32-/16-BIT MICROPROCESSOR
The
μ
PD70741 (V821) is a 32/16-bit RISC microprocessor that uses, as its processor core, the high-
performance 32-bit microprocessor
μ
PD70732 (V810
TM
) designed for built-in control applications. It incorporates
peripheral functions such as a DRAM/ROM controller, 2-channel DMA controller, real-time pulse unit, serial
interface, and interrupt controller.
The V821, which offers quick real-time response, high-speed integer instructions, bit string instructions, and
floating-point instructions, is ideally suited to use in OA equipment such as printers and facsimiles, image
processing devices such as those used in navigation units, portable devices, and other devices demanding
excellent cost performance.
The functions are described in detail in the following User’s Manuals, which should be read before
starting design work.
