M4A5-32/32-10VI48

Complex Programmable Logic Devices Overview

The M4A5-32/32-10VI48 is a Complex Programmable Logic Device (CPLD) from the ispMACH 4A family, manufactured by Lattice Semiconductor. It operates at 5V and features 32 macrocells with a 1:1 macrocell-to-I/O ratio, providing 32 user I/O pins. The device is housed in a 48-pin TQFP package. Key electrical specifications include a maximum propagation delay of 10 ns and a maximum operating frequency of 125 MHz. It utilizes EEPROM technology for non-volatile storage and supports JTAG boundary scan testing.

• Automotive electronics applications within commercial temperature ranges

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as lead-free options are available for this family. Check for moisture sensitivity level handling requirements during storage and assembly. Ensure design files support the specific -10 speed grade and TQFP-48 package variant.

Complex Programmable Logic Devices Selection Notes

Select this model when 32 macrocells and 32 I/Os are sufficient for the design. The 10 ns speed grade suits applications needing 125 MHz operation. Choose the TQFP-48 package for surface-mount assembly constraints. Consider the 5V supply requirement versus 3.3V alternatives if system power differs. Verify thermal management needs for the TQFP package in enclosed environments.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A CPLD family, which offers flexible architecture and high routability. The M4A5 series specifically denotes 5V operation, distinguishing it from the 3.3V M4A3 series. The 32/32 designation indicates a 1:1 macrocell-to-I/O ratio, simplifying pinout retention compared to 2:1 ratio devices.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A5-32/32 variants with different speed grades or packages. Cross-family migration to newer Lattice CPLDs may require architectural adaptation. Verify pin compatibility and voltage levels when substituting with similar density devices from other manufacturers.
