ATSAM4CMP8中文资料Smart Energy SoC Products数据手册Microchip规格书

描述 Description

The Microchip's SAM4CMP8 is a system-on-chip solution for residential and poly-phase metering applications up to class 0.2 metrology accuracy over a dynamic range of 3000:1 and industrial temperature range. A seamless extension of Atmel's SAM4 family and SAM4C family of microcontrollers and solutions for smart grid security and communications applications, this metrology enabled device offer an unprecedented level of integration and flexibility with dual 32-bit ARM® Cortex®-M4 RISC processors providing maximum speed of 120 MHz each, 512Kbytes of embedded Flash, 152 Kbytes of SRAM and on-chip cache. The unique dual ARM Cortex-M4 architecture supports implementation of signal processing, application and communications firmware in independent partitions and offers an ability to extend program and data memory via parallel external bus interface (EBI) to ensure scalability of the design to meet future requirements.
