Dual Core MCU and Companion AFE

At the core of Microchip’s smart energy platform is the Microchip SMART SAM4C series of products. The SAM4C4/8/16/32 are built around dual high performance 32-bit ARM Cortex-M4 core with maximum speed of 120 MHz, up to 2Mbyte of embedded Flash, 304 Kbytes of SRAM, and advanced security. This architecture allows for integration of application layer, communications layers, and metrology functions in a single device. It’s a modular approach that is sure to meet various design needs.

The ATSENSE-301, ATSENSE-201 and ATSENSE-101 are Analog Front End (AFE) devices targeting metrology applications. They feature up to 7 channels of high-precision sigma-delta ADCs with a 16ksps sample rate, a highly accurate, integrated Vref with 10 ppm/°C temperature stability, programmable current signal amplification, a temperature sensor and an SPI interface
