• Manufacturer Part Number: mc9s12xd256
• Description: Hcs12x Microcontrollers
• Manufacturer: Freescale Semiconductor, Inc

Freescale Semiconductor
The MCU FLASHSIZE is 64 Kbytes (0x10000) and MCU RAMSIZE is 32 Kbytes (0x8000).
The XGATE RAMSIZE is 16 Kbytes (0x4000).
The space occupied by the XGATE RAM in the global address space will be:
XGATE accesses to local address range 0x0800–0xBFFF will result in accesses to the following
FLASH block in the global address space:
Bottom address: (0x10_0000 minus 0x4000) = 0x0F_C000
Top address: 0x0F_FFFF
Bottom address: 0x78_0800
Top address: (0x78_FFFF minus 0x4000) = 0x78_BFFF
