MCUs for smart meters

3 October 2012 DSP, Micros & Memory

Renesas Electronics announced the RX21A group of 32-bit microcontrollers (MCUs) with advanced functionality for smart meters. The new MCUs combine large Flash memory capacity of 512 KB and a 24-bit delta-sigma A/D converter for high-resolution measurement. The ICs implement power measurement, meter control, calculation of electricity charges and data encryption, and incorporate a real-time clock (RTC) with tamper sensor, temperature sensor and IrDA.3 compatibility. The ADC achieves conversion accuracy (SNDR) of 85 dB, and the encryption engine supports AES (256-bit key length). This provides smart meters with improved calculation precision and enhanced security functionality, such as communication data protection and unauthorised data access prevention.
