V2.1, 2008-08
1024 bytes (2
× 512 bytes) of the address space are reserved for the Special Function
Register areas (SFR space and ESFR space). SFRs are word-wide registers which are
used to control and monitor functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the XC2000 Family. In order to to ensure
upward compatibility they should either not be accessed or written with zeros.
In order to meet the requirements of designs where more memory is required than is
available on chip, up to 12 Mbytes (approximately, see Table 5) of external RAM and/or
ROM can be connected to the microcontroller. The External Bus Interface also provides
access to external peripherals.
768 Kbytes of on-chip Flash memory store code, constant data, and control data. The
on-chip Flash memory consists of up to three modules with a maximum capacity of 256
Kbytes each. Each module is organized in 4-Kbyte sectors.
The uppermost 4-Kbyte sector of segment 0 (located in Flash module 0) is used
internally to store operation control parameters and protection information.
Each sector can be separately write protected1), erased and programmed (in blocks of
128 Bytes). The complete Flash area can be read-protected. A user-defined password
sequence temporarily unlocks protected areas. The Flash modules combine 128-bit
read access with protected and efficient writing algorithms for programming and erasing.
Dynamic error correction provides extremely high read data security for all read access
operations. Access to different Flash modules can be executed in parallel.
For Flash parameters, please see Section 4.5.
1) To save control bits, sectors are clustered for protection purposes, they remain separate for
programming/erasing.
