Entry-level Low-Power 32-bit Processor

Overview

N705 is an ultra low-power small-size synthesizable general purpose 32-bit softcore embedded processor. With competitive small core size, high power-efficiency and small code size of the V3m ISA, it is the best candidate to replace 8051 and other 8-bit MCUs for small-footprint, cost and power sensitive applications.
For ease of integration in SoC design, it is delivered with a complete softcore development package as well as reference design flow to fit the requirements in all aspects of performance, power consumption, and cost. In addition, N705 is supported by user-friendly development tools, size-optimized MCU libraries and 2-wire low-cost ICE debugger.
