calculate current. The AG MOSFET gate driver pad turns the external MOSFET on and off. The AT pad
measures the load-side voltage level.
Embedded Memories
Flash Memory Blocks
The flash memory available in each Fusion device is composed of one to four flash blocks, each 2 Mbits
in density. Each block operates independently with a dedicated flash controller and interface. Fusion
flash memory blocks combine fast access times (60 ns random access and 10 ns access in Read-Ahead
mode) with a configurable 8-, 16-, or 32-bit datapath, enabling high-speed flash operation without wait
states. The memory block is organized in pages and sectors. Each page has 128 bytes, with 33 pages
comprising one sector and 64 sectors per block. The flash block can support multiple partitions. The only
constraint on size is that partition boundaries must coincide with page boundaries. The flexibility and
granularity enable many use models and allow added granularity in programming updates.
Fusion devices support two methods of external access to the flash memory blocks. The first method is a
serial interface that features a built-in JTAG-compliant port, which allows in-system programmability
during user or monitor/test modes. This serial interface supports programming of an AES-encrypted
stream. Data protected with security measures can be passed through the JTAG interface, decrypted,
and then programmed in the flash block. The second method is a soft parallel interface.
FPGA logic or an on-chip soft microprocessor can access flash memory through the parallel interface.
Since the flash parallel interface is implemented in the FPGA fabric, it can potentially be customized to
meet special user requirements. For more information, refer to the CoreCFI Handbook. The flash
memory parallel interface provides configurable byte-wide (×8), word-wide (×16), or dual-word-wide
