CDR3 Flash (UC3F) EEPROM
The UC3F EEPROM module array is divided into array blocks to allow for independent erase, address
attributes restrictions, and protection from program and erase for each array block. The size of a large array
block in the UC3F module is fixed at 64 Kbytes. The size of a subdivided large block becomes the original
large array block size minus 16 Kbytes (64 Kbytes – 16 Kbytes = 48 Kbytes). The size of the small block,
which is the remainder of the large block, is always 16 Kbytes. The total UC3F EEPROM array is
distributed into eight large blocks, two of which contain small blocks. Information is transferred to the
UC3F EEPROM by long-word (64 bits), word (32 bits), half-word (16 bits), or byte (8 bits).
To improve system performance, each array read access retrieves 32 bytes of information. These 32 bytes
may be copied into one of two read page buffers aligned to the low order addresses. The two read page
buffers are independently updated by page management logic contained in the BIU which interfaces to the
UC3F EEPROM module.
