EM783-MC6E

Application Specific Microcontrollers Overview

The EM783-MC6E is a multi-channel application processor for energy measurement, built on an ARM Cortex-M0 core running at up to 48 MHz. It features a metrology engine with 2% accuracy and supports six current channels with one voltage channel. The device includes 24 kB of flash memory, 6.5 kB of SRAM, and 4 kB of EEPROM for calibration data. Integrated peripherals include UART, SPI, I2C, GPIOs, and timers. A built-in temperature sensor provides accuracy within 3 °C.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'E' against official documentation to confirm package type or environmental rating. Ensure the selected variant matches the required number of I/U channels and accuracy specifications for the target application.

Application Specific Microcontrollers Selection Notes

Select the EM783-MC6E when six current channels are required. Note that this variant offers 2% accuracy compared to the 1% accuracy available in single-channel (SC) and single-phase (SP) models. Verify that the 6.5 kB SRAM and 24 kB Flash meet the firmware requirements.

Application Specific Microcontrollers Part Context

The EM783-MC6E belongs to the EM783 family of low-cost application processors designed for energy measurement. This family utilizes the ARM Cortex-M0 architecture and integrates a dedicated metrology engine to simplify the design of billing-grade and industrial power monitoring systems.
