OM13006

OM13006 is a EM773 plug meter solution for energy metering. The EM773 is an ARM Cortex-M0 based, low cost 32bit energy metering IC, designed for 8/16bit 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 8/16bit architectures. The EM773 operates at CPU frequencies of up to 48MHz. The peripheral complement of the EM773 includes up to 32kB of flash memory, up to 8kB 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.

• EU Plug Version
• In-System Programming (ISP) and In-Application Programming (IAP) via on chip bootloader software
• Serial Wire Debug
• System tick timer
• GPIO pins can be used as edge and level sensitive interrupt sources
• Metrology Engine for Smart Metering with two current inputs and a voltage input
• UART with fractional baud rate generation, internal FIFO, and RS-485 support.
• SPI, I2C serial interface
• Unique device serial number for identification
• Integrated PMU to minimize power consumption during sleep, deep sleep, and deep power down modes
