M4A5-128/64-10YC

Complex Programmable Logic Devices Overview

The M4A5-128/64-10YC is a 5-V ispMACH 4A CPLD featuring 128 macrocells and 64 user I/Os. It operates within a 4.75 V to 3.6 V supply range, delivering a maximum propagation delay of 10 ns and a maximum count frequency of 167 MHz. The device utilizes E2CMOS technology for non-volatile configuration and supports JTAG in-system programming. It is housed in a 100-pin TQFP package with an operating temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• High-performance 5-V E2CMOS architecture with 128 macrocells and 64 I/Os
• SpeedLocking feature guarantees fixed timing up to 10 ns tPD and 167 MHz fCNT
• JTAG (IEEE 1149.1) compliant for boundary scan testing and in-system programming
• Flexible switch matrices ensure 100% routability and pin-out retention

Complex Programmable Logic Devices Applications

• PCI-compliant interface logic
• Mixed voltage system integration
• Industrial control systems
• Communication board logic

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the component meets RoHS requirements if lead-free packaging is specified for the project. Confirm that the 5-V operation aligns with the target system's power supply specifications.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring guaranteed fixed timing without performance degradation from complex logic. The 5-V operation is suitable for legacy interfaces or mixed-voltage environments where 3.3-V devices cannot accept 5-V inputs directly. Consider the 100-pin TQFP package constraints for PCB layout.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4A family, which offers densities from 32 to 512 macrocells. The M4A5 series specifically denotes 5-V operation, contrasting with the M4A3 series for 3.3-V applications. The '128/64' designation indicates the macrocell and I/O count, while '10' refers to the 10 ns speed grade.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A5-128 variants with different speed grades (e.g., -5, -55, -6, -65, -7, -12) or package options. Verify that any substitute maintains the 5-V supply requirement and the 100-pin TQFP footprint if pin compatibility is critical.
