Freescale Semiconductor announced the MCF51EM256, MC9S08LH64, and MC9S08GW64 microcontroller (MCU) reference designs for electricity and flow meters. Freescale’s microcontrollers enable smart meters to be designed with tamper detection mechanisms and real time usage monitoring. Freescale’s MCF51EM256 device for single and three-phase electricity meters are available now for suggested resale pricing of $3.97 (USD) for quantities of 10,000 units. The MC9S08LH64 devices are available for suggested resale pricing of $2.79 (USD) for quantities of 10,000 units. General availability of the MC9S08GW64 products will be announced later this year.
NEC Electronics introduced the 78K0/Lx3-M 8-bit All Flash LCD microcontrollers (MCUs). The 78K0/Lx3-M MCUs feature an integrated metrology engine that provides energy measurement and management functions for smart electricity meters. Samples of the new MCUs are scheduled for availability in January 2010. SPricing for 10,000-unit quantities starts at $3.45 each. Mass production is scheduled to begin in the second quarter of 2010.
