User Flash Memory Block
UFM Block to Logic Array Interface
The UFM block is a small partition of the flash memory that contains the CFM block,
as shown in Figure 2–1 and Figure 2–2. The UFM block for the 5M40Z, 5M80Z,
5M160Z, and 5M240Z devices is located on the left side of the device adjacent to the
left most LAB column. The UFM blocks for the 5M570Z, 5M1270Z, and 5M2210Z
devices are located at the bottom left of the device. The UFM input and output signals
interface to all types of interconnects (R4 interconnect, C4 interconnect, and
DirectLink interconnect to/from adjacent LAB rows). The UFM signals can also be
driven from global clocks, GCLK[3..0]. The interface regions for the 5M40Z, 5M80Z,
5M160Z, and 5M240Z devices are shown in Figure 2–16. The interface regions for
5M570Z, 5M1270Z, and 5M2210Z devices are shown in Figure 2–17.

Notes to Figure 2–16:
(1) The UFM block inputs and outputs can drive to and from all types of interconnects, not only DirectLink interconnects
from adjacent row LABs.
