M4A3-32/32-10VI

Complex Programmable Logic Devices Overview

The M4A3-32/32-10VI is a 3.3-V ispMACH 4A Complex Programmable Logic Device (CPLD) featuring 32 macrocells and 32 user I/O options. It operates with a maximum propagation delay (tPD) of 10 ns and a counter frequency (fCNT) of 182 MHz. The device utilizes E2CMOS technology for in-system programming via JTAG (IEEE 1149.1). Key architectural features include SpeedLocking for guaranteed fixed timing, 100% pin-out retention, and support for mixed-voltage system designs.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS architecture with 5.0 ns to 10 ns tPD depending on speed grade.
• SpeedLocking feature ensures fixed timing performance up to 20 product terms per output.
• JTAG-compliant boundary scan testing and in-system programmability.
• Flexible logic allocator with synchronous/asynchronous modes and dedicated input registers.

Complex Programmable Logic Devices Applications

• PCI compliant interface logic
• Mixed supply voltage system integration
• Automated test equipment connectivity

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix '-10VI' against the manufacturer's current datasheet to confirm package type and temperature range. The source document lists speed grades but does not explicitly map the full part number string to a single package option. Ensure compatibility with existing design tools for the ispMACH 4A family.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 32 macrocells with guaranteed fixed timing. The -10 speed grade offers a 10 ns tPD, suitable for moderate-speed applications. Consider the 1:1 macrocell-to-I/O ratio which simplifies routing compared to 2:1 devices. Verify power consumption requirements against the static current specifications for the 3.3-V family.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4A family, which provides high-density PLD solutions ranging from 32 to 512 macrocells. The family is characterized by its flexible architecture, allowing for easy migration between density levels while maintaining pin-out compatibility. The M4A3 series specifically targets 3.3-V operation environments.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-32 variants with different speed grades or packages. Cross-family migration to ispMACH 4000ZE or MachXO series requires significant design re-verification due to architectural differences.
