General Descriptions
N801-S is a low power small size synthesizable softcore of general purpose 32-bit embedded processor. With competitive small core size, high power efficiency and V3m ISA’s smaller code size, It is the best candidate to replace 8051 or other 8-bit MCU for cost and power sensitive applications that require small footprint and manageable power consumption.
N801-S is delivered with complete development package and small size MCU library for ease of integration in SoC design by simulation environment, as well as reference design flow to fit customer’s requirement in all aspects of performance, power consumption, cost and easy to use development tool and cost effective development board.
