SAM4CM SERIES Dual Arm® Cortex®-M4 Core SOC with Integrated Metrology AFE and Advanced Security Features for Residential and C&I Smart Meters Description The Microchip SAM4CM series represents a family of system-on-chip solutions for residential and polyphase metering applications. The devices offer up to class 0.2 metrology accuracy over a dynamic range of 3000:1 within the industrial temperature range and are pliant with ANSI C12.20-2002 and IEC 62053-22 standards. A seamless extension of Microchip’s SAM4, SAM4CP and SAM4C family of microcontrollers and solutions for smart grid security and munications applications, these metrology-enabled devices offer an unprecedented level of integration and flexibility with dual 32-bit ARM® Cortex®-M4 RISC processors running at a maximum speed of 120 MHz each(1), up to 2 Mbytes of embedded Flash, 304 Kbytes of SRAM and on-chip cache. The unique dual ARM Cortex-M4 architecture supports implementation of signal processing, application and munications firmware in independent partitions, and offers the ability to extend program and data memory via parallel external bus interface (EBI) to ensure scalability of the design to meet future requirements. The peripheral set includes metrology-specific precision voltage reference, up to seven (7) simultaneously sampled Sigma-Delta ADC subsystems supporting three (3) voltage and four (4) current measurement channels (polyphase versions only), an extensive set of embedded cryptographic Features , anti-tamper, Floating Point Unit (FPU), four USARTs, two UARTs, two TWIs, four SPIs, three 16-bit PWMs, two 3-channel general-purpose 16-bit timers, 6-channel 10-bit ADC, battery-backed RTC with <1 µA consumption and a 38 x 6 segmented LCD controller. To ensure the distinct separation of metrology and application or munication functions, the SAM4CM integrates a dedicated Cortex-M4F core that manages all necessary metrology resources and memory.  2022 Microchip Technology...
