DESCRIPTION
The WC16P332 is a 32-bit microcontroller that includes high
performance data manipulation features and peripheral
subsystems. The WC16P332 is comprised of standard modules
that interface through a common intermodule bus (IMB). The
WC16P332 accommodates expedient development of devices
which are tailored for specific applications.
The Microcontroller includes a 32-bit CPU (CPU32), a system
integration module (SIM), a time processor unit (TPU), a queued
serial module (QSM), and a 2Kx8 SRAM module with TPU
emulation capability.
The Microcontroller can either synthesize an internal clock
signal from an external reference or use an external clock input
directly. Operation with a 32.768khz reference frequency is
standard. System hardware and software allow changes in
clock rate during operation. The Microcontroller module
operation is fully static, therefore register and memory
contents are not affected by clock rate changes.
HCMOS technology makes the typical power consumption of
the Microcontroller low. Power consumption can be greatly
decreased by stopping the system clock. The Microcontroller
instruction set includes a low-power stop (LPSTOP) command
that easily implements this feature.
