• Manufacturer Part Number: DSPIC33FJ12MC202
• Description: High-performance, 16-bit Digital Signal Controllers
• Manufacturer: Microchip Technology Inc.

3.0
The dsPIC33FJ12MC201/202 architecture features
separate program and data memory spaces and
buses. This architecture also allows the direct access
of program memory from the data space during code
execution.

3.1
The
dsPIC33FJ12MC201/202 devices is 4M instructions.
The space is addressable by a 24-bit value derived
either from the 23-bit Program Counter (PC) during
program execution, or from table operation or data
space remapping as described in Section 3.6
“Interfacing Program and Data Memory Spaces”.
User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). The exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.
The memory map for the dsPIC33FJ12MC201/202
devices is shown in Figure 3-1.
