Memory organization

The STM8TL5xxx touch sensing Flash program memory is divided into 256 pages of 64

bytes each. It is organized in 32-bit words (4 bytes per word).

The memory array is divided into four areas:

•

The proprietary code area (PCODE)

•

The user boot code area (UBC)

•

The main program area

•

The data EEPROM (DATA)

The first two pages of the Flash program memory (starting from address 0x00 8000) contain

the interrupt vectors.

The devices also feature one block of option bytes (64 bytes) located a separate memory

array.

See Figure 4 for a description of the memory organization.
