RL78 is Renesas Electronics' next-generation microcontroller family combining advanced features from both the 78K and R8C families to deliver low power consumption (66μA / MHz) and high performance (41DMIPS @ 32MHz).
RL78 is based upon a 16-bit CISC architecture with analogue rich functionality. The platform line-up will include 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.
In addition to a high-precision (±1%) on-chip oscillator enabling 32MHz CPU operation and other standard on-chip functions from the RL78/G13, the RL78/G14 microcontrollers have multiply, divide and multiply-accumulate instructions capable of faster processing than the RL78/G13, and functions from the R8C Family with proven track records, such as timers RD/RG/RJ, data transfer controller, and event link controller, helping to lower the total cost of building a system and contributing to more compact size and lower power consumption.
