User Security
ProASICPLUS devices have FlashLock protection bits that,
once
programmed,
block
the
entire
programmed
contents from being read externally. Refer to Table 2-11
for details on the number of bits in the key for each
device. If locked, the user can only reprogram the device
employing the user-defined security key. This protects
the device from being read back and duplicated. Since
programmed data is stored in nonvolatile memory cells
(actually very small capacitors) rather than in the wiring,
physical deconstruction cannot be used to compromise
data. This type of security breach is further discouraged
by the placement of the memory cells beneath the four
metal layers (whose removal cannot be accomplished
without disturbing the charge in the capacitor). This is
the highest security provided in the industry. For more
information,
refer
to
Actel’s
Embedded Memory Floorplan
The embedded memory is located across the top and
bottom of the device in 256x9 blocks (Figure 1-1 on page
1-2). Depending on the device, up to 88 blocks are
available to support a variety of memory configurations.
Each block can be programmed as an independent
memory array or combined (using dedicated memory
routing resources) to form larger, more complex memory
configurations. A single memory configuration could
include blocks from both the top and bottom memory
locations.
Embedded Memory Configurations
The embedded memory in the ProASICPLUS family
provides great configuration flexibility (Table 2-12). Each
ProASICPLUS block is designed and optimized as a two-
port memory (one read, one write). This provides 198
kbits of two-port and/or single port memory in the
APA1000 device.
Each memory block can be configured as FIFO or SRAM,
with
independent
selection
of
synchronous
or
asynchronous
read
and
write
ports
Additional characteristics include programmable flags as
well as parity checking and generation. Figure 2-18 on
diagrams of the basic SRAM and FIFO blocks. Table 2-14
memory
block
SRAM
and
FIFO
interface
signals,
respectively. A single memory block is designed to
operate at up to 150 MHz (standard speed grade typical
conditions). Each block is comprised of 256 9-bit words
(one read port, one write port). The memory blocks may
be cascaded in width and/or depth to create the desired
memory organization. (Figure 2-20 on page 2-24). This
provides optimal bit widths of 9 (one block), 18, 36, and
72, and optimal depths of 256, 512, 768, and 1,024. Refer
to Actel’s SmartGen User’s Guide for more information.
Figure 2-21 on page 2-24 gives an example of optimal
memory usage. Ten blocks with 23,040 bits have been
used to generate three arrays of various widths and
depths. Figure 2-22 on page 2-24 shows how RAM blocks
can be used in parallel to create extra read ports. In this
example, using only 10 of the 88 available blocks of the
APA1000 yields an effective 6,912 bits of multiple port
RAM. The Actel SmartGen software facilitates building
wider and deeper memory configurations for optimal
memory usage.
