MC1322x Technical Data, Rev. 1.3

Freescale Semiconductor
4Memory
The MC1322x memory resources consist of RAM, ROM, and serial FLASH.
4.1
RAM and ROM
The RAM and ROM features include:
96 Kbytes RAM.
— RAM0: 8 Kbytes, 2 Kwords (2048 x 32 bits)
— RAM1: 24 Kbytes, 6 Kwords (6144 x 32 bits)
— RAM2: 32 Kbytes, 8 Kwords (8192 x 32 bits)
— RAM3: 32 Kbytes, 8 Kwords (8192 x 32 bits)
All read or write accesses require a minimum of two system clock cycles
Stall signal generated for read after write cycles
Clock is enabled only on the accessed memory device for low power consumption
RAMs have been divided to allow for power savings. While sleeping, the above RAM blocks can
be turned off (combinations include 8, 32, 64, and 96 Kbytes active) and the RAM remainder can
be placed in a low voltage mode for data retention. If more RAMs are turned on, then less battery
life will be achieved. Depending on the amount of RAM powered during sleep, the boot time may
be longer with less RAM as the non-powered RAM must be reloaded from FLASH.
80 Kbytes ROM
— 20 Kwords (20480 x 32 bits)
— Initially contains bootstrap code, 802.15.4 MAC and drivers. The MAC software builds on the
lower level hardware capability of the transceiver and MACA. All code except the bootstrap is
“patchable”.
4.2
Serial FLASH (NVM)
The MC1322x also contains a 128 Kbyte serial FLASH memory that can be mirrored into the 96 Kbyte
RAM. The serial FLASH is accessed via an internal dedicated SPI module (SPIF). The FLASH erase,
program, and read capability are programmed through the SPIF port. The FLASH is accessed at boot time
to load/initialize RAM. All actual CPU program and data access is from RAM or ROM.
