New 32bit mcus offer 'industry leading' low power consumption says NEC
1 min read
A total of 78 new 32bit microcontrollers have been announced by NEC Electronics, with what it describes as 'industry leading low power consumption'
The 32bit All Flash V850ES/Jx3 series microcontrollers are suitable for use in battery driven systems such as polyphase electricity meters and handheld terminals, connected devices such as USB2.0 PC peripherals and healthcare equipment.
According to NEC, designers can choose the optimum configuration from a single family for a range of applications. By sharing the same architecture, NEC says the mcus enable easy migration of software and hardware for the system designers.
The V850ES/Jx3-L mcus operate at 20 MHz and require 0.9milliwatts per million instructions per second a 60% reduction over the company's existing mcus. Further features include up to 512Kb of flash memory and optional on chip USB 2.0 controllers.
The 40 pin mcus are equipped with 6 x 6 x 0.75mm quad flat package and the 48pin versions in 7 x 7 x 0.75mm quad flat no leads packages. By employing QFN packages, NEC says it has succeeded in reducing the number of external pins by 50% and the package thickness by 46%, achieving an 82% smaller package size compared to the company's existing mcus.
Mass production of the new devices is scheduled to begin in June 2010.
