Technical Summary
32-Bit Modular Microcontroller
1 Introduction
The MC68334, a highly-integrated 32-bit microcontroller, combines high-performance data manipula-
tion 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 applications.
The MCU incorporates a 32-bit CPU (CPU32), a system integration module (SIM), an 8/10-bit analog-
to-digital converter (ADC), a time processor unit (TPU) and a 1-Kbyte static RAM module with TPU em-
ulation 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. The maximum sys-
tem clock speed is 20.97 MHz. System hardware and software allow changes in clock rate during op-
eration. Because MCU operation is fully static, register and memory contents are not affected 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 minimized by stopping the system clock. The
CPU32 instruction set includes a low-power stop (LPSTOP) command that efficiently implements this
capability.
