Based on Freescale’s new MCF51EM256 ColdFire MCU, a turnkey metering reference design is a cost-optimized implementation of a single-phase or three-phase smart electrical meter. Features include a 16-bit ADC with a programmable delay block, an independent real-time clock with calendaring function, dual secure flash memory banks, an automated meter reading interface, and an LCD driver.
