RL78/I1C

Renesas introduces the RL78/I1C - Industry’s lowest power microcontrollers for high-end Smart electricity meter market!

 

RL78/I1C microcontrollers feature integrated functions for high precision smart electricity metering, such as 24-bit Delta-Sigma A/D operation, AES H/W integration, up to 256 KB flash line-up, a 32-bit MAC (Multiply and Accumulation) function, independent power supply for RTC and enhance battery pin (Vbat) function for AC-off operation, and Hardware zero cross detection. Performance is enhanced with a high temperature coefficient internal reference voltage. A segment LCD driver supports 8-COM.
