EM783-TP: Energy metering IC; 32 kB flash, 8 kB SRAM, 4 kB EEPROM ARCHIVED

The EM783-SC/SP/TP/MC3/MC6 is an Arm^® Cortex^®-M0-based, low-cost 32-bit family of application processors, designed for energy measurement and monitoring applications. The EM783 offers programmability and on-chip metrology functionality combined with a low power, simple instruction set. It also has memory addressing together with reduced code 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. A 10-bit DAC and an internal voltage reference are also available.
