Memory Organization
The device has separate address spaces for program and data memory.
Program Flash Memory
There are two internal flash memory blocks in the device. The primary flash memory block (Block 0)
has 16/32 KByte. The secondary flash memory block (Block 1) has 8 KByte. Since the total program
address space is limited to 64 KByte, the SFCF[1:0] bit are used to control program bank selection.
Please refer to Figures 5 and 6 for the program memory configuration. Program bank selection is
described in the next section.
The 16K/32K x8 primary SuperFlash block is organized as 128/256 sectors, each sector consists of
128 Bytes.
The 8K x8 secondary SuperFlash block is organized as 64 sectors, each sector consists also of 128
Bytes.
For both blocks, the 7 least significant program address bits select the byte within the sector. The
remainder of the program address bits select the sector within the block.
