D3FP3

DESCRIPTION

The M32000D3FP is a new generation microcomputer with a 32-bit CPU and built- in high capacity DRAM. Using this device it is possible to implement the complex applications of the multimedia age with high performance and low power consumption.
The M32000D3FP contains 1M bytes of DRAM and 4K bytes of cache memory. The CPU is implemented with a RISC architecture and has a high performance figure of 52.4 MIPS (at an internal clock rate of 66.6 MHz ). Memory for main storage is provided internally to the device eliminating external memory and associated control circuits thus reducing overall system noise and power consumption.
