7.3 UDB Array Description
Figure 7-11
the array core, there are a DSI routing interfaces at the top and
bottom of the array. Other interfaces that are not explicitly shown
include the system interfaces for bus and clock distribution. The
UDB array includes multiple horizontal and vertical routing
channels each comprised of 96 wires. The wire connections to
UDBs, at horizontal/vertical intersection and at the DSI interface
are highly permutable providing efficient automatic routing in
PSoC Creator. Additionally the routing allows wire by wire
segmentation along the vertical and horizontal routing to further
increase routing flexibility and capability.

a bank of 16 UDBs. The primary programmable resources of the
UDB are two PLDs, one datapath and one status/control register.
These resources are allocated independently, because they
have independently selectable clocks, and therefore unused
blocks are allocated to other unrelated functions.
An example of this is the 8-bit Timer in the upper left corner of
the array. This function only requires one datapath in the UDB,
and therefore the PLD resources may be allocated to another
function. A function such as a Quadrature Decoder may require
more PLD logic than one UDB can supply and in this case can

Programmable resources in the UDB array are generally
homogeneous so functions can be mapped to arbitrary
boundaries in the array.

7.4 DSI Routing Interface Description
The DSI routing interface is a continuation of the horizontal and
vertical routing channels at the top and bottom of the UDB array
core. It provides general purpose programmable routing
between device peripherals, including UDBs, I/Os, analog
peripherals, interrupts, DMA and fixed function peripherals.

other device peripherals. Any digital core or fixed function
peripheral that needs programmable routing is connected to this
interface.
