollers, peripheral interfacing, and JTAG-driven production programming. The MultiVolt I/O makes it well suited as a voltage-level translator between 5.0 V and 3.3 V logic domains in mixed-voltage embedded designs. When designing with the EPM3032ALC44-4, ensure the I/O bank supply (VCCIO) matches the driven logic level to avoid contention. Use the Quartus II (or legacy MAX+PLUS II) toolchain for design entry, fitting, and programming file generation. Place decoupling capacitors (0.1 µF) close to each VCC and VCCIO pin and reserve a JTAG header for ISP.
