Product Details M4A5-64/32-10JNC is a programmable logic device from the Lattice ispMACH 4A family, designed for digital logic implementation, system control and interface management. The device integrates 64 macrocells and 32 user I/O connections in a 44-PLCC surface-mount package, providing programmable logic resources for electronic systems that require configurable digital functions.The device operates from a nominal 5V supply, with an internal supply range of 4.75V to 5.25V. Its 5V architecture makes it suitable for legacy and industrial electronic designs that use conventional 5V digital logic systems.With 64 macrocells and 32 I/O pins, M4A5-64/32-10JNC can implement a variety of combinational and sequential logic functions. The programmable architecture allows logic functions to be configured according to the requirements of the target system rather than relying exclusively on fixed-function logic devices.The maximum propagation delay is specified at 10ns for this speed grade. This characteristic allows the device to handle timing-sensitive digital control and interface functions where predictable logic propagation is required.M4A5-64/32-10JNC supports in-system programming, allowing the programmable logic device to be configured as part of the system development and manufacturing process. This capability can simplify design revisions and provide flexibility when digital logic requirements change during product development.The device supports JTAG-related programming and boundary-scan functions, providing additional options for system-level testing and device programming. These capabilities can be useful when the CPLD is integrated into larger digital systems containing multiple programmable and fixed-function devices.The 44-PLCC package uses a J-lead configuration and a 1.27mm terminal pitch. Its surface-mount construction provides a compact footprint for circuit boards while retaining the package style commonly used by legacy and industrial electronic equipment.Typical applications include digital logic control, interface bridging, bus control, address decoding, timing control and system management. The programmable architecture also makes the device suitable for replacing collections of discrete logic devices in certain existing designs.M4A5-64/32-10JNC can be useful in equipment where programmable logic is required but the system architecture is based on a 5V supply and established CPLD technology. The 64-macrocell architecture provides a practical level of programmable logic capacity for control and interface functions without requiring a larger FPGA.The specified commercial operating temperature range is 0°C to 70°C. System designers should evaluate the actual thermal environment, supply conditions, timing requirements and programming requirements before selecting the device for a new design.M4A5-64/32-10JNC is an obsolete Lattice programmable logic device, so availability and lifecycle status should be considered when sourcing for production or maintenance projects. For legacy equipment, repair programs and replacement applications, verifying the exact package, speed grade, temperature range and programming compatibility is important before purchasing.With 64 macrocells, 32 I/O, 10ns maximum propagation delay, 5V operation and a 44-PLCC package, M4A5-64/32-10JNC provides a programmable CPLD solution for digital control, interface logic and legacy electronic system applications.
