描述 Description

Overview Archived content is no longer updated and is made available for historical reference only.
The EM783-SC/SP/TP/MC3/MC6 is an ARM Cortex-M0-based, low-cost 32-bit family ofapplication processors, designed for energy measurement and monitoring applications.The EM783 offers programmability and on-chip metrology functionality combined with alow power, simple instruction set. It also has memory addressing together with reducedcode size compared to existing 8/16-bit architectures.
The EM783 operate at CPU frequencies of up to 48 MHz.
The digital peripherals on the EM783 include:32 kB of flash memory
4 kB of EEPROM data memory
8 kB of SRAM data memory
Fast-mode Plus I²C-bus interface
RS-485/EIA-485 USART
One SSP controller
Two general-purpose counter/timers
Up to 22 general-purpose I/O pins

A metrology engine with built-in temperature sensor is used for energy measurements. A10-bit DAC and an internal voltage reference are also available.
