size, sector, and address sizes for the UFM block.
Table 2–3. UFM Array Size
There are 512 locations with 9-bit addressing ranging from 000h to 1FFh. The sector 0
address space is 000h to 0FFh and the sector 1 address space is from 100h to 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.
As shown in
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 MegaWizard
Manager. You can also use the MAX II/MAX V Oscillator megafunction to instantiate
the UFM oscillator without using the UFM memory block.
