Description

32171 Group is a 32-bit, single-chip RISC microcomputer with built-in flash memory, which was developed for use in general industrial and household equipment.

To make full use of microcomputer built-in mass volume flash memory, this microcomputer contains a variety of peripheral functions ranging from two independent blocks of 16-channel A-D converters to 37-channel multifunction timers, 10-channel DMAs, 3-channel serial I/Os, and 1-channel real time debugger. Also included 1-channel Full-CAN modules and JTAG (boundary scan facility).

With lower power consumption and low noise characteristics also considered, these microcomputers are ideal for embedded equipment applications.
