ProASIC3 Flash Family FPGAs
User Nonvolatile FlashROM
ProASIC3 devices have 1 kbit of on-chip, user-accessible, nonvolatile FlashROM. The FlashROM can
be used in diverse system applications:
• Internet protocol addressing (wireless or fixed)
• System calibration settings
• Device serialization and/or inventory control
• Subscription-based business models (for example, set-top boxes)
• Secure key storage for secure communications algorithms
• Asset management/tracking
• Date stamping
• Version management
The FlashROM is written using the standard ProASIC3 IEEE 1532 JTAG programming interface. The
core can be individually programmed (erased and written), and on-chip AES decryption can be used
selectively to securely load data over public networks (except in the A3P015 and A3P030 devices), as in
security keys stored in the FlashROM for a user design.
The FlashROM can be programmed via the JTAG programming interface, and its contents can be read
back either through the JTAG programming interface or via direct FPGA core addressing. Note that the
FlashROM can only be programmed from the JTAG interface and cannot be programmed from the
internal logic array.
The FlashROM is programmed as 8 banks of 128 bits; however, reading is performed on a byte-by-byte
basis using a synchronous interface. A 7-bit address from the FPGA core defines which of the 8 banks
and which of the 16 bytes within that bank are being read. The three most significant bits (MSBs) of the
FlashROM address determine the bank, and the four least significant bits (LSBs) of the FlashROM
address define the byte.
The ProASIC3 development software solutions, Libero® System-on-Chip (SoC) and Designer, have
extensive support for the FlashROM. One such feature is auto-generation of sequential programming
files for applications requiring a unique serial number in each part. Another feature allows the inclusion of
static data for system version control. Data for the FlashROM can be generated quickly and easily using
Libero SoC and Designer software tools. Comprehensive programming file support is also included to
allow for easy programming of large numbers of parts with differing FlashROM contents.
SRAM and FIFO
ProASIC3 devices (except the A3P015 and A3P030 devices) have embedded SRAM blocks along their
north and south sides. Each variable-aspect-ratio SRAM block is 4,608 bits in size. Available memory
configurations are 256×18, 512×9, 1k×4, 2k×2, and 4k×1 bits. The individual blocks have independent
read and write ports that can be configured with different bit widths on each port. For example, data can
be sent through a 4-bit port and read as a single bitstream. The embedded SRAM blocks can be
initialized via the device JTAG port (ROM emulation mode) using the UJTAG macro (except in A3P015
and A3P030 devices).
In addition, every SRAM block has an embedded FIFO control unit. The control unit allows the SRAM
block to be configured as a synchronous FIFO without using additional core VersaTiles. The FIFO width
and depth are programmable. The FIFO also features programmable Almost Empty (AEMPTY) and
Almost Full (AFULL) flags in addition to the normal Empty and Full flags. The embedded FIFO control
unit contains the counters necessary for generation of the read and write address pointers. The
embedded SRAM/FIFO blocks can be cascaded to create larger configurations.
PLL and CCC
ProASIC3 devices provide designers with very flexible clock conditioning capabilities. Each member of
the ProASIC3 family contains six CCCs. One CCC (center west side) has a PLL. The A3P015 and
A3P030 devices do not have a PLL.
The six CCC blocks are located at the four corners and the centers of the east and west sides.
All six CCC blocks are usable; the four corner CCCs and the east CCC allow simple clock delay
operations as well as clock spine access.
