NXP Semiconductors EM773 Energy Metering ICs

NXP Semiconductors EM773 ARM Cortex™-M0, 32-bit energy metering ICs are designed for 8- and 16-bit smart-metering applications. NXP EM773 energy metering ICs operate at CPU frequencies of up to 48 MHz and offer programmability and on-chip metrology functionality combined with a low-power, simple instruction set and memory addressing with reduced code size compared with existing 8- and 16-bit architectures. NXP Semiconductors EM773 energy metering ICs includes up to 32 kB of flash memory, up to 8 kB of data memory, up to 25 general purpose I/O pins, and a metrology engine for energy measurement.
