RL78 Family


RL78 - low power mcu, low power platform, 16 bit CISC architecture

RL78 is based upon a 16 bit CISC architecture with analogue rich functionality, delivering low power mcu platform consumption and high performance.

RL78 - low power mcu, low power platform, 16 bit CISC architectureIt is Renesas Electronics' next-generation microcontroller family combining advanced features from both the 78K and R8C families. The platform lineup includes general purpose, LCD and ASSPs including lighting and automotive microcontrollers. RL78 is designed specifically for ultra low power applications enabling customers to build compact and energy-efficient systems at lower cost.

RL78/D1x(Automotive Only)

Renesas is introducing the RL78/D1x as an optimized solution for the BRICs and low-end instrument cluster markets.
The RL78/D1x is the successor of 78K0/Dx2 or UPD78082x microcontrollers and suited for car instrument cluster, built-in car instrument cluster dedicated features such as Sound Generator, Stepper Motor Controller/Driver and LCD Segment Controller/Driver etc.

RL78/D1A(Automotive Only)


The RL78/F1x sophisticated MCU family is the successor of the both well known 78K0R/Fx3 and R8C/5x that realize low power consumption and high performance for a broad range of automotive applications.
