• Manufacturer Part Number: MACH4
• Description: High Performance E 2 CMOS In-System Programmable Logic
• Manufacturer: Lattice

Note:
1. Values in parentheses are for the M4(LV)-32/32 and M4(LV)-64/32.
This feature provides high flexibility for partitioning state machines and dual-phase clocks. It
also allows latches to be driven with either polarity of latch enable, and in a master-slave
configuration.
