User Flash Memory Block  
UFM Storage  
Each device stores up to 8,192 bits of data in the UFM block. Table 2–3 lists the data  
size, sector, and address sizes for the UFM block.

There are 512 locations with 9-bit addressing ranging from 000hto 1FFh. The sector 0  
address space is 000hto 0FFhand the sector 1 address space is from 100hto 1FFh. The  
data width is up to 16 bits of data. The Quartus II software automatically creates logic  
to accommodate smaller read or program data widths. Erasure of the UFM involves  
individual sector erasing (that is, one erase of sector 0 and one erase of sector 1 is  
required to erase the entire UFM block). Because sector erase is required before a  
program or write operation, having two sectors enables a sector size of data to be left  
untouched while the other sector is erased and programmed with new data.  
Internal Oscillator  
As shown in Figure 2–15, the dedicated circuitry within the UFM block contains an  
oscillator. The dedicated circuitry uses this oscillator internally for its read and  
program operations. This oscillator's divide by 4 output can drive out of the UFM  
block as a logic interface clock source or for general-purpose logic clocking. The  
typical OSC output signal frequency ranges from 3.9 to 5.3 MHz, and its exact  
frequency of operation is not programmable.  
The UFM internal oscillator can be instantiated using the MegaWizardPlug-In  
Manager. You can also use the MAX II/MAX V Oscillator megafunction to instantiate  
the UFM oscillator without using the UFM memory block.
