M4A3-32/32-10JNI

Complex Programmable Logic Devices Overview

The M4A3-32/32-10JNI is a member of the ispMACH 4A family, a high-performance E²CMOS Complex Programmable Logic Device (CPLD). It features 32 macrocells and supports 3.3-V operation with JTAG in-system programming. The device offers a propagation delay (tPD) of 5.0 ns and a counter frequency (fCNT) of 182 MHz. It utilizes a flexible architecture with central, input, and output switch matrices to ensure 100% routability and pin-out retention. The -10 speed grade indicates commercial temperature range support.

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix 'JNI' against the manufacturer's official package selection guide to confirm the specific plastic leaded chip carrier (PLCC) or quad flat pack (QFP) variant and industrial/commercial temperature rating. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring guaranteed fixed timing via SpeedLocking technology with up to 20 product terms per output. The 32-macrocell density is suitable for moderate complexity logic functions. Verify that the 3.3-V supply voltage aligns with the system design, noting its compatibility with 5-V inputs.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which provides E²CMOS technology for non-volatile configuration. The family ranges from 32 to 512 macrocells, offering various package options including PLCC, PQFP, TQFP, BGA, fpBGA, and caBGA. The M4A3 series specifically denotes 3.3-V operation.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-32 variants with different speed grades (e.g., -5, -6) or package suffixes. Cross-family migration to ispMACH 4S or ispMACH 5 requires architectural re-evaluation due to differences in macrocell structure and I/O capabilities.
