EPM240ZM68C7N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the digital hierarchy between simple PAL/GAL arrays and larger FPGAs. It provides deterministic, single-cycle combinational and sequential logic with predictable timing, making it ideal for glue logic, bus interfacing, and power-up control functions. Within the broader taxonomy, the MAX II family belongs to the non-volatile CPLD category of programmable logic devices (CPLD -> PLD -> programmable logic -> digital IC -> semiconductor). The Z-series variant used here emphasizes zero-power standby consumption, suiting battery-aware systems.
Key differentiating features of the EPM240ZM68C7N include its instant-on architecture (configuration time below 0.5 ms thanks to internal flash), zero standby current in shutdown mode, and MultiVolt I/O supporting mixed-voltage buses. The device provides 240 logic elements (192 equivalent macrocells), 8 Kbits of user flash, up to 123.5 MHz internal performance, and JTAG-based in-system programmability through IEEE 1149.1 boundary scan.
The architecture uses a uniform logic element array interconnected by a continuous FastTrack routing fabric, with each LE containing a 4-input look-up table, a programmable register, and a carry chain for arithmetic operations. 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.

Notes de conception
The 68-ball Micro BGA package requires microvia or via-in-pad PCB technology for reliable assembly. Use ENIG (Electroless Nickel Immersion Gold) surface finish to ensure solder joint reliability. Estimated ball pitch: 0.5 mm; verify exact ball pitch in the MAX II Device Handbook pin table before laying out footprints.
The MAX II family integrates an internal 1.8 V regulator, so only VCCIO bank supplies and the JTAG supply need to be provided externally. Decoupling: place 0.1 µF ceramic capacitors close to every VCCIO pin and at least one bulk 10 µF tantalum or polymer cap per supply rail. Zero standby current is maintained only when all I/O are static and the JTAG controller is idle.
Common pitfalls include: (1) sharing VCCIO between banks that need different voltages; (2) leaving JTAG pins unconnected, blocking in-system programming; (3) forgetting to set unused pins as inputs with weak pull-up per Quartus II default; (4) underestimating the multi-bank supply routing on the BGA escape. Always run Quartus II fitter reports and TimeQuest timing analysis before tape-out.
For high-speed interfaces above 100 MHz, use controlled-impedance PCB traces (50 ohm single-ended, 100 ohm differential) and keep clock traces as short as possible. Place series termination resistors near the CPLD output pin when driving long transmission lines. The four global clock pins (CLK0-CLK3) have dedicated routing that minimizes skew - prefer them for all clock inputs.
