Introduction to NXP's LPC4300 Cortex-M4 based digi...
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.
