Renesas Electronics Europe Delivers RL78/I1C Group of Microcontrollers for Smart Meters
DÃSSELDORF, Germany, November 7, 2016 /PRNewswire/ --
MCUs with Enhanced Security Function and Arithmetic Operation Performance to Realize
Wide Range of Power Meter Platforms, from 1-ph to 3-ph
The new RL78/I1C MCUs are available in seven versions, with on-chip memory capacities
ranging from 64 kilobytes (KB) for low-end single-phase meters, 128 KB for high-end
single-phase meters, and 256 KB for three-phase meters; and package pin counts from 64
pins for space-saving needs, 80 pins for single-phase meters aimed for use in emerging
countries, to 100 pins for single-phase meters aimed for use in advanced applications.
Key features of the RL78/I1C Group of MCUs:Â
1) Ability to implement electric power measurement processing and DLMS processing on a
single chipÂ
The RL78/I1C integrates an AES (Note 2) hardware engine for this purpose, implementing
in hardware the AES GCM (Note 3) mode required by the DLMS standard. In addition, the
on-chip phase-locked loop (PLL) boosts the maximum operating frequency from 24 megahertz
(MHz) to 32 MHz, and the 32-bit multiplier/multiply-and-accumulate unit dramatically
reduces the load imposed by software power calculation with 24-bit data converted by the
24-bit DELTASUMMATIONs A/D converter.
2) Support for three-phase, four-wire metersÂ
The event link controller function and phase adjustment function coordinate the
operation of the four-channel 24-bit DELTASUMMATION A/D converter and three-channel 10-bit
Successive Approximation Register (SAR) A/D converter, enabling current and voltage
measurement on seven channels.
3) Evaluation and reference kit Â
The reference kit can be used in the meter development phase to reduce the time
required for development.
Availability Â
Mass production started in August 2016. (Availability is subject to change without
notice.)
The European launch of the RL78/I1C will take place at the European Utility Week from
November 15th to 17th 2016 in Barcelona on Stand 3G141.
Please refer to the separate sheet of the RL78/I1C.
Note 1) DLMS = Device Language Message Specification
Note 2) AES = Advanced Encryption Standard
Note 3) GCM = Galois/Counter Mode
