The NR4600/NR4700/NR5000 series are 64bit microprocessors and its chip sets feature high performance, low cost and low power consumption. The NR4650/NR4645 is another member of this series. A derivative of the NR4600, it incorporates new instruction sets to achieve better cost performance for embedded applications. NKK is also committed to providing development environments. ---------------- L1 Cache: 16K MIPS ISA: III Max clock: 166MHz
