The WC16P332-16GX is a 32-bit microcontroller that includes high performance data manipulation features and peripheral subsystems. The WC16P332-16GX is comprised of standard modules that interface through a common intermodule bus (IMB). The WC16P332-16GX accommodates expedient development of devices which are tailored for specific applications.

 The WC16P332-16GX 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 WC16P332-16GX 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 WC16P332-16GX power consumption of the Microcontroller low. Power consumption can be greatly decreased by stopping the system clock. The Microcontrollerinstruction set includes a low-power stop (LPSTOP) command that easily implements this feature.
