MC68332
USER’S MANUAL
The MC68332, a highly-integrated 32-bit microcontroller, combines high-performance
data manipulation capabilities with powerful peripheral subsystems. The MCU is built
up from standard modules that interface through a common intermodule bus (IMB).
Standardization facilitates rapid development of devices tailored for specific applica-
tions.
The MCU incorporates a 32-bit CPU (CPU32), a system integration module (SIM), a
time processor unit (TPU), a queued serial module (QSM), and a 2-Kbyte static RAM
module with TPU emulation capability (TPURAM).
The MCU can either synthesize an internal clock signal from an external reference or
use an external clock input directly. Operation with a 32.768-kHz reference frequency
is standard. System hardware and software allow changes in clock rate during opera-
tion. Because MCU operation is fully static, register and memory contents are not af-
fected by clock rate changes.
High-density complementary metal-oxide semiconductor (HCMOS) architecture
makes the basic power consumption of the MCU low. Power consumption can be min-
imized by stopping the system clock. The CPU32 instruction set includes a low-power
stop (LPSTOP) command that efficiently implements this capability.
Documentation for the Modular Microcontroller Family follows the modular construc-
tion of the devices in the product line. Each microcontroller has a comprehensive us-
er's manual that provides sufficient information for normal operation of the device. The
user's manual is supplemented by module reference manuals that provide detailed in-
formation about module operation and applications. Refer to Freescale publication Ad-
vanced Microcontroller Unit (AMCU) Literature (BR1116/D) for a complete listing of
documentation.
