Product Overview:
The 32185 Group is a 32-bit, single-chip RISC microcomputer with built-in flash memory. To accomplish high-precision arithmetic operations, it incorporates a fully IEEE754 compliant, single-precision FPU. This microcomputer contains a variety of peripheral functions. With the software necessary to run these peripheral functions stored in its large-capacity flash memory, this microcomputer meets the needs of application systems for high functionality, high-performance arithmetic capability, and sophisticated control, thereby adaptation to the embedded applications can be easily configured.
