5 Memory organization
The CPU uses a Harvard architecture, so that memory is organized in two separated fields:
program memory and data memory. As both memories are separated, the central processing
unit can read/write data at the same time it loads an instruction. Peripherals and system control
registers are mapped on data memory space.
Program memory is made in one page. Data is made of several 256 bytes pages.
5.1 Program memory
The program memory is implemented as Multiple Time Programmable (MTP) Flash memory
or ROM. The power consumption of MTP memory is linear with the access frequency (no sig-
nificant static current).
Size of the MTP Flash memory is 8192 x 22 bits (= 22 kBytes)
Size of the ROM memory is 6144 x 22 bits (= 17 kBytes)

5.2 Data memory
The data memory is implemented as static Random-Access Memory (RAM). The RAM size is
512 x 8 bits plus 8 low power RAM bytes that require very low current when addressed. Pro-
grams using the low-power RAM instead of RAM will use even less current.
