The RL78 family is the new generation of power-efficient microcontrollers from Renesas. RL78 application fields The RL78 family is utilized in a wide variety of applications. It enables customers to build compact and energy-efficient systems at lower cost. The RL78 is a new generation of power-efficient microcontrollers that combine the excellent CPU performance of the 78K0R with the superior on-chip functions of the R8C and 78K. It delivers higher performance and lower power consumption than previous microcontrollers while enabling customers to utilize software resources developed for the...

Broad Scalability New SNOOZE mode for more power savings In SNOOZE mode the CPU is halted while A/D conversion and data reception are enabled. By transitioning from STOP mode (clock stopped) to SNOOZE mode, it is possible to start the on-chip oscillator and operate peripheral functions while the CPU remains inactive. MAIN RUN CPU Peripheral function SNOOZE Peripheral function A/D conversion, serial data reception, multiply and divide operations, multiply-accumulate operations, and DMA operations are possible. Peripheral function Power consumption can be reduced even more than in HALT mode....
