DESCRIPTION
16 MHz Operating Frequency
Single 5V Operation
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.
System Integration Module (SIM)
• External Bus Support
• Programmable Chip-Select Outputs
• System Protection Logic
• Watchdog Timer, Clock Monitor, and Bus Monitor
• System Protection Logic
• System Clock Based on 32.768kHz Crystal for Low Power
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.
Operation
• Test/Debug Submodule for Factory/User Test and
Development
ꢀ
Central Processing Unit (CPU)
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
• Upward Object Code Compatible
• New Instructions for Controller Applications
• 32-Bit Architecture
• Virtual Memory Implementation
• Loop Mode of Instruction Execution
• Table Lookup and Interpolate Instruction
• Improved Exception Handling for Controller Applications
• Trace on Change of Flow
• Hardware Breakpoint Signal, Background Mode
• Fully Static Operation
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.
