M4A3-32/32-12JNI

Complex Programmable Logic Devices Overview

The M4A3-32/32-12JNI is a member of the Lattice ispMACH 4A family, a high-performance E2CMOS Complex Programmable Logic Device (CPLD). It operates at 3.3 V and features 32 macrocells with a 1:1 macrocell-to-I/O cell ratio, providing 32 user I/O options. The device utilizes an architecture with central, input, and output switch matrices to ensure 100% routability and pin-out retention. Key electrical specifications include a maximum propagation delay (tPD) of 5.0 ns and a maximum operating frequency (fCNT) of 182 MHz. It supports in-system programming via JTAG and includes features such as SpeedLocking for guaranteed fixed timing.

Complex Programmable Logic Devices Feature Summary

• High-speed performance with 5.0 ns tPD and 182 MHz fCNT using SpeedLocking technology.
• Flexible architecture with 32 macrocells, 32 I/Os, and 100% pin-out retention.
• Supports mixed-voltage system designs; 3.3-V devices accept 5-V inputs safely.
• JTAG (IEEE 1149.1) compliant for boundary scan testing and in-system programming.

Complex Programmable Logic Devices Applications

• PCI-compliant interface logic
• Mixed supply voltage system integration
• High-speed control applications requiring fixed timing

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'JNI' against the manufacturer's current package availability list, as lead-free options may have distinct suffixes. Confirm that the commercial temperature range (0°C to +70°C) aligns with the target application environment requirements before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 32 macrocells with a 1:1 macrocell-to-I/O ratio. Ensure the design fits within the 20 product term limit per output to utilize the guaranteed 5.0 ns tPD speed grade. Verify that the required package type matches the 'J' suffix designation in the official datasheet.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers densities from 32 to 512 macrocells. The M4A3 series specifically denotes 3.3-V operation, while the M4A5 series denotes 5-V operation. The '32/32' designation indicates the specific density and I/O configuration within the family.

Complex Programmable Logic Devices Replacement Considerations

Other members of the M4A3-32 family, such as M4A3-32-5JNI or M4A3-32-7JNI, offer different speed grades but share the same macrocell count and I/O structure. Cross-model replacements require verification of package compatibility and timing constraints.
