General description
The EM773 is an ARM Cortex-M0 based, low-cost 32-bit energy metering IC, designed for
8/16-bit smart metering applications. The EM773 offers programmability and on-chip
metrology functionality combined with a low power, simple instruction set and memory
addressing with reduced code size compared to existing 8/16-bit architectures.
The EM773 operates at CPU frequencies of up to 48 MHz.
The peripheral complement of the EM773 includes up to 32 kB of flash memory, up to
8 kB of data memory, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 UART,
one SPI interface with SSP features, three general purpose counter/timers, up to 25
general purpose I/O pins, and a metrology engine for energy measurement.
