5M40ZE64C5N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocells with a centralized interconnect fabric. Positioned in the programmable logic hierarchy below FPGAs but above simple SPLDs, MAX V CPLDs offer instant-on behavior (sub-millisecond configuration), deterministic timing, and high-drive I/Os that drive 5.0 V backplanes. They sit within the broader taxonomy of programmable logic devices (PLDs) > non-volatile logic > glue-logic replacement ICs.
Key features include 1.8 V core operation with multi-voltage I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V LVCMOS/LVTTL), in-system programmability via JTAG (IEEE 1149.1), and on-chip voltage regulation requiring only a single 3.3 V external supply. The Flash-based configuration eliminates external boot memory and supports 100% factory-tested fault coverage.
Architecturally, the 5M40ZE64C5N uses Altera's classic Lab/Local FastTrack interconnect routing with 4-input look-up tables per LE, product-term allocation across macrocells, and a user Flash memory block (UFM) that provides non-volatile user storage. The 7.5 ns tPD1 timing makes it ideal for high-speed address decoding, bus interface logic, and asynchronous state-machine replacement in mixed-voltage systems.
Typical applications include address decoding and bus interface bridging in industrial controllers, I/O expansion and level translation in telecom line cards, glue-logic consolidation in medical instruments, and power-sequencer or reset-distribution networks in networking switches. The wide I/O voltage range makes it a flexible companion to legacy 5 V MCUs that still require 3.3 V or 1.8 V peripherals.
When designing with this device, plan the I/O bank assignments carefully because each bank has a fixed VCCIO reference. Use the Quartus Prime design suite for synthesis, fitting, and in-system programming; the JTAG chain can also be used for boundary-scan testing on production boards.

Typical Applications
5M40ZE64C5N is suitable for 6 applications: Address Decoding and Bus Interface Bridging, I/O Expansion and Level Translation, Industrial Glue Logic Consolidation, Power Sequencing and Reset Distribution, Legacy 5 V System Modernization, State Machine and Protocol Conversion.
Address Decoding and Bus Interface Bridging
The 5M40ZE64C5N fits address decoding and bus-interface bridging because its 7.5 ns pin-to-pin propagation delay (tPD1) and 118.3 MHz internal frequency comfortably decode a 50-100 MHz processor or memory bus without inserted wait states. Its 32 macrocells provide ample product-term capacity for chip-select and byte-enable generation across multiple memory banks. Placed between a CPU and its memory/ASIC peripherals, the CPLD replaces discrete 74-series glue logic with a single Flash-programmable device, reducing board area and BOM cost. The multi-voltage I/O banks (1.5/1.8/2.5/3.3 V) allow direct connection to processors and peripherals running on different supply rails, eliminating external level translators and improving signal integrity on the decoded strobes.
Recommended
I/O Expansion and Level Translation
The 5M40ZE64C5N serves as an I/O expansion and level-translation bridge between mixed-voltage ASICs and processors. Each of its I/O banks supports an independent VCCIO voltage (1.5/1.8/2.5/3.3 V), so a 1.8 V processor GPIO can directly drive a 3.3 V peripheral or vice versa through the CPLD's bidirectional I/O cells. With 54 user I/Os available in the 64-pin EQFP package, it can expand a small microcontroller into a multi-bank mixed-signal system. The instant-on Flash configuration ensures the level-translation paths are active within microseconds of power-up, critical for systems where the MCU is held in reset until the I/O voltages are stable.
Recommended
Industrial Glue Logic Consolidation
The 5M40ZE64C5N consolidates 5 to 15 discrete 74-series logic gates into a single programmable device in industrial PLC and motor-drive controllers. Its 32 macrocells replace latches, flip-flops, monostable multivibrators, and combinational decoders with a Flash-programmable equivalent that fits on a 64-pin EQFP land pattern. The non-volatile configuration eliminates PROM failures common in high-vibration factory-floor environments, and the instant-on behavior lets I/O signals settle before the host MCU boots. Engineers can re-spin logic revisions by re-programming via JTAG on the production line, avoiding board respins and reducing time-to-market for industrial customers.
Recommended
Power Sequencing and Reset Distribution
The 5M40ZE64C5N is ideal for power-sequencing and reset-distribution networks in networking switches and telecom line cards. Its deterministic 7.5 ns timing lets designers build daisy-chained PG (power-good) and RESET signal chains that bring ASICs, FPGAs, and PHYs up in the correct order. Each of the 54 user I/Os can be configured with a weak pull-up, bus-keeper, or open-drain mode, matching the diverse reset-network requirements of multi-rail systems. The on-chip User Flash Memory (UFM) can store board-specific calibration data or MAC addresses alongside the configuration image, eliminating an external EEPROM from the BOM and reducing bill-of-material cost.
Recommended
Legacy 5 V System Modernization
The 5M40ZE64C5N bridges new low-voltage processors to legacy 5 V peripherals in medical instruments and factory automation systems. Its LVCMOS/LVTTL I/O banks interface directly with 3.3 V or 1.8 V modern MCUs while the programmable logic provides the level-shifting behavior to drive 5 V-tolerant signal chains. The 32 macrocells can implement Schmitt-trigger input conditioning and debounce logic for noisy mechanical switches and relays common in industrial control panels. Replacing legacy 74LS/74HC TTL gates with a single CPLD reduces standby current and board area while keeping the legacy 5 V peripheral interface fully functional.
Recommended
State Machine and Protocol Conversion
The 5M40ZE64C5N implements compact finite state machines and lightweight protocol converters such as I2C-to-parallel, SPI-to-GPIO, or UART-to-keyscan. Each of the 40 Logic Elements contains a 4-input LUT and a programmable register, well-suited for Moore or Mealy state machines with 8 to 16 states. The 7.5 ns tPD1 enables bit-rate matching at standard SPI speeds up to 50 MHz. Combined with the on-chip JTAG, designers can add production-testable logic that simplifies board bring-up and boundary-scan coverage without external test fixtures, a useful feature for low-volume medical and industrial products.

Key Differentiators
- Non-volatile Flash configuration eliminates external boot PROM (vs 5M160ZE64C5N)
- Lowest 5M40ZE64 density in the 64-EQFP package (vs 5M160ZE64C5N)
- Independent VCCIO banks for mixed-voltage designs (vs XC9536XL-64VQG64 (Xilinx XC9500XL))
Design Notes
The 5M40ZE64C5N requires a single 3.3 V external supply; the on-chip voltage regulator generates the 1.8 V core voltage internally. Decouple VCCINT and each VCCIO bank with 0.1 uF ceramic capacitors placed within 5 mm of the supply pins, and add a bulk 10 uF tantalum or ceramic capacitor at the regulator input. Each I/O bank has its own VCCIO pin; do not tie VCCIO banks together unless the design specifies the same voltage for the entire bank group.
Use a four-layer PCB with a dedicated ground plane and a power plane cut to avoid crossing noisy signal traces above split power regions. Route JTAG signals (TCK, TMS, TDI, TDO) away from high-speed switching signals; keep TCK trace length under 75 mm to meet IEEE 1149.1 timing. Connect the exposed thermal pad on the 64-pin EQFP package to the ground plane with multiple thermal vias (0.3 mm drill, 0.6 mm pad, 1.0 mm pitch) to improve heat dissipation during high-I/O-toggle operation.
Do not exceed the maximum I/O per bank current limit of approximately 25 mA per pin or 100 mA per bank - distribute high-current loads across multiple banks. Leave JTAG pins unused but pulled to a defined state (TDI/TMS pulled up, TCK pulled down through 10 kohm) if JTAG is not used to prevent spurious configuration events. The User Flash Memory (UFM) shares configuration logic; do not access the UFM during in-system programming without first pausing the JTAG state machine.
