M4A3-64/32-10JNI

Complex Programmable Logic Devices Overview

The M4A3-64/32-10JNI is a Complex Programmable Logic Device (CPLD) belonging to the ispMACH 4A family, manufactured by Lattice Semiconductor. It operates at a supply voltage of 3.3 V and features 64 macrocells with 32 user I/O options. The device supports a maximum operating frequency (f_CNT) of 167 MHz and has a maximum propagation delay (t_PD) of 10 ns. It utilizes E2CMOS technology for in-system programmability via JTAG (IEEE 1149.1). Key architectural features include SpeedLocking for guaranteed fixed timing, First-Time-Fit capability, and 100% pin-out retention.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'JNI' against official Lattice documentation to confirm package type and temperature range. Confirm availability status as legacy or end-of-life products may have limited supply chains. Ensure compatibility with existing design tools such asispDesign Expert.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 3.3 V operation with 64 macrocells. Compare t_PD of 10 ns against system timing requirements. Consider the 2:1 macrocell-to-I/O ratio which allows flexible routing through the output switch matrix. Verify if the 32 I/O count meets interface needs compared to the M4A3-64/64 variant.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4A CPLD family, which offers densities from 32 to 512 macrocells. The M4A3 series specifically denotes 3.3 V operation. The '-10' speed grade indicates a 10 ns maximum propagation delay. The family supports both commercial and industrial temperature ranges depending on the suffix.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-64 variants with different I/O counts or speed grades. For migration, consider the M4A5-64/32 for 5 V operation or higher density devices like M4A3-96 if more macrocells are required. Verify pinout compatibility when substituting.
