User Flash Memory Block  
MAX V devices feature a single UFM block, which can be used like a serial EEPROM  
for storing non-volatile information up to 8,192 bits. The UFM block connects to the  
logic array through the MultiTrack interconnect, allowing any LE to interface to the  
UFM block. Figure 2–15 shows the UFM block and interface signals. The logic array is  
used to create customer interface or protocol logic to interface the UFM block data  
outside of the device. The UFM block offers the following features:  
Non-volatile storage up to 16-bit wide and 8,192 total bits  
Two sectors for partitioned sector erase  
Built-in internal oscillator that optionally drives logic array  
Program, erase, and busy signals  
Auto-increment addressing  
Serial interface to logic array with programmable interface
