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
speci鏗乧 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.
* This product is under development, is not quali鏗乪d or characterized and is subject to
change without notice.
